De l'Utilité du Belier Hydraulique.
FIRST SEPARATE EDITION. The invention of the hydraulic ram.Joseph de Montgolfier, who with his brother was a pioneer of human flight, "subsequently made several inventions, the most important of which was the hydraulic ram, a simple device for raising water, which was widely adopted. The machine consisted of two valves in an iron box (the 'ram's head') which were automatically operated by the changing pressure of water flowing into it" (DSB).An extremely simple device, it has only two moving parts and is powered by the water itself, thus allowing itself to pump water independently of any adjustment or maintenance for as long as the supply lasts.Montgolfier's invention was described in several papers; the present is an offprint from the Bulletin de la Société d'encouragement pour l'industrie nationale, 1805. It is difficult to say which is the first separate appearance; the first published paper listed by the DSB, Note sur le belier hydraulique, was published in 1802-3 but the separate publication did not appear until 1806. The other separate publications listed in the catalogue of the BnF are undated.8vo, 1 leaf, 18 pages, 1 folded engraved plate by N.L. Rousseau. Later plain paper wrapper.
