William Dana Ewart
William Dana Ewart (1851 - 1908) invented and patented the linked belt, a square detachable link for chain belts, on September 1, 1874. The metal chain "linked belt" replaced the leather and strap belts used on agricultural equipment at the time.
A resident of Belle Plaine, Iowa, Ewart was a farm-implement dealer when he conceived of the idea.〔Wilson, Bill. (June 2001) "Crane producer continues to strengthen customer base worldwide " ''Roads & Bridges'' June 2001 Volume: 39 Number: 6.〕 In 1875 Ewart established the Ewart Manufacturing Co. in Belle Plaine, Iowa. In 1880 he founded the Link-Belt Machinery Company and in 1888 the Link-Belt Engineering Company.〔(LBX Company History )〕 In the early 1890s, Ewart's companies produced the first wide-gauge, steam-powered, coal-handling clamshell crane, the further development of which would eventually lead to the modern Link-Belt construction equipment.〔(History of Link-belt Construction Equipment Company )〕〔(ConstructMyFuture Hall of Fame )〕 Link-Belt chain drives were used in a variety of applications, including auto assembly lines, coal mining, concrete mixers, and agricultural machinery.〔(Pennsylvania Historical Society, Papers of Frederic V. Hetzel )〕
Ewart was inducted into the Association of Equipment Manufacturers Hall of Fame:〔(【引用サイトリンク】work= Association of Equipment Manufacturers Hall of fame web site )〕
in 1996 at CONEXPO-CONAGG.
