US Patent 1,581,936, granted April 20, 1926 to Kurt Lehmann of New York, assignor to So-Me-On Corporation, for an embroidery pattern and the method of making it. It describes rows of straight stitches laid as nested, overlapping angles that look like chain stitch but cover the base fabric more completely, and that can be produced on Schiffli embroidery machines. The patent includes drawings of a parrot figure, an enlarged stitch pattern, and a cartoon diagram of the stitching sequence, plus eight claims.
