Apparatus for dispensing particulate material has a substantially enclosed rigid housing with longitudinally disposed walls and parallel side walls having an opening in the housing for dispensing particulate material therefrom and a flexible sheet-like inner liner conformable to at least some of the longitudinal walls of the housing, one end of which is attached to a portion of the housing the other end of which is attached to a take-up roll for the inner liner which conforms to the longitudinal walls when the housing is filled with particulate material. The portion of the housing to which the inner liner is attached, the take-up roll and the dispensing opening are disposed relative to each other such that as the sheet-like inner liner is taken up by the take-up roll the particulate material is transported by the inner liner toward the dispensing opening and dispensed therethrough. In a preferred embodiment, the particulate dispenser is a developer housing for an electrostatographic printing machine.

Particulate material dispenser

An apparatus in which successive flexible sheets are advanced from a stack. The stack of sheets are held in a substantially vertical orientation. Successive outermost sheets from one side of the stack are fed, in seriatim in a direction substantially opposed to the direction of the gravitational force exerted thereon. The stack of sheets is moved toward a sheet feeder so as to position successive outermost sheets of one side thereof in a feeding relationship therewith. In addition, the stack holder moves from an operative position, in which the sheets are in a sheet feeding relationship, to an inoperative position for loading a new stack therein.

Sheet feeder-stacker

An apparatus in which successive flexible sheets are advanced from a stack. One edge of the stack of sheets is supported rollably in a substantially vertical orientation. Successive outermost sheets are fed from one side of the stack. The stack of sheets moves toward a sheet feeder so as to position successive outermost sheets of one side thereof in a feeding relationship therewith.

Sheet feeder stack support

A sorting apparatus in which a sheet loading station is arranged to advance sheets into individual sheet receiving members of one of at least two groups of sheet receiving members. The other group of sheet receiving members is positioned at one of two sheet unloading stations. After loading and unloading sheets from the respective groups of sheet receiving members, the loaded group of sheet receiving members moves to the other sheet unloading station as the unloaded group of sheet receiving members returns to the sheet loading station.
