CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 376,482, dated January 1'7, 1888.

Application filed July 29, 1887. Serial No. 245.616. (No model.)

To all whom, it may concern:

Be it known that I, ABNER Jonson Mo- GEHEE, a citizen of the United States, residing at Jackson, in the county of Madison and State of Tennessee, have invented new-and useful Improvements in Oar-Couplings, of which the following is a specification.

My invention relates to improvements in car-couplings; and it consists in certain novel features, hereinafter described and claimed.

In the accompanying drawings,which fully illustrate my invention, Figure 1 is a perspective view of the end of a carprovided with my improved coupling. Fig. 2 is a horizontal section showing two draw-heads coupled together. Fig. 3 is a horizontal section of asingle draw-head with the several parts in their uncoupled position. Fig. at is a detail perspective view of the draw-bar, and Fig. 5 is a detail perspective view of the draw-bar look.

Referring to the drawings by letter, A des-- ignates the end of a car, and B the 'draw head, secured to the under side of the same in the usual or any preferred manner. The drawhead B is provided with the forwardly-proje'cting tongues O O at its front ends on oppo site sides of its center, the inner face or side of the tongue 0 being inclined,as shown. The tongueOis horizontally slotted,andis provided with the shoulder D on the inner face of its outer side wall, which is engaged bya similar shoulder on the draw-bar, as will be herein after more full y set forth.

E designates the draw'bar, consisting of an L-shaped body having the coupling-arm F and locking-arm G. The draw-bar is secured in the front end of the slotted tongue 0 by means of a pivot-pin, H, inserted vertically through said tongue and the angle of the drawbar. The coupling-arm F of the draw-bar projects from the tongue 0 of the draw-head and in its outer end has a recess and a vertical pinhole, so that it may be used with the link-andpin coupler, while the locking-arm G extends backward in the longitudinal horizontal slot in the tongue, and is provided with a shoulder, I, on its outer side edge, which engages against the shoulder D of the tongue when the parts are in their coupled position, as clearly shown. The rear end edge of the draw-bar has a beveled portion, J, and a shoulder, K,which shoulder is engaged by a latch, L, pivoted in the rear end of the draw-head,and having its shaft M extended through the side of the same and provided with a crank-handle, N, as shown. This crank-handle N is connected bya chain, 0, to an arm, I mounted on the shaft Q, 'ournaled on the end of the car.

R designates a rod extending to the top of the car, and also connected to the arm 1?.

The operation of niydevice will,itis thought, be readily understood. WVhen the cars are uncoupled, the coupling-arm of the draw-bar projects forward from tl1e.draw-head, as clearly shown in Fig. 3. In this position, if the two draw-heads be brought together, the couplingarm of the draw-bar in each draw-head will enter the opposing draw-head, and, impinging against theinnerinclined face ofthe tongue Oof the draw-head, will be turned inward, the rear sides of the coupling-arms of the drawbars mutually engaging, as clearly shown in Fig. 2. As the draw-bars are swung around by contacting with the opposing draw-head,

the locking-arm will be swung inward, the

beveled rear end of the same passing under the latch L, which falls into engagement with the shoulder K, and the shoulderIof the drawbar engaging the shoulder D of the draw-head.

The coupling will thus be completed and the draw-bars firmly held against uncoupling. To uncouple the cars it is necessary only to turn the shaft M, thus raising the latch L out of engagement with the shoulder K, when the tension on the draw-barswill turn them around,

so that the coupling-arms may slip past each other.

It will be observed that the cars are automatically coupled by my device, and can be uncoupled from the top or side of the car with draw-head in position to engage the notch K, and havingits shaft extended through the side of the draw-head and provided with means for rotating the same, substantially as specified.

' In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

draw-head, in position to engage said notch, and having its shaft extended through thei side of the same and provided with means for S rotating it, substantially as set forth.

2. The combination, with the draw head having the tongues G O, the tongue 0 being provided with the vertical shoulder D on its I inner side, of the draw -bar pivoted in the tongue 0, and having a vertical shoulder, I, engaging against the shoulder D, the rear edge I of the draw-bar being beveled and provided with the notch K, and the latch L, hungin the I
