LOCOMGTIVE CAR-COUPLING.

Specification of Letters 'Patent. Patgnted Mi 23 1915.

Application filed. March 30, 1914. Serial No. 828,381.

To all whom it may concern Be it known that I, MAsoN B. GIBERSON, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Locomotive CarCouplers, of which the following is a specification, reference being had therein'to the accompanying drawings.

The invention relates to car couplers and more particularly to couplers adapted for the attachmenet of the cars to the locomo tive. With the standard construction now in use locomotive couplers are provided with relatively short shanks which engage a pocketed fitting secured to theframe of the locomotive. The pocket in the fitting is so fashioned as to permit a lateral angular movement of the coupler and shank and the latter is retained from disengagement by a pivot pin extending vertically through the fi ting and shank. The end of the shank is adapted to abut against the end of the pocket to transmit the thrust when buffing, but the draft when the locomotive is moving forward is transmitted through the pin. One defect in constructions of this kind is the tendency for the coupler shank, pocket member and pin to wear so as to permit the hooked end of the coupler to droop or sag. This throws all of the pullin stress upon the upper portion of the coupling hook, which weakens the. structure and is otherwise objectionable.

It is the object of the present invention to avoid such defects, which is accomplished by the construction as hereinafter set forth.

In the drawings :'Figure 1 is a sectional side elevation of the coupler and the pocketed fitting for receiving the same;

Fig. 2 is a plan view; Fig. 3 is a plan view showing the coupler detached, in position for engagement; and Fig. i is a horizontal section through theattached coupler.

A is the coupler head, B is the pocket fitting which has the pocket or recess C for receiving the shank D of the coupler, and E is the pivot pin passing through the walls of the recess and through the shank D, provided with sufficient clearance from the latter to permit. the end of the'shank to bear against the bottom of the pocket in buffing.

To hold the coupler from drooping and 1 also to assist in transmitting the draft stress I have provided an interlocking engagement between the upper portion of the coupler and the pocket fitting. As shown, the coupler head is provided with an upward extension G having a rearwardly eX- tending lug H terminating in a downward hook I of segmental form, the segment being substantially concentric with the axis of the pin E. The fitting B is also provided with a forwardly-projecting member J having an upwardlyextending segmental hook K for engaging with the segmental hook I. The hook K is cut away at one side to form an entrance slot L of sufiicient width for the insertion of the hook I when the shank is turnedto its extreme angular position. L is a pm which normally holds the shank from turning to this extreme position and.

therefore prevents accidental disengagement of the hook I from the hook K. The engagement of the hooks I and K will prevent the rear end of the coupler from drooping, and furthermore, the draft instead of horizontal plane, and is as readily attach able and detachable as with constructions heretofore used.

What I claim as my invention is 1. In a car coupler, the combination with the coupler head and shank, of a pocket fitting for receiving said shank providing for lateral angular movement thereof, a a pivot-pin for attaching said shank to said fitting, and interlocking means between said pocket fitting and coupler at the upper outer edge of the former, cooperating with the bearing of said shank in said pocket fitting to hold the coupler from drooping.

2. In a car coupler, the combination with the coupler head and shank, of a pocket fitting for receiving the shank providing for the lateral angular movement thereof, a-

pivot pin for attaching said shank to said fitting,

and-inter-engaging segmental hooks on said coupler and fitting located at the upper outer edge of the latter and in 00- operation With the bearing for the shank Within said fitting, holding said coupler from drooping.

3. In a car coupler, the combination with the coupler head and shank, of a pocket fitting for receiving said shank providing clearance for the lateral angular movement thereof, a pivot pin for connecting said shank to said pocket fitting, and inter-engageeble segmental hooks on said coupler head and pocket fitting arranged concentric to the axis of said pin, one of said hooks being cut away to form an entrance slot when the coupler is in extreme angular position.

4. In a car coupler, the combination With the coupler head and shank, of a pocket fitting for receiving said shank providing clearance for the lateral angular movement thereof, a pin for connecting said shank to said pocket fitting, cooperating lugs of segmental form on said fitting and coupler head, one of said lugs being cut away to form entrance slot when the coupler is in extreme angular position, and detachable means for preventing the disengagement of said lugs.

In testimony whereof I afiix my signature in presence of two Witnesses.
