Scientific American, Vol. 52, No. 9 (February 1885)
An issue of the weekly Scientific American, published by Munn & Co. in New York in February 1885 for inventors, engineers, and patent-minded general readers. The engravings are small wood-cut machine portraits — a flywheel pump, a multi-head planing mill, a geared tool head, a battery-powered track car — rendered in dense hatching on blank grounds, ready to lift as isolated silhouettes or repeating technical motifs.
