UNITED STATES PATENT OFFICE JOSEPH F. WRIGHT, OF MONTICELLO, ARKANSAS.

IMPROVEMENT lN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 217,501, dated July 15, 1879; application filed December 10, 1878.

To all whom iii-may concern.-

Be it known that I, JOSEPH F. WRIGHT, of Monticello, in the county of Drew and State of Arkansas, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconr panying drawings, and to letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a car-coupling, as will be hereinafter more fully set forth. l in the annexed drawings, Figure 1 is a plan Fig. 2 is a similar view with top re View. moved. Fig. 3 is a bottom View. Fig.4. is a longitudinal vertical section; and Figs. 5, 6,

and 7 are detail views of various parts of my 5 lower end thereof connected with the lever J.

invention. A

A represents a draw-head of any suitable? construction. In each side of the draw-head is pivoted a jaw or clamp, B, which is forced inward by means of a spring, 0.

held in place by the spring-jaws B B on either side, said jaws at the same time, however, yieldih g sufficient to allow the link to have the required amount of play in either direction.

Within thedraw-head is a forked slide, E, 5 g

and coupling-bar F, of the slide-bar ll, having pressed forward by means of a spiral spring, a, behind it, said slide yielding to the pressure of the link when being inserted in the draw-head, and when the coupling-pin is raised F represents the coupling pin or bar, provided on one side with a hook, I), by means of which it is suspended from the center of a double crank, G. This crank extends across the draw-head, so that, by slightly turning the same backward on either side, the cars can 7 be uncoupled without getting on the platform when the cars are not in motion, and the cars can be left uncoupled, if desired.

-When the link enters the draw-head it strikes the coupling pin or bar F and carries it back until it passes the end of the bar, when it drops through the link to its proper place.

The upper end of the coupling-bar F projects through a slot in a platform, H, on top, for guiding the same properly in its movement.

In the bottom of the draw-head is aflanged bar, I, capable of sliding transversely across the same, and against which the lower end of the coupling-bar rests. The sliding bar I is moved backward and forward by means of a lever, J, 011 the under side of the draw-head.

When the bar I is moved so that a slot, 'i, therein comes opposite the end of the coupling-bar, said coupling-bar passes through the slot and the cars are instantly uncoupled.

The lever J is intended to be operated by a lever passing up through the platform, and the A spring, K, may also be used in connection with the lever J to hold the slide-bar Iin position for retaining the coupling-bar in place;

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

1. The combination of the coupling-bar F 1 with hook I), the double crank G, and guide H, substantially as and for the purposes herein set forth.

2, The GOHlblllEttlOIlJWllill the draw-head A slot 2', the lever J, and with or without the spring K, substantially as and for the purposes herein set forth.

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

JOSEPH F. WRIGHT.
