EMPLOYMENT: Mechanical time and/or impact nose fuze used in German 8.8-cm and 10.5-cm H.E. antiaircraft shells. (See fig. 596.)

DATA:

Over-all length: 4.375 inches.

Maximum diameter: 2.375 inches.

Threaded length: 0.500 inches.

Number of threads: 4 RH.

CONSTRUCTION: The body construction and clock mechanism are similar to the Zt.Z. S/30 Flg. It differs in that the time can be set up to 60 seconds and it has an impact firing pin. A firing pin rod passes through the hollow center of the fuze. This rod is kept in place by the fact that is diameter is larger than the hollow center hole. The whole dia-meter is enlarged, however, by the action of a gear train which is activated by centrifu-gal force.

The firing pin is also released during flight by a centrifugal arm.

ACTION: The clockwork delay action is the same as that the Zt.Z. S/30 Flg.

When the fuze is set for impact, the firing pin rod is driven through the enlarged hole in the hollow shaft forcing the firing pin into the detonator.
