CONSTRUCTION. The outer case of the flare is an aluminum cylinder with base. A push-on type lid is held in place over the top of the case by a strip of adhesive tape. Inside the flare, at the base is a locating piece with a raised section at the center over which slides a perforated aluminum cylinder. On the outside of this cylinder is wound a length of quickmatch, the upper free end of which projects into the top of the cylinder. Between the perforated cylinder and the outer case is the smoke filling. The perforated cylinder is positioned at the upper end by a loose-fitting disc over which sits a metal ring. (See figs. 81 and 82.) The igniter is located in an inverted cap, held in place by a locknut. The cap has four smoke escapes covered by cellophane.

The orange 80 differs from the 160 in that the aluminum locating discs and ring of the 160 have been replaced by similarily shaped cardboard pieces. The inverted cap to which the igniter is secured contains six holes instead of four. The outer cap is held by a bayo-net joint and adhevise tape.

OPERATION. Both igniters function on the same principle. The igniter container hold a compressed powder pellet (in the orange 160) or a rubber tube containing a length of safety fuse. Above the powder pellet or safety fuse is a friction cap through which pas-ses the friction wire. The friction wire is coiled at its lower end to resist the pull. A pull-chain is attached to the ring at the top of the friction wire. When this is pulled, the fric-tion wire passes through and ignites the cap which in turn ignites the powder pellet, or safety fuse.
