Patent number: 10406407Abstract: A golf club head having elevated internal weighting that improves ball speed, reduces backspin, and increases launch angle is disclosed herein. In particular, the golf club head comprises a hollow body with a face, sole, and elevated weight bar, which is disposed inside the body and is fixed to heel and toe sides of the body, preferably with mechanical fasteners such as screws or bolts. The weight bar bridges a central portion of the sole, and a central section of the weight bar, which preferably comprises at least 50% of the overall mass of the weight bar, extends towards the face without actually making contact with the face. The sole also includes at least one slot extending perpendicular to the face and underneath the central section of the weight bar, the slot having a front-to-back length that is greater than a maximum front-to-back length of the weight bar.Type: GrantFiled: April 1, 2019Date of Patent: September 10, 2019Assignee: Callaway Golf CompanyInventors: Brandon D.

Patent number: 9855476Abstract: A golf club head having multiple structural columns is disclosed herein. A body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior. Each of the structural columns extends from the crown or return section to the sole section within the hollow interior to reduce stresses placed on the face section during impact with a golf ball. The structural columns are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.Type: GrantFiled: June 20, 2017Date of Patent: January 2, 2018Assignee: Callaway Golf CompanyInventors: James A.
