The oil pump is of the twin gear rotary pattern, entirely con-structed of bronze with steel driving shaft, and is driven from themain shaft by a worm and worm gear. The gear box under the boiler is the housing for enclosing thebevel gears, which transmit the motion from the horizontal driv-ing shaft to the vertical shaft supporting the burner head. On the bottom of the burner head is constructed a primary airfan of the propeller type, which handles all the air supplied to theburner. At the top of the hub is constructed the two sections of CRUDE OIL AS KLEL IN LOW PRESSURE HEATINC. SYSTEMS 419 the secondary fan, which are of the multivane type, and deliver theair both above and below the oil spray. At the bottom of the oil atomizing cup, is a trough undercut toretain constantly a thin film of oil, which by capillary attraction,connects with the film of oil fed to the burner cup from the supply. Fig. pipe in the hollow spindle. This forms a continuous ring of oilwhen the head is in motion, and causes absolutely even distributionof the oil over the entire periphery of the burner cup at the pointwhere the oil leaves the head and enters the fire box. This con-dition is absolutely necessary for a perfectly even fire that willburn with a steady flame and without puffing. The top of the headis carried by the continuation of the oil feed spindle, and is sta-tionary and covered with a cap of fireproof compound. The head end of the bed plate under the boiler has four sup-porting legs carrying cast iron floor plates, for the support of thefire brick floor of the fire box. Immediately below the floor platesare two grooved guides, carrying an adjustable air damper, by which 420 (KVDE OIL AS FUEI, IX LOW PRESSURE HEATING SYSTEMS the air supply to the fans is controlled, and the amount of air accu-ra
