US design patent D19,208, granted July 16, 1889 to John S. Lamond and Colin T. Robertson of Paterson, New Jersey, for a carpet design. The drawing shows a square pattern of woven-looking blocks with lettered parts. The specification describes two alternating groups of bars: group a has three long bars with shorter outer bars, and group b has two transverse long bars with a short outer bar. It claims the design as shown and gives no weaving structure or draft.
