CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 328,928, dated October 27, 1885.

Application filed February 11, 1885. Serial No. 155,591. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM EMMETT, of Logansport, in the county of Cass and State of Indiana, have invented a new and Improved Oar-Coupling, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a sectional elevation showing a part of the frame of two cars, and showing one entire coupling and a part of another, the draw-heads being shown coupled together, and Fig. 2 is a front elevation of a part of the embody, the coupling and the levers attached to the body of the car for operating the coupling.

The invention will first be described in combination with the drawings, and then pointed out in the claims.

A A represent the draw-bars of my new car-coupling. These are each castin one solid piece of metal, with the shank a, couplinghead a, and weight a formed upon the lower side of the shank a. The coupling-heads a are each recessed, as shown at b, to form two opposite claws, c c, the metal of the drawhead being removed at the center to form a cavity, 12, between the claws c. The outer surfaces of the claws care rounded, as shown at c, Fig. 1, and the cavities between the claws c c are concaved, as shown at 0 Fig. 1, to form cams, so that when two cars having these couplings are brought together the action of the cams 0 upon the rounded surface a of the claws 0 will cause the draw-heads and drawbars of the two couplings to be slightly rotated in opposite directions, which will cause the claws c of the opposite draw-heads to engage each other, and thus efiect the coupling of the cars without the use of springs, pins, or other separate devices.

Each draw-bar A is attached to the body of the car by a keeper, B, and cross-timbers O 0, through an opening in which the rear end of the draw bar passes. A collar, a is formed upon the rear end of each draw-bar to cause it to be held by the timbers O, and each draw-bar is recessed, as shown at d, to receive the anti-friction ball 6. A plate or cross-bar,

D, presses against the ball 6, being held forced forward by the heavy coiled spring E, which is attach ed to the heavy timber F and to the said bar D, by'being placed upon the corresponding projections, f, so that the spring E serves as a buffer to the car.

The cars being coupled, in order to uncouple them it is necessary to partially rotate one or the other of the draw-bars A, so as to disengage the claws c, and this may be ac complished from the top or platform of the car by the lever G, which is bent and fulcrumed at g, and acts at its lower end against a shoulder formed in the draw-head by the recess g,- or it may be accomplished from the ground at the side of the car by the lever H, which is bent and fulcrumed at h, and acts at its bent end against a shoulder formed by recessing the draw-head at h. By pressing the outer end, of the lever H downward the bent end of the said lever will turn the draw-head A, and movement of the upper end of the lever G in the direction of the arrow will have the same effect, and the rotation of the drawbar will swing the weight a, from the center, so that as soon as pressure applied by either of the levers is removed the weight will act to bring the draw-head back to its original positionthe position it must occupy when the cars are backed together for coupling.

In bumping-that is, switching or moving cars about a depot-one of the draw-bars should be turned and held somewhat out of its natural position, so that the rounded ends 0 of the draw-heads will abut, thus preventing the cars from coupling.

In coupling it will be understood that it is only necessary to back the cars together, whereupon the claws c of one draw-head will enter between the claws of the other, and the rounded surfaces 0 of each draw-head will strike the concaved surface I) of the other, which will cause the draw-heads to rotate slightly in opposite direction to cause the claws c of the opposite draw heads to engage with each other, as shown clearly in Fig. 1.

Constructed as described, it will be seen that the draw-bars and draw-heads are made entire in one solid piece of metal, that they may be cast without a core and used without special fitting, and that no springs save the 2. The draw-bar formed with a, weight, a in combination with the draw-head 11, having 1 5 recesses g h, and operating-levers G H, the draw-head being formed with the claws 0, substantially as described.

3. The draw-bar formed with the recess (1, in combination with the ball 6, plate D, and 20 buffer and spring E, arranged substantially as and for the purposes set forth.
