Excerpt from A Compendious History of the Cotton-Manufacture: With a Disproval of the Claim of Sir Richard Arkwright to the Invention of Its Ingenious Machinery In 1772, James Hargrave, the improver of the Jenny, invented the Crank and Comb, a curious and most ingenious contrivance for taking the cotton off the cylinder. A thin plate of steel, toothed at the edge like a tennant saw, is worked in a perpendicular direction by a crank, and striking at short intervals against the cylinder, shaves off the cotton in fleeces or cardings. See plate 10, figs. 2 and 3. The cards were nailed on both cylinders in longitudinal stripes, each stripe of card being placed parallel to the axis of the cylinder. These stripes were five or six inches broad, and from twelve to twenty inches long, according to the length of the cylinder. In the circumference of the second cylinder there were eight or ten stripes, and as the spaces between these stripes did not act upon the carded cotton, the fleece was broken off at each interstice; these broken fleeces were by the Crank and Comb, divided into four or more cardings, each carding being about an inch in diameter and twelve or twenty inches long.
