De Olifant, Burdaard Each revolution of the screw lifts of water. The drive to the Archimedes' screw that pumps water into the polder is from a 38-cog gear wheel meshing with the "great spur wheel". This drives a 25 stave gear wheel which drives a "wallower" (30 cogs). The "wallower" drives a gear wheel with 31 cogs. This drives a cast iron gear wheel with 48 teeth. This drives the Archimedes' screw via a cast iron gear wheel with 60 cogs on the axle of the Archimedes' screw. This Archimedes' screw has an axle diameter of and is diameter overall. It is inclined
SS Archimedes overhaul. Her engines and machinery were removed on an unspecified date at Sunderland, after which she continued in service as a sailing ship. In 1852, her sails and rigging were renewed, but she disappeared from the Register again a year or two later. She reportedly ended her career in the 1850s, in service between Chile and Australia. Although the adoption of the screw propeller was an historical inevitability given the work of John Ericsson and others, "Archimedes" considerably hastened acceptance of the technology. The Dover trials, carried out in April–May 1840, persuaded the Royal Navy to build a 900-ton steam
