Abstract: 497,389. Ammunition receptacles ; cartridge - clips. BEESTON, W. H. (Lambert, C. F.) Nov. 13, 1937, No. 31203. [Class 9 (i)] [Also in Groups XVII and XXII] An ammunition receptacle for air-tight stowage of loaded cartridges or powder bags comprises a casing with reinforcing rings, one at or near each end, so constructed that when two receptacles are stowed alongside one another either pointing the same way or in opposite directions, the rings register and keep the axes of the receptacles parallel, said rings having bearing faces of larger diameter and small diameter, the bearing faces of larger diameter contacting with each other when the receptacles point the same way, and the bearing faces of smaller diameter contacting with each other when the receptacles point in opposite directions, in which latter case the axes of the receptacles are closer together. In addition, an improved lid is provided. In the form shown, the casing 2, Fig. 1, is made with a base part 3 of cast or drawn aluminium welded to the body portion at 4a. A reinforcing ring 22 is secured to the base by an embossed portion 23, which may be additionally bulged at spaced points. The ring 22 has tapered sides rising from bearing faces 16a, 17a of smaller diameter to the periphery of the ring which constitutes a bearing face of large diameter. A ring 9, 12 is similarly secured to the front end of the casing, and comprises inner inclined sides 14, 15 rising to shoulders 16, 17 of lesser diameter than the periphery of the ring 9, 12. The periphery constitutes the bearing faces of larger diameter, and the shoulders 16, 17 the bearing faces of smaller diameter. The two parts 9, 12 of the ring are connected together by a number of webs 13, to accommodate which, the periphery of the ring 22 is made with a corresponding number of notches 26. When two such receptacles are stacked one against the other in opposite directions as shown in Fig. 10, the shoulders 16, 17 bear against the shoulders 16a, 17a; and when the receptacles point in the same direction as in Fig. 11, the peripheral faces of the rings bear against each other and the axes of the receptacles are more distant. In this latter case, a flexible or sinuous fitting or conduit 29 is placed within the groove formed by the rings 9, 12 to prevent longitudinal displacement of the receptacles. The shapes of the reinforcing rings may be slightly modified, and these rings may be partly formed by bulges from the casing wall. The cover comprises a sheet metal liner 10 fitted into a rim 8 secured in the mouth of the ring 9 by a bayonet joint. In a modification, Fig. 15, a bail 42 is connected by trunnions 46 to sockets 45 in a shouldered part of the cover 43, and the trunnions have outer cams 41 adapted to be inserted into side hooks 40, after which, when the bail is swung down, the cams 41 tighten the cover against the end of a reinforcing ring 34. The hooks 40 are formed at the outer ends of small plates 38 fastened in a notch in the ring 34 and flush with its periphery. The cover can be made to act as a cartridge clip by being provided with two spaced lugs 47 and an opposite spring pawl 49 for engaging the rim 48 of the cartridge.
