ABSTRACT:
A high speed sheet stacking device for stacking documents on edge as they are serially ejected from a sheet transport apparatus into preselected sorting pockets. A pair of spaced-apart paddle wheels coaxially disposed subjacent to the pocket are rotatively driven through apertures formed therein, displacing the documents to the back side of the pocket in a serially stacked arrangement. The paddles remain outside of the pocket until advanced in rotative steps of 90.degree. responsive to the passing of a document past a predetermined point enroute to the stacking pocket. A thin wire spring secured to the outer end of each paddle aids in displacing the documents during stacking and remains bent through the pocket floor in holding contact against the stacked sheets after the rotative stepping is completed.
