Text of the 1796 patent specification of Richard Varley of Bolton-in-the-Moors, Lancashire, for machinery to card, rove, and spin cotton, wool, and silk. It describes a main carding cylinder with two doffing cylinders covered in striped leather cards, doffing knives, a feeder, and drawing rollers. It also covers the spindles, flyers, lifters, bobbins and springs of the roving and spinning frame. A plate with five figures of the machinery accompanies the text.
