CANADA LUMBERMAN AND WOODWORKER 25 lighter rolls but the same size, 12-inch x 36-inch. The other two sec- tions are 10-inch x 30-inch and 8-inch x 30-inch. The live roll drives are all below and are taken from countershafts with belts The edger 'is a Pacific Coast type, 8-inch x 72-inch, with steam lift rolls and is driven by a 100 h.p. motor direct connected to the saw arbor-. The feed is driven independently from below, having two speeds forward and one reverse. â ,â Behind the edger is a line of rolls m three sections extending to the tail end of mill, with transfers to the gang and resaw. The main line of live rolls also has transfers to gang and resaw. rlhe slasher has 24 saws, spaced 12VA-inch centres, to cut all slabs and edgings into 12-inch stove wood, and is driven by a 50 h.p. motor direct con- nected to the saw arbor, with a flexible coupling. The chains are driven by friction and gears, belted 'from saw arbor. The wood falls from the slasher into a conveyor and is distributed automatically into 17 wood bins, each holding a good waggon load. The gang is a 10-inch x 32-inch pony, Wickes Bros, make, and feeds towards the head end of the mill, the lumber falling onto the transfer to trimmers without any handling. The gang is used tor cutting all the best grades of flooring, ceiling, etc. Ihe resaw is a 6-foot pony Allis brand, with roller attachment, the rolls and pressure ter the lumber has passed the planer, it falls onto transfer chains, and then onto a set of live rolls which convey it back on to the same line of sorting chains, which continue on for another 75 feet, the lumber being sorted onto trucks to be conveyed to retail yard or shipping platform A 50 h.p. motor drives a 45-inch fan and the live rolls and transfers around the sizer. The sizer itself is driven by a 60 h.p. motor direct connected with flexible coupling. ... , The basement of the mill is high, 16-foot posts, giving plenty of room for the conveyors and drives. The system adopted was to group the drives as far as possible by belting from a motor to a short shaft and taking as many drives off it as could be conveniently reached, using frictions, wherever possible, to make the system flexible. All the convevors empty into the furnace feed conveyor, so that all the refuse goe* through the boiler house. The basement contains the large 200 h.p. motor to drive the big band, a 100 h.p. motor to drivo the resaw, three 40 h.p. and three 15 h.p. motors Each motor has an oil starter and an automatic circuit breaker The power house is a frame building, iron clad, 44 feet x 60 feet, with an ell 30 x 26 feet, The boilers at present consist of three 72- inch x 18-foot return tubular boilers 145 pounds pressure, with foun- dation for another boiler of the same size. The boilers rest on con-

This resaw is used for splitting door stock, panels, etc., and any 2-inch stock that may need to be split into 1-mch A return set of rolls are installed and a transfer alone is needed to make it a return system It was thought however, that it could be kept going, splitting, and the return would not be needed The teed is towards the head end of the mill and the lumber falls onto the transfer to the trimmers without handling. The lumber timers are the old stvle push trimmer on account ot the lumber being cut shoit in the log. Lumber up to 24 feet long can be trimmed, but it woi ks best for 20 feet and shorter. Course of Lumber in the Mill. After passing the trimmers, the lumber goes onto the first sec- tion, 50 feet long, of the sorting chains where al thejj^onnft ag- ing and door stock is taken off onto three wheeled B^on^trucks. The remainder drops onto a set of chains controlled by t.ie man ^d- ing a 10-inch x 30-inch Stetson & Ross ready sizer This planer-will tawe, with two men feeding, any size lumber up to 12-inch wide S i b. LB. from 1-inch to 10-inch thick or 1-mch shiplap up to 12-meh wide changing instantly from shiplap to any size dimension so that a piece of 8-inch x 12-inch can follow a piece of 1-mch x 6-mch shiplap. At- crete foundation, resting on a solid bed of piles, the piles being cut off 15 feet below where the brickwork starts. The induced draft system has a fan 144-inch diameter, driven by an engine direct connected to shaft. Back ot the boilers a solid crib wall 6 inches thick, separates the boiler house and ^ ^neratmg room. The generator set at present consists of a 500 k.w. turbo generator of the Allis-Chalmers-Parsons make, a 27% k.w. engine- dHven exciter and a 10 k.w. motor-driven exciter. The engine-driven exciter is also used to light the sawmill and buildings adjacent to, ,t A slate switchboard holds a complete set of instruments and a Tyrrell vol regnla or. The system used is 3-phase. 60 cycle, alternating cur- rent So volts. The generator being a 480 volt machine. Another 500 k.w. set will be installed so that ample power will be availabde to, additions to the factory plant. Two mam circuits lead ti 0111 the swhchboard, one to a distributing room in the basement ot the mill nd the other 600 feet to another distribution ^jgjj The cables are led to heavy copper bus bars and taken thiough tuses to the different, motors. The wiring is all in conduit. The filing room is situated in the roof of the milk and is driven by a 71/X p motor, a complete line of Covel machinery being installed.
