VILLIAM HENRY VRIGLEY, OF NEW ORLEANS, LOUISIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 375,973, dated January 3, 1888.

Application filed July 22, 1887. Serial No. 245,027. (No model.) A

To aZZ whom, it may concern/.- Be it known 'that I, WILLIAM HENRY WRIGLEY, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Car-Couplings, of which the following'is a specification. My invention relates to car-couplers which employ an ordinary link, and a tilting pin which will be automatically lifted at its lower end to fall into the link, and which maybe lifted out of the Way of the link by suitable means when the cars are to be unconpled.

My improvement consists in certain constructions and combinations of parts hereinafter described, and particularly*designated in the claims.

In the accompanying drawings, Figure l is a side elevation partly in section. Fig. 2 is an end view in section; and Fig. 3, a side view, also in section, showing the,pin raised.

The draw-head A is secured to the end of the draw-bar B in the usual way. The bottom ofthe draw-head A has a slot, a, through which the lower end of the coupling-pin C passes, and against the forward end of which the said coupling-pin is held when the link is pulling against the pin. The top of the drawhead has a slot, a', through which the upper end of the pin C passes, and also has lugs a2 upon opposite sides of said slot, between which the upper end of said coupling-pin is supported, and through which a bolt, D, passes to support the coupling-pin C, and provide a fnlcrum upon which said pin may swing or be tilted. The bolt D has a head, d, at one end and a slot and split pin, d', at the other` end,which hold itsecurely in place upon the draw-head and within a slot, c', in the upper end of the coupling-pin. The slot c runs lengthwise of the pin C at the upper end thereof, and has an enlarged baekwardly-extending aperture or recess, c2, at the upper end thereof, into whichthe bolt D will rest when the pin C is not otherwise supported, and will at such time obstruct the upward movement of the pin C and prevent it from beingV joltedout of its seat within the link, when the cars `are in motion, by any ordinary jars or The lower end of the pin G is weighted sufficiently to hold it in a vertical position, and to cause it to fall or restore itself to its vertical position after it has beeny tilted or lifted A(1t-its lower end by the link in the act of coupling itself therewith.

The rear or back portion of the bottom of the draw-head has a pocket, a3, into which the end of the link I passes to support said link` in a horizontal position ready for insertion into the coupling draw-head of the adjacent car.

The upper end of the coupling-pin C is connected by a bolt, E, having a head, e, and split pin e', with a bifureated link, F, the arms ff of which embrace the opposite sides of the upper end of the pin C, and the arm f of which is connected by a riveted pin, f2, with the lower end of an upright bar or lever, Gr.` The lever G is passed through and is supported at or near its upper end in the slot hof a plate, H, bolted to the end of the car, by means of which the pin C may be either lifted vertically or be tilted baekwardly at its lower end, with the bolt E asa fulcrum, to release thelink I and permit the cars to be uncoupled.

From the foregoing it is manifest that the pin C may be easily lifted out of the link or tilted to permit the link to be withdrawn from the drawhead when desired, the pin will be ordinarilyT held in its seat in both the upper and lower slots ofthe draw-head bythe weight of the pin and by the enlargement of the upper end of the slot formed in said pin, and the link is held in ahorizontal position by the pocket at the rear of the draw-head.

I claim as my invention and desire to secure by Letters Patent 1. In a car-coupling, the combination, with the draw-head A, of the fulcrum-bolt D, link I, and a eoupling--pinLQ having a slot, c', enlarged and extending backwardly to hold the pin from jolting out of place, and means for both lifting and tilting the said couplingpin, substantially as described.

2. In a car-eoupling, the combination, with the draw-head A, of the fulcrunl-bolt D, link I, coupling-pin C, slotted at its upper end, link F, lever G, and plate H, substantially as de scribed.

WILLIAM HENRY VVRIGLEY.
