William Dana Ewart
(deceased)

Ewart invented the linked belt in 1874, a square detachable link for chain belts that became the standard for modern mechanical power transmission still in use today. In 1880, he founded the Link-Belt Machinery and Link-Belt Engineering Companies. Ten years later, his companies developed the first wide-gauge, steam-powered, coal-handling clamshell crane, the ancestor of today's Link-Belt construction equipment.
