  • Retainer for grenade body loading assemblies for demolition of unexploded ordance
    Patent number: 4993324
    Abstract: A retainer for retaining a body loading assembly of a U.S. Army M42 or M46 eneral purpose grenade in firm intimate contact with at least one detonating cord, or an electric or non-electric blasting cap for use in explosive demolition of unexploded ordnance designated for disposal. The inner diameter of the retainer is nominally the same as the outer diameter of the body loading assembly with retention achieved by friction after insertion of a grenade body into the retainer. Holes in the wall of the retainer allow insertion and retention of one or two segments of detonating cord, or of an electric or non-electric blasting cap against the primer lead cup of the grenade body loading assembly for reliable initiation.
