Conversion. Beverage containers to aviation oxygen cylinders. Before completion of the fourth and final welding operation in the manufacture of shatterproof oxygen cylinders for high altitude flying, all straps are subjected to physical tests to determine the strength of the weld. Occasional radiographic inspections are made to insure the quality of workmanship after the two halves of the cylinder are brought together in this atomic welding machine and made one unit. Here, the operator has just completed the union and is about to remove the whole cylinder. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. Before completion of the fourth and final welding operation in the manufacture of shatterproof oxygen cylinders for high altitude flying, all straps are subjected to physical tests to determine the strength of the weld. Occasional radiographic inspections are made to insure the quality of workmanship and materials after the atomic welding machine has brought the two halves of the cylinder together and made into one unit. The operator, looking through a specially designed dark safety glass, rotates the shell by sight to insure a perfect and uniform union of the two halves. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. Four major welding operations are essential to the manufacture of shatterproof oxygen cylinders for high altitude flying. In the first, the circumferential straps are securely welded to the cylindrical portion to prevent tearing of the metal. The process is shown above, taken in the metal division of a large Eastern rubber factory. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. After the circumferential straps are welded to the cylindrical portion, in the metal division of a large Eastern rubber factory, rough edges and accumulated weld scale are removed by a skilled workman. The twin rotary brushes, shown above, do their work on the inside and outside of the cylinder in the same operation. This process is required in the manufacture of shatterproof oxygen cylinders for high altitude flying. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. Once the two-half cylinders are joined together into a complete shatterproof high altitude flying oxygen cylinder on the production line of a huge rubber factory now producing metal essential for the Army, all traces of inside weld scale must be removed to prevent contamination of oxygen. In this process, a special chemical solution is drawn through the cylinder at controlled temperature and all foreign matter is removed. Firestone, Akron, Ohio

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

Conversion. Beverage containers to aviation oxygen cylinders. With the outside and inside of non-shatterable oxygen cylinder for high altitude flying complete, several rigorous tests are applied to guarantee safety. Every cylinder off the production line of the metal division of a large Eastern rubber factory is hydrostatically tested at 800 pounds pressure, twice the pressure maintained in the cylinder under normal use, to test the strength of the welding. It is then given air test at 400 pounds pressure as shown above. Here, an attendant is placing a cylinder into a steel compartment filled with water before the pressure is applied. By means of a hand crank, the inspector rotates at all points. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. After they are stamped on the huge toggle press in the metal division of a large rubber factory, these cylindrical domes which make up half of a shatterproof oxygen cylinder, are placed on a large conveyor where they are carried to workmen who will apply the circumferential and longitudinal straps. Cylinders are used for high altitude flying as a source of oxygen. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. Removing of non-shatter-chemical solution tank at a rubber factory now producing metal essential for the Army. This bath, which follows the removal of the weld scale, gives the inside of the cylinder a further cleaning and removes all chemicals which may remain from the previous operation. A satin-like surface, absolutely sterile and free from foreign matter, is made permanent in this operation. The cylinder is now also immune to attack from corrosion and other deteriorating elements.
