CHARLES E. SEABURY, OF STONY BROOK, NEW YORK.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 429,365, dated June 3, 1890.

Application led October 19, 1889. Serial No. 327,571. (No model.)

T all whom it may concern:

Be it known that I, CHARLES E. SEABUEY, of Stony Brook, in the county of Suffolk and State of New York, have invented a new and Improved Car-Coupling, of which the following is a full, clear, and exact description.

My invention relates to car-couplings, and has for its object to provide a simple, inexpensive, durable, and automatic coupling of this character by which two cars may be coupled without requiring the train-men to go between them and expose themselves to injury. The coupling is adapted also to connect with the common link-andpin drawhead.

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

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

Figure lis a vertical longitudinalsectional elevation of portions of two cars coupled by my improved coupling. Fig. 2 is a plan View thereof in horizontal section on the line :r in Fig. l. Fig. 3 is a sectional side view of one coupler, illustrating how the coupling-pin is supported prior to coupling two cars; and Fig. 4 is a top perspective view of the springheld link-block-coupler device.

The draw-head A of my improved coupling has a central cavity or chamber, in which the link-block-coupler device B is held by a coupling-pin C. The draw-head has the usual fiaring or bell mouth, and is preferably cast in one piece of metal, and may be sustained in position on the car-body D by any suitable supports supplemented by buffer and draw springs fitted in the usual or any approved manner. The floor of the draw-head cavity is preferably convexed longitudinally ata at its front portion to allow the link-block coupler B to rock or have vertical play, so as to rise and fall at its forward link or coupling end to accommodate or enter a draw-head of different height on an opposing car.

The coupler device B consists of a rear block portion E, having a hole e to receive the coupling-pin and a front link portion F,

throughl which t-he coupling-pin of an opposing car will fall. 'lhis coupler device is preferably forged solid from one piece of wrought metal; but it may be made of cast-steel, if desired. To the coupler-block E are secured three springs H H I. The springs H H are fastened at their rea-r ends to the back end of the block and extend forward and outward at either side thereof; but the spring' I is fastened to the block at its forward end and eX- tends rearward and upward and rests at its free end against the top or roof of the drawhead cavity, while the two springs H H bear by their free ends upon opposite side walls o f the cavity. The three springs thusnorinally support the entire coupler device E F centrally, both vertically and horizontally, in the draw-head, while allowing ample play up. down, or sidewise to the outer link portion F to accommodate the vertical or horizontal oscillations of the coupled cars.

NVithin the draw-head cavity and at one side thereof is hinged in'any approved manner-by a pin j, for instance-a coupling-pin support J, which has a vertical wall or part adapted to fit into a recess al', made in the side wall of the draw-head, when the support is pushed inward by the advancing link to effect a coupling, as presently explained. This support has an upper ledge portion c, onto which when swung forward the coupling-pin C will rest, as shown in Fig. 3 of the drawings.

Vhile any suitable spring device may be employed to normally throw the coupling-pin support forward into position to thus sustain the pin, I prefer to dispense with springs for this purpose and to provide at the inner face rof the side wall of the draw-head a cavity a2,

into which a mans finger may be passed behind the support to easily draw it forward into position to sustain the pin, and I also vprovide a hole a3 through the side of the draw-head to allow a bar or rod or push-pin device to be inserted from the outside for forcing the coupling-pin support forward to sustain the pin should the support be stuck fast within the draw-head' recess a', so that it cannot easily be drawn forward bythe finger of a mans hand thrust into the draw-head cavity from the front.

IOO

The operation is very simple and eiEective, .s follows: lVe will suppose two cars to be :oupled are provided with my draw-head A, coupling-pin C, and pin-support J. Into one ithe two opposing draw-heads the couplinglink block E F will be placed and held by a coupling-pin C, as shown in Figs. 1 and 2 of the drawings. The pin C of the other coupler will be sustained on the drawn-forward pinsupport J, as shown in Fig. 8 of the drawings and as would be indicated also by the dotted position of the support in Fig. 2, and as the two cars come together the link F will enter the opposing draw-head and strike the pin-support J and push it backward, and the pin C, which it had sustained, will fall through or within the link and automatically couple the cars Without requiring train-men to stand be` tween them and expose themselves to injury.,` Should the car draw-head holding the link` device be higher or lower than the draw-head of the opposing car, the link maybe set lower orhigher, and the pressure of the side springs .l Il H Will so hold it to properly enter theA otherdraw-head and effect the coupling. Any` car provided with the block-link device E F may easily be coupled to another car having;

the common link-and-pin draw-head.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a car-coupling, the combination, with the draw-head, of a link-coupler device placed loosely therein and provided with side springs and a top spring bearing, respectively, on the opposite sides and top of the draw-head cavity, and a coupling-pin passed through the draw-head and link device, substantially as herein set forth.

2. In a car-couplin g, the conibination,\vith a recessed draw-head, of a block-link E F, hav ing a hole e and provided with opposite side springs I-I Il and a top spring I, and a coupling-pin C, passed through the draw-head and the link-block hole e, substantially as dfscribed, and for the purposes set forth.

3. In car-couplings, the coupler device consisting of a rear block E, having a hole e for the coupling-pin and a front link F and provided with opposite side springs Il Il and a top spring I, substantially as herein set forth.

4. In a car-coupling, the combination, with a draw-head recessed interiorly at one side, of a hinged coupling-pin support adapted to said recess, said draw-head also recessed at a2, next the free edge of the'infolded pin-support, to allow the latter to be easily drawn forward by the finger from inside the draw-head, substantially as herein set forth.

5. In a car-coupling, the combination, with a four-walled or inclosed draw-head, of a coupling-pin support hinged Within it, said drawhead having a side hole or opening a3, allowing projection of the pin-support from outside the draw-head, substantially asherein set forth.
