of the truck, as shown in Figs. 2 and 3, these serving to prevent shifting while the subse-quent operations are going on. Each succeeding section is made sufficient-ly smaller than the one next below it to go inside of it, the model having the sections composed of tubular corner pieces, though in practice angle-iron would be preferable, because space could be better utilized. The method of attaching the ropes by which the tower is raised will be understood .4,1 from an inspection of Fig. 4, where, sup-, i( posing t'imopes A A to be pulled down-wards by the operation of the windlass, they vill, of course, raise the section B B, to which the:- -are attached at the bottom, as shown; and this section acting upon rope C U raises the next upper section; rope C C being attached at one end to the section A- A, as shown, while the other ends are attached to the bottom of the next higher section, and so on up to the top, all the sections moving to-gether. Safety catches adapted to engage with notches formed in the corner pieces pre-vent the sections from coming down in case of the breakage of a rope, or by reason of any other accident short of a complete breakdown. At each corner of the truck are attached guy ropes which reach to the top, and are so arranged that they maintain an equal tension at all times, thus steadying the tower. The upper or supplementary ladder is in two parts, one of which slides within the other, so that it can be extended to any de-sired distance within its limits, and there are hooks placed at the end that are so arranged that upon striking anything—such as the side of a building—they are thrown into position to catch upon a window-sill or other projection, and support the extreme end. The cage is guided and kept in place by a light chain, which extends from the top to the bottom, passing through the cage, which is handled from the platform, and permits per-sons to be let down in almost absolute safety. Usually the top of the tower will be above the telegraph wires, but in case it is desired to work through them there is a means of cutting through them. The mechanism by which all this is ac-complished is simple; in fact, such mechan-ism as has been used for other purposes, and is known to be practicable.

MACHINIST AUGUST 25, 1892    Machine Shop Observations at Fitch-burg, Mass. 
PUTNAM MACHINE COMPANY. 
About the year 1836 J. & S. W. Putnam began the manufacture of machine tools for the market. These brothers started in busi-ness at Fitchburg some years previous to this date, all by themselves, as it were, in a little building on Water street, which building, we believe, has been demolished. Their work was principally in the way of doing repairs. Before long they called an apprentice to their assistance—Carter Vanderford—who remained in their employ and that of the company that grew up from their humble beginning, until his death, a year or two since. In 1830, as near as can be determined, the Putnam Brothers built, for their own use, the lathe which we

illustrate on page 5 as a relic, and as showing the state of 
did not begin the manufacture of machine tools for sale until about the year 1836. One of the first tools brought out, we believe, was a gear cutter, -11ich found much favor, some of those originally made being in successful use to day. The tools brought out by the Putnams found immediate favor; they were convenient in operation, neat in design, and of a finish then very popular, but which would, to-day, be considered rather too ornate. The " Putnam" tools found such ready sale that, in 1858 (the brothers had previously moved into larger shops) the present Putnam Ma-chine Company was organized. About this time the well known Putnam steam engine was brought out. This was claimed to be an infringement on existing patents, but the courts decided in favor of the Putnam Com-pany. Since then the company has done an extensive business in the manufacture of these engines, in addition to its business in 
the largest foundries in New England. In addition to these are other buildings, such as brass foundry, paint shop, pattern shop, tool room, storerooms, etc., etc. Besides these shops the company hag, sin,, the consolidation with the Putnam Tool Co., an additional shop on another street, 130x45 feet, three stories high, with a large base-ment and wing. This brief and incomplete reference to these works will give some idea of the ca-pacity for turning out tools and engines with which most of our readers in this and other countries are familiar. In a recent visit to the shops we found them very busy on heavy tools, and fairly busy on steam engine work. On light tools there was not so much activity. We noticed under construction a lathe for the Brooklyn Navy Yard. This lathe is 80 feet long be-tween centers, and 74" swing. It is a " dou-ble-header," that is, it has two heads and two foot-stocks ; it has three carriages. We shall not, at this time, attempt a description of any of the characteristic features of this lathe, as we expect soon to fully illustrate it. There was also under construction an 84" swing lathe, but not so long as the government lathe.       A noticeable feature of the Putnam works is the length of time that men remain in the employment of the company. This is partly due to the fact that it is a good place to work, and partly to the fact that the com-pany never discharges a faithful workman because of the inroads of advancing years. The writer had means of knowing some-thing of the shop force of this company thirty years ago, and was surprised in his recent visit to see so many of the " old hands" still at their posts. It is a practice—this retaining of elderly men—so opposed to that of the more customary practice of send-ing men adrift after getting the work of a few of their younger years, as to deserve this brief mention. There is little danger of strikes where such a spirit, with other senti-ments sure to accompany it, prevails. It was noticed that the management is alive to the necessity of devising new meth-ods of doing work that shall cheapen the cost of product without infringing on its ellaractiir am t ft..

world, to his family (if he has one), to him-self ? The answer is, nothing. He does not stay in a town long enough to buy himself a suit of clothes before the old fever takes its hold, and he imagines that he can do better elsewhere, so he leaves that place for another, and so on. Everywhere he will boast to our boys that he made $5 per day in New York, $6 -per day in Pittsburgh, and so on, thereby making them think that as he made such wages there, and is only getting $2 in their town, that they, too, could do better if they were to start " on the road," as he calls it. Now let's follow our young man, for it is lie that we are interested in. We will con-sider that he is a man of 20 years, that has only partly served his time, and is getting $1 per day. Going to a neighboring town be chances to get a job by representing himself to be a finished machinist, and is put to work at $2 per day, with the agreement that the wages will be raised as soon as he proves that he is worth more. I am sorry for him, but that day never came, for before the week was up lie had lost his place, simply because he got stuck on a simple job. But he got another place, and soon lost it. After awhile he got used to roving, lost all ambition to better himself, being contented to make a living some way or another, and at last we find him boasting about the high wages that he has command-ed, when $2 per day is the most he ever earned. Of course, there are good men who are compelled to wander around some times on account of slack times, etc , but when they do get a job they are pretty likely to hold it, and they will be the last ones to advise you to start " on the road." Well do I remember when the desire to " strike out " came over me. I wrote to the AMERICAN MACHINIST for advice, and was told to stay at home, which I did, and have lived to thank that kind editor for his ad-vice. As a parting word, ]et me ask every young man to work to the interest of his employer, thereby benefiting himself, for such thin us will be notieed 1)0 ►(►, g(► trtutildttg; and

possible from expansion. Why is it, we may ask, is there so little trouble with car axle bearings, comparatively speaking? Simply 

ENGINE BEARINGS. 
because they are " badly fitted " to the eye of the unlearned apprentice; they have end play and very little bearing surface, and are at best rough pieces of work, but they serve their purpose, and we all know that different classes of bearings will endure very different load intensities, according as the work through them varies in its application. The crank-pin carries a much higher unit stress than the crank-shaft, though not perhaps so much higher as it is often thought to do in the absence of any consideration as to the inertia of the piston-rod, crosshead, etc., and yet the velocity of rubbing is fairly high on a crank pin which has a big diameter, though it loses surface by its shortness. The poor, cheap engine seen by Bell Crank had at least a cap to its bearing which was de-prived of much of its power to cause a grip-ping action, and to such an extent is a better design than the more expensive Fig. 1 type. The same gripping action is characteristic of locomotive bearings, unless provision be made to prevent it. Bearing stresses are usually calculated at so much per projected area of bearing, this area being the length X diameter, but this does not mean that a bearing stress thus obtained, of say 130 pounds per square inch, is a proper figure for a crank-shaft. It does, however, tell us that a proper intensity of pressure per actual bearing is such that it should not exceed what the figure of 130 upon the whole pro-jected area. The actual intensity over the really effective part of a bearing may be 260. Given good design there is no harm in the scraping done by Bell Crank ; the trouble is that it was done upon a bad design. It was ►ecitume of the constant II ft ing of the crank In flit, toil homil 1111U111(94 (11111 
cylinder to rid itself of exhaust staam at high speeds. A wheel so small that the back pressure becomes very great may exert less rail pull than a larger wheel which can allow a better effective pressure on the piston, and one of the more prominent facts of American practice to-day is the adaptation of larger and larger wheels. Americans seem deter-mined to run some trains as fast as they are run on this side, and they are going the same way to do it, only they have not tried single wheels. The illustration of the English en-gine on the P. R. R making a slow start is merely confirmatory of what one sees here with compounds. They are not always con-veniently stopped for effecting a good start, and as they have only a pair of 14-inch cylinders this is not surprising, but they can pull a heavy train when they are started, and get the 30-inch cylinder working also. Would Mr. Crane say if he found any trouble arising with the use of the brick arch in steel fire-boxes? W. H. BOOTH. 

At (d) we have a volume .4 and an amount of steam of 4 X 8.25 = 33; at (b) we have a volume _4 . Therefore a pressure 33 n--. n 4— 8.25 n. This must be equ1a615tonthe pressure found before, 8.25 n — 5 n 3 " 
n— 3.4 and —n = .294. 
Having thus ascertained the point of cut-off in the L. P. cylinder we will now trace the correct expansion line. The volume at (b) is as follows : In H. P. cylinder (1 — .294) = .706 In receiver 4. In L. P. cylinder (.294 X 4) = 1.176 
The Compound Engine. Editor American Machinist : I have read with interest Mr. Weightman's article in the number of the 28th, and would like to invite discussion about some points not quite clear to me. In the single-cylinder engine he figures the mean effective pressure quite correctly 28 96 pounds. Now this is purely theoretical, and it is all we can ever hope to get out of the amount of steam that he assumed to go through the engine. How is it possible that he can figure out a higher mean effective pressure t31.374) by using two cylinders? If this were true it would be next to a perpetual , motion, because it takes only 28.96 to comprem the steam from 8.25 to 165 (if done Iii ii prIturla ovliodorl. and wo would met buck 
5.882 
and the pressure is 165 : 5.882 = 28.05. At this point, as soon as the L. P. steam valve closes, the amount of steam (165) is di-vided into two parts—the one that always re-mains in the receiver and the one that goes through the engine. The value of the latter we know, but it will be interesting to figure it here again. In the L. P. cylinder we have the volume .294 x 4 1.176; 1.176 X 28.05 = 33; amount of steam going through engine. The first is the product of the volume 4.706 into the pressure 28.05, or 4.706 X 28.05 = 132; amount of steam remain-ing in receiver. At the end of the stroke   this whole amount of steam has been pushed into the receiver and occupies now only a space = 4 vols. Its pressure is there-fore 132 : 4 = 33 pounds, which demon-strates the correctness of my calculation. Of course with this point of cut-off the work of the t wo cylinders will not be the same for each. If this is the condition the actual diagrams must be laid out (allowing losses between cylinders) then the mean effective pressures mint be measured and compared, and the point of cut off in the H. P. cylin-der shifted accordingly, and new diagrams laid out. To lay out the curves for a triple-expansion engine is a little more complicated, and I will not do it here, but wait first for the criticism of this art He which is sure to come. F. F. N t(iK

pg 7 bott    weight and work it transinitte(l wore so great as to produce flexure of the shaft within the bearing, then it would be a positive benefit to make it larger in diameter, and thereby get additional bearing surface both by pre-venting flexure and increasing the surface area of the shaft. So it would seem but reasonable that a large and long bearing would stand a much better chance of having sufficient bearing surface than a short and small one would have. Increasing the diame-ter of the shaft beyond that necessary to attain the desired stiffness, would probably be of no benefit, from the fact that the increase of weight of the shaft would increase the friction enough to neutralize what would be saved by decreasing thy pressure per square inch of surface, unless the pressure were great enough to force out the lubricant. Increasing the diameter of a crank-pin will not greatly increase its tendency to heat, because if its diameter is double, the velocity of its surface is doubled, but this is almost neutralized by the fact that the pressure per square inch of surface is reduced just half. The main considerations therefore in deter-mining the diameter of a crank-pin should be, fist to give it sufficient transverse strength, and second, sufficient surface area so that the maximum pressure per square inch of surface may not exceed 14,000 pounds and which in marine engines seldom exceeds 800 pouno a true urmal P K, In speaking of surface area of -1 the normal arc --;ns I mean the pr,, in no way dependent upon the curvature of the pitch line 0 K, they are the same,for the same arc 0 H on all curves, and therefore all odontoids traced on the same side of any number of different pitch-curves by tlie “me point on the same roller are similar ',)/ -

But in this, their conclusion would bo at fault, as it would be in many other instances if they were to adopt that which would seem most natural concerning a place of this sort. The system of payment here, if such it can be called, is this : The employes are sup-posed to be paid once a month, upon which day of the month they never know, until they receive their money. Usually it arrives be-tween the first and tenth day. Twice within a year they have had to wait two or three weeks longer than the usual time, and i;,z,e they received pay for two months' work in the same week. To say that this irregularity and ofttimes delay is inconvenient, and that it sometimes brings distress upon some of the two hundred and fifty or three hundred machinists, black-smiths and foundrymen employed there, would only be stating the truth in mild terms. If the U. S. Government were hard pushed for money, or if it were some private firm which was financially embarrassed, this state of affairs might seem justifiable, but for a country with millions of dollars in the treasury is there any excuse ?

Machinery for Tin-plate lIl anufacture. If the New York Evening Post were less ignorant of the time and labor required to get a line of new machinery—for any manu-facturing purpose— perfected and in opera-tion on a large scale, some of its " views" upon the manufacture of tin-plates in this country might be entitled to consideration. Its latest misfit refers to an order which the American Tin-plate Co., of Elwood, Ind.—an account of the opening of whose new works was published in our issue of July 14—have just taken, through their Cin-cinnati agents, from Messrs. Norton Bros., of Chicago, for coke tin-plates equiva-lent to 5,000 boxes, 14x20 inch size, to be delivered within ninety days. Such an order is evidence that the Elwood Works are get-ting their operations down to a commercial basis. The order is further significant, be-cause of the fact that the plates are all of the lower-priced grades, such as are used in making cans, which it has been said could not be successfully made in this country. One thing is certain: the plates will be fluxed, before tinning, in palm oil, instead of ujuriatic acid, as is now and for years past has been a common practice in Wales. The sheets will, therefore, not be rust-breed-ers, ruining the goods packed in them. What especially seems to grieve the Post is the fact that Norton Bros. should presume to buy any tin-plates, in view of the pub-lished announcement as to the success of " their tinning machine by the palm oil process," as the Post graphically describes it. The Norton tinning machine now in use at their works has successfully tinned several thousand boxes of " black sheets," and cer-tainly DO mechanic will think ten or twelve months spent in perfecting it a long time in which to develop mechanism, such as the last 200 years have not—in Wales—been able to equal. The trouble with the Evening Post, in the main, seems to be, that it does not realize how many distinct mechanical operations are involved in producing tin-plates from the pig, or even from the black sheets. It affects to think that creating an industry of this magnitude is some little inconsequent operation — failure to so create it being proof that it never can be established. It l'►rgets that starting a Inn nithuactory or any 1,1nd lakes tittle, Evecially does it, take 11'ill'11 I lollut 5(1 wails he (►1 
ple who must be transported daily between the city and the neighboring towns on both roads must pass over it, in addition to which it happens to be at the junction of several streets, one of them the main business thor-oughfare of Elizabeth--a city of nearly 40,-000 inhabitants. Altogether about 700 trains pass over the crossing daily, which means that during the early morning and later after-noon hours, when the local traffic is heaviest, the crossing is taxed to the utmost capacity of its numerous tracks, and limited trains are often seriously delayed there. The work of tunneling under the roads for the streets has been going on for some time, and is well advanced, while recently the work of raising the Pennsylvania's tracks has been inaugurated, those of the Jersey Central to remain at the pres-ent level. The new station buildings of the latter road are completed, those of the other road being, of course, held back until the work of raising its tracks is completed. This improvement is one, the need of which has been long seen, but it has been delayed for some years by failure to agree with the city authorities as to terms. The improvement will considerably facilitate the movement of trains, and will probably pay the roads, although its cost will, it is said, approximate $1,500,000. 
      William P. Trowbridge. 
William P. Trowbridge, the head of the engineering department of the School of Mines, Columbia College, New York, died recently at the age of 64. General Trow-bridge (we believe lie had that title) was one of the best known engineers in the country. He was a graduate of West Point. He served the country through the war of the rebellion. He was a member of many scien tific societies, and was one of the thirty men who met in the office of the AMERICAN MA-CHINIST to organize the American Society of Mechanical Engineers. The cause of General Trowbridge's death was heart failure.

There is little room to doubt that the employ-ment of convict miners by contractors is bad for free labor, and when the legislature re-fuses to interfere there is some reason, if not justice, in the interpos'4ion of the miners. The pe )ple and the soldiers appear to side with the strikers, so called. 
A Chicago man whose name would at once be recognized if mentioned, recently spoke to the writer rather forcibly anent the World's Exposition at that city. His complaint was mainly in the direction that New Yorkers and every one else out of Chicago called the fair a Chicago institution. "Why," said the Chicagoian referred to, "this whole fair busi-ness is more a matter of New York than of Chicago influence. Chicago," said he, " is • an accident in the matter—nothing more." And we think lie is right. Literary Notes.

It should be mindful, also, of the numerous arbitrary advances in the price of tin-plates, from time to time, which the possession of a sure monopoly has enabled the foreign producers to exact from the peo-ple of this country, without any compen-sating benefits to the latter whatever.

Recently a South Brooklyn ferryboat crashed into her slip under full speed. All the ferry officials refused to say anything about the matter, in which, we think, they were decidedly wrong. It would be beyond nature if such accidents did not occur some-times, and the wisest plan is to let the public know just why they occur. In order that any intelligent opinion may be formed, when the statement of the average day's wages paid workmen is made, it should be accompanied by a statement of how many days a man has work in the year, and how many years he is likely to be able to continue his work. These statements, fairly made, would often very materially modify public opinion. 
It would appear that many cities in this country delay the payment of money due to workmen till the workmen sell their claims to middlemen at a good round discount.

Recently a South Brooklyn ferryboat crashed into her slip under full speed. All the ferry officials refused to say anything about the matter, in which, we think, they were decidedly wrong. It would be beyond nature if such accidents did not occur some-times, and the wisest plan is to let the public know just why they occur. In order that any intelligent opinion may be formed, when the statement of the average day's wages paid workmen is made, it should be accompanied by a statement of how many days a man has work in the year, and how many years he is likely to be able to continue his work. These statements, fairly made, would often very materially modify public opinion. 
It would appear that many cities in this country delay the payment of money due to workmen till the workmen sell their claims to middlemen at a good round discount. No particular blame attaches to the middlemen. Their operations represent a way of making money as legitimate, perhaps, as many others. But what about the city officials ? Is there collusion in the matter ? •41110•  At this writing there is serious trouble in the mines in Tennessee.

. ..•••• known In connection ■vith tests of water-wheels and hydraulic powers, undoubtedly knew much about such matters, but it is very evident that he has much to learn of the art of making books. If Mr. Emerson could have induced some engineering friend to edit his matter for him, and had left out of it all irrelevant matter, about which it is evident the author does not and cannot know anything worth the telling, it would have been better. The author has, for instance, views oil religious matters which differ essentially from those of most people, and in this book, purporting to treat of hydro-dynamics, he intrudes these views, and even introduces many engravings that are, to say the least, ill had taste, especially in a work purporting to treat of subjects with which these matters have no logical connection. There is much practical information in the book regarding water-wheels and water-powers, but it is not nearly so available for use as it might be if it were properly edited, arranged, and published without the irrele-vant matter referred to. The book is pub-lished by the author at Willimansett, Mass. Price, $1. 
AMERICAN YACHT LIST FOR 1892.—This is a publication which is of special in-terest to those who either own or are other-wise identified with yachts, or yacht build-ing and sailing. It is a superb book of 480 pages, bound in white canvas covers, ornamented in blue, and contains beautiful fac-simile chromolitho-graph illustrations of all club flags and private signals of yacht owners. There is also a complete register of the yacht clubs of the U. S., British Provinces, Royal Bur-muda Islands, Royal Jamaica, Habana and Argentine Yacht Clubs, with lists of officers, addresses of secretaries, names of yachts, with official numbers, signal letters, dimen-sions, designers, builders, etc. Full in-formation is given regarding regattas and races, with rules of measurement, time allow-ance, etc. There is also an alphabetical list of owners. In the list of steam yachts, for instance, which is in tabular form, the names of the vessels are given alphabetically, with

One Way to Improve Steam-engine Economy. 
Improvement in the steam-engine for the past fifty years has consisted mainly in put-ting into practice what was already known to be desirable. In this, as in most other affairs, it was found to be one thing to know what was desirable, and another thing to ac-complish it. Better plans of construction have rendered the use of high steam-pressure and high piston-speed more common, and these, with better workmanship and careful attention to details, have brought about better economy. Considered as a machine, recent improvements in the steam-engine have been important. Undoubtedly there is room for further improvements in these directions—there is no such thing as standing still—but the ground has been so well covered that nothing radical is to be expected, except it come from the establishment of new and important facts in the science of steam engi-neering, and from a direction not now very obvious. Improvements in tools and ma-chinery for doing good work cheaply have had much to do with improving the construc-tion of the steam-engine, not only by affording the means for doing so, but frequently by pointing out the direction for improvement. Aside from this, the introduction of better instruments for, and better methods of, meas-uring effect has been important. But steam engineering embraces not only the designing and construction of steam-engines and boilers, but their management, as well, and here there is room for general pro-gress in the direction of better economy. If not a new field, it is one that has not been as extensively cultivated as it ought to be. Users of steam-engines are, owing to long and persistent effort, fairly well educated in the economy of paying for good design and construction ; but they do not to the same ex-tent appreciate the value of good manage-ment. Sometimes they are, so it seems, of the opinion that there is not much in the way of economy in the every-day management of a steam plant, except what is comprised in stopping and starting, and in keeping up the motion for the required number of hours ; their interest ceases after hiring an engineer just eom potent f(?r this duty, or employing a , a‘tont etigInewr who finds no (.0 OpiTIL

probable that in many instances they would find something startling in the difference. Further investigation would sometimes re-veal incompetence in the engine-room ; but, perhaps, oftener the cause would be found in their own refusal to second the efforts of a competent engineer. Either would be about equally fatal to good economy. Not that the every-day economy of a motive plant is likely to equal that of a closely conducted test of the same engines and boilers, but the latter shows the possibility that may be closely ap-proximated. To insure that the best at-tainable results are being obtained, it is abso-lutely essential that comparisons be readily made. This has been provided for by modern science and common sense, and to fail to make use of what is thus provided is to put to one side one of the best known means of securing economy. When, as is often the case, the results of actual practice are about fifty per cent. those of a fairly conducted test there is good reason to look for some-thing wrong. But means of easily making comparisons must be provided if any advan-tage is to be taken of the experience of others. Economy in motive power is made up of small things, and observations must be specific as well as general. When the operation of the motive plant gets outrageously bad, an expert is called in to straighten matters out. But this is not until after a good deal of waste. When it is done, the cost of discovering the trouble, to say nothing of the cost of the remedy, is likely to be more than that of previously supplying the engineer with such things as he required, and by reasonable encouragement making an ex-pert of him, ready to suggest preventives in-stead of costly remedies. The interests of manufacturers call for economical motive power, and a very apparent direction for improvement in this respect is through the engine-room. We hear a great deal of the need of skilled workmen in other branches, and but little of the need of skilled engineers, yet economy in manufacture must begin in the engine-room. Engineers must to a greater extent than most other workmen educate themselves ; they ought to be afforded every reasonable opportunity for doing so. Not out of any sentiment, but because it is policy to do so. Whenever this is (lone we hiLvo novor heard vomidailit that It did 
Territorial Limits of Natural Gas. 
Among later developments of the natural gas boom are published statements that " pay-ing " wells have been discovered, and are being " worked " in a number of towns as far removed from the original centers of pro-duction as Central and Northwestern Ohio. We believe, also, that equally confident claims are made for some Southern towns. If the published statements of the new " finds " are well based, it would seem that the territorial limits of the natural gas " fields " are not yet very well defined, or with present knowledge of the subject capable of very close defini-tion. 
A New Railroad Brake. 
It is not often that a really great invention is born of what a lawyer would call " malice aforethought." A Virginia inventor is living proof that such an exception may occur. In a local paper he publishes an advertisement highly laudatory of an automatic railroad brake, which he has " discovered " and pat-ented, but omits to publish any explanation of its construction or the principle on which it acts. In the published card, he says he was standing at the " station " as a freight train went by, and noticed that the brakeman tried to stop the train, but found some difficulty in doing so immediately. The future inventor thereupon remarked to some gentlemen present that he proposed to get up an automatic brake, which would stop the train without " all that trouble." He now announces that, after four years of hard study and almost sleepless nights, he has accomplished his object, and closes by ex-pressing his hope that railroad managers will examine his " patent right " at once, that they may " relieve the poor, worn-out, rest-broken and frozen brakemen;" his " greatest desire " being to see them released from their exposure and sufferings. His next greatest is not stated, but it is to be hoped that rail-road managers will be willing to gratify it, if it is shown to their mechanical satisfaction that our Virginia friend's claim for his inven-tion are as well based 1LH w„ think, however, Hint. toast, riiilr11a1l mitiingorti

 it, is running In the work, or when the work Is running on the drill ? A.—Probably it will be when the drill is ru:.ning in the work, as the chips have then a better chance to work out of the hole, as they are alternately carried over and fall under the drill. 
(114) H. V., Greenpoint, N. Y. , writes : 1. I would like a permit to run a small steam yacht. Whore should I apply for it? A.—At the inspec-tor's office, in the New York Post-office. 2. How much power will I get from an engine 234"x3", at 60 lbs. boiler pressure ? A .—Probably you may get nearly one horse-power. 3. Is a screw 14" diameter and 20" pitch too large ? A.—About right. (115) A. E. H., Bradford, Conn., asks : how to pulverize resin economically, in large quantity ? A.—A method used in some large paper mills, is to use a common corn-cracker, such as in use in some country grist-mills for breaking up corn in the ear. A machine of this description can be so adjusted (like a coffee mill) that resin can be ground to any desired degree of fineness. (116) Laurel, Ind..; asks : 1. What is your opinion of suspending the rear end of a tubular boiler by means of a strap passing entirely around it, instead of by hooks riveted on? A.—W e can see no objections, except-that the expansion and con-'Taction of the long strap will bring about a little more up-and-down motion to that end of the boiler. How many 4" tubes should there be in a 42" hell ? A.—Barr gives the number of 4" tubes for a 42" shell as 25. 

 E. D. asks : 1. What is the method of computing the specific volume of steam at any given pressure ? A.—We cannot give you a satis-factory rule. You will find this matter discussed in Steam Engineering, by Nystrom. You will find in any work on steam engineering tables that will give you the desired information. 2. How can I compute the horse-power of a compound engine without the use of an indicator ? A.—The work done by a compound engine will generally be a little less than what would be done in the low pressure cylinder alone, working with the swill., ratio of expansion. .

he may favor ball bearings, knows that there was wear of both journals and balls, and de-cently accurate measurements, as measure-ments are made to-day, would have shown this to have been true. When men start out to write of things of which they have no knowledge, they generally fail to impart information. This brought out a communication from Mr. Simonds, which we give in part below: " On page 8 of the AMERICAN MACHINIST of July 28th, I notice an article, Ball Bear-ings for Street Cars, in which you comment editorially on a statement credited to the Springfield Republican. " I do not hold myself responsible for the language that-• may be used by newspaper men in describingthe work that I am doing, but I can safely say that, if you will come to Fitchburg I will show you some results that will attract your attention, not only in anti-friction bearings, but in other directions that will prove of interest to your readers. " Until a short notice was given in the Boston Herald, July 14th, from which the Springfield Republican copied, I had per-mitted nothing to be publicly said in refer-ence to my more recent original work, and July 17th the same correspondent had pub-lished the inclosed, which pleak return to me after reading. " I am quite well aware that it has been considered an axiomatic truth that where there is a movement of two bodies, on or over each other, there must be friction, and where there is friction there must be wear. I am not prepared to prove that this is not so, but when bearings have run for months doing considerable work, and the oil in said bearing is not discolored, it would seem that, if that point has not been reached, it cer-tainly approaches it. " During the month of May I employed Mr. Coleman Sellers, of Philadelphia, pro-fessionally, to investigate what I have been doing, and report his opinion to me. He was in Fitchburg two days, and has taken two months to get facts from all directions, bearing on the subject. His type written report of ten pages came to me two days ago, and you will find it interesting reading." When the above item, to which Mr. Simonds refers, was written, we had no idea that lie was the inventor of the particular journal bearing to which reference was made. However, that would have made no difference. In conversation we found that Mr. Sim-onds believed that we had done him an injustice as regards ball bearings. We went with him to see the bearing to which the ,k(pringficht lleprihtiedn, evidently renirrc AUGUST 25, 1892 .
without change of form to any appreciable extent. Mr. Simonds has devised a large number of adaptations for his various processes, relating mainly to the use of ball bearings for a great variety of purposes. His efforts in this direction are worthy of serious con-sideration.

The accompanying engravings represent a class of work it is intended for. It will be noticed by referring to the outline view that there are four changes of feed, the motion being transmitted through splined shafts and covered bevel gears to a central vertical shaft, from which the screw is driven. The base upon which the table rests is cir-cular in form, graduated on its outer face, as shown, and the swiveling plate is secured to the base by means of bolts, which engage with T-slots and lock it firmly in place, these bolts being so placed as to be always in crank being always in place and ready for use. All movements of the table in every direction are graduated by dials, indicating 04 the movement in .001". The feed works in either direction without change of belt, and is automatically tripped in either direction. The table has a quick-return motion of three to one. The foot-stock center elevates for taper work, and the head-stock or spiral head swivels in a horizontal plane either side of the center line. The spindle is of steel, 31" diameter, and runs in phosphor-bronze bearings, the front one being taper and the rear straight, with provision for taking up wear. A I" hole passes entirely through the spindle. The overhanging arm is 3-i" diameter, and is clamped over each box, passing through a cylindrical brace which extends from one upright to the other. Instead of a fixed center to support the outer end of the arbor, it is provided with a hardened steel cylindrical bushing, in which a hardened steel extension of the arbor runs, thus providing a bearing that is durable, al-lows for expansion, and is in every way sat-isfactory. The vise furnished with the machine swivels, and has a graduated base. Its jaws aie 6" wide, 1-27-" deep, and open 3k". Table is 6" wide, 33" long, with an automatic feed of 18". Work 91" diameter 15" long can be swung on the centers, and a 12" cutter can be used under the arm. The cross motion of the table in line with the spindle is 6", and the vertical movement 17". Slowest auto-matic feed .0045" per turn of spindle; fast-est, .0215". Cone pulley is for a 3" belt, and countershaft is furnished with two friction clutch pulleys. Machine weighs, complete, 2,000 pounds, and is built by the Cincinnati Milling Machine Co., Cincinnati, 0.

that he vvam the inventor of the particular journal bearing to which reference was made. However, that would have made no difference. In conversation we found that Mr. Sim-onds believed that we had done him an injustice as regards ball bearings. We went with him to see the bearing to which the Springfield Republican evidently referred in its extract, as we quoted. While we had no means of making a critical examination of this bearing—no data from which to work—we are entirely free to admit that it showed no visible wear. But all this does not change our opinion that there had been wear. It will be noticed that in the item to which Mr. Simonds refers we did not say that the wear had not been enormously reduced ; we contended then, as we do now, that there had been wear. We pulled a car fitted with these bearings along the track, back and forth, and can testify that there was a wonderfully small effort required to move it. The presump-tion is that the friction is very slight, and that the wear is correspondingly slight. We believe, however, that there is wear, as we previously intimated. In Mr. Simonds' shop, which is very com-plete in its appointments a good many ex-perimental processes are going forward. He says that by processes for grinding balls he can produce perfect spheres, exact to size, and instanced it by holding four balls, selected at random, between the measuring points of a micrometer caliper, turning the caliper over from side to side. He has also devised a means for hardening balls, and, in fact, other pieces of all kinds, by which the hardening process is continued from brine or water to oil without interven-ing exposure to atmosphere. Mr. Simonds' researches also cover a means of using the cementation process by which he makes the outside of a bush or sleeve, such as to harden on the inside or outside, as desired, or to be susceptible of hardening in any of its parts, the other parts remaining soft. Mr. Simonds claims that by his various processes he can make balls that will stand intense pressure without giving way, and that he can harden steel bushes or sleeves 

UNIVERSAL MILLING MACHINE. 
milling machine, which has been designed with special reference to the work usually done in a tool room. We have before illus-trated machines by the same builders which had some of the features of this one, but were intended for a different class of work, the present machine being somewhat lighter and smaller, though it has good spindle power and is fully as stiff and strong as is consistent with convenient handling on the

a convenient position. This form of base gives, of course, a uniform bearing at all angles of the table, and there are no projec-tions to strike the face of the column when setting to an angle, thus requiring the cut-ter to be placed further from the main bear-ing than would otherwise be the case. The knee is raised and lowered by a large screw, operated by a horizontal shaft, which is placed at such an angle as to admit of its
