CAR-couetme SPECIFICATION forming part or' Letters Patent No. 313,968, datediMarch 17, 1885.

Application filed October 27, 1884.

To all whom it may concern.-

Be it known that I, WALTER TURNBULL, a citizen of the United States, residing in the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Car-Coupling, of which the following is a specification.

My invention relates to car-couplings which are operated automatically; and the objects of my invention are, first, to provide a means by which railway-cars can be coupled together automatically without endangering the limbs and lives of railway employs, as also to eX- pedite the operation of coupling up trains of cars; second, to afford facilities by which cars will-beg coupled by a hook when all the cars are equipped with my coupler, also to provided a means by which my coupler will couple automatically with cars equipped with the present link-and-pin coupler, sothat my hook-coupling can be gradually adopted and replace the lpresent link-and-pin couplers as they Wear out; third, to provide a means by which my coupler can be made to suit the fittings of any coupler which it is desired to replace. I attain these objects by the mechanism illustrated in the accompanying drawings, forming part of this specication, in which- Figures l and 2 are respectively a side and plan view of my coupler, showing the coupling made with ears equipped with my coupler. Fig. 3 is a side view showing the coupling made with a car equipped with the present link-and-pin coupling. Fig. 4 is an end view showing arrangement for uneoupling the cars.

Similar letters refer to similar parts throughout the several views.

The buer or draw-head B is provided with recesses in front end to admitof the hook-lever H and the link-lever L, and is also provided With a buffing-plate, P, to keep link from going to far into draw-head. The back part of draw-head is made to conform to the iittings of any other style of draw-head which itmayreplace. The hook-lever H is shaped as shown in drawings, and is secured to drawA head by the pin t, the lever being slotted to admit of ahorizontal movement. This hooklever H is provided with an eyebolt, e, to

(No model.)

`which is attached a chain, c, which is secured to the sheave s' on shaft r, which rod is secured to end of car to lift the hook-lever H to uncouple same, or to hoist the hook-lever up out of the way, so that the link-coupling can be made as shown in Fig. 3.

The link-lever L is secured to draw-head by the pin N, and is provided with a hook h, at its outer end to engage with coupling-link K. It is also provided with an eyebolt, 0, to which a chain, b, is attached, which is secured to sheave s for lifting 'the link-lever L in position to couple with link K, as shown in Fig. 3, also for uncoupling the link.

The shaft r extends across the end of car,and is secured to the car bythe bearings M. The ends of shaft r are bent as shown in Fig. 4, forming handles d, to which are secured counter-weights w to keep shaft r from turning over when it is desired to maintain the hook-lever Hinthe position shown in Fig. 3. The Sheave s is secured to the shaft r and receives the chains b and c. The diameter of this sheave sis such that, when the position of the eyebolts e and o are determined, one revolution of the sheave s will lift the hook-lever H and the link-lever L to the position shown in Fig. 8, `so that a link-coupling can be made, and the hook-lever H and link-lever L are maintained in this position by the bent handles d of shaft r hanging down and having the counter- Weights w.

X is the body of freight-car, showing the relative position of same with the coupler. D is a link-and-pin coupler.

Having thus described the construction of my coupler,the working of same is as follows, viz: When it is desired to couple ears which are equipped with my couplers, the hook-lever H lies horizontal and the link-lever L lies in recess in bottom of draw-head, as shown in Fig. l, and as the cars come together the hook-lever H of one ofthe cars rides over the hook-lever of the other car and falls into position, as shown in Figs. land 2, and, when it is desired to uncouple them, the sheave s is revolved by the handles d of the shaft r and lifts the hook H until the hooks are disengaged, when the car pulls out and the hook-lever H falls back in position to be coupled again.

When it is desired to couple my coupler IOC) with cars equipped with theliiik-andpin coupler, the sheave s on the shaft o is turned once around by the handles d,whicl1 lifts the liooklever H up out of the Way and brings the linkleverLin position to receive the coupling-link K, as shown in Fig. 3. Vhen the link K secured in draw-head D strikes against the an gle end of the link-lever L, it lifts same and rides under it and engages with the hook h. This coupling-link K is uncoupled by turning the sheave s until the hook 7L of link-1ever L disengages With coupling-link K, when the car pulls out and the link-lever L falls back in position to be coupled again.

Having thus described the construction and operation of my coupler, I claim as new and desire to secure by Letters Patentl. The combination, in au automatic carcoupler, of the buffer or dran/head B, provided with the recesses in forward end for the hook-lever H and link-lever L, and the buffing-plate P with the hook-lever H, provided with pint' and eyebolt e, and the link-lever L, provided with the hook h, pin N, and eyebolt 0, all substantially as set forth, and for the purposespeeied.

2. In an automatic car-coupling, the combination of the buffer B, hook-lever H, and linklever L, with the chains b and c, sheave s, shaft a", handles d, bearings m, and counter- Weights w, all substantially as described, and for the purpose specified.

" W'ALTER TURNBULL.
