Journal of the Association of Engineering Societies
A periodical of engineering papers issued in 1881 by the Association of Engineering Societies, a United States professional body, published in New York for practising engineers and their colleagues. Its plates are mechanical and technical line drawings: a graphical construction with radiating curves, cast steel pin bearings shown in plan and section, a floor layout of a room with two cylindrical units, and a sectioned pump or valve with an exploded bottom view. A designer could take their clean hairline drawing style, labelled dimension lines and tidy hatching as models for technical diagrams.
