Japanese Patent JPS5815631
Kind Code:
B2
Abstract:
A hand held, hand operated tool is disclosed which has an outer cylindrical body and an inner, spring loaded plunger-piston assembly. The piston may be cocked and then held by a trigger mechanism in a forward position next to a nozzle or tip member. When the trigger is released, the piston flies back rearwardly drawing a sharp impulse of air into the cylindrical body through the nozzle member. A cocking shaft affixed to the plunger extends rearwardly out of the body and may be pushed forwardly into the body for each desired cocking stroke. A sheath for the cocking shaft is also carried by the body and is movable axially thereon. The rearward end of the sheath is closed and is engaged by the hand of the operator to push the cocking shaft into the cylindrical body of the implement. The cocking sheath is then returned by a second, light spring to its fully extended position, while the cocking shaft is held forwardly by the trigger mechanism. The cocking sheath provides both a handle and a protection covering for the cocking shaft.
