Claim 1
Independent Claim
161 words
A CONTROL MECHANISM FOR AN INFINITELY VARIABLE CONE PULLEY TRANSMISSION HAVING TWO PAIRS OF AXIALLY MOVABLE CONE PULLEY DISCS AND A FLEXIBLE MEMBER CONNECTING THE SAME, COMPRISING FOUR LEVER MEMBERS ARRANGED IN PAIRS AND ADAPTED TO ACT UPON SAID PULLEY DISCS, SAID LEVER MEMBERS BEING DISPOSD SYMMETRICALLY WITH RESPECT TO A FIRST PLANE PERPENDICULAR TO THE AXES OF ROTATION OF THE PULLEY DISCS AND ALSO SYMMETRICALLY WITH RESPECT TO A SECOND PLANE PARALLEL TO SAID AXES AND PERPENDICULAR TO SAID FIRST PLANE AND LOCATED MIDWAY BETWEEN SAID AXES, MEANS MOUNTING SAID LEVER MEMBERS SO AS TO BE INDEPENDENTLY PIVOTABLE AT THEIR INNER ENDS ABOUT AXES DISPOSED WITHIN SAID SECOND PLANE, AND MEANS OPERATIVELY CONNECTED WITH THE OUTER ENDS OF THE SAID LEVER MEMBERS FOR SIMULTANEOUSLY ADJUSTING SAID LEVER MEMBERS BY EQUAL AMOUNTS OF PIVOTAL MOVEMENT, THE LEVER MEMBERS OF EACH PAIR OF LEVER MEMBERS ON THE SAME SIDE OF SAID FIRST PLANE BEING PIVOTED IN OPPOSITE DIRECTIONS BY SAID ADJUSTING MEANS.
