ABSTRACT:
This device is for an air operated safety latch designed to hold a folding pole trailer in its stationary or folded position when traveling. The device is comprised of a housing which supports jaw members which can move from an open to a closed position when a pole or other longitudinal member is placed between the jaw members, springs attached to each jaw member, a pivot arm attached to a latch block which locks the jaw members in place when the jaw members are closed, a spring to pull down on the pivot arm and to assist the locking mechanism, and a two-way air cylinder which can serve as a back-up to the locking system and which can be used to unlock and open the jaw members.
