Filed: 1916-11-28
Abstract: 127,001. Lanser, A., and Marbais, D. Oct. 11, 1916, [Convention date]. Tanks.-Relates to petrol tanks that are selfsealing when pierced by projectiles. The metal tank is surrounded by a layer of felt, leather, cork, &c. and an outer casing of one or more layers of india-rubber. Any burrs formed in the metal, when perforated, are thus prevented from affecting the india-rubber casing. In a modification, the india-rubber may be covered by a syrupy substance insoluble in the liquid contained in the tank. In another modification, three layers of india-rubber are used, the middle layer consisting of a number of squares of rubber touching one another, so that they become displaced when perforated and tend to close the hole. When there is no rigid exterior wall, the rubber casing may be enclosed in a net to prevent deformation by the liquid if perforated. When there is a rigid exterior wall, a layer of red fibre or equivalent substance is interposed between this wall and the rubber casing. Reference has been directed by the Comptroller to Specification 126,087.
