Abstract
An explosive-train, arming-rotor type fuze mounted flush with the skin of a eapon wherein the arming rotor is doubly out-of-line in the safe position, and where both linear translation and angular rotation is required to align the explosive train in the armed position. A visual and tactile indicator is provided, the fuze being "safe" when it remains flush, and being able to become "armed" when the fuze protrudes from the skin of the weapon.
Claims17
A safety and arming device for an ordnance fuze comprising:
- a housing receivable within the fuze and longitudinally movable from a first position flush with the top surface of the fuze to a second position protruding above the fuze;
- an arming rotor rotatably supported on the bottom of and longitudinally movable with said housing;
- motive means within said housing to control rotation of said rotor into an armed position only when said rotor is in said second position;
- spring means urging said housing and said arming rotor out of said position to said second position;
- releasable restraining means for maintaining said rotor and said housing in said first position;
- and
- an electro-responsive explosive device positioned in said arming rotor and forming a part of an explosive arming train in the fuze,
- said rotor being normally held in the safe position with said housing being flush with the fuze and said explosive device being axially and rotationally out-of-line with the explosive arming train.

An ordnance fuze having dual out-of-line safe positions comprising:
- a housing adapted to be mounted flush with the surface of the ordnance;
- a recess in the base of said housing;
- an explosive arming train in the base of said housing adjacent said recess;
- a safety and arming device receivable in said housing comprising:
- containment means for a source of power, said means longitudinally movable from a first position flush with the surface of the ordance to a second position protruding above the surface of the ordnance;
- and
- an arming rotor containing a component of said arming train and rotationally positioned adjacent said containment means, said rotor being receivable in said recess and longitudinally movable with said containment means in said housing from a first axial position with said recess to a second axial position and rotatable only in said second axial position to complete the arming train;
- spring means for urging said containment means and said arming rotor out of said first axial position;
- releasable restraining means for maintaining said containment means and said rotor in said first axial position;
- and
- means in the containment means for rotating said arming rotor in said second axial position to align said arming train in the armed position.
