  • Golf club head with structural tension cable
    Patent number: 10512826
    Abstract: The disclosure is directed to a golf club head having an adjustable tension cable disposed proximate the face. The body has a face, a sole, and a return section, and defines a hollow interior. The cable extends between the return section and the sole within the hollow interior near the face to reduce stresses placed on the face during impact with a golf ball. The cable preferably forms a woven structure, with multiple connections between the return section and sole, and the tension in the cable is adjustable via a screw connected to one end of the cable that engages a threaded bore disposed near the hosel.

  • Golf club head with adjustable weighting
    Patent number: 10486039
    Abstract: A golf club head comprising a means for adjusting the location of the center of gravity and a slidable weight assembly are disclosed herein. The club head comprises two channels, each having at least one shoulder portion, a floor, and a rail extending upwards from the floor. The channels intersect at a junction, and a slidable weight comprising a top portion, a mechanical fastener, a clamping structure, and a keyed, anti-rotation structure is disposed within at least one of the channels. When the mechanical fastener is tightened, the top portion presses against the at least one shoulder portion and pulls the clamping structure upward so that the clamping structure grips the rail. The rails are spaced from one another at the junction, and the clamping structure allows the slidable weight to be moved into either of the channels without being indexed.
