UNITED STATES PATENT Q FICEQ JOHN A. WHITTEMORE, OF SPRINGFIELD, MASSACHUSETTS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 265,903, dated October 10, 1882.

Application filed July 8, 1882.

To all whom it may concern:

Be it known that I, JOHN A. WHI'ITEMORE, of Springfield, county of Hampden, State of Massachusetts,haveinvented anew and useful Improvement in Safety-Couplers for Freight- Oars, which is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a plan view of my improved safety-couplcr; Fig. 2, a vertical section thereof.

The draw-head D is provided with a mouth, which terminates at the back in an enlarged chamber, as shown by dotted lines, Fig. 2. In the lower side of the draw head is formed a chamber, 01, and extending from this chamber to the top of the draw-head is a channel, 1), preferably inclined, in which is loosely seated the long arm of an L-shaped pull-bar, B, the short horizontal arm of which is connected to the shank of aT-shaped lifter, A, which shank is square in cross-section, and has vertical movement in a similarly-shaped channel, a, connecting the chamber 01 with the mouth of the draw-head. The horizontal bar or head of the lifter A is cylindrical in cross-section, and is seated, when the litter and pull-bar are in their lowest position,in a groove cutacross the upper end of the channel a, and parallel with the face of the draw-head. This groove is of sufficient depth to allow the upper surface of the head of the lifter to lie flush with the lower wall of the mouth of the drawhead. In consequence of the angular cross- St'CtlOIldl contour of the channel a and of the shank of the lifter A'the latter will be prevented from turning, so that the head thereof will always enter the groove when lowered to its lowest position. The draw-head is provided with the usual pin-hole and couplingpin, and to the rear of the pin-hole is a slot, in which is pivoted an upwardly-projecting weighted dog, G, the free upper end of which falls forward in its slot when the pin is raised, and supports said pin in this position. This dog is movedbaok to release the pin by the (No model.)

entrance of the coupling-link F within the draw-head. The upper end of the pull-bar .B may be connected with any suitable means by which it may be operated from the side of the 'car, though I prefer to use the chain 0 and lifting-shaft E represented in the drawings. This lifting-shaft is provided with an arm, to the end of which one end of the chain is secured, and isjournaled in suitable bearings secured to the end of the car-body. It is of sufficient length to be easily reached from the side of the car, and is fitted on either end with a crank or handle, by which it may be turned to raise the pull-bar B and lifter A when it is desired to raise the coupling-link F and guide it into the mouth of the draw-head of another car.

It will be seen that as thepull-bar and litter are entirely inclosed by the. draw-head they will not be liable to be bent or broken by contact with other objects.

It will be readily seen that by this arrangement an attendant is enabled to lift or lower the link to guide it into the draw-head of another car without rendering it necessary for him to go between the cars, as the crank or handle of thelifting-shaftcan be easily reached from the side of the car.

Having thus described my invention, what I claim is- 1. The combination, substantially as before set forth, of the draw-head provided with channels a b, the litter, the shank of which is arranged to slide in channel (0, and the pullbar connected with its short arm to thelifter, and having its long arm arranged to slide in channel I).

2. The combination, substantially as before set forth, of the draw-head having the channels a I), the lifter, the pull-bar connected thereto, the chain, and the lifting-shaft.
