Transistor oscillator spark ignition apparatus for internal combustion engines

Claim 1

SPARK IGNITION APPARATUS FOR INTERNAL COMBUSTION ENGINES, COMPRISING A DIRECT CURRENT SOURCE, AN IGNITION TRANSFORMER HAVING A CORE, A PRIMARY WINDING ON THE CORE, A SECONDARY WINDING ON THE CORE CONNECTIBLE THROUGH A DISTRIBUTOR TO THE SPARK PLUGS OF THE ENGINE IN TURN, AND A CONTROL WINDING ON SAID CORE, A MONOSTABLE OSCILLATOR PRODUCING UPON EACH OPERATION THEREOF A SPARK IN THE SECONDARY CIRCUIT AS A RESULT OF RISING CURRENT IN SAID PRIMARY WINDING, SAID MONOSTABLE OSCILLATOR INCLUDING A TRANSISTOR HAVING ITS EMITTER AND BASE INTERCONNECTED THROUGH SAID CONTROL WINDING, SAID CONTROL WINDING PROVIDING FEEDBACK TO SAID TRANSISTOR, A SERIES CIRCUIT CONNECTED TO SAID SOURCE, SAID SERIES CIRCUIT INCLUDING SAID PRIMARY WINDING AND THE COLLECTOR AND EMITTER OF SAID TRANSISTOR, AND A SECOND SERIES CIRCUIT CONNECTED TO SAID DIRECT CURRENT SOURCE, SAID SECOND SERIES CIRCUIT INCLUDING SAID PRIMARY WINDING, A CAPACITOR, AND AN ENGINE-DRIVEN INTERRUPTER OPERATING SAID OSCIALLTOR IN TINED RELATIONSHIP TO THE ENGINE TO PRODUCE SPARKS AT SAID PULUGS IN TURN, SAID APPARTUS FURTHER INCLUDING A DIODE CONNECTED ACROSS SAID PRIMARY WINDING TO ABSORB BACK ELECTROMOTIVE FORCE AFTER PRODUCTION OF EACH SPARK, AND A RESITOR AND A SWITCH CONNECTED IN SERIES WITH SAID INTERRUPTER TO SAID DIRECT CURRENT SORUCE, SAID SWITCH CONTROLLING OPERATION OF THE SPARK IGNITION APPARATUS, AND SAID CAPACITOR DISCHRGING TROUGH SAID DIODE AND SAID RESISTOR WHEN A SPAK IS PRODUCED.
