Scientific American, Vol. 40, No. 9 (1879)
Scientific American, volume 40, number 9, is a weekly American periodical of 1879 published in New York for an general readership of inventors, engineers and mechanics. Its pages mix wood-engraved machine drawings, patent-style figures of mechanisms, and small trade advertisements for tools and machinery. Designers can take from it the precise, labelled line style of nineteenth-century technical diagrams, with clean hatching and figure numbers that suit schematic or infographic work.
