Upon turning on any of the light switches the engine is quickly started. This is accomplished by the use of a three-wire system, the switches being arranged so the third wire makes connection first. This third wire connects a small six-volt storage battery with a starting motor that is directly connected to the generator, thereby starting the generator and engine. The engine will continue running as long as one light is burning. The writer considers the ideal system to be one that can operate with a hit and miss engine without storage battery and still give steady light. Such a plant would include a generator with a moderate size fly wheel to prevent rapid fluctuation of the speed of the generator, and a voltage regulator to take care of changes in speed of longer duration. It must be a complete plant alone, but so designed that a storage battery can be added at any time, with no change in the system except simple adjustments. Probably all systems that are being sold will give fair satisfaction if handled intelligently. Usually, the more automatic the system, the more a person must know to be able to keep the system properly adjusted. The more simple the system the less attention it will need although it may not give quite as satisfactory light as the automatic systems when they are working properly. THE "MIDGET" COIL.
