Scientific American, Vol. 24, No. 3 (1871)
Scientific American volume 24, number 3 from 1871, a weekly American periodical of technology and invention aimed at general readers, mechanics and inventors. Its pages mix text columns with engraved diagrams of machines and apparatus, and these sampled pictures show a perpetual-motion-style wheel with weights, a magnetic or rotating mechanism in a box, and a cotton press set in a shed with workers. Designers can take from them the dense, precise linework of nineteenth-century technical engraving and the layout of text set beside full-width plates.
