Encyclopedia article on mill-work from Rees's Cyclopedia, describing the common mechanical parts of mills: cog-wheels (spur, face, bevel/mitre wheels), pinions and trundles, wooden and cast-iron wheel construction, fixing wheels on shafts, bearings and friction rollers, shaft couplings and universal joints, and governors for regulating speed. It includes three engraved plates of gear, bearing, and shaft diagrams. The article concerns general mill machinery rather than textile processes, though it is relevant to the mechanics of textile mills.
