Abstract: An apparatus for dispensing particulate material or a viscous liquid which consists of a cylindrical material container section, a frustoconical chamber and an end plate mounted so as to separate the container and chamber. The container and chamber are rotated about an inclined longitudinal axis by an electric motor and gear drive; while the end plate is stationary. The end plate defines a circumferential inlet for passing material from the container to chamber outlet and agitates the material to prevent lumping. An agitating probe mounted in the circumferential inlet and a fixed scouring brush are also employed to ensure proper flow.
