ARMY PROJECTILE FUZES |
Type 92 - Small Short-Delay Base Fuze |
Use: A.P. projectiles for 57-mm tank guns. |
Description: |
Over-all length: 2 9/16 inches. |
Maximum diameter: 1 1/4 inches. |
Threaded length: 25/32 inch. |
Number of threads: 9. |
Construction: Threaded onto the base of the fuze body is a metal cap which serves only as a cover for the centrigual detents. Threaded into the forward section is the ex-plosive train carrier. The fuze body houses two centrifugal detents, a striker and a creep spring. The detents, fitting into a circular groove, hold the striker from the primer. |
Operation: With centrifugal force the spring-loaded detents move out, leaving the stri-ker free to move onto the primer on impact. |
