DRAFT-HIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed Aprii 28, 1905. Serial No. 257,802`

Be it known that I, Jol-IN R. MITCHELL, a citizen of the United States, residing in Ohieago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draft-Riggingfor Railway-Cars, of which the following is a specification.

My invention relates to improvements in d raft-rigging for railway-cars.

My invention consists in providing' the side plates or stop-castings of the draft-rigging, near the front ends thereof, with a pair of grooves or recesses in combination with a V- shaped shim casting, the legs or limbs of which lit in the grooves in the upright side of the side plate or stop-casting and operating to limit the lateral or swinging movement of the draw-bar, so that the wear and abrasion incident to the draw-bar striking against the same may be taken by these V- shaped shim-castings, which may be removed and replaced when worn, thus greatly increasing' the life and durability of the side plates or stop-castings of the draft-rigging'. Then the shim-castings are inserted in the grooves of the side plates or stop-castings, they may be readily tightened or secured in place by blows or pressure thereon, which will operate to spread the legs of the shimcastings and tighten them in the grooves for the same in the stop-castings. Ordinarily, however, the lateral movement of the drawbar in striking against the shim-castings will itself serve to tighten them in place.

Mv invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure I is a side elevation,partly in section, of adraft-rigging. embodying my invention. Fig. 2 is a plan View, partly in horizontal section. Fig. 3 is a vertical cross-section on line 3 3 of Fig. 2. Fig. I is a detail perspective View of one of the V-shaped shim castings or plates, and Fig. 5 is a detail section on line 5 5 of Fig. 2. Fig.

6 is a detail perspective view showing the grooves in the upright face of the side plate to receive the shim-castings.

In the drawings, A A represent the center sills or draft-sills of a car to which the side plates or stop-castings are secured; A', the

rI he side plates or stop-castings D extend to the front of the car and are furnished with the customary stops or shoulders for the followers O to abut against.

E E are the springs of the d raft-rigging.

Each of the side plates or stop-castings D is provided near its front end with a pair of upright grooves or recesses (I in its upright front face d', this groove extending, preferably, to near the lower edge of the side plate or stop-casting, thus forminga stoporshoul- 7C der Z2 at the lower end of each upright groove or recess.

F F are a pair of removable or replaceable V-shaped shim castings or plates, preferably of malleable iron or steel or other bendable metal, the legs or limbsffof which lit in the upright grooves or recesses (il in the longitudinal upright faccof the sideplates or stop-castings D. 'Ihese V-shaped plates or castings FF, thus inserted on the side plates or 8O stop-castings D D, serve to limit the lateral or swinglng movement of the draw-bar and v receive the wear and abrasion incident thereindependently of the carry-iron and prevent the shim plates or castings from falling out when the carry-arm should through any cause be removed.

I. In a draft-rigging, the combination with the draw-bar, otl side plates or stop-castings provided each on its upright longitudinal face with a pair of upright grooves or recesses, and removable or replaceable V-shaped shim plates or castings fitting in said grooves or IOO recesses for the draw-bar to strike against in its lateral or swinging movement, substantially as speeiiicd.

2. In a draft-rigging, the combination with the draw-bar, of side plates or stop-castings extending to the front end of the car, and

All these 55 By having the up- 85 provided each with upright grooves in its longitudinal face and removable or replaceable V-sliaped sliims or bearing-pieces litting in said upright grooves or recesses, substantially as specified.

3. In a draft-rigging', the combination vvith the draw-bar, oi' side plates or stop-castings extending to tlie front end of the car` and provided each with upright grooves in its longitudinal face and removable or replaceable V-sliaped shims or bearing-pieces tting in said upright grooves or recesses, said upright grooves or recesses being closed or contracted at their lower ends to form stops or shoulders to prevent the V-sbaped shirns or bearing- JOHN R.
