CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 272,680, dated February 20, 1883.

Application letl December 21, 1882.

To all whom it may concern Be it known that I, EuWIN S. GRAVER, of Philadelphia, in the county ot' Philadelphia and State ot' Pennsylvania, have invented a new and Improved CarCoupling, of which the following is a fnll, clear, and exact description.

My improvement in car-couplings consists, essentially, ot' a loop or U-shaped link pivoted to one draw-bar, in combination with a horn on the other drawbar, with which said link engages by swinging down over the horn, together with a latch device lor holding up the link when uncoupling, and a device lor lodging` the link on preparatory to coupling and throwing it down over the liornand coupling bythe recoil ot' the draw-bar when the cars run together, the said improvement lbeing a simple and efticient device that may be used, together with the ordinary coupling link and pin, on cars ot' any kind and ofditerent heights, and by which the dangerous practice ot' going between the cars to couple them may be avoided, all as hereinafter fully described.

Reference is to be had to the accompanying drawings. forming part of this` specilication, in which similar letters of reference indicate coriesponding parts in both the ligures.

Figure l is a t'ront elevation of a platformcar with my improvtd car-coupling applied, and Fig. 2 is a side elevation.

l use a draw-bar, a, of the common form and arrangement, and having a socket, b, and pin-hole c, for the use of the coininon link and pin when required, and connect the loop or U-shaped link di to it on a raised portion,

- g, a suitable distance back of the end, by a pivot-bolt, c, passing horizontally through the two ends ot` the link and the bar, and being headed at each end, said link being of suitable length to swing forward of the eiid of the draw-bar sut'liciently to drop over a lioin,f, projecting up fiom the end of the draw-bar of the car to' be coupled on, each draw-bar being provided with a link and a hoiii, so that when both links are coupled the couplings willbe double.

lo couple the cars self-actingly with this forni ot'coupling, I provide a plate, g. on the bed or .platform h of the car, and projecting (No model.)

forward overthe draw-bar in suitable relation to the link to allow it to be 'swung over and rested against said plate, as indicated by dotted lines of Fig. 2, for setting the link preparatory to coupling, which plate will thrust the link forward and cause it to t'all down and couple the horn ot' another car when two cars run together and thedraw-bars are forced back against the bulier-springs To hold the link up sufficiently for uncoupling, I arrange a latch,j, on one side ot' the draw-bar, to be swung up and set under a stud, k, ofthe link, as shown by dotted lines iu Fig. 2, to hold the link until the cars are drawn apart, when the link maybe allowed to swing down and hang` trom the pivot-bolt till required to couple again, and being set up against the plate g for the pui-pose.

I propose to avail myself ot' the plate g to serve as a stop by means ot' a sliouluer, Z, ou it, and a shoulder, m, which the raised portion q ot the draw-bar enables inev to provide in suitable relation to the shoulder l for arresting the back-thrust ot' the draw-bar for the pro. tection of the buiierspring from overcom pression.

It will be seen that by the wide space between tlie twol bars ot' the link, required by the manner of applying it to the dra w-bar, the coupling has considerable range for lateral deviation ot' the draw-bars from the centers, and the links will draw properly in going around curves; but to enable the coupling to connect on any curves, no matter how short, I propose to arrange the draw-bars to swing laterally, when required, by arranging them in a supporting-hanger, 0, extended, as indicated by the dotted lines p, Fig. 1, and by suitably pivoting them at `the back connection, t, and in such case will employ a pin, s, to connect them with the plate g when they are notrequired to swing forsuch purpose. This pin may in such case sustain the draftthrough the medium ot' the plate g,- or, if-desired, the draw-bar or said plate may have a slotted hole for it. The link d will be made thicker and stronger in the bow u, Fig. l, than elsewhere, to resist the tendency of' the strain to bend it thereat.

1t will be seen that by attaching` a chain to the link on the tender and suitably leading it into the cal) ot' the engine the engineer can shoulder Z of the plate g, attached to the caul nnconple and conple his engine nt any time .body, substantially as described.

fiom bis place in the cub.

Having thnsdese'ribed my invention. I claim as new and desire tosecure by Letters Patent- 1. The combination of a plate, g, attached to the car-body, with a link, d, pivored to the draw-bar, substantially as described.

2. In a oar-coupling having a link, d, pivio oted to the draw-bar, as set forth, the shoulder l m on said draw-bar, in combination with the 3. In a car-coupling, the combination, with the drew-ber a, having the pivotvd proppingletvlij, of the link d, pivoted to the draw-bai' and provided on its under side with the stud l 7c, substantiallyas and for the purpose set forth.
