ABSTRACT:
A jaw assembly for a fifth wheel hitch includes a support plate, a jaw bolt mounted for relative sliding movement on the support plate between open and closed positions and a trigger for positively holding the jaw bolt in the open position. A spring is connected between the jaw bolt and trigger in such a way as to perform the dual function of biasing the jaw bolt toward the closed position and biasing the trigger into engagement with the jaw bolt so as to hold the jaw bolt open. When the trigger is engaged by a trailer king pin that is to be held in the jaw assembly, the jaw bolt is released and closes under action of the biasing spring.
