<p>The chuck of an electric drill mounts an annular collar which may be fitted to the rotary actuator of a twist top dispenser cartridge for caulking or the like. As the drill is operated, the chuck rotates the collar which turns the rotary actuator thus dispensing the cartridge contents. By preference, the adapter of which the collar is a part incorporates a clutch which permits the user to initiate and terminate dispensing, without releasing the trigger of the electric drill, by manipulating the cartridge relative to the electric drill.</p> |
