ABSTRACT:
A continuously adjustable liquid mixing device for intermixing selectively adjustable volumes of several liquids comprises a body for holding a plurality of volumes of the liquids including a recess at an upper end. A mechanism is provided for drawing up the volumes of liquid into the body and thereafter expelling the same from a lower end. A volume adjusting selecting mechanism is provided for at least one of the volumes including a rotary element mounted in the recess and frictionally engaging a wall surface thereof for retaining a selected volume that is desired. A rotary drive system is provided for rotating the volume adjustment mechanism and is readily accessible externally of the body for convenient manipulation to select a desired volume. The drive system is movable between an outer operating position for easy manipulation and a retracted position when not in use.
