Electrical ignition apparatus using a high voltage breakdown and a condenser followup through the ignition gap

Claim 1

IN APPARATUS OF THE CLASS DESCRIBED, A DIRECT CURRENT SOURCE OF ELECTRICAL ENERGY, FIRST AND SECOND STEP-UP TRANSFORMERS HAVING PRIMARY WINDINGS IN PARALLEL CIRCUITS CONNECTED TO SAID SOURCE, A VIBRATOR OPERATIVELY INTERRUPT THE SAID SOURCE AND OPERABLE TO INTERMITTENTLY CONNECTED TO CIRCUITS THROUGH SAID PRIMARY WINDINGS, A CONDENSER CONNECTED TO THE SECONDARY WINDING OF SAID FIRST TRANSFORMER AND CHARGEABLE THEREBY IN INCREMENTS TO A VOLTAGE IN EXCESS OF THE SOURCE VOLTAGE, A THIRD TRANSFORMER HAVING ITS PRIMARY WINDING CONNECTED TO SAID CONDENSER, A SPARK GAP FOR CONTROLLING THE DISCHARGE OF SAID CONDENSER THROUGH SAID LAST-NAMED PRIMARY WINDING, AN IGNITER GAP CONNECTED WITH THE SECONDARY WINDING OF SAID THIRD TRANSFORMER WHICH STEPS UP THE VOLTAGE OF SAID CONDENSER DISCHARGE TO A VALUE GREATER THAN THE NORMAL BREAKDOWN VOLTAGE OF THE IGNITER GAP, A SECOND CONDENSER IN CIRCUIT WITH THE SECONDARY WINDING OF SAID SECOND TRANSFORMER AND CHARGEABLE THEREBY IN INCREMENTS TO A VOLTAGE BELOW THE NORMAL SPARK-OVER VOLTAGE OF THE IGNITER GAP, AND MEANS CONNECTING SAID SECOND CONDENSER TO THE IGNITER GAP THROUGH SAID SECONDARY WINDING OF THE THIRD TRANSFORMER WHEREBY SAID SECOND CONDENSER DISCHARGES ACROSS THE IGNITER GAP WHEN THE LATTER IS IONIZED BY THE DISCHARGE OF SAID FIRST-NAMED CONDENSER.
