Telescopic nozzle for an air gun with safe pressure release

A nozzle being of the type attachable to a source of compressed gas and being the type having a plurality of extensible telescoping sections comprising:

• an inner sleeve and an outer sleeve, said outer sleeve slidably telescoping onto said inner sleeve;
• said inner sleeve having an entrance end joined joinable to said source;
• said outer sleeve having an exit end joined to an entrance end of said plurality of telescoping sections;
• said inner sleeve having an aperture and said outer sleeve having an aperture providing that a passageway is open when said aperture in said inner sleeve and said aperture in said outer sleeve are aligned and said passageway is completely closed when said apertures are misaligned;
• a plug secured in said inner sleeve;
• a bore extending from an entrance end of said plug to an exit end of said plug whereby said gas is enabled to pass through said plug;
• said plug constructed in operable combination with said inner sleeve to form a cavity between an inner surface of said inner sleeve and an outer surface of said plug;
• at least one planet bore leading from said exit end of said plug to said cavity;
• said cavity secured in said inner sleeve at a location whereby gas is enabled to pass from said exit end of said anchor section, through said at least one bore through said cavity and out through said passageway when said passageway is open
• a spring mounted on said outer sleeve;
• said spring having one end secured to said outer sleeve and an other end secured to said inner sleeve;
• said spring biased both axially and rotationally to return to a position where the aperture in the inner sleeve is aligned with said aperture in said aperture in said inner sleeve providing that, when a mechanic holds said nozzle with said passageway completely closed, maximum velocity of gas through said nozzle is achieved and when he releases said nozzle, said passageway opens whereby pressure in the nozzle is prevented from increasing to a level causing said telescoping nozzle to extend;
• a collar dimensioned to slide onto and around said outer sleeve;
• said collar having a slot and tightening screw operably arranged to select tightness of said collar on said outer sleeve.
