US Patent 7707941: Cartridge assembly for multiple projectiles

US 7707941  ·  granted 2010-05-04

Abstract

A cartridge assembly (10) for firearms or weapons, said cartridge assembly including a support body (11) having a central longitudinal channel (16) housing a plurality of projectiles (20, 22, 24) in end-to-end orientation and having a plurality of circumferential chambers (14), wherein each chamber houses (14a, 14b, 14c) at least one propellant charge (12a, 12b, 12c) and is located adjacent to a respective projectile; fluid communication means (18) included in the support body for communicating the products of a gaseous expansion of said propellant from a respective chamber (14) into said central longitudinal channel (16); whereby, upon initiation of a selected propellant charge (12a, 12b, 12c), the communicated products of gaseous expansion from a circumferential chamber force or eject a respective projectile (20, 22, 24) from the cartridge assembly (10). The propellant charges may comprise a volume of propellant material encased in a bag with an igniter.

Abstract

A cartridge assembly (10) for firearms or weapons, said cartridge assembly including a support body (11) having a central longitudinal channel (16) housing a plurality of projectiles (20, 22, 24) in end-to-end orientation and having a plurality of circumferential chambers (14), wherein each chamber houses (14a, 14b, 14c) at least one propellant charge (12a, 12b, 12c) and is located adjacent to a respective projectile; fluid communication means (18) included in the support body for communicating the products of a gaseous expansion of said propellant from a respective chamber (14) into said central longitudinal channel (16); whereby, upon initiation of a selected propellant charge (12a, 12b, 12c), the communicated products of gaseous expansion from a circumferential chamber force or eject a respective projectile (20, 22, 24) from the cartridge assembly (10). The propellant charges may comprise a volume of propellant material encased in a bag with an igniter.

Claim 1

A cartridge assembly including: a support body having a central longitudinal channel housing a plurality of projectiles in end-to-end orientation and having aplurality of chambers arranged around the central longitudinal channel, wherein each chamber houses several propellant charges and is located adjacent to a respective projectile; a plurality of sub-chambers formed in each chamber for accommodating arespective propellant charge of said several propellant charges, each propellant charge can be individually initiated and is associated with an initiator for the individual initiation of the propellant charge; an aperture included in the support bodyfor communicating the products of a gaseous expansion of said propellant from a respective sub-chamber into said central longitudinal channel; whereby, upon initiation of a selected propellant charge, the communicated products of gaseous expansion froma chamber force or eject a respective projectile from the cartridge assembly.
