Abstract
A rotary driven drum-shaped dispenser for fluid materials is disclosed. The drum is comprised of a plurality of nested rings each of which has a plurality of arcuate channels through which the fluid material is passed during rotation of the drum. An adjustable valve is positioned at the inlet end of each flow channel. The end bells of the drum have covered access openings for filling the drum with fluid material to be dispensed. A divider within the drum separates the drum chamber into two chambers so that separate materials may be dispensed simultaneously without pre-mixing.
