JAMES EVERETT BULL, OF TRACY CITY, TENNESSEE.

a. CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 404,463, dated June 4, 1889.

To all whom it may concern:

Be it known that 1, JAMES EVERETT BULL, a citizen of the United States, residing at Tracy City, in the county of Grundy and State of Tennessee, have invented new and useful Improvements in Oar-Couplings, of which the following is a specification.

The invention relates to improvements in automatic car-couplers; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a central longitudinal section of the end of a car with a draw-head embodying the invention attached. Fig. 2 is an end view of the car with said drawhead attached.

Referring to the drawings by letter, A designates the end of a car, and B the draw-head attached thereto. The draw-head has the 1011- gitudinal recess 1), of proper size and conformation, and has in its rear end wall a central longitudinal opening for the passage of the long bolt 0, the head of which rests against the inner end of the recess 1), ancLthe shank of which acts as a draw-bar, beingsurrounded by a coiled spring 0. The draw-head has in its floor a recess D for the point of the coupling-hook, and in rear of said recess is the stop projection d for the entering end of the link E. The inner surface of the floor of the draw-head inclines downward and outward, as at e, from the recess D, in order to permit the link to assume an inclined position to couple with a draw-head attached at a lower position on an opposing car.

F is the coupling-hook, provided with the downWardly-eXtending nose or point f, of suitable shape to engage in the recess D after passing into the link, the downward extension f having a rounded end and pivoted concentrically within the rounded recess f in the floor of the draw-head and extending downward from the recess b, and the longitudinal inward projection f 3 extending into the rccess b and pressed upward by the upper leg of the spring G,- secured by a transverse pivotal bolt g in rear of the coupling-hook, and with its lower leg 9 bearing upon the floor of the recess 1) of the draw-head.

H is a transverse shaft journaled in bearings h, secured to the end of the car above the draw-head, and having the crank-arms h Application filed September 18, 1888. Serial No. 285,735. (No model.)

it at its ends on the outer sides of the car, so that the brakeman can rotate said shaft from either side without going between cars.

I is a chain or rope having its upper end secured centrally to the shaft H, and its lower end attached to a staple 2', secured to the coupling-hook on its upper side nearits outer end.

It is obvious that when the shaft H is rotated and the chain I wound thereon the coupling-hook will be lifted out of engagement' with the link. When the nearer and approaching end of the link strikes upon the incline e of the draw-head, it rides up thereon and strikes against the front edge J of the point of the coupling-hook, which edge inolines downward and inward. On account of said inclination the end of the link raises the point of the hook and passes thereunder. I/Vhen the link has passed in, the said point is forced by the spring G through the adjacent end of the link and engages in the recess D, thereby coupling the cars.

The point of the coupling-hook, when in the link, tends to hold the latter horizontal, but not so firmly as to prevent it beingturned up or down to couple with a draw-head of different height.

WVhen the coupling-hook turns up, its outer end passes up through an opening in the top of the draw-head. Having described my invention,I claim- The combination, with the draw-head B, longitudinally recessed, as at b, and having a vertically-communicating recess, and having the bottom recesses D and f of the hook F, having the end f fitting in the recess D and the depending portion f pivoted in the recess f and extended to form the rearwardlyprojecting shoulder f and of the transverse shaft 9, mounted in the rear end of the longitudinal recess 1), and the V-shaped spring G, having its angle bent to form a shaft-embracing eye, and one terminal bearing against the bottom of the recess 1) and the other against the under surface of the shoulder f of the hook, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

' JAMES EVERETT BULL.
