  • Patent number: 5884409
    Abstract: A device for clamping a golf club to a base including a clamping mechanism adapted to clamp the face of the golf club at a predetermined angle with respect to the base, and a measuring mechanism including at least a loft scale operational in combination with the clamping mechanism wherein the loft scale is pivotable about an axis parallel to the club face, further including measuring scales for reading loft angles of the club and optionally including scales for measuring the lie angle of the club.

  • Patent number: 5421098
    Abstract: An apparatus for adjusting the loft and lie of a golf club head. The invention includes three components. The first is a fitting gauge removably attachable to the shaft for identifying the ideal angles of the loft and lie of the club. The fitting gauge includes a first indicator for measuring the loft angle and a second indicator for measuring the lie angle. The second component of the invention is a bench to which the golf club head is attached. The bench includes a lie reading gauge and a loft reading gauge. The bench may be used for either left-handed golf clubs or for right-handed golf clubs. The third component is an adjusting tool that may be removably attached to the hosel of the club fixed to the bench. The shaft of the club is manipulated relative to the golf club head to adjust the actual lie and loft angles to match the ideal angles of loft and lie by movement of the adjusting tool.
