CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 377,841, dated February 14, 1888. Application filed November 29, 1887. Serial No. 256,465. (No model.)

ranged that it can be made not to couple.

It is simple, durable, and reliable at all times.

Figure 1 is a perspective view of the drawhead. Fig. 2 is a view of the movable appliance to fit in the draw-head for holding thetwo books of the two draw-heads together to keep from uncoupling, also to effect uncoupling.

- prong or arm d, which extends beyond the The draw-head consists of, first, a hook, A,

by which the coupling is made with the hookv in the opposite draw-head; second, a guard, B, (a solid part of the draw-head,).by means of which the entering hook is guided into position for coupling. It is curved where the entering hook strikes it, so as to guide or force this hook into a'position for coupling.

This guard and stem of the hook are provided with a recess or opening, a, in which the movable appliance O is inserted, except the guard. The back of this prong, when open for coupling, fits up against the guard, and the outer edge of the inner prong is even with the book. The incoming hook strikes the long prong, glides along and strikes the curved surface of the guard, and forced against the inner prong, driving it back into the recess, when it meets its companion hook. As

the inner prong is forced into the recess the outer prong is brought into position to prevent uncoupling. This movable appliance is loosely pivoted to the draw-head at e.

h is a hinge-like appliance. One end is loosely pivoted to the end of the longer prong,

d. Near the other end it is pivoted to the guard at f. This hinge has a spring attachment, 9. One end is riveted to the front .end of the hinge, the other end movable and working into the connecting part of the hinge in such a manner as to spring the hinge straight when the entering hook is forced into position for coupling, thus, as it were, locking it and preventing uncoupling. The

handle or lever h, (part of the hinge,) extending back from the guard, is forthe purpose of uncoupling. the middle of the hinge proper is forced outward, the outer prong is drawn back, and

By forcing this handle inward at the same time the inner prong presses the car, which lever is pivoted to the car-near the middle of the car, so that by raising one end of this lever the uncoupling takes place. By lowering or forcing downward the other end of the lever the uncoupling takes place. A chain or iron rod extending. from the end of the lever to be raised to the top of the car will enable the brakemanto uncouple when on top of the car.

To prevent coupling, a bolt is placed in an opening in the draw-head back of the movable appliance i.

The hook may be provided with an opening to admit a link from a link-coupler and fastened with a pin dropped through the perpendicular hole.
