C.AR-COU-PLING.

SPECIFIC TION forming part of Letters Patent No. 293,579, dated February 12, 1884.

Application filed June 15, 1883. (No model.)

To all whom it may concern.-

Be it known that l, THOMAS COKE J oNEs,'

of California, have invented a new and useful Improvement in Oar-Couplings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all' the figures.

Figure 1 is a plan view of my improvement, one of the draw-heads being shown in section. Fig. 2 is a sectional side elevation of one part of the same, taken through the line a: x, Fig.1. Fig. 3 is a front elevation of one part of the same. Fig. 4 is a sectional end elevation of a part of the same. Fig. 5 is a side elevation of the foot-lever and its connections. Fig. 6 is a side elevation of the catch-bar and keeper, the lever being shown in section.

The object of this invention is to facilitate thecoupling and uncoupling of cars, and pro mote convenience and security in the use of such couplings.

The invention consists in a car-coupling constructed with a draw-head having a U- shaped draw-bar connected with the drawrod, with which is also connected a couplinghook held down by a spring and a bow and yoke. WVith the coupling-hook is connected a lifting-bar, a. lever provided with a keeper ver, so that the brakeman can uncouple the cars from the top of a car, as will be hereinafter fully described.

A represents the draw-beams attached to the car-frame, and whichare connected at theirforward ends by cross-bars B to form a seat for the draw-head O. The draw-head Gis cast upon the ends of a U-shaped'draw-bar, D, through the bend of which passes the drawrod E. The draw-rodE is connected with the pin. through the interior of the draw-head (J, and

couple the cars.

its forward end, which enters a recessin the rearend-of the coupling-hook J, and is secured Y can be detached by taking out the bolt K, so

that the car can be coupled by an ordinary link and pin, the draw-head having a vertical hole formedthrough it to receive the said The coupling-hook J extends forward its forward end is inclined or beveled, so that it will be raised by the entering end of the coupling-link L. The coupling-hook J is held in gear with the link L by its own weight, and by the pressure of the arched spring M, the rear end of which is bent around or is otherwise conneeted with the rear end of the said coupling-hook J. The forward end of the spring M rests upon the upper side of the forward part of the coupling-hook J.

Around the spring M and the coupling-hook J is passed a bow, N, the bend of which rests upon the middle part of the said spring M, andjits ends pass through the yoke O and have nuts Pscrewed upon them. The ends of the yoke 0 project so as to rest against the lower side of the draw-bar D, so that the tension of the spring M can be regulated to hold the coupling-hook J down with any desired pressureby adjusting the nut P.

Q is a bar, the middle part of which is bent into U shape, and its end parts are bent outloosely, Without interfering with the movements of the said spring and hook. The arms of the bar Q are held' from spreading, and thus coming off the coupling-hook J, by abolt, R, passing through the said arms. The upper or bent part of the bar Q is pivoted by a bolt, S, or other suitable means-to a lever, T, one end of which is pivoted to a bracket, U, or other support attached to the end of the car V. With this construction, by operating the lever T, the coupling-hook J can be raised to un- The lever T is kept in place bya keeper, W, attached to the end of the car, and is supported,while holding the couplinghook raised, by a catch-bar, X, also attached VVith this construction the coupling-hook J to the said end of the car. The free end of the lever T projects nearly to the side of the car, as shown in Figs. 1 and 3, so that the said lever can beoperated from the side of the track to uncouple the ears, and to lower the coupling-hook J into a coupling position.

To the lever T, at a little distance from its free end, is hinged the lower end of a bar, Y, which passes up through akeeper, Z, attached to the upper part of the end of the car, and has ahandle, a, formed upon or attached to its upper end for convenience in operating it. With this construction the cars can be uncoupled from the top of a car by raising the bar Y, and pushing its upper end outward to cause the lever 'I to engage with the catchbar X. The eouplinghook J can be lowered.

into a coupling position by drawing the upper" the brake or otherwise.

I do not abandon or dedicate to the p ublic any patentable feature set forth herein, and not hereinafter claimed, but reserve the right to claim the same,either in the reisssue of any patent that may be granted upon this appli cation, or in other applications for Letters Patent that I may make.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A car-coupling constructed substantially as herein shown and described, and consisting of the draw-head A, the U-shaped draw-bar D, the spring-pressed coupling -hook .I, the bow and yoke N O, and amechanism for rais ing the coupling-hook, as set forth.

2. In a car-coupling, the combination, with the draw-hcad A, the U-shaped draw-bar I), the spring coupling-hook J, the bow N, and yoke O, of the lifting-bar Q, thelever T, the catch-bar X, and the bar Y, substantially as shown and described.

3. In a car-coupling, the combination, with the draw-head A and the U shaped draw-bar l), of the coupling-hook J provided with a recess at its rear end, spring M, bow N, yoke O, draw-rod E, cross-bars F, slides G, and spring H, substantially as shown and described.

4. In a carcoupling, the combinatiomwith the draw-head A, the Ushapcd draw-bar D, the coupling-hook J the bow J, and yoke O, of the lifting-lever Q, the lever T, the catch-bar X, keeper XV, slotted bar Y, and foot-lever 11, substantially as shown and described.
