Publication number: 20110247190Abstract: Methods of forming a golf club head having improved aerodynamic characteristics are disclosed herein. A preferred method is the largest tangent circle method, which utilizes a Cartesian coordinate system. The method results in identification of the highest point of the crown surface located within a crown apex zone, and this location aids in the design of improved aerodynamic properties of the golf club head.Type: ApplicationFiled: June 22, 2011Publication date: October 13, 2011Applicant: CALLAWAY GOLF COMPANYInventors: D. CLAYTON EVANS, EVAN D. GIBBS, MATTHEW T. CACKETT, STEVEN M. EHLERS

Patent number: 8012041Abstract: A face or face insert (40) for a golf club head (20) is disclosed herein. The face (40) has an interior surface (40b) with a first thickness section (200) and a second thickness region (205). The first thickness section (200) preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (205). In a most preferred embodiment, the first thickness section (200) has an X shape that is rotated around the Y axis (500) by at least 10 degrees. In another preferred embodiment, the face has a first thickness section (200), a second thickness region (205), and a central region (400) having a third thickness. The face or face insert (40) with variable thickness allows for a face or face insert (40) with less mass in a golf club head (20) that conforms to the United States Golf Association regulations.Type: GrantFiled: February 24, 2010Date of Patent: September 6, 2011Assignee: Callaway Golf CompanyInventors: Evan D. Gibbs, Neil Hall, Williams D. Richardson, Larry G. Tang
