Scientific American, Vol. 33, No. 13 (1875)
Scientific American volume 33, number 13, from 1875, is a weekly American periodical of science and invention aimed at engineers, inventors and general technical readers. Its pages carry wood-engraved mechanical drawings of engines, pumps, rescue apparatus and electrical diagrams, with cross-sections and multiple views of each device. A designer could take from them the clean line-and-hatching conventions of nineteenth-century technical drawing, with exploded or sectioned views for showing how machinery fits together.
