Abstract: An improved sabot fragment and gun gas diverter of particular utility in conjunction with a rotatable multiple barrel gun is described, which comprises, a diverter member mounted forward of the barrels for rotation therewith and defining a generally conical, radially outwardly divergent impact surface from which sabot fragments are diverted outwardly upon impact thereon; a plurality of axial bores through and spaced around the diverter member correspond in number to and are respectively coaxial with the rotatable gun barrels; an impact surface is attached to the gun forward of the diverter member for diverting the fragments from the gun in a predetermined direction relative to the gun; a housing around the diverter member defining an internal chamber into which the fragments are diverted from the diverter member may include the impact surface as a forward end wall thereof, and may include an exit port for passage of fired projectiles and discharge ports for discharging diverted sabot fragments.

Abstract: A cartridge chamber housing and a breech block for a cartridge with side-mounted primer, in which the chamber housing has a firing pin and a spring-biased slidable firing pin interrupter which is in firing-prevent position and prevents firing pin actuation except when the breech block is closed and locked, and which is moved to firing-enable position by the closure and locking of the breech block, whereby the firing pin may be actuated after such closure and locking of the breech block. The cartridge is fully chambered and extracted by and as a function of closure and opening of the breech block.
