WILLIAM F. JULIAN, OF MEDORA, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 313,871, dated March 17, 1885.

(No model.)

To all whom, it may concernw Be it known that I WILLIAM F. JULIAN, a citizen of the United States, residing at lWIedora, in the county of Jackson and State of Indiana, have invented certain new and useful Improvements in Oar-Couplings; and I do declare the following to 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, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part of this specification.

This invention relates to devices for coupling and uncoupling railway-cars; and its object is to avoid the necessity for the operator to go between the cars. In the center and length of a draw-bar I place a disk-wheel held upright by grooves attached to the floor and ceiling and inclined to the mouthof the drawbar, so that whenever the coupling-pin is lifted the wheel rolls under it by force of gravity, and supports it till a blow from an entering link forces the wheel up its inclined grooves and permits the pin to drop through the link, the wheel then rolling back against the pin. The space between the floor-groove of the wheel and one wall of the draw-bar is occupied by a step formed on said floor, which acts as a back-stop to the link. The corresponding space on the opposite side of the floorgroove is filled by a horizontal pawl pivoted to the walls in the back part of the draw-bar, and which also serves as a back-stop to the link; but said pawl is prolonged into a finger which projects over and rests upon one of the long segments of the link, and thus keeps it centered or in a horizontal position ready to enter the draw-bar of an approaching car. A dome is placed on the front part of the drawbar, into which the coupling-pin rises, and which protects the contents of the draw-bar from the weather.

In the accompanying drawings,wherein like letters represent like parts, Figure l is a floor plan of the draw-bar, showing the relative positions of gravity-wheel, backstop, and pawl. Fig. 2is an interior side elevation with back-stop removed, showing the wheel,

grooves, pawl, pin, and dome. Fig. 3 is a de tached side View of the pawl, resting on the link to center it.

A is the floor of a draw-bar; B, the diskwheel; 0, thebottom groovethereof; D, avertical bar to prevent the wheel from being driven too far back; E, the back-stop; F, the pawl; G, a recess in the floor to receive the point of the couple'pin; H, the upper groove; I, the coupling-pin with shoulder 1; to prevent the pin being pulled through the dome K. A shoulder, la, is formed on the dome to serve as a brace for the draw-bar against the edge of the car-platform.

Having thus described my invention,what I claim to be new and useful, and desire to secure by Letters Patent, is the following:

The combination, in car-coupling mechanism, of a draw-bar having a dome, K, grooves O and II, bolt D, and recess G with the wheel B, the back-stop E, the pawl F, and the coupling-pin I, all in the manner herein described, whereby the coupling of two adjacent cars can be performed from the platform, roof, or side of a car, as hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WVILLIAM F. JULIAN.
