ABSTRACT:
A device for efficient storage, measuring, and dispensing of several powdered and/or particulate materials holds these materials in a side-by-side array of compartments. Each compartment has a storage chamber and a measuring chamber. Dispensing is prompted by gravity and agitation, for orderly flow of each material through its two chambers as their drain gates are selectively opened. Simultaneously with the opening of the gate under either chamber, a dc eccentric motor acts on that chamber to break up any clumps of material that might impede free flow. Each of the two chambers has its own motor. The storage chamber array is structurally separate from the measuring chamber array, so that the two chambers can vibrate separately, further improving free flow.
