Kinks for wool carders and spinners
A 1907 trade handbook published in Boston for wool carders and spinners in New England mills, collecting shop-floor tips on carding and spinning machinery. Line engravings alternate between machine parts and gear-train schematics with directional arrows and advertisers' trademark seals — a ram's head roundel, a stencilled shipping barrel, a maker's nameplate — giving designers usable industrial diagrams and period trade-mark lettering.
