Scientific American, Vol. 46, No. 14 (April 1882)
A weekly issue of Scientific American, published in New York in April 1882 for inventors, engineers, and mechanically curious general readers. Wood engravings show machinery in catalogue-style elevations and cutaway sections — valves, a vertical steam engine on a cast plinth, a multi-head planing machine — with dense line hatching that designers can lift as isolated technical silhouettes or texture.
