US Patent No. 714,909, granted December 2, 1902 to George F. Hutchins and Eppa H. Ryon of Worcester, Massachusetts, assignors to Crompton & Knowles Loom Works. It describes automatic cross-weave (leno-type) mechanism for power looms, using forked needles in front of the reed to move selected warp threads sideways over adjacent threads, so effects formerly woven on hand looms can be made on power looms. The document has six sheets of patent drawings (Figs. 1-19) followed by the specification, with dobby and harness-jack modifications, warp-easing details, and numbered claims.
