EMPLOYMENT: Czech nose fuze used in German 4.7-cm ammunition (See. fig. 573.)

DATA:

Overall length: 2.438 inches.

Maximum diameter: 1.625 inches.

Threaded length: 0.625 inch.

Number of threads: 10 RH.

CONSRTUCTION: The body has a closing disk in the nose and threads on the base to engage the projectile. Beneath the closing disk is a wooden hammer which bears against the striker.

The striker, creep spring, primer holder, and centrifugal segments are all contained in a single inner housing which screws into the base of the fuze body and is secured by a locking nut.

The centrifugal segments are interposed between the striker and primer housing. A light creep spring surrounds the striker and bears against a lip one the primer housing.

ACTION: Centrifugal force throws the centrifugal segments outward freeing both the striker and the primer housing which are then separeted only by the creep spring.

Upon impact, the hammer forces the striker back to meet the primer which has been thrown forward by inertia. The resulting flash passes through the central channel into the detonator.
