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

1. 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.

2. 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.

3. The golf club of claim 1 which includes an annular recess in said insert forwardly of said weighting means for anchoring said layer of resin within said annular recess.

4. The golf club of claim 1 in which said insert includes an angular taper in said recess for locking said layer of resin therein, said recess having a larger diameter at its base than at its striking face.

5. The golf club of claim 1 in which said resin is an epoxy resin.

6. A wood-type golf club comprising a club head having a wedge-shaped recess therein in the striking area, a wedge-shaed insert received within said recess, said insert having a bore with a relatively shallow recess at its innermost extremity, a weighting disc overlying and closing off said shallow recess, a layer of adhesive in said shallow recess securing said disc thereagainst, said bore in said insert having a flared portion of increased diameter spaced from said striking face, and a layer of impact resistant resin filling said bore about said disc and having a large diameter radius surface forming the striking area of said club.

7. The golf club of claim 6 which includes an annular groove in said insert between said shallow recess and said striking face for receiving said resin in locking engagement.
