An American manual roller mower first introduced in 1870 by the American firm Hills of Hartford, Connecticut, USA, the Archimedean had a cutting cylinder working on the principle of the Archimedean screw. Early machines had skids rather than a front roller, but these were soon discarded. The "Archimedean" was sold by many ironmongers up and down the country, one of the UK Agents in 1884 being John G Rollins of London Bridge. They appear also to have been made under licence in Great Britain, with machines which included the "New Archimedean" (see Cottiss). See also "Junior Archimedean".
