JAMES S; SCOTT, OF NEW YORK, N. Y.

CAR-OOUPLING.

SPECIFICATION forming part of Letters Patent No. 511,278, dated December 19, 1893.

Application filed Augus ifil, 1893. Serial No. 484,506- (No model.)

T or whom it may concern:

Be it known that I, JAMES S. SCOTT, of the city, county, and State of New York, have invented a certain new and usefullmprovement in Oar-Couplers, of which the following is a specification. I will describe a car coupler embodying my improvement, and then point out the novel features in the claims. to In the accompanying drawings Figure 1 is a plan or top View of a car coupler embody- 1ng my lmprovement. Fig. 2 is a side view of the same. Fig. 3 is a perspective view of a plate used in said coupler. Fig. 4 is a top I 5 view of the knuckle 0f the coupler.

Similar letters of reference designate corresponding parts in all the figures.

A designates a coupler head and A- designates a shank extending from the same.

13 designates a knuckle having a main or outer portion 1) and a locking portion 17 said knuckle being pivotally connected with one side or arm of the coupler head by means of a pivot pin 0. The portion 1) of the knuckle may be bifurcated and provided with holes to enable it to be used with the ordinary link and pin.

D designates a vertically sliding pin fitted to a recess a formed vertically in the coupler head rearward of the pivot pin 0 and intersecting a recess a formed in the coupler head. As here shown this pin has a narrow lower portion, a wide upper portion and an inclined surface (Z intermediate of its narrow and wide 5 portions. Not only is this inclined surface inclined in a vertical direction, but it is preferably also inclined horizontally. The extremity of the inner portion 11 of thekuuckle is inclined reversely to the incline of the locking pin. Hence when the inner portion 19 0f the knuckle is swung inwardly and comes in contact with the inclined surface of the looking pin, it will force the lockin g pin upwardly until it has passed the same. Then the looking pin will drop by gravity and as the surfaces of the locking pin and knuckle then in contact are flat, the knuckle will be enabled to raise the locking pin and will be secured by the locking pin.

- E designates a flexible or partly flexible contrivance for operating the locking pin or device and for opening the knuckle. As here shown, it is made entirely flexible and consists of a chain which passes through an eye (1 with which the upper portion of the locking pin is 5 5' provided, thence through an eye in a plate like portion or rib ct of the coupler head, and at the extremity is attached to an arm or appurtenance of the knuckle extending beyond the pivot pin of the same in the reverse direction to that in which the main or outer portion of the knuckle extends from said pivot pin. As here shown, the extremity of the chain connects with a plate G which has a hole through which the pivot pin 0 passes, it being secured in place by said pivot pin. This plate is engaged with the knuckle and in the present instance this engagement is offected by extending a pin g from the plate down into a hole formed in the upper part of 7o the outer or main portion 12' of the knuckle. The extremity of the chain is connected to a pin g extending upwardly from the plate G. The chain may be made fast. to the locking pin, as distinguished from running through the lever.

Obviously by pulling upwardly upon the flexible or partly flexible contrivance E, the locking device will first be disengaged from the knuckle and afterward the knuckle will So be oscillated to theopen position.

It will be seen that by my improvement I provide a very simple and efficient means for engaging and opening the knuckleof a car coupler.

I have filed another application for an improvement in car-couplings, the same having been designated Serial N 0. 485,921, setting forth a somewhat similar construction.

What I claim as my invention, and desire 0 to secure by Letters Patent, is

1. The combination of a coupler head, a knuckle pivotally connected thereto, anda plate or lever pivotally connected with the coupler-head, and engaged with said knuckle 5 for the purpose of operating the knuckle, substantially as specified.

2. The combination with a coupler-head and knuckle pivotally connected thereto, a looking device for said knuckle, a plate or lever rco forthe purpose of operating theknuckle, sub- 10 stantially as specified.

In testimony whereof I have signed my pivotally connected with the head and connectedlto the knuckle and an operating device flexibly connected with the said plate or lever and with the said locking device, snbname to this specification in the presence of stantially as specified. two subscribing witnesses.

3. The combination of a coupler head, a JAMES S. SCOTT. knuckle pivotally connected thereto, and a plate or lever secured in place by the pivot of the knuckle and engaged with said knuckle Vitnesses:
