US Patent 3,103,953 by William Lauritsen of Sweden describes a shedding mechanism for looms in which each heald has an armature at both ends and a small number of permanent or electromagnets operate all the healds. Selectors (pins or needles), driven by compressed air or vacuum under control of Jacquard-type perforated pattern cards or bands, choose which healds follow which magnet. The patent has four sheets of drawings (Figs. 1-7), a description of the comber boards and eccentric-rod drive, and 15 claims.
