COMPONENTS:

The cylindrical mine body consists of a ceramic (pottery) bowl containing the high explosive with a ceramic plate which acts as the spider. These components are separa-ted by a cushion of rubber or similar material and enclosed in asphalt impregnated felt and tarred paper. There is a threaded opening in the top of the mine for assembly of the fuze and a bakelite plug in the bottom, which may be removed for the attachment of an anti-removal device.

Fuze: The fuze, Chemical M5, consists of a cylindrical body attached to a threaded plug. Instead of a metal safety pin, a bakelite cap is screwed on the base of the fuze body. In addition to this cap, there is a safety ring around the fuze body against the flange of the plug which prevents the fuze being screwed into the functioning position in the mine. When mine is armed, a pressure of 275 to 425 pounds pushes down the upper portion of the mine, overcoming the resistance of the synthetic rubber ring. The glass vial is forced down on the striker, bearing on the wooden anvil, and is broken. Mixture of the chemical in the glass vial with the chemical substance surrounding the vial causes a flash which sets off the detonator - booster - main charge.

ARMING:

The safety cap is removed and the fuze screwed into the mine. After mine is laid, the safety ring is removed and the plug is screwed firmly in place. If the safety ring is metal, it should not be left near the mine as it will disclose the location to a mine de-tector.

COLOR AND MARKING:

The mine is painted olive drab and marked in yellow.

REMARKS:

(1) This is a non-metallic mine in order that it cannot be detected by an electro-magnetic mine detector.

(2) An anti-lifting device may be attached by removing the plastic plug in the bot-tom of the mine; however, use of a metal device tends to defeat the purpose of de-signing the mine and fuze with no metal parts.
