Reprint of the 1793 patent specification of Henry Wright and John Hawksley of Arnold, Nottinghamshire, for machinery to comb and prepare wool, cotton, silk, flax, hemp and mohair for spinning. The text describes the machines part by part, giving gear and cog counts, the comb-wheel and combing cylinder, a feeding frame with linen cloths and rollers, a brush for removing noils, and a second machine with a straight range of combs. Two engraved plates (XIII and XIV) illustrate the figures.
