  • Publication number: 20120077615
    Abstract: A golf putter providing a mount of the hosel to the club head and a shaft engagement to the hosel adjacent to the heel end of the club head. The mount provides the sole engagement of the hosel to the head as a gap is formed by a pathway formed through the body of the head which is larger than the circumference of the hosel in its communication therethrough. The engagement provides better touch to the user and feedback on striking a ball while concurrently removing the shaft from the user's line of sight to the ball and club face and reduces the twist or torque at impact with a golf ball, thereby increasing the moment of inertia. An arc-shaped section of said hosel is employable to further balance the club on the hosel and with the shaft.

  • Patent number: 8070622
    Abstract: A golf putter providing a center mount of the hosel to the club head and a shaft engagement to the hosel at the heel end of the club head. The center mount provides the sole engagement of the hosel to the head as a gap is formed by a pathway formed through the body of the head which is larger than the circumference of the hosel in its communication therethrough. The centered engagement provides better touch to the user and feedback on striking a ball while concurrently removing the shaft from the user's line of sight to the ball and club face and reduces the twist or torque at impact with a golf ball, thereby increasing the moment of inertia.

  • Patent number: 5377980
    Abstract: A golf club having a mechanism permitting adjustment of the shaft angle relative to the club head. Fixed stops limit the range of angular adjustment. The body of the club head has a central opening extending to the sole of the club. The opening is closed by a sole plate that requires a special tool for removal and reinstallation. A serrated surface secured to an extension of the club shaft within the opening mates with a corresponding serrated surface secured to the club head. The angle of the shaft relative to the head is locked by installing the sole plate which forces the two serrated surfaces together. In order to change the shaft-to-head angle, the sole plate must be loosened sufficiently to permit the cooperating serrations to disengage and be moved relative to each other.

  • Patent number: 5292123
    Abstract: A golf club with a shaft angularly adjustable relative to the head through selected angles. A special tool must be used to allow any angular adjustments between shaft and head. A structural stop limits the maximum and minimum angles of adjustment between the head and shaft.

  • Patent number: 5290035
    Abstract: A golf club that produces a smoother stroke, does not attempt to turn in the golfer's hands, and provides superior feedback to the golfer comprises a putter head, a shaft, and a grip. The putter head comprises an elongated body having a toe end, a heel end, a fore side including a ball striking face, an aft side opposite said fore side, a sole, and a top side. A longitudinal axis runs heel to toe parallel with the ball striking face. The head includes two chambers that increase the proportion of heel and toe mass relative to the center mass and decrease the transverse cross sectional area of head material and thereby increase vibration up an attached shaft upon ball impact. The chambers each exit the top side in a transverse slot. The transverse slots are approximately a ball width apart and equal distance on each side of the center of mass of said head. The entire putter is balanced so as to be more stable in a golfer's hands. A neutrally balanced putter has no moment about the shaft axis.
