Abstract
Abstract A golf club has a clubhead upon which is rotatably mounted a rotary member or roller. The roller is exposed at the front of the club to engage the golf ball and is free to rotate upon a horizontal axis while in contact with the golf ball to facilitate rotation of the golf ball as the club moves the golf ball across the ground. The clubhead preferably has a front face that is directed toward the ball and the roller is mounted on the clubhead as a part of the front face of the club so as to engage the ball and to rotate freely while in contact with the ball. Typically, the clubhead has a pair of horizontally spaced apart supporting walls with an opening between them to accommodate the roller and to support the roller for rotation about a horizontal axis with the roller located at an elevation adapted to engage the center of the ball but to be held out of contact with the ground.

Independent Claim
177 words
A golf club comprising, a clubhead, a rotary member supported on the clubhead and including a movable surface, said rotary member is mounted with the movable surface thereof exposed at a front portion of said club to engage a golf ball, said rotary member is free to rotate upon an axis at the center of the rotary member while in contact with the ball to facilitate rotation of the ball as the club moves the ball across the ground, the clubhead has a lower portion that extends below the rotary member to hold the rotary member out of contact with the ground when the ball is struck, the lower portion of the clubhead is positioned to prevent the ground from causing the rotary member to rotate during use so that the ball and rotary member are able to roll freely in opposite directions as the ball is moved across the ground by the rotary member even if the clubhead strikes the ground, and rotation of the rotary member reduces frictional engagement between the roller and the ball.
