Pratt & Whitney Measurement Systems is an American multinational corporation that specializes in producing high-precision measuring instruments and systems. ==History== The Pratt & Whitney Company was founded in 1860 by Francis A. Pratt and Amos Whitney, with headquarters in Hartford, Connecticut. The company manufactured machine tools, tools for the makers of sewing machines, and gun-making machinery for use by the Union Army during the American Civil War.〔(Francis Pratt ), Britannica.com〕〔(Amos Whitney ), Britannica.com〕 In 1925, Frederick Rentschler approached Pratt & Whitney for funding and a location to build his new aircraft engine.〔(Engineering Success: Pratt & Whitney Aircraft ), Bayla Singer〕 Pratt & Whitney loaned him $250,000, the use of the Pratt & Whitney name, and space in their building. This was the beginning of the Pratt & Whitney Aircraft Company, which evolved into today's widely known aircraft engine manufacturer. In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool and formed United Aircraft and Transport Corporation, the predecessor to United Technologies Corporation. His agreement allowed him to carry the name with him to his new corporation. For many years, the companymaintained a plant on New Park Avenue near the Hartford/West Hartford border, where they manufactured machine tools such as their jig-bore machines and other numerically controlled machines. They also manufactured milling machines and twist drills. What remains of the original Pratt & Whitney is now Pratt & Whitney Measurement Systems, located in Bloomfield, Connecticut. 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「Pratt & Whitney Measurement Systems」の詳細全文を読む スポンサード リンク
