GERMAN PROJECTILES FUZES |
BASE FUZE - M. 35 |
EMPLOYMENT: Base fuze used on German 4.7-cm A.P. ammunition. (See. fig. 606.) |
DATA: |
Over-all length: 2.656 inches. |
Maximum diameter: 1.406 inches. |
Threaded length: 0.688 inch. |
Number of threads: 11 RH. |
CONSTRUCTION: The body is threaded externally at the middle to engage the threads of the projectile. A detonator is screwed into the top of the fuze and a tracer is crimped into a recess at the base. |
A primer housing with a funnel-shaped hole through it and surrounded by a compressed spring is held in place by six steel balls. The collar which retains these balls increases in diameter towards the top. |
ACTION: The primer housing is locked in place by the steel balls until the projectile stri-kes an object. Inertia causes the housing to move forward compressing its spring. The locking balls move forward also and are cammed out into the enlarged portion of the re-taining ring. The primer then impinges upon the striker and the flash passes through the funnel-shaped hole firing the detonator. |
