PYROTECHNIC COILED DELAY CORD ASSEMBLY FOR HAND GRENADE FUZE

摘要

An improved hand grenade fuze that has an out-of-line metal sheathed pyrotechnic delay cord helically wound about a mandrel. The delay cord forms the threads of a delay-detonator assembly which cannot be screwed into the fuze head unless the delay cord is present thereby insuring the presence of the delay element.
