CAR-COUPLING.

'dPECIFICATION forming part of Letters Patent No. 331,218, dated November 24, 1885.

Application filed July 31, 1885.

To all whom it may concern.-

Be it known that I, GEORGE CALVERT THOMPSON, a citizen of the United States, residing at Darien, in the county of McIntosh and State of Georgia, have invented a new and useful Improvement in Oar-Couplings, of which the following is a description.

This invention is an improvement in carcouplings; and it consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure l is a perspective View of one end of a car provided with my improvement. Fig. 2 is a longitudinal section drawn through the draw-bar. Fig. 3is a cross-sectionof ,Ithefdraw-head, and Fig. 4 is akdetail perspective view of the coupling- The draw-head A may be attached to the car in the usual manner. It is formed with a flaring mouth, A, the mortise A and the slot A theilatter'being'cut through the top wall, as shown. The under side of the forward end of the top wall is formed with the curvedfportion a and :the stop portion a, inclining forward and downwardly from thesaid curved portion.

In the upper faceof the lower side of the draw-head I form a socket or depression, a, in which rests the point of the coupling-hook B. This"'couplinghook B is pivoted on a pin, 0, below the curve a and stop a, and concentrically with the arc in which said curve a is described. The upper forward end of the hook is formed with a curve, I), anda straight stop portion, 1), carried forward from the said curved part 6. These parts b and b can be formed with or fit closely against the parts a aof the draw-head, asimost clearly shown in Fig. 2. The front end, I)", of the coupling-hook is beveled or inclined rearwardly from its upper to its under side, andioperates to guide an approaching link downward toward the point of said hook, so it may readily pass thereunderlinto'engagement,withQthe securing-shoulder b. The point of the hook, itwill be seen,

is rounded to fitithefsocket a and to permit the easy passage of the link under it in the Serial No. 173,198. (No model.)

operation of the device. Immediately in rear of this shoulder b the under side of the hook or its shank is formed with a recess, b, and at its rear end such hook has a depending portion, b terminating in the straight beveled end G of shank, which bevel receives the weight of the hook, relieving the point thereof of all strain.

I11 operation,the recessjf allows free play of the link while the cars are in motion, and enables it to be raised or lowered to couple with a higher or lower draw-head, and the projection If, by bearing on the rear crossbar of the,,link,when such link is pushed entirely in, holdsjsuch link in horizontal posltion to couple with draw'heads of equal or nearly equal height-that is, slightly higher or lower, for when the link strikes the flared mouth A above or below the mortise A the beveled edge will guide the coupling-hook down or up to the mortise and effect an entrance. A spring, D, is secured at its forward end to the draw-head, and, bearing against the rear end of the coupling-hook, operates to hold such hook in the position shown in Fig. 2. On the end of the car, above and on opposite sides of the line of the draw-head, I secure guides E E, preferably anti-friction rollers, as shown. A chain or cord, F, connects with the coupling-hook at f, and extends thence upward between the guides E, where it connects with connections or branch cords F and F F The connection F extends upward, and is held by a keeper, f, in positionlto be reached from theEtop of the car, and the connectionsiF extend laterally over guides f to the side of the car. By pulling on these cords the rear end of the coupling-hook may be elevated and, thejlinklreleasedlbyfaf person on .;either sidebr the top of the car.

My invention, it will beseen, is simple, and provides a construction which will not easily get out of order.

By means of the'several guides'providedlfor the hook-operating devices such parts may be used with but slight friction, and consequently 5 with ease and facility.

Having thus described my invention, what I claim as new is 1. Acar-coupling hook pivotally supported of its top Wall curved at a and extended forat its forward end, and beveled or inclined Ward in a straight line or stop, -a,',and the rearwardly at such end from its upper to its coupling-hook pivoted below the said curved lower side, and having a securing shoulder, and stop portions'of the stop-wall, and having 15 5 12 a recess, 1), in its under side in rear of such its upper forward end curved and flattened at shoulder, and a depending projection, b, at I) Z) correspondingly to saidcurved and stop its rear end. substantially as and for the .purportions a and a, substantially as set forth.

poses specified. GEORGE CALVERT THOMPSON.
