Archimedes' screw

(ˌɑːkɪˈmiːdɪən; -mɪˈdiːən) or

Archimedean screw

n (Mechanical Engineering) an ancient type of water-lifting device making use of a spiral passage in an inclined cylinder. The water is raised when the spiral is rotated

Ar′chime′des' screw′

n. a device consisting essentially of a spiral passage within an inclined cylinder for raising water to a height when rotated. [1860–65]

Archimedes' screw

Archimedes' screw,

a simple mechanical device believed to have been invented by Archimedes in the 3d cent. B.C. It consists of a cylinder inside of which a continuous screw, extending the length of the cylinder, forms a spiral chamber. By placing the lower end in water and revolving the screw, water is raised to the top. The principle is applied in machines used for drainage and irrigation, and also in some types of high-speed tools. It can also be applied for handling light, loose materials such as grain, sand, and ashes.

Archimedes' screw

[¦är·kə¦mēd‚ēz ′skrü] (mechanical engineering) A device for raising water by means of a rotating broad-threaded screw or spirally bent tube within an inclined hollow cylinder.
