Use: A.P.-H.E. projectiles for 37-mm tank and antitank gun.

Description:

Over-all length: No data.

Maximum diameter: 1 7/32 inches.

Threaded length: 1/2 inch.

Number of threads: 8, right-hand.

Construction: The fuze is made of one piece of black steel which houses the base pla-te, striker, arming sleeve, creep spring and firing train. The after end of the striker fits into a recess in the base plate and has an enlarged shoulder to engage the arming slee-ve. A creep spring is housed in the arming sleeve resting between the primer housing and an inner shoulder of the arming sleeve. The striker is held from the primer by a shear wire which passes through the arming sleeve and the striker.

Operation: On set-back the shear wire is broken. The arming sleeve moves back and is wedged on the after end of the striker, exposing the forward end of the striker beyond the forward end of the arming sleeve. On impact the striker and arming sleeve, which now act as one piece, move down against the creep spring with the striker, piercing the primer.
