Abstract
This invention pertains to a disposable tubular cartridge and apparatus for expelling the contents from said cartridge. This novel apparatus does not employ the conventional U-shaped receiver into which the cartridge is placed but provides a self-contained handle to which the rear of the cartridge is attached. This handle is usually a pistol grip in shape. Rather than a rigid ratchet expelling shaft and an exterior twist handle the present apparatus provides a curved trackway and an expelling drive train, a portion of which is flexible in one direction. The drive train has a ratchet engaged and moved by a lever handle and a pivoted pawl leaf. A stop finger is carried by this lever handle and is disposed to prevent counterflow movement of the drive train. Several methods are shown for attaching the tubular container and the drive train is also shown employing several alternate constructions. In each embodiment the lever handle and associated members are swung to a disengaged condition whereat and whereby the piston disc carried by a rigid shank portion may be manipulated for moving the drive train to a retracted position and condition.
