DESCRIPTION. It consists of a spring loaded striker bolt at the top of which is a grooved pressure head. The bolt is held against the spring by a small glass rod, 0.05 inch in dia-meter, which passes through a hole in the bolt and by a safety device. This safety devi-ce consists of a small pair of tongs, the turned-in ends of which fit into another housing in the bolt and are retained in position by the small spring cramp. In the base of this ig-niter is a percussion cap and the short No. 8 detonator. The igniter and detonator as-sembly are fitted to the H.E. by the thin metal cramp. (See fig. 266.)

OPERATION. In operation it is assumed that the safety tongs are removed by withdraw-ing the clamp. Pressure or a blow on the pressure head will then shatter the glass rod and allow the spring to drive the striker on to the percussion cap.

EMPLOYMENT. Designed to be used as a push igniter for improvised mines, etc., or as an impact igniter for H.E. charges when used in an assault.
