CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 292,339, dated January Application filed November 3, 1883. (X model.)

To all whom it nwy concern.-

Be it known that I, CASSIUS MOARTHUR, of South Shenango, Crawford county, Pennsylvania, have invented anew and Improved Car- Ooupl ing, of which the following is a full, clear, and exact description.

The object of this invention isto provide a car-coupling which shall be perfectly automatic and reliable in its action, and simple and durable of construction, and easy'to manage in 1 coupling and uncoupling; and to this end the invention consists, principally, of a doublehooked connecting-link having beveled ends, and adapted to act in conjunction with bail or clevis like connections hinged to the drawheads of the cars.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of my new and improved automatic car-coupler, the parts being shown in the position they occupy in the act of and just before coupling. Fig. 2 is a sectional plan View of the same, and Fig. 3 is a front'elevation of one of the couplers."

A A represent the draw-heads. B represents the connecting-link, and O 0 represent the bail or clevis like connections hinged to the'drawheads A in horizontal position upon cross-rods D D. 1

The draw-heads A are attached to the platform E of the cars by the irons F and draw rods G, passing through the rear ends of the draw-heads and attached centrally to rods D, and on these rods Gare placedthe buffer-springs H,which protect the cars from injurious shock when backed together for coupling.

The connecting-link B is formed with the hooks a a,with which the bails C G engage when the ears are coupled, and it is also formed with the inclined portions b b,which serve to elevate the outer-ends of the bails O O as the connecting-link enters the draw-heads, so that the bails O G will drop over the hooks a a and effect the coupling. To prevent the connecting-link B from entering the draw-heads too far when the cars are run together for coupling, I form the draw-heads with the inclined portions 01 in the throats thereof, which act as stops to the en-' trance of the inclined ends of the connectinglinks B, as will be understood from Fig. 1, and 5 the extreme ends 0 e'of the connecting-link are made flat and reach under the inclined portion d, as shown in Fig. 1, for holding the link in horizontal or nearly horizontal position. The bailsG are held on ahigher level than the floors c of the draw-heads, so that the ends of the connecting-link B may pass under them in coupling by the blocks f f,formed upon'or secured to the outside of the draw-heads.

I J represent the nncouplingchains. The former is attached directly to the bails O, the latter to the chain I, and passes thence either to the'top and down one side of the car, (enabling the bail O to be raised from the top of the car or from the ground at the side of the car,) or over pulley K, thence along platform E and through eye L, secured upon and at the edge of the platform, where the chain is pro vided with the ring 9, for holding the chain in place in the eye, and for convenience in drawing the chain for lifting the bail O for uncoupling.

If it is desired to hold the bail C in elevated position, the ring 9 may be caught over the peg g, fitted in the outer edge of the platform E, as shown in Fig. 3.

In operation, for coupling the cars, the connecting-link Bwill be placed in one of the draw-heads of thecars to be coupled and forced back as far as it will go, which will cause bail G to ride up the inclined portion 12 and drop over hook a, and also cause end 6 of the connecting-link to pass fairly under the stop portion d in the draw-head, which. will cause the connecting-link to be held in properhorizontal position. The cars are now simply to be backed together,which will cause the protruding end of the connecting-link B to-enter the opposing draw-head under its bail O, causing the bail to ride up the other inclined portion b and drop over the other hook at, thus completing the coupling of the cars.

To uncouple the cars it is only necessary to raise one or the other ofthe bails C out of engagement with its hook (of the connecting-link B, which maybe done from the top or side of the car by simply lifting or drawing upon the chain J. In this manner it will be seen that the coupler is entirely automatic in its action, and that there is no necessity of going between the cars in coupling or uncoupling. lesides, it will. be seen that the coupler is very simple, effective, cheap, easily operated, and not liable to get out of order.

In case both cars to be coupled are not provided with my new automatic coupler the old link-and-pin coupling may be used and the cars coupled by passing the pin through the openings h h, made in the upper and lower walls of the draw-heads, as shown in Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters 1atent 1. The connecting-link B,formed with hooks to a and inclined portions 1) I), in combination with the draw-heads A A, provided with the bails C C, substantially as and for the purposes set forth.

f, and the bail O, substantially as and for the purpose set forth.

4. The combination of the connecting-link 13, having the oppositely-projecting hooks a a, the inclines b b, and the fiat ends e 6, with the draw-heads A, having the inclined stops (1, and the bails C, pivoted to said draw-heads, substantial] as and for the purpose set forth.

CASSIUS MCARTHUR.
