Abstract
The objectives of these inventions are to provide simple, reliable, and low-cost mechanical means to obtain (1) second impact detonation and (2) substantial safe arming separation from the gun for point detonating fuzes for small caliber spin stabilized shell. The first objective is attained by use of a heavy shield over the firing pin which is removable between the first and second impacts by spin forces; the second objective is attained by a centrifugally driven rotor, containing the out-of-line explosive element, which deforms a ductile material to effect the arming delay.
