Conversion. Electric shaver plant. This New England whose normal product is electric dry shavers is now turning out parts for machine tools which will find their place in the war production effort. This bank of Norton grinders which formerly ground motor shafts are now grinding small parts for tools. Tolerances on the war work are only .002 inches whereas the former work demanded much closer tolerances up to .0002 inches. The conversion was accomplished by putting on new grinding wheels, by minor changes in the head and by increasing the feed of the cutting solution. Schick Inc., Stamford, Connecticut

New oversize trailer for war workers. Interior of the new oversize bus trailer built almost entirely of non-critical material and designed by Office of Defense Transportation and War Production Board officials with cooperation of private companies. Containing eighty-seven seats(twenty-four drop seats will be installed later), the trailer has a seating capacity nearly three times that of an ordinary city bus and twice that of the largest type of street car. It's one solution to the problem of transporting defense workers from cities to outlying industrial plants

Conversion. Electric shaver plant. This Norton type C six-inch semi-automatic cylindrical grinder in a New England plant used to grind motor shafts for the firm's normal production of electric dry shavers. It is now grinding spring collets which are used in turning machines to hold the work being turned. Such machines are vitally needed for the war production effort. The conversion of the machine was accomplished by replacing the one-inch vitrified aluminum oxide wheel shown here with a three-inch wheel and by enlarging the feed of the cutting solution. Tolerances on this war work are only .002 inches as compared with the tolerances on the normal production of .0002 inches (see pix #D-2974). Schick Inc., Stamford, Connecticut

Conversion. Copper and brass processing. Pickling lengths of copper water tube in a brass and copper mill. After annealing, or softening by heat to reduce brittleness and allow further drawing, tubes are "pickled" in a sulphuric acid solution to remove oxide and scale that result from the anneal. Bundles of the tubes are picked up by electric cranes and transported from the pickle to a rinse bath of water. The tubes are then returned to the drawbench for re-drawing down to smaller diameters.

Conversion. Electric shaver plant. This worker in a New England plant that normally produces electric dry shavers is now busy turning out spring collets for machine tools to be used in war production. On this Norton type C six-inch semi-automatic cylindrical grinder, he used to turn out rotor shafts for the motor of the shaver. To convert his machine to the larger grinding job, it was necessary only to exchange the normal one-inch vitrified aluminum oxide wheel for a three-inch wheel and to increase the feed of the cooling solution. This worker was used to working to a tolerance of .0002 inches on the motor shafts so he finds it simple to attain the comparatively rough tolerance of .002 inches required on this war work.

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. 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.

Conversion. Electric shaver plant. This Norton type C six-inch semi-automatic cylindrical grinder in a New England plant normally turns out these motor shafts for the firm's electric shavers. It has since been converted to the grinding of spring collets that are used in machine tools being produced to aid the war production effort. The conversion was easily accomplished by replacing the one-inch vitrified aluminum oxide wheel shown here with a three-inch wheel and by enlarging the feed of grinding solution. In this operation normal tolerance is desired (see pix #D-2975). Schick Inc., Stamford, Connecticut
