Strand ignition for propellant of shell-coated projectile

In an improved cartridge having a shell case housing a propellant and having an ignition device to activate the propellant, an improvement in said ignition device comprising provision of strands of ignitable material, said strands being adjacent, a surface of said propellant;

• a one piece strand holder for said strands, said one piece strand holder having a body with integral forward and aft portions said body being hollow and cylindrical, and having a platform being flat and fitted within said body, and further having a combustion chamber adjacent to said platform in near relationship to the aft portion of said body, a primer head for said body, and said combustion chamber also housing an igniter booster charge;
• igniter means communicating with said combustion chamber for the ignition of said booster charge;
• and a plurality of conduits and channels extending longitudinally along said body of said strand holder in communication with said combustion chamber, said conduits and channels receiving said strands, said conduits communicate between said combustion chamber and said channels holding said ignition strands whereby the ignition of said booster charge in said combustion chamber by the igniter means in sequence will ignite said strands which will act to ignite said propellant.
