Abstract

996,734. Projectile fuzes. BREVETS AERO - MECANIQUES S.A. Feb. 19, 1964 [March 5, 1963], No. 6951/64. Heading F3A. A direct action percussion fuze for a rotating projectile has retractable means 9 for locking a firing pin 1 by acting against a shoulder 1b on the firing pin 1 which is weakened locally at 1c. The fuze comprises the firing pin 1 with a shoulder 1a butting against a split ring 4 surrounded by a spiral strip 5 and a split sleeve 6 which spread open to free the firing pin 1 with some delay in time in response to centrifugal forces as in Specification 833,902, the shoulder 1b and retractable means 9 consisting of four cylindrical pins mounted in radial housings behind the shoulder 1b and being urged towards the fuze axis by an expandable annular spring clip 10. The firing pin 1 is weakened by means of a transverse drilling lc. On accidental crushing of the fuze nose the shoulder 1b on the firing pin 1 strikes the pins 9 and the firing pin 1 becomes deformed around the drilling 1c to jam in the portion 7a of a guide bore 7.
