IMPROVED GAR-COUPLING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. H. CLARK, of Fond du Lac, in the county'of'Fond du Lac, and Stateof Wisconsin, have invented a new and improved Self-Acting Cabcoupler; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had t0.the accompanying drawings forming a part of this specification, in which- Figure 1 is a longitudinal section of two railroad car draw-heads in position for connection with the carcouplers of my invention, taken in the line a: m, fig. 2.

Figure 2 is a-top view of a single draw-head with my car-coupler attached.

Figure 3 is a front view of my car-coupler detached.

Figure 4 is a side view detached.

Similar letters of reference indicate like parts.

This invention relates to a self-acting device for coupling railroad cars, which is very simple, strong, and sure in its. operation.

A A represent ordinary iron belt-mouthed car draw-heads or hunters, each of which has a square cavity opening into it from the upper side for receiving a nicely fitted sliding iron block, a, on the under side of which is pivoted a solid hinge-flap, 6, made to hang flush with the front side of the block a when open, and to double up against its bottom when pressed back by the shackle or link a, as shown at fig. '1. In the front side of the block a is a vertical groove for receiving a coupling-pin, d, the lower. end of which rests upon the top of the hinge-flap b when the flap hangs down, as shown at figs. 3 and 4, and the upper end of which is attached by a link to a chain, e, which is connected with theblock a for lifting it as required, for coupling and uncoupling. The chain e is designed to he usedbn freight ears for uncoupling them from the top. Long and narrow vertical recessesf are cut in the opposite sides of the block a, as seen in fig. 4, and set-screws g 9 pass through the opposite sides of the drawhead A, the ends of which screws project intothese recesses and prevent the block from coming out of the draw-head, while at the same time it can slide up and down freely. A hole, h, is made in the'draw-head to receive the end of the coupling-pin 11 when it drops in place to hold the link a, as shown in fig. 1.

For coupling cars the device is set by introducing the l-ink'c'behiud the coupling-pin d in the draw-head, when the hinge-flap b will be pushed back and rest upon the rear; end of the link, and the weight of the block a bearing upon it will hold the link level, as shown at fig. 1, while in the opposite draw-head the device will be set by allowing the hinge-flap b to hang down straight and rest upon the opening or mouth of the draw-head; the coupling-pin dwill then be held up by the flap. When in this position the draw-heads are brought together, the free end of the link 0 will be pushed against the hinge-flap b, and force it back so that the pin (2 will fall of itself and catch-in the link, and thus by automatic action will complete the coupling of the cars: to which the draw-heads are attached. i l

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

The combination of the sliding-block a, the hinge-flap b, and the coupling-pin dwitli a draw-head. on a railroad'car, constructed and operating substantially as and for the purposes herein described.
