William Church (circa 1778–1863) was an American inventor who patented a typesetting machine in 1822, generally considered the first. While living in Boston, he patented the Church Typesetting Machine in England, consisting of a keyboard on which each key released a piece of type of the corresponding letter stored in channels in a magazine.〔Huss, Richard E. (1976). ''Dr. Church's "Hoax": An Assessment of Dr. William Church's Typographical Inventions in which is enunciated Church's Law.'' Graphic Crafts, Inc. ISBN 1-299-79852-7〕 At some time after this, he moved to Bordesley Green near Birmingham in England, presumably to promote his patent. He was a prolific inventor, taking out numerous patents for methods of button making, nail making, metal working, smelting iron, spinning and other branches of engineering. In 1824 he patented a printing machine which positioned the paper sheets more accurately. He turned his attention to steam engines, with a patent in 1829 for marine engines and associated equipment, and another in 1830 for an improved furnace. He patented his first steam carriage in 1832. This does not appear to have been built, but a further patent in 1835 led to the formation of the London and Birmingham Steam Carriage Company. The company prospectus describes their vehicle of 60 hp, capable of carrying a load of 15 tons at a rate of 15 miles an hour. The Science Museum has an engraving by Josiah Allen 〔(Science and Society Picture Library - Search )〕 which shows it as a large three-wheeled vehicle with passenger compartments front and rear similar to conventional stagecoach bodies, with seating on top, and the driver mounted high at the front operating a tiller for steering. The central part contained the mechanism. It would seem however that this was not the vehicle which was eventually built. Although some accounts suggest that it operated on a daily basis between London and Birmingham, Prosser 〔Prosser, R.B. (1881) ''Birmingham Inventors and Inventions'' Private publication, reprinted 1970 Wakefield: S.R.Publishers.〕 suggests that it never in fact completed a journey, and the company was wound up. Although a number of steam powered coaches were tried between 1820 and 1840, they were extremely unpopular. With various impediments from excessive tolls on the turnpikes to virtual sabotage, prospective passengers were unnerved by being so close to the boiler. In the end, the railway, with its smooth running track and increasing speed, put an end to them. In 1838 he built a steam locomotive which had various names but was most notorious as the "Surprise" which was tried unsuccessfully in the early days of the Lickey Incline in England. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「William Church (inventor)」の詳細全文を読む スポンサード リンク
