August von Borries

August Friedrich Wilhelm von Borries ( born January 27, 1852 in Lower Becksen, Minden in Westphalia, † February 14, 1906 in Meran ) was a German engineer who dealt primarily with developments in locomotive. He came from the Westphalian- Lower Saxon noble family letter Borries.

Von Borries was 1870-1873 Student at the Royal Commercial Institute in Berlin -Charlottenburg. After working at the Bergisch- Märkischen railway company he joined in 1875 in the service of the Directorate of Hanover Prussian State Railways ( KPEV ) a. After office as director of the Workshop in Lingen, he was in 1881 appointed head of mechanical engineering design offices. 1885 is transferred from Borries the management of the workshop in Leinhausen in a machine inspector property. 1888 Finally, he was promoted to head of the mechanical engineering offices of the railway department Hanover. First Mechanical engineer in Prussia in 1894 finally appointed by Borries the government and building officer. During his tenure at the KPEV he acquired special merits to the introduction of the fuel- saving composite engine in Dampflokomotivbau as the 1880 made ​​construction of the first two Prussian composite locomotives by Schichau in Elbing ( Prussian Omnibus locomotive Class T 0, BB wheel 1 A n2vt ).

Von Borries developed named after him single-axis of the compound locomotive, in contrast to the two-axle according to the type de Glehn act lying on a transverse plane high and low pressure cylinders on a common axis with the goiter. A well-known and preserved example of this engine assembly, for example, the Bavarian S 2 / sixth Further developed by Borries required in composite locomotives at least manually operated Anfahrvorrichtungen, which for the purpose of safe startup of the machine by supplying steam directly to the low-pressure cylinders, the composite action can be lifted further. He also created self-acting Anfahrvorrichtungen ( shuttle valves ). These were not only in Germany but also in other countries often use. In 1902 he finished his work at the Prussian State Railways and was appointed professor of railway engineering at the Technische Hochschule Charlottenburg converted former Commercial Institute at ..

Furthermore, gave von Borries among others a textbook on the locomotive out.
