CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 482,774, dated September 20, 1892.

Application led May 3, 1892. Serial No. 431, 747. (No model.)

T0 all whom it may concern:

Be it known that I, JAMES A. VISWALL, a citizen of the United States, residing at Embarrass, in the county of Waupaca and State of Wisconsin, have invented a new and useful Car-Coupling, of which the following isa specication.

The invention relates to improvements in car-couplings.

The object of the present invention is to simplify and improve the construction of carcouplings, to enable the same to couple automatically and to be uncoupled without necessitating a person going between cars, and to facilitate the coupling of cars having drawheads at different heights.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a portion of acar provided with a carcoupling constructed in accordance with this invention. Fig. 2 is a plan View partly in section. Figs. 3 and 4 are detail perspective views showing different forms of link from that shown in Fig. 1.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

l designates a draw-head having a limited vertical movement and mounted on a car 2 and provided with horizontally disposed spring-actuated jaws 3, which are pivoted at their inner ends and are provided with hooks at their outer ends to engage arrow-headed links 4. The draw-head 1 is provided with a horizontal projecting extension or shelf 5, which is beveled at its middle to guide a link between the jaws 3, and which forms a support for the front end of the jaws. The jaws are pivoted by vertical pins or bolts 6 and are normally pressed together by springs 7, secured to the draw-head at opposite sides of thesame,andhavingtheirinner ends arranged within the draw-head and their outer ends engagingthejawsattheouterendsthereof. The jaws are provided with vertical standards S and are separated to release the link for un coupling by a toggle consisting of a lever 9, fulcrumed intermediate its ends on one of the pins 8 and having its outer end connected with the other pin by a bar 10. The inner end of the lever 9 is connected by a rod 11 with an operating-lever 12, which is fulcrumed at thc bottom of the car, and has its upper end shaped into a handle and arranged within a segmental guide 13,located at the top of the car. The bar 10 is pivoted in a bifurcation at the outer end of the lever 9 and to the pin 8, and the jaws are held partially separated by a projection 14, extending horizontally from the top ot' the draw-head and adapted to have the stems abut against the ends of the same. The jaws may be spread by moving the upper end of the operating-lever toward the adjacent side of the car and turning the toggle, as illustrated in Fig. 2 of the accompanying drawings. The straight links 4 or crooked links 15 may be employed, the latter being used to couple cars having draw-heads of difierent heights, and the link 16, consisting of a narrow head and an ordinary link, may be used to couple a car having the improved draw-head with one having an ordinary pin-and-link coupling. The upper end of the lever 12 is provided with aspringactu ated pawl 17 to engage a notch 18 at the outer end of the ratchet. The draw-bar is keyed in the usual manner, as illustrated in dotted lines in Fig. 2 of the accompanying drawings.

What I claim is- 1. In a car-coupling, the combination of a draw-head having pivoted spring-actuated jaws, a toggle consisting of a lever fulcrumed intermediate its ends on one of the jaws, a bar connecting the outer end of the lever with the other jaw, and an operating-lever connected with the inner end of said lever, substantially as described.

2. In a car-coupling, the combination of a draw-head provided at its top with a proj ection, pivoted spring-actuated jaws mounted on' the draw-head and provided with vertical stems arranged on opposite sides of the proj ection and adapted to abut against the same to hold the jaws partly open, a toggle comprisinga lever fulcrumed on one of the stems, a bar pivoted to the outer end of the lever and to the stem of the other jaw, and an operating-lever connected with the inner end of said lever, substantially as described.

3. In a car-coupling, the combination of a IOO draw-head having a horizontal extension projecting from its bottom and having its outer edge beveled, spring-actuated jaws having their inner ends pivoted in the draw-head and having their outer ends supported by the said extension and provided intermediate their ends with vertical standards, a toggle consisting of a lever fulcrumed intermediate its ends on one of the stems, a bar connecting the 1o outer end of the lever with the other stein,

and an operating-lever connected with the inner end of the other lever, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in r 5 the presence of two Witnesses.
