Weaving : instruction paper
This 1903 instruction paper from the American School in Chicago, written by H. William Nelson, teaches weaving mechanics to students of the trade through pages of technical line drawings. The four pictures are mechanical diagrams of loom parts: linkages, gears, cams, and lever arms, each labelled with capital letters for reference. A designer could draw on their crisp hairline geometry and lettered callouts for schematic or technical illustration work.
