Publication number: 20210077869Abstract: A golf club head includes a club body including a crown, a sole, a skirt disposed between and connecting the crown and the sole and a face portion connected to a front end of the club body. The face portion includes a geometric center defining the origin of a coordinate system when the golf club head is ideally positioned, the coordinate system including an x-axis being tangent to the face portion at the origin and parallel to a ground plane, a y-axis intersecting the origin being parallel to the ground plane and orthogonal to the x-axis, and a z-axis intersecting the origin being orthogonal to both the x-axis and the y-axis. The golf club head defines a center of gravity CG, the CG being a distance CGY from the origin as measured along the y-axis and a distance CGZ from the origin as measured along the z-axis.Type: ApplicationFiled: October 6, 2020Publication date: March 18, 2021Applicant: Taylor Made Golf Company, Inc.Inventors: Todd P.

Patent number: 10780327Abstract: Disclosed golf club head bodies are cast of 9-1-1 titanium with the face plate being cast as a unitary part of the body along the with crown, sole, skirt and hosel. Due to the 9-1-1 titanium material, the face plate and other portions of the body can have a reduced alpha case thickness and resulting greater durability. This can eliminate the need to reduce the alpha case thickness using hydrofluoric acid or other dangerous chemical etchants. Casting methods can include preheating the casting mold to a lower than normal temperature, to further reduce the amount of oxygen transferred from the mold to the 9-1-1 titanium during casting.Type: GrantFiled: August 9, 2018Date of Patent: September 22, 2020Assignee: TAYLOR MADE GOLF COMPANY, INC.Inventors: Bing-Ling Chao, Matthew David Johnson, Matthew Greensmith
