Abstract
245,726. Brandt, E. W. Jan. 12, 1925, [Convention date]. Projectiles; gun cartridges.-Relates to projectiles, for smooth - bore mortars, of the kind having a tapered rear part, for example as described in Specification 245,711, and a winged perforated tailpiece adapted to contain a propellent cartridge. According to the invention, the tail-piece 6 is relatively short and has a plurality of fins 12, the volumes of the spaces between which are proportional to the total cross-section of the perforations 7 opening out into the respective spaces. The fins may be cast integral with the tail-piece, or may be riveted, soldered, or welded thereto. Two adjacent fins may be made in one, as shown in Fig. 3. The outer edges of the fins may be flanged along their whole length or along a part 14 to strengthen them and increase their guiding action; the parts not flanged are rounded. off. These flanges serve also to hold additional propellent charges for longrange firing. The inside of the tail-piece is grooved at 10, so that the wall of the cartridge 9 is expanded into and gripped by that groove when the shot is fired, ensuring the cartridge being carried away with the projectile. The cartridge contains a cardboard liner 11 with an intermediate waterproof coating.
