The plant covers approximately 75,000 sq. ft., em- ploys 90 men and uses about 500,000 ft. of lumber annually, which is manufactured into various kinds of interior and exterior finish. This plant formerly operated its own power plant, but after being destroyed by fire, installed entire new wood working machinery, operated by motors in the most up-to-date styUroi drive. Practically all the machines are direct connected as sho/^n in the schedule fol- lowing. / All motors are of the Fairbayks-Mor^c manufacture, and are 3-. No. 2—S. A. Wood Inside Moulder, Driven by 25 H. P. Fairbanks-Morse Motor phase, 440-volt, 60-cycle. The total horse-power of motors installed is 294 of which 246 operates on individual drive, and 48 on group drive as shown in schedule. The principal point of interest in connection with the electrical equipment of this plant, is the extreme limit of speed, which is rather unusual for this class of motor. The planers have the motors directly attached to the cylinders, motors operating cylinders at a speed of 3,600 , motors being directly connected through flexible coup- lings. The double surfacer shown in the illustration, is operated by a 20 motor at a speed of 3,600 , direct connected to the upper cylinder through flexible coupling. The lower cylinder of this ma- chine is belted to a 7y± 1,750 motor. While there are some few cases where the planer cylinders are operated by induction motors direct connected to cylinders, the di- rect connecting to the cylinder of the double surfacer is entirely new in this territory, and is proving successful and giving excellent sat- isfaction.
