James Lowe (1796–1866) was the English inventor of a screw propeller. LifeLowe was apprenticed on 2 November 1813 to Edward Shorter, a master mechanic and Freeman of the City of London, who had in 1800 taken out a patent for propelling vessels, which he had named "the perpetual sculling machine". In 1816 Lowe ran away and joined a whaling ship, the {{ship||Amelia Wilson|1809 ship|2}}, but after three voyages returned to his master. Later Lowe went into business as mechanist and a smoke-jack maker, and experimented on screw-propellers for ships. On 24 March 1838 he took out a patent, No. 7599, for "improvements in propelling vessels" by means of one or more curved blades, set or fixed on a revolving shaft below the water-line of the vessel. His propeller was first practically used in the steamship Wizard in 1838, and then in Rattler and Phœnix. On 16 December 1844 Lowe brought an action in the Court of Queen's Bench against Penn & Co., engineers at Greenwich, for infringement of the patent. The evidence was contradictory, but it was shown that Lowe, although not the original inventor of propellers, was the inventor of a combination nor before applied to the propulsion of vessels. This combination consisted of three parts:
The jury gave a verdict in his favour. On 19 August 1852 he took out another patent, No. 14263, for his propeller. Lowe spent his wife's fortune on his experiments, reduced himself to poverty, and never succeeded in obtaining any compensation for the use of his invention. He died on 12 October 1866 when a wagon ran him over in the Blackfriars Road, London, killing him. FamilyLowe married, on 30 May 1825, the eldest daughter of Mr. Barnes of Ewell, Surrey. She died in 1872. HenriettaTheir daughter, Henrietta, who in July 1855 married Frederick Vansittart, of the 14th Light Dragoons, continued her father's experiments. As Henrietta Vansittart she took out a patent, No. 2877, on 18 September 1868, for a further improvement, which she called the "Lowe-Vansittart propeller". This was fitted to many government ships, and was found to be a valuable invention. It was also used on the SS Lusitania.[1] References1. ^{{cite web|last1=Howes|first1=Anton|title=11 Forgotten Women who Invented the British Industrial Revolution|url=https://medium.com/@antonhowes/11-forgotten-women-who-invented-the-british-industrial-revolution-ea34e185f187|website=Medium|accessdate=11 May 2017}}
