Three-inch A.A. cartridge cases. Brass discs are conveyed to a cupping press that forms them into the brass cups from which cartridge cases for three-inch antiaircraft shells are drawn. They look harmless enough but each one will be a potential headache for Axis fliers by the time it comes off the production line

Conversion. Beverage containers to aviation oxygen cylinders. The first step in the manufacture of high-altitude-flying shatterproof oxygen cylinders in the metal department of a large rubber factory is the forming or stamping of the shell. Stainless steel sheets are blanked or cut into discs(left foreground). Before stamping, these discs are drawn through rolls where a drawing compound is added to both sides to facilitate the forming of the shell. The 750-ton toggle press, shown above, forms a half cylinder in one powerful stroke. Once the half cylinder is formed, it is trimmed and the value-fitting hole is punched into the spherical dome. A cleaning operation later removes the drawing compound. The cylinder halves are now ready for the various welding operations. Firestone, Akron, Ohio

Shaping the tire with "saucers." Spinning discs which are delicately controlled by movable arms smooth out each layer of fabric as it is added to the growing carcass, and curves around the sidewall and bead with considerable pressure. In the center foreground, one of these saucers may be seen as this tire builder maneuvers it around the sharp corner of the tire drum. In the right foreground two others pull across from the center to the edges to smooth out each layer. Firestone (General Tires), Akron, Ohio

Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells are drawn from brass cups which are themselves formed from flat discs. After they come from the cupping press they are washed to provide clean surfaces for future operations and are conveyed in basket trucks to annealing furnaces. Annealing will remove any strains set up in the metal by the cupping press operations
