Abstract

Abstract An all mechanical fuzing system having an arming system, a stabilization timer, an antidisturbance device, a self-destruct timer, and a trip-line release mechanism. The above elements being interconnected so as to be able to (1) arm a mine, (2) actuate the traps associated with the mine, and (3) destruct the mine a predetermined interval of time after arming.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 214 words
An all mechanical fuzing system comprising a housing, said housing containing therein a slider having a detonator thereon, a centrifugal arming means, said arming means comprising at least one pair of weights, said pair of weights pivotally held in position about a central axis by a biasing means, one weight of said pair of weights having a tab thereon for holding said slider in the inoperative position, a stabilization timer means operably associated with said slider, said stabilization timer means comprising a dashpot device and a plunger assembly, said plunger assembly held in the inoperative position by said slider when said slider is in the inoperative position, an antidisturbance means, said antidisturbance means having a firing pin shaft, a self-destruct timer means operably associated with said antidisturbance means and said slider whereby spinning of said fuzing system about said central axis causes separation of said weights thereby moving said tab out of the slider holding position enabling said slider to move to the operative position wherein said firing pin shaft is positioned operably opposite said detonator and whereby movement of said slider to the operative position releases said plunger assembly and enables said plunger assembly to move into the operative position wherein said plunger assembly penetrates said dashpot device thereby sensitizing said fuzing system.
Claim 2
Dependent Claim 214 words
An all mechanical fuzing system comprising a housing, said housing containing therein a slider having a detonator thereon, a centrifugal arming means, said arming means comprising at least one pair of weights, said pair of weights pivotally held in position about a central axis by a biasing means, one weight of said pair of weights having a tab thereon for holding said slider in the inoperative position, a stabilization timer means operably associated with said slider, said stabilization timer means comprising a dashpot device and a plunger assembly, said plunger assembly held in the inoperative position by said slider when said slider is in the inoperative position, an antidisturbance means, said antidisturbance means having a firing pin shaft, a self-destruct timer means operably associated with said antidisturbance means and said slider whereby spinning of said fuzing system about said central axis causes separation of said weights thereby moving said tab out of the slider holding position enabling said slider to move to the operative position wherein said firing pin shaft is positioned operably opposite said detonator and whereby movement of said slider to the operative position releases said plunger assembly and enables said plunger assembly to move into the operative position wherein said plunger assembly penetrates said dashpot device thereby sensitizing said fuzing system.
Claim 3
Dependent Claim 117 words
An all mechanical fuzing system as defined in claim 1 wherein said antidisturbance means further comprises a stationary magnet fixedly secured to said housing, a rotating magnet fixedly secured to said firing pin shaft, an eccentric antidisturbance weight loosely secured to said firing pin shaft, said rotating magnet being aligned north to north and south to south with said stationary magnet in a magnet repulsion position, said rotating magnet being held in said magnet repulsion position by a tab fixedly mounted on said plunger assembly, whereby movement of said plunger assembly into the operative position moves said tab into position between said rotating magnet and antidisturbance weight thereby releasing said rotating magnet and sensitizing said antidisturbance means.
Claim 4
Dependent Claim 105 words
An all mechanical fuzing system as defined in claim 2 wherein said self-destruct timer means comprises a gas filled chamber, a spring-loaded piston rod within said chamber, a self-destruct leaf spring adjacent one end of said chamber and in operative alignment with said antidisturbance weight, and a puncture diaphragm sealing the other end of said chamber, one end of said piston rod holding said leaf spring in an inoperatIve position, whereby movement of said slider to said operative position causes a pin mounted on said slider to puncture said puncture diaphragm thereby slowly releasing the gas within said chamber and sensitizing said self-destruct timer means.
Claim 5
Dependent Claim 51 words
An all mechanical fuzing system as defined in claim 3 wherein said plunger assembly comprises a spring biased plunger and said dashpot device contains a high-viscosity fluid material therein, said fluid material retarding the penetration of said plunger into said dashpot device when said plunger assembly is in the operative position.
Claim 6
Dependent Claim 20 words
An all mechanical fuzing system as defined in claim 4 wherein said slider is spring biased into the operative position.
Claim 7
Dependent Claim 26 words
An all mechanical fuzing system as defined in claim 1 wherein said housing further contains a trip-line release means operably associated with said stabilization timer means.
