NITED STATES JAMES C. MITCHELL, OF LANCASTER, N. H., ASSIGNOR TO HIMSELF, JAMES A. SMITH, AND ALDEN R. TINKHAM, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 259,647, dated June 13, 1882.

Application filed May 15, 1882.

To all whom it may concern:

Be it known that I, JAMES U. MITCHELL, of Lancaster, in the county of Coos, of the State of New Hampshire, have invented a new and usefulImprovementinRailway-CarCouplings; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 a longitudinal section, of the draw-bar and front portion of the body of a carprovided with my improved coupling. Fig. 4 is a top view of the coupling-link.

The nature of my invention is duly defined in the claims hereinafter presented.

In the said drawings, A denotes a portion of the front end of a car, while B is a draw-bar below such.

The link-pin is shown at C as going down through the draw-bar and its mouth, and provided with a pawl, D, the latter being hinged to such pin and shaped and furnished with a friction-roller, d, as represented. The link-pin, when at its lowest position in the draw-bar, is supported by the head I) of the pin, which then rests on the top of the draw-bar. In the lower part of the flaring mouth 0 of the draw-bar is an inclined plane, E, for the roller (Z to bear upon, and above the said inclined plane and in the month of the said draw-bar is another inclined plane, F, whose purpose is to guide and force the link down to the plane E when necessary.

The head b of the pin is grooved to receive the forked ends of two levers, G, fulerumed to the car end portion A and arranged therewith, as represented. Each lever passes through one of two staples or straps, I, h'xed to the car, and provided with holes h to receive a pin, 1', to hold down the outer arm of the lever when it may be desirable to keep the link-pin in a raised position.

Besides the levers, I have a chain, K, fixed to the link-pin and to reach to the top of the car, such being to enable a person on such top (No model.)

to raise the pin for uncoupling the car from another car.

The front end of the pawl D is inclined to the plane E. When a link enters the mouth of the draw-bar the entering end of such link will be forced against the said inclined plane, and also against the said inclined end of the pawl, and as a consequence the pawl will be moved up the inclined plane, and in so doing will force the pin upward and allow the link to pass underneath the pin and in rear of it far enough for the pin and the pawl to fall down Within the link and connect it with the drawbar.

The levers are to enable the raising of the pin to be effected without the necessity of a person going between the cars, whereby he would be liable to be crushed or injured in the process of coupling them.

Within the throatof the draw-bar is aspring, I, which, formed and arranged as shown, is to hold the link in a horizontal or proper position for it to entera draw-bar for coupling the latter to it. The link, in being forced into the draw-bar, passes under the spring, which, resting on the link while the latter rests on the bottom of the throat, holds the link in its horizontal position.

hat I claim as my invention is as follows, viz:

1. The combination of the draw-bar B, provided with the inclined plane E, with the linkpin C and the elevating-pawl D, hinged thereto, all being arranged and to operate substantially as set forth.

2. The combination of the draw-bar, provided with the two inclined planes E and F, with the link-pin and its elevating-pawl D, all being arranged, adapted, and to operate substantially as set forth.

JAMES C. MITCHELL.
