Scientific American, Vol. 7, No. 52 (1852)
This is a page of the weekly Scientific American from 1852, printed in New York for American mechanics, inventors and manufacturers, and it carries technical notices and patent-style engravings of machinery. The pictures are plain line engravings with lettered reference points, such as a brick machine elevation, a sectional roller press, a pump cylinder and a row of clay moulds, and a designer could take their clean diagrammatic structure and labelled schematic style.
