CAR-COUPLING.

SPECIFICATION forming` part of Letters Patent No. 282,910, dated vAugust '7, 1883.

Application filed January 15, 1883. (No model.)

`tion of twovdraw-heads; in one of which is a spring-actuated jaw, which acts as a support for the coupling-pin until the jaw is pushed back into the coupling-head, and in the other a slotted spring-actuated jaw, which has its outer end so formed Vas to support the link in position ready to couple, as will be more yfully described hereinafter.

Figure l is a vertical section of the two draw-heads and their attachments, which compose one of my couplings. Figure 2 is a detail view of the slotted spring-jaw which supports the link in position. n

A A represent two draw-heads of the usual construction, inside of one of which are placed the two spring-jaws B. Each of these jaws have suitable metallic blocks, C, secured to Vtheir outer ends, and which, when the jaws are forced forward, project a suitable distance beyond the front end of the draw-head.

Upon the shank D, which projects from the rear end of both spring-jaws, lis placed a suitable spring, E, which serves to keep the jaws pressed forward when they are left' free to move. In the extension which is formed on the draw-head is placed a suitable stop of any kind, against which the rear end of this spring abuts, so that when the spring-jaw is forced backward the springv is compressed between the rear end of the jaws 'and the stop. As soon as Vthis spring `is left free to act it forces the two spring-jaws outward, so that they will receive a part of the concussion when the cars run together, and thus ease the jar before the draw-heads strike. Through these two jaws are made the holes G for the coupling-pin to pass through. While the jaws are forced outward by the springY the pin is held in a raised position; but when the jaws are moved backward, as the holes come under the end of the piu the pin drops through them and couples the cars together. Upon the top of this draw-head is formed a suitable guide, II, for the coupling-pin, which maybe Vmade long enough to extend up to the top of a freight-car, or provided with an eye at its upper end, to which a chain may be attached which will reach up to any delsired height, and thus allow' the cars to be jaws in the other coupling, rand the -jaw I Upon this pin will be formed a suit' is forced backward without in any way afv fecting either the link or the pin. As the jaw in the one head comes in contact with the lower jaw in the other the two jaws B are forcedbackward, so as to let the couplingpin fall through the link, which is held downwardby the jaw I. This jaw I also servesto ease the concussion when the cars come together before the draw-heads strike. By the use of the' spring-actuated jaws, slotted so that itcan be moved back and forth over the pin, the link -is always held ready to couple with the next adjoining car. y

Where narrow-gage cars are run over wide tracks they have to use a third rail and in that case the coupling would be to one side of the center, in which case the cars would not couple with a coupling of the kind above described. In order to overcome this objection two side drafts are formed, one upon each side of the central coupling, which would carry the link far enough to one side to couple with the narrow-gage cars. n

Having thus described my invention, I elaim-u Y In a car-coupling, the combination of thel two draw-heads A, the spring-actuated jaw In testimony whereof I affix my signature in B, having the hole. G, and which acts as zu presence of two Witmsses;-

support for the coupling-pin, with the springactuated jaw I7 provided with the slot J, and which has its outer end formed so as to act as a support for the link, both of the jaws having their" outer ends to project beyond the mouths ofthe heads, substantially as shown.
