On the evening of June 22, 1912, former President Theodore Roosevelt asked his supporters to leave the floor of the Republican National Convention
The Republican Progressives promised to increase federal regulation and protect the welfare of ordinary people.
Roosevelt maintained that President William Howard Taft had allowed fraudulent seating of delegates in order to capture the presidential nomination (Pre Trump in 1912)

Progressivism is a political and social term that refers to ideologies and movements favoring or advocating changes or reform,
usually in a statist or egalitarian direction for economic policies (government management) and liberal direction for social policies (personal choice).
Progressivism is often viewed in opposition to conservative ideologies.

Tools in a Cream Separator Plant

In an earlier article dealing with the methods of the Iowa Dairy Separator Co., of Waterloo, Iowa, reference was made to two of the lines of separators manu-factured by this firm, but the illustrations were confined principally to tools for handling one of these types only. The present article will deal specifically with methods employed for machining certain important members entering into the con-struction of the other type of separator. The view in the . testing department, Fig. 1, showing a number of this class of separators under the "running off" belts is presented as the first illustration in order to show the general form of the frame, the machining of which forms the basis of a major portion of this article. The separators in this view, as will be noted, are shown without the upright arm which, when the machine is fully as-sembled, is attached to the planed pad on the side of the frame to carry the milk pan. This arm, like the frame which car-

By F. A. Stanley The operations involved in the machining of separator frames include boring the bowl spindle and gear shaft bearings, facing and turning the bearing bosses, boring and facing the neck, mill-ing a pad at the side for the up-right arm and milling the bear-ing surfaces of the arm itself. The jigs and fixtures for these processes are of unusual inter-est and like the cutting tools are constructed for producing accu-rate results. This frame carries the shafts, gearing and bowl spindle constituting the entire mechanism of the machine. The spindle is journaled at the lower end in a bronze bush which is fitted in a steel box tapered externally to fit a taper seat bored in the bottom of the cast-iron frame. This taper ing device which is utilized in locating the work in the jig before the clamps and screws are tightened. The centering device positions the frame to be bored, so that the round neck of the frame will be concentric with the jig bushing and the bearing opening will be bored central with the whole frame. This device has a round body like a chuck, with three jaws which are hooked at the back to drop over the top of the work and provided at the front with pro-jections which are turned taper on the outside as shown. The conical surfaces on the jaws cor-respond in taper to the internal cone formed in the mouth of the sleeve B which is finished externally to fit the fixed guide bushing in the top of the jig, and also to fit the cylindrical opening bored in the chuck face. The separator frame to be bored is slid into the jig with the centering device on the frame and with the three jaws in

FIG. 1. A LOT OF CREAM SEPARATORS UNDER THE "RUNNING-OFF" BELTS BEFORE ATTACHING THE UPRIGHT ARMS ries it, is machined with the aid of a num-ber of interesting tools, also illustrated.

MACHINING THE FRAME

The first operation on the cone-shaped frame consists in facing the bottom true to facilitate later machining processes, and also to provide a suitable surface for resting upon the two-legged casting which forms the base of the whole separator. The facing is accomplished in a lathe and the frame is then ready for boring for the center bearing. seat and the cylindrical opening through the upper part of the frame must be bored exactly in line with each other. This is accomplished with the tools in Figs. 2 and 3.

THE BORING JIG AND TOOLS

The general character of the jig will be seen from Fig. 2 which also shows clear-ly the form of the casting to be bored. The boring tools in Fig. 3 are arranged in the order in which they are used. The chuck on the shelf at A is a center- contact with the top of the casting. The bell-mouthed- sleeve is slipped into the jig bushing and the work is then moved on its base until the sleeve enters the open-ing in the chuck face and at the same time passes down over the cone-shaped projections of the jaws. The work is then central and is secured in place by the screws and clamps shown in Fig. 2. SEQUENCE OF OPERATIONS The first cutting tool used is the bor-ing bar and cutter C. This rough bores

and extends nearly to the bottom of the frame in order to support the drill near the working point. It is itself supported not only in the fixed jig bushing but also in the 2A-in. hole reamed in the upper part of the work as described above. It is in order to provide this complete support for the long bushing and assure the boring of the lower hole in alignment

FIG. 2. BORING MACHINE WITH JIG AND TOOLS FOR SEPARATOR FRAME

the upper opening in the frame to a diam-eter of 2,1% in., after which the reamer D is run down through to size the hole to 2A in. Both the cutter bar and reamer, like other tools in this set, carry their own cast-iron bushings which run, in the hard-ened-steel guide bushing fixed in the jig. The next tool applied is the twist -drill E which is supported in the long- bushing F and which drills a -RI in. hole in the bottom of the frame as the first step in forming the seat for the taper box which carries the lower end of the bowl spindle. The bushing for this drill is 15 in. long with the upper one, that the latter is bored and reamed true at the outset to 2A in., which is not the permanent diameter of the hole but merely a size given it tem-porarily to facilitate the operations that follow.

FURTHER BORING AND REAMING

The twist drill is followed by the bor-ing bar G which carries a flat cutter at the small end for boring the lower hole in the frame to a size suited to the small end of the taper reamer. A larger cutter

FIG. 4. ROUGH BORING UNDER DRILLER

in the body of the bar at the same time rebores the upper opening in the frame to within 1/64 of its final size, which is to be 23/s in. The boring bar is well supported at both ends, the pilot at the lower end having a keyway and carrying a bushing which revolves with the bar in a fixed guide bushing in the bottom of the jig. This bar is followed in turn by a sec-ond bar H which is guided in the same manner and which enlarges the lower hole for half its depth to a size which leaves little material for the taper reamer to re-move. The large cutter in this bar fin-ishes the upper hole to within 0.005 in. of size and this amount is removed by the finishing reamer I. The taper reamer J is then used to finish the bearing seat at the bottom. The bushing for the latter • reamer is very long and, like the drill and boring-bar bushings, is carried both in the fixed bushing in the jig and in the upper opening bored in the work.

FIG. 14 FIXTURE USED IN MILLING UPRIGHT ARM FOR SEPARATOR
the tools in Fig. 9. The cutter head car-ries two inserted blades, one for turning the boss, the other for facing and round-ing the corner. The inner ends of the bearings for the lower gear shaft are faced by clamping the work on a central seat on a miller fixture, Fig. 10, and using a flat cutter which is carried in a bar in the miller spindle. The shaft which runs in these bearings must be located endwise very exactly in order that the driving gear which it carries shall engage properly with the spiral teeth on the vertical-bowl spindle. To face the inner ends of the bosses correctly a dimension is established from the center line and in setting the fixture and machine for the starting of the job a definite relation is fixed between the cutter and the center of the work. With the aid of the micrometer dial on the crossfeed screw the work is fed to the flat cutter until the boss is faced off to the specified distance from the center. The locating plug in the front of the fixture is slid into the bearing hole in the frame to position it properly before it is clamped to the fixture. The end of the facing bar in the miller spindle enters the bearing for support during the cutting operation.

FIG. 15 MILLING AND DRILLING
The separator frame is shown in Fig. 11 on a miller fixture where the rear face of the frame is machined to receive the upright arm that carries the milk pan.. The frame is placed on an arbor between the centers on this fixture and is located by the finished bosses so that the milled surface will come square with the shaft bearings and bowl spindle. The surface milled in this manner is drilled for the screws for holding the upright arm, by means of the jig in the multi-spindle machine, Fig. 12.

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. For what is the gain if the means for reduction of the net labor cost re- Jones & Lamson Machine Company

Time Saving Features In The Prentice Radial Built By Prentice Bros. Co., Worcester, Mass.

4' Arm Radial Pulling an 8" Pipe Tap—Ball-bearing throughout.

THE EASE AND FACILITY of positioning the arm and spindle, the roller clutch permitting hand feed ahead of engaged power feed—which alone enables an average saving of thirty seconds in the starting of every hole—the dial depth gauge, the automatic stop motion and the five-to-one quick return of the spindle are among the time saving features.

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.

RUGGEDNESS-SIMPLICITY
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.

Third,
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.

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.

LETS GO AMERICAN MACHINIST-Section Vol. 56, No. 1
LET'S START RIGHT NOW!
.
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 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.
