Filed: 1931-08-12
Abstract: 392,516. Projectiles. BRANDT, E. W., 101, Boulevard Murat, Paris. Aug. 12, 1931, No. 22768. Convention date, Jan. 21. Addition to 374,318. Void [Published under Sect. 91 of the Acts]. [Class 9 (i).] The propelling-impulse braking tube 1, Fig. 1, of a rifle grenade or the like 2, of the kind described in the parent Specification, is filled with a substance 3 which is almost incompressible but is easily displaced or deformed. The substance may be a solid in a finely divided state or, alternatively, a more or less viscous liquid. Suitable substances are rubber, felt, cork, or materials such as wax or resin adapted to melt under the heat generated by the propelling bullet. When liquids are used, the base of the tube 1 is normally closed by a wad 4. For use with jacketed bullets, the substance 3 is replaced by a number of spaced discs 5, Fig. 2, of steel, or the like, which are adapted to be broken in succession by the bullet. Any molten lead from the bullet core is caught and retained by an annular groove between the tube and a ring 6. In a modified construction, a number of cup-shaped members 7, Fig. 3 (not shown), are used alone or in conjunction with the discs 5. The grenade may be used for signalling, incendiary, or smoke-producing purposes, or may be employed as a message carrier. As shown in Fig. 4, the message case 18 is housed within a protective casing 19 and is disposed above a receptacle 15 containing a smoke charge 16. The latter is ignited by a time-fuse composition, which in turn is ignited by the propellant gases issuing through a bore 10. This bore, and a second bore 12 communicating with the outside, are both normally closed by wax plugs 13, 14. A cap 21 is screwed or otherwise secured to the body of the grenade. Fig. 6 illustrates an incendiary projectile comprising a cartridge 29 which contains an incendiary charge 30, an intermediate charge 31, and a time fuse 26. The grenade body is formed by an extension 28 of the tubular tail 22 and is closed at one end by a cap 32. A smoke-producing projectile is similarly constructed and differs only in the rature of the composition ignited by the time fuse. In another form, Fig. 7, the grenade contains an illuminating charge 35 housed within a container 36 which is connected to a parachute 37. The container and parachute are ejected from the projectile by a charge 39 which is ignited during flight by the time fuse 17. A wick 38 enables the charge 35 to be ignited by the charge 39. One or more wads 42 of asbestos are interposed between the charge 39 and container 36 to prevent any damage to the latter during the ejecting operation.
