A rotary power hand tool (R) with a rotary chuck (T) is mated to a push-in piston-type dispensing container of caulking (A) via an adapter (10) which mounts on the tool and is secured to the chuck. The adapter has a plunger (102) provided on the end of a non-rotating screw (100). When the tool trigger (S) is actuated, a transmission (18) on the actuator is operated to advance the screw and plunger thus advancing the piston on the dispensing container. In the preferred embodiment a peg (112) 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. |
