Abstract
An electrically actuated material dispensing gun is disclosed having a body including a handle section and an elongate cartridge support section extending outwardly from the handle section. The cartridge support section includes a cartridge support space and an apertured end wall for receiving a cartridge dispensing nozzle and for dispensing force resisting engagement with a dispensing end of a cartridge positioned in the space. A reciprocatable push rod is carried by the handle section and axially aligned with the space for force transmitting engagement with a piston which in one embodiment is of unique construction. An electric motor is mounted in the handle section. A drive element is rotatively mounted in the handle section and in positive drive, mechanically interconnected, relationship with the rod. The drive element is normally freely rotatable in response to axial motion of the rod. A power train including a multi-stage planetary axially aligned with and connected to the output shaft of the motor. In one embodiment a drive transmission clutch is provided for automatically interconnecting the drive element and the power train and for transmission of driving forces when so in…
