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.
Claims5
An apparatus for creating life-like movements in floating decoys comprising:
- (a) a submersible frame comprising two arcuately-shaped tubular members hingedly connected to one another at their ends to which said decoys are attached by flexible lines,
- (b) an elastic band anchored at one end away from said frame, said band being attached at its opposite end to said frame, and
- a motor having a reel attached to a shaft of said motor for reeling in and out a reel line attached at one end to said frame and attached at is opposite end to said reel, wherein said motor is provided which turn said motor on and off at time intervals which are vareid by voltage to said timers, said voltage being generated by the backspin on said motor shaft caused by the contraction of said elastic band.
An apparatus for creating life-like movement in floating decoys comprising:
- (a) a submersible frame to which said decoys are attached by flexible lines,
- (b) an elastic band having a pre-determined elasticity anchored at one end away from said frame, said band being attached at its opposite end to said frame, and;
- (c) an electric motor having a rotatable shaft to which is attached one end of a reel line, said reel line being attached at its opposite end to said frame, and
- (d) means for turning on and off said motor at time intervals which are varied by voltage to said timers, said voltage being generated by the backspin on said motor shaft caused by the contraction of said elastic band.
