Specification of John Hawksley's 1797 English patent for improvements to wool and fibre combing machinery, as printed in the Repertory of Arts and Manufactures. It describes a circular revolving comb-pot (stove) for heating combs, a lapper or layer-on for feeding wool onto the combs, and holsters for holding the combs while the wool is drawn off. It builds on his earlier 1793 combing machine patent. Two plates of engraved machinery diagrams accompany the text.
