Scientific American, Vol. 3, No. 33 (May 1848)
An issue of the weekly Scientific American (vol. 3, no. 33, May 1848), published in New York for inventors, mechanics and readers following new patents. The wood engravings are small working diagrams: cylinders, gear trains and warp frames on trestle legs, parts keyed with letters, plus a vignette of a woman at a loom and a clerk writing among stacked ledgers and wheels, useful as compact line-art machine parts and technical lettering.
