Abstract
A device for receiving and dispensing metered quantities of loose material. The dispenser includes an upright open hopper having a rotatable metering shaft journaled below downwardly converging hopper walls. A helical feed groove or a series of indentations aligned in a helical path along the metering shaft receive material from the hopper upon rotation of the shaft and discharge it in the metered quantities below. Wipers are provided on opposite sides of the metering shaft and extend from the hopper walls to rub against the shaft periphery in order to control the amount of material received and delivered through the helical groove or indentations.
