CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 275,428, dated April 10, 1883.

Application filed October 24, 1882. (No model.)

To all whom it may concern Be itknown that I, JACOB G. SLA'IER, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification, reference being had to the accompanying drawings.

Figure l is a perspective view. Fig. 2 is a longitudinal vertical sectional view oi' the draw-head, showing the coupling-hook raised. Fig. 3 is a longitudinal vertical sectional view of the draw-head, showing the coupling-hook dropped and the link in position. Fig. 4 is a front view. Fig. 5 is a detail view'of the coupling-hook detached, and Figs. 6, 7, and S are detail views of parts of the coupling.

The same letters refer to the same parts in all the gnres.

This invention relates to automatic or selfacting car-couplings; and it consists in certain improvements in the construction of the same',

which will he hereinafter fully described, and particularly pointed ont in the claims.

In the drawings hereto annexed, A represents the draw-head, having the mouth or recess B, and provided with a "ertical slot, C, at the sides of which lugs D D are cast, on the upper side of the draw-head, to receive a bolt, E, upon which an oval plate or eccentric, F, is mounted, as shown.-

G is the coupling-hook, which issubstantially-of the shape shown in the drawings, and provided at its rear part or heel, G', with a slot, H, by which it is mounted upon a transverse bolt, I, in the draw-head A. The coupling-hook G is provided with an upwardprojecting shank or handle, J, by which it may be conveniently manipulated, or to which an operating cord, rod, or chain may be attached.

K is a plate having in its under side, at its rear end, a recess, L, in which the front end of the oval plate or eccentric F is hinged by a transverse bolt, M. The front end of plate K has a slot, N, in which the shank J of the coupling-hook is hinged by a transverse bolt or pin, O.

The draw-head A is provided at the sides of the mouth or recess B withvertical openings P P, to receive the legs Q Q of a vertically-sliding bail, It. The lower ends of the legs Q are bent inwardly, so as to form arms S, which extend into the mouth or recess B, the bottom of which is providedwith reccesses T to accommodate said arms S. The upper end of bail R has a loop, U,to which an 0perating-chain may be attached.

The operation ot' my invention will be readily-understood from the foregoing description, taken in connection with the drawings hereto annexed.

When the coupling-hook is lifted it at the same time lifts lthe plate K and eccentric F, which latter throws the said plate and hook in a rearward direction to the position shown in Fig. 2, the slot H permitting the coup ling-hook to assume this position, in which it is retained by its own weight. When a link enters the draw-head it strikes the heel of the coupling-hook, whichis thereby thrown forward to the locked position shown in Fig. 3. By means of the hail It the link may be raised and guided into the draw-head of an adjoining car.

I claim as my invention- 1. In a car-coupling, the couplinghook G, having slot H, whereby it is pivoted upon the pin I, shank J, and heel G', the latter adapted to be struck by the link entering the drawhead, as set forth.

2. The combination, with the pivoted coupling-hook G, having slot H, whereby it may have a sliding movement when raised, shank J, and heel G', of the hinged or pivoted eccentric F and the connecting-plate K, as set forth.

3. In a car-coupling, the combination, with the pivoted coupling-hook G, having slot H, heel G', and shank J, of the eccentric F and the connecting-plate K, having recess L to receive and cover said eccentric, and having its front end bifurcated and pivoted to the shank of the coupling-hook, as set forth.

4. The herein-described improved car-coupling, consisting of the draw-head A, having recess B andsiot C, the pivoted coupling- In testimony that I claim the foregoing as hook G, having slot H, shank J, and heel G, my own I have hereto axed my signature in the eccentric F, connecting-plate K, and the presence of two witnesses.

vertically-sliding bail R, having arms S, eX- JACOB G. SLATER. tending into the month of the draw-head and Witnesses: accommodated in recesses T in the same, as E. W. GREENMAN,

set forth. MICHAEL MILLER.
