Abstract
A one-way gate assembly for a railway trailer hitch includes a pair of movable jaws adapted to assume a first position engaging and holding in place the kingpin of a piggyback trailer. A stiff yoke spring biases a yoke into a first position engaging the jaws to maintain said jaws in the first position. A one-way gate located on the exit side of the jaws is pivotably mounted about a horizontal axis. In one position the gate extends vertically upwardly, blocking exit of a trailer kingpin. A gate spring biases the gate to pivot the gate outwardly and away from said jaws. A first stop engages the base of the gate maintaining the gate in the vertically extending position. The stop is movable longitudinally of said hitch away from the gate to allow the gate to pivot to open position.
