US Patent 4,566,499 (granted January 28, 1986) describes an electronic jacquard mechanism for controlling warp shedding on a loom. Solenoids are mounted directly on a printed circuit board, and their movable cores are fixed to the dropper needles, so the needles are selected by computer command rather than by punched pattern cards. The document includes the abstract, claims, description of the embodiments, and four sheets of patent drawings. It also includes a USPTO database printout of the text and a copy of the printed patent.
