<p>APPLICANT: LARS G.G. NORLIN TITLE: WOBBLER In a wobbler, an elongate cavity has an end portion divided in two side chambers by a longitudinal partition wall in a plane at right angles to the spoon of the wobbler. At the end of the partition wall a weight-loaded flap slopes in one direction or the other depending on the twist position of the wobbler. One or more balls roll back and forth in the cavity and side chambers. When in one side chamber the balls twist the wobbler to steer out to one side and with the balls in the other side chamber the wobbler is twisted to steer out to the other side. By releasing the line the wobbler rises and the balls roll backwards, and forwards again when the line is tensed anew. During this back and forth rolling movement the flap steers the balls over from one side chamber to the other.</p> |
