A practical treatise on dyeing, and callicoe printing: exhibiting the processes in the French, German, English, and American practice of fixing colours on woollen, cotton, silk, and linen
A practical treatise on dyeing and calico printing, compiled by Thomas Cooper and published in Philadelphia in 1815 for dyers and manufacturers working in woollen, cotton, silk and linen. The plate shows mechanical apparatus: a wooden-framed stand holding a round vat with a vertical rod and crank linkage, plus a second vat with a rotating arm and a pendant handle. A designer might take from it the spare, rule-straight line work of early technical engraving and its schematic approach to showing machinery.
