Abstract
A body member has a first passageway extending transversely thereof adjacent the forward end and opening through the side surfaces of the body member. A second passageway opens in from the front and communicates with the first passageway at a point intermediate the sides of the body member. A flap valve is provided on each side surface and is hinged at its forward end relative to the side openings to allow only outward flow of water from the transverse passageway through the sides. A ball is freely movable in the transverse passageway and is associated with its flap valves for controlling outward flow of water through one or the other of the flap valves depending upon the position of the ball resulting from gravitational or side thrust forces acting on the body member. The movement of the ball relative to the valves causes unbalanced water pressure discharging through one or the other of the side openings to cause the body member to change directions and swim in a darting pattern similar to a minnow. In a second embodiment a shiftable weight is provided as well, to control diving forces of the body member.
