Joseph Farcot

Jean Joseph Léon Farcot (23 June 1824 – 19 March 1908) was a French engineer and industrialist whose factories employed up to 700 workers.

[3] In 1846 Marie-Joseph Farcot transferred his factory close to the docks and railway station in Saint-Ouen on the Seine.

[4] In 1867 the Maison Farcot received the Grand Prix pour mérite hors ligne at the International Exposition of 1867 in Paris.

[5] They won a gold medal for their horizontal steam engines in the class of motors, generators and mechanical devices.

[6] The report of the jury noted that the Farcots had installed two 100 horsepower Woolf pumps which took water from the Seine at the quai d'Austerlitz in Paris and delivered it along a line of 5 to 6 kilometres (3.1 to 3.7 mi) to the reservoirs at Ménilmontant, 50 to 60 metres (160 to 200 ft) higher up.

[9] Engineers designed various types of hydraulic or pneumatic pump regulator to overcome the limitations of Watt's governor.

[13] Farcot's automatic variable expansion-gear, an attachment to a Corliss steam engine, was exhibited at the Exposition Universelle of 1878 in Paris.

[14] Joseph Farcot may deserve as much credit as John McFarlane Gray for inventing steering engines that use feedback.

[13] In 1873 he published a book Le servo-moteur ou moteur asservi that described the different steam steering devices that Farcot and Son had developed.
