  • Duck decoy movement apparatus
    Patent number: 4535560
    Abstract: An apparatus for controlling the movement of a group of duck decoys having a decoy support frame attached at one end to an anchored elastic band and at its other end to a line which is attached to a reel and motor. Movement of the decoys is controlled by a voltage controlled timer which turns on and off at variable time intervals. The voltage is generated by the backspin on the motor shaft caused by contraction of the elastic band which has been stretched while the motor is turned on.
