Abstract: A hand grenade with a projectile body spring urged away from a drop cap having pivotally mounted half shells encompassing the projectile body and a safety bolt normally holding the shells in their encompassing position, is provided with a firing pin containing slide spring urged into engagement with the percussion sensitive primer and held against its spring bias by the safety bolt. After the firing pin strikes the primer, the slide member continues further under its spring bias into engagement with cam jaws for releasing the secure connection between the cap and projectile body.

Abstract: A mechanical delay device provided with a throttle passage between two sealed chambers, with a piston in one chamber to displace a plastically deformable flowable mass from the one chamber to the second chamber. A pin extends through the second chamber to adjust the throttle passage and to surround it with a reset piston movable in the second annular chamber by relative rotation of two housing parts to move the flowable mass back into the first chamber.

Abstract: A non-metallic mine pressure fuse, having a housing comprising upper and lower portions secured together, a leaf spring with its peripheral surface retained between the upper and lower housing portions and its central portion projecting upwardly in the unbiased state, a percussion pin supported for axial displacement relative to the housing and retained at a central aperture provided therefor in the leaf spring so as to penetrate a percussion explosive charge in the lower housing upon flexing of the leaf spring to a downwardly projecting position, a trip member projecting from the upper surface of the housing and arranged for axial displacement relative thereto, and a pressure translating member interposed between the trip member and the leaf spring to cause a downward flexing of the spring upon an external pressure in excess of a predetermined value applied to the trip member, wherein detent means are provided to prevent restoration of the pressure translating member to its initial position prior to the exertion of a pressure of lesser magnitude than the predetermined value.
