SPECIFICATION forming part of Letters Patent No. 496,025, dated April 25, 1893.

Application filed December 5, 1892. Serial No. 454,163. (No model.)

A further advan- I00 5 an upward flaring chamber 6 in the rear portage of this construction is that it prevents tion of the drawhead. In this chamber'is lothe hooks from uncoupling and permits them to have a universal movement, so that in rounding curves and passing over any uneveness in the track, no twisting or wrenching takes place. The hooks are so set in the drawhead that their points a will extend back so near the face of the drawhead, that the space between them will be too small to permit the hook to jump out and become accidentally uncoupled. The advantages of this construction are those of simplicity, cheapness, durability, certainty of action, convenience, safety and adaptability to all kinds of rolling stock. It is evident that the righting weight m could be replaced by aspringand that other slight changes that might suggest themselves to a skilled mechanic, might be resorted to without departing from the spirit and scope of my invention. Therefore I do not limit myself to the exact construction shown, but consider myself entitled to all such variations as come within the spirit and scope of my invention.

vHaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car coupling, the herein described hook curved in the form of a segment of a circle, the outer surface of the hook being beveled, the inner surface being obliquely formed to receive a corresponding surface upon the opposite hook whereby the two fit snugly together when in coupled position and thereby enable the hooks to extend backward and overlap the opposite hook when in the said coupled position, in combination with a righting weight secured to the shank of the hook, substantially as described.

2. The combination with a rocking hookshank of a hook secured thereto, an oscillating arm secured to move therewith, an operating arm extending from said oscillating arm, notches or recesses in said operating arm, and

i a plate provided with circular or semi-circular openings through which said operating arm extends, said openings being connected by a slot which receives the notches in the operating arm, substantially as set forth and described.

3. The combination with a rocking hookshank, of a hook secured thereto, an operating arm secured to the shank, a plate provided with openings through which said arm extends, notches in said operating arm and a slot connecting the openings in the plate and MICHAEL I. WELCl-l. Witnesses:
