Scientific American, Vol. 52, No. 16 (April 1885)
A weekly issue of Scientific American, published by Munn & Co. in New York in April 1885 for inventors, engineers and mechanically minded general readers, reporting new patents and industrial machinery. The wood engravings show engines, planers, presses and pipe fittings in three-quarter view on hatched floors, with lettered cutaway details and small operator figures for scale, giving designers reusable machine silhouettes, gear and flywheel forms, and tonal hatching textures.
