Developer storage and dispenser apparatus










Image Number 2 for United States Patent #4739907.

A cylindrical developer storage and dispensing cartridge with a dispensing opening at one end has an integral developer transport mixing and antibridging member rotatably supported within the container which has a first coiled spring element having a cross section substantially the same as the cross section of the container and freely rotatable therein which is wound in the direction to transport developer along its length toward the dispensing opening and a second coiled spring element having a cross section substantially smaller than the first spring element but being substantially concentrically positioned and being attached to the first element but wound in a direction opposite to the first spring element to provide a counter rotating motion relative to the first spring element. The second spring element extends through the central portion of the first spring element and has longitudinal arms at each end attached to at least one of the coils at each end of the first spring element to provide support to the first spring element against compression.
