Scientific American, Vol. 42, No. 13 (1880)
A weekly American science and technology periodical from 1880, published in New York for engineers, mechanics and inventors. Its pages carry wood-engraved drawings of patented machines and mechanical devices, with the figures keyed to lettered parts. The engravings are crisp line work in dense black and white, showing machine frames, pulleys, belts and hand tools, useful to a designer studying nineteenth-century mechanical form and diagrammatic labelling.
