A dictionary entry on the scutcher, a machine that separates and cleans cotton fibers after the opening machine. It describes in detail how the cotton-scutcher works, from feed-cloth and nipping-rollers to batting-arm, fans and dust box, and gives its output. It also covers the scutcher's use for dressing flax and for beating floss and refuse silk before carding. A cross-sectional engraving of the cotton scutcher is included.
