UNCOUPLING-LEVER FOR CAR-COUPLINGS.

Specification of Letters Patent.

llatented May 2, 119i! Original application filed April 24, 1912. Serial No. 692,837. Renewed November 7, 1915, Serial No. 60,419.

Divided and this application filed December 22, 1915. Serial No. 68,211.

tion is to provide a device of novel construction in which a rigid link is utilized for lifting the. locking pin of the coupler, this link being directly connected with the vertically lifting locking pin of the coupler and with the operatillgf member of the uncoupling device by connections which allow the coupler perfect freedom in its normal intended movements, both lateral and longitud1nal,

and which furthermore permits an easy, free, and unimpeded manipiilation of the device during the operation of raising the locking pin.

A further object of my invention is to do away with clevises, bolts, pins, and other parts of like character which are apt to be injured or which may be lost when an uncoupling device comprising such parts is detached from the coupling for the purpose, for example, of repairing the latter.

A further object is to provide a device of the general character herein shown which will operate to automati tally raise the locking pin upon an abnormal forward movement of the coupler due to the? failure of the coupler or some of its connections.

This application is filed as a division of my application filed April 24, 1912, Serial No. (392,337.

In the drawings: Figure 1 is an end elevation of a car. broken away, with my uncoupling lever in position thereon. Fig. 2 is atop plan view of Fig. 1. Fig. 3 is an end elevation of Fig. 1. Fig. 4c is a front elevation of the. rigid link. Fig. 5 is a side elevation of the. rigid link. Fig. (i is a detail view showing. in dotted lines, positions which the link will assume when the cou pler moves laterally. Fig. 7 is a detail view showing. in dotted lines, positions which the link will assume when the. coupler moves longitiulinally under bull' and draft strains.

The reference character '1 designates a car, 2 a coupler, which may be of any improved M. C. B. construction which is re siliently mounted on a car.

A center bracket 3 is mounted substantially at the center of the end of the car and, as shown in the drawing, is secured to the deadwood and is provided with an enlarged opening 5 constituting a bearing for the inner end of the operating rod 6. bracket7 is secured to the end of the car near one side thereof and is provided with an opening which constitutes a bearing for the outer end portion of the operating rod 6.

The operating rod (3 is provided with a depending handle 8 at its outer end which is adapted to lie normally close to the end structure of the car; the inner end ofthe operating rod terminates in a crank or lever '9, which extends forwardly from the end of the connection between the locking pin 11 ofthe coupler and the operating rod 6 is provided at its lower end with an open hook 13, the end portion 14 of which is deflected from the plane of the link and the rest of the hook, the upper portion of the link extending and vertically slidable through the eye 10 of the crankt) of the operating rod, and pro vided preferably with a substantially ball shaped end 14, which, with the eye 10 constitutes, in a. mcasurepa ball and socket joint between the rigid link 12 and the crank of the operating rod, although the ball H is not confined to its socket against upward move ment relative thereto, but is free to permit the rigid link to adapt itself to all normal service n'lovements of the coupler without imposing strain upon any of the parts.

The deflection of the portion 14: of the open hook 13 from the plane of the hook and the rest of the link is relative, and the open space of the hook may be more or less as may be found necessary in service conditions, the object being to provide a more or less (in ell'ect) spiral portion in the hook which will prevent the hook from becoming disengaged from the lock pin by service movements. In other words the rigid link must be given an axial movement to disengage its hook from the lock pin.

\Yhile I have shown my invention in a typical embodiment it will be understood that modifications might be made without departure from the principles of the invention as defined by the claims herein.

\Vhat I claim is:

1. In a release rigging for a car coupler having a lock pin, said rigging including anoperating rod having a c ank', a rigid link provided with a spiral hook at its lower end for connecting said link with the lock pin of the coupler, and a flexible connection between the upper end of the said link and the said crank, whereby the link may move vertically relatively to said crank and rotate about'its longitudinal axis'to permit the engagement and disengagement of said link with said look pin;

The combination with a railway car and a coupler'resiliently supported on the .car and provided with a lock pin'adapted to be raised to its unlocking position and formed with an eye; of a release rigging comprising a rod revoliibly supported on the car, irovided, with a crank, and a rigid member extending from said crank to the lock pin, the upper end of which is connected with the crank slidably, in the direclion of its length, and also flexibly to perinit angular movements of said member botlrforw'ard and back and sidewise, the lower end being provided with an open substantially spirally shaped hook adapted to engage the eye of the lock pin.

3. In combination, a car, a coupler resiliently mounted on the car and having a lock pin which is raised to unlock the same and a .release rigging comprising a link having a substantially spiral hook on one end loosely engaging said lock pin. and an operating rod having a crank provided with means lornied with an aperture through which its extremitydeflected from the plane of the rest of the hook.
