ABSTRACT:
A sheet feeding device for feeding single sheets of paper from the bottom of a stack of paper sheets. The device includes a feed tray angled at approximately 60.degree. with the horizontal and a substantially rigid paper drive member cooperating with a plurality of differentially yieldable retard members. By successively increasing the normal pressure on the members or by changing their coefficients of friction, increments of increasing or decreasing retarding force are provided. Uniform frictional forces between individual sheets are provided by a bail weight.
