Abstract
478,257. Ammunition cartridges. ARMSTRONG, J. J. V. (General Hydraulic Co.) July 15, 1936, No. 19598. [Class 9 (i)] The mouth plug 2 of an ordnance cartridge consists of a relatively rigid outer portion 10 consisting, for instance of finely ground cork of relatively high tensile strength, and an inner portion 11 of relatively soft and frangible material, such as coarsely ground cork. The outer portion is sufficiently hard to withstand impacts during the loading operation, while the presence of the frangible portion ensures that the plug will break up into small fragments upon firing. In the construction shown, the portion 10 is in the form of an annular ring which is formed with a reduced portion which fits into the end 9 of the cartridge case 6 to which it is cemented. The inner portion or ,core 11 is cemented or glued to the portion 10. The exposed surface of the plug may be impregnated with graphite or like material, to reduce friction between the plug and projectile 5 and between the plug and bore of the gun. In a modification, the outer portion of relatively rigid material is moulded to form the complete nose of the plug.
