US Patent 1,942,152 (granted Jan. 2, 1934) by Oskar Sauer of Philadelphia describes a method of weaving fabrics with a three-dimensional surface, aimed mainly at woven lace hosiery blanks. Fullness at the heel is formed on a Levers lace machine by selectively suppressing warp shifting and interrupting take-up, with warp threads drawn from individual beams. The text covers the machine's operation, blanks with selvages separated by lacer threads, an alternative on an ordinary loom with partial shuttle throws, and four method claims. It includes two sheets of drawings of the stocking blank, mesh fabric and machine details.
