Abstract
An explosive hand grenade comprises a hollow spherical shell having a sin opening surrounded by a tubular hub, a tubular housing threaded into the hub and extending into the shell, a barrier plate with an eccentric hole closing the inner end of the housing, booster cup attached to the housing and extending beyond the plate to form a booster charge cavity, a rotatable mandrel in the housing, next to the barrier plate, having an eccentric passage therethrough out of alignment with the barrier plate hole in a first position, a bushing fixed in the housing, next to the mandrel, having a passage aligned with the mandrel passage, a unitary combustible delay cord extending through both passages and preventing rotation of the mandrel, an igniter and a striker therefor for igniting the end of the cord remote from the barrier plate, manually-releasable means for initially preventing rotation of the mandrel and operation of the striker until the grenade is thrown, and a torsion spring for rotating the mandrel, after the cord has burned to the junction of the two passages, from the first position to a second position aligned with the barrier plate hole, to initiate the booster charge.
