Abstract
An epicyclic drive train arrangement having a plurality of output drive members which may be selectively driven from a single input drive member. A frame equipped with two pawls is operated by a single solenoid and spring combination. During successive cycles of solenoid operation, a selected pawl engages its mating gear by action of a solenoid plunger rod. The action prevents rotation of the selected gear while the pawl is engaged. The unselected pawl disengages its mating gear thereby allowing it to freely rotate. Multiple epicyclic drive train arrangements may be configured so as to drive a plurality of sheet feeding apparatuses in an electrophotographic printing machine.
