CHAPTER 5 - FUZES |
Section II. PRESSURE FUZES |
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. |
