SPECIFICATION forming part of Letters Patent No. 567,866, dated September 15, 1896.

Application filed March 2Q, 1896A. Serial No. 584,155. (No model.)

The end of the 5o From itsinnerendasomewhatnarroweropencoupling-link, as it enters the draw-head, roo

' pushes the pin-supporting head backward slightly and upward, its projections 12 riding up upon the inclined shoulders 10 and its rearward end sliding horizontally upon the partition 4a. The pin then drops by gravity between the two parts of the bifurcated end and passes through the link and through the opening 8 in the lower wall of the link-cham.- ber, its passage being arrested at the proper point by a lug 17 on the pin, which moves in a channel 18 until it reaches a shoulder 19, which arrests it. It will be seen that I employ any ordinary link, and tha-t the automatic coupling action is rendered practi cally certain by supporting the rearward end of the head 13 upon the horizontal partition 4a, in contradistinction to throwing the entire support upon the inclined shoulders lO, which would be apt to cause the head to bind 0r stick should the parts become worn. By

the compound movement, however, secured by giving the rearward end of the head `a rearward horizontal movement and the forward end a rearward and upward movement, I not only prevent such binding7 but I practically avoid wearing away of the parts in contact and greatly increase the lease with which the head is moved. The head 13 also supports the link, so that it may be caused to enter an opposite draw-head.

In a car-coupling a draw-head having a vertical pin-opening provided with a channel terminating in a shoulder, a pin having a lug to move in said channel and rest on said shoulder when the link is engaged, and an elongated pin -supporting head, having its forward, bifurcated end heavier than the rear end and provided with lateral ears to lie in recesses in the side walls of a chamber in the draw-head, and to move upon rearwardly and upwardly inclined shoulders, while the rearward end of the head lies and is movable upon a horizontal support, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY SCIIAEFFER.
