IIIPROVZED COUPLING.

The Schedule referred to'in these Letters Patent and making part of the name.

Be it known that I, A. B. THOMPSON, of Owego, county of Tioga, and State of New York, have invented a new and improved Oar-Coupling; and I do'hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingdrawings makingpart of this specification, and to the letters of refere nce marked thereon. Y v

My invention consists in constructing a car-coupling,

. asshown, the hody'or principal part of which is made of cast-iron, nearly of the usual form, externally, and 1 common links are also used, but, instead of employing a pin, the link is caught and held by a peculiar-shaped hook. The hook is operated by alever, and theattendant need not go between the cars to couple, detach, or, in coupling, to raise and lower the link to couple cars varying in height.

1 To enable others'skilled-in the art, or that to which back from the link to'the pin 4?, turns at a right angle, and descends through an opening in the piece A, and also through a hole in the lever 0, which is attached to the bottom of the draw-head.

The lever o is pivoted at one end to a lug or ear cast on one side of the draw-head; the lever then crosses beneath and extends sufficiently for an attendant todraw-head A, and the hook, after going' operate it without necessarily going between the cars to do so.

On the lever'is a ro1ler,-c, Figures 1 and 4, which moves ina curved path on the under side of the drawhead, and the lever is held firmly up by means of a spiral spring beneath it, and surrounding the part of the hook D, which descends through the lever, and a sufficient distance below it, to receive the spring.

In uncoupling, the lever is moved forward, which lifts-thejhook, and. the link may be withdrawn, but,

it is desired to back a car into a switch, the lever is thrown forward, and remains in that position by means of the friction-wheel sinking into a depression in its path, where it isheld by the spiral spring.

Cars to be left at a distance may be uncoupled without danger,-by grasping the lever as a train is passing at considerable speed.

In'coupling, the lever is moved back, which depresses the hook; the hook forces down the inner end-of the link, and the mouth of the draw-head is constructed to act as a fulcrumto elevate the outerend of the link to the proper height to enter the draw-head of the car coming up. a

. What I claim as my invention, and desire to secure by Letters Patent, is-- The combination of the hook D and the lever O, with its spring and roller 0, arranged to operate in the draw-head A, substantially as and for the purpose herein specified.
