Scientific American, Vol. 55, No. 2 (1886)
Scientific American volume 55, issue 2, published in New York in 1886, is a weekly technical periodical written for engineers, inventors and general readers of mechanical and scientific news. Its pictures are wood-engraved mechanical drawings of typewriter parts, steam engines, a valve and float assembly, and mica forms, giving a designer a dense, precise vocabulary of line-drawn machinery with clear labelling and hatching.
