Filed:

May 18, 2000

Appl. No.:

09/574177

Inventors:

Richard C. Card - Dallas TX 75230
Mark C. Myrhum - Phoenix AZ 85050-8802

International Classification:

A63B 5304

US Classification:

473340, 473329, 473342

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 driver club and a method for making a golf driver club comprising the steps of: applying a curable coating composition comprising polytetrafluoroethylene to exterior surfaces of a driver head to provide a wet coated driver head; drying the wet coated club driver head by heating at elevated temperatures of from about 350. degree. F. to about 400. degree. F. for from about 4 to about 10 minutes to provide a dried driver head; curing the dried driver head by heating at an elevated temperature of from about 790. degree. F. to about 820. degree. F. for a period of from about 4 to 8 minutes, and thereafter, heating at a temperature of from about 700. degree. F. to about 800. degree. F. for a period of from about 10 to about 30 minutes to provide a driver club head having a cured, firmly adherent coating disposed thereon. The coating has a thickness of from about 20 um to about 40 um, and is effective to reduce backspin of a golf ball hit with said driver club by at least about 10% fewer RPM as compared to a similar driver club not having said coating.
