MICHAEL ORAMER, OF WHITEWATER, VVISOONSIN, ASSIGNOR OF ONE- THIRD TO JACOB J. STARIN, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 320,335, dated June 16, 1885.

Application filed April 27, 1885.

To all whom it may concern.-

Be it known that I, MIoHAnL CRAMER, of Whitewater, in the county of 'Walworth, and in the State of Wisconsin, have invented certain new and useful Improvements in Car- Couplings; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to carcouplings; and it consists in certain peculiarities of construction, as will be more fully set forth hereinafter. t

In the drawings, Figure l is an end view of a box-car with myimproved coupling attached thereto. Fig. 2 is a perspective view of the lever-rod detached; and Fig. 3 is a longitudinal vertical section of the drawbar head, showing the link and springin place.

My device is equally well adapted for flat- 0.:15 as for box-cars, though I have shown the former in my drawings, in which A represents the end of a car, and a a are cars or projecting lugs fastened to the sides thereof, and perforated for the reception of the leverrod B, which has its bearing therein. This rod (shown in detail in Fig. 2) has a crank-arm, b, at each end, the outer end of each arm being connected by a chain, c, to the side of the car. From the center of the rod B there projects outward, at nearly a right angle to the arms I), a lever, B, terminating in the fork b b, the tines of which extend preferably downward, parallel with the arms I) in inclination, and likewise perforated at their outer ends.

D is the draw-bar, provided with the usual longitudinal perforation, e, in its head for the reception of the link E, and the vertical perforation ffor the coupling-pin F; but the opposite sides or surfaces of the perforation f are provided with vertical grooves 9, extending from the perforation e upward nearly but not quite to the top of the draw-bar for the reception of the ends of the spring G, all as best shown in Fig. 3. This spring (of stout elastic wire) rests on the link E, as shown, and serves to keep it in horizontal position for coupling, the spring being in shape like a partly curled-up hair-pin, the head resting up against the inner upper part of the horizontal perforation e, and each leg or tine resting on one side of the link E, while the free ends of the spring are inserted within the described grooves g, for which reason the spring always (No model.)

remains substantially in place whether the link is in the draw-bar or not, though of course occupying a somewhat lower plane in the latter case. The top of the pin F is perforated, and the pin is thereby held with its head between the forks of the lever B by a rod, pin, or short bolt, f, and when my device is used upon box-cars, as shown in the drawings, or cattle cars, &c., a vertical rod, 0. is pivoted to the projecting end of the boltf, and passes up to the top of the car, where it is secured, so that in uncoupling (or coupling) the pin F can be manipulated from the top of the car (the rod 0 being rigid and continuous) as well as from the sides by the crank-arms b of the leverrod B.

In applying my device to fiat-cars I do not use the rod 0, and my coupling is especially well adapted for flat-cars because as the lever B is normally horizontal it will be with the lever-rod B wholly out of the way of projecting ends of logs, lumber, &c., such as are frequently loaded upon cars of this description. The chains 0 serve to limit the upward movement of the crank-arms b, so that they may be turned up exactly far enough to release the pin from the link without having to estimate or calculate the distance, that being determined the moment the chain becomes taut, which is an important saving of time and trouble.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car coupling, the combination ofthe draw-bar D. having vertical perforation f and longitudinal perforation c, and grooves g in the sides of the perforation f, with the curved double wire spring G, whose free ends rest within the grooves g, substantially as set forth.

2. In a car-coupling, the combination of the car-body and perforated lugs attached thereto with the draw-bar 1), pin F, leverrod B B, having crank-arms b I) and the chains 0 c, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of \Vis cousin, in the presence of two witnesses.

MICHAEL CRAMER.
