DESCRIPTION. The main difference between the S-Mine 44 and the S-Mine 35 are in the use of a push-pull type igniter (S.Mi.Z. 44) and the fact that the mine detonates at a pre-determined height, of approximately 36 inches. For recognition purpose it should be noted that the igniter tube is not located in the center of the mine as it is in the S-Mine 35.

The mine consists of an outer steel case container an inner canister. (See fig. 245.) The canister holds the TNT explosive charge which is surrounded by small shot. In the cover plate there are three screw-covered openings; one for pouring the charge, one for the igniter socket beneath which is the propellant (3 gm of burning gun-powder), and a 4 1/2 second delay pellet all in a celluloid case, and a third opening for a pull igniter and deto-nator. The pull igniter is at the base of the center tube and immediately above it is a flash cap for initiating the detonator. The pull igniter contains a spring-loaded striker, the sleeve of which is held beneath the internal shoulders of the igniter case by two balls which are prevented from moving inward by a pin in the base of the igniter. The pin is attached to about 2 feet 10 inches wire to the base of the outer case.

OPERATION. After the detonator has been inserted and the igniter fitted and armed by with-drawal of a safety pin, the igniter can be operated either by pressure or pull on the trip wires. Operation of the igniter initiates the 4 1/2-second delay pellet. After the delay the propellant is fired, throwing the mine upwards. When the coiled wire is fully extended it pulls the pin from the igniter, thus allowing the retaining balls to move inward and re-lease the striker upwards to fire the cap, detonator, and bursting charge.

EMPLOYMENT. The mine is employed in the same manner as the S-Mine 35 for pressure or tension operation.
