96. Wooden-Block Mine, Type B

a. Description. The antipersonnel wooden-block mine, type B (fig. 114) is similar to the type A except for the fuze and the pressure lid. The mine is 8 inches long, 2 1/2 inches wide, and 2 1/4 inches high. A charge hole to accommodate the main charge, which is a standard German cylindrical 100-gram (0.22 pound) demolition charge, is bored length-wise about 6 inches through the center of the block. At the other end of the block a fuze hole to accommodate a pull fuze 42 (par. 42) is bored into the charge hole. A woo-den pressure lid pivote about woo-den pegs and rests on the wings of the striker-retain-ing pin of the fuze and has two tongues that protrude through the wings. The open end of the charge hole is closed with a wooden or cork plug.

b. Employment. This mine is laid along paths, trails, road shoulders, approaches to likely fords across rivers and streams, and in antitank mine fields. It may be laid unburied in grass or wooded areas and covered with leaves or other vegetation.

c. Functioning. A pressure of from 6 to 11 pounds on the pressure lid pushes the striker-retaining pin out of the fuze, releasing the spring-loaded striker against the percussion cap and firing the mine.

d. Installing and Arming.

(1)

Push the main charge into the charge hole.

(2)

Close the charge hole with a wooden or cork plug.

(3)

Screw the pull fuze 42, with detonator, into the main charge through the fuze hole. The wings of the striker-retaining pin should be horizontal and below the striker shaft.

(4)

Place the mine in the ground with the fuze end away from the enemy.

(5)

Gently lower the pressure lid so it rests on the wings of the striker-retaining pin of the fuze with the two tongues of the pressure lid protruding through the wings.

e. Neutralizing.

(1)

Check for any neutralize any activating fuzes.

(2)

Raise the pressure lid.

(3)

Unscrew the fuze and detonator from the main charge.

(4)

Remove the detonator from the fuze.

(5)

Remove the wooden or cork plug from the charge hole.

(6)

Tip the mine so the main charge slides out.

Caution: Destroy the mine in place if the striker-retaining pin of the pull fuze 42 is partially withdrawn from the striker shaft.
