IMPROVEMENTi IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 148,370, dated March 10, 1874; application filed December 1, 1873.

To all whom it may concern;

Be it known that I, AARON K. KLINE, of Readington, in the county of Hunterdon and State of New Jersey, have invented a new and Improved Car-Coupling, of which the'followv ing is a speciiication:

The invention will rst be fully described, and then pointed out in the claims.

Figure 1 is a longitudinal -sectional elevation of a couple of draw-heads with my improved coupling contrivance represented as coupled together. It also shows portions of the platform or car-bottoms dotted. Fig. 2 is a section of one of the draw-heads, showing the method of setting the coupler for coupling self-actingly; also, the method of uncoupling;

and Fig. 3 is a plan view of one of the draw- In order to uncouple the cars without goin g between them, I now propose to employ a depressing-lever, F, for forcing the inner end of the coupler down, in the manner indicated in Fig. 2 3 for raising the opposite end of the coupler out of the draw-head; also for tilting it up so that it will slide inward and engage its end Gr under the catch H, to hold the coupler up level for coupling self-actingly, and, to operate the lever, I propose to have a double pawl, I, arranged above it on a cranked rockshaft, J, which may be turned by the operator standing at the side of the car or on the platform, or a rod may extend from the crank K up to the top of the box-car, to enable one on the top to operate it. The pawl is made double to throw the lever back again-also, in case it should fail to go back-although it will be weighted for that purpose; but, as it' is subject to considerable jarring by the motion of the cars, it might not, in all cases, respond to its weighted end. The pawl might be dispensed with, and the lever F applied directly to the cranked rod, but it is desirable to have thelever independent of the rod, in order that its trunnions or pivots L may be arranged in elongated cavities M, slightly descending. toward the front of the draw-head, to hold the-lever in the forward position, and allow it to slide back a little under the influence of the backward pressure of the pawl, when turned well down, to aid the coupler in sliding back to be caught by catch H, and to accommodate itself to that motion. The catch H may be formed of a bent rod cast in the draw-head, as here shown, or by a llat piece bolted on the bottom M behind the cavity O, and projecting beyond it. Behind the cavity O is a long chamber, Q, for receiving the coupler, and retaining it for use, in the bottom of which I have arranged a cavity, I), for the head at the front end of the coupler to drop into, to secure it against working out. The coupler is prevented from swinging laterally, when held up for coupling, by the shoulders B, and a little notch or bend in the under side of the catch H.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the draw-head A of a lever, F, for uncoupling and for adjusting the coupler for self-coupling, the lever being worked directly by the crankedrod J, or by a pawl, I, on said rod, substantially as specified.

2. The said lever F, arranged to slide back on its pivots o r bearings, to allow and aid theI coupler to slide under the catch H, substantially as specified.
