It takes less than an hourto get up two hundred pounds of steam,and when the engine is standing thefire may be put out entirely and thenreignitcd within an hour from the heatof the brick arches in the fire-box. STEAMBLOWER. In Starting th; Fire the Fireman Turns on the Steam-Blower in the Smoke-Box. The Air-Blower Motor and the Fuel-Conveyor Motor Are Then Started and Fuel and Air Enter theCombustion Furnace Which Is an Ordinary Locomotive Fire-Box with a Fire-Brick Floor places a piece of lighted oil-waste in thefurnace. Immediately following this hestarts the air-blower motor and thefuel-con\e\-or motor. The screw-con-\xyoT forces the fuel into the fuel feeder,where it meets the air driven by theblower. The fuel and air are then dri\-enthrough a commingler, and this mixturethen enters the combustion furnace,which is the ordinary locomoti\e fire-boxfitted with a fire-brick floor in place ofgrate bars, where the lighted oil-wasteignites it. The fire-box is provided withbrick arches and air inlets. There is aslag pan instead of the usual ash i^an. The regulating mechanism controllingair and fuel is within reach of the fireman,so he need never have occasion to leave T The Wastage of
