Abstract

An incremental motion mechanism which utilizes first and second one-way clutches attached to the output shaft of the mechanism. The first one-way clutch is used to prevent back up of the output member, while the second one-way clutch is used to incrementally rotate the output shaft. First and second solenoids and associated linkage under the control of a controller are used for adjusting the extent of rotation of the output shaft.
