Journal . hrough the graze pellet to the base of the fuze, whereit is closed by the safety shutter (G). Into the base of the fuzeis screwed the adaptor (H), carrying the Gaine (K). The Gaine consists of a metal cylinder bored out from bothends, the top cavity containing a pellet of delay compositionand the bottom cavity forming a magazine, the two cavities beingconnected by a flash hole. One object of the Gaine is to delaythe bursting of the shell, but it also effects more reliable andmore complete detonation. Action.—On discharge from the gun the weight (D) sets backcompressing the spring behind it and withdrawing the pin ;the top of this pin falls to one side and so prevents it from returningto its original position ; the centrifugal bolt (C), thus freed,slides outwards freemg the graze pellet (B), which, however, isprevented by the creep spring from any tendency to moveforward on to the firing pin. At the same time the safety shutter 154 ARTILLERY FROM THE SCIENTIFIC AND DELAY FUZE. S. ENGINEERING POINT OF VIEW. 155 (G), under the action of centrifugal force, flies outwards, andis prevented from returning by the ball-headed pin falling toone side (thus acting like a pawl). On impact the graze pelletflies forward compressing the creep spring and driving the igni-tion cap on to the firing pin, thus causing a flash to pass to thegaine, which delays the final detonation sufficiently to allowthe shell to bury itself and so have a good crater effect.
