US Patent 1,775,144, granted 9 September 1930 to Harold F. Sherman of Northboro, Massachusetts, for a dense single-ply woven fabric and the method of weaving it. Warps are woven in pairs, one lying over the other, with straight wefts in a median plane. Alternate 'key' wefts are bound by warp bights and intervening wefts hold the bights tight. The fabric repeats on four ends and four picks and is intended as a broadcloth-like material for collars and cuffs. The patent has two sheets of drawings (Figs. 1-7, including a weave diagram and drawing-in draft), a description, and 15 claims.
