Abstract: The present invention provides golf clubs and golf club heads that can be weight adjusted to move the center of gravity of the clubs and heads. The wood-type clubs have heads with crown and soles plates containing weighted and non-weighted sections. The crown and sole plates can be rotated or removed. In this manner, the weighted sections of the crowns and sole plates can be moved to a particular location, and this adjusts the center of gravity of the club head.

Abstract: An improved striking face of a golf club head and a method of manufacturing thereof is disclosed herein. More specifically, the present invention discloses an improved method of stamped forging variable face geometry onto the rear surface of a striking face from a frontal portion of the striking face; wherein the improved process allows for more precise finished parts with less need for complicated machining. The resulting striking face of a golf club head comprises of a substantially planar frontal surface and a substantially non-planar rear surface, wherein the substantially non-planar rear surface is created via a stamped forging process while the substantially planar frontal surface is created via a machining process.

Abstract: A metal wood golf club with a striking face portion made from more than one material is disclosed. More specifically, due to the unique construction of the striking face portion having multiple materials, the present invention utilizes diffusion bonding, liquid interface diffusion, or even super plastic forming techniques to achieve the desirable bond between the more than one material used to form the striking face. The striking face portion is formed by adding a chip insert made from a secondary material that is different from the remainder of the striking face portion substantially near a geometric center of the striking face portion; wherein the secondary material has a higher Young's modulus than the remainder of the striking face portion.

Abstract: A wood-type golf club including a head comprising a body having a face, a sole, a crown, a toe and a heel and a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face. A system is disposed within the body for adjusting club face angle at address comprising an element that is rotatable about a system axis that is substantially parallel to the y-axis to provide at least first and second club face angle positions at address. The element may be any shape which changes club face angle at address. The system axis may alternatively be substantially parallel to the z-axis. Or, the element may even comprise a plurality of interchangeable adjustment portions interchangeably mated with a body portion.

Abstract: A golf club head with a multi-material face is disclosed herein. The layers of the multi-material face are preferably attached to the club head using adhesive and mechanical methods.

Abstract: A golf club head with improved striking face performance is disclosed herein. More specifically, the present invention discloses a golf club head having a thickened central region surrounded by an internal and an external transition region; wherein the thickened central region has an inner perimeter that takes on a shape that substantially resembles the shape of an outer perimeter of the striking face of the golf club head.

Abstract: A set of wood golf clubs have wood club heads with substantially the same external shape. The vertical centers of gravity of the wood club heads are varied by setting the weight within the respective soles and the crowns, while keeping the total weight of the wood club heads substantially constant. The wood club heads have no integral hosel. The wood club shafts are attached to the wood club heads by providing a bore in the wood club head sized to receive the wood club shaft therein, and a threaded fastener that engages the wood club shaft to the wood club head, when the wood club shaft is inserted into the bore. The wood club heads are desirably cast to shape, using casting cores that provide for the shifting of weight between the soles and the crowns within the set.

Abstract: A club head for a golf putter includes a bottom surface, a toe, a heel opposite the toe and a ball striking side on one side of the club head. The ball striking side extends between the toe and the heel and has a center disposed between the heel and the toe. A face insert is carried by a portion of the club head and defines at least part of a ball striking surface on the ball striking side of the club head. The face insert is adapted to absorb energy near the center of the ball striking side so as to produce a coefficient of restitution that is substantially similar and consistent over a majority of the ball striking surface. The face insert deadens the ball striking side at or near the center of the club head so that the distance of putts, whether struck near the center or whether mis-hit and struck closer to the heel or toe, are substantially the same.

Abstract: A golf club iron has a metallic club head including a solid metallic club head body with a bottom surface including a sole that contacts a flat surface when the bottom surface of the club head is placed onto a flat surface, a top surface, a hosel extending from the club head body, and a front face on the club head body. The heel and toe of the club are angled upwardly from a trailing edge central sole region, so that a central sole region has a length of from about 1/4 inch to about 3/4 inch to reduce the potential contact area of the club head with the ground. There is a recess in the rear face of the club head body, with a rim around the recess having a thickness of from about 5/16 inch to about 1 inch measured in the central portion of the rear face of the club head body, to lower the center of gravity of the club head.
