T at whom it may concern.-

Be it known that I, J AMES E. N ISBET, a citizen of the United States, residing at Jacksonville, in the county of Calhoun and State of Alabama, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

This invention relates to car-couplings; and its object is, first, to provide means for coupling the draw-bars and the air-pipes which run along the train for the purpose of operating the brakes and for uncoupling the cars and to do this coupling automatically by the act of pushing the cars together, and the second object is to provide means for operating the coupling devices to uncouple them.

To this end my invention consists in the construction and combination of parts forming a resents the same two draw-bars coupled. Fig. I

3 shows a top view of the same two draw-bars approaching each other to be coupled. Fig. 4 is a front end view of one of the draw-bars. Fig. 5 is a side view of one of the draw-bar hooks on a larger scale.

7 represents the body of a draw-bar which may be attached to a car in any usual manner.

9 and 10 represent two coupling-hooks, one at'each side of the body 7 and both pivotally hung upon a heavy cross-pin 8. The hook 9 has a long incline 11, upon which the rounded toe 12 of its mate hook 10 of another car slides as the cars come together in the act of coupling. One of these hooks is always 10- cated at the right-hand side of the draw-bar and the other at the left as we stand in the car and face the end. As here shown, the hook 9 is at the right and the hook 10 at the left, and in coming together the hook 9 will engage the hook 10 and the hook 10 will engage the hook 9. On the side of each hook is located a short section of pipe. The pipe 13, located upon the hook 9, is a nipple, and the pipe 14, located upon the hook 10, is a socket to receive the nipple, and yet the socket 14 is also tapered to enter a short sleeve 15, located around the nipple 13, and 16 represents packing material in the sleeve, against which the end of the socket 14 abuts to form an air-tight joint in service.

To the short coupling-pipes are attached flexible pipes 17 17 18 18, one line to communicate with air-brake mechanism and the other with mechanism for uncoupling the cars; but as such mechanism is common and is no part of this invention I have not shown it in the drawings, yet I have shown the direct means by which such mechanism may operate my coupler, as follows: The coupling-hook 9 is provided with a downward-projecting stud 19, which extends far enough from the pivot 8 to serve as a lever-arm, to which a connecting-rod 20 is attached, so that a rearward pull upon rod 20 \vill'pull the forward end of hook 9 downward. This movement is constantly resisted by a spring 21, which has a pushing action between the stud 19 and a post 22, which is fixed to the draw-bar. Thehook 10 is provided with a stud 19, a connectingrod 20, a spring 21, and a fixed post 22; but

as the hook 9 moves downward and the hook 1O upward to uncouple I have connected the two rods 20 and 20 with a reversing-lever 23, which is pivoted at 24 to the body 7 and is provided with a push-rod 25, which may receive motion from the piston of an air-cylinder or other motive power usual for such work. Each of the coupling-pipes 13 14 is provided with a valve which remains normally closed when one pipe is not coupled with another. The valve 26 in pipe 14 is provided with an arm 27, having at its end a crank-pin 28, which extends forward in the line of the cars to engage a brace 29 on the pipe 13 by entering a'hole 30 therein when one hook slides upon another as the cars come together. The brace 29 is pivoted at 31 to a fixture-of the pipe 13, and when two hooks come entirely together and are pushed by their springs 21 21 into engagement the brace 29 swings to the position shown in dotted lines 32, Fig.. 4, and carrying with it the crank-arm 27 28 it opens the valve in pipe 14. The valve 26 is provided with a similar crank 27 28 to be engaged by the oncoming brace 29 and turned to the position shown in dotted lines 36, which opens the valve 26, and communication is established in the line of pipe 17 17 through this coupling. The opposite hooks 9 and 10 are provided with the same style of valves and connections, so that the two lines of pipe are coupled by the act of coupling the drawbars, and it is all done automatically when two cars provided with my invention come together.

lt will be understood that valves may be arranged in the coupling-pipe of each car, so that a brakeman may turn them and open communication with the uncoupling mechanism at any time, and then the engineer may uncouple that car at the desired time by senoling a charge of compressed air along the pipe and drop out that car and leave it at the station desired without stopping the train. The act of uncoupling closes the valves at the couplings by the reverse action of the parts which operate to close them in the act of coupling. The value of a coupling device by means of which both the draw-bars and airpipes of cars may be automatically coupled and be uncoupled at will without stopping the train is evident.

Having thus fully described my invention, what I believe to be new, and desire to secure by Letters Patent, is the following:

1. In car-couplings, a draw-bar body; a coupling-hook pivoted at each side of the said body, one hook facing upward and the other downward; a stud projecting downward from each hook near its pivot; springs between those studs and fixtures to the aforesaid body actuating the hooks toward engagement; a revers1ng-lever pivoted to a fixture of the car; connecting-rods between the said studs 2. In car-couplings, a draw-bar body; a coupling-hook pivoted at each side of the body, one hook facing upward and the other downward; an air-pipe attached vertically to the side of each coupling-hook, the end of one of the said pipes being tapered to enter and the other to receive a corresponding pipe; the pipes on two corresponding hooks being located to engage each other when the hooks engage.

3. In car-couplings, draw-bars; couplinghooks pivoted thereon; pipes adapted to be coupled together. and attached to the hooks; Valves in the pipes; a crank-arm for each valve, and a brace pivoted to the hook to engage the crank-pin of the corresponding valve.

4. In car-couplings, coupling-hooks hung to engage each other; pipes attached to the hooks and adapted to be coupled by the act of coupling the hooks; valves for the pipes, each valve having a crank-arm with the crankpin in line of the cars travel, and a brace on the hook opposite to each crank, the brace being adapted to receive and guide the crankpm.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
