Sequential motor control for mechanized feeding

Claim 1

AN ELECTRIC CIRCUIT FOR SEQUENTIALLY STARTING AND STOPPING A PLURALITY OF ELECTRIC MOTORS, SAID CIRCUIT INCLUDING A PAIR OF MOTOR POWER LINES EXTENDING FROM A SOURCE OF ELECTRIC POWER, A MOTOR STARTER CIRCUIT FOR EACH MOTOR INCLUDING A MOTOR STARTER RELAY HAVING A MOTOR STARTER SOLENOID AND HAVING MOTOR STARTER CONTACTS FOR CONNECTING SAID MOTOR TO SAID POWER LINES WHEN SAID MOTOR STARTER SOLENOID IS ENERGIZED, A PAIR OF CONTROL LINES EXTENDING FROM A SOURCE OF ELECTRIC POWER, A START SEQUENCE RELAY FOR EACH MOTOR HAVING A START SEQUENCE SOLENOID CONNECTED AT A FIRST END THEREOF TO A FIRST OF SAID CONTROL LINES AND HAVING FIRST, SECOND AND THIRD SETS OF NORMALLY OPEN START SEQUENCE CONTACTS AND A FOURTH SET OF NORMALLY CLOSED START SEQUENCE CONTACTS ADAPTED TO REMAIN CLOSED UNTIL SAID FIRST SET OF START SEQUENCE CONTACTS BECOMES CLOSED UPON ENERGIZATION OF SAID START SEQUENCE SOLENOID, A STOP SEQUENCE RELAY FOR EACH MOTOR HAVING A STOP SEQUENCE SOLENOID CONNECTED AT A FIRST END THEREOF TO SAID FIRST CONTROL LINE AND HAVING A FIRST SET OF NORMALLY OPEN STOP SEQUENCE CONTACTS AND SECOND AND THIRD SETS OF NORMALLY CLOSED STOP SEQUENCE CONTACTS, SAID THIRD SET OF STOP SEQUENCE CONTACTS BEING ADAPTED TO REMAIN CLOSED UNTIL SAID FIRST SET OF STOP SEQUENCE CONTACTS BECOMES CLOSED UPON ENERGIZATION OF SAID STOP SEQUENCE SOLENOID, AN ELECTRICAL CONNECTION FOR EACH MOTOR FROM A POWER SOURCE TO SAID MOTOR STARTER SOLENOID BY WAY OF SAID THIRD SET OF START SEQUENCE CONTACTS, AN ELECTRICAL CONNECTION FROM A SECOND OF SAID CONTROL LINES TO A FIRST SIDE OF EACH OF SAID FIRST START SEQUENCE AND FIRST STOP SEQUENCE CONTACTS, AN ELECTRICAL CONNECTION FROM A SECOND SIDE OF SAID START SEQUENCE SOLEONID TO A FIRST SIDE OF SAID SECOND STOP SEQUENCE CONTACTS, AN ELECTRICAL CONNECTION FROM A SECOND SIDE OF SAID STOP SEQUENCE SOLENOID TO A SECOND SIDE OF SAID FIRST STOP SEQUENCE CONTACTS AND TO A FIRST SIDE OF SAID THIRD STOP SEQUENCE CONTACTS, A COMMON ELECTRICAL CONNECTION BETWEEN A SECOND SIDE OF SAID SECOND START SEQUENCE CONTACTS AND SAID THIRD STOP SEQUENCE CONTACTS, A COMMON ELECTRICAL CONNECTION BETWEEN SECOND SIDES OF SAID FIRST AND FOURTH START SEQUENCE CONTACTS AND A SECOND SIDE OF SAID SECOND STOP SEQUENCE CONTACTS, COMMON STARTER CONTROL MEANS SELECTIVELY OPERABLE TO CONNECT A FIRST SIDE OF SAID FOURTH SET OF START SEQUENCE CONTACTS OF THE FIRST MOTOR TO BE STARTED TO SAID SECOND CONTROL LINE, START JUMPER LINES FROM SAID SECOND SIDE OF SAID FOURTH START SEQUENCE CONTACTS OF EACH OF SAID MOTORS EXCEPT THE LAST TO BE STARTED TO THE FIRST SIDE OF THE FOURTH START SEQUENCE CONTACTS OF THE NEXT MOTOR TO BE STARTED, COMMON STOP CONTROL MEANS SELECTIVELY OPERABLE TO CONNECT A FIRST SIDE OF SAID SECOND START SEQUENCE CONTACTS OF THE FIRST MOTOR TO BE STOPPED TO SAID SECOND CONTROL LINE, AND STOP JUMPER LINES FROM SAID SECOND SIDE OF SAID FIRST STOP SEQUENCE CONTACTS OF EACH OF SAID MOTORS EXCEPT THE LAST TO BE STOPPED TO THE FIRST SIDE OF SAID SECOND START SEQUENCE CONTACTS OF THE NEXT MOTOR TO BE STOPPED.
