Abstract

A golf club having provision for adjusting the swing weight and balance of the club. The club head includes a plurality of elongated cavities, each of which mounts an internally threaded sleeve. One or more externally threaded plugs are threadedly retained in each sleeve, the plugs being adapted to be rotatably translated along the length of the sleeve, or entirely removed therefrom, to change the balance and/or swing weight of the club.

Claims

1. A golf club comprising, an enlarged substantially solid head including a plurality of cavities communicating with one surface of said head, means for adjusting the distribution of weight in said head, said means including an internally threaded sleeve mounted within each cavity and a plurality of externally threaded plugs each having at least one rounded end adapted to be threadedly mounted in each sleeve and adapted to be selectively located in any portion thereof, the rounded end of the respective plugs serving to limit the area of contact with each other to preclude transmission of a driving torque therebetween whereby an inner plug will not be rotated in the event the second plug is advanced into engagement therewith, a resilient thread locking means mounted on each of the plugs and carried by a portioN of the external surface of the plugs for frictionally engaging the internal threads of said sleeve for holding the plugs in the desired adjusted position, said resilient thread locking means and the threads of the plug collectively serving as the sole means for maintaining the plug in the desired adjusted position, said one surface of the club head having plate means, and headed screws penetrating said plate means and threadably received in each of said sleeves for securing said plate means to the club head.

2. The golf club as defined in claim 1 wherein said head includes a relatively flat base surface, and a generally vertically extending striking face, and said cavities communicate with said base surface and extend along axes substantially perpendicular to said base surface.

3. The golf club as defined in claim 1 wherein said head includes a relatively flat base surface, and a generally vertically extending striking face, and said cavities communicate with said striking face and extend along axes substantially perpendicular to said striking face.

4. The golf club as defined in claim 1 wherein the external surface of each sleeve is threaded to retain said sleeve in said cavity.

5. The golf club as defined in claim 1 wherein the external surface of said sleeve includes a highly pitched thread to retain the sleeve in said cavity, and the outer end of said sleeve includes engagement means for facilitating rotational advancement of the sleeve into the cavity.

6. The golf club as defined in claim 1 wherein said plate means is a sole plate.

7. The golf club as defined in claim 1 wherein said plate means is a face plate.

8. The golf club as defined in claim 1, wherein the external surface of each sleeve is threaded to retain the sleeve in said cavity, and the outer end of each sleeve includes engagement means for facilitating rotational advancement of the sleeve into the cavity.
