Kinks for wool carders and spinners
A 1907 Boston trade manual of practical tips for wool carders and spinners, aimed at mill hands and overseers in the American woolen industry. Line engravings show carding machinery in elevation and section, gear trains laid out as arcs of toothed wheels, and a stencilled soap barrel advertisement, offering designers clean mechanical diagrams, repeating cog and card-clothing textures, and period trade lettering.
