  • Patent number: 5228688
    Abstract: A set of clubs which includes a first set of woods and a second set of irons. The iron set includes multiple subsets which have a common club head which is the same in weight, vertical face height and length, but different in loft angle and face width so that all the irons have the same face presentation. The clubs of each subset have the same shaft length, but different lengths from subset to subset. Each club has a common grip line and top grip line defining a common grip about which all of the irons and woods are gripped. This provides the same vertical hand height and a common stance and swing. Counterweights are disposed in spaces to increase club head speed and each subset has a different shaft length, total weight and counterweight and the same club head weight and swing weight. The wood set has the same grip line, swing weight and vertical hand height, but different loft angles, lengths and counterweights.

  • Patent number: 4971321
    Abstract: A set of golf clubs is disclosed which includes a first set (A) of woods and a second set (B) of irons. Iron set (B) includes multiple subsets (1, 2, and 3). All of the irons in set (B) have a common club head (C) which is the same in size and shape, weight, and mass, but different in loft angle. All of the subsets are different in shaft length, but within each subset, the shaft lengths are the same. Regardless in the difference in shaft lengths, there is a common grip line (30) about which all of the irons are gripped. This provides a common stance and swing for all of the irons in set (B). Counterweights (32 and 34) disposed within spaces (X1 and X2) increase the speed of club head (C) for the irons in subsets (1 and 2), respectively. All subsets have a different shaft length, total weight, lie angle, and counterweight. All subsets have the same club head weight and swing weight.
