Igntion system for internal combustion engine

Claim 1

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE COMPRISING, IN COMBINATION (A) A SOURCE OF ELECTRIC CURRENT; (B) TWO POWER CIRCUITS CONNECTED TO SAID SOURCE, EACH CIRCUIT INCLUDING (1) A PRIMARY WINDING, AND (2) SWITCH MEANS HAVING A CONDUCTIVE AND A NONCONDUCTIVE CONDITION AND BEING CONDUCTIVELY CONNECTED TO SAID SOURCE AND TO SAID WINDING FOR SERIAL PASSAGE OF CURRENT FROM SAID SOURCE THROUGH SAID WINDING AND SAID SWITCH MEANS IN SAID CONDUCTIVE CONDITION OF SAID SWITCH MEANS; (C) A SOURCE OF A SEQUENCE OF ELECTRIC TRIMING PULSES; (D) SWITCH ACTUATING MEANS CONNECTED TO SAID SOURCE OF TIMING PULSES AND TO ONLY A SINGLE SELECTED ONE OF SAID SWITCH MEANS OF SAID POWER CIRCUITS. (1) COUPLING CIRCUITRY CONNECTING SAID SELECTED ONE OF SAID SWITCH MEANS TO THE SWITCH MEANS OF THE OTHER POWER CIRCUIT IN A DEPENDENT MUTUAL COUPLING MANNER, (2) MEANS FOR BIASING SAID SELECTED SWITCH MEANS TO ITS NONCONDUCTIVE CONDITION IN THE ABSENCE OF THE APPLICATION THERETO OF A TIMING PULSE, (3) SO THAT THE ENERGIZATION OF THE SELECTED SWITCH MEANS IN RESPONSE TO THE APPLICATION THERETO OF A SINGLE TIMING PULSE IS EFFECTIVE TO SIMULTANEOUSLY DE-ENERGIZE THE SWITCH MEANS OF SAID OTHER POWER CIRCUIT AND SO THAT THE DE-ENERGIZATION OF THE SELECTED SWITCH MEANS IN RESPONSE TO THE ABSENCE OF THE APPLICATION THERETO OF A TIMING PULSE IS EFFECTIVE TO ENERGIZE THE SWITCH MEANS OF SAID OTHER POWER CIRCUIT, (E) TWO SECONDARY WINDINGS INDUCTIVELY COUPLED TO SAID PRIMARY WINDINGS RESPECTIVELY AND CONSTITUTING RESPECTIVE TRANSFORMERS THEREIN; AND (F) A SPARK PLUG IN CIRCUIT WITH EACH SECONDARY WINDING.
