Patent number: 9597561Abstract: A golf club head comprising a body, at least one weight cartridge, and a plurality of hollow tubes is disclosed herein. The body comprises a face section, a sole section, and a return section, and also defines a hollow interior. Each of the plurality of hollow tubes extends from the return section to the sole section to reduce stresses placed on the face during impact with a golf ball, and the at least one weight cartridge is sized to fit within at least one of the plurality of hollow tubes. The sole section and return section each comprise keyed apertures providing access to the hollow tubes with which they communicate, and the at least one weight cartridge comprises a keyed structure sized to fit through the keyed apertures.Type: GrantFiled: January 25, 2016Date of Patent: March 21, 2017Assignee: Callaway Golf CompanyInventors: James A.

Patent number: 8715106Abstract: The present invention discloses an iron-type golf club head having features that permit adjustment to the principal moment of inertia angle, the center of gravity location, and overall club forgiveness. In particular, the golf club head includes a rear cavity sized to receive a weight cartridge composed of one or more materials, the adjustment of which changes one or more of the mass properties of the golf club head and may change the interaction of the golf club head with turf during play, and a composite face plate. The weight cartridge may comprise one or more high density materials, and may be located in or proximate the sole.Type: GrantFiled: January 9, 2013Date of Patent: May 6, 2014Assignee: Callaway Golf CompanyInventors: James A. Seluga, Sean Griffin, Evan D. Gibbs

Patent number: 8376876Abstract: 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: August 29, 2011Date of Patent: February 19, 2013Assignee: Callaway Golf CompanyInventors: Evan D.

Patent number: 8317636Abstract: 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 and measurement of certain club head features, which can be adjusted to improve aerodynamic properties of the golf club head. One method of the present invention lowers the drag of the club head by specifying dimensional relationships of the driver head based on location of apex and nadir points, while another method lowers the drag of the club head by improving overall face design.Type: GrantFiled: January 24, 2012Date of Patent: November 27, 2012Assignee: Callaway Golf CompanyInventors: D.
