Machines et inventions approuvées par l'Academie royale des sciences, depuis son établissement jusqu'à present : avec leur description : dessinées & publiées du consentement de l'Academie
A French folio of machine plates from 1735, compiled by Jean-Gaffin Gallon and published in Paris with the approval of the Académie royale des sciences to describe approved inventions. The four plates show mechanical drawings with plan and elevation views of a plank-rolling machine, its toothed wheels and gears, and a clockwork quadrature mechanism with an eccentric cam. Designers can draw on the precise engineering linework, the labelled exploded parts, and the dense gear geometry for technical diagram motifs.
