US Patent No. 1,368,215, granted to Frank H. Stewart of Elkins Park, Pennsylvania, on Feb. 8, 1921, for a woven fabric with reversely diagonal warps and transverse wefts. The fabric behaves like bias-cut cloth but has woven selvages and does not fray at the edges. The specification describes a continuous weft thread running to and fro, optional selvage warp and loop-locking threads, and a heddle arrangement on sliding bars and semicircular guides that moves the warps diagonally. Two sheets of drawings show the fabric structure (Fig. 1) and four successive heddle positions (Figs. 2-5), followed by three claims.
