Abstract: A drive system for animating a hunting decoy is designed to fit within the decoy's hollow body and provide movement to appendages, such as wings, on the decoy. The drive system comprises a battery-operated DC motor for imparting reciprocal movement of mounting pegs on which the appendages are affixed. The oscillating, reciprocating motion is provided by an eccentric that is coupled through flexible leaf spring links to the periphery of first and second wheels that are journaled for rotation on parallel axes. The leaf spring linkages function to counter-balance the weight of the appendages, reducing current drain on the motor.
