Arkwright - Spinning and Roving Cotton, US Patent 36X of 1791
This is a rotated scan of an 1791 United States patent drawing by Richard Arkwright for cotton spinning and roving machinery, a technical document filed for an inventor rather than a published book. The sheet is a mechanical plan with a handwritten title running down the left edge, and a designer might take its dense, schematic linework and hand lettering as a model for industrial diagram style.
