The pivoted catch is provided with a top of the draw-head to enable the operation horizontal top portion or plate 5, and the pivot of uncoupling to be performed at that point,

It will also be apparent that the car-coupling is automatic and that the catch 4 and the link-engaging bar '7 may be operated from the top and sides of a car.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificii'lg any of the advantages of this invention.

\Vhat I claim is- 1.. In a car-coupling, the combination of a draw-head provided at its bottom with a fixed catch, a pivoted catch mounted on the drawhead, depending from the top thereof and located above the fixed catch, a link, and a vertically-movable bar mounted 011 the drawhead in rear of the catches, engaging the upper face of the link and connected with and operated by the pivoted catch, substantially as described.

2. In a car-coupling, the combination of a draw-head provided at its bottom with a fixed catch, a pivoted catch depending from the top of the draw-head and located at the top thereof above the fixed catch, and the vertically-disposed link-engaging bar located in rear of the catches and capable of vertical movement independent of the pivoted catch, and provided with a head arranged to be engaged by the pivoted catch, whereby the bar is moved vertically when the pivoted catch is swung upward, substantially as described.

3. In a car-coupling, the combination of a draw-head, a fixed catch arranged at the bot tom of the draw-head, a pivoted catch depending from the top of the draw-head and having a top or plate located above the drawhead, and the vertically-movable link-engaging bar located in the rear of the catches and provided with a pair of forwardly-projecting lugs to engage a link, and having a head supported by the pivoted catch, substantially as and for the purpose described.

4. In a car-coupling, the combination of a draw-head provided at its bottom with a fixed catch, a pivoted catch depending from the top of the draw-head and located above the fixed catch, a car, a transverse rock-shaft journaled on the car and provided at its terminals with handles, and having a centrallyarranged arm and a pair of arms located at opposite sides of the centrally-arranged arm, curved links connecting the pair of arms with the pivoted catch, and connections between the centrally-arranged arm and the top of the car, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
