US Patent No. 3,289,707 granted to Victor Wittendal of Croix, France, for an open-shed Jacquard machine whose hook needles are moved by a double positive action. The patent describes flexible main needles with right-angle bends that are pushed by one series of bars and pulled by another, replacing springs and pulley-block arrangements. It also describes double-armed hooks with inward-facing upper noses, arresting bars, and deflecting members, and it gives three claims. Three sheets of drawings (Figs. 1-3) show the machine at successive stages of its cycle.
