A rotary piston conveyor comprising a plurality of interengaged rotors in which at least one rotor is driven and, in turn, drives the other rotors. Each pair of adjacent rotors have spiral vanes which mesh to form the conveyor path as the rotors rotate. The degree of interengagement of the flanks or edges of the meshed vanes determine the efficiency of the conveyor path formed by the meshed vanes for any particular material or groups of material. Hence the rotors are adjustable to vary the interengagement of the vanes. The clearance between vanes in a direction parallel to the shaft determines the size or cross-section of the conveyor path. Hence, the rotors are longitudinally adjustable with respect to each other to vary the clearance. The adjustment device includes a split gear on the driven rotor and means for making each of the two adjustments as well as markings or indicia which may be read against a marker to show the degree of adjustment.
