Scientific American, volume 31, number 2, published in New York in 1874, is a weekly technical periodical for general readers interested in mechanics, invention and science. Its pictures are black-and-white engravings of machines and apparatus, with lettered reference figures, cutaway sections and exploded parts that suggest clean diagrammatic line work a designer could borrow for technical layouts.
