Abstract

Typically, in automatic electrostatographic reproducing apparatus toner or developer material is transported from a toner supply to a development housing by means of an auger transport. A common problem associated with auger transports is the impaction and clogging of the auger flute crevasses. The drawing illustrates in cross-section one technique in which this difficulty may be minimized. In the drawing, one revolution of the transport auger 12 is serrated in sawtooth fashion and an interference member 14, such as a .010 with thick polyester sheet such as Mylar, is mounted to the auger tube 10 so that it rides in and out of the auger flute serrations producing a ratchet effect that transfers a shockhibration to the transport auger. The shock vibration prevents the pipeline tube walls from caking and impacting with toner or developer material. In addition, the interference piece acts to bias the auger downwardly to further clean the system of potential auger flutekube wall impacting.
