UNITED STATES PATENT Fries@ RICHARD E. GRAY, OF VILLIAMSPORT, PENNSYLVANIA.

CAR-COUPLING.

SPECIFICATION forming part of LettersPatent No. 289,40*?, dated December 4, 1883.

Application filed December 8, 1882. (No model.)

To all wiz/m it may concern:

To thefront ends of the draw-bars A are Beit known that I, RICHARDE. GRAY, of pivoted the hooks E E, which constitute the Villiamsport, in the county'of Lycoming and State of Pennsylvania, have invented certain new and useful improvements in Car-Coup-V recited at the close of the specification.

In the accompanying drawings, Figure l is a perspective view of my improved coupling;

`and Fig. 2 is a plan or top view of one ofthe l able my present improvements to be understood.

The draw-bars A of the twin-coupling are secured beneath the cars, preferably by means of metal straps B, which permit slight endwise movement of the draw-bars without lateral play. The rear ends of the draw-bars are firmly connected to the usual draft-bars or rear sections, C, of the drawlbars, which are also secured beneath the cars, as usual-for in stance, by suitable metallic straps and boltsso as to have slight endwise play with their bars A. Strong buffer-springs D are fitted to or in said draft-bars C, as usual, so as to ease the jar when the cars come together to be coupled. 'Ihe drawbars A and rear sections, C, thereof are secured centrally 'beneath the cars, so as to place the draft at the `center thereof.

-ready mentioned.

coupling devices proper. The reduced shanks e of said pivoted hooks are fitted in recesses in the draw-bars A, and are adapted to be rigidly locked therein in their coupling position by means of simple coupling-pins F, as fully de scribed in lmy aforesaid patent.

The safety-latch G, also described in myw aforesaid patent, is employed to uphold the coupling-pin until the proper time arrives for locking the coupling-hook. The front ends ofthe coupling-hooks inthis example, it will be seen, are different in construction from those shown in my aforesaid patent, being curved or rounded so as to iit into corresponding recesses H in the opposite draw-bars when the cars are. brought together, whereby the pivoted hooks, in addition to their coupling capacity, also constitute the buffers of the cars. The front ends of said coupling-hooks are also deeper than the draw-bars, to which they are pivoted by their reduced shanks, and extend both above and below the front ends of the said draw-bars. This is for the purpose of y giving a wider range up and down to the coupling devices and to enable cars to be coupled at greater inequalities of height, and for the further purpose' of enabling me to form quite extensive recesses e in thefaces of 'the coupling-hooks for the ordinary coupling -links without unduly weakening the coupling-hooks or interfering with their bufting or coupling actions. Y

J ust back of the curved seats or recesses H of the draw-heads, and on top ofv said drawheads, are cast or fastened transverse ribs or flanges c, which, when the cars are brought together, with the couplinghooks in buffing contact, abut against theend sills, I, of thecars and prevent the draw-heads from being driven back beneath the cars.

It will thus be seen that bythe organization now shown the coupling-hooks constitute the bufng devices, aswell as the coupling devices, in connection with the buffing-ribs nc above described, while the draw-bars are given slight endwisemovement for the purpose of easing the jars by means of the.`buff1ngsprings alrIhe coupling-hooks also, by reason of their curved front ends or faces, are caused to fit snugly into the curved re-V icc g cesses of the draw-heads, and thereby insure the proper action upon the coupling-hook Shanks and upon the safety-latches G to cause the coupling connection. As before stated, the draw-bars A are capable of moving end- Wise in their central guides or fastenings be- 4 neath the car-bodies, while having no lateral or sidewise play.

Having thus described in y iniprovein ents, I claim herein- The combination, in a twin coupling, ofthe draw-bars, the curved end-pivoted hook-couplings thereof, the connections which secure said draw-bars centrally beneath the cars, so as to inove endwise but not laterally, the curyed buffer-seats in the front ends of said draw-bars,
