Scientific American, Vol. 42, No. 8 (1880)
Scientific American volume 42, number 8, from 1880, is a weekly American periodical of technology and invention news aimed at engineers, inventors and general readers. Its wood engravings show machines and devices with clear outlines and labelled parts, including a crossed-rod electric gun, a factory with workshop interiors, a three-wheeled steam carriage and a ship's steering gear, giving designers plain, legible mechanical forms to borrow for diagrams and industrial motifs.
