Abstract
Dispensing apparatus is provided for simultaneously dispensing metered quantities of a plurality of materials into a common receptacle. Pump modules each containing a plurality of individual pump members are arranged in a rectangular pattern, between a base plate and a drive plate. The drive plate is raised and lowered, toward and away from the base plate, by a pair of drive screws. The plurality of individual pump members are thus simultaneously operated to dispense different materials into a common receptacle, at the same time.
