George received his first patent for an electrical service entrance safety switch in 1907. This device reduced the likelihood of accident or fire and enabled homeowners to replace their own fuses. He received an additional 15 patents in the field between 1907 and 1925. Harry Wadsworth left the business in 1910.〔 ==Expansion== The company incorporated in 1918 and moved from an address on Madison Avenue to a Pike Street address. By 1922, the company had grown to 100 employees and $1.5 million in sales. That year, the company announced the construction of a new building on 11th Street, Covington, Kentucky. The building was completed in March 1923. In 1925, George Wadsworth sold his rights to 16 patents to a Cincinnati company and resigned from Wadsworth Electrical Manufacturing. David Wadsworth, George's brother, was appointed vice president and chief engineer in 1927 and continued George's record of innovation until his death in 1937.〔 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「Wadsworth Electric Manufacturing Company」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
