John Francis Appleby (1840–1917) was an American inventor who developed a knotting device to bind grain bundles with twine. It became the foundation for all farm grain binding machinery and was used extensively by all the major manufacturers of large grain harvesting machines in the late 19th and early 20th centuries. Appleby's knotting device was a major landmark in the mechanization of agriculture and aided the development of the western wheat fields of the United States. == Background == John Francis Appleby was born in Westmoreland, New York in 1840. In 1844 his extended family of 17 arrived by boat to Milwaukee, Wisconsin. When he was just 18, Appleby invented the basic knotting device that would become the foundation for all farm binding machinery, but no one was interested in the idea at the time. He served with the 23rd Wisconsin Volunteer Infantry Regiment in the American Civil War, from 1862 to 1865. During the war, Appleby invented and patented a manual magazine feed breech loading needle gun. When the US government rejected the idea, Appleby sold the patent for $500.〔Patent No. 45,466, Dec. 20, 1864〕 The weapon was later used extensively by the Prussian Army. 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「John Appleby (inventor)」の詳細全文を読む スポンサード リンク
