Voltage regulator for generators

Claim 1

IN AN ELECTRICAL GENERATING SYSTEM FOR AN AUTOMOTIVE VEHICLE, THE COMBINATION COMPRISING, AN ALTERNATOR INCLUDING OUTPUT TERMINALS AND A FIELD WINDING, A RECTIFIER CONNECTED TO SAID OUTPUT TERMINALS, AN ELECTRICAL STORAGE BATTERY CONNECTED ACROSS SAID RECTIFIER, A RELAY HAVING TWO SETS OF CONTACTS AND A WINDING, SAID WINDING HAVING A SELECTED NUMBER OF TURNS, AN IGNITION SWITCH, SAID RELAY WINDING BEING CONNECTABLE TO SAID STORAGE BATTERY AND SAID RECTIFIER THROUGH SAID SWITCH, A VOLTAGE LIMITER, ONE OF SAID SETS OF CONTACTS BEING CLOSED BY THE MAGNETIC FIELD CREATED BY CURRENT FLOW THROUGH THE SELECTED NUMBER OF TURNS OF SAID RELAY WINDING WHEN SAID IGNITION SWITCH IS CLOSED AND BEING CONNECTED TO ENERGIZE SAID FIELD WINDING FROM SAID STORAGE BATTERY THROUGH SAID VOLTAGE LIMITER WHEN SAID IGNITION SWITCH IS CLOSED, AN INDICATOR LAMP, THE OTHER SET OF CONTACTS BEING CONNECTED TO ENERGIZE SAID INDICATOR LAMP WHEN THE OUTPUT VOLTAGE OF SAID ALTERNATOR IS INSUFFICIENT TO CHARGE SAID BATTERY, SAID OTHER SET OF CONTACTS BEING OPENED BY THE MAGNETIC FIELD CREATED BY CURRENT FLOW THROUGH THE SELECTED NUMBER OF TURNS OF SAID WINDING WHEN THE OUTPUT VOLTAGE OF THE ALTERNATOR EXCEEDS THE TERMINAL VOLTAGE OF THE BATTERY.
