It is impossible to leave the switch on the lower unfused lugs,owing to its construction, which will immediately throw the switchout if the hand is removed, and the small fuses completely protectthe motor from any overload that might occur when it is in opera-tion, and solenoid will trip the switch upon any failure of the cur-rent, and the motor automatically stops. siimplex burner Fig. 4 shows a cut of the latest type of the Simplex burner is jrear driven from an electric motor installed on a Ff^«h=i^.

AS FUEL IX LOW PRESSURE HEATING SYSTEMS 421 cast iron bed plate directly in front of the boiler, and all rotatingshafts are mounted in the highest grade of ball bearings for endand lateral thrust. The revolving centrifugal atomizing cup is entirely open at itsdischarge end, and has polished surface free of all fan blades againstwhich heavy oil may lodge. The fuel oil is introduced at the bot-tom of the cup in such a manner as to be caught by the centrifugalforce in a thin film, thus keeping the rotating cup insulated fromthe reflex heat, and as the oil climbs from the outlet in the bottomof the cup and is discharged to the fire zone, it is superheated bythe reflex heat to the flash point, before it reaches the wall of thebuilt-in fire box. The cup revolves at a speed sufficient to break upand atomize the oil, thereby evenly distributing same to the firezone, the atomization
