Scientific American, Vol. 47, No. 4 (July 1882)
An issue of the weekly American popular-science and invention paper Scientific American, published by Munn & Co. in New York in July 1882 for inventors, manufacturers and general readers following new patents. The plates are wood engravings of machinery and instruments — three-quarter views of engines and presses on hatched floors, cutaway plan sections, and a wall-mounted telephone with lettered nameplate — usable as mechanical silhouettes, texture from ruled shading, and small labelled hardware details.
