Description
UNITED STATES JOHN ORIST, OF TIFFIN, OHIO.,
,IMPROVEMENT IN (EAR-COMPL!NGS.l
Specification forming part of Letters Patent No. 142,209, dated August 26, 1873; application filed April 16, 1873.
To all whom it may conccrm' Beit known that I, JOHN GRIsT, of Turin, in the county of Seneca and State of Ohio, have invented a new and useful Improvement in Oar-Oouplin gs and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure lis a longitudinal sectional elevation of my invention shown under two modiications and Figs. 2 and 3 are horizontal sections, respectively, of each modification.
The invention relates to automatic car-couplings wherein the link lifts a catch-hook by its own forward movement; and consists in attachin g said hook to a bar pivoted at the rear end, held down by a spring, and lifted by a vertical rod. It also consists in a novel and effective mode of raising the lift-rod, as hereinp after fully. described.
In the drawing, A represents the draw-head, in the rear part of which is pivoted the catchhook B that holds the link of coupling, and is held down by a superposed spring, O, the lower end of which rests in a countersink of a hole made through the catch-hook. Thisca-tchhook B is apertured vertically at b, has a recessed seat, b', and receives therethrough the lift-rod D, that is provided with a loose collar, d, upheld by apin, d. This rod is pivoted at the lower end to a treadlc, E, fulcruxned in a pendant, F.
The link, pressing against the inwardly-beveled end of hook, raises thc catch B, enters the draw-head A, and the cars are then automatically coupled by the reaction of spring C. In order to free the link from the hook of catchbar B, it may be lifted by hand or by various forms of mechanism, of which the treadle is one. I, however, preferably apply a spiral cam,
G, to the lift-rod, so that by turning the same it moves up or down on a spirally-inclined surface, G', in the bottom of draw-head.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The catclrbar B, having at about the middle thereof a countersunk hole, the countersink being at the top, in combination with spiral spring C and lift-rod D, which passes through the catch-bar, and has bearing-supports in the top and bottom of the drawbar, as and for the purpose specified.
2. The combination of the vertical rod D, cam G, and spirally-inclined surface G in the draw-head with the catchbar B, as and for the purpose specified.
JOHN GRIST.
