ABSTRACT:
A cordless electric powered caulking gun for pressurizing a tube of highly viscous substance includes a ball drive rod having a helical thread and a keyway, an electric motor and gear reducer coupled to a spur gear keyed to the ball drive rod, a cylindrical ball retainer having a plurality of pockets located on a helical locus aligned with the helical thread, a plurality of balls with one ball in each pocket of the retainer, a ball drive nut telescoped over and selectively axially moveable between a first and second position with respect to the ball retainer, and a trigger coupled to the ball drive nut via a spring to urge the nut from the first position to the second position when the trigger is actuated. The trigger further has a bearing surface and axial contact with the ball drive nut to force the nut to the first position when the trigger is released to a deactuated position. The ball drive nut holds the balls in engagement with the rod when the nut is in the second position and lightly holds the balls in engagement with the rod when the nut is in the first position, but permits the disengagement of the balls with the rod when the rod is moved manually.
