Machines et inventions approuvées par l'Académie Royale des Sciences depuis son établissement jusqu'à présent
This is a 1720 Paris collection of machines and inventions approved by the Académie Royale des Sciences, compiled by the Académie des Sciences and held by Heidelberg University Library, recording mechanical designs for engineers and craftsmen. The plates show engraved machine diagrams with labelled parts, gears, wheels and frames, plus a decorative ornamental header; a designer could draw on their clean line hatching and precise mechanical structure.
