Dealers in Principal Cities and Towns in the United States and Canada Representation in numerous foreign countries IRON FIREMAN Automatic Coal Burners "Forced Underfiring" Principle --Iron Firemen "Forced Underfiring" is based on the scientific principle of feeding fuel to the fire from below, under forced draft. From the con veyor screw coal enters the firebox under the fire and is gradually forced up ward into the flame. As the coal ap proaches the fire, it is gradually heated. The volatile gases are distilled off in the presence of an excess of oxygen and are thoroughly ignited while passing through the incandescent fuel bed. This insures complete combustion. The ash is fused into clinkers which are easily removed. Advantages--Iron Fireman saves money and in creases heating plant efficiency in four major ways: (1) Cuts fuel costs; (2) Reduces labor costs; (3) Provides Steady, Typical Installation Down even heat or Draft Firebox Boiler power; (4) Elimi nates the smoke nuisance. Installation and Sizes--Iron Fireman is made in a range of hopper and bin-feed sizes for commercial heating and power boilers and also for homes. It can be installed quickly in practically any solid fuel boiler or furnace, old or new. Machines are shipped complete from the factory. All parts are standard and interchangeable. Features of Design and Construc tion--Construction and operation of the Iron Fireman are characterized by sim- plicity throughout. Outstanding fea tures of design and construction are:' (1) Pressed steel construction. (2) Special patented transmission--three speeds and neutral. Gears run in bath of oil. (3) Electric motor--standard make. (4) V-belt drive. (5) Safety shear pin protects mechanism from damage. (6) Quiet ball bearing fan supplying forced draft to fire. (7) Automatic fire banking damper--conserves fuel and holds fire in proper condition when stoker is idle. (8) Positive pneumatic fume eliminator--an auxiliary air supply that insures positive movement of all gases through the fire. (9) Volumeter that supplies exactly the amount of air needed for perfect com bustion regardless of fuel bed con ditions or type of coal used. (10) Sectional retort especially design ed to allow for heat expansion. (11) Dead plates of heavy iron and ribbed. (12) Sec tional, self-clean ing tuyere blocks. Typical Installation Four Drum Water Tube Boiler (13) Conveyor screw cast of special Iron Fireman alloy steel from one-piece pattern. (14) Automatic electric controls designed for and used exclusively on Iron Fireman. Automatic Controls--Iron Fireman starts and stops at the command of sensi tive, accurate automatic controls.

Other directing controls include pressure regulators, hot water and furnace regulators, and the "Timetactor," a device which runs the Iron Fireman during pre determined intervals in order to keep the fire alive* during'mild weather.
