Scientific American, Vol. 44, No. 11 (1881)
This is a weekly American periodical of 1881 aimed at general readers interested in invention, industry and science, filled with engraved diagrams of machines and apparatus. The pictures show precise line-engraved mechanisms: a hand-held instrument with a wooden grip, a vertical steam engine on a cast-iron base, a man standing beside a large mounted telescope, and a starch-preparation vessel with pipes and valves. A designer might draw on their clean hatched linework, their exact labelled parts and their Victorian technical clarity.
