Joseph-Philibert Desblanc
Joseph-Philibert Desblanc (* 1760 in Mâcon, Département Saône-et-Loire; † 27. November 1820 in Trévoux, Département Ain) war ein französischer Ingenieur, Erfinder und Uhrmacher. Er war der erste, der in Frankreich ein Patent auf ein Dampfschiff anmeldete.
Leben
Desblanc war der Sohn von Claude Desblanc und Marie Saurien.[1] 1782 arbeitete er für die Gebrüder Jean am Raddampfer Pyroscaphe des Erfinders Claude François Jouffroy d’Abbans. Im selben Jahr entwarf er ein eigenes Dampfschiff, bei dem die Dampfmaschine statt eines Schaufelrades eine Kette mit Schaufeln antrieb und das Schiff so fortbewegte. Das Schiff hatte eine Länge von 18,90 Meter, eine Breite von 4,90 Meter und einen Tiefgang von 0,61 Metern. Es wurde durch eine horizontale, doppelt wirksame Dampfmaschine angetrieben. Der Kolben der Dampfmaschine hatte einen Durchmesser von 0,53 Metern, dieser führte einen Hub von 1,37 Metern aus. Das Schiff soll auf der Saône getestet worden sein, wurde jedoch aufgegeben, da ein Konstruktionsfehler in der Kette bestand.
Im Jahr 1802 erhielt Desblanc ein Patent auf seine Erfindung und kam so dem Amerikaner Robert Fulton zuvor. Claude François Jouffroy d’Abbans ging gegen das Patent vor, wurde jedoch nicht gehört.[2]

th sail-power. It is as a sailing rather than as a steam vessel that we must for ever regard the Savannah^ and on her return to America her engines were taken out of her and she became a sailing ship again. England, too, showed she could build a bigger sea-going steamship when, two years after the visit of the Savannah the celebrated James Watt was launched at Glasgow. With a tonnage of 420 and two engines and paddle-wheels, she was rigged not like the Savannah but as a three-masted fore-and-aft schooner with jib, staysail, and jib-topsail. Her square stern, her band of white and black ports, her bow with figurehead,are all in keeping with the naval architecture of the time.With a high smoke-jack placed between the foremast and the main, with her paddles now covered up on the top by boxes—unlike the Savannah^ whose paddle-wheels had been left open—the James Watt represents a type of sea-going steamer which remained for many years, with but minor adaptations externally, as the prevailing ex- 120

In spite of the chilly reception with which steam had been received by most people in any way connected with ships and the sea, there were the most sure and certain signs that the revolutionary innovation had come to stay. By 1825 a little auxiliary steamship of only 176 tons, named the Falcon had reached Calcutta, going round Cape Horn, and in the same year the Enterprise a bigger ship of 470 tons, had made the same voyage, and during 103 out of 113 days of her journey was propelled not by sails but under steam-power. This proved still more the capability of the steamship, though it was to be many years before sails ceased to be relied on, at least for emergency if not for ordinary propulsion. Although the su
