UNITED STATES PATENT OFFICE.

HENRY o. BRADLEY, OF ,OAMDENPOINT, MISSOURI.

DAR-COUPLING.

SPEGIFIBATION forming part of Letters Patent No. 279,321, dated June 12, 1883.

Application filed April 19, 1883. (No model.)

To aZZ whom it may concern Be it known that I, HENRY O. BRADLEY, a citizen of the United States of America, residing at Camden Point, in the county of Platte and State of Missouri, have invented certain new. and useful Improvements in Oar-Couplings;-

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of this specification.

This invention relates to automatic car couplers, it object being to provide coupling devices of this class which. shall be strong and durable in construction, of few parts, reliable in operation, and not liable to get out of order.

The invention consists in certain novel constructions and combinations of parts, which will be hereinafter particularly described, and pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of two carcouplers constructed according to my invention, the coupling-pin of one being raised and that of the other low ered. Fig. 2 is a top view of the same. Fig. 3 is a front view of one of the couplers ap plied to a car. Fig. 4 is a perspective view of the shaft and wings, which are operated by the link to drop the coupling-pin.

The letter A indicates the draw-head, which is provided with three link-receiving compartments, b b b, arranged in vertical series, and having flaring outer open ends; These compartments are separated from each other by partitions c c, and through these partitions and the top and bottom walls of the draw-head are formed passages to receive a couplingpin, D. Through one side wall of the draw-head are formed elongated openings 0 c e, communicating with the link-receii'ing compartments, respectively. At the front ends of these openings 0 is a vertical shaft, F, mounted in suitable brackets, ff, and provided with projecting wings g 1 9, adapted to swing into the openings e c c and linlerceeiving com1: artments. To the upper'end of the shaft F is attached a projecting arm, 71, to which is connected one end of a chain, a, to the other end of which is attached a weight, It. The said .chain passes over a pulley, Z, and the weight draws the arm 72, so that it will swing the shaft F to carry the wings g g 9 into the link-receiving chambers and across the pin-openings when the coupling-pin is raised.

When the coupling-pin is raised it rests upon the top wing, and when the end of a coupling-link is forced into either of the chambers it strikes the wing g which is in said chamber and swings it outward, turning the shaft, and causing the other wings also to swing outward, and the top wing being thus withdrawnfrom under the coupling-pin, said pin falls through the link, no matter into which of the three chambers the link is forced.

Upon the top of the draw-hcad is an arched arm, M,the free end of which overhangs the path of the coupling-pin, and hollowed or given a socket shape to receive the upper end of the coupling-pin.

On two opposite sides of the upper end of the socket are mounted pulleys a, over which pass the cords p p from the upper end of the coupling-pin laterally over pulleys q q, fixed upon the end of the car, atthe sides thereof, so that by drawing upon either of these cords the coupling-pin will be raised and the cars uncoupled without the necessity of passing in between the ends of said cars. A cord, '1', also leads upward from the top of the couplingpin t0 the top of the car, so that the uncoupling may be performed from the top as well as from each side of the car.

"By providing the draw-heads with the three link-receiving chambers I adapt my couplers to coupling cars of different heights, while at the same time providing guides which hold the link in proper position for coupling.

Having'now fully described my invention, what I claim is- 1. The car-coupler herein described, consisting of the draw-head having a vertical series of link-receivin g chambers, and a suitable passage fbracoupling-pin through said chambers, the wings g y, connected to a common shaft, and arrangcdto swing into said chambers across the path of the coupling-pin, and lever 71, having secured thereto cord 1 and weight k for holding said wings normally at their innermost position, but allowing them to swing outl'OQ ward therefrom when struck by an entering l ling-pin into the socket at the end of said arm, :0 link, substantially as described. substantially as described.
