Arturo Caprotti
Arturo Caprotti ( born March 22, 1881 in Moscazzano, † February 10, 1938 in Milan ) was an Italian engineer.
Life
Arturo was son of Giuseppe Caprotti, a municipal secretary in Moscazzano in the province of Cremona, and Albina Moretti. In addition to the two-year pre-training for his engineering studies in Pavia, he attended the prestigious Collegio Ghislieri. However, a degree in industrial engineering, he made in 1905 in Turin. After that he began in Florence to work in the Fabbrica di Automobili Florentia. He was interested in the thermodynamics and thermal engineering as well as the mechanics.
In 1917 he married Iole Martinelli, a banker's daughter. According to other sources, he married them in 1910 and it was built in 1912 on the land his father in law, according to his plans, a small two-story villa. Villino Jole (now scrub ) is located next to Villa Martinelli in Via Paganini # 76 in Lucca. Occasionally, devoted Caprotti still other architectural projects, such as 1913, the Villa Giomi.
1958 was fixed on the occasion of his 20th death anniversary of the municipality Moscazzano a plaque at his birthplace. In addition, there are in Rome and named streets after him.
Inventions
In January 1921, the first steam locomotive (Consolidation No. 740 324 ) was taken with the he designed Caprotti control, valve control in the Ferrovie dello Stato in its regular operation. The invention has been accompanied by reports in the international press. As a result, they built a control into existing locomotives. Since 1926, drove the net the London, Midland and Scottish Railway locomotives of William Beardmore and Company with this control, in the United States built Baldwin Locomotive Works in the control locomotives. In Germany and Austria the control, however, was used tentatively. Later, the control also in the railway network of France, India, Egypt and Romania, and other countries was used. Furthermore, she was also in steam vessels operating on Lake Como, in the lagoon of Venice, as well as built- in two English vessels fabrication.
Comparison tests in Germany in the presence Caprottis with a conventional, controlled by piston valve Prussian P 8 and a refitted Caprotti valve control P 8 were less favorable steam and coal consumption values of the locomotive with valve control compared those with piston valve control, moreover, the Caprotti control was more susceptible to interference.
The London Institution of Locomotive Engineers awarded him for his invention of a gold medal.
