  • Golf club driver with center of gravity movable during swing
    Patent number: 3951413
    Abstract: A golf club head has a hollow passageway partly filled with mercury oriented so that it will shift position and therefore change the balance and center of gravity of the club during a golfer's swing. The passageway provides for a shift of weight toward the toe of the head as the torque of a golfer's swing increases.
