ABSTRACT:
A cyclically operable clutch in which first and second driven gears are provided with interrupted gear tooth sections normally located opposite a motor driven drive gear. The second gear is operably connected to a cyclically operable driven mechanism and the first gear is spring urged to rotate relative to the second gear. A latch normally maintains the first gear out of mesh with the drive gear. Upon release of the latch, the first gear is spring advanced into mesh with the drive gear and a lost motion connection between the driven gears transmits rotation to the second gear to advance the latter into mesh with the drive gear.
