Golf club with bulge radius and increased moment of inertia about an inclined axis
First Claim
1. A wood-type golf club comprising a clubhead and a shaft attached to the clubhead, the clubhead comprising a body having a toe portion and a heel portion, a top surface, a sole surface, and a striking face extending between the top and sole surfaces, the striking face having a convex curvature about a first axis which extends parallel to a second axis which extends through the center of gravity of the clubhead, said first and second axes lying in a plane which extends through the center of the striking face and which intersects the centerline of the shaft above the clubhead.

Abstract
A golf clubhead has weight distributed on opposite sides of a non-vertical axis which extends through the center of gravity of the clubhead in a plane which intersects the axis of the shaft above the clubhead to provide more accurate off-center hits. Wooden clubs are provided with bulge and roll which curve, respectively, about said axis and an axis perpendicular thereto. The radius of the roll is increased to make the loft of the club substantially uniform from top to bottom.

- 10. A wood-type golf club comprising a clubhead and a shaft attached to the clubhead, the clubhead comprising a body having a toe portion and a heel portion, a top surface, a sole surface, and a striking face extending between the top and sole surfaces, the striking face having a convex roll curvature about a first axis which extends parallel to a second axis which extends through the center of gravity of the clubhead, said first and second axes lying in a first plane which extends through the center of gravity of the clubhead and which is perpendicular to a second plane which is tangent to the center of the striking face, said first axis being about 16 inches behind the striking face whereby the radius of said roll curvature is about 16 inches.
