ABSTRACT:
A caulking device uses a long flexible tube (40) to connect a belt-worn cartridge housing (50), which accepts standard caulking cartridges, to a hand-held gun (20). The housing contains an electric motor and drive mechanism to force a piston into the cartridge. Caulking is pushed from the cartridge into the flexible tube, through the tube to the gun. The gun contains a trigger-actuated valve which allows caulking to pass into a disposable nozzle from which it is dispensed to the workpiece. A pressure sensor in the housing activates a switching circuit to maintain pressure in the tube.
