One advantage in havingthe Bessemer process is that the cupolacan be used for either steel or ironfoundry work as required. This cupolais, of course, additional to their regulariron foundry melting equipment. Closelaboratory control is also effected inthe use of materials and alloys so thatdifferent grades of steel and iron cast-ings can be produced as required. Thereare two 5-ton Northern overhead electrictravelling cranes in the steel foundrywhich can operate in the iron foundrywhen necessary in case of breakdown or. STEEL FOUNDRY CLEANING ROOM. OWEN SOUND PLANT 28 CANADIAN FOUNDRYMAN for helping out on extra heavy the steel foundry is thesand mixing room in connection withwhich is a sand handling plant of con-siderable merit. The new silica sandand clay are elevated by a verticalbucket conveyor into large overheadstorage tanks. From the tanks the ma-terials drop through chutes and areaccurately measured before being mix-ed in the 6 foot motor-driven rotarv ing and casting floors give a properrouting of work through the shop. Themoulders, therefore, do nothing elsethan actual moulding work. The cleaning room 50 ft. x 100 ft.,with storage in second storey, is equippedwith motor-driven tumblers, a sandblast, pneumatic chipping tools, are stored in large fire-proofrooms conveniently adjoining mouldingfloors. The storage is divided into sec-
