4 a f .Mn 5 Lw www J @.z. m 7 S m J a on the exterior thereof. The rock-shaft is journaled in suitable bearings of a car, preferably on the dead wood thereof, and it terminates in crank-handles located at opposite sides of the car. lt is provided, intermediate of its ends adjacent to the

arms

18 and 20, with

lugs

24 and 25, preferably formed by pins or the like proj ecting from the rock-shaft. The lug 24 is located in a bifurcation 26, of the arm 18, at the bottom thereof, and is arranged to engage the same at that poi-ut, whereby, when the handles of the rock-shaft are swung upward, the lug 24 will be carried into engagement with the bottom of the lever or arm 18, to lift the coupling pin. The lugs 25 are arranged in bifurcations 27, of the arms 20, at the tops thereof, whereby when the handles of the rock-shaft are swung down- .ward the lugs will engage the arms 2O and,

through the medium of the bail 2l, force the combined pin-support and link-guider downward against the action of the spiral spring 13, to tilt the link for guiding the same. By this construction the arms of the rock-shaft are operated independently, and when the pin is lifted the pin-support and link-guider is not affected by such movement of the rock-shaft; and on the other hand, when the arms 20 are swung downward, the rock-shaft does not affect the arm to which the coupling pin is attachcd.

Any suitable means may be employed for operating the rock-shaft from the top of the car, and for preventing the coupling pin from being entirely withdrawn from the draw-head.

It will be seen that the car coupling is simple and comparatively inexpensive in construction, that it is positive and reliable in operation, that it is capable of coupling automatically, and that it may be readily uncoupled from the top and sides of a car. It will also be seen that car coupliugis capable of enabling a link to be readily .guided into the mouth of a draw-head without going between cars.

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

1. In a car coupling, the combination of a draw-head, an approximately L-shaped pinsupport and link-guider mounted for vertical 53eme movement in the draw-head and arranged to swing rearward, and a spring connected with the pin-support and link-guider for normally throwing it forward and holdingr it upward, substantially as described.

2. In a car coupling, the combination of a draw-head having a coupling-pin perforation and provided with a link-opening and having a raised portion on the bottom thereof forming a fulcrum, said draw-head being provided inits bottom with an opening and having in its upper and rear walls an approximately L-shaped groove, an inverted L-shaped pinsupport and link-guider arranged in the draw head and having a limited vertical movement and arranged to swing rearward in the said groove, a spring connected with the bottom of the pin-support and link-guider for normally holding the same elevated and thrown forward, and means for depressing the linkguider and pin-support, substantially as described.

3. In a car coupling, the combination of a draw-head provided in its bottom with an opening, a combined pin-support and linkgnider mounted in the draw-head and extending through the opening of the bottom of the same, a spring for holding the piu-support and link-guider elevated, a bail connected with the bottom of the same and having npward-extending sides located on the exterior of the draw-head, and a rock-shaft having arms connected with the sides of the bail, substantially as described.

4. In a car-coupling, the combination of a draw-head, a coupling pin, a pin-support and link-guider, a rock-shaft, a central arm loosely arranged on the rock-shaft and connected with the coupling-pin, the opposite side arms similarly mounted on the rock-shaft and connected with the pin-support and link-guider,

a lug 24 projecting from the shaft and arranged to engage the bottom of the centrallylocated arm, and the lugs 25 arranged on the shaft and adapted to engage the tops of the side-arms, substantially as described.

In testimony that we claim the foregoing as our own we have hereto aitixed our signatures in the presence of two witnesses.
