Function selecting mechanism

Claim 1

A FUNCTION-SELECTING DEVICE COMPRISING A REVERSIBLE ELECTRIC MOTOR HAVING A FORWARD-RUNNING CIRCUIT AND A REVERSE RUNNING CIRCUIT; A FIRST RELAY SWITCH HAVING A PAIR OF NORMALLY OPEN CONTACTS, A PAIR OF NORMALLY CLOSED CONTACTS AND A RELAY COIL; A SECOND RELAY SWITCH HAVING A PAIR OF NORMALLY OPEN CONTACTS AND A RELAY COIL; SAID NORMALLY CLOSED CONTACTS BEING CONNECTED IN SERIES WITH SAID NORMALLY OPEN CONTACTS OF SAID SECOND RELAY SWITCH, A SOURCE OF POWER, SAID SERIES CONNECTED CLOSED AND OPEN CONTACTS BEING SERIES CONNECTED BETWEEN SAID SOURCE OF POWER AND SAID FORWARD-RUNNING CIRCUIT, SAID NORMALLY OPEN CONTACT OF SAID FIRST SWITCH BEING CONNECTED IN SERIES WITH AND BETWEEN SAID REVERSE-RUNNING CIRCUIT AND SAID POWER SOURCE WHEREBY CLOSURE OF SAID SECOND SWITCH CONTACTS CAUSES SAID MOTOR TO RUN IN A FORWARD DIRECTION AND CLOSURE OF THE NORMALLY OPEN CONTACTS OF SAID FIRST SWITCH CAUSES SAID MOTOR TO RUN IN A REVERSE DIRECTION, THIRD, FOURTH, FIFTH AND SIXTH MANUALLY OPERABLE SWITCHES EACH HAVING A PAIR OF NORMALLY OPEN CONTACTS AND A PAIR OF NORMALLY CLOSED CONTACTS, EACH THIRD, FOURTH, FIFTH AND SIXTH SWITCHES INCLUDING MEANS FOR CLOSING THE OPEN CONTACTS THEREOF WHEN THE CLOSED CONTACTS THEREOF ARE OPENED; SEVENTH AND EIGHTH MANUALLY OPERABLE SWITCHES EACH HAVING A PAIR OF NORMALLY OPEN CONTACTS; FIRST, SECOND AND THIRD SOLENOIDS; A SOURCE OF UNIDIRECTIONAL VOLTAGE; SAID FIRST SOLENOID BEING CONNECTED IN SERIES WITH SAID FIRST RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID THIRD SWITCH, AND SAID SOURCE OF VOLTAGE; SAID FIRST SOLENOID ALSO BEING CONNECTED IN SERIES WITH SAID SECOND RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID FOURTH SWITCH AND SAID SOURCE OF VOLTAGE; SAID SECOND SOLENOID BEING CONNECTED IN SERIES WITH SAID FIRST RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID FIFTH SWITCH, THE NORMALLY CLOSED CONTACTS OF SAID THIRD FOURTH SWITCHES, RESPECTIVELY, AND SAID SOURCE OF VOLTAGE; SAID SECOND SOLENOID ALSO BEING CONNECTED IN SERIES WITH SAID SECOND RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID SIXTH SWITCH, THE NORMALLY CLOSED CONTACTS OF SAID THIRD AND FOURTH SWITCHES, RESPECTIVELY, AND SAID SOURCE OF VOLTAGE; SAID THIRD SOLENOID BEING CONNECTED IN SERIES WITH SAID FIRST RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID SEVENTH SWITCH, THE NORMALLY CLOSED CONTACTS OF SAID THIRD, FOURTH, FIFTH AND SIXTH RESPECTIVELY, AND SAID SOURCE OF VOLTAGE; SAID THIRD SOLENOID ALSO BEING CONNECTED IN SERIES WITH SAID SECOND RELAY COIL, THE NORMALLY OPEN CONTACTS OF SAID EIGHTH SWITCH, THE NORMALLY CLOSED CONTACTS OF SAID THIRD, FOURTH, FIFTH AND SIXTH SWITCHES, RESPECTIVELY, AND SAID SOURCE OF VOLTAGE; WHEREBY SAID SOLENOIDS AND SAID RELAY SWITCHES MAY BE SELECTIVELY ENERGIZED IN RESPONSE TO SELECTIVE OPERATION OF SAID THIRD, FOURTH, FIFTH, SIXTH, SEVENTH OR EIGHTH SWITCHES.
