Flashing lamp circuit using a transistor oscillator

Claim 1

A LAMP FLASHER AND OUTRAGE INDICATOR CIRCUIT COMPRISING: A SOURCE OF DIRECT CURRENT HAVING ONE SIDE CONNECTED TO GROUND; A TRANSISTOR OSCILLATOR HAVING A VOLTAGE BUILD-UP CIRCUIT INCLUDING THE COLLECTOR AND EMITTER ELECTRODES OF A TRANSISTOR AND A TIMING DELAY COIL CONNECTED IN THAT ORDER TO THE SOURCE AND THROUGH A RETURN SWITCHING CIRCUIT TO GROUND; THE OSCILLATOR HAVING A CHARGING CIRCUIT INCLUDING FIRST RESISTANCE MEANS, SECOND RESISTANCE MEANS, AND A CAPACITOR CONNECTED IN SERIES ACROSS THE TRANSISTOR AND COIL, THE JUNCTION POINT OF THE SECOND RESISTANCE MEANS AND CAPACITOR BEING CONNECTED TO THE BASE ELECTRODE OF THE TRANSISTOR; THE TIMING RELAY HAVING A FIRST SET OF NORMALLY OPEN CONTACTS ADAPTED TO CLOSE UPON THE OPERATION OF THE RELAY TO CONNECT THE JUNCTION POINT OF THE FIRST AND SECOND RESISTANCE MEANS TO THE GROUND RETURN CIRCUIT; AND A SECOND SET OF DOUBLE THROW LOAD SWITCHING CONTACTS ON THE TIMING RELAY ADAPTED TO SWITCH SIGNAL LAMP LOADS ACROSS THE SOURCE ALTERNATELY THROUGH A FIRST SELECTED LAMP LOAD AND THEN THROUGH A SECOND SELECTED LAMP LOAD FOR ALTERNATING FLASHING OF THE LOADS.
