DRAWBAR-SPRING POCKET.

SPECIFICATION forming part Of Letters Patent No. 497,825, dated May 23, 1893.

Application tiled January 31, 1893.

To @ZZ ttf/tom t may concern:

Be it known that I, CHARLES T. SeHoEN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Drawbar-Spring Pockets, of which the following is a full, clear, and exact description.

The object of this invention is to provide drawbar rigging for use in connection with a yoke applied to the d rawbarinstead of a drawbar rod, both modes of connection being in common use.

In practicing my invention, I employ guideplates, struck up from wrought metal, preferably steel plate, which are supplied with top and bottom detachable iianges, and combined with novel followers which are made with teats to center the springs, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is a top plan View and half-section, the section being taken in the plane of line -m, Fig. 3. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is across section, taken in the plane of line y-y, Fig. l; and Fig. 4. shows, in front view and edge view, the follower detached.

The draw timbers a, drawbar b, springs c, d, and yoke e are of usual construction. Each guide-plate f is made with transverse endlianges f', and a central transverse bead, f2, which are let into recesses made in the drafttimbers or sills, and are also provided with the abutments f3 near their opposite ends. These abutments f3 are substantially right angular in cross section, so as to present opposite dat surfaces to receive the followers g, hereinafterdescribed. The abutmentsf3,be ing hollow, are adapted to receive bolts h, by which flange plates z' are applied to the longitudinal edges, at top and bottom, of t-he guide-plates; said Iianges serving to retain the followers and springs in the drawbar The guide-plates, provided with the features hereinabove described, may be very readily struck up or pressed from steel plate in dies,

and at very small cost.

Serial No. 460,407. (No model.)

The followers g are made, by preference, of wrought metal, say steel plate, aud each is provided with a mediate teat g', which is of little less diameter than the inside diameter of the inside coiled spring d, and thereby the nest of springs is centered within the drawbar pocket and prevented from displacement, no matter what the distance between the draw timbers may be. The teats g maybe formed upon the followers by punching or drawing up the metal in any suitable and well-known manner. There is no perforation, therefore, of thefollower, and, consequently, the strength of the said follower is not reduced, but, in point of fact, its strength is rather reinforced or increased by virtue of the provision of the central teat.

The guide-plates supplied with the flange plates, substantially as described, are applied to the draw timbers by means of the transverse bolts, j, 7n, and it will be observed that the transverse beads f2 receive within them and thus countersink the heads of the bolts 7c. The yoke e and the drawbar I9 are applied to the follower-plates in the drawbar pocket substantially as shown more especially in Fig. 2, so that the yoke will bear against the rearmost follower and the drawbar against the forward follower, and thereby the action of the springs obtained. The abutments f3 limit the movements of the followers in both directions. Inasmuch as the outer ends of the abutments are at an incline, they serve to brace and stiften the said abutments against the thrust of the followers as they are moved by the drawbar in the operation of the car. The end flanges f and beadsf2 entering into the draft timbers substantially as shown, a large measure of the strain on the drawbar pocket is transmitted to such draw timbers.

While I have specially designed my improvements in drawbar spring pockets for manufacture from sheet or plate metal, by die-pressing or equivalent manufacture, yet I do not wish to be underetood as limiting my invention to that mode of manufacture, inasmuch as the parts of the drawbar spring pocket may be produced in any other way.

My guide-plates differ from those shown in my patent No. 426,143, dated April 22, 1890, in several particulars, among which are that the longitudinal ianges in this present in- ICC vention are attachments to and not integral with the guide-plate proper; and, also, that the ends of the guide-plates used to receive the boltsj are made fiat for that purpose, instead of being provided with recesses, as in the patent referred to.

1. A guide-plate for drawbar spring pockets, having hollow abutments near its ends, and longitudinal flange plates applied to such guide-plates by bolts passed transversely through said hollow abutment's, substantially as described.

2. A guide-plate for drawbar spring pockets, having transverse end-flanges and a trans verse bead projecting from one side, and transverse hollow abutments projecting from the opposite side near the ends of the guideplate, all formed in a single piece of wrought metal, such as plate steel, and pressed to shape, combined with longitudinal flangeplates and bolts arranged in the hollow abutments and connecting the flange-plates =with the guide-plate, substantially as described.

3. In a drawbar-spring pocket for use in and the ange-plates, and followers having4 integral spring-centering teats, substantially as described.

In testimony whereof I have hereunto set my hand this 28th day of January, A. D. 1893. 45
