CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 347,511, dated August 17, 1886.

Application filed June 18, 1886. Serial No. 205,548. (No model.)

To all whom it may concern:

Be it known that 1, JAMES H. POLLABD, of Clarence, in the county of Shelby and State of Missouri, have invented a new and Improved Oar-Coupling, of which the following is a full, 4

either side of the car or from the top of the car,

thusobviating the necessity of train-men standing between the cars and exposing themselves to injury.

The invention consists in certain novel features of construction and combinations of parts of the car-coupling, all as hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improved coupling and the adjacent part of a car to which it is attached, and with the coupling-hook down and a link (supposed to be held by an approaching car) about to enter the draw-head to be coupled automatically. Fig. 2 is a like view showing the link in the draw-head and the coupling-hook about to fall through it, and also indicating in dotted lines how the coupling-hook may be raised for uncoupling by a cranked rod extending to the sides of the car. Fig. 3 is a front end view of the coupling. Fig. 4 is a perspective view of the coupling-link, and Fig. 5 is a perspective view of the cranked rod for operating the coupling-hook by hand.

The draw-head A of the coupling is fitted to slide on the car-body B with any suitablyarranged buffer-springs to sustain the shocks of coupling as the carscome together, and has a shoulder at a to limit its inward movement. The link-receiving socket O of the draw-head extends backward to the line 0, to prevent fur ther backward movement or entrance of the end of the link D of an opposing car, and-the front end of the draw-head is flared on all sides around the link-socket to facilitate the entrance of the link 1). In a vertical slot, a,

made through the draw-head there is arranged on its pivot e a coupling-hook, E, which hasa forward pendent horn, e, which is to engage the coupling-link, and a rear arm or part, c", which is adapted to be struck by the entering link in effecting the coupling, and as presently explained. In the floor of the link-socket 0 there is journaled a roller, F, which has two pins, ff, fixed in it and spaced sufficiently to allow the horn e of the coupling-hook E to pass freely between them, and to the roller F is connected one end of a chain or cord, G, the otherend of which is attached to the extremity of the arm 6 of the couplinghook. A plate, H, is pivoted to the lower forward end of the draw-head, and is provided with an arm, h, on which a counterbalance-weight, h, is hung, and may be adjusted to balance the outer part and upper face of the plate H higher or lower, for raising up the drooping endof a link approaching the draw-head and guiding it safely into the draw-head. The plate H will be swung backward unharmed as the two draw-heads strike each other.

To the car-body there is journaled in suitable bearings, i, a transversely-ranging rod, I, which has a cranked arm, J, at its central part, and extending into the draw-head slot to behind the arm (5 of the coupling-hook E, and whereby, as the crank-arm J is thrown forwardby turning the rod I, as in dotted lines in Fig. 2, by swinging back either one of the handle-arms t" or i of the rod at opposite sides of the car, the horn c of the hook will be raised to allow the link D to be pulled from the draw-head for uncoupling two cars and without requiring the train-men tostand between the cars and expose themselves to inj ury. A chain or cord, K, connected to the outer end of the coupling-hook E, passes through suitable guide eyes or loops, as at 76, and runs to the top of the car, to allow the hook to be raised by a man on the top of the car to uncouple two cars in this way when desired. The coupling-hook normally falls by its own weight, when the extremity of the horn e of the hook rests in a recess, a in the floor of the link-socket C, and when the upper end of the hook may fall against the draw-head at the front end of its slot a, all as shown in Fig. 1 of the drawings.

At the sides and front the draw-head is pro vided with laterally-extending lugs L L, providing a space at M to receive the ends of spare links D, which may be held to the drawhead by pins N, passed through the ends of the lugs, and allowing a spare link to be easily removed should it be required for use.

I make the coupling-link D with its lower face rounding or eonvexed lengthwise of the link, and the ends of the link at its upper face will preferably be rounded over a little, as clearly shown in Figs. 1, 2, and 4 of the drawings. hen the coupling-hook E falls, it will draw upon the chain or cord G and turn the roller 1* so its pins ff project forward and upward, as in Fig. 1, and when the link D approaches for coupling on another car the link will strike the pins f and turn the roller F, and thereby draw on the chain or cord G and lift the horn e of the coupling-hook, to allow the end cross-bar of the link to pass behind the horn e and strike the rear arm, 0 of the hook, and thereby force'the horn a downward within the link to effect the coupling, the pins ff of roller F then standing within the link.

To uncouple the cars either the crank-arm I .I or the pull chain or cord K will be operated to lift the horn c and allow the link to escape from the draw-head, as hereinbefore explained.

By the extension of slot at through the bottom of the draw-head dust and dirt may escape from the link-socket or will not lodge therein to interfere with the proper working of the coupling-hook and its connections.

It will be noticed that as the coupling-link cannot pass back of the end 0 of the linksoeket the arm a of the coupling-hook and the crank-arm J cannot be broken by pressure of the link against them.

For coupling ears having draw-heads of diii'erent heights, a coupling-link bent fiatwise in the center and having opposite ends in different horizontal planes will be used, as will readily be understood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is e 1. In a car-coupling, the combination, with the draw-head A, provided with a link-socket, C, and a vertical slot, a, extending behind the end 0 of socket C, of acoupling-hook, E, pivoted at e in the slot c, and provided with a link-confining front horn, e, and a rear arm, 0 substantially as shown and described, whereby the entering link will pass the raised horn e and strike the arm e to-lower the horn, and without danger of breaking said arm 0 or the mechanism behind it, as set forth.

2. In a ear-coupling, the combination, with the draw-head A, having a link-socket, G, and a vertical slot, a, of a pivoted coupling-hook, E, provided with a born, c, and arm 0', a roller, F, journaled at the floor of the link-socket and provided with pins ff, and a chain, G, connecting the roller F with the arm a" of the coupling-hook, substantially as described, for the purposes set forth.

3. In a car-coupling, the combination, with the draw-head A, having a linksocket, U, and a vertical slot, (0, and a coupling-hook, E, pivoted at e in said slot, and provided with a link-holding horn, c, and a rear arm, a", of a red, I, journaled across the car-body, and having a crankarm, J, projecting into the drawhead (6' behind the arm (1 of the couplinghook, substantially as described, for the purposes set forth.

4. In a car-coupling. the combination, with a socketed drawhead, of a link lifter and guide, as at H, pivoted to the draw-head and provided with a counter-balance, substantially as shown and described, whereby the linklifter may be held at any required angle to catch and guide the link of an approaching car, as set forth.
