  • Iron-type golf club head
    Publication number: 20070026967
    Abstract: The present invention provides an iron-type golf club head comprising a primary cavity that is approximately parallel to the ground when the club head is resting at normal address. A secondary cavity, positioned within the primary cavity, has a bottom wall that is approximately parallel to the club face and is positioned above the club head sole. An interior wall that forms the secondary cavity is uniform in height while increasing in width in a bottom segment thereof.

  • Golf club head having an insert cavity rear aperture
    Patent number: 7112147
    Abstract: A golf club head includes a body having a front face with a cavity formed therein. The cavity has at least one aperture passing through the cavity bottom wall to the rear surface of the club head body. A face insert is installed in the cavity by applying an adhesive layer between the face insert and the bottom of the cavity. As the face insert is pressed into the cavity, air and any excess adhesive escapes through the aperture to the rear surface of the club where it can easily be removed by wiping with solvent.

  • Golf putter head with a visual alignment aid and an increased moment of inertia
    Patent number: 7086957
    Abstract: A golf putter head includes a face member with a front surface arranged for impacting a golf ball. A first arm extends substantially rearwardly from a heel end of the face member, a second arm extends substantially rearwardly from a toe end of the face member, and a central member extends rearwardly from the face member intermediate the heel and toe ends thereof. The central member is connected to and extends rearwardly from a back surface of the face member. The central member is connected to the first and second arms rearwardly of the face member. The first and second arms have top surfaces that slope downwardly as the first and second arms extend away from the face member.

A first arm extends substantially rearwardly from a heel end of the face member, a second arm extends substantially rearwardly from a toe end of the face member, and a central member extends rearwardly from the face member intermediate the heel and toe ends thereof. The central member is connected to and extends rearwardly from a back surface of the face member. The central member includes a pair of wing portions connecting the central member to the first and second arms rearwardly of the face member. An end portion of the central member extends rearwardly of the wing portions.

  • Method of manufacturing a golf club head with a variable thickness face
    Publication number: 20060063606
    Abstract: A method of manufacturing a golf club head with a variable thickness face having a central thickened region surrounded by a transition region tapering from the central thickened region to a thinner peripheral region. The method includes locating a ball end mill revolving about an axis generally normal to the inner surface of the face plate at an initial location on a circumferential intersection between the outer edge of the central thickened region and a transition region. The inner surface of the face plate is machined by moving the revolving ball end mill in a radial direction outwardly toward and through the transition region and the peripheral region to machine the inner surface of the face plate creating a tool channel having a width as the ball end mill traverses the transition region and thereby vary the thickness of the face plate in the tool path.

  • Golf club head weight adjustment member
    Publication number: 20060025234
    Abstract: The present invention relates to certain weight adjustment members that can be used in connection with iron-type golf clubs. The weight adjustment members of the present invention comprise a relatively uniform and/or symmetrically configured width. In addition, the members comprise a substantially linear back-side. The weight adjustment members of the present invention, therefore, provide a consistent level of performance across the members and, moreover, can be mass produced using more simplified molds when compared to other members known in the art. Still further, the present invention provides iron-type golf heads and golf clubs that comprise the weight adjustment members of the present invention.
