CAR-COU PLI NG.A

SPECIFICATION forming part of Letters Patent No. 461,540, dated October 20, 1891.

Application led June 6, 1891. Serial No. 395,292. (No model.)

To all whom t may concern:

Be it known that I, ARNOLD HENRY BLANK- MAN, a citizen of the United States, residing at Alton, in the county of Wayne and State of New York, have invented a new and useful Oar-Coupling, of which the following is a specification.

This invention relates to car-couplings, and more especially to that class thereof known as twin jaw, and the object of the same is to effect certain improvements in the manner of operating the jaws.

To this end the invention consists in the specic details of construction hereinafter more fully described and claimed, and as illustrated on the'sheet of drawings, wherein- Figure l is a perspective view taken slightly from the ,under side and showing the end of the car provided with myimproved coupling. Fig. 2 is an end elevation of the car with the draw-head retracted. Fig. 3 is a right side elevation.

Referring to the said drawings, the letter O designates the bod y of the car, beneath which are secured two blocks B, having outwardlycurved adjacent faces F, between which is loosely mounted the enlarged and rounded rear end E of the draw-head D. The latter has at its front end a beveled jaw J of any approved type of twin-jaw car-coupling, and a spring S beneath the car draws the body of the draw-head laterally Within a transverse slot T in the dead-block in aproper direction to cause the jaw .I to engagea similar jaw on another car.

W is a wheel eccentricallypivoted, as at P, to the end of the car above a retaining-stop R, which limits its movement, and the periphery of this wheel is grooved, as seen at G in Fig. 3, a chain N leading from the draw-head partially around the periphery of this'wheel and connecting with an eye I therein. The vertical rod V is connected to a crank-pin K in this wheel about at the -point shown, and its upper end is forked and pivoted to the front end of a lever L, which is mounted on an upright U, rising from the top of the car.

In operation, when the lever is moved bya brakeman standing on the top of the car, so as to depress the rod V, the wh eel XV is turn ed outwardly, as shown inFig. 2, and the tension ofl the chain N as it is wound over the groove G draws the draw-head D to one side within the transverse slot T and disengages the jaw J from a similar jaw on the other car. Upon releasing the lever the spring S causes the parts to assume their norm-al positions. At this time the wheel V has turned so far over its pivot P and rests upon the stop R in such a manner that the draw-head cannot be accidentally or automatically retracted, and hence the undesirable uncoupling of the cars will not take place. Various changes in the details of construction may be made Without departing from the spirit of my invention. When it is desired to remove 'the draw-head for any purpose,its enlarged and rounded head E is dropped out ot' the space between the curved faces F of the blocksfB, andthe entire draw-headand draw-bar is removed longitudinally through the slot in the dead-block. By this specific form of pivotat the rear end of the draw-barI avoid the necessity for using any pivot-bolt,'although of course, if desired, one might be used without affecting the balance of the invention.

Vhat is claimed as new isl. In a car-coupling, the combination,with blocks secured beneath the car-body and having outwardly-curved adjacent faces, a slotted dead-block, a draw-head having an enlarged and rounded rear end looselymounted between said curved faces, its body passing through the slot in the dead-block and its front end having a beveled jaw, and a spring holding said draw-head wit-h its jaw in normally operative position, of means, substantially as described, for retracting the drawhead against the tension of thespring, as set forth.

2. In a car-coupling, the combination, with a draw-head pivotally connected at its rear end with the car and having a beveled jaw at its front end and a spring holding said drawhead With its jaw in normally operative position, of a wheel eccentrically pivoted to the end of the car at the rear side of said drawhead, a stop below said -wheel at a point to allow the longest radius of said wheel to stand between its pivot and the draw-head, and means, substantially as described, for turning said wheel and retracting the draw-head, as set forth.

8. In a car-coupling, the combination, with ICO a. draw/:head pivotally connected at its rear connecting said lever with the crank-pin, as

end with a ear and having a beveled jaw at and for the purpose hereinbefore set foltlL its front end and a spring holding said draw- In testimony that I (claim the foregoing as head with its jaw in normally operative pomy own I have hereto axed my signature in 5 stion, of a wheel eeeentrioally pivoted to the presence of two witnesses.
