FIRST COMMERCIAL DYNAMO USED IN THE USA FOR ARC LIGHTING.(REF.2) IT WAS DESCRIBED AS A DOUBLE MACHINE, EACH SERIES OF COILS, WITH IT'S COMMUTATOR, BEING CAPABLE OF USE INDEPENDENT OF THE OTHER. IN FACT, THIS WAS NOT SO: THE TWO CURRENTS GENERATED ARE JOINED IN ONE EXTERNAL CIRCUIT. THE ARMATURE DESIGN PRESENTED CONSIDERABLE RESISTANCE TO ROTATION. IT ALSO PRODUCED HEAT SUFFICIENT TO MELT SEALING WAX. (REF.1 & 3) WHEN WILLIAM WALLACE DEMONSTRATED HIS GENERATOR IN 1878 HE CONNECTED IT TO EIGHT ARC LAMPS, EACH HAVING A RADIANCE OF APPROX. 4,000 CANDLES. AMONG THOSE PRESENT TO VIEW WALLACE'S MACHINE WAS THOMAS EDISON. (REF.2) - Area Notes
