Scientific American, Vol. 52, No. 2 (1885)
Scientific American volume 52 number 2 from 1885 is a weekly American periodical of mechanical and technical news, written for inventors, engineers and general readers. The pictures are black-and-white engraved line drawings of machines and devices, each labelled with a caption, including a yeast-pressing machine, an early flying machine with a propeller, a numbered safety valve cutaway, and a hand pump beside a cistern cut-off, useful to designers wanting precise Victorian mechanical detail.
