Abstract
Abstract Incendiary or flame projectile for use with conventional igniter-tracer sems and capable of being propelled over distances up to about 600 yards to ignite hard-to-ignite combustible materials such as wood or canvas, the projectile being operable and efficient at atmospheric pressures and containing a flame-producing composition similar to gas generator propellants of double-base or ammonium perchlorate formulations.

Claim 5
Dependent Claim
74 words
The incendiary projectile described in claim 1 wherein said projectile includes a polyethylene container and said flame-producing composition is fixedly adhered to said container by means of a plurality of spaced transverse grooves disposed around periphery of said container and a corresponding number of spaced grooves in said flame-producing composition aligned with said container grooves, and a sealant material disposed within all of said grooves for additionally securing said flame-producing composition to said container.
Claim 6
Dependent Claim

Claim 8
Dependent Claim
14 words
The incendiary projectile described in claim 4 wherein said sealant is an epoxy resin.
Claim 9
Dependent Claim
52 words
The incendiary projectile of claim 5 wherein a special effects component within said container is axially forwardly said flame-producing composition and of lesser diameter than said flame-producing composition while in communicating relation thereto, said special effects component comprising an ignitable material selected from the group consisting of flash-producing compositions and flame-producing compositions.
Claim 10
Dependent Claim
52 words
The incendiary projectile of claim 6 wherein a special effects component within said container is axially forwardly said flame-producing composition and of lesser diameter than said flame-producing composition while in communicating relation thereto, said special effects component comprising an ignitable material selected from the group consisting of flash-producing compositions and flame-producing compositions.
