W. BROOKING. OAR COUPLING Patented June '19, 1894.

UNITED: STATES T PATENT OFFIc WILLIAM BROOKIN'G, OF RIVER, INDIANA.

CARS-COUPLING.

SPECIFICATION forming part of Letters Patent No. 521,699, dated June 19, I894.

Application filed November 2, 18 9 3 To all whom it may concern: i Be it known that I, WILLIAM BROOKING, citizen of the United States, residing at River, in the county of Huntington and State of Indiana, have invented certain new and useful Improvements in Oar-Couplers; 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.

My invention relates to improvements in that class of carcouplers in which the linkpin drops by gravity to confine the link in the draw-head, and also to means for releasing the link-pin from engagement with the link.

My invention is fully illustrated in the accompanying drawings, in which 1 Figure 1 is a vertical sectional View; Fig. 2 a front view; and Fig. 3 a horizontal sectional view.

A indicates the draw-head, having in its rear portion a recess, a, for the reception of a spring, B. 7

0 indicates a spring-actuated sliding block, having the usual flared opening leading to a recess, d, for the reception of one end of the link, D, and provided with a slot, 0, through which the pin, E, falls,in the operation of the device. The block, 0, has an extension, 8:, at its rear end, which supports one end of the spring,B, the other end bearing against the rear wall of the recess, a. v

The draw-head, A, is provided with a hole, (1, extending vertically through it, in which the link-pin, E, slides, and which is adapted to register at the proper time with the hole, 0. The draw-head also has an enlarged recess, F, toward its forward end to provide space for projections, d, d, on therear of the sliding block, 0, the forward part of the recess F, acting as a stop to receive these pro jections and thus limit the forward'play of the sliding block. Extending from the drawa head is an upright, G, the upper end of which is bifurcated horizontally and laterally to provide suitable bearings for levers, H and I, which extend at right angles to each other. Where these levers cross each other they are joined together by means of a block, g, of metal, or other suitable material, which thus forms abearing for the levers, and serves to greatly strengthen them at the point of con- Serial No. 489,886. (No model.)

nection. The levers are held in place by bolts, g, passing through the upright, G. Under this arrangement, the block, 9, bolts 9, lover, I, and the bottom of the groove in which the block, g, rests, operate as a stop to prevent the pin from being drawn entirely the link-pin from engagement with the link. v

The spring B at once pushes the block, 0, forward, until the projections, d, d, strike the end of the recess F, leaving the link-pin resting on the rear, solid portion of the sliding block, 0. When the cars are to be coupled the link, D, presses in the sliding block against the resistance of the spring, until the openings a and a register, when the link-pin will drop automatically and confine the link against withdrawal.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a car-coupler, the combination with the draw-head having a link-pin hole, and of the link and pin, of means for raising the link-pin from engagement with the link, comprising an upright, Gr, having lateral and longitudinal bifurcations in its upper end, levers supported in said bifurcations and extending at right-angles to each other, a block, g, joining said levers and having a bearing in one of the bifurcations, and bolts, 9', for retaining the lovers in position, the combination being and operating substantially as and for the purpose set forth.

2. In a car-coupler, the combination with the draw-head having a link-pin hole, a sliding block working in prescribed limits within comprising an upright having lateral and longitudinal bifurcations in its upper end, levers too supported in said bifurcations and extending at right angles to each other, a block joining said levers and having a bearing in one of the bifurcations, and bolts for retaining the 5 levers in position,substantially as described. 3. In a car-coupler, the combination with the draw-head having a link-pin hole, a sliding block working in prescribed limits within the draw-head and having arecess in its outer [0 end, a spring located in the draw-head and exerting an outward pressure on the block, a link adapted to rest in said recess, and a pin adapted to pass through the draw-head and the said block, of mechanism for raising the.
