Illustrative embodiments of the invention provide a visually inspectable primer and detonating charge cannister for a fuse for hand grenades and other munitions and explosives. The delay charge, moreover, is effectively symmetrical to permit reliable fuze operation in spite of incorrect assembly. The primer is sealed in its bore in the fuse body by means of a crimped ring which leaves the primer exposed to visual inspection to insure its correct orientation within the fuse. The delay charge is made symmetrical by removing the initiator charge from its usual location in the delay charge housing and placing the initiator in a detonating charge cannister. By placing the initiator next to the crimped end of a detonating charge cannister, the detonating charge also becomes not only amenable to visual inspection, but also less subject to deterioration through moisture attack. |
