Scientific American, Vol. 5, No. 8 (1861)
Scientific American volume 5, number 8, a weekly American technical newspaper from 1861 aimed at inventors, mechanics and manufacturers, printed in New York and carrying engraved drawings of patented machines and devices. The pictures are precise line engravings with lettered reference figures, showing a clamping fixture, a large lathe-like machine tool, a measuring gauge and a lamp or stove mechanism with labelled parts, useful to a designer for their clean mechanical diagram style.
