A 14-inch accumulator, 14-footstroke, with loaded casing to secure a pressure of 1,000pounds per square inch is used, and differential pumpsoperated automatically according to requirements. Thesepumps can work at a speed of 150 revolutions without the yard to the elevator and with turn tables reaches allthe various points where material and work are to bedelivered. In the light work foundry which is 200 feetlong by 50 feet wide, there is one of the most complete sets ofpulley moulding machines and appurtenances that wasever designed; the interchangability is something wonder-ful.
