The theory and practice of the art of weaving : by hand and power, with calculations and tables, for the use of those connected with the trade
A technical manual on weaving by hand and power, written by John Watson, a manufacturer, and published in Philadelphia in 1869 for people working in the textile trade. Its pictures are plain line diagrams: rows of shaded blocks and bars that read as weave drafts or pattern threading charts, plus one mechanical drawing of a loom mechanism with a driving weight, lever and labelled parts, useful to a designer looking for simple geometric block patterns or schematic machine linework.
