Scientific American, Vol. 32, No. 12 (1875)
A weekly American science and invention periodical from 1875, edited for a general readership of inventors, mechanics and tradespeople. Its pages carry precise wood and metal engravings of machines, tools and devices, such as a pipe joint, a draft tongue for reapers and a surveying compass, with brief patent notices and descriptive text. Designers can take its crisp, labelled line diagrams and clean mechanical layouts as models for technical illustration.
