Abstract: 489,221. Ammunition receptacles ; cap closures. CLAYTON & LAMBERT MANUFACTURING CO. Nov. 18, 1936, No. 31534. Convention date, Nov. 20, 1935. [Class 9 (i)] [Also in Group XVII] An ammunition or cartridge container of tubular form and of circular cross-section adapted to receive a single round of ammunition or cartridge comprises a main receptacle and a cover therefor, the receptacle being provided with one or more annular reinforcing portions so shaped as to interengage with complementary portions on other containers when stacked and so prevent longitudinal shifting of the containers relatively to one another, the walls of the container being only a little larger in diameter than the main body portion of the ammunition or cartridge. The containers may be stacked in alternate reversed positions. Fig. 2 shows a construction in which the aluminium receptacle for receiving the cartridge 6 is formed of three parts, a bottom 5, a body 4 and a top ring 3, welded together at 13 and 14. The bottom 5 is formed with a projecting annular spacing member 9 whilst the body 4 is provided with annular indentations 15, 16 which serve properly to position the cartridge within the container. The ring member 3, which is arranged to terminate below the top 7 of the cartridge is formed with tongue and groove members 11, 12 which co-operate with similar members on adjacent receptacles when in the storage magazine. The receptacle is closed by a cover 2 having a flange member 17 adapted to be screwed to the ring 3 as shown or engaged therewith by means of a bayonet joint, Fig. 4 (not shown). An annular cork gasket 19 is positioned between the top 7 of the cartridge and inner part of the cover 2 which is formed with a handle 20 which, if desired, may be partially located within a depression in the outer face of the cover, Fig. 3 (not shown). Fig. 6 shows a modified construction of receptacle adapted to receive a standard type of fixed ammunition comprising the cartridge 6, cap end 7 and projectile 8a. In this arrangement, the ring 3 is formed as a separate member being held in place by the extension 4a of the body 4 and is formed with a flange 24 which co-operates with the cover 2 to form a bayonet slot connection. The shell is centred by means of the indentation 15 and also by a plate 28 having a central tapered aperture. The ring 3 is formed with a single annular groove 27 and the bottom portion 5 with an outwardly flaring annular projection 29 which is shaped so as to fit within the groove 27 of an adjacent container when the containers are stacked with the cap ends reversed as shown in Fig. 10, the construction of receptacle shown in this figure being similar to that shown in Fig. 6 with the exception that the receptacle is designed to receive a cartridge only and its cover 2 may be provided with a bail 34 instead of a handle 20. Clip extractors 35, shown in dash-dot lines in Figs. 6 and 10 may be accommodated in a cut-away portion of the gasket 19. Fig. 7 shows a modified form of cover 2 in which the inner surface thereof is formed as a stamped sheet metal unit 30, the casting which is formed around this unit being adapted to move relatively thereto so that, when the cover is turned, the lower end 31 of the unit will be forced against the gasket 18 without moving laterally relative thereto.
