  • Golf club head with high toe and low heel weighting
    Patent number: 5224705
    Abstract: A golf club head is provided with a cavity which has a pair of side walls which extend at an angle of about 0.degree. to about 50.degree. to the hosel of the club head. The shape of the cavity positions a substantial portion of the weight of the club head in the upper portion of the toe of the club head and in the lower portion of the heel of the club head. The orientation of the weight of the club head provides a substantial moment of inertia about an axis which extends through the center of gravity at an angle of about 45.degree..

  • Golf club with bulge radius and increased moment of inertia about an inclined axis
    Patent number: 4471961
    Abstract: A golf clubhead has weight distributed on opposite sides of a non-vertical axis which extends through the center of gravity of the clubhead in a plane which intersects the axis of the shaft above the clubhead to provide more accurate off-center hits. Wooden clubs are provided with bulge and roll which curve, respectively, about said axis and an axis perpendicular thereto. The radius of the roll is increased to make the loft of the club substantially uniform from top to bottom.
