Fast indexing mechanisms for CVT's

An indexing mechanism that can be used to move an item of a pre-determined weight, the indexing mechanism comprising

• a) an index bar that has lengthwise cavities into which a lock can be inserted;
• when said lock is inserted into a selected cavity of the lengthwise cavities, linear movements of said item is locked;
• and when said lock is not inserted into the selected cavity of the lengthwise cavities, said linear movements of said item is allowed;
• b) means for controlling said lock;
• c) an output shaft;
• d) a rotation to linear converting mover mechanism, which converts a rotational input provided by the output shaft to the linear movements of said item and said index bar;
• e) an actuator lever that can rotate about a pivot point that is co-centric with a center of said output shaft;
• f) a clutch that can controllably engage and disengage said actuator lever with said output shaft;
• when said actuator lever is engaged with said output shaft, a rotation from said actuator lever is transferred to said output shaft;
• and when said actuator lever is disengaged with said output shaft, said actuator lever is allowed to rotate relative said output shaft;
• g) means for rotating said actuator lever that can be used to rotate said actuator lever clockwise and counter-clockwise;
• h) a first stop and a second stop, said first stop is used to limit the clockwise rotations of said actuator lever, and said second stop is used to limit the counter-clockwise rotations of said actuator lever;
• rotating said actuator lever from a position where said actuator lever is in contact with said first stop to a neutral position, which is a mid-point position between said first stop and said second stop, causes said index bar to move from the selected cavity of the lengthwise cavities to a next cavity of the lengthwise cavities, and rotating said actuator lever from a position where said actuator lever is in contact with said second stop to said neutral position also causes said index bar to move from the selected cavity of the lengthwise cavities to another next cavity of the lengthwise cavities,
• i) a first tension spring and a second tension spring;
• said first tension spring is attached to said actuator lever in a manner so that the first tension spring can be tensioned by rotating said actuator lever from said neutral position towards said first stop;
• and in a manner so that tension of the first tension spring can be used to rotate said actuator lever from said first stop towards said neutral position;
• and said second tension spring is attached to said actuator lever in a manner so that the second tension spring can be tensioned by rotating said actuator lever from said neutral position towards said second stop;
• and in a manner so that tension of the second tension spring can be used to rotate said actuator lever from said second stop towards said neutral position.
