Self-starting synchronous motor

Claim 1

IN A SYNCHRONOUS MOTOR, THE COMBINATION WITH A FIELD STRUCTURE INCLUDING A COIL, AND A PERMANENT-MAGNET ROTOR STARTING AND RUNNING IN EITHER DIRECTION ON ENERGIZATION OF SAID COIL, OF A DIRECTIONAL DRIVE CONTROL HAVING A FIRST ROTORDRIVEN MEMBER WITH A ROTARY AXIS, A SECOND FIXED MEMBER, A ONE-WAY CLUTCH HAVING TWO COMPANION ELEMENTS OF WHICH A FIRST ELEMENT IS TURNABLE ABOUT SAID AXIS AND THE SECOND ELEMENT LOCKS SAID FIRST ELEMENT AGAINST ROTATION IN ONE DIRECTION RELATIVE TO SAID SECOND ELEMENT, WITH SAID FIRST MEMBER AND FIRST ELEMENT CONSTITUTING THE PART OF A FIRST UNIT AND SAID SECOND MEMBER AND SECOND ELEMENT CONSTITUTING THE PARTS OF A SECOND UNIT, OF WHICH ONE PART OF ONE OF SAID UNITS IS TURNABLE RELATIVE TO THE OTHER ARE THEREOF ABOUT SAID AXIS AND THE PARTS OF THE OTHER UNIT ARE NON-TURNABLE RELATIVE TO EACH OTHER ABOUT SAID AXIS, AND A SPRING RELATIVE TO EACH OTHER ABOUT SAID AXIS, AND A OPERATIVELY CONNECTING THE PARTS OF SAID ONE UNIT AND YIELDINGLY OPPOSING ROTATION OF SAID ONE PART RELATIVE TO SAID OTHER PART IN SAID ONE DIRECTION, WITH THE NORMAL ROTOR DRIVE OF SAID FIRST MEMBER BEING IN THE OPPOSITE DIRECTION; AND A MOTOR LOAD OF BACK-UP TYPE APPLIED TO THE ROTOR VIA SAID FIRST MEMBER, WHEREBY IN IDLE CONDITION OF THE ROTOR SAID FIRST ELEMENT IS BACKED INTO SAID LOCKED RELATION WITH SAID SECOND ELEMENT BY SAID MOTOR LOAD, WITH SAID SPRING BEING ARRANGED TO HAVE ADEQUATE RESILIENCEY FOR DEFLECTION INTO EXACT COUNTERBALANCE WITH SAID MOTOR LOAD IN IDLE CONDITION OF THE ROTOR SO THAT AN REENERGIZATION OF SAID COIL THE ROTOR ENCOUNTERS NO LOAD IN ANY REPOSE POSITION.
