CAR-COUPLING.

SPECIFICATION forming part of Letters Paten!l No. 323,195, dated July 28, 1885.

Application filed December 10, 1884. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, ROBERT T. MORRISON, J r., of Medina, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Car-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and usev the same.

My invention relates to improvements in carcouplers, having forits object a combined automatic hook-coupler and substantially an ordinary link-coupler.

Vith these objects in view my invention consistsin certain features of construction, and in combination of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view showing two of my improved devices coupled by their respective hooks. Fig. 2 is a plan View of one of my improved drawheads coupled by a link to an ordinary drawhead. Fig. 3 is an end view in elevation of my improved draw-head and hook-coupler. Fig. 4 is a View in perspective of the hook.

A represents the draw-head proper, that is attached to any draw-bar of ordinary construction, A. On the respective sides of the drawhead, and integral therewith, are the bumpers B and B, of unequal length, and adapted to receive the thrust of similar bumpers on au opposing draw-head. These bumpers are separated far enough to admit an ordinary linkfastening draw-head between them, and the part A has a at face, c, andalink pocket and pin, a and c2, so that these draw-heads may be coupled in the usual manner with the ordinary link-coupling devices.

C is the hook-coupler, that extends back into the slot D, and is pivoted on the pin d, the pin crossing the plane of the hook at a right angle, and each standing at an angle of about forty-five degrees from a transverse horizontal line through the draw-heads; consequently opposing hooks stand or move at right angles to each other. rIhe hooks, as shown in Fig. 4, have an inclined under face, c, at the forward end, by means of which,when the opposing hooks are brought together, one or both of the hooks are raised obliquely until the points have passed each other, and then fall by gravity and engage a hook over each other, as shown in Fig. l. In case a linkcoupling draw-head approaches, the hook, by means of the incline aforesaid, mounts, unless otherwise elevated, the draw-head, and remains resting upon it. When the draw-heads are not coupled the bottom wall of the slot D is about in the position shown in Fig. 3, and ready to engage another hook on a linkcoupling draw-head. The face of the hook proper c isslightly curved, as shown, and recedes from the pivotal point as it approaches the shank, and, by .means of such form, two hooks, whenv engaged, have a tendency to draw together rather than to separate. The one side of the face a is cut away at as, to make room for the point of the opposing hook; but there is still left ample surface to form a bumper, so that this part of the device is substantially as an ordinary link-coupler.

The hooks may have a chain, cord, rod, or any suitable device connected at c2, by means of which the hooks may be uncoupled from the side or top of the cars, and by means of such attachment the hook may be in any suitable manner held with its free end suspended in the position shown in Fig. 2.

The face of the hook c is of such length that several inches difference in the height of cars will not interfere with the operation of the hooks that in such cases will engage each other, the one near the point and the other near the shank of the hook.

The bumpers B and B might be of equal length, each extending about half as far as the former; but in such cases it would not be so convenient to couple with links as with the construction shown, where one si de ofthe drawhead is unobstructed.

The pocket a', the slot D, and the pin-holes may all be formed so that little or no fitting is required, and the device can therefore be made at a small initial cost, while the absence of springs and complicated mechanism is greatly in its favor as a durable and practicable carcoupler.

Vhat I claim is-e l. The combination, with a draw-head having an elongated open slot formed therein, preferably at or about an angle of forty-tive degrees from a transverse horizontal line through the draw-head, of a hook pivoted at one end within said slot and extending outward and ICO terminating beyond or outside of the drawhead, substantially as set forth.

2. The Combination, with a draw-head having an elongated open slot formed therein, preferably at or about an angle of forty-five degrees from a transverse horizontal line through the draw-head, and also provided with a buffer-face and link-pocket, of a hook pivoted at one end within said slot, and extending outward and terminating beyond or outside ofthe draw-head, substantially as set forth.
