THOMAS L; MOKEEN, OE EASTON, PENNSYLVANIA.

CAR-COUPLING.

SPECIFICATION forming par of Letters Patent No. 325,847, dated September 8, 1885.

Application filed February 19, 18E5. (No model.)

To all whom it may concern:

Be it known that I, THOMAS L. MOKEEN, of Easton, in the county of Northampton and State of Pennsylvania, have invented a new K part of one of my improved car-couplings. Fig.

2 is a side elevation of the other. part of the coupling, part being broken away. Fig. 3 is a sectional plan view of a part of the coupling, taken through the line as x, Fig.1. Fig. 4 is a plan view of the other part of the coupling, part being broken away and the coupling'pin being shown in section. Fig. 5 is a front elevation of one part of the coupling. Fig. 6 is a sectional front elevation of the same, taken through the line y y, Fig. 1.

The object of this invention is to improve the construction of the cancouplings for which Letters Patent Nos. 301,737 and 301,788 were issued to me July 8, 1884, in such a manner as to make them simpler in construction, more convenient in use, and more reliable in operation.

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

A represents the draw-bars, which are made with open sides and with perforations in their rear ends for the passage of the draw-rods B. Each draw-rod B is designed to be provided with aspring or springs in the ordinary manner, to lessen the jar in starting and stopping, and is also designed to be secured to the frame of the car-body by keys or other suitable means. The draw-rod B, at a little distance from its forward end, is provided with ahead, 0, which rests against the forward side of the rear end of the draw-bar A, and thus sustains the draftstrain.

The projecting forward end of the draw-rod B serves as a guide to the rear end of thespiral spring D, placed within the draw-bar A, and

the rear end of which rests against the head 0 of the said draw-rod. The forward end of the spiral spring D rests against therear sideof the follower E, and is kept in place by a p1n, F, formed upon thesaid rea'rside of the follower. The top and bottom of the follower E are provided with grooves E, to receive the guide or guides G, placed Within or cast solid with the draw'bar A, so that the follower will be wholly within the draw-bar, and will thus be protected from accidental injury.

The rear end or bend of the guide G, when made in one piece and separate from the drawbar, is perforated to receive the head 0 of the draw-bar B, so that the said rear end will be held securely in place.

The forward end of the lower guide G rests in a recess, H, in the rear end or shoulder of the link-block I, formed upon or attached to the bottom of the forward part of the drawbar A. The said block I limits the forward movement of the follower and prevents it from coming in contact with the coupling-pin M.

In the forward side of the follower E 18 formed a recess, J, to receive and center the end of the coupling-link K as it enters the draw-head. The follower E, when in its normal position, projects a little beyond the end of theupper guides G, so that the stud or pin L, attached to or formed upon the rear side of the lower end of the coupling-pin M, will project into the upper groove'of the follower to support the said coupling; pin when raised above the link K. The projection L also serves as a stop to prevent the coupling-pin M from being raised out of the draw-bar acoldentally. The coupling-pin M is inserted in a hole, N, formed through the'upper and lower parts of the drawbar A.

In the rear side of the lower part of the hole N is formed a groove, 0, to receive the projection L when the coupling-pin M is lowered.

In the forward side of the upper part of the holeN is formed a tapered or V shaped groove, P, to receive a correspondingly-shaped projection, Q, formed upon the forward side of the coupling-pin M, to prevent the said pm from turning. The projection Q terminates at such a distance above the projection L that when the coupling-pin M is raised to bring the said projection L close to the lower surface of the upper part of the draw-bar A the lower end of the projection Q will be above the upper surface of the said upper part of the drawbar, so that by turning the couplingpin M partly around the lower end of the said pro jection Q will rest upon the top of the drawbar, and the said pin cannot be made to drop by a jar, and the cars can be run together without coupling.

\Vhen the cars are to be allowed to couple as they are run together, the pin M is turned to bring the projection Q over the groove I, and the said pin is lowered until the projection L comes in contact with the top of the follower and stops and supports the couplingpin until the said follower E is'pushed back by the impact of the end of the entering link K, which allows the pin M to drop into place throughthe said link, coupling the cars.

The upper side of the link-block I is inclined, to guide the link K into place when entering the draw-bar from the draw'bar of a higher car. The rear part of the link-block I is perforated transversely to receive the bolt R, to which are attached the ends of the linklifter S, the middle part of which rests in a groove at the forward end of the li-nkblock I, so that it cannot be struck by the link K when entering the drawbar, and will be out of contact with the said link when the cars are coupled.

One end of the bolt R is bent forward to form a crank-arm, 'I, which is connected with and operates by the system of levers shown and described in Letters Patent Nos. 301,737 and 301,738, to raise the link-lifter into contact with the link K, to guide the said link into the draw-bar of an adjacent car when the czars are to be coupled.

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

1. In a car-coupling, the combination, with the draw-head A, having the removable longitudinal guides G, of the follower E, having grooves E in its upper and lower faces, substantially as herein shown and described.

2. In a car-coupling, the combination, with the draw-head A, having the guides G, of the spring-pressed follower E, having grooves E, and projecting beyond the end of the upper guide, and the coupling-pin M, provided with the pin or stud L, substantially as herein shown and described. v

3. Theincliued link-block I, secured to the draw-bar in front of the follower E, to guide the link and carry and protect the link-lifter S, as set forth.

4. The link-lifter S, in combination with the link-block I, as shown and described.
