Claims

1. A CONSTANT SPEED MECHANISM COMPRISING A CONSTANTLY OSCILLATING INERTIA MEMBER HAVING REGULAR CYCLES COMPRISED OF TWO INACTIVE AND TWO ACTIVE PERIODS, AN INTERMITTENTLY ACTUATED MEMBER MOVABLY MOUNTED ADJACENT SAID INERTIA MEMBER AND HAVING ALTERNATIVE OPERATING POSITIONS, SAID INTERMITTENTLY ACTUATED MEMBER HAVING REGULAR CYCLES COMPRISES OF TWO INACTIVE AND TWO ACTIVE PERIODS CORRESPONDING TO THOSE OF SAID INERTIA MEMBER, SAID INTERMITTENTLY ACTUATED MEMBER BEING MOVABLE DURING SAID ACTIVE PERIODS AND STATIONARY DURING SAID ACTIVE PERIODS, FIRST MAGNETIC MEANS ON SAID INERTIA MEMBER HAVING A PREDETERMINED FIRST FIELD OF INFLUENCE, SECOND MAGNETIC MEANS ON SAID INTERMITTENTLY ACTUATED MEMBER HAVING A PREDETERMINED SECOND FIELD OF INFLUENCE, SAID FIRST AND SECOND MAGNETIC MEANS BEING POSITIONED TO ACCOMMODATE EFFECTIVE MAGNETIC INTERACTION OF SAID FIRST AND SECOND FIELDS AT PREDETERMINED LIMITED ACTIVE PORTIONS ONLY OF THE OSCILLATING EXCURSION OF THE INERTIA MEMBER DURING SAID ACTIVE PERIODS, THE FIELDS OF INFLUENCE OF SAID FIRST AND SECOND MAGNETIC MEANS BEING SO RELATED THAT SAID FIRST FIELD ACTS UPON SAID SECOND FIELD AT THE COMMENCEMENT OF SAID ACTIVE PERIODS TO INITIATE MOVEMENT OF SAID INTERMITTENTLY ACTUATED MEANS FROM ONE ALTERNATIVE OPERATING POSITION TOWARD THE OTHER AT REGULAR INTERVALS DETERMINED BY THE NATURAL FREQUENCY OF SAID INERTIA MEMBER, AND EXTERNAL ENERGY INPUT EANS ACTING UPON SAID INTERMITTENTLY ACTUATED MEMBER DURING SAID ACTIVE PERIODS TO EFFECT MOVEMENT OF SAID MEMBER FROM ONE ALTERNATIVE OPERATING POSITION TOWARD THE OTHER, SAID SECOND FIELD OF INFLUENCE DURING SAID ACTIVE PERIOD ACTIVING UPON SAID FIRST FIELD OF INFLUENCE TO IMPART TO SAID INERTIA MEMBER A PREDETERMINED INCREMENT OF ENERGY TO SUSTAIN THE OSSCILLATORY MOTION OF SAID INERTIA MEMBER, SAID FIRST MAGNETIC MEANS MOVING BEYOND THE EFFECTIVE INFLUENCE OF SAID SECOND MAGNETIC MEANS DURING SAID INACTIVE PERIODS, SAID INACTIVE PERIODS COMMENCING AT THE ARRIVAL OF SAID INTERMITTENTLY ACTUATED MEMBER AT ONE OF ITS ALTERNATIVE OPERATING POSITIONS.
