Abstract: A base supports a hopper for the storage of the particulate material to be dispensed in measured amounts. A stationary discharge tube in place in the base defines an opening for the entry of hopper stored material. A control tube is slidably mounted within the discharge tube and defines a second opening which upon control tube elevation registers with the discharge tube opening to admit material flow into the control tube. Said control tube carries, in a removable manner at its lower end, a measuring tube which is interchangeable with other measuring tubes, each of a different length, to enable dispensing of various amounts of material from a measuring chamber defined by the joined tubes. An O-ring couples the control tube and the measuring tube in a removable manner. The control tube additionally includes an insert or plug shaped member so as to prevent bridging and voids in the particulate measured.
