Abstract: Disclosed herein is a head fixture for adhesively bonding a part of a golf club head to a body of the golf club head. The head fixture includes a bottom portion, including a body retainer, and a top portion, selectively attachable to the bottom portion and including pressure applicators spaced apart about the top portion. Each one of the pressure applicators comprises a ratcheting mechanism and a ribbed shaft engaged with the ratcheting mechanism such that, when the top portion is selectively attached to the bottom portion, the ribbed shaft is movable away from the body retainer into a position, associated with a pressure applied to the part of the golf club head by the ribbed shaft, and the ribbed shaft is non-movably fixable, relative to the body retainer, in the position.

Abstract: A golf club head in accordance with the invention includes a front wall defining a forward striking face having an engineered texture thereon. The engineered texture includes a prescribed, regular pattern of discrete, geometric shapes spaced at least 0.1 mm apart from each other, each shape having a volume that is less than 0.0007 mm3. Preferred methods of manufacturing the engineered texture of the forward striking face include treating the face by chemical etching, precision micro-saw-cutting, and laser cutting. The engineered texture enhances the performance of the golf club head upon striking a golf ball, providing one or more of an increased high backspin, a lower launch angle, and a higher balls speed, as compared to a golf club head not incorporating such an engineered texture.

Abstract: A golf club head in accordance with the invention includes a forward striking face that comprises a substantially planar recessed surface and a plurality of discrete, solid geometric shapes projecting forward from the recessed surface. Each of the geometric shapes has a volume of less than 0.0007 mm3. The distance along the recessed surface between adjacent shapes is at least 0.1 mm. The total volume of the geometric shapes contained with a square reference region measuring 2.5 mm by 2.5 mm is less than 0.05 mm3.

Abstract: An iron-type golf club head is disclosed that comprises a striking face, a heel, a toe and a sole bar, wherein a recess is formed in the sole bar. A cartridge comprised of a first material at least partially disposed the sole recess, and at least one pin, comprised of a second material coupled to the cartridge. The first material has a modulus of elasticity that are less than that of the second material.

Abstract: The present invention resides in a perimeter-weighted, iron-type golf club head incorporating one or more internal chambers. The golf club head has a face plate defining a striking face of the club head and a body having an annular mass disposed behind the striking face. The annular mass extends about a periphery of the face plate defining an external cavity on a rear side of the face plate. The annular mass includes a top portion extending along a top edge of the face plate, a toe portion extending along a toe edge of the face plate, a heel portion, and a bottom portion. At least one internal chamber is located adjacent to the top edge, as defined by the top portion of annular mass. The club head also includes a weight member disposed in a recess defined by the bottom portion of the annular mass. The internal chamber, or a selected number of a plurality of internal chambers defined by the annular mass, can be filled to further manage the weight distribution of the club head.

Abstract: A golf club head is provided, including a planar face with a pattern of horizontal grooves therein each having a cross section with an opening in the planar face. The grooves each include a first side, a second side, a pair of top junctures where the first and second sides join the planar face, a bottom and a pair of bottom junctures where the first and second sides join the bottom. The spacing between the first and second sides continually increases from the bottom to the top junctures. Each of the sides includes a lower section positioned nearer the bottom and an upper section positioned nearer the face. Each of the lower and upper sections is substantially planar. The top junctures are convexly rounded and the bottom junctures are concavely rounded.

Abstract: A golf club head is disclosed that comprises a body having a striking face, a rear cavity and a sole bar, wherein a recess is formed in the sole bar that extends generally from the rear cavity. An insert is located within the sole recess, the insert including a core and an intermediate layer that separates the core from the recess wall. The intermediate layer has a hardness and a modulus of elasticity that are less than that of the core, such that when the golf club head is used to strike a golf ball, the resulting vibrations are dissipated by compression of the intermediate layer and movement of the core with respect to the intermediate layer.

Abstract: An iron-type golf club head incorporating one or more internal chambers provided in the top portion of a perimeter weighted iron club head is provided. The golf club head has a face plate defining a striking face of the club head and a body having an annular mass disposed behind the striking face. The annular mass extends about a periphery of the face plate defining an external cavity centrally located on a rear side of the face plate. The annular mass includes a top portion extending along a top edge of the face plate, a toe portion extending along a toe edge of the face plate, a heel portion, and a bottom portion. At least one internal chamber is located adjacent to the top edge, as defined by the top portion of annular mass. The internal chamber, or a selected number of a plurality of internal chambers defined by the annular mass, can be filled to further manage the weight distribution of the club head. Thus, the club head can be tuned to accommodate requirements of an individual golfer.

Abstract: A set of iron golf clubs is disclosed, each golf club having a head configured to provide enhanced flexibility for launching a golf ball. An upper portion of the body of each head has a reduced stiffness, while a lower portion of the body is configured with recesses that provide reduced stiffness toward the heel and the toe. A low central region supports the head at impact with the golf ball. The relative stiffness in the lower portion of the club head, varying from heel to toe, is designed in conjunction with a top to bottom difference in stiffness. Thus, the golf club head has enhanced flexibility and selectively increased stiffness, for improved performance and feel.

Abstract: A golf club putter head having putter body with a toe region, a central region, and a heel region, the central region having a front recess and a rear recess separated by a central wall joining the heel and toe regions. Front and rear inserts are disposed within the respective front and rear recesses. This construction affords structural integrity and greater manufacturing ease over the construction of putters having toe and heel regions that are entirely separated from each other. The inserts preferably are formed of materials having a lower density than that of the putter body, with the particular material being selected according to a golfer's preference in feel. A decorative element can be included with the rear insert, to achieve final head weighting and cosmetic appeal. The thickness of the central wall, and the density and thickness of the inserts, are selected to provide the putter head with a desired moment of inertia.
