CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 458,237, dated August 25, 1891.

Application tiled Uetober 25, 1890. Serial No. 369,312. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, DAVID T. NICHOLS, a citizen of the United States, residing at Uvilla, in the county of Jefferson and State of West Virginia, have invented certain new and useful Improvements in Car-Couplings; and I do declare the followingrto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in car-couplings; and it consistsin the novel construction and arrangement of parts, as will be hereinafter described, `and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a side view of myimproved coupler. Fig. 2 is a longitudinal section. Fig. 3 is alongitudinal section of one of the couplers ready for engagement.

Referring to the drawings, the letter A indicates the bumpers of a car, having secured to them by means of screw-bolts B the drawheads C. The bumpers are provided with pins c on each side of the draw-heads and spiral springs d surround these pins and having their rear ends so arranged that they The front endsabut against said bumpers. of these springs are connected to a slide c, which passes through an aperture at each side of the draw-heads, so as to allow the slide ample play back and forth in the draw-heads. The slide is provided with a flange f, against which a pivoted latch F impinges at all times either in coupling or uncoupling the link G.

'The link G is also held in position by means of the flange f of the slide e.

The upper surfaces of vthe draw-heads are provided with openings g, through which passes an arm h, said arm having its inner end connected to the latch F, its outer end being connected to a lever H, which is pivoted in a bifnrcated bearing I, connected to the tops of the draw-heads, said lever being designed to operate the latch F to uncouple the cars, which is done bythe pressure of the foot of the brakeman ou the inner end of the lever. The link G always retains itsl position, as shown in Fig. 2 of the drawings. Consequently there is no necessity for going between the cars to couple them, as the same is done automatically when the cars come together; I attach importance to this construction of coupler.

Instead of using the lever on the bumpers, I may, if I so'desire it, operate the lever from the tops of the oars by any well-known means.

Having now fully described my invention,

myself to the precise construction of parts as shown in my drawings and heretofore particularly described, but reserve to myself the right to vary any of the said parts or substitute others therefor for the better carrying out of my invention Without departing from the essential principle thereof.

What I claim, and desire to secure by Let ters Patent of the United States, is-

The combination, with the bumpers having pins c, with springs d, of the slide e, provided with a Hange f, said slide connected to the pins and passing through openings in the draw-head, and a latch F, operated by a leverl to nncouple the cars, substantially as specified.

Intestimony WhereofIaiiix mysignature in presence of two witnesses.
