Scientific American, Vol. 24, No. 18 (1871)
Scientific American volume 24, number 18, from 1871, is a weekly American magazine of science and mechanical invention, written for engineers, inventors and manufacturers. The pictures are wood-engraved line drawings of machines: a vertical steam apparatus, a power press, a steam excavator at work on a cutting, and a horse-drawn dumping cart. A designer could take from them the dense, labelled technical style of Victorian machine drawing, with clear outlines, hatched shading and small annotated parts.
