Abstract
Abstract A golf club designed for putting, comprising a club head formed of a light-transmitting material and having at least one and preferably three metallic weight members, preferably elongate, disposed transversely to the longitudinal axis of the club head. The weight members are preferably in the form of cylinders whose axis is positioned along a line perpendicular to the striking face of the club head, in the direction in which the club head will move and in the direction the ball normally should proceed. The centrally located weight member is positioned so that its axis is coincident with the ''''sweet point'''' or percussive point of the club, that is, the point at which the ball is most effectively struck. The outwardly disposed weight members are preferably so positioned that the moments of inertia of the club about the point at which the ball is struck are substantially the same. The weight members are clearly visible to the golfer through the club and he can readily determine at what point to strike the ball, and additionally can utilize the outline of the centrally located weight member for sighting the club with the ball and the hole.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
209 words
A putter golf club for use in putting comprising: a. an elongated club head symmetrically formed about a longitudinal axis and composed of a light-transmitting material having at least one relatively flat striking face extending parallel with respect to said longitudinal axis, said head having disposed therein: 1. a centrally located first weight balancing of substantially rod form arranged substantially perpendicular to said striking face having an end face exposed and flush with the surface of said striking face, and having a longitudinal surface substantially perpendicular to said striking face, 2. a second weight balancing member disposed within the toe portion of said club head, 3. a third weight balancing member disposed in the heel portion of said club head, all of said weight members being spaced apart from each other along the longitudinal direction of said club head, 4. said weight balancing members being composed of metal; and b. a handle comprising a shaft having one end fixedly attached to said head at a location between said first weight balancing member and the heel portion of the club head, and having a grip mounted at the other end of said handle, c. said light-transmitting material being effective to reveal said longitudinal surface of the first weight balancing member.
