CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 437,900, dated October 7, 1890.

Application filed June 12,1890, Serial No. 355,179. (No model.)

T0 all whom t may concern:

Be it known that I, HARLow F. CHAPIN, a citizen of the United States, residing at Brockport, in the county of Monroe and State of New York, have invented a new and useful Oar-Coupling, of which the following is a specification.

My invention is an improvement in carcouplings; and it resides in the novel structure, combination, and arrangement of parts, hereinafter fully described, and pointed out in the claims hereunto appended.

In the drawings illustrating my invention, forming a part of this specification, throughout which like letters of reference indicate corresponding parts, Figure l is a perspective view of the front and under sides of a car provided with my coupling. Fig. 2 is a vertical longitudinal section through the drawhead. Fig. 3 is a plan view of the draw-head.

In the drawings, A designates a car, having upon its under side the guides a, in which works the draw-bar B and the stop-plate a. Between the stop-plate a and the draw`head B', encircling the draw-bar B, is a coiled spring C, and on the other side of the stopplate a abutting it, fastened to the end of the draw-bar B, is another coiled spring O', surrounding the draw-bar. These two springs limit the movement of the draw-bar in either direction.

D is a rock-shaft extending across the end of the car below the draw-bar, having its ends provided with crank-handles d. Below the draw-head B the rock-shaft D has a curved arm d', which is used in a manner to be hereinafter described. At the side of the drawhead the rock-shaft D has another arm d2, which is connected by any suitable meanssuch as alink-connection-with a rod d3, which extends to the top of the car, moving vertically in guides or staples.

The draw-head Bis provided with a vertical longitudinal slot h, in which is pivoted the hook E. It also has a daring mouth Z9', and in the rear of this mouth b', forming the end of the slot b, are the faces b2 b3, beveled and curved, conforming to the front of the hook E, for a purpose to be described.

The hook E is pivoted on the shaft e, and is allowed a slight longitudinal movement thereon by the slot e. The head e2 of the hook extends above the draw-head to provide means whereby the coupling may be performed by hand should any of the parts be broken. The outer face of the hook E has its upper part e3 double beveled to correspond with the upper inner face b2 of the mouth b', against which it rests. From a point e4 the outer face of the hook slopes in a curve e5 downward and backward to the lower point e6 of the hook, and this curve e5 corresponds to the curve b3 of the mouth b. Above the point e6 the hook is recessed, as at e7, to provide a space for the link to rest in. rlfhe shoulder es limits its rearward movement. A flat spring e9 presses upon the upper face of the hook and keeps it in position. Two bolts elo and ell-one above and one below the hook E in the slot [2f-limit its movement.

The curved arm CZ of the rock-shaft D engages the side of the recess e7, and when the rock-shaft D is operated by its handles CZ or by the rod d3 the hook is raised to release the coupling-link F.

In operation when the link F strikes the curved face e5 of the hook E the pin is thrust backward and upward, the slot e allowing such movement until the link passes the lower point e6 of the hook, and, striking the shoulder e8, is caught in the recess e7 by the hook being pressed down by the spring e9. `When the draft is brought to bear upon the couplingby means of the hook E, the same is carried forward, its upper bevel e3 resting against the upper inner face of the mouth b', and its lower curve e5 resting against the lower inner face of the mouth. It will be seen that by this construction the greater the draft the rmer the link will be retained in place. It will also be evident that by the form of the recess e7 and the spring e pressing the hook .down-the link F will be held in a horizontal position ready for coupling with another car.

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

1. In a ear-coupling, the combination, with a draw-head provided with a vertical longitudinal opening and a flaring mouth, the rear of which has an inner upper double beveled face, of a hook pivoted in the draw-head, and

IOO

hav-ing a slotted connection with its operatin gshaft, the said hook having an outer face double beveled and provided with a rec-tangular recess e7 on the under side of the hook, 5 and the uncoupling-a rin d', mounted on a rockshaft and engaging the recess e7, substantially as and for the purpose described.

2. In a car-coupling, the combination, with a draw-head provided with a vertical longi- Io tadinal opening, of a hook pivoted in the draw-head and having a slotted connection with its operating-shaft, and provided with a rectangular recess e7 on the under side of the hook, and the uncoupling-arln d', mounted on a rock-shaft and engaging the recess e7, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
