Abstract

In electrostatographic printing machines, toner is typically replaced in the development system by being supplied to the system from a toner container such as a bottle on a continuing basis. One conventional way of doing this is to provide a disposable toner bottle of generally circular cross section which contains an internal wire auger to move toner horizontally toward the dispensing opening and out of the bottle. In such practice one of the difficulties frequently encountered is that the very small particle size toner material becomes compacted into agglomerates and further into much larger clumps and may even in fact form a bridge extending over the dispensing opening. The Figures illustrate a toner bottle wherein a "thumper" feature is added to the bottle to rovide a more uniform dispense rate and provide a more

of the coil spring shape of the auger 12, a ramp 14 is added to the end cap 16 to cornpress the auger toward the drive end of the bottle 10 as it rotates. As it rotates the auger is forced to compress as it rises up the ramp feature. As the end of the auger passes the ramp, the energy stored in the compressed coil snaps it toward the end...
