ABSTRACT:
An apparatus for apportioning powdered material into each of a series of containers is disclosed which includes a powdered material hopper having a dispensing opening and a rotatable filling head contiguous to the dispensing opening. The rotatable filling head includes a plurality of radially situated chambers each having an open outer end for displacement between the material hopper and the series of containers. A conventional pneumatic source is provided for assisting the filling and emptying of the chambers during the apportioning process. Within each chamber, the volume of powdered material received is defined by a piston having a porous surface. The piston engages a threaded stem longitudinally fixed in position yet rotatable about its longitudinal axis to effect displacement of the piston head and support longitudinally within the chamber. A seal is provided at the radially inner end of the threaded stem to ensure positive pneumatic action through the porous piston surface.
