Abstract: Pressure from an external force near the detonating device will collapse or move a triggering rod to thus rock an attached wobbler plate, which rocking will lift a U-shaped clamping claw that will pull a firing pin against the bias of a spring away from a primer to a position where the clamping claw automatically releases the firing pin so that it will move under the bias of the thus tensioned spring to strike and detonate the primer. In the normal position, the clamping claw prevents movement of the firing pin into the primer and the spring is not biased or biased only to a small degree. The wobbler plate has a clamped peripheral weakened sealing portion that breaks when the wobbler plate is subjected to a force above a predetermined magnitude.

Abstract: The projectile has a spring urged firing pin held out of contact with the primer by a first locking ball engaging a release member spring urged into contact with a fluid pressure responsive piston designed to axially move the release member out of engagement with the locking member against the force of the spring upon the occurrence of an external pressure above a predetermined pressure, which pressure reaches the piston through a conduit having therein a normally open valve closed by the tubular wall of the cartridge case. An additional locking ball is held in its position blocking movement of the firing pin by means of a safety member spring urged out of engagement with the ball and held against the force of its spring by the cartridge case.

Abstract: A locking pin extends between the firing pin and primer element of a projectile to prevent their engagement during transport and while within the barrel of the firing device because of the radial abutment of a safety member that will move axially out of engagement only after the projectile has left the barrel of the firing device so that the locking member may move radially outward to arm the device. The safety member may be the radial abutment of the cartridge case tubular wall before firing and the interior surfaces of the firing device barrel during firing, with the locking member preferably being spring urged outwardly. Also, the safety member may be an axially extending pin prevented from rearward movement out of engagement with the locking member by a spacer disc separable upon exit from the barrel or the cartridge bottom piece.
