ABSTRACT:
A connector to an external air source for a gas-operated gun having a cartridge piercing receiving assembly, including a threaded flange skirt and a hollow cartridge piercing-needle, and an opening to permit extension of an air conduit from the gas-operated gun to a pressurized air source external of the gun comprises a connector body and a nose bushing intregal to one end thereof. An air conduit extends through axially aligned passage bores of the nose bushing and connector body, a seating end of which is internal to the gun and is fixly held in air tight communication over the hollow piercing-needle of a cartridge piercing assembly when the nose bushing, which is threaded at its outer annual periphery, is threadedly engaged with a threaded annular inner wall of the flange skirt. The end of the air conduit external to the gun is fixly held within a connector assembly or plug engaged in a quick change coupler in communication with a pressurized air source external to the gas-operated gun or a quick change coupler of a manifold capable of communication with the external air source. Alternatively, a bored guide cap within a threaded upper outer annular periphery may be provided to threadedly engage the threaded flange skirt and receive, at its inner planar or tapered surface, respectively, a non-threaded spout or a tapered neck and non-threaded spout, respectively, of other embodiments of the connector body which is rearwardly supported by either a thumbscrew or spring coil system.
