CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 565,689, dated August 11 1896.

Application filed January 2, 1896- Serial No. 674,139. (No model.)

To aZZ whom if; may concern.-

Be it known that I, WiLLIAM E. Pnnnson, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Oar- Couplings, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of carcouplings that are self-coupling; and it consists in a device by which the hooking-j aw of the coupling may be readily unlocked without requiring the attendant to place himself i between the cars, the object being to add to the certainty of working of the coupling and to save the attendants from placing themselves in dangerous positions. These objects I attain by the mechanism shown in the accompanying drawings, in which Figure 1 is a horizontal section showing one of the couplings in full lines and the other in dotted lines. Fig. 2 shows in side elevation the head of one of the couplings, a part being represented as broken out to show the construction of the locking device. Fig. 3 is a View partly in vertical section and partly in elevation.

In the drawings, A A A represents the body part of one of the couplings.

B B is a yielding jaw pivoted to the body part at B and held in place by the spring 13 The hooking-jaw H H is pivoted at II and is free to swing outwardly on the pivot II when not locked. An opening H is made in the hooking-jaw H for convenience when. a link has to be used. The coupling-link is held by a pin which passes through the hole II.

The locking device consists of a block P, which is rigidly attached to a pin P, the pin P being free to slide up or down, taking with it the block P. The upper rear part of the hooking-j aw H is cut away, as indicated at H, so that it can freely turn or swing outwardly and unlock when the block P is raised up, as shown in Fig. 3; but when the block P is lowered, as shown in Figs. 1 and 2, then the Shoulder H at the rear of the hooking-jaw will engage with the block P, and the hooking-jaw will be firmly locked in place.

My device for raising the block P consists of a rotatable shaft 0, said shaft having at its inner enda boss 0 and a bent lever-arm 0 This bent lever-arm 0 extends downward, as shown in Fig. 2, the extreme end remaining below and away from the block P when the said block is in its locking position. To cause the block P to raise up and unlock the hooking-j aw H II, the attendant has simply to place the bent end of a hand-rod into the hole 0' in the shaft 0 and turn it, causing the bent lever-arm C toswing under the block P and raise it up away from the shoulder H as shown in Fig. 3, and leave the hooking-jaw I-I free to swing outwardly and uncouple.

When the jaw His in its open position, the block P rests on the top of the shoulder H, but as soon as the hooking-jaw swings in to engage with the corresponding jaw on the other car then the block P falls into its looking position and the cars are self-coupled and locked.

I claim In a car-coupling the combination of a raise the said locking-block substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 30th day of December, A. D. 1895.
