IMPROVEMENT -IN CAR-(.'OUPLINGSl The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE H. IVEEKS, of Alle gan, in the county of Allegan and State of Michigan, have invented a new and useful Improvement in Gar-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part oi' this specification, in which- A Figure l is a vertical longitudinal section of my improved car-coupling .taken through the line a; x, fig. 2.

Figure 2 is a top view of the same.

Figure 3 is a detail section vtaken through the line y r, 1-

Similar letters of reference indicate corresponding parts. L

My invention has for its object to furnish a simple, strong, durable, and effective car-coupling, which shall be so constructed as to couple the cars antomatically as they are run togetherLand which may be easily and conveniently uncoupled; and

It consists in the construction and combination of the various parts of the coupling, as hereinafter more fully described.

A represents the bumper-head, which may be eonstructed and secured to the body of the car, in the ordinary manner.

llhe mouth of the bumper-head A is made hoppershaped, in the ordinary manner, and the inner part of its cavity is enlarged to form shoulders to receive and support the bars B.

The bars B are pivoted at the outer edges of their ends to the upper and ylower parts of the bumperhead A, as shown in tigsil, 2, and 3, in such positions that their inner edgesmay meet or nearly meet when the said bars are swung into the position shown in g. 3, in which position their ends and the outer parts oi' their forward sides rest against the solid shouldersof the bumper-head A.

` Upon the inner parts of the upper ends of the bars B are formed pivots or arms b1, which project through an opening in the upper part of the bumper-head A, and through inclined slots in the plate O, which slides upon the top of the bumper A, and the edges ot' which cntcr and work in groovcd flanges a formed upon or attached to said top. y

Upon the rear edge of the slide C is formed, or to it is attached a guide-pin, D, which passes through a guide-hole in a flange or keeper, a2, formed upon or attached to the top of the bumper A.

Around t-he arm or pin I) is coiled a'wire-spring, E, the forward end of which rests against the rear edge oi' the 'plate or slide 0,'and the rear end 4of which rests against the tlange ai.

In the upper and lower part of the inner edges of the bars B are formed semi-conical not-ches b2 to rel ceive -the coupling-bar F, which `is made with a conical head upon each end.

By this construction, when the cars are run to gether, the conical head of the bar F will enter the upper or lower conical recess b2 in the edgesof the hars B, and force the inner edges of the said bar s back until the head of the bar F has passed the said edges, when the spring E will force the slide C back, the inclined sides ot' the slots of which press against the pins b1 of the bars B, and thus force said bars back to their places, when the draft-strain will be sustained by the shoulders oi' the heads of the bar F resting' against the inner sides oi' the bars B, as shown in iig. 2. v i

By forcing the slide C back, the inclined sides'of its slots pressing against the pins b force back the inner edges of the bars B, releasing the bar F and uncoupling the cars.

G is a lever, the end of which is pivoted to a support attached to the top of the bumper A, and which is connected with the slideC by a rod or chain, H, so that, by operating the lever G, the slide C may be easily and conveniently drawn back to uncouple the cars. v

Having thus'described my invention,

I claim as new and desire to secure by Letters Iatent- 1. The pivoted bars B, having semi-conical notches formed in their adjacentedges, slide C having inclined slots formed in it. guidepi n D, and spring E, in combination with each other and with 'the bumper B, substantially as herein shown and described, and for the purpose set forth.

2. The combination ofthe lever G and connect-ing- Iod or chain H with the spring E, guide-pin D,slotted slide C, pivoted and notched bars and bumper A, substantially as herein shown and described, and for the purpose set forth.

GEORGE H. WEEKS. IVitnesses:
