ABSTRACT:
A filling machine for repeatedly dispensing predetermined amounts of particulate material comprises a stationary hopper having two spaced-apart spouts; a motor-driven horizontally rotatable upper plate beneath the spouts and having four groups of receiving holes therethrough and a stationary bottom plate beneath the upper plate and having two groups of dispensing holes therethrough. As the upper plate is rotatably driven, the receiving holes align with the spouts, are filled with material, and then align with the dispensing holes through which the material then falls. A sweeper member above the upper plate directs excess material accumulated on the upper plate into emptied receiving holes approaching a spout. A weighted sleeve on each spout slidably engages the upper plate to inhibit material leakage. Each group of receiving holes has a cup plate on the underside of the upper plate with apertures in registery with the receiving holes and slidably engageable with extension tubes from the receiving holes. The cup plates slide on the rotating bottom plate to inhibit material leakage.
