Multi chamber nail gun

Abstract

A powered nail gun that has two chambers or supply cartridges to hold nails of different sizes or types wherein each chamber can be selectively rotated into the ready-for use position. A pivot assembly is mounted under the compression chamber of a pneumatically powered nail gun, having a pivot member, a rotatable connecting plate at the lower end of the pivot member, a first supply cartridge connected along one side edge of the connecting plate facing in one direction and a second supply cartridge connected along the opposite side edge of the connecting plate facing in the direction opposite that of the first supply cartridge, the forward end of each supply cartridge having a firing position to receive and position a nail for impact by the drive mechanism of the nail gun. When one of the supply cartridges is rotated to the ready-for-use position, its forwardly located firing position is in registration with the impact end of the drive mechanism. Each supply cartridge includes a spring biased follower to urge the nails in the cartridge forward, moving the nail next in line into the firing position after the one previously in the firing position has been driven into a work piece.
