GEORGE WILLIAM CURTIS, OF PHILADELPHIA, PENNSYLVANIA.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 234,175, dated November 9, 1880.
To all whom zt may concern:
Be it known that I, GEORGE W. CURTIS, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Gar-Coupling: and I do hereby declare that thefollowing isafull, clear, and exact description of the same.
My invention is an improvement in the class of car-couplings in which the ordinary closed oval link is employed in connection with a coupling-hook which is pivoted and adapted to slide within a draw-head.
Theimproveinent consists in the construction and arrangement of parts, as hereinafter described and claimed.
In accompanying drawings, forming part of this specification, Figure l is a longitudinal section of a draw-head provided with coupling devices according to my invention. Fig. 2 is a plan view, part being broken out. Fig. 3 is a cross-section on line as ac, Fig. 2.
The draw-head A has a narrow lengthwise slot in its upper side, which extends back from its enlarged head I). The slot allows the coupling-hook B to rise as required, to engage with the link 0, or to be disengaged therefrom. Said hook has a straight shank, 0, whose rear end, (I, is enlarged, as shown. A spring-buffer, D, is arranged to slide in the rear end of the draw-head A, and acts on the hook B, pushing it forward, so that its head projects under the shoulder 11, and is thus prevented from rising or becoming accidentally disengaged from the link. The book has pivot-pinse projecting laterally from its rear end, 01, and entering lengthwise slots in the sides of the Application filed March 30, 1880. (No model.)
draw-head. Other pins,f, are located in front of such pivot-pins e to serve as stops to prevent the hook being raised too high, which they do by coming in contact with the top of the draw-head. The means employed for drawing back and raising the hook B are the crank E and chain F. The crank is arranged horizontally and transversely in hearings on the car G, and projects laterally far enough to allow it to be operated to uncouple cars without requiring the brakeinan or other person to enter the space between the cars. The chain F connects the crank with the head of the book, so that upon rotating the crank the hook will be drawn back until its head is free of the shoulder b of the draw-head A, when it will be raised into the diagonal position shown in Fig. 1, and will be thus supported until a link attached to another car enters the draw-head, and, striking on the part 01. of the hook, simultaneously depresses and forces back the hook, so that it will resume the horizontal position indicated in full lines, Fig. 1, and completes the coupling. The coupling is thus effected automatically.
What I claim is- In a car-coupling, the combination, with the draw-head having lateral and vertical slots, and the spring-buffer, of the hook B, having lateral pivot and stop pins, as shown and described, for the purpose specified.
GEORGE WILLIAM CURTIS.
