UNITED STATES PATENT @FFiQlh JAMES R-ElLLEY, OF BUFFALO, NEW YORK, ASSIGNOR OF ONBHALF TO THOMAS A. BISSELL, OF SAME PLACE.

DIE FOR FORGING TRUCK-EQUALIZERS.

SPECIFICATION forming part of Letters Patent No. 387,812, dated August 14, 1888.

Application filed May 31, 1888.

To all whom it may concern.-

Be it known that I, J AMES REILLEY, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Dies for Forging Truck- Equalizers, of which the following is a specification.

This invention relates to an improvement in dies for forging the truck-equalizers which connect the axle-boxes of the truck, and which support the springs upon which the car-body rests.

The object of my invention is to construct a pair of dies whereby these truclcequalizers can be produced more expeditiously than heretofore and at the same time be finished in a superior manner.

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of my improved dies. Fig. 2 is a side elevation thereof. Fig. 3 is a rear view of the same. Fig. 4 is a vertical section of the dies in line a" m, Fig. 1. Fig. 5 is a top plan view of the lower die. Fig. 6 is a bottom plan view of the punch or upper die. Fig. 7 is a vertical cross-section in line y 3, Fig. 4. Fig. 8 is a similar view in line z 2, Fig. 3, the section being taken at right angles to Fig. 7. Fig. 9 is a perspective view of one of the equalizers, showing the form thereof previously to being operated upon by the dies. Fig. 10 is a perspective view of the finished equalizer. Fig. 11 is a top plan view of one of the end portions of the equalizer.

Like letters of reference refer to like parts in the several figures.

A represents the body or main portion of the equalizer, the end portions or legs, a a, of which are bent or curved at an angle to the body portion A and terminate in angular feet I) 5, arranged parallel with the body portion A, and whereby the equalizer is secured to the axle-boxes.

In the construction illustrated in the draw ings the curve at one end of the equalizer is shorter and more abrupt than the curve at the opposite end of the equalizer, and the leg to is provided with a shorter foot than the leg (0. In trucks having three axle-boxes on each side Serial No. .ZTQSIQ. (No model.)

two of these equalizers are employed, the long feet of the equalizers being secured to the two outer axle-boxes and the short feet to the intermediate or middle axle box. \Vhen the truck has but two axle-boxes, a single equalizer is used, and both ends thereof are curved correspondingly and have feet of the same size.

G represents the lower stationary die, which is secured to the. anvil-block of a steam or power hammer. The die 0 is provided on its upper side, near one of its lateral edges, with a long convex face, (I, for forming the leg at, having the long curve, and at the base of this convex face with a horizontal rectangular recess or depression, (1, corresponding to the shape of the short foot I).

0 represents a short convex face arranged near the opposite lateral edge of the die 0, for forming the leg it, having the short curve, and e is a horizontal rectangular recess or depression arranged at the base of the convex face 6, and having the form of the long foot 5.

F represents the punch or upper movable dic, which is secured to the head of the powerhammer. The punch F is provided with concave faces ff, corresponding to the convex faces d c of the lower die, 0, and arranged directly above the same, and at the lower end of these concave faces with flat horizontal working faces g g. The faces g g are notched or recessed, as shown at h it, so that the concave faces f f" will extend to the flat working-faces g g, the notches h h fitting over the legs a a of the equalizer in forging the same.

Thelower die, 0, is provided between its convex faces of e with a flat horizontal anvil or face, l, and the punch F is formed between its concave faces f f with a flat projecting face, 1, arranged directly above the anvil or face Z.

Before being placed between the curved faces of the dies the equalizer is forged between the flat faces If to the form shown in Fig. 9, being a straight bar provided at its ends with enlargements or fillets i i and opposite the point where the abrupt curve is formed with a knee or enlargement, j. The inner edges of the filletsi i are beveled or inclined, as shown in Fig. 9, so that when the feet I) b are bent into the position shown in Fig. 10 said inclined edges will form a continuation of the upper horizontal edges of the foot and stand parallel with the body A of the equalizer. The punch and lower die are provided in their adjacent faces, between the concave and convex faces d e f f and in rear of the flat faces Z Z, with an opening or recess, m, which enables the punch to clear the inner end of the equalizer when the same is placed between the faces Z Z. When the equalizer has been forged to the form shown in Fig. 9, the end of the bar, which is to have the short curve and the long foot I), is placed upon the top of the short convex face 6 of the lower die,the proper position of the bar being determined by marking the same or by means of a gage. The flat face 5 of the punch,striking the foot Z),gradually bends the unsupported portion of the bar against the convex face 6 and forms the leg a, and the outer end of the foot,striking the bot tom of the recess 6, is gradually bent upwardly at an angle to the log 11 until it is squarely seated in said recess. When the leg and foot have been thus bent, the concave facef of the punch strikes the upper edge of the leg a and finishes the bending of the same. The opposite end of the bar, having the short foot b, is then placed upon the top of the long convex face (1, and the leg a and its foot are bent in a similar manner.

WVith my improved dies the equalizers can be produced in much less time than heretofore and by a single heating, and they are more highly finished and rendered more uniform than by making them by hand, as hitherto practiced.

It is obvious that the dies may be divided between the short and long convex and concave faces d e ff and the dies be attached to separate hammers,in which case one end of the equalizer is forged upon one hammer and the other end upon the other hammer; but I prefer to use the double die shown in the drawings.

WVhen both ends of the equalizer are constructed alike, with feet of the same size and with legs having similar curvatures, only one die is necessary.

I claim as my invention 1. The combination, with the lower dieprovided with a convex face and a rectangular recess or depression arranged at the base of said convex face,of a punch or upper die provided with a concave face corresponding tothe convex face of the lower die and with a fiat working-face arranged above said rectangular recess, substantially as set forth.

2. The combination, with the lower die, 0, provided with short and long convex faces d 6, short and long rectangular recesses or depressions c d, arranged at the lower ends of said convex faces, and with an anvil or flat face, Z, arranged between said convex faces, of the punch or upper die, F, provided with short and long concave faces ff, corresponding to the convex faces of the lower die,fiat workingfaces 9 g,arranged at the base of said concave faces above the recesses of the lower die, a flat face, Z, arranged between said concave faces above the anvilZ of the lower die, and a recess or opening,m,formed in the adjacent faces of the upper and lower diesin rear of the faces Z Z, substantially as set forth.

W'itncss my hand this 19th day of May,1888.

JAMES REILLEY.
