UNITED STATES PATENT Grinch,
HUGH GRAHAM, OF DARTMOUTH, NOVA SGOTIA, CANADA.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 300,863; dated June 24, 1884.
Application filed December 7, 1883.
T (0Z7 whom it may concern:
Be it known that I, HUGH GRAHAM, of Dartmouth, in the county of Halifax, Nova Scotia, Canada, have invented anew and Improved Oar-Ooupling, of which the following is a full, clear, and exact description.
My invention consists of sliding blocks and springs in the sockets of the draw-bars, to hold the links up level and to hold up the coupling-pins for self-coupling, said sliding blocks being contrived with spring-latches, by which they may be readily set either for so holding up the links or the pins, and the coupling-pins are fitted with stays to hold them upright suitably for dropping when the blocks are tripped from under them, and also with cords and pulleys, contrived for pulling the pins up to uncouple the ears without going between the cars, all as hereinafter fully described.
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 longitudinal section of a couple of draw-bars contrived with my improved carcoupling, and Fig. 2 is an end elevation of a box-car with the said coupling devices applied to it.
I arrange the sliding blocks a in the linksoekets b of the draw-bars c, with springs d behind them to press the blocks forward either to hold up the link e, as at the right hand of Fig. 1, or to hold up the pin f, as'at the left hand of said figure, and in order to set the blocks properly I construct them with three notches, g, in the under side, and provide a stop-latch,j, in the under side of the drawhead for each block, which is constantly pressed up against the block to engage one of the notches by a spring, 1), said spring-stop having a ring, 70, in the end in which to insert the end of a rod for pressing down the latch when the block is to be allowedto be shifted forward by its spring. When the blocks are to be set for holding up the links to enter the draw-bar of the car to be coupled on, the blocks are to be held by the middle notch, h, and when they are to be' set for holding up the pin said blocks are to be held by the; rear notch, z.
IVhen the cars are coupled, the links force (No model.)
the blocks back to be engaged by the catches j in the forward notches, y, where they remain while the cars are coupled. When it is desired to set the link for self-coupling, the stoplatch is pulled down, and the block is allowed to be thrust forward until it strikes the coupling-pin over the end of the link, the block being notched at Zfor allowing it to so pass over the link.
To set the block for holding up the coupling-pin, it is allowed to slide forward till it is engaged by the stop-catch in the rear notch, z, where it remains until the cars run together, when the link thrusts it back.
Together with this improved contrivance for selfcoupling I provide stays m to hold the pins upright and guide them properly when falling, and also provide cords n for raising up the pins to uncouple and set them for selfcoupling, said cords extending from the pins up over guidepulleys 0 on the end of the car -body, and thence down to the lower'outer corners of the car-body, where they may be hung on studpins or hooks, to be within reach from the side of the car for uncoupling without going between the cars.
If preferred, the bar for pulling down the latch j may be connected to the lower end of So the latch in the place of the ring k, and the bar may extend to both sides of the ear to operate the latch from either side.
Having thus fully described my invention,
desire to secure by Letters and also having a stay, m, to hold it upright,
said pulleys 0 being located above the coupling-pin, and the cords being extended to the lower corners of the car-body, substantially as described.
HUGH GRAHAM.
