Claim 1
Independent Claim
170 words
IN AN AUTOMATIC CONTROL CIRCUIT FOR AN INTERNAL-COMBUSTION ENGINE HAVING ELECTRICAL MOTOR-STARTING MEANS INCLUDING A STARTER MOTOR, AND A SOLENOID SWITCH CONNECTED TO ENERGIZE AND DEENERGIZE THE STARTER MOTOR, THE COMBINATION COMPRISING A TEMPERATURE-RESPONSIVE SWITCH ARRANGED TO OPEN AND CLOSE UPON PREDETERMINED UPPER AND LOWER LIMITS OF ENGINE TEMPERATURE, A SOURCE OF ELECTRICAL POWER CONNECTED TO ONE SIDE OF SAID TEMPERATURE-RESPONSIVE SWITCH, A NORMALLY CLOSED ENGINE-OIL-PRESSURE-RESPONSIVE SWITCH ADAPTED TO OPEN UPON RISE TO NORMAL OPERATING OIL PRESSURE AND CONNECTED IN SERIES WITH SAID TEMPERATURERESPONSIVE SWITCH AND SOURCE, NORMALLY OPEN ACTUATOR CONTACTS CONNECTED TO SAID SOLENOID SWITCH AND IN SERIES WITH SAID TEMPERATURE-RESPONSIVE AND OIL-PRESSURE SWITCHES TO ENERGIZE THE STARTER MOTOR UPON SIMULTANEOUS CLOSING OF SAID CONTACTS AND SWITCHES, AN ELECTRICALLY OPERATED ACTUATOR MECHANISM CONNECTED IN SERIES WITH SAID TEMPERATURE-RESPONSIVE AND OIL-PRESSURE SWITCHES AND OPERATIVELY CONNECTED TO SAID CONTACTS TO REPEATEDLY OPEN AND CLOSE THE LATTER, A CIRCUIT-BREAKER OVERLOAD SWITCH CONNECTED IN SERIES WITH SAID TEMPERATURE-RESPONSIVE AND OILPRESSURE SWITCHES, AND A SHORT-CIRCUITING TIME-DELAY RELAY CONNECTED ACROSS SAID TEMPERATURE-RESPONSIVE AND OILPRESSURE SWITCHES.
