Brass, Steel and Wrought Iron Wheel Cutting Engine

The free-standing crank-driven engine is on faceted wrought iron legs supporting the iron frame, with 12 1/2 in. brass dividing plate marked T. Green Divisit, having twenty-eight rows of numbered divisions. A large end-mounted screw is turned with a wrought iron handle to move the cutting apparatus laterally. A hinged box contains various cutters.

This engine is very similar to several wheel cutting engines made by Wyke, Green, or Wyke & Green, all of which were based on the engraving of an engine design in Emerson's Principles of Mechanics (1758). It is unusual to find an engine made only by Thomas Green, since most of his work was in partnership with Wyke.
