Abstract: A golf putter head has a generally triangular shape where a ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading wall and trailing wall are interconnected at their respective opposite ends by sidewalls that converge toward one another and define a cavity having a trapezoidal shape. The center of gravity of the golf putter head is closer to the trailing wall than the leading wall so that a moment of inertia is generated that reduces the effects of missing a sweet spot on the leading wall during a putt. In a second embodiment, the trailing wall is weighted to move the center of gravity still closer to the trailing wall. In a third embodiment, a web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head, dividing the cavity into two equal-sized cavities.

Abstract: A golf putter head of triangular shape. A ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading and trailing walls are interconnected at their respective opposite ends by sidewalls that converge toward one another. A web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head. A first embodiment may include a trailing copper weight and side wall aluminum weights. A second embodiment may include three copper weights, a third embodiment may include three copper-tungsten weights, and a fourth embodiment may include three tungsten weights. The weights are removable so that a putter having a low swingweight or a high swingweight can be brought up to or down to a standard swingweight. The weights may also be mixed in the second, third, and fourth embodiments.

Abstract: A chest putter or a belly putter construction includes a putter shaft having a bore formed in its proximal end that is adapted to slidingly receive a shaft extension. A friction fitting between the putter shaft and the shaft extension provides a temporary connection so that a prospective purchaser may try a plurality of shaft extensions of varying lengths in an effort to find a particular shaft extension which when combined with a putter shaft provides a proper length. When a desired length is found, an adhesive is employed to permanently bond the particular shaft extension to the putter shaft. The resulting chest or belly putter has a fixed length that complies with the rules of professional and amateur golf.

Abstract: 10A golf putter having a moment of inertia in the 12,000-28,000 gm/cm2 range. The main body of a putter blade is disposed in trailing relation to a ball-striking surface and includes a frame part formed of a preselected light-in-weight material. The frame part has enlarged openings at its toe and heel ends for receiving toe and heel weight members. The toe and heel weight members are formed of a preselected material heavier than the material that forms the frame part. One embodiment has a length of about seven and one-half inches, a weight of about five hundred fifty grams, and a moment of inertia of about 28,000 gm/cm2.

Abstract: A method for making a blade putter having a high inertia of rotation. The product of the method has a base, a ball-striking part, a toe weight and a heel weight. The base is made of a first material of relatively low mass, such as aluminum, and the other parts are made of a second material having a relatively high mass, such as copper or brass. A dovetailed groove is formed in the toe end of the base to slidingly receive a dovetailed protuberance formed in the toe weight and a dovetailed groove is formed in the heel end of the base to slidingly receive a dovetailed protuberance formed in the heel weight. A recess formed in a leading wall of the base receives the ball-striking part. Fasteners hold the parts together as they are machined so that respective perimeters of the weights are flush with the base. The fasteners are then removed and the base is anodized separately from the other parts.

Abstract: A golf club head having two layers of differently colored, material. One layer is molded with projections, and the other with corresponding recesses, into which the projections fit and are visible from the front strike face of the insert. In a preferred embodiment the projections include a border surrounding the strike face insert having a color selected in combination with an adhesive to mask the appearance of the adhesive at the strike face.

Abstract: A putter head having a back face undercut is disclosed. The undercut is a section cut into the sole, thereby forming an undercut back face perpendicular to the sole and substantially parallel to the strike face. The undercut results in enhanced heel/toe weighting and an elevation of the center of gravity of the putter head. The undercut back face preferably includes a logo or other indicia that is visible when viewing the back face of the putter, but that is not visible when viewing the putter from above.
