Archimedes' screw was turned by hand, and could also be used to transfer water from a low-lying body of water into irrigation canals. [10] [11] Archimedes never claimed credit for its invention, but it was attributed to him 200 years later by Diodorus, who believed that Archimedes invented the screw pump in Egypt. [1]
Sir Francis Pettit Smith (9 February 1808 – 12 February 1874) was an English inventor and, along with John Ericsson, one of the inventors of the screw propeller.He was also the driving force behind the construction of the world's first screw-propelled steamship, SS Archimedes.
The date of birth is based on a statement by the Byzantine Greek scholar John Tzetzes that Archimedes lived for 75 years before his death in 212 BC. [9] Plutarch wrote in his Parallel Lives that Archimedes was related to King Hiero II , the ruler of Syracuse, although Cicero suggests he was of humble origin.
By at least the 3rd century BC: Archimedes' screw, one of the earliest hydraulic machines, was first used in the Nile river for irrigation purposes in Ancient Egypt [258] Early 3rd century BC: Canal lock in Canal of the Pharaohs under Ptolemy II (283–246 BC) in Hellenistic Egypt [ 259 ] [ 260 ] [ 261 ]
The first records of a screw pump, also known as a water screw or Archimedes' screw, dates back to Ancient Egypt before the 3rd century BC. [ 19 ] [ 20 ] The Egyptian screw, used to lift water from the Nile , was composed of tubes wound around a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.

A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes.
The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water. [1] They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer ...
