CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 237,588, dated February 8, 1881.

Application filed November 19, 1880.

To all whom it 'may concern:

Be it known that I, WILLIAM V. PERRY, of Chicago, in the count-y of Cook, and in the State of Illinois, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements in car-couplings; and it has for its objects to provide for holding the coupling-pin in the draw-head in such manner as to be at all times under the control of the operator, whether to couple or uncouple, and to prevent any possibility of losing the coupling-pin. The coupling-pin which I employ is the same as the ordinary coupling-pin of elliptical crosssection, with the exception of the shoulders at the lower end. The draw-head is the same as those usually employed on railroads, with the exception of two chambers situated one on each side of the coupling-pin aperture, near its upper end. The above-mentioned objects I attain by theV mechanism and apparatus illustrated in the accompanying drawings, in which- Figure l, represents a longitudinal vertical sectional view of my improved car-coupling draw-head, showing the coupling-pin in erect position, resting upon any of the usual pinsupports, ready to be dropped home by an incoming link. Fig. 2 represents the coupling pin after being raised to its highest limit and turned one-quarter of a turn either to the right or left, and allowed by its own gravity to stand inclinin g either forward or backward, and resting upon the inclined shoulders near its lower end. Fig. 3 represents a transverse vertical sectional view of draw-head, showing the upper end of the coupling-pin aperture and the recesses therein. Fig. 4 represents a top view of my draw-head with a portion of the lower end of the couplingpin in position, so as to be kept from falling home by the two inclined shoulders holding in the recesses at the opposite sides of the coupling-pin apertures. Fig. 5 represents a transverse horizontal sectional view of the lower part of the coupling-head,

(Model.)

and Fig. 6 represents a view of thecouplingpin detached.

The letter A indicates the draw-heads, which may be of the ordinary or any approved construction.

The letter B indicates the coupling pin, which is elliptical in cross-section.

The letter C indicates the coupling-pin aperture, which is also elliptical in cross section to correspond with the shape ofthe pin.

Near the lower end of the coupling-pin are formed the inclined shoulders D, upon which the pin is adapted to rest when fully elevated and given one-quarter of a turn in either direction.

The letter E indicates two shoulders at the lower extremity of the coupling-pin, which are adapted to engage the recesses F formed on opposite sides of the coupling-pin aperture when the pin is in its elevated position, the said shoulders preventing the pin from pulling out or being accidentally lost when thus elevated.

The letter G indicates the rivet usually employed at the lower end ofthe coupling-pin to confine it in its aperture, when directly elevated, before turning to set the shoulders E in the recesses. The ends of thesaid rivet slide in the grooves H in opposite sides of the couplingpin aperture provided for the purpose. y

The operation of my invention will be readily understood in connection with the above description, and is as follows When the coupling-pin is down it holds the link in the ordinary manner. When elevated it frees the link, and by turning said pin one-quarter of a revolution in either direction it brings the inclined shoulders to bear upon the upper face of the draw-head and throws the shoulders at its extremities into the recesses ais-opposite sides of the coupling-pin aperture, so as to keep the pin elevated and hold it to its seat, as hereinbefore stated.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A coupling-head provided with recesses F F at each side of the coupling-pin aperture, near its upper end, the said recesses being adapted to engage the shoulders on the lower In testimony that I olaim the foregoing I 1o end of the oouplingqiiu, when the same is have hereunto set my hand this 16th day of turned ab right angles to its normal position, November, 1880.
