IMPROVEMENT IN CR-COUPLING'S.

Specification forming part of Letters Patent No. 58,219, dated December 529, 1874; application filed Y June 10, 1874.

To all whom it may concern:

Be it known that I, GEO. RODNEY MOORE, of the city and county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Oar-Couplings, of which the following is a specication:

The object of my invention is to provide facilities for coupling cars with the ordinary link and pins, automatically, at least so far as to save from personal exposure the operator 5 also, to save the link from exposure to injury from the instrumentalities I employ in coupling, by providing for their immediate removal automatically out of the way. My device may be considered in two divisions, as acting in one part for holding and releasing the pin, and in the other for holding the link, both of which are automatically removed out of the way of the link as soon as the cars are put in motion.

Figure l is a top view of the front portion of an ordinary draw-head containing` my device, shown with the upper plate of the drawhead removed. Fig. 2 is a longitudinal vertical section of Fig. 1, with the top plate of the draw-head restored. Fig. 3 is a perspective view. Fig. 4L is a longitudinal vertical section of the coupling, showing the pin when ele- 4 vated and resting on the plate l). Fig. 5 is a horizontal section of the arms E and F, showing the position of the spring G.

A is the draw-head; B, the pin; G, the link, D, a top plate, projecting forward from the arm E, of which it is a part, to sustain the pin for the time needed. E is a swinging arm, loosely jointed to the shaft H, and operated within certain limits by the spring G. F is an arm, rigidly fastened to the shaft H. G is a spring, fastened to F and playing freely upon E at a point outside of its proper fulcruin on H, so that the tendency of .this spring is to keep the inner end of E close up to the inner end of F, thus causing D to come far enough forward to hold up the pin, while F is left far enough back not to interfere with the link. H is a vertical shaft, passing up through both plates of the draw-head and placed sufficiently on one side to be always out of the way of the link. In this case it carries all the parts of my device, although separations might be made and another shaft brought into use. I and II are friction-plates. I is fast to H, and I left free to move upward, but not to turn on H. J is a spring; K, a screw-nut for forcing the spring J and plate I' against the solid plate of the draw-head, and thus increasing the frictional hold of the shaft H to any desired extent, for either bringing the clamps E and F into use, or for holding them both e11- tirely out of the way of the link when the cars are running, by which provision all injury to the link by wear from my coupling device is avoided. m is a guard, and wa stop-lever, by which the operator can never go amiss in placing my device for its work.

The operation of this coupling is as follows: Bearing in mind that there are two draw-heads with. the same device complete, and two pins, but one link, then, first, that the 'main object of E and D, loosely jointed to H, and operated to a limited extent by the spring G, is to hold up the pin until the link from the other draw-head to be coupled shall come against E and press it back, (the spring allowing it to go far enough to release the pin Without moving F at all,) when the pin will drop into the said link, and the act of coupling be thereby completed; and, second, that the main object of F is to clamp the link against the pin, and thereby hold it firmly enough in the one-drawhead to carry it into the other and to release the pin, as above shown, by which, again, the act of coupling is completed; after this, if when the cars start the link presses sufficienti y against F to overcome the friction of H, as adjusted, both arms E and F will be pushed back out of the way until again manually brought forward for another act of coupling.

The parts to be done manually in preparing my device for automatic coupling are, iirst, in one draw-head, turn H, by the crank or lever extending out from it, back against the guide m. That will bring D in place to hold up the pin, in which condition it should receive it. Second, in the other draw-head, turn H back so as to bring F firmly against the link, so clamping it against the pin in right position to enter the draw-head; then running the cars together they will couple, as before explained.

I claim as my inventionl. The arm F, in combination with shaft H, with the shaft H, arm F, spring` J, and nut K, friction-plates I I', and nut K, as and for the as and for the purpose set forth. purpose set forth. 5. The guard-plate m and stop-lever n, in 2. The combination of the erml E and plate combination with the shaft H and arms E D with the arm F and shaft H, as and for the and F, as and for the purpose set forth. purpose set forth.
