Color-disseminating projectile for training cartridge

Claim 1

A color dissimainting projectile for a training cartridge, comprising: a generally cylindrical base member having a prism-shaped axial recess of non-circular cross-section, closed at the rear end and open at the front end; a prism-shaped heavy piston of similar non-circular cross-section slidably disposed in said recess; a cup-shaped ogive member of frangible material, closed at one end and open at the other end, having its open end attached to the open end of said base member to form a cavity therebetween, said ogive member having an annular interior groove forming an annular weak region therein; spring means resiliently interposed between said ogive member and the front end of said piston, for preventing forward movement of said piston prior to impact; and a mass of finely-divided color-producing material substantially filling said cavity; whereby, on target impact, said piston moves forward by inertia, engages said ogive member, breaks said weak region, and disseminates said material into the air, thus producing an easily-visible aerosol color signal in the region of impact.
