Text of George Jeffreys' patent (dated March 18, 1791) for a resist method of dyeing woollen cloths and stuffs in stripes, figures and patterns. A hot composition of powdered tobacco-pipe clay and tallow is applied through perforated brass grates to keep chosen areas from taking dye, and is later removed with fuller's earth. The text describes the brass grate, sliding frame and a machine for striping whole lengths of cloth, plus a frame for holding the cloth in the dye kettle. Two engraved plates (XVI and XVII) illustrate the apparatus.
