ABSTRACT:
An improved stored energy impact fuze wherein a spring loaded firing pin is normally restrained in the spring loaded position by a holding mechanism which includes a ball detent positioned in a slot on the firing pin and held in place by a hinged plate. Upon impact, the hinged plate is driven forward allowing the ball detent to move away from the slot on the firing pin, thereby releasing the firing pin. The hinged plate is held in position by a holding pin which lies between the plate and a rotor carrying a detonator. The fuze is activated by rotating the rotor so as to place the detonator in line with the firing pin. In its activated position, a hole in the rotor is also lined up with the holding pin. Upon impact, the holding pin is allowed to move into the hole in the rotor, thereby releasing the hinged plate, and in turn releasing the ball detent holding the firing pin.
