An inertial delay mechanism for use in an explosive projectile is provided. The delay mechanism consists of an inertial delay fuse that is precise, doesn't require sensitive primary explosives and doesn't utilize electronic circuitry. The inertial delay fuse includes a free sliding charge element that strikes an anvil located opposite to the sliding charge element. A delay gap is provided between the sliding charge element and the anvil. Upon impact, the sliding charge element slides forward and impacts the anvil, thereby inducing a shock wave in an initiator charge that subsequently results in detonation of main charges. The design is mechanically simple and robust enough to withstand severe g-loading forces that occur during firing and penetration of a projectile.

Inertial delay fuse

A system for firing multiple projectiles in a parallel or diverging manner is provided. The system can comprise tail-end portions of projectiles that add structure to a cartridge, provide for efficient combustion, allow projectiles to transition from a straight configuration in the cartridge to a splayed configuration in a chamber, and ensure complete evacuation of the chamber. The system can include a tail-end portion of a particular projectile with openings that distribute energy from combustion of an ignition charge, facilitating firing of multiple projectiles. A tail-end portion of a projectile can include a ball joint upon which the body portion of the projectile moves causing an angle between the body portion and the tail-end portion. A space can exist in the body portion adjacent to the ball joint to allow off-center shifting of the body portion with respect to the ball joint.

Multiple diverging projectile system

Hard material can be displaced by firing a frangible projectile from a firing device. The projectile has a rear portion that engages the bore of the barrel of the firing device and a front portion that is rotatably journaled to the rear portion. The front portion can be frangible to allow maximum displacement of the hard material. Specifically, the front portion has a core and a plurality of fins extending from the core. At impact, as the fins penetrate the target, the fins separate from the core and spread radially outwardly from the core.

Method and apparatus for displacing material and projectile thereof

An outrigger assembly includes at least one support unit including a first elongated support arm and a second elongated support arm cantilevered and secured to the first support arm. A joist-supporting arm is removably engaged with the front end portion. The assembly further includes an upper support arm cantilevered and secured to the first support arm. A support member having opposed end portions is secured thereto and to the first support member. The upper support arm includes a plurality of L-shaped members mated along an edge thereof. An elongated board is positionable between adjacently disposed rear end portions. The front end portion exerts an upward force against the work area joists while the upper support arm exerts a downward force against a top surface of the work area such that the forces become balanced.
