CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 243,538, dated June 28, 1881.

Application filed May 19, 188i. (Model) To all whom it may concern:

Be it known that I, THOMAS FARRELL, of Dubuque, in the county of Dubuque and Stateof Iowa, have invented a new and valuable Improvement in Oar-Couplers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a top view of my invention. Fig. 2 is a side view, and Fig. 3 is a longitudinal section, of the same.

This invention has relation to improvements in means for coupling cars, and has for its object the production of a device whereby the cars can be readily and automatically coupled.

The invention consists in the construction and novel arrangement of parts, hereinafter described, and especially pointed out in the claims.

In the accompanying drawings, the letter a designates an open-top draw-head having an upwardly-beveled lower lip, b, in which are made two notches, c and d, side by side, the former having shoulders o in front.

Extending back from the lip is a wall, 0, on the sides of which are the channels fand g, which terminate at the lip b,formin g shoulders f and g back of said lip, the notches c and d running into these channels, but having their bottoms above those of the latter, so that the shoulders 19 and g are formed.

Located in the channel f, and rising from the side of the draw-head, is a hearing, h, parallel to the tongue 0, and between said hearing and tongue is pivoted by a bolt, h, the couplinghook 7c. The coupling-hook projects beyond the draw-head, its rear end, k, fitting the groove or notch c, and having shoulders k corresponding in position to the shoulders c. The rear-portion, 7c, of the couplin g-hook is forked at its forward end, forming bearings k between which the front portion, 1, of the coupling-hook is pivoted. A recessed hearing or stop, It, is provided under the broad or forked end of the rear portion, k,'in which the rear end of the front portion, Z, of said hook is received when said hook is extended in working position. The forward end of the front of the couplinghook is provided with the beveled head m, havthe rear shoulders, m being adapted in form to engage the shoulders in rear of the lip of the opposite draw-head, which is designed to beof similarconstruction. Thecoupling-hook being jointed in the manner described, its front or catching portion can he raised and held back to prevent coupling when desired; or it can be set against a bearing, .2, on the rear part, 70, so that when the cars come together it will fall forward into engagement with the opposite draw-head. Provision is also made for using the ordinary pin-and-link coupling by forming in the lip b the ordinary mouth and pin-opening, as indicated in the drawings.

Extending transversely through the drawhead is arranged the operating crank-sh ank n, having the elongated crank n, which is connected to the coupling-hook. This operatingshaft is also provided with exterior handles, a n There is also formed on said shaft, outside the draw-head, a crank-loop, 19, having a.

shoulder or bearing, 19, next the wall of the draw-head. The crankloop p extends forward,

and below it is pivoted to the wall of the drawhead a dog, H, having its upper edge beveled or rounded, and provided with a pin, q, a little forward of its pivot. A link-connection, 1, extends from the crank-loop p to the pin g. This construction is designed to throw the dog H under the bearing 19' of the shaft when the latter is turned backward, thereby holding up the coupling-hook. A guide-bearing, s, is provided on the outside of the draw-head, in front of the lower portion of the dog H, and a slide bar, to, is arranged therein. Said bar is designed, to have sufficient length to project in front of the draw-head, and is provided with a stop-slot, s,and pin 22, to limit its movement. When the draw-heads of opposite cars come together the projecting end of the slide-bar will become engaged, and said bar will he pushed back, its rear end striking the lower portion of the dog H, which will thereby be moved from under the bearin g of the crank-shaft, so

that the hook will be allowed to drop and become engaged with the opposite draw-head.

In some constructions it may be advisable IOG to make the coupling-hook Without a joint. I its coupling-hook, of thetransverse operatingdo not, therefore, desire to be confined to the crank-shaft n, the crank-loop 1), bearing 1), link employment of the jointed coupling-hook. r,dogH, and slide-bar w,substantially as specir 5 Having described this invention, what I fled. 5 claim, and desire to secure by Letters Patent, In testimony that I claim the above I hm'e ishereunto subscribed my name in the presence 1. The jointed coupling-hook having the of two Witnesses.

forked rear portion, k,,the recessed bearing 1 under the forked end thereof, and the front or THOMAS FARRELL 1o catching portion, l, pivoted to the rear portion, Witnesses:
