Abstract

Golf clubs of the type known as '"'"''"'"''"'"''"'"'woods,'"'"''"'"''"'"''"'"' wherein the torque resulting from striking golf balls with the clubs is reduced, wherein the length of the club head is reduced, wherein the shaft is close to the heaviest weight concentration of the club, and wherein the hitting face of the club occupies the entire front side of the club to eliminate erratic shots off a rounded heel or toe of the club, and wherein the hitting face is substantially flat in order to reduce side spin on the ball.

Claims

1. Golf club of the type referred to as a wood, comprising a horizontally disposed club head having the front side thereof completely flat to form a hitting face over its entire area whereby a golf ball may be struck at any point thereof without angular deflection of the golf ball, said hitting face having a loft angle of conventional angular inclination for a wood-type club head, one end of said club head being convexly curved backwardly and entirely inwardly of one end of said hitting face and forming the heel of the club head, the other end of said club head being convexly curved backwardly and entirely inwardly of the other end of said hitting face and forming the toe of the club head, the reverse side of said club head being thickened rearwardly and convexly curved symmetrically of the horizontal center of the club head and smoothly merging with said convex curvatures of said heel and toe in order to distribute the weight of the club head symmetrically about a vertical plane perpendicular to the center of the hitting face and to adjust the horizontal center of gravity of said club head to its horizontal center whereby said club head will be less likely to twist about vertically directed axes upon striking golf balls at random points of said hitting face, the upper and lower sides of said club head and of said hitting face being substantially parallel whereby the heel and toe portions of the club head are of substantially the same weight, a shaft having its lower end fixed to the upper side of the heel of the club head, and further having the length of said club head from the toe to heel ends being approximately 3 1/2 inches and with the maximum distance of the shaft axis to the center of the hitting face being approximately 1 1/4 inches, the convexly curved heel of the club head being angularly inclined downwardly and inwardly parallel to the shaft axis from the upper edge of the heel substantially to the lower edge of the heel and being spaced conventionally no farther than five-eighths inch from the shaft axis.

2. The combination of claim 1, said hitting face being of substantially shorter length along its lower edge than along its upper edge.
