CAR-COUPLING.

SPECIFICATION forming' part of Letters Patent No. 663,640, dated December lll 1900 Application tied June 14. 1900. saranno. 20.317. lNomodel-J To a/ZZ whom t may concern:

Be it known that I, WILLARD F. RICHARDS, a citizen ofthe United States, residing at Buffalo, in the county of Erie and State of New York, have in vented new and useful Improvements in Gar-Couplings, of which the following is a specication.

This invention relates to that class of twinjaw carcouplings having a horizontallyswinging jaw or knuckle and a horizontally-swinging lock, commonly known as the Gould lock, and a spring which holds the lock in engagement with the tailpiece of the knuckle, and more especially to an improvement in the coupler of this class shown andl described in Letters Patent of the United States No.,584,893, granted to me June 22,

detached side elevation of the abutment ofthe lock-spring. Fig. 5 is a top plan view thereof. Fig. 6 is a transverse section in line 6, Fig. l, the thrust-rod, spring, and bearing-block being omitted.

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

A is the chambered draw-head of ordinary construction, and A the hollow draw-bar.

B is the knuckle, C the horizontally-swinging lock mounted on the vertical pivot c, and D D' are the customary inclines arranged in the draw-head above and below the lock for swinging the same backward when raised and forward when released.

E is the link which connects the lock with the usual operating devices and which are not shown in the drawings.

F is the thrust-rod arranged in the drawhead and the draw-bar and having its front end connected with the free end of the lock,

preferably by engaged eyes f f, arranged on these parts, as shown, so as to form a swiveling connection, which permits the thrust-rod to freely follow the combined vertical and horizontal movements of the lock. The rear portion of this thrustrod is guided. in a hollow longitudinal abutment or abutmentsocket G, which is removably arranged in the draw-bar and provided in its closed rear end with an opening g, through which the thrustrod passes. This abutment-socket is flared forwardly and its axis is arranged somewhat obliquely to the draw-bar to permit the necessary vertical and lateral movements of the thrustrod. The abutment-socket is held against rearward displacement in the drawbar by an internal stop or lug h, which is arranged at the top of the draw-bar and against which a shoulder Zz at the rear end of said socket abuts. The abutment-socket is flat at its top and on one of its sides, and these dat surfaces bear against the top and the lcorresponding side wall ofthe hollow draw-bar, as shown in Fig. 6. The abutment-socket is held in this position by a shoulder t', formed at its top and bearing against or engaging behind an internal longitudinal iiange or rib t, arranged on the upper portion of the drawbar, and by a longitudinal langej, formed on the lower portion of the abutment-socket adjacent to its flat side and engaging behind a similar rib or ange j', which projects upwardly from the bottom of the draw-bar. The anges t" and j of the draw-bar, While eonning the abutment-socket against lateral displacement, permit the same to be conveniently slid rearwardly into place against the stop-lock 7i or to be withdrawn forwardly from the draw-bar.

K is the lock-spring surrounding the thrustrod and bearing at its front end against a washer Zo, which in turn abuts against the eye f of the rod and at its rear end against the front end of a bearing block or sleeve Z, Which in turn bears against the closed rear end of the abutment-socket. The thrust-rod slides freely through the bearing-block Z, and the latter is provided with a convex rear end Z', which bears against the concave bottom or rear end of the abutment-socket G, thereby permitting the rear portion of the thrust-rod IOO to rock or swivel freely `in the abutmentsocket in adapting itself to the varying posi- -tions of the lock. As shown in Fig. 3, the

bearing-block is hollow, and the rear end of the spring bears against an internal shoulder m of said block.

As the abutment-socket is not secured in place by Cotter-pins or other separate fastenings, but is simply slid rearwardly into the guideway formed by the longitudinal ribs i j' and the opposing corner of the hollow drawbar, the socket can be readily inserted and removed without special care, and the cost of the coupler is also reduced.

I claim as my invention-- l. The combination with the draw-head, the hollow draw-bar, the knuckle and the lock, of a hollow abutment or socket removably seated in the draw-bar and flared toward the lock, a thrust-rod guided in said socket and connected with the lock, and a spring applied to said rod and tending to hold the same in engagement with the knuckle, substantially as set forth.

2. The combination with the draw-head, the knuckle and the lock, of the hollow draw-bar provided in its top and bottom with internal longitudinal retaining ribs or iianges, and in rear of said iange'swith a stop, an abutment arranged in the draw-bar and removably seated between said langes and the adjacent top and side walls of the draw-bar and abutting against said stop, athrust-rod connected with the lock and guided in said abutment, and a spring applied to saidfrod between the lock and said abutment, substantially as set forth.

3. The combination with the draw-head, the' hollow draw-bar, the knuckle and the lock; of a hollow forwardly-flaring abutment or socket removablyseated in the draw-bar and provided with a concave rear end, a bearingblock having a convex rear end which bears against the corresponding rear end of the abutment-socket, a thrust-rod connected with the lock and passing through said bearingblock and the rear end of the abutment'- socket, and a spring applied to said rod and abutting at its rear end against said bearing block, substantially as set forth.

Witness my hand this 3d day of May, 1900.

WILLARD F. RICHARDS.
