Metal Airplane Construction
A 1926 technical report on metal airplane construction, issued through the NASA Technical Reports Server from a aeronautics archive and aimed at engineers and aircraft designers. Its pictures are plain line drawings of structural parts: a girder web with cut-out panels, a three-way tubular joint with rivet holes, a truss-framed fuselage, a multi-spar wing section, and a tube-to-socket connection in section. A designer could draw on their clean, schematic linework for industrial diagram or technical illustration styles.
