{Archimedean screw}, or {Archimedes' screw}, an instrument, said to have been invented by Archimedes, for raising water, formed by winding a flexible tube round a cylinder in the form of a screw. When the screw is placed in an inclined position, and the lower end immersed in water, by causing the screw to revolve, the water is raised to the upper end. --Francis. [1913 Webster] ||
