Abstract
A rotary power hand tool with a rotary chuck is mated to a push-in piston-type dispensing container of caulking via an adapter which mounts on the tool and is secured to the chuck. The adapter has a plunger provided on the end of a non-rotating screw. When the tool trigger is actuated, a transmission on the actuator is operated to advance the screw and plunger thus advancing the piston of the dispensing container. In the preferred embodiment a peg secured to the drive screw and protruding out of the adapter doubles as a way of preventing the drive screw from rotating and as a way to indicate the relative amount of contents remaining to be dispensed until the container is effectively empty.
