Abstract

149,114. Darling, R. A. June 19, 1919. Pyrotechnic devices and compositions.-Relates to projectiles which expel a parachute flare during flight, and consists mainly in causing the expulsion by the gases generated by the flare composition instead of by a separate explosive charge. In the form shown, a time fuse 13 vented by holes 30 causes a plunger 32 situated in a partition 28<a> to be driven against a primer 33 for igniting a flare 18. The gases generated by the flare dislodge a covering disk 20 from the mouth of the flare casing 17 and eject the flare and the parachute 24 through the rear end of the shell 10, the base 14, previously retained by pins 15, 16 being simultaneously blown off. The parachute is arranged against a spring 34 in a split casing 23 which, with the help of the spring, opens out and releases the parachute. Several parachutes in tandem fashion may be used. Gas checks 25 are interposed between the open front end of the parachute casing 23 and the base of the flare casing 17. The parachute is connected to the flare by a swivel 26. The flare composition is compressed into a casing 17 which tapers inwardly towards its mouth and is internally screw-threaded to grip the composition firmly. A suitable flare composition contains barium nitrate 16 lbs. 14 oz., magnesium 6 lbs. 10 oz., ammonium perchlorate 2 oz., linseed glue 1 lb. 5 oz., and sodium carbonate 2 oz. To facilitate ignition, a small charge of black powder is provided at the ignition point, or the composition is packed more loosely at that point. In modifications, (1) a ball-bearing is provided for the swivel; (2) the plunger 32 and primer 33 are omitted and the flare ignited directly by the time fuse; and (3) the partition 28a is omitted.
