A rear stop for a device for feeding sheets one at a time from a stack of sheets with the feeding device comprising a frame supporting a front gauge, front and rear stack supports and the rear stop, means for shifting the leading edges of each of the sheets against the front gauge and means reciprocated between a pair of positions for feeding the lowermost sheet of a stack beneath the front gauge characterized by the rear stop being mounted for vertical movement in the frame and the stop having a plurality of abutment surfaces disposed at different levels so the rear stop has a stair step cross-sectional configuration. A preferred embodiment of the rear stop is formed by a stack of plates which are arranged to form the stair step configuration. In order to provide different spacing between the abutments, the thicknesses of the plates of the stack may be different. |
