Abstract
A coupler to connect rail-highway vehicles end to end including a female member at the end of one vehicle into which extends a sensing member, a male member at the end of an adjacent vehicle adapted to enter the female member, the male member including a vertical hole therethrough, and linkage connecting the sensing member with a vertical locking pin so that as the male member approaches its fully inserted position in the female member it contacts the sensing member and actuates the linkage to automatically urge the vertical locking pin through the vertical hole, the assembly being such that the weight of the vertical locking pin cannot retract from the vertical hole and cause an unlocking action to occur. In the uncoupling action, the vertical locking pin is first retracted and upon full withdrawal of the male member, the sensing member re-enters the female member, the entire assembly then being reset for automatic coupling when necessary.
