22. Weissmann Pressure and Impact Fuze (Weissman Druck- und Schlagzünder)

a. Description. The Weissmann pressure and impact fuze (fig. 25) is an instantaneous, mechanical type. The spring-loaded striker with a circular, metal pressure head is held in a cocked position by a glass rod. This glass rod passes through the striker shaft at right angles to, and between the safety-pin holes. The safety pin is shaped like a pair of tongs and is held in place by a spring clip. The percussion-cap-and-detonator assembly is inserted into the base of the fuze. A metal clamp holds the fuze to the main charge. Without the metal clamp, the fuze is 2 3/8 inches high and 1/2 inch in diameter. The pressure head is 1 inch in diameter.

b. Employment. This fuze was designed to be used either as a pressure fuze in improvi-sed mines or as an impact fuze with prepared charges in an assault on a fortified posi-tion.

c. Functioning. After the safety pin has been removed, impact or pressure on the pres-sure head breaks the glass rod, releasing the striker against the percussion cap, firing the detonator and the main charge.

d. Installing and Arming.

(1)

Insert the percussion-cap-and-detonator assembly in the bottom of the fuze.

(2)

Clamp the fuze to the main charge with the metal clamp.

(3)

Remove the safety pin from the fuze.

e. Neutralizing.

(1)

Inspecht the glass rod to see if it has been cracked or damaged. It if is cracked, do not attempt to neutralize the fuze, but destroy it in place with a prepared charge. If the glass rod is not cracked, carefully insert both ends of a wire or other suitable safety pin in both ends of the safety-pin hole.

(2)

Unclamp the fuze from the main charge.

(3)

Remove the percussion-cap-and-detonator assembly from the fuze.
