There were no "ifs" about it, they simply had to have helical gears in the plant in which the gears shown on the opposite page are made. It seems, too, they had to run up against all sorts of trouble in cutting them. The gears never came off the machines they were formerly using accurate enough to be run without a lot of expensive fussing over them also with-out numerous rejections in assembling and testing.
Now, they use Helical Gear Shapers and their worries are ended”really ended. The gears cut on the Helical Gear Shaper come right off the machine ready for service.

Work -, ts Fig. 158
—Racks may be applied horizontally, vertically or at an angle to the clamp to suit the work piece or desired compactness any milling milling fixture, because it saves time and waste. Instructions are stamped on the tool: "Use feeler gage." Clamps and supports for heavy work in large milling fixtures operate on the same principles as in smaller fixtures. Both large and small fixtures usually have cast-iron bodies, the larger ones being extensively ribbed and designed with comparatively light webs between the ribs. This feature increases strength and reduces weight and cost. The surface cuts on any cast-iron body should be as few as pos-sible, because the maximum strength in cast iron lies mostly in its "skin." To machine off the skin sacrifices considerable strength. Cast-iron cast-ings seem to cure with age. An equalizer, eye-bolt and nut lever clamps and releases two pieces of work in Fig. 146. Coiled corn-pression spring A raises and releases equalizer B from the work when nut lever C is loosened. The sketch rep-resents a cross-section at right angles through the center of the fixture. Two opposed "floating clamps" D, causes a side registry of the pieces before clamping. If the work is long, four or more opposed clamps are used. A tension spring is shown attached to each of the clamps, and passes through a clearance hole in the fixture. If the work is too long for a single-unit fastener, two or four of such units are used, and operated un-derneath by a compound equalizer bar mounted under a centrally posi-tioned nut. For quick action, a flat-faced cam can be substituted in -)lace of the nut. For positioning the milling table and fixture in reference to the cutters for making the first cats, a steel gage of the same cross-section as, the finished piece is used, or a "feel gage" can be attached on doeire,ip the fixture for the purpose. The simplest "feeler gage' is a vertical pin driven in the fixture, with a flat provided on it which faces the cutter for gaging. Figs. 147 to 157 inclusive show eleven rear-end views of conven-tional methods for guiding clamps, slides and thrust types of milling supports. By referring to these principles, a suitable design is often found or suggested. The rack and pinion principle for clamping is sketched in Fig. 158. Racks and pinions have been suc-cessfully applied in many types of tools and machines. They are used in jigs, milling and assembling fix-tures, dies and special machinery. This is one of the most dependable movements known in mechanics. It is an inexpensive design because many sizes of racks and pinions have been commercially standardized and can therefore be economically pur-chased. Racks and pinions have several applications in clamping. The type shown uses the rack in a horizontal position, but it could be vertical to the clamp, or positioned at con-venient angles relative to the clamp. This is often necessary in suiting the shape of the work piece, or for mak-ing a compact tool design. For effi-cient holding power, dimension A on the clamp should not exceed the pitch diameter of the pinion more than about 11 : 1. The conditions shown in the sketch are sometimes advantageously reversed ; that is, the rack end becomes the supporting member, and is advanced or with-drawn by rotating a handle arm attached to the pinion. In this case the handle must be positively secured in its locked position by using a suit-ably placed clamp, cam or key.

DURING the past year Chevrolet Motor Division of General Motors has spent millions on new equipment to modernize its factories and increase its output. It has installed much new equipment in its various manufacturing departments for the '38 season. A huge plant at Buffalo which is expected to enlarge the company's capacity of motors and axles some 1200 units a day is being rushed to completion.

This new welding machine at the gear and axle plant at Detroit performs six welding opera-tions at the same time. The rear axle housing rotates on the machine to permit welding of six spring seat flanges


having just closed one of the best years in its history, has made a capital outlay of around $3,500,000 in preparation for a big year in 1938.

About $1,000,000 represents new equipment, much of which has been put into the motor machine shop. In some cases, this equipment duplicates that already in the shop and has been installed chiefly in the cylinder block, crankshaft and connecting rod lines. The machine shop capacity is being brought up to a basis of 60 units an hour.

Management How The Flat Turret Lathe

Line Between Excessive
The dividing line between excessive and insufficient stock must be drawn in each individual case. The amount of capital tied up in raw material, supplies, stock in process and finished product should not be greater than that which is necessary to get the greatest output per dollar of investment. There should be a constant supply of material throughout the entire work. The stock in process should flow through the plant in a rapid, thin stream, but with no greater quantity than absolutely necessary to insure a steady supply for all the workers, including assembling and selling workers. Yet, in spite of these true economic principles, there are many plants whose buildings and immense stock • carried represents three times the necessary investment. In these plants capital is often tied up in ways that actually throttle the output of the entire business. Furthermore, this is frequently done by increasing the portion of the investment that is irrevocably tied to the existing product, thus not only reducing the earning power of each dollar invested, but also increasing the hazard by tying the capital to the present product, which soon may be unsuited to the market demand. One of the most common errors in this respect is the one that regards the reduction of the labor cost as the paramount consideration. While the net cost per piece is natur-ally an important element it should neither eclipse the question of profit per dollar invested, nor the risk of the capital tied up.

October 20, 1937 The Machine-Tool-Recession-of-1929 The Comeback is Slow in 1938
(The War spending by the world will do it, not the US goverment mandates.)

AMERICAN MACHINIST, October 20, 1937 It's ratio of 65 per cent of old equipment and would have to step up activity to 1929 in order to regain its lost ground and bring the percent-age back to 48 as reported in 1930. During the 21--year period that has intervened the industry actually operated at a point (131) between these two levels. It has, therefore, gained some ground and has come back part way. The machine tool index of orders was 86 per cent for 1935. In 1936 it was 136.6 and during the first six months of 1937 it averaged 210. If the level recorded during the first half of 1937 is continued through the last half of this year and through the years 1938 and 1939, the over-all average for five years will be 170.5, still somewhat under the estimated index required to restore the 1930 ratio. How Estimate Was Made The estimate of the present status of old machine tools in place was made as follows: The machine tools built during 1935 were reported by the Census of Manufacturers. From this was deducted a percentage for machines shipped abroad, leaving those built for installation within the United States. This figure for 1935 was extended for 1936 and the first half of 1937 by applying the ratio of the Machine Tool Builders' index during 1935 to that reported for the later periods. In this way, it was possible to arrive at an approximation of the new equipment installed during the 21-year period. This figure was added to that re-ported for the new machines in place as of January 1, 1935, as shown in the American Machinist inventory. However, during this 22- year period, there were a number of machines reported as new in 1935 which passed over the ten-year mark. These machines were those installed between January 1,1925 and July 1, 1927

Accordingly, a similar esti-mate of the machines installed dur-ing this 22-year period was made in the same manner. The Census of Manufactures for 1925 was used as a basis and was modified by the Ma-chine Tool Builders' index in order to secure he number of machines in-stalled over the period in question. When this figure was found it was deducted from the sum of the new machines as already computed, to give an estimate of the new ma-chines in place as of July 1, 1937. Having obtained this figure, the question arose as to whether these machines were installed as replace-ments or as additional equipment for

1925 1930 1935 1937 (July 1) expansion. A knowledge of the in-dustry would lead to the assumption that by far the greater portion of these machines was installed as re-placements. In some cases, one ma-chine replaced two or more others, which tended to reduce the total number in use. This substitution of a more efficient machine for several older ones would tend to balance other units installed for purposes of expansion. Therefore, for the pur-poses of this estimate, it was as-sumed that the total number of ma-chine tools in place was constant over the 22-year period. Further as-surance for such an assumption was gained by the fact that there was only a slight change in the total number of units in use between the 1930 inventory and that for 1935. Comeback Is Slow The new machines as computed were then deducted from the total units in place to obtain a figure for . the old equipment. From this figure the percentage was taken which came to 61 per cent as previously noted. Some. of these figures involved in this computation are given in the ac-companying table. In order to carry this estimate still further certain groups of machines were selected in order to see what progress had been made in replacement and to compare the percentages reported for them with those obtained by actual count 21 years ago. These groups are also shown in a table, and as might have been expected there is a consider-able variation in the results obtained. While most of the groups show a smaller percentage of old units than was reported in 1935 a few are in a less favorable position. This af-fords further proof that although the metal-working industry has made a fair start in bringing its physical plants up-to-date, there is `still much to be done and much lost ground to be gained. The length of time it takes to rehabilitate the metal-work-ing industry emphasizes the limita-tion under which the country would be placed should a national emer-gency arise. It points to the necessity of maintaining active modernization programs at a high level in order to put plants on an efficient basis for peace time operation and in readiness for national defense.

The Case of a Man Who Tried to Win $5.22 and Failed

He was a big fellow too, and thought he had an easy proposition before he started in. But he lost because the Allen Safety Set Screw cannot be broken by human strength. Here's the story: Our salesmen carry a test block with them, and when they show the Allen Safety Set Screw to machine men they invite all manner of tests. One of our men was showing the screw to a superintendent of a large
Jersey plant and in the course of his argument, the superintendent's big husky assistant came along. When asked what he thought of it, he replied that it was like all others and they all break. Our representative laughed and said he was instructed by the office to give five dollars to any man who broke one of our screws in a fair test. Then he went on talking to the superintendent. A minute later they heard the big fellow working at a vise. Turns out he was putting the
The Allen Safety Set Screw
to the test. From experience with other screws he thought the five dollars would be his with one turn of the wrench. But he tugged and pulled, he put all of his strength into it, and finally came over and admitted that it would take more than his strength to even make a mark on the screw. The Allen Safety Set Screw is a better kind of screw—it may look like some screws you have seen, but the similarity ends right there. The Allen is made from a High Test Steel Bar, by a Patented Process, which strengthens the metal over 30%. It will not upset or mushroom in the hole, it will not break, it can always be taken out easily. The screw will stand all the wrench will stand and more. We invite you to test this screw, test it in any way you want to, put any amount of pressure on it, and watch it hold its own. We will gladly send you samples for the test, because we know the result of any test you make, will show you that here at last is the safe screw, the screw that will put an end to set screw troubles and delays.

Two more features in which SKF Double Row Self-Aligning Ball Bearings are supreme. Machines seldom operate under ideal conditions, hence it is important in designing that hard knocks from severe service and possible abuse at the hands of careless or inexperienced workmen be taken into consideration. SKF Self-Aligning Ball Bearings best meet these requirements for many reasons. First, their mountings can be simple, strong, inexpen-sive, with liberal provis-ion for lubrication; and the bearings themselves can be perfectly sealed against dust, dirt, grit and other injurious agents. Second, their capacity is ample Our double row construction distributes the load to best to meet severe overloads. possible advantage.

our provision within the bearing itself for absolute automatic and instantaneous self-alignment compensates for shaft spring, completely eliminating the necessity for an aligning cradle or ball seat, usually required in ordinary journals. Fourth, the simple one piece retainer of Swedish Lancashire steel leaves nothing within the bearing that can work loose to cause noise or failure. Fifth, races and balls of the highest grade of Swedish crucible steel, uniformly hard throughout. Sixth, a minimum number of parts assures extreme durability Machine builders who want higher efficiencies, greater output and reduced lubrication and attendance costs can profitably investigate SKF Bearings. Making the change from babbited or other power consuming bearings invariably effects a logical improvement guarantees service, long life and absolute reliability. Tell us your side of the bearing story and our engineers will solve the problem. Write for our literature.

Slocomb Center Drills

Many Center Drills Break because the largest chips from the countersink clog the small-er chips from the drill point. As a result the drill point breaks off. In making Slo-comb Center Drills we have milled them so as to have plenty of room for all the chips to get out and not clog. This has proved a valuable point as it has resulted in less breakage. If you haven't used Slocomb Center Drills you should Get a box and try them.

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 let's go- let's get started on the right track again. This business de-
depression will last just as long as the people of this country 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 threatening 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 profitable 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 trailof
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.
