DAVIS NEW KEY-SEATING MACHINE.

Davis Key-Seat Cutting Machine.

We illustrate herewith a new key-seat cut-ting machine, with details, as made by Wil liam P. Davis, North Bloomfield, N. Y. The perspective engraving represents the machine, complete, as in the operation of cut-ting a key-way in a pinion, while upon the floor are seen specimens of finished work. The construction and operation of this ma-chine will be apparent from the lettered de-tail engravings. In Fig. 1 the machine is shown to consist principally of a cast-iron box or frame A, which contains the mechanism for operat-ing the cutter. Fig. 2 is a plan, and Fig. 3 a vertical sec-tion through line, x, x, Fig. 2 showing the driving mechanism. This machine is adapted chiefly for cutting key-ways in the hubs of wheels and pulleys. Such work to be operated upon is placed upon the table B, to which it is firmly se-cured by the clamp C and the stud bolts, g, g'. These stud-bolts are sufficiently long to admit the largest work intended to be done upon this machine. The studs are well sup-plied with collars, h, h', which enable the operator to adjust the clamp at any desired height from the table. Work of various diameters may be accom-modated by means of extra holes in the table and slots in the clamp C, for spreading

These blocks may be adjusted by means of bolts placed in the radial rows of holes, z, z. The details of these chucks will be compre-hended from an inspection of Figs. 6, 7, 8 and 9. X is the collared set screw for holding the block ; Y is a pin that fits in a hole in the table. The block, which bears against the work, is adjusted by the set screw U. This machine was designed for use in shops where it would not pay to purchase a slotting machine to do such work, and a planer could not be spared; besides a planer, would be too unhandy for much of the work that could be done with ease and very ex-peditiously upon one of these machines. Furthermore, this machine is adapted to various kinds of work which are not herein alluded to.


 


Pg 172 HANDLING AT FURNACES. BY WALDON FAWCETT. In few sections of the industrial field has the past few years witnessed an advance which has been as revolutionary in its influence upon methods and equipment as in the handling of iron ore at the blast furnaces, where its conversion into pig iron constitutes 
the first step in iron and steel manufacture, to the general interpretation of the term. A since it was the custom to transfer by hand the ore, 
coke, limestone and other ingredients of the furnace "charge" from the rail-road cars to wheelbarrows, by which, supplemented by elevators of antiquated de-sign, the raw material was conveyed slowly and laboriously to the top of the furnace. Under the new system mechanical devices perform automatically al-most every function which 
was formerly dependent upon human labor. The bridge tramways, equipped with hoisting and conveying apparatus for the movement at high speed of tubs or buckets of over a ton capacity, which have proven so successful in unloading ore from vessels on the Great Lakes, and the car-dumping ma- • chines which have come into extensive use for placing large consignments of coal on board vessels expeditiously, have both been utilized for handling ore at furnaces; and in some in-stances these two exceptionally interesting classes of machinery have been used in conjunction. This is the case at the plants of the National Steel Company at Youngstown, Ohio, arid Mingo Junction, Ohio, and the Neville Island plant of the American Steel and Wire Company. It has been demonstrated at these institutions that under almost any conditions ore can be handled from railway car to ore-pit or from ore-pit to bins at an average of less than one cent a ton. In order to convey an adequate idea of the scope of a representative installation of this character, it may be stated that the stock yard is from 700 to 1,000 feet in length with a width of 250 feet between opposite

walls and has a capacity of from 750,000 to 1,000,000 tons of ore. The yard is spanned by two steel conveyor bridges which an the largest of their type ever con-structed. Each bridge in addition to the span of 260 feet has a cantilever extension over the bins of 41 feet. Each bridge is mounted on a two-track ma-chine tower at its outer or receiving end and on a one-track rear tower next to the furnaces. At their receiving ends the bottom chords of the bridges are

an unobstructed view of the ore cars as they move on the bridge, for this apparatus, it should be explained, delivers ore to the stock piles in small cars instead of buckets. The car-dumping machine, which constitutes an im-portant feature of the installation, is located at a point easily reached from the storage yard in which the regular railroad cars loaded with ore are received. The car-dumper is located on the summit of a slight incline, and in a pit below the loaded car as it

approximately 54 feet above the bottom of the ore-pit and at the rear tower 80 feet, thus giving very large storage capacity. The bridges travel along their tracks at a speed of fifty feet a minute by means of gearing driven by two 130 horse power electric motors on each bridge. These motors also furnish the power for handling the ore on the bridges, as well as in rehandling it from the stock pile, suitable drums and gearing being connected with the motors. The motors take their cur-rent from an overhead trolley above the machinery tower. The operating machinery is located overhead in the main tower, and an operator's house is placed next to the bridge in a position giving the operator

A push-bar on the disapearing car engages the drawhead of the ore car, pushing it up grade into the car-dumper. The car-dumper consists of a substantial steel structure on which is a plat-form to receive the loaded. car. This platform is -pivoted at one side, and when the platform with the car load of ore is rotated around this axis, the car is raised sufficiently high to discharge the ore over an apron into four small steel cars of seventeen tons capacity each, mount-ed on a transfer car along-side the car-dumper. To insure the equal distribution of the ore in the four smaller cars, movable de-flectors are pivoted to the apron of the car dumper. These are moved by a steam cylinder with cataract locking cylinder, both being under the control of the operator. By means of this machine gondola, wood or steel hopper bottom cars of twenty to sixty tons capacity can be handled. The car dumper may be operated either by steam engines or electric motors. After the loaded car is run into the car-dumper the operator sets the deflector for either a short hopper car with ore loaded nearly uniform throughout the car or for a long gondola with ore loaded at either end over the trucks, as the case may be. The 17-ton cars which receive the ore from the car-dumper are of the side-dump pattern. The transfer

A MACHINIST 1883,

JUNE 2, 1883.] AMERICAN" MACHINIST Programme for Meeting of the Mechanical Engineers. The secretary of the American Society of Mechanical Engineers, F. R. Hutton, has is-sued a circular to members giving a pro-gramme for the meeting at Cleveland, 0., beginning June 12th. We make the follow-ing extracts: LOCAL COMMITTEE OF ARRANGEMENTS. J. F. Holloway, Chairman. C. F. Brush, S. T. Wellman, W. M. Barr, Ambrose Swasey, N. S. Possons, W. H. Thompson, E. H. Martin, John Walker, J. D. Cox, Jr., W. R. Warner, F. H. Richards. EXECUTIVE COMMITTEE. S. T. Wellman, J. F. Holloway, Ambrose Swasey, J. D. Cox, Jr. The sessions of the society will be held in the rooms of Cleveland Vocal Society, City Hail, Superior street.

General business, reading of papers and conversazione. It is hoped that this meeting will be largely at-tended, in order that visiting members as well as newly-elected members may become acquainted with each other. The Local Com-mittee have extended an invitation to the Civil Engineers' Club of Cleveland, to be present at the opening meeting, in order to add to the pleasure and the sociability of the occasion. Second Day- Wednesday, June 13. Morning session, 10 A. M. Reading of professional papers and general discussions. Afternoon session, 2.30 P. M. Reading of papers and discussion continued. In the evening the members are invited to a recep-tion given to the society by citizens of Cleve-land. Third Day-Thursday, June 14. The day will be devoted to excursions by special train among the prominent iron and steel works and the large manufactories of Economy in the Management of Locomotives. BY LEWIS F. LYNE. One of the most essential considerations in the running of locomotives is, or ought to be, the internal lubrication of cylinders and slide valves, yet this subject is treated by many railroad companies with marked in-difference. What I mean by this is, that lubricants in the shape of tallow and oil are poured into the cylinders of locomotives in unreasonably large quantities, the greater part of which is blown out upon the first admission of steam and is wasted. Further-more it does great damage by being baked upon the inside of the exhaust nozzles, re-ducing their diameter and creating an im-mense back pressure. The netting in the stack is also clogged up more or less by this waste of oil and tallow. The time when lubrication in the cylinders is most neglected yet most needed is when the train is ascending heavy grades, and in starting a heavy train from stations. Any person can readily prove to his entire satis-faction the immense extra strain to which a locomotive is subjected in starting a heavy train, by placing himself by the side of the cylinder and watching the jerky and uncer- wide open. In this device boiler pressure was maintained in the pipes leading to the cylinders. It was at all times greater than the pressure within the steam chest, so that when once started and regulated the oil would be fed continuously to the cylinder throughout the entire trip. The cylinder head was removed at each end of the trip, when the surfaces of the cylinder were found to be covered with a thin film of oil. The quantity used during the entire trip was about six drops per minute. The lubricator here mentioned has been in use sufficiently long to prove beyond a doubt that it is reliable under all ordinary circumstances. It is found that the locomotive thus equip-ped handles very much easier and performs its work with much greater ease than before the continuous lubricator was applied. These facts naturally lead the reader to believe that there must also be a saving in coal, as well as a great reduction of the quantity of lubricant used. One pint of oil fed automatically to the cylinders has been made to answer for a run of about 130 miles, and there is reason to believe that in time a less quantity than this will be found suffi-cient. The advantages of an anti-friction device attached to the slide valves of locomotives are also becoming more and more appre- balanced valve due to the reduction in the friction, but the greatest advantages lie in an immense saving in the wear and tear of eccentric straps, links, pins, valves and seats. The steam that would be otherwise lost though leakage of the valves is saved. Furthermore, the quantity of lubricant used upon the parts is very much reduced. When once squared the valves remained so, whereas before the change was made they could hardly be kept square two days at a time. Another important consideration is to know the efficiency of the various classes of locomotive boilers. Heretofore it has been a very difficult matter to measure with accuracy the quantity of water fed to the boiler. It has generally been done by floats, or by weighing the tank before and after the trip, the difference being the quantity of water used. These methods involve too much trouble. I place a Worthington water-meter inside the tank and locate the recording mechanism on top, or place the meter in the coal box and connect the meter with the feed pipe. If pumps are used, the meter will record within a tenth of one per cent. the quantity of water fed to the boiler. When injectors are used, the waste must be returned through a hose to a receptacle in the tender, and the amount deducted from that indicated by the meter. The difference will be the quantity fed to the boiler. Then by weighing the coal, which is an easy matter, we can readily• ascertain the precise efficiency of the boiler. Almost every engineer has a different method of working his locomotive. The coal is not accurately weighed, neither is the quantity of water measured, therefore he does not know, nor has he any means of knowing, which is the most economical way to work his engine. By applying the meter to measure the water and weighing the coal, and working the engine differently each day, keeping careful and accurate records, it would readily appear which method offers the most advantages. These experiments would also suggest other advantages to be derived from the results obtained for any number of that class of engine.

professional papers and general discussions. Afternoon session, 2.30 P. NI. Reading of papers and discussion continued. In the evening the members are invited to a recep-tion given to the society by citizens of Cleve. land. Third Day—Thursday, June 14. The day will be devoted to excursions by special train among the prominent iron and steel works and the large manufactories of the city. Among the places to be visited are the Otis Iron and Steel Works, Cleveland City Forge and Iron Company, Cummer En-gine Company, Union Screw Company, Brush Electric Company, Warner & Swasey, Cleveland Malleable Iron Company, the extensive iron and steel works of the Cleve-land Rolling Mill Company, Eighteenth Ward, the Standard Oil Company, Central Furnaces of the Cleveland Rolling Mill Com-pany, the Iron Ore Docks, City Water Works, etc. The train schedule, with definite informa-tion as to the time and place of starting, etc., and with possible changes as to places to be visited, will be distributed at the time of the meeting. The evening session, 8 P. M Reading and discussion of papers and adjournment, un-less it shall prove necessary to order a session for the following day. Among the papers already in hand for the meeting are the following: The Marine Engines of the Lakes, with a Device for getting them off their Dead Cen-ters. By J. F. Holloway. History of the Winding and Pumping En-gines of the Anthracite Regions. Balancing Vertical Engines. The Bower-Barff Process. By W. F. Durfee. Standard in Pipe Fittings. By Wm. J. Baldwin. Ingot Cranes. By Gram Curtis. Spiral Springs; Compression and Tensile. By Oberlin Smith. Other equally interesting papers are prom-ised. It is hoped that the place selected for the meeting, together with the date named, will induce members, as far as possible, to bring ladies with them. Provision will be made for their entertainment while members are engaged in the meetings or are away on ex-cursions. COFFIN'S NEW AVERAGING INSTRUMENT. Lain movement of the valve stem. When a locomotive is drifting into a station the heat contained in the iron surfaces quickly evapo-rates the moisture remaining after steam is shut off. When the signal is given to start, the surfaces being dry and hot move upon each other with great difficulty. I have known rock arms to have been sprung under such circumstances, and in one instance a rock arm was twisted off owing to the great friction of the valve upon its seat with all the ports closed. An experiment to ascertain the power re-quired to move a valve under similar condi-tions may be tried by disconnecting the valve rod from the valve stem and attaching a lever, and weighing the amount of power applied to move the valve with the boiler pressure upon it. I am convinced from my own experience that the result will very much astonish those who try this experi-ment. Considerable difficulty has been expe-rienced in feeding a lubricant to locontotive cylinders continuously, owing to the great variations of pressure in the steam chest, and particularly when the throttle is closed, as it is is when the train is drifting or running down hill. I saw a device upon a locomo-tive the other day which fed a stated quantity of to the cylinders as well when steam was shut off as when the throttle was elated. Since the illustration of the Allen slide valve with the application of a balanc-ing device in the AMERICAN MACHINIST of Feb. 21, 1882, this combination has been ap-plied to a large number of locomotives upon different, railroads in this country where it has given very excellent results. I suggested the application of a pair of valves like those alluded to upon a lotomo-live running a fast passenger train. They were put to work and ran for a period of fourteen months without repairs, during which time the locomotive ran 44,168 miles. Before these valves were applied it was necessary to face the seats every six weeks, and the valves could never be kept tight. About seven tons of the load upon each valve was removed so that the power re-quired to move them was so much reduced that the engineer could move the reverse lever to any desired position with one hand. In starting out of a station, the latch being lowered upon the face of the quadrant, the driving wheels world frequently make two or three revolutions before the latch would drop into a notch, showing that there was very little power consumed in working the valves. An expert test of these valves against the ordinary D slide would perhaps show a small difference in favor of the balanced valve. There would necessarily be a better efficiency shown in favor of the his engine. By applying the meter to measure the water and weighing the coal, and working the engine differently each day, keeping careful and accurate records, it would readily appear which method oilers the most advantages. These experiments would also suggest other advantages to be derived from the results obtained for any number of that class of engine. Coffin's New Averaging Instrument. The accompanying engraving represents a modified and very much improved form of the Coffin Averaging Instrument which was described in the AMERICAN MACHINIST of Sept. 10, 1881. Since that time arrange-ments have been made with the Ashcroft Manufacturing Company, 111 Liberty street, New York, who are now manufacturing this instrument. In its present form the board is of a convenient form to fit in the till of an indicator box, while the instru-ment itself is contained in a neat velvet-lined morocco case for the pocket. The improvements consist in modifying the construction of the sliding clamp K, making the instrument of a better and more convenient shape. The end that slides in the groove is weighted to prevent the pin from being lifted out of the groove. This weight is simply a nickel-plated brass ball placed upon top of the pin. To measure an indicator diagram by this instrument the card P, is placed under the clamps as shown, with the space between the clamps which are set to correspond with the ends of the diagram. Place the tracing point 0, at any Mace upon the line of the diagram. Turn the wheel so that the zero marks exactly coincide, then carefully trace the line of the diagram and stop at the precise point whence the tracing began. The reading upon the wheel will indicate the area of the diagram. Place the tracing point at the lowest line of the diagram at D, set the wheel at zero and move the tracing point up the edge of the clamp toward A, until the wheel indication is the same as the area of the diagram. This will give the mean width or height of the diagram, A, D, and measuring this distance with the scale of the spring will give the mean pressure of steam in the cylinder as represented by that diagram. It will be observed that this result is arrived at without the necessity of mental or other calculations of any kind. This instrument is made in two styles, one of which is furnished with and the other without a morocco case.

It is intended for a 12-ton steam hammer. The large block was cast in a mould occupying the position which it will eventually occupy after it has been slowly cooled, and has been canted over upon its proper base. The mixture used was about one-fourth No. 3 Gartsherrie pig iron and three-fourths scrap cast iron. Two cupolas were used in melting, each capable of melt-ing six tons of metal art hour. Up to the present time there has been no anvil block in Scotland weighing over 140 tons. Locomotive Notes. SPECIAL SKILL WANTED FOR CERTAIN MACHINE WORK. BY ANGUS SINCL AIR. There is a peculiar elasticity of resort among Western machinists in their methods of achieving work without good facilities for doing it. Carlyle, or some other abstruse philosopher, asserts that the striking differ-ence between the savage and the civilized man arises from the ability of the latter to handle tools. The crowning triumph of the Western mechanic lies in his striking ability to perform work creditably without tools. This is not the characteristic of all Western workmen, but it seems better developed there than any-where else. Poor machinists are common enough in the West, but they do not gener-ally pass muster as first-class men, for their shortcomings show out conspicuously where they are continually required to do work on their own judg-ment, without direction of gang-boss or foreman. Per-haps this is the reason why Western machinists, as a rule, are so persistently adverse to admitting that one machinist ism to those whose daily work it is to put them together, but when such things get out of shape hundreds of miles away from the makers, and have to be repaired without delay, the man who proves himself compe-tent to do the work is a valuable adjunct to a machine shop. For the repairing of intricate machines and tools, essentials of machine shops, whose workings are imperfectly understood even among good machinists, special knowledge and special skill are requisite. An air pump comes in that is working indifferently, is in-termittent in its action, and seems to pound the cylinder head. A machinist who can work as close as a mathematical instrument maker takes the pump apart, and can per-ceive nothing wrong. The pistons are all apparently in good order, the valves seem to be faultless, and the man can change nothing without the probability of doing more halm than good. Another man goes through the pump, and previous investigation and study of such machines give intelligent direction to his examination, and he quickly discovers that the trouble lies in the air valves having too much lift. Knowledge gave this man power. Knowledge and skill together have made him an expert in this particular line, and he is justly entitled to enhanced remu-neration over the ordinary machinist, quite as much as the professional services of an ac-complished oculist are fairly reckoned higher than those of an ordinary surgeon. In railroad shops there is a constantly growing demand for machinists capable of do- Griswold's SaW Tables and Embossing Press. Two of the accompanying engravings represent two sizes of saw tables, made by George M. Griswold, which are now being introduced by Sweetland & Co., New Haven, Ct. These tables are• intended for fine wood work of all descriptions. The frames are of cast iron, having a box or receptacle for catching the waste and sawdust. They are provided with various gauges and angle plates by means of which material may readily be cut to all desired angles. An elevating screw enables the operator to ad-just the table at various heights. The saw mandrels are of steel having capped points hardened and ground before the arbors are finished, which insures a perfect balance and true running. The boxes are of babbitt metal in which the mandrels run on the cupped points. Saws are of an ex-ceptionally fine quality, and are adapted for EMBOSSING PRESS. " This will be an additional inducement to lead master car-builders to Chicago, and it is, therefore, expected that there will be an unusually large attendance at the annual con-vention this year. " Representative members are requested to be prepared to report the number of cars owned by their companies at the date of the meeting." Value of the Art of Mechanical Drawing. We make the following extract from the annual report of Director W. H. Thorne, of the Franklin Institute Drawing School : " That the importance of some knowledge of the art of drawing is becoming more ap-preciated every year is 'evidenced by the annual increase in the number of students in this school. It is a promising sign, for there is no sphere in which the ability to express conceptions of beauty of form and design, or ideas of mechanical devices and con-structions, by means of lines drawn on paper, in such a manner as to accurately convey these conceptions to others, will not prove of great value. The boy who at-tempts to make a bird-box will save time, vexation and material if he is able to plan it on paper, altering the design until it suits his fancy, and arranging the details and method of construction before he commences the work. So, the millionaire who is about to have a mansion built, if he is able to un-derstand the architect's plans, can criticise, suggest alterations and devise conveniences which will place the stamp of his own individuality upon it and prove a source of just pride. To one engaged in a mechanical or industrial pur-suit, a knowledge of drawing is coming to be indispensable, and those who do not possess it will inevitably fall behind in the race. To quote from the recently published auto-biography of the eminent Scotch engineer, James Nas-myth : Mechanical drawing is the alphabet of the engin-eer. Without it the workman -show out conspicuously where they are continually required to do work on their own judg-ment, without direction of gang-boss or foreman. Per-haps this is the reason why Western machinists, as a rule, are so persistently adverse to admitting that one machinist can be better than another. The progress of applied me-chanics has a constant tenden-cy to develop special skill on the part of workmen, in put-ting complex machines to-gether, and in handling and repairing them after they are in operation. There are machines and tools in every-day use that require master touches of refined skill at the hands of the fitter, and the exer-cise of rare ingenuity and judgment must be displayed in detecting causes of derangement after the machines have been at work. Yet it is quite a hard matter to convince the average machinist that the man who, by thought, investigation and study, has pre-pared himself to perform the delicate and difficult portions of shop-work is rightfully entitled to superior consideration, in the form of higher pay, than the common work-man receives. Men who are otherwise sen-sible and considerate display no kind of lib-erality when such a case comes before them. All at once they become zealous for uni-formity. When it is applied to the details of machine construction, uniformity is in-tensely desirable, but the spirit which at-tempts to reduce men's ability to uniform mediocrity cannot be too strongly opposed. The work of railroad repair shops is ex-tremely varied, and the greater portion can be done satisfactorily by men who possess no exalted order of mechanical ability: But, on the other hand, special work arises which calls for the highest order of dexterity, be-sides unerring judgment and keen sagacity. A complicated machine stops working, and has to be repaired. A too] gets out of order, whose anatomy is a mystery to ninety-nine out of one hundred machinists. Air pumps, hy-draulic rams, pumps and jacks, steam ham-mers, pressure gauges, steam pumps, brake at-tachments, indicators, injectors, and kindred articles are simple enough in their mechan- No. 1 SAW TABLE. ing the intelligent skilled work that is becom-ing so plentiful about air brakes, injectors, gauges, hydraulic apparatus and other special machines. And there is likely to continue an increasing ratio between the demand and the supply until improved means are taken to encourage machinists to prepare themselves to do this kind of work. Master mechanics, as a rule, are not any too anxious to recognize and acknowledge the true value of the services of men whose work is sometimes almost priceless, and they will generally keep the pay of the super-skilled man at the mediocre. level so tong as they can do so. This dis-courages the ordinary run of men from trying to acquire special mechanical knowl-edge. But the leading obstacle, to the proper recognition of special mechanical ability, lies in the reluctance of the trade to acknowledge special merit. Dog-in-the-manger sentiment is overwhelmingly dominant within the craft. Till something is done to eradicate or suppress this feeling the best friends of machinists will have continued reason to regret the apathy and want of ambition among the in-dividuals themselves to excel in an important branch of their business. H. C. White, who has for some time past been in charge of the Westinghouse Machine Company's salesroom at Chicago, will shortly start for Arizona to superintend the erection of machinery built by the company, after which he will make, in their interest, an ex-tended trip through Oregon and Califor-nia.

The other engraving represents a small embossing press, also made by the above named concern. It is of very simple con-struction, the table being adjusted by means of a nut and lever as shown. The operating mechanism. consists simply of a cam and roller, which receive their motion from a lever. The table is 10" x 12". A circular issued by M. N. Forney, Secre-tary of the Master Car-Builders' Association, says: " The next annual convention of the Master Car-Builders' Association will be held in the Grand Pacific Hotel, Chicago, beginning at 10 o'clock Tuesday morning, June 12. " Messrs. B. K. Verbryck, of the Chicago, Rock Island and Pacific Railroad, Chicago, and W. Forsyth, of the Chicago, Burlington and Quincy Railroad, Aurora, Ill., are the Committee of Arrangements, and should be addressed concerning hotel accommodations. " Members are requested to send ques-tions for discussion during the meetings to the Secretary before the above date. "A meetii/g for the revision of the rules governing the condition of and repairs to freight cars offered for interchange of traffic will be held at 4 u. M. on Wednesday, June 13, at the Grand Pacific Hotel. " The Exposition of Railway Appliances will be open in Chicago from the 24th of May • to the 23d of June. and those who do not possess it will inevitably fall behind in the race. To quote from the recently published auto-biography of the eminent Scotch engineer, James Nas-myth : Mechanical drawing is the alphabet of the engin-eer. Without it the workman is merely a hand ; with it he indicates the possession of a head.' It is of more or less importance in all pursuits, and that this is understood is shown by the number and the vocations of the students in our school. " The number of students this year amounted to 402, of whom 210 at-tended the winter term and 192 the spring term. In each term the school was divided into sev-en classes, with an instructor for each class, and instruction was given four evenings in the week, instead of two, as heretofore, on account of limited accommodations. The progress made has been very satisfactory." Milling Metals, FROM A PAPER READ BY W. FORD SMITH, BEFORE THE INSTITUTE OF MECHANICAL ENGINEERS, ENGLAND. There is a risk of fracture in making large milling cutters out of one solid cast steel blank, the principal difficulty being in the tempering. In practice it is found that if they are required of larger diameter than about 8 inches they are better made of wrought iron or mild steel discs, with hardened cast-steel teeth, so securely fitted into them that they do not require to be re-moved. The cutting edges can then be re-sharpened in their own places, as in the case of the ordinary milling cutters ; thus insuring that each shall have the same angle of cutting and clearance, run perfectly con-centric, and therefore do a maximum amount of cutting in a given time. It must, how-ever, be borne in mind that the smaller the diameter of the milling-cutter, the better finish it will produce ; and cutters of large diameters should only be used to reach into depths where one of smaller diameter could not. Again, the smaller the cutter the less

JUNE 2, 1883 AMERICAN MACITINIST page 5 does it cost to make and maintain. The writer has not had an opportunity of actually testing the relative amounts of engine power required for driving milling machines ; but as far as he can judge from ordinary prac-tice in doing ordinary work, he has not per-ceived that any more power is required to remove a given weight of shavings than that required for a lathe, planing machine, or shaping machine with efficient cutting tools in all cases. The cutting speed which can be employed in milling, is much greater than that which can be used in any of the ordinary operations of turning in the lathe, or of planing, shaping, or slotting. A milling-cutter, with a plentiful supply of oil, or soap and water, can be run at from 80 feet to 100 feet per minute when cutting wrought iron. The same metal can only be turned in a lathe, with a tool-holder having a good cutter, at the rate of 33 feet per minute, or at about one-third the speed in milling. Again, a milling cutter will cut cast-steel at the rate of 25 to 30 feet per minute. The increased cutting speed is due to the fact that a milling-cutter, having some thirty cutting points, has rarely more than three of these cutting at the same time. Each cut-ting point therefore is only in contact with the metal during one-tenth of each revolu-tion. Thus, if we suppose it is cutting for one second, it is out of contact, and there-fore cooling, for the succeeding ten seconds, before it has made a complete revolution and commences to cut again. On the other hand a turning tool while cutting is con-stantly in contact with the metal ; and there is no time for it to cool down and lose the heat imparted to it by the cutting. Hence, if the cutting speed exceeds 30 feet per minute, so much heat will be produced that the temper will be withdrawn from the tool. The same difficulty to a great extent applies to the cutting tools in planing, shaping, and slotting machines. The speed of cutting is governed also by the thickness of the shav-ing, and by the hardness and tenacity of the metal which is being cut ; for instance, in cutting mild steel, with a traverse of 4 inch per revolution of stroke, with a shaving about inch thick, the speed of cutting must be reduced to about 8 feet per minute. A good average cutting speed for wrought or placed on a slide in front of the tool carriage, so that it can be pushed back out of the way when not in use. When in use it is drawn on the slide against a stop, and secured by turning a thumb screw . This stop is ad-justable longitudinally, and the spindle frame is adjustable vertically, by being bolted to a wedge, so that the centering spindle can be brought at any time to correspond with the center of the main spindle, and rigidly clamped in place. The centering attach-ment is especially advantageous for shafting, or for heavy pieces, as they can be centered without rehandling. The weight of this machine is 1,900 lbs. Boiler Inspection and Management. From an account of the proceedings at the recent annual meeting of the Manchester Steam Users' Association we take the follow-ing notes: The chairman said that the association had. now more members, more boilers enrolled, a larger revenue, a larger reserve fund, and had made during the past year a greater number of boiler examinations, than at any time since its foundation in the year 1854. It strictly maintained its fundamental principle of making an annual entire " examination of every boiler, that is to say, an examination of the boilers inside and outside when at rest and prepared for the purpose. Without such examination no boiler was guaranteed, and no member who would not afford an opportunity for this was permitted to partici- crowns. The furnace crowns had been bared and brisk fires allowed to burn, until the plates were sufficiently hot to freely melt a lead plate and other lead strips laid on the top of the furnaces. The plate and strips were loosely attached so that there was a film of superheated steam between them and the iron, and as they were rapidly melted the furnace crowns must have been much hotter than the melting point of lead, !f not actually red-hot. Yet when water was sud-denly thrown upon the furnaces, so far from there being an enormous quantity of steam suddenly' generated, and the boiler rent in pieces according to the generally received opinion, there was no explosion, no rent, no collapse, and no movement of the boiler, while the pressure gauges were scarcely affected. The question was forcing itself upon steam users as to the material of which boilers should be constructed, whether of iron or steel. The term " steel suggested to the popular mind the idea of something hard and brittle, as for instance, a file, chisel, or other cutting tool. But there was steel and steel, one of the character just mentioned, and the other so mild as to bring it within the range of boiler construction, but possessing also other qualities which iron as a rule did not, notably homo-geneousness. That quality was now leading to its use for furnaces, as it was not liable, like iron, to laminate. Lengthened ex perience seemed to show that steel, if care-fully made, would gradually take the place 1111111111,11,1,, was the fault of the boiler owner, and not of the boiler attendant, and the remedy was an examination of the boilers, and not of the stokers, as a bill before Parliament requires, as a means to prevent boiler explosions.

to the cutting tools in planing, shaping, and slotting machines. The speed of cutting is governed also by the thickness of the shav-ing, and by the hardness and tenacity of the metal which is being cut ; for instance, in cutting mild steel, with a traverse of inch per revolution of stroke, with a shaving about inch thick, the speed of cutting must be reduced to about 8 feet per minute. A good average cutting speed for wrought or cast iron is 20 feet per minute, whether for the lathe, planing, shaping, or slotting ma-chine. Improved Cutting-Off Machine. The cutting-off machine illustrated with this is made by Hurlbut & Rogers, South Sudbury, Mass. It is designed for cutting off stock from 1" to 41-" diameter, and when desired is provided with a centering attach-ment for centering the pieces. As will be seen, two cutting tools are used with this machine, the tool blocks being connect-ed with a right and left hand screw. It is claimed that this is an advantage, in not only that two tools will cut faster than one, but that the pressure of one tool being diametric-ally opposed to that. of the other, the strain and leverage on chucks and bearings is re-moved or neutralized. The ease and rapidity with which the tools cut are also increased by grinding one of them V-shaped and the other square across. By this means the V tool removes the stock from the center of the cut and the plain-ended tool from the corners, thus dividing the work and strain between two tools, instead of throwing it all on one. The feed screw is 7 threads to the inch, and the worm gear has 41 teeth, and it is guaranteed that in ordinary stock a feed of 4 revolutions of worm to one of the spindle can be maintained. The cone pulley has four steps for 31" belt, the largest step being 14" diameter. The gears are cut from solid metal. The countershaft is arranged with friction clutch and two changes of speed, giving to the spindle of the machine eight changes. The feed has automatic throw-off. Each machine is furnished with two " Slate " cutting-off tools. The centering attachment is arranged to run from a separate countershaft. It is iii III IIII II hill 111111111111111111111111111111111111111111111111111111111111111111111111111111......,,,,,,, 111111111111111111111111111111111,111,11 CUTTING-OFF MACHINE. pate in the privilege of the pecuniary guar-antee. By strictly adhering to that principle the association was able once more to report that no explosion had arisen from any boiler under its charge during the past year, while it might be added that no life had been lost by any guaranteed boiler since the institution of the guarantee system in the year 1865, although during that period there had occurred, outside its ranks, as many as 791 explosions, killing 1,057 persons. To the association belonged the distinction of being the first public body to establish on a practical working basis the system of inde-pendent periodical inspection, and also of being the first to procure a legislative enact-ment for preventing steam boiler explosions on land. The Boiler Explosions Act, 1882, while it was in no way unduly hard upon the steam boiler user, was calculated to insure a more satisfactory inquiry as to the causes of steam boiler explosions, and thus to save life. No careful steam user could possibly object to the act. It did not in any way curtail his liberty, but left him absolutely free as to the choice of means, only holding him responsi-ble for results. Boiler owners were more indebted to the Manchester Steam Users' As= sociation for its attention to steam boiler legislation than they were aware. It had protected them from measures they would not by any means have relished. A series of experiments was now being tried upon the Lancashire boiler to ascertain the effect of injecting cold water upon over-heated, if not actually red-hot, fnrnace of iron in the construction of boilers, espe-cially if regard were had to the fact that ductility was of more importance than high tensile strength. The _question of smoke prevention, and the relative merits of mechanical and hand-firing, had been carefully considered by the Association, and the conclusions arrived at were that, as regarded economy, the two modes of firing gave practically the same re-sults. As many as fifty-five mechanical stokers had been removed from boilers under inspection. To prevent smoke by hand-firing, nothing out of the common was wanted, but only a reasonably fair draught, a reasonably fair boiler, regular firing, and the admission of a little air above the firebars to secure the combustion of the gases, The air might be admitted either at the firedoor or at the firebridge. It was a good plan to admit- the air at the firebridge in a constant stream through a number of openings having an aggregate area of about two square inches per square foot of fire-grate, and at the fire-door intermittently through openings having as nearly as may be an equal area. The subject of incrustation was very im-portant to the members. It was a good plan to introduce three pounds of soda ash per day to the boiler along with the feed water, but the soda should be good, and blowing out maintained. The investigations con-ducted by the Association for the last quarter of a century showed that the great majority of explosions were not due to the fault of the fireman, but to the fault of the boiler itself. Boilers were often worked on till worn out, and no thicker than an old sixpence, This be spent at Arlington or Bristol. Friday, June 8th.

Editor American Machinist : I have been using some of Mushet's special tool steel, and have discovered something about it that I do not like or understand. It is this: After the tool is forged and allowed to cool, I find that it is quite hard; but after it is subjected to grinding on the emery wheel, and has become hot several times, it also becomes too soft on the edge—in fact, so soft that it can be filed very easily. I would like some of your readers who have more experience in using this kind of steel than I have to speak and tell us the cause of this. There is also another little matter which has given me a great deal of trouble. It is the grinding of springs on an emery wheel I have often attempted to use the emery wheel in fitting case springs in watch cases, and whenever I have ground one on an emery wheel I have always had it break. No mat-ter how soft the spring was, it would always come out the same. To make more sure that grinding on the wheel was the cause of the breaking, I have fitted a spring to a case with a file, and had it work all right ; then have taken the spring out and ground off a little on the emery wheel where it Would not change the strength of the spring. I then put it back in the case, and it would break the first time the case was closed. Now, how is this to be accounted for ? 1 have also taken a dozen springs of good quality, and fitted them to a watch case by grinding on an emery wheel, and had every one in the dozen break the first time the lid was closed. The wheels I use are of two kinds, the tanite and the cellu-loid. Both of them, however, do the same thing. I run the wheels at a speed of about 4,000 revolutions a minute. The wheels are thick and 6" diameter. It may be that I am far behind the age in this matter, but if such be the case, I desire to know it. As it is 1 am perfectly at a loss to know why the

pressure, but adjusting their capacity and operation required time and patience. Later improvements have made the operation of testing comparatively a simple matter, but there is the same necessity for testing as ever. Important improvements made by Superin-tendent Richardson in the arrangements for testing have also simplified the matter. A separate room in the tower is devoted to test-ing valves. In this room is a special shell or drum upon which the valves are placed. This shell is three feet in diameter and eight feet in length. The longitudinal seam is made a butt-joint, with covering plates outside and inside, the rivets being arranged to get the greatest strength practi-cable with this joint. The heads are stayed by rods, extending from head to head, secured by nuts at each end. These rods have col-lars, one near each end, which are faced true. The heads are put in with the flanges outside. A copper liner completely covers the inside surface of each head, extending out over the flanges. Against these copper liners the collars of the stay rods make steam-tight joints. The heads were drawn into place, and nuts on stay rods screwed up hard. Then the holes for riveting heads to .shells were drilled and reamed, leaving no chance for disturbing local strains. It will be understood that there is no fire near this shell, but tha there is sometimes occasion to place it under high pressure. In use, this boiler is partly filled with water; then steam is admitted from either one of two special boilers, situated in the boiler room. By peculiar arrrangements the steam mingles with the water, heating it to a temperature due the pressure of the steam admitted, making steam in this shell precisely as if it were a boiler subjected to furnace heat, only more rapidly. Means are provided for se-curing rapid circulation of the water at all times. It is evident that the capacity of this shell for supplying steam may be made greater or less by graduating the flow of steam to it; also that the water in the shell is an additional heat reservoir, and that the pressure in the boiler supplying steam may be to any extent consistent with safety higher than the pressure in the testing shell, or the pressure at which the valve is to be tested. illy, those moans a comparatively small shell i H 11111(10 ample for testing the largest val yes made ; and this quality of
after being graduated they are tested once more and ifound right passed as correct. On this floor is an apartment where, in drawers suitably marked, the various small parts of the different gauges, which, of course, are made in large quantities, are kept ready for assembling. Finished gauges and indica-tors are also kept in stock in this room. Each separate room, or department has its own tool room, and necessary stock room ; also wash room and all needed sanitary con-veniences of the most approved kind, those for each floor being located in a room in the tower against that floor. The floors consist of 31 inch spruce with grooves and tongue pieces, upon which are laid 1-,} inch pine to break joints ; between these are two thicknesses of specially prepared roofing paper. This is for the purpose of making the floors both dust and water proof. All the rooms are heated by a system of overhead steam pipes, so arranged as to be used in sections or entire. This system seems to work very satisfactory, and appar-ently economically. In the rear of the main building is the brass foundry, a brick building 100x60 feet, with a monitor roof. There are ten furnaces in the foundry, which with the large floor and bench space gives a capacity more than

Moulding Pulleys.
BY ROBERT E. MASTERS.
In the previous articles on this subject I have been writing altogether on pulleys with arms in them, but there is another class called " web pulleys " to which we will have to pay a little attention; some firms prefer this style in smaller pulleys. I know one of the largest lumber and saw will concerns in the United States that use nothing but web pulleys of the heaviest class under 40" diam-eter, yet there are comparatively few web pulley patterns to be found in any foundry. Between a set of arm pulley patterns in halves and a set of band patterns, almost any kind of a web pulley can be made ; often orders for this class of pulleys are filled by cutting the sand out in the mould between the arms of the half pulley patterns ; this is an easy and quick way of making a web pulley. If however among the pulley patterns that are in halves one cannot be found of the right diam-eter, thickness of rim, etc., the plain ring or band patterns are then resorted to. Above is illustrated the moulding of a web pulley 36" diameter, 16" face from a ring pattern, 6" face, 1" thick, web to be 1" thick, The pulley ring is leveled up on the floor, rammed up in the cheek A and drawn up 2r; this allows the 1" web to be all in the drag, and brings it in the center of the pulley, a piece of board out in length to fit the inside diameter of the pulley across the center and 4" wide, shown in plan and section B B, with a hole centered in it, for the opens with bright prospects foes heavy de-mand and higher prices in 511 kinds of rail-way material. Even in the matter of locomo-tive engines and passenger and freight cars, contracts cannot be placed now within five or ten per cent, of the prices at which they could have been placed three months ago. A num-ber of moderate locomotive orders have been placed during the past 30 days, and we learn that several companies are contracting for ad-ditional locomotive capacity. The makers of the best approved engines are taking advan-tage of the present demand to widen their margins slightly, and in so doing are follow-ing the natural course of things."
ample. The core oven is fitted with revolving table and shelves. At present a blacksmith's forge and a tempering furnace, also a small engine for driving a fan are located in the foundry. These will be removed as soon as a blacksmith shop, which will be begun early in the spring, is completed. The smithing is now done at the company's shop in Lynn. The engine room is situated immediately in the rear of the main building, and as near cen-trally as to length as practicable; directly back of this is the boiler room. Power is furnished by a 65 horse-power Westinghouse engine, run-ning 315 revolutions per minute. The belt from engine is direct to an enlarged section of the line shaft in the lower room of the main building, the lines in the other rooms being driven by belting directly up. The driving and driven pulley on each use is wide faced for both belts. These pulleys arc loose on their shafts, except as they are locked by friction clutches. Throwing out the clutch in either room will stop the line in that room, the pulley running loose and driving the lines is the other rooms. There is also in the engine room a Knowles automatic feed pump and receiver for return ing the water of condensation from the heat-ing pipes to the boiler; this was described in our issue of April 3, 1886. A Knowles steam fire pump and a Goubert feed-water heater form part of the engine room equipment. A Babcox & Wilcox water-tube boiler, in the boiler room, furnishes steam for the en-gine and also for heating when the exhaust steam is not sufficient. Two boilers for use in testing safety valves, one a Whittier steel

hubs is bedded in the sand with the lower hub and filled in with sand flush with the board and the rim and a parting made. Before the cope is put on the bars are cut so that the rim can be drawn up into the cope when ramming it up the same as it is drawn in the drag, securing it good with gaggers at C 0, and having the nails D D in the cope extend out close to the pattern all around. After the pulley is drawn up to the right depth of face, four risers E 1' are set on top of the rim equal distances apart and the rest of the cope rammed up. The pattern is not lifted off with the cope for the reason that the draw-holes are at the top edge. After the risers E E have been taken out, four wrought-iron bars are nicked with a file or marked with a piece of chalk (if the chalk has not been " banished from the shop " ) the depth of the cope ; these bars are put into the risers, and the rim gently rapped back until it is even with the cheek, as shown ; the rods are then taken out and the cope lifted off. Before the ring pattern is drawn, the board B is taken out and the sand between the edge of the board and the inside of the pulley rim cut away from the rest of the web ; the pat-tern is drawn out of the mould and the mould finished up. The board B is a cheaper and easier way to make the web center than to make the whole circle for the web. This requires a great deal of work in the pattern shop, if you intend to keep it and not have it spring or warp out of shape. If thought best, this pulley can be made on the same plan all in the floor by having the bars extend below the cope the depth that it is to be drawn up above the web. The Railway Review says : ' The year opens with bright prospects for a la y de-mand and higher prices in all kinds of rail-way material. Even in the matter of locomo-tive engines and passenger and freight cars, contracts cannot be placed now within five or ten per cent. of the prices at which they could have been placed three months ago. A num-ber of moderate locomotive orders have been placed during the past 30 days, and we learn that several companies are contracting for ad-ditional locomotive capacity. The makers of the best approved engines are taking advan-tage of the present demand to widen their

Se-curing rapid circulatios of the water at all theses.
It is evident that the capacity of this shell for supplying steam may be made greater or less by graduating the flow of steam to it; also that the water in the shell is an additional heat reservoir, and that the pressure in the boiler supplying steam may be to any extent consistent with safety higher than the pressure in the testing shell, or the pressure at which the valve is to be tested. By these means a comparatively small shell is made ample for testing the largest valves made ; and this quality of capacity is absolutely essential to the correct testing of large valves. The third floor of the main building is called the machine shop. This is a clear space of 200x45 feet, the floor overhead being supported bv rods from the trussed roof. Here the more distinctively machine shop work for the various departments except that of safety valves is done. The " Tabor " indicator is also made in this room. There is in this room convenient for use a small steam drum for testing indicator springs. It is so ar-ranged that the pressure to which the springs are subjected can be suddenly let on and released, simulating the action when the in-dicator is in actual use ; the pressure can also be varied for scaling the springs. The "gouge coos" is in the fourth story. Here the gauges for all kinds of fluid pressure are assembled, and most of the work of man-ufacturing gauges done. The floor of this room is unobstructed except by the iron rods from the roof. Before the springs, of seamless drawn tubes, are put in place they are tested under steam pressure. While it is not intended, in use, that steam shall come in contact with the spring, it is sometimes carelessly permitted to do so. This will fre-quently give the spring a slight " set." To test the springs otherwise and to give them this set," which will do no harm before adjustment, they are submitted to steam pres-sure. After the working parts of a gauge are assembled they go to the workman who marks the dials for graduating, and who is provided with separate facilities for testing for vacuum, for steam or ordinary fluid pres-sure and for the highest requirements of hydraulic pressure. The springs are then submitted to a cold test and the dials marked. After being marked, presumably right, they are again tested for verification, and finally

Professor Kennedy, of England,
recently read a paper before the Institution of civil Engineers on " The Use and Equipment of Engineering Laboratories." He believed that it was essential for a young engineer to get his training in the workshop, but thought there was plenty of room for practical train-ing that fell within the scope of a scientific institution; this should supplement and Com-plete workshop experience without overlap-ping it. He enumerated the following sub-jects for investigation as being amongst the most important Elasticity and the strength of materials; the economy, efficiency and gen-eral working of pi ime movers, especially of the steam engine and boiler; friction; the accuracy of the apparatus commonly used for experimentation, such as springs, indicators, dynamometers, and gauges of various hinds; the discharge over weirs and through orifices, and hydraulic experiments in general; the theory of structures ; the form and efficiency of cutting -tools ; the efficiency of machines ; especially of machine tools, and of tsasuuoiu.l sion gearing ; the action and efficiency o pumps and valves ; the resistance of vessel and of propellers, and experiments coniaecte with both.

When boilers made from iron
are spoke_i of it is understood that their worth is largely dependent upon the quality of iron used. But it is not so generally understood that there is quite as such difference in the quality of steel as of iron plates. Specifica-tions for steel boilers should cover the quality even more carefully than for boilers wade of iron. Be one would expect a good iron boiler made of tank iron, yet this would be quite as reasonable as to expect a good steel boiler made from cheap material.

boiler and the other a Babcox & Wilcox water-tube
are situated in the boiler room. Both the boiler and engine room are ex-cellently well provided with light; in fact there are no dark rooms or corners in any part of the entire building, the whole being exceptionally well lighted. In the upper room of the tower there are two water tanks, one having a capacity of 8,000 and the other of 2,000 gallons. The larger of these tanks overflows into the smaller one, so the large one is under any circumstances always full of water for fire purposes. When the water will not flow to the large tank from the water service it is supplied by the fire pump. To the stand pipe connected with this tank hose is at-tached in each room, all ready for instant use. The fire pump will also supply water to this stand pipe, a check valve near the tank preventing the water from going there. Altogether these shops are excellently well arranged, and provided with all modern con-veniences both for the workmen and for expediting work. The rooms are high, well ventilated, and cheerful. The company have 3iow in contemplation the erection of a separate building for offices, etc., thereby giving the safety-valve depart-ment more room, of which the need is already felt.

LETTERS FROM PRACTICAL MEN.
Difficulties in Pumping Water. Editor American _Machinist :
Noticing an answer in a recent issue of your paper to a query in regard to pumping water by suction through a long pipe, I would submit the following, if it is worth anything, to the readers of your paper. We recently attempted to draw a small stream of water 800 feet through a two-inch pipe containing four elbows, with a good Knowles pump. The rise was about 16 or 18 feet, and was about 10 feet in a distance of 30 at the commencement. The pipe was laid carefully and was about two-thirds of the way under water, and was the rest of the way buried in damp ground, so we did not be-lieve that it leaked. A good foot valve was placed at the further end. When we started it had a tendency to pump air which it never got over. The pump had a small cock at the foot of the air chamber, and we were obliged to leave this slightly open so as to let the air out, or the chamber would fill until the valves, which were placed high in this style of pump would be out of water, so to speak. I have thought of the matter considerably, and have often wondered if the water which flowed on account of removal of pressure by couplings and elb ws was not relieved of a portion of the air which it naturally contained, and which did not again mingle with it in the short time in which it was in the discharging chamber of the pump. The pump, if it happened to move a little faster than the water would flow into it, would upon revers-ing, strike the inflowing water with a con-siderable jar, which battered the rubber valves and made them leak, and which was aggravated when the air chamber was full enough of air to come down as far as the upper valves. The pump also worked better though a little harder when pumping against a boiler pressure than when pumping into the atmosphere, which was probably due to increased pressure upon the valves holding them down. Now I would like to have the opinion of some one else in regard to my ideas as to the air in the water. Did the pipe actually leak, or does my experience differ from that of others who have tried a similar experiment ? If it did not leak I would suggest that others who eontemnlate such a move he very care-

HEAT OF COAL
to give 10.33 ; while mixed with anthracite dust it gave 10.12. Other kinds of coal gave as follows : Rey-noldsville coal, a gas coal which made so much gas the furnace could not manage it, 9.11 ; George's Creek Cumberland, 10.84; Pocahontas, 10.70 ; Elk Garden Cumberland, 10.46. These tests were made with a 50 horse-power Harrison boiler, and about 12 pounds of coal were burned per square foot of grate which had slightly over 50 per cent air space. Each test was continued two days under actual working conditions, and included coal for banking fires, etc. Difference between flue gas and boiler room about 380°. Not knowing the heating value of the different coals, I am uncertain how near the full value these results are. In one table the value of anthracite coal, or combustible is put at 14,500 heat units ; Cumberland, 15,370 ; and coking bituminous, 15,837. W. E. CRANE.

Core-Box and Core Making. Editor American Machinist : In a foundry of which I had charge they used thousands of bevel gears and small pulleys, all using ;" cores. The cores kept a large boy busy about all the time ; they were made in a wooden box, which in a short time became so worn that it was impossible to get a good core. I had an iron box made like the accompanying sketch. I then had all the prints on patterns using that size core altered so as to use all one length, thus saving the made up the bottom and put on the top section, stopped up the joint between them and put in the fire. I got the blast from the pipe at the blacksmith's fire. The cupola was made, the iron melted and the piece moulded and poured before noon. I used that cupola several times afterwards, having taken as much as 1200 or 1500 pounds of iron out of it. THOMAS WATHEY.

A Small Cupola.

Editor American Machinist : Being interested in the accounts of small cupolas, published in your paper, we con-cluded to try one. Six months or more ago we built one 19" inside diameter, and have been running it steadily ever since. Average work is 1 lb. coal to 10 of iron. The largest single piece poured was 1,470 lbs. The largest total of clean castings from one heat, 4,750 lbs. Have just poured a bed plate 1,300 lbs. Iron was melted in about 1 hour's. All scrap iron used. Fuel, hard coal, grate size. Fan 24" diameter ; 1,800 revolutions. C. T. A Presentation oil Retirement.

We recently noticed that the Cuyahoga Works, of Cleveland, 0.,
had sold out to the Cleveland Shipbuilding Company. J. F. Holloway, President, and Thomas McClure, Secretary of the old works, retired from active business relations with the concern. The occasion was observed by the employes of the works by presenting a fine bust of Sir

Quick Setting of an Engine.
A few years since a 24"x48" engine was to be put in the works of the Union Metallic Car-tridge Company, at Bridgeport, Conn., to replace the engine then in use. To do this the old engine and foundation must be re-moved, a new foundation built and the new engine placed. Mr. W. F. Durfee undertook the job, and in five days and eight hours from stopping the balance wheel of the new engine was turning over. The foundation, except at and near the top, was made of rub-ble. These stones were roughly placed to-gether and marked before stopping the old. engine. A templet was also made with cen-ter line and bolt holes accurately marked. In the centers eye-screws were placed, and the templet made fast overhead, so that lines let fall from these eye-screws indicated corre-sponding positions on the foundation. We recently saw this engine in operation, and the superintendent of the Works, Mr. A. C. Hobbs, called attention to the fact that he had never been able to detect the least parti-cle of movement of cylinder or pillow block on the foundation. This engine carries two 36-inch belts from the fly-wheel pulley, 15 feet diameter, to two 7 foot pulleys on the jack shaft. They drive as evenly and smoothly as if but one belt was used.

Quick Mechanical Work.
When the steamship Alaska arrived in this port it was discovered that the piston was cracked ; it was also evident that the return trip to Europe could not be made with the piston in this condition. The piston was 100 inches in diameter and 16 inches deep. On Tuesday evening, 18th of January, an order for a new piston was sent to the Delamater Iron Works of this city. At 7 o'clock of the same evening men from the Delamater Iron Works took measurements of the piston on board of the ship. At 7 o'clock of the following morning the sweeps for the piston were sent to the foundry, and it was cast on Friday evening at 5 o'clock. During Satur-day the casting was allowed to cool. On Sunday morning at 7 o'clock the piston was placed in the boring mill, and Monday evening at 6.30 o'clock it was turned, drilled, completely and successfully finished.

aggravated when the air chamber was full enough of air to come down as far as the upper valves. The pump also worked better though a little harder when pumping against a boiler pressure than when pumping into the atmosphere, which was probably due to increased pressure upon the valves holding them down. Now I would like to have the opinion of some one else in regard to my ideas as to the air in the water. Did the pipe actually leak, or does my experience differ from that of others who have tried a similar experiment ? If it did not leak I would suggest that others who contemplate such a move be very care-ful to have ample room in the suction pipe to avoid friction, and also select the best pumps, and that they should be so made that the dis-charge would be above the valves and not below them. E. D. DAVIS. Minneapolis, Minn. .

Heat Value of Coals. .
Editor American Machinist: Your suggestion that some simple means for determining the heat value of different fuels if carried out would be invaluable, as in practice they give widely varying results. For instance it has been the practice of the writer to test various coals that were offered, and from that test determine whether to pur-chase that grade or not. In getting at the value all have been determined from 212' feed to pressure of atmosphere per pound coal, as the ash had to be paid for at the same price. Quoting from my note book one pound anthracite egg size evaporated 9.15 pound water, ash 13.5 per cent. Webster coal, fire about 6" thick and spread even and but little fired at a time 9.81 pounds water, 5.68 per cent. ash. " From and at 212° " per pound combustible would make the egg coal 10.48 and Webster 10.40. I then tried firing the Webster so as to coke it as much as possible, in this way : The fire was carried 10 to 12 inches thick, and one side of furnace was allowed to burn bright while the other was covered and allowed to coke. When the side that was burning needed re-plenishing cover it over medium heavy and break up the other or the coke. This method brought the evaporation up to 10.63 per pound coal, and other tests showed about the same difference between the two ways of managing. Another cargo of same coal was only able Fig. 1

Fig. 1 shows elevation ; dotted lines show some of the various styles of cores that can be made. Fig. '2 is a plan and Fig. 3 a section through A B. Fig. 4 is a plate for drying thee cores. The flange on end should be half the diameter of core. Fig. 5 is a clamp for the ends of the box while ramming up the cores, The line D in sectional view shows vent-hole through bottom of box. After the cores are all rammed up, the box is turned over, and they are vented from the bottom. .

A Small Cupola. Editor American, Machinist : Some time since I read in the AMERICAN MACHINIST an account of melting iron in a ladle. I thought I would try it. There had been a failure of another man the day before, but I thought that by a little addition I could succeed. The effort was a grand failure, not as regards melting the iron—that was melted, but when I came to pouring it had set in the bottom of the ladle. One day after that a break down job came in, wanted that day. I was not going to cast that day, so I thought I would try another scheme. I found two sections of an old smoke stack, each about 2 feet long by 18 inches diameter. I cut two holes, one for tapping out and the other for a tuyere. I shoveled some sand from front of cupola and mixed it into a mud and daubed up the sec-tions, placed a flask near the blacksmith forge, filled it up with rubbish and set one of the sections on it, with a piece of sheet iron through the front hole for a spout. I then .

for a new piston was sent to the Delamater Iron Works of this city. At 7 o'clock of the same evening men from the Delamater Iron Works took measurements of the piston on board of the ship. At 7 o'clock of the following morning the sweeps for the piston were sent to the foundry, and it was cast on Friday evening at 5 o'clock. During Satur-day the casting was allowed to cool. On Sunday morning at 7 o'clock the piston was placed in the boring mill, and Monday evening at 6.30 o'clock it was turned, drilled, completely and successfully finished. At 7 o'clock of the same evening the piston was in the cylinder with all the nuts screwed down, and the job was finished. On the following morning, Tuesday, 25th of January, at 5 o'clock the ship started for Europe with a new piston weighing 13,000 pounds. Considering the size and weight of piston, and also re-membering that no pattern for the same was on hand, it must be admitted that this piston was very quickly cast and finished. The energetic management of the Delamater Ii on Works deserve great credit for showing our English cousins what American workmen can do ; and we believe that this record cannot be beaten on the other side of the Atlantic. Previous to 1882 the cost of an engineer's license from the inspectors of steam vessels was from $5 to $10, according to grade. In 1882 it was reduced to 50 cents, and in 1886 the fee was abolished altogether. The Railway Age tabulates the railway mileage of 47 States and Territories on Jan-uary 1, 1887, and finds the total to be 137,500. Illinois stands at the head with 9,579 miles, and Rhode Island at the bottom with 400 miles. Iowa stands second with 7,907 mi s Pennsylvania third with 7,817, and New 'k fourth with 7,466 miles. .111111..- The Albany Journal says : " It is never safe to enclose an old greenback in a letter. * * If you will notice an old greenback it has a peculiar smell about it that can readily be perceived even if enclosed in a letter." With all deference to the sense of smelling lodged in the editorial sanctum of the Journal, we suggest that the Post Office clerk, or letter carrier, who could not tell without smelling whether a greenback, old or new, was enclosed in an ordinary letter must have a phenomenally poor sense of feeling. .

Walter Scott to the former, and a gold-headed cane to the latter. Thomas D. West, fore-man of the foundry (who remains in that position), made the presentation address, which was very appropriate. " I supposed," said Mr. Holloway, in reply, " when I made the speech to you which conveyed the information to you that the old Cuyahoga Steam Furnace Company was no more, it would be the last time that I should address you. This scene is in some respects the saddest of my life, and while the parting is attended with the keenest regret, I cannot but beb eve that the change will be of advantage to you all. In my past connection with you I have always tried to do what was right and to deal justly by both my men and their employers. If I have failed in this, it has been the fault of the head and not of the heart. Since I came among you, nearly a quarter of a century ago, the changes have been many, but I cannot speak of this. Many of you have grown to manhood in my em-ploy, and the thought as expressed by Mr. West, that I have been instrumental in making your lives pleasanter, is one of the pleasant thoughts of this hour. When the firm went out of existence, my only fear was that, perhaps, some of you would be de-prived of your situations ; but when I was assured by the new management that all the men would be retained, it brightened the pleasures of the new year. I don't know how I can thank you for this handsome present, but permit me to assure you that it will ever be cherished as a reminder of the kindly feeling that has always been shown me, and which I hope will continue." Mr. McClure thanked the men briefly for the cane, and said lie would ever think of the men and " old Cuyahoga." .

Multiple Drilling Machine.
The accompanying cut is a representation of a multiple drill having eight spindles, all entirely independent of one another as re-gards rotation or feed. All are provided with power feed having three changes, and so arranged that it can be made as fine or coarse as the user may desire by simply changing the relative sizes of a pair of change gears. All spindles are also provided with a quick return lever at the left of the spindles. This lever can be moved through the butt in which it is held, thus enabling the operator to vary its length and use it for light drilling or other work ; it is secured against slipping by a thumb-screw. The spindles are arranged in sets of four, each set being driven from a transverse shaft at the back of the machine that is provided with a four section cone of large diameter and beltface and back gears; this shaft imparts rotation to the spindle through a simple ( fficient and easily working friction coupling. Each spindle is accurately balanced by means of the link lever and weight shown at the top, and is so held in the quill that it is impossible for it to drop sud-denly, as the drill point begins to break through the metal at the bottom of a hole. The machine shown will drill without strain-ing a 2-inch hole out of solid steel and other metals proportionately. The makers, Prentice Bros., of Worcester, Mass., make their multiple drilling machines

with as many spindles as desired, with heads stationary or can be moved to any desired distance from center to center-8" ordinarily being the smallest distance, though they have built machines in which the spindles ap-proached to within 3 and 5 inches of one another. The feed can be made independent or not as desired, and the table either as shown in the cut or running the entire length of the machine. These machines are built of all sizes, corresponding to the single spindle machines of the same makers that range from 12" to 50" swing. The first of the style of multiple drills shown was built for the Silver & Deming Manufacturing Company, of Salem, 0., and used by them in the manufacture of pumps, and is in use at present and giving great satisfaction. The machine illustrated in the cut is at the works of McConway & Torley, Pittsburgh, Pa. The weight of this machine is eleven tons.

Notes from Wage-Earners. A reader in North Platte, Neb., writes : " Here in North Platte, machinists' wages run from $3.35 to $3.50 a day ; good blacksmiths, $3. 5 to $4.00 ; boiler makers, $3.50 to $3.85. Still there are drawbacks to this State. There is no use in au Eastern man coming out here on spec. The companies hire no new men. Sacramento, San Francisco and Denver are full of idle men. Many skilled workmen from the East have to take laborers' jobs. A correspondent in Newport, Ky., writes : " The demand for machinists, tool-makers,

ter, and as more care is taken in the distribu-tion of stresses. The stresses per square inch allowable in good practice on wrought iron, and the so-called mild steel has gradually increased until it has reached as high as 14,000 to 16,000 pounds for medium sections for quies-cent loads. For intermittent and suddenly applied loads the allowable stress decreases, running down to 6,000 or 8,000 pounds or lower, for loads which reverse in direction. Factors of safety have been called " factors of ignorance," but it would be hardly just to judge a designer's ignorance by the size of his factor of safety. The factor of safety varies not only for different materials, but also for the same ma-terials under different conditions. When the breakage of a part would do little damage, a lower factor is allowable than if its failure would be disastrous. When failure would be likely to involve loss of life, safety should be secured at any cost, as far as it is attainable. This is the prime requirement, a failure to meet which cancels all other merits, no matter how great. It is but a few weeks since the drum of an elevator in Boston crushed like paper under the coils of the hoisting cable the fall of the car seriously injuring three persons, two of whom have since died. The inscription on their tombstones should be " Murdered to save $5.00." There may be some excuse for the neglect to provide safety devices on hoisting machin-ery of this class, as there is so much doubt as to their effectiveness when most wanted,

but for the criminal recklessness of the eleva-tor manufacturer, who, for the sake of saving a few pounds of iron, will make so important a part of such a machine unsafe, there can be no excuse whatever, no matter how keen the competition. That many of the cheaper kinds of eleva-tors are dangerously weak is notorious to those engineers who have had occasion to ex-amine them. No safety device is likely to be of service when wanted, which is either complicated or likely to get out of order. They are never in use, except in case of accident, and not being used are abused, at least by neglect. Except on the higher class of passenger elevators the safety devices are never inspec-ted, and even when known to be out of order are seldom repaired. Neither are those likely to be effective which are designed to stop the car with a sudden jerk after it has dropped two or three feet, or which depend for their action on the slackening of the hoisting cable. Only those are reasonably safe which are put in operation by any acceleration of the speed of the car above a certain limit, from any cause whatever. The conditions of a " trial trip " are differ-ent from those obtaining in actual service in this as in many other classes of machinery ; and effectiveness at that time must not be accepted as proof of equal efficiency after ten years of neglect.

Consider the merits of a suggestion, not its source. For this reason a rotating shaft should be larger than a stationary stud or bar carrying the same transverse load. The laws governing the action of reversed and intermittent stresses are not perfectly known, but it may be assumed as sufficiently accurate for practical purposes, in the case of alternate loads, to take double the nominal load as the total on which to base calcula-tions. In high speed machinery account must be taken of the strains set up by the action-of heavy parts in motion. Do not assume that, because a pulley or gear is turned all over, it is balanced. Symmetry of form is not always an indica-tion of uniformity of material.

> ******************************************************** Suggestions in Machine Design. IV. BY A. J. SHAW.
Bearing, instead of being, as is too often the case, the weakest should be the stiffest part of the shaft many bearings give trouble by heating or cutting from this cause alone. Long bearings wear long. But increase of length beyond a certain limit is of little, if any, value, especially if the diameter be not increased at the same time. A bearing which deflects in its own length is of less value than a smaller one which preserves its form.

Nothing is gained by making bearings large, and then necking down at their ends so deeply that the angle of the shoulder is in-side the parabola forming the line of " uni-form strength." An engine lathe, from one of the best shops in the country, has a spindle the front bear-ing of which is 2 inches in diameter, but necked at either end for face-plate and hub of back gear to 14 inches. For a bearing of this diameter the neck should have been not less than 2+ inches, as a minimum, in order to develop the full strength of the spindle, or if the neck be assumed as correct the bearing should have been not over 2 inches, while inches in diameter would have answered every purpose. Sudden large reductions in diameters of shafts carrying transverse loads are elements of weakness ; not only are the strains concen-trated at the necks, but the tendency is to, and there is danger of, cutting below the line of uniform strength. That machine is best proportioned in which the stresses are most equally dis-tributed among all its parts. There is a constant tendency in modern de-signing, where equality of strength rather than stiffness is the end sought, toward the use of smaller nominal factors of safety, and this is allowable with no actual decrease in the safety of the completed structure, as we acquire a better knowledge of our materials as they become more homogeneous in charac- rsk

Offset levers and other parts subjected to a combined bending and torsional stress are best made of a section approaching the cylin-drical. When possible, the heaviest loads should be carried nearest the points of support. In a certain machine tool a cone feed-pul-ley carries on its hub a small pinion both running loose on a stud some six or seven inches long. The pinion is at the outer end of the stud, although there is no visible reason why it should not have been placed at the inner end, thus reducing the large bend-ing moment, which at present exists when carrying a heavy cut. Perhaps the designer first sketched it in that way, and did not care to take the trouble to change his drawings. Many indifferent arrangements go into the shop, and are in use, for this reason alone. Don't be afraid to make changes in your drawings before they go into the shop. It is better to make alterations yourself before, than to allow some one else the chance to sug-gest them after the design leaves your hands. Criticise your own work most severely even then you may be sure that after you have discovered all its faults, the first man who looks it over after you, will find another and suggest a change. Designers who do not criticise their own work, but see it only to admire, generally ad-vance in knowledge like a crab, sidewise. • Never prefer your own ideas to better ones of others, simply because your own are your own. Do not let your judgment of the work of another be influenced by the personality of the workman.

etc., does not seem to be equal to the supply. but an average man can always get $2.23 or $2.50 a day, i. e., I mean an average ma-chinist. A took-maker's wages depend upon the job he " strikes," I have known them to get $5.00 a day—on special work—and have known good men to work for $2.00 a day when hard up. All the shops seem to be run-ning full time so a man who has a job can make full time. There is no busy " hurry up " season with a corresponding dull season, I think the cost of living here is very mod-erate.

A correspondent in Lowell, Mass., writes : " In this city the wages vary from $1.25 to $2.00 per day. A tool-maker or expert on planer or some specialty may get $2.00 per day if he fights hard for it. I don't think that they pay more than $1.75 on any of the corporations to machinists. They (the ma-chinists) must feel proud. The laborers on the streets now get $2.00 per day in this same city. Sir Joseph Whitworth, the ckbrated English engineer and man.ufacturet of ma-chinery, died recently at the age • 84. He was born in Stockport, England, cquired his mechanical training at Manches , where his extensive works are now loc ed. As

early as 1851 his improvements in iron planers and other machine tools attracted considerable attention at the World's Fair in London. He was a commissioner to the World's Fair in New York in 1853. In 1854 he began to make breech-loading rifles and cannon, and his success in this line is well known. He was made a Baronet in 1869. He was a great advocate of standards in ma-chinery, and successfully introduced into England the Whitworth standard screw thread, with which our eaders are familiar. He was an author as well as an engineer, and has published several works on mechanics,

We have in our works and in constant use, about one hundred Milling Machines, and our experience with them has demonstrated that for manufacturing purposes where many duplicate pieces are required, that the best work is produced and the most econ-omical results obtained from machines that are con.- 1 pact and solid, so arranged that t he pieces operated upon can he quickly placed in position and quickly removed after the cut is taken. We have designed a line of Milling Machin es for manufacturing purposes, combining the above de-sirable qualities, of which the No. 3 Plain Milling Machine is a type, and by their use we have sound it practicable to produce from10 to 20 per cent. more work in a given time than we could possibly obtains from any other type of a milling machine on the same work. The Spindle is driven by a gear and pinion from a three-step cone with 3" belt. It has a vertical adjustment of 6". The Table is 9" wide, 27" long, and has-12" longi-tudinal and 4" transverse movement and is moved longitudinally 2" by one turn of the hand-wheel. Tlae Feed is automatic with three changes, stopping automatically at any required point. The Vise has jaws 6Y8" long, 1 7-16" deep, and will open 33/8", Counter-shaft has pulleys 10" diam. for 3" belt, and should run about 375 turns per minute • The Price includes vise, counter-shaft, wrenches, &c , delivered f. o. b. at Providence, It.

Buying-A M E R I C A N M A C H I N I S T-Section Vol. 56, No. 1
Cut Production Costs-With Modern Equipment.


LET'S START RIGHT NOW
to do those things necessary to bring conditions back to normal. We've faced business stag- nation long enough
now to know what it means; so /et's go- let's get started on the right track again. This business de- pression will last
just as long as the people of this co\untry sit back and wait for something to happen-we've got to make things
happen.
We can accomplish nothing by waiting for the other fellow to start something-the chances are he is sitting back
waiting for us. We've simply got to realize that it is up to everyone to do his share, and there never was a better
time than right now to start the "ball a'rolling."
Then there is another and probably a much more threaten- ing angle to the situation. The period of prosperity just
passed has witnessed a tremendous over-expansion in practically every industry, not only in this country, but
throughout the entire civilized world. `As a consequence, today, and likely for many years to come, the facilities for
production will be greater than the powers of absorption-which means the keenest kind of competition and the
weeding out of the less stable and less progressive concerns in each industry. Business houses today are fighting
for their very existence, and those who survive will be the ones that start now to reduce their costs and better
their methods, in order to meet the keenest competition on a fair basis. ~
How should we begin? Where should we start?


If every manufacturer in the metal working industry would start by putting his own house in order, by replacing his
old worn'-out tools with new and better machines, by weeding out bis obsolete equipment, and installing more
modern, more prohtable equipment in its place, the first thing you know, we would have better business, things
would begin to move again, and industry once more would "hit the trail" of progress. We, The American Tool Works
Company, have already started. Since Jan. 1921, we have weeded out of our own plant, eighty-three machines of
different kinds, and are now replacing them with the latest and most modern tools. By this we have provided
business for the foundries, orders for the steel mills, and work for a number of men-in other words, we have "gone
into action" in our own plant.
If you will do the same in yours, the other fellow the same in his, and so on, ad infinitum, this country would soon
forget that there was a business depression, a readjustment period or a deflation spasm. It is up to every one of us
to put our shoulder to the wheel, so let's go-a slang expression -yes-but chuck full of meaning and good advice.
