Description
This is a simple fuze consisting of a spring-loaded firing pin and a blank cartridge contained in a cylinder, and a metal clamp to hold the cylinder against the frangible grenade. The clamp has a conical projection which, when the clamp is tightened around the safety pin which passes through the cylinder, also restrains the firing pin.
Functioning
When the grenade is used, the safety pin is removed and the grenade is thrown so as to smash against the target. When the bottle breaks, the tension on the clamp is released and the firing pin, driven by its spring, pushes the cone aside and strikes the primer of the cartridge. The flash from the cartridge ignites the grenade filler. This igniter is used with the napalm grenade.
