DRAW-BAR-SPRING POCKET.

SPECIFICATION forming part of Letters Patent No. 426,148, dated April 22, 1890.

Application filed March 3, 1890.

To all whom, it may concern.-

Be it known that 1, CHARLES T. SCI-IOEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Draw- Bar-Spring Pockets, of which the following is a full, clear, and exact description.

The object of this invention is to simplify and eheapen the construction of the pockets for the draw-bar springs of railway-car couplings. In the master car-builders standard pocket there are some forty-eight bolts, straps, and castings, which render the device costly, complex, and unduly increase the dead-weight of the car, aside from the consideration of expense in time and labor in assembling. The use of pressed steel in making railway-car fittings, as illustrated in several patented inventions of mine which have gone largely into use, the increased servieeableness of such fittings, their great durability and lightness, coupled with. their faculty of interchangeability with the castnnetal fittings which they supersede, demonstrate the feasibility of the more extended use of this form of metal, and have led up to the present invention. It is proper to say here, however, that, broadly speaking, pressed-steel angle beams or plates have been applied to the draft-rigging in substitution of the ordinary oak draft timbers, and also that pressed-stecl pockets have been devised but these render necessary a reorganization of the draft-rigging, and this I purpose wholly to avoid.

The invention consists, then, in draw-bar guideplates for the pockets of railway drawbar springs constructed of pressed steel or other wrought metal, and so as to be interchangeable with the standards in common use, substantially in the manner hereinafter more particularly set forth and finally claimed.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a bottom plan. view, Fig. 2, a vertical sectional elevation, its plane being in the line at a of Fig. 1; and Fig. 3 is a vertical cross-sectional elevation of the ordinary master carbuilders standard arrangement of the draw bar timbers and springpocket, showing my Serial No. 342,385. (No model.)

guide plates substituted for those of the master car-builders standard. Fig. i is a perspective view of the guide-plate detached.

The longitudinal timbers (t and cross-timhers I), the springs c, and follower-plates (Z may be as usual.

In order to construct the guide-plates of pressed steel or the like so as exactly to replace or interchange with those used in the master ear-builders standard, and to adapt them to be applied without new bolts and new bolt-holes, I make each of the pairs of guideplates entering into the construction of a draw-barspring pocket of a single piece of plate-steel or equivalent wrought metal, as shown in detail especially in Fig. 4-that is to say, I take a piece or blank of the selected material, and by means of dies or other suitable tools, I form the cavity e, the bottom of which is to rest upon the timbers a, and this cavity terminates in shoulders f, against which the follower-plates (Z abut and form the drawbar stops, and then the ends g of the plate return to the plane of the bottom of the cavity and terminate in flanges 71, which are to be let into kerfs or grooves in the timbers a. 'The ends 9' receive the usual bolts i for securing the plates to the timbers. A rib j is projected from the bottom of the cavity, and it also is let into the timbers a. Flanges 7t extend the length of the longitudinal edges of the plate, and are made integral therewith. Thus the guide-plate is complete in one piece.

The configuration and size of the plate may be varied as may be required, and so, also, may be its mere details of structure. The flanges, ribs, and shoulders also serve to add strength and stiffness to the plate.

I prefer to make countersinks Z in the ends 9 to receive the heads of the bolts '5.

A guide-plate constructed in accordance with the principle of my invention is interchangeable as to size, bolt-holes, centers, &c., with present standards. Moreover it reduces the number of parts comprising a draw-barspring pocket from fortyeight in the present standard to twenty in mine. It is also very much stronger, more durable, less liable to displacement, and quite as cheap, if not cheaper.

\Vhat I claim 1. As an improved article of manufacture,

a guide-plate for draw-bar-sprin g pockets constructed for interchange with the castings and other parts forming the master car-builders standard and other common standards, and to be applied in the ordinary draft-ri ggin g, and comprising, essentially, a shouldered cavity to receive the ordinary spring followerplates, bolt-holes to receive the ordinary bolts 7 along the longitudinal edges, substantially as described.

4. A guide-plate for draW-bar-spring pockets, constructed of wrought metal, preferably steel plate, die-shaped, and having a shouldered cavity to receive the spring followerplates, a transverse rib at the bottom of the cavity, and ends provided with bolt-holes and longitudinal edge flanges, substantially as described.

5. A guide-plate for draw-bar-spring pockets, constructed of wrought metal, preferably steel plate, die-shaped, and having a shouldered cavity to receive the spring followerplates, a transverse rib at the bottom of the cavity, ends provided with bolt-holes, transverse end flanges, and longitudinal edge flanges, substantially as described.

In testimony whereof I have hereunto set my hand this 1st day of March, A. D. 1890.

CHARLES l. SCHOEN.
