ABSTRACT:
A hand held scellant applicator has a graspable housing and a drive mechanism housed therein. An endless vise is provided with a torque arm slidingly mounted to the housing. A large gear concentrically installed around the vise is held in place by a roller bearing rotating central part, surrounded by balls turning within an outside part mounted on the housing. The vise has inclined planes, and the central part of the bearing has mating planes which ride on the inclined planes of the vise, the rotation of the large gear causing the advance of the vise and the torque arm preventing the rotation of the vise. At pivoting coupling housing disengages the large gear to permit removal of the vise after pushing the scellant out.
