REUBEN F. KROHN, OF SUNBURY, PENNSYLVANIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,840, dated March 23, 1880.

Application filed January 6, 1880.

lb all whom it may concern Be it known that I, REUBEN F. KROHN, of Sunbury, in the county of Northumberland I and State of Pennsylvania, have inw'ented a new and Improved Gar-Oouplin g, of which the following is a specification.

Figure l is a plan of the device. Fig. 2 is a longitudinal sectional elevation on line as m, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a simple and effective self-coupler whereby cars can be coupled or uncoupled and the link removed Without going between the cars.

In the drawings, A represents a draw-head provided with a central longitudinal opening, a, in its top, within which is pivoted, on the pin 0, the curved latch or tongue B, whose upper surface is flush with the top of the drawhead and whose under surface curves downward, as shown, and rests on the lug 0 below it. C is a triangular lug, rigidly fixed with its point forward just within the mouth of the draw-head A, as shown, with the short face of the said lug undercut, as shown at 0, looking rearward. On a parallel line with this lug O, and rearward of it, in the draw-head A, is rigidly fixed the triangular lug D on the bottom of the said draw-head. This lug D is somewhat lower than the lug C, has its short face undercut, as shown at d, and is set a short distance from the lug (J and facing it, so that between the two lugs there is an opening or socket, f, shaped somewhat like an egg, with a narrow opening, g, in its top for the admission of the coupling-link E.

On either side of the opening a, near the mouth of the draw-head A, and passing down through the top plate to the lower plate thereof, are the pins F, that serve as guides for an entering link, and may (either of them) be also used to hold the link in the event of the breaking of the lug U.

The end of the link E, entering the drawhead between the pins F, will, in coupling, move up the inclined face of the lug C to its highest point, pushing up the tongue or latch B in the latter part of its progress, and as soon as the end of the said link has passed the tip of the said lug O the weight of the tongue or latch B forces it (the link) down through the opening 9 into the socket f between the lugs (J l), whence it is prevented from drawing out by the lug G and prevented from moving rearward by the lug D.

A car can be uncoupled and the link E removed through the opening a on turning the tongue or latch B back, as shown on the right in Fig. 2, avoiding the trouble and danger of going between the cars for such purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patout-- A car-coupler having the oppositely-concax'ed lugs O c D d, forming the socket j g, the guides F F, and the rear hinged tongue, B, supported on the more elevated front lug, O, as shown and described.
