  • Igniter bag
    Patent number: 5063848
    Abstract: An igniter bag for a cannon cartridge is disclosed which comprises a generally toroidal annular bag of combustible fabric such as cotton or rayon containing an ignition powder. The bag has a plurality of radial seams separating the bag and the powder contained therein into separate adjacent compartments within the bag so that movement of the powder within the bag is substantially restricted. This construction prevents side to side shifting of the ignition powder during storage, handling and loading of the cartridge.
