Edmund Cartwright describes his patented machine for combing wool mechanically, in place of hand-combing. He discusses the economic importance of the invention, the opposition from wool-combers and the rejected parliamentary bill, his three patents of 1790 and 1792, and the labor and cost savings. The article ends with a specification of the machine's parts (crank lasher, circular clearing comb, comb-table with drawing rollers), keyed to an engraved plate.
