DESCRIPTION. The striker bolt is apparently constructed in two parts, the inner compo-nent supporting at its top end the hollow pressure cap on the top of which is a small me-tal vane. The bolt is contained in a stout casting and is normally retained in that position by a spring when the horizontal safety pin is removed. The base of this igniter is the per-cussion cap and a No. 8 detonator. Above the percussion cap is a safety device consist-ing of a small wing shaped shutter which is pivoted at one end. When the igniter is unar-med this shutter is held over the percussion cap, against the action of small spring, by the vertical safety pin. (See fig. 265.)

OPERATION. Pressure on the pressure cap overcomes the resistance spring and shear pin and forces the striker into the percussion cap. Flame from the percussion cap ignites the detonator.

EMPLOYMENT. Designed for use as a push or impact igniter on improvised mines.
