US Patent No. 1,786,569, granted to Charles F. Lee of Philadelphia on December 30, 1930, for a combined woven and knitted fabric. Certain weft threads are interlooped to form knitted sections between woven sections, with no extra yarns added. The unlooped weft threads and bunched warp threads resist stretching in both directions. The patent has drawings of the fabric in plan and section, a short specification, and six claims.
