Abstract

A diversionary device capable of providing multiple discharges according to a prescribed time schedule. The device preferably assumes the same general form as a prior art stun grenade, including a safety pin that is pulled to arm the device and a spring-biased lever that is released when the device is deployed.

Abstract

A firearm configured to fire only a modified cartridge, while being unable to fire a conventional cartridge. The breech bolt in the inventive device includes an added geometric element that prevents the bolt closing on a conventional cartridge and which will only allow the bolt to close on a modified cartridge.

Abstract

A firearm cartridge with a specially-configured token disc added to its base. The token includes an outer section and a central strike plate. The strike plate includes a strike ball at its center. The presence of the token increases the effective length of the cartridge and thereby prevents the closure of the bolt of a conventional firearm. As a result, the inventive cartridge cannot be fired in a conventional firearm.

Abstract

A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a firing pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and the safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the safety interlock (92) is in the firing position, actuation of the firing pin is enabled.

Abstract

In a multi-burst diversionary device (10) containing a number of pyrotechnic cartridges (22) arranged in a series and a firing arrangement (14), a first of the cartridges is ignited by the firing arrangement, the remaining cartridges are each ignited sequentially by the flash of pressure and heat (hot gasses) produced when a previous cartridge in the series deflagrates. The device has a housing (12) defining a number of compartments (20) in which the cartridges are received. The housing defines flow paths interconnecting the compartments in series and the first compartment with the firing arrangement. Each compartment is also fluidly connected with atmosphere.
