Abstract
Abstract An improved wood-type golf club having a club head in which a recess is formed, the recess being filled with an insert, a dense weighting means within the insert, and a layer of an impact resistant resin within the insert holding the weighting means therein, the weighting means being positioned to provide a center of gravity for the club head which is closer to the leading edge of the club face than in the absence of the weighting means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A wood-type golf club comprising a club head having a recess in the striking area, an insert filling said recess, a dense disk weighting means within said insert, a layer of an impact resistant resin within said insert covering one face and at least a portion of the periphery of said disk, the layer of resin having a smoothly contoured, uninterrupted surface forming part of the striking face of said club, the disk weighting means being positioned to provide a center of gravity for said club head which is closer to the leading edge of the club face than in the absence of said weighting means.
Claim 2
Dependent Claim
106 words
A wood-type golf club comprising a club head having a recess in the striking area, an insert filling said recess, a dense disk weighting means within said insert, a layer of an impact resistant resin within said insert covering one face and at least a portion of the periphery of said disk, the layer of resin having a smoothly contoured, uninterrupted surface forming part of the striking face of said club, the disk weighting means being positioned to provide a center of gravity for said club head which is closer to the leading edge of the club face than in the absence of said weighting means.
Claim 3
Dependent Claim
30 words
The golf club of claim 1 in which said weighting means is positioned so that center of gravity is substantially in the plane which bisects the shaft of the club.
