. Canadian forest industries July-December 1912. Lumbering; Forests and forestry; Forest products; Wood-pulp industry; Wood-using industries. 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. The triple drum sander is driven by a 20 570 motor, direct connected through flexible coupling to the countershaft on machine. The 70 in. Sturtevant low power blower is operated by a 40 double end motor at 475 , the shaft of motor being extended sufficiently for the fan blades to be directly mounted on each end of shaft. This blower serves readily all the machines given in the fol- lowing schedule: 1-40 1,150 motor, belted to Fig. 501 American 54 in. band resaw, with 1-3 1,750 motor, operating Fig. 511 double jointing attachment, which is direct connected to the cylinders by belt. 1-40 475 double end motor, operating a double 70 in. Sturtevant low power
