IMPROVEMENT iN cAR-couPLlNGs.

Specication forming part of Letters Patent No. 182, [14, `dated September 12, 1876',5 application tiled July l, 1876.

lowing is a specification:

In the accompanying drawing,Figure l represents a vertical longitudinal section of my improved car-coupling. Fig. 2 is a top view, Fig. 3 an end view, and Fig. 4 a detail top view, of coupling-hook as pivoted to draw? bar. t

Similar letters of reference indicate correspondin g parts.

My invention relates to an improved automatic car-coupling for passenger and freight cars, which may be coupled with cars having the common pin-and-link coupling, and which combines a buffer arrangement with the drawhead and coupling.

c The invention consists of a spring-acte drawhead, with interior separately-movable draw-bar, to which a coupling spring-hook is pivoted. The draw-head has a top shoulder or projection that comes in contact with an auxiliary spring-bolt, and acts as butl'erhead thereby.

In the drawing, A represents a draw-bar of the usual construction, which is guided in longitudinal direction on the bottom iframel of the car, and placed in connection with a strong spiral spring; B, by aseparatelysliding drawbar, C, that extends through the rear end of the draw-head. The draw-bar C acts by a cross-pin or fastening, A, and cross-plate b on the spring B, when pulled in forward direction, being' stopped by a lateral guard-piece, d, in opposite direction. The draw-head A is, by its connection with the draw-bar G,readily drawn in forward direction; but also carried back independently of the draw-bar, which retains its position, when, by the concussion of the draw-heads, in coupling,the rear end of the draw-head is pushed back, acting by a lateral plate, b', onfthe spiral spring B. The lateral plates b b are guided in side recesses of the car-frame, and serve to transmit the motion of both draw-head and draw-bar to the spring. The coupling-hook D is pivoted to the front or soeketend of draw-bar C, so as to swing in horizontal direction Within, the draw-head being -pressed sidewise by a bandspring, e, to interlock with the coupling-hook of the approaching car when the same enters the draw-head. The draw-head A is provided with top and bottom holes to couple with the common link and pin, the link being inserted above or below the coupling-hook, and the pin then dropped in the usual manner.v

The coupling-hook D is uncoupled by means of a hand-wheel, ratchet, pawl, and rope connection with the hook, as shown in Figs. l and 2, or by means ot'4 rope or chain and bellcrank lever, as shown in Fig. 3, either from the platform, top, or side ot' the car, as desired.

The top part of the draw-head Ais provided with a raised shoulder, f, that is in contact with aslidin g and guided spring-bolt, E, which serves to impart greater power of resistance to the draw-head, so that the same acts in the nature of a buffer by means of the auxiliary spring-bolt.

The cars, with my coupling,may be coupled or uncoupled on any curve,and produce the steady motion, as there will be no jerking of the hooks, as the buffer-springs are tightly compressed and hold the hooks tightly togethcr, reducing thereby the wear to a minimum.

The draw-head may be made either with closed or open sides, as desired, it serving mainly as a buffer, and for coupling with the common coupling. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y The draw-bar of a car-coupling, provided with shoulder f and spring-bolt E, arranged substantially as and for the purpose specified.

SAMUEL HAMER.
