\VALTER A. SALISBURY, OF LOSANTVILLE, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 471,195, dated March 22, 1892.

Application filed November 30, 1891. Serial No. 413,473. (No model.)

T0 at whom it may concern.-

Be it known that I, WALTER A. SALISBURY, a citizen of the United States, residing at Losantville, in the county of Randolph and State of Indiana, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.

My invention relates to an improvementin car-couplings for freight-cars.

The object of my improvement is to provide means for handling the coupling-pin without going between the cars.

The accompanying drawings illustrate my invention.

Figure 1 represents an end elevation of a freight-oar having my coupling. Fig. 2 represents a side elevation of the same. Fig. 3 represents a longitudinal section of the coupler.

In the drawings, A indicates the draw-bar, which is of the usual well-known construction, except that on its upper side it is provided with a vertical casing B, which incloses and forms a guide for the coupling-pin (J.

The link D is of the-usual form.

Pivoted to the end of the car, so as to swing in a vertical plane thereon, are a pair of levers E E, having at their inner ends each a slotted eye G. The opposed inner ends of levers E E are connected by alink H, to which the coupling-pin is attached by means of a short chain I, the arrangement being such that when the outer end of either of the levers E is depressed the pin is raised and suspended in the casing B. The pin may also be raised by means of a chain or cord I, attached to the top of the car and to link H. For the purpose of holding the link suspended I provide for each of the levers E a vertical guide-bar L, which is supported at each end at a short distance from the surface of the end of the car, so as'to form a slotted Way M, in which the outer end of the lever moves. Pivoted to bar L, so as to swing in a plane at right angles to the plane in which the lever E moves, is alatch N, having its inner end arranged to extend across the slot M in such a manner that the latch will open downward easily, so as to permit the passage of the lever E, but

which forms a stop to the upward movement of the lever. The outer end of latch N is of such weight that its inner end is held nor- L L a shaft 0, projecting beyond the bars L at each end and terminatingin a pair of handles P P.

Immediately beneath the outer ends of each of the latches N, I secure to the shaft 0 a pair of short arms R R, the arrangement being such that when the shaft is turned in the direction indicated by the arrow, Fig. 2, the arms R R engage and raise the outer ends of the latches, thus depressing their inner ends and leaving the slotted ways M clear for the movement of the levers E.

In operation the coupling-pin is raised by depressing the outer end of either or both of the levers E, and, the levers passing in the downward movement the latch or latches N,

and being prevented thereby from returning,

the pin is held suspended, so as to permit the introduction of the coupling-link into the throat of the draw-bar. By turning shaft 0 in the direction indicated by the arrow, Fig. 2, the outer ends of the latches are raised, the outer ends of the levers are released, and the coupling-pin falls through the link.

By the use of this device all danger of the brakeman being crushed between the ends of the cars is avoided.

I claim as my invention- 1. In a car-coupling, the combination of the draw-bar, the pin, the casing secured to the upper side of the draw-bar and forming avertical guide for the pin, the lever pivoted to the end of the car and having its inner end connected to the pin, the slotted way arranged to form a guide for the free end of said lever, and the latch pivoted to the side of said slotted way and arranged to extend across it so as to form a stop for the lever, whereby the pin is raised and held in a suspended position, substantially as set forth. I

2. In a car-coupling, the combination-of the draw-bar, the pin, the casing secured to the upper side of the draw-bar and forminga vertical guide for the pin, the pair of levers pivoted to the end of the car and having each a slotted eye on its inner end, the link connecting the opposed ends of said levers, the chain connecting said link with the coupling-pin, the pair of slotted ways arranged to form guides, respectively, for the free ends of said levers, the pair of latches pivoted to the sides of said slotted Ways and arranged to form stops therein for the free ends of the levers, and the shaft extending from one of said Ways to the other and having a pair of arms arranged to engage said latches, all arranged to co-operate substantially as and for the IO purpose set forth.
