ABSTRACT:
A hand-held electric caulking gun wherein a caulking-driving piston is forced through the caulk-retaining receptacle of the gun in a manner to force caulking from the gun with considerable force and at a continuous easy-to-control flow. The gun includes a spring type clutch linkage between the motor and piston that operates to yieldably disengage the drive source from the piston should the reacting force against the caulk driving end of the piston exceed a predetermined value and a releasing device for allowing the piston to be disengaged of its drive linkage for allowing manual movement of the piston in either direction through the gun.
