ABSTRACT:
The locking mechanism of the present invention is comprised of a pawl which is rotatable to a locking position, where it contacts the latch which covers the pintle that carries the trailer drawbar. The pawl has a central cavity which contains a pair of rotatably mounted prongs that normally extend outwardly from the sides of the pawl but which can be placed into the cavity when manually deflected. When the pawl is in its locking position, against the latch, the prongs extend into notches in the side walls of the body of the coupling and thereby prevent the pawl from being lifted off of the latch. A cam, which is rotatably mounted on the bolt which journals the pawl, has paired plates which fit behind the prongs and prevent them from being deflected into the cavity. Thus, before the prongs can be deflected and thereafter the pawl lifted to unlock the latch, the cam must be rotated to a position where its faces are moved away from the prongs.
