  • Patent number: 6083113
    Abstract: A method of manufacturing a golf putter with a true balance includes the steps of designing or selecting a particular shape and style of putter head and then providing a putter shaft with a longitudinal axis and a neck portion which is integral with the shaft. With the putter head defined, the front-to-rear and toe-to-heel center of gravity cutting planes are accurately deterrnined. The point of attachment for the shaft into the top surface of the putter head via the neck portion is then selected and a plurality of bends in the neck are derived and made so that the longitudinal axis of the shaft passes through the front-to-rear center of gravity cutting plane. The intersection location on the top surface is between the toe of the putter head and the toe-to-heel center of gravity cutting plane. Once the shaft is joined to the head via the neck portion with a slow-setting adhesive, the putter is set on a flat, horizontal surface in order to test to see if there is any turning or rotation.

  • Patent number: 6019686
    Abstract: A golf putter with a face of light weight construction, such as aluminum, and perimeter, heel-toe, weights, such as brass, attached above the striking area of the putter face on stilts that extend upward on the heel and toe of the putter face. The weights constitute the majority of the weight of the putter head. Slots in the stilts through which the weights are attached make the height of the center of gravity of the putter adjustable. When a ball is stroked with the putter with an ascending blow, to diminish the effect of the loft, the friction with the ball and the putter face allows the vertically high moment of inertia to impart overspin to the ball because the putter head rotates as such slightly at the moment of impact. When a ball is stroked with the putter with a descending blow, the putter head rotates slightly causing the friction of impact to break which allows the balls contact and friction with the putting green to have a greater effect on how the ball starts rolling.

  • Patent number: 5820481
    Abstract: The present invention defines an improved golf putter employing an elastomeric material between the putter face and body to dampen vibrations caused by impact of the moving putter face on a golf ball, the vibrations being directed by the putter body configuration in such a way as to maximize the dampening function. With a double bend in the putter shaft to located the line of impact with the center of rotation of the head, the design further improves feel and stroke through face bottom weighting. Angular design of the face, bottom and heel acts to decrease potential blade turf drag, enhancing the smooth feel of the club system.

  • Patent number: 5803824
    Abstract: A golf putter having a lie and offset adapter for selectively setting and/or adjusting the lie and offset of the putter. The adapter may comprise a spacer having a lower socket extending from a first end along a first longitudinal axis and a second socket extending from a second end along a second longitudinal axis. The length of the spacer and the orientation of the sockets are set to provide the desired lie and offset of the putter. The golf putter has a head with a face for striking a golf ball, a lower shaft segment and an upper shaft segment. The head is connected to a lower shaft segment which, in turn, is attached to the lower socket of the adapter. A lower end portion of the upper shaft segment connects to the upper socket of the adapter. Alternatively, the open end of a hosel, which extends from the putter head, may take the place of the lower shaft segment. The lie and offset of the putter are selectively set during assembly by installing an adapter configured for the desired lie and offset.

  • Patent number: 5800283
    Abstract: In a kneeling putter, a shaft is secured to and obliquely risen on a top of a head at its central portion toward a player. The shaft has grips at upper and lower ends thereof and has a length of 65 cm which is shorter than that of the conventional putter. Thus, it is possible to eliminate, to the utmost, a deviation and a gap existing with the use of the conventional golf putter between a ball putting direction and a sight line when the player sights the ball putting direction, thereby providing a great improvement in accuracy of putting by a simple putting motion.

  • Patent number: 5785602
    Abstract: The Cue Putter is unique golf club, far superior in design to existing putters. It is designed to maximize a golfer's putting accuracy and consistency. The Cue Putter consists of a wooden club shaft, a guide block, rubber "O"-rings, and a transparent Plexiglas clubhead. The Cue Putter is designed to be used while kneeling on the green, with the putter's shaft aligned and used parallel to the putting surface. The Cue-Putter is gripped with one hand, and the stroke is executed primarily with the fingers and wrist instead of the arms and shoulders used with traditional putters. This improves the golfer's putting "touch" tremendously, because the innate precision of the hand and fingers cannot be matched by the larger muscle groups of the arms and shoulders. The Cue Putter also provides an ideal, "real time" view of the slope and undulation of the green, instead of a vague, "mental snapshot" taken while the golfer crouches down yards behind the ball prior to assuming his stance.
