US Patent 1,764,576, granted 17 June 1930 to Walter Nicolet of Leipzig, Germany, for a loom that weaves two fabrics' worth of shedding at once using two sets of warp threads and guide combs. A single rigid weft bobbin supplies weft that is entered into a closed front shed and an open rear shed as a hairpin loop, then cut off, which produces a proper selvedge. The scan has three sheets of drawings (Figs. 1-6 showing consecutive loom positions), the specification, and 17 claims covering the method and the loom.
