JOHN H. B. MCCRAY, OF BLOSSOM PRAIRIE, TEXAS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 243,284, dated June 21, 188,1.

Application tiled October 14, 1880.

To all whom it may concern:

Be it known that I, JOHN H. B. MCGRAY, of Blossom Prairie, in the countyl of Lamar and State of Texas, have invented a new and Improved Oar-Ooupler, of which the following is a specification.

This invention relates to that class of coup- Iers that are self-couplers and it consists of an open-top hook-shaped draw-bar provided with a pivoted T-shaped vertically-moving coupling-bar, and provided also with an end socket for using the ordinary coupling link.

Figure l is a side elevation representing two couplers in coupling position, one of thernrbeing in section on line x, Fig. 2. Fig. 2 is a plan of the same. Fig. 3 is a front elevation of a coupler.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a draw-bar, having in its top a longitudinal opening, a, in the rear part of which a T-shaped couplingbar, B, is pivoted on a transverse pin, b, so that the free T end of said bar B shall extend in front of the said draw-bar A, for coupling in an opposite draw-bar A, vthe cross-bar d 0f the said T end being beveled on both front edges, as shown in Fig. 1, so that should two draw-bars come in co'ntact with each other the)T will at once slip over each other, and so that on the contact of' one with the face of a draw-bar said coupling-bar B will at once slide up over the outer curve, h, of the hook end of (Model.)

said draw-bar A. The top of said draW-barA is fashioned in the shape of a hook, with the barbs c c pointing rearward, so that when two draw-bars, A A, approach for coupling, the T end of one coupling-bar B will strike the face ot' the opposite draw-bar A, and slide up over the curve thereof and over the barbs c c, and be caught and held inthe bend of the hook, as shown in Fig. l, while the other coupling-bar B will override the lower and coupled bar, B, and rest thereon, as shown in Fig. 1. couple, the bars B are lifted or swung upward by means of the attached staples and chain E, oI any other suitable device.

The draw-bars Aare also provided with horizontal sockets f f and vertical coupling-pin holes g g, for the use of the usual coupling link and pin whenever desired.

. By the use of this device the danger to life and limb incident upon going between cars for coupling may be avoided.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A car-coupler constructed substantially as herein shown and described, consisting of drawbar A, provided with curved face 7L, hookscc, and vertically-swirl ging T-shaped couplingbar B, as set forth.
