US Patent No. 1,718,198, granted June 18, 1929 to John Almond of Methuen, Massachusetts, assignor to the Draper Corporation, for a harness motion (shed-forming mechanism) for looms. The mechanism is a compact set of bell-crank levers and cams placed beneath the harness frames and inside the loom frame. The levers connect to the frames by flexible straps running around idler pulleys, so the frames always move vertically. The document includes two sheets of drawings (side and plan views), the description, and eight claims.
