CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 281,779, dated July 24, 1883.

Application filed May 26, 1883. (F model.)

To all whom, it may concern:

Be it known that I, FRANK MILLER, of Olema, Marin county, and State of California, have invented an Improvement in Gar-Couplings; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful improvement in car-couplings, and particularly in that certain car-coupling heretofore 1o patented by me, May 2, 1882, No. 257,234..

My invention consists in the means hereinafter described for forcing back the guard and swinging the coupling-bar to one side to uncouple the device, and in means for adapting I 5 the coupling for use in connection with the ordinary link and pin.

The object of my invention is to simplify the construction of my former coupling in so far as it relates to the means for uncoupling the device and to adapt it to a more extended use.

Referring to the accompanying drawings, Figure 1 is a perspective view of my car-coupling. The device is here shown as upside down. Fig. 2 is a front elevation. Fig. 3 is a longitudinal section. Fig. 4 is a plan 011 an enlarged scale.

A is a portion of the platform of the car. B isthe coupling-bar, pivoted at its rear end 0 under the platform. The forward or outer end of the bar is provided with a rounded head or hook, 0, having a notch forming a shoulder, c, for engaging with the similar head or hook of the opposing or meeting bar.

0 is aspring under whose influence the coupling-bar is held straight.

D is a guide or stirrup in which the coup ling-bar rests.

D is a supporting bar or guide for the back. E is the guard-bar. This lies parallel with and adjoining the coupling-bar. Its inner or rear end fits through an eye, 0, formed in the head of a bolt, 6, passing through bar B, and secured by a nut, as shown. Its forward or 5 outer end is curved away from the hook of the coupling-bar, but yet extends far enough forward and close enough to said hook to make the opening between them too small for the opposing hook or head of the other coupling- 50 bar to enter into or free itself from engagement with the first hook without first forcing back the guard to increase the opening. In entering it is enabled to do this because it bears against the end of the guard, and thus forces it back; but it cannot be freed except by other means. Between the bearing-eye e and a shoulder formed on the guard-barEisa spring, f, which returns the guard to its place.

The parts thus far described are substantially'silnilar in construction and operation to 6 those shown in my former patent.

My improvement is as follows:

G is an elbow-lever, having a pin or shaft, 9, at its angle, by which it is pivoted under the platform. The pin is journaled in the platform 6 5 and in the cross-guide D. The arms of lever G extend from this pin or shaft at right angles to each other and 011 different horizontal planes, the one lettered h being higher and extending over the guard-bar B, and impinging against 0 a stop, (I, on said guard, and the other, 71., being on a lower plane and adapted to strike the side of the guard. This arm is bent at its center toward the guard in order to bear against it and force it sidewise.

H is the lever by which the lever G is operated. By throwing this lever to one side the elbow-1ever G is moved on its bearing, first causing its arm h to force back the guard D by pressing against the stop (I, and then by means of its bent arm h forcing the guard and coupling-bar B to one side. This double movement has the effect, first, of withdrawing the guard to release the opposite hook, and then of forcing the first hook to one side to complete the disengagement. All the parts of the opposite portion of the coupling are the duplicates of those described, the relative position of each being reversed in order to effect the coupling and uncoupling. This elbow-leo ver G is simple in construction and compact.

The head 0 of the coupling-bar is provided with a slot, b, and a hole, I), in order to adapt the coupling for use upon freightcars in case a car having the ordinary form of coupling 5 should have to be coupled to it. In that case the link could be fitted in the slot 2) and the coupling-pin dropped through hole I). The guard, being in such event useless, could be re-- moved by releasing the bolt e.

Having thus described my invention, that I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupling, the pivoted couplingbar B, having hook-head c, the spring 0, and the sliding guard-bar E, having spring f, in combination with the pivoted elbow-lever G, having arm 7:, bearing against a stop, (I, on said guard, and bent arm h, bearing against the side of said guard, and a means for operating the elbow-lever G, substantially as herein described.

2. In a car-coupling, the pivoted couplingbar B, having hook-head 0, spring 0, and sliding guard-bar E, having spring f and 'stop (Z,

in combination with the pivoted elbow-lever G, having arm 71 and the operating-lever H,

I connected with bent arm 71 substantially as herein described.

the pivoted coupling-bar 13, having a hookhead, 0, in which is a slot, b, a hole, Z), the

and stop d, the eyebolt a, connecting the guardbar with the coupling-bar, and the elbow-1e ,ver G and operating-1ever H, all arranged spring 0, the guard-bar E, having spring f 3. In a car-coupling, the combination of 20 and operating substantially as hereinbefore de
