Title: Split worm for screw press

Abstract: An interrupted flight screw press is provided, especially in regions of heavier wear, with one or more longitudinal split worm bodies. The bodies have axially extending end flanges which hook underneath flanges of adjacent collars to hold the worm in place. One or both of the worm bodies are keyed or otherwise fastened to the shaft for driving. Relatively slight longitudinal movement of one or both adjacent collars will release the parts of the worm body for repair and/or replacement without disassembling the entire worm-collar-shaft assembly.
