Abstract
An apparatus in which particles are dispensed from the open end of a chamber. A member is positioned interiorly of the chamber and periodically agitated in response to particles being dispensed therefrom. Agitation of the member prevents bridging and caking of the particles in the chamber and facilitates the flow of the particles therefrom.
Claims20
An apparatus for dispensing particles, including:
- means, defining an open ended chamber, for storing a supply of particles therein;
- a member disposed in the chamber of said storing means;
- and
- means, disposed in the open end of the chamber of said storing means, for dispensing particles from the chamber, said dispensing means comprises a rotatably mounted cylindrical member having a plurality of spaced depressions therein, and at least one protrusion extending outwardly from the depression and arranged to periodically engage said member during the rotation of said cylindrical member to agitate said member to prevent the bridging and caking of particles in the chamber of said storing means so as to facilitate the flow of particles from the open end of the chamber of said storing means.

An electrophotographic printing machine of the type having a development system for depositing particles on an electrostatic latent image recorded on a photoconductive member, wherein the improvement includes:
- means, defining an open ended chamber, for storing a supply of particles therein;
- a member disposed in the chamber of said storing means;
- and
- means, disposed in the open end of said storing means, for dispensing particles from the chamber to the development system, said dispensing means comprises a rotatably mounted cylindrical member having a plurality of spaced depressions therein, and at least one protrusion extending outwardly from depression and arranged to periodically engage said member during the rotation of said cylindrical member to agitate said member to prevent the bridging and caking of particles in the chamber of said storing means so as to facilitate the flow of particles from the open end of the chamber of said storing means to the development system.
