Abstract
Abstract A golf club putter comprising a putter head having a planar striking face, a straight upper edge and a shaft extending upwardly from the upper edge at about midpoint, substantially normal thereto, and set back from the plane of the striking face. The longitudinal axis of the shaft is substantially parallel to the plane of the striking face of the club head. The bottom edge of the club head includes a flat sole portion extending from the heel toward the toe to an intermediate location, at the same time diverging downwardly away from the upper edge of the club head. The angle of diversion is such that when the sole of the club head is flat on the ground in a horizontal position, the club shaft diverges from the vertical by ten degrees or more. The shaft is relatively short, of a preselected length to reach about knee-high of each golfer for whom the club is made when its head is resting on the ground and the golfer is standing upright. Appropriate shaft lengths range from ten to twenty-six inches depending on the height of the various golfers for whom such club is to be made. The bottom edge of the club head includes a second edge portion which extends from the termination of the flat sole portion at said intermediate location in an upwardly direction toward the toe of the club head.

Claim 1
Independent Claim
390 words
A golf club for use as a putter comprising a club head and a club shaft connected thereto, said club head including a heel portion at one side edge thereof, a toe portion at the opposite side edge thereof, a flat sole portion along a bottom edge thereof extending from said heel portion toward said toe portion and terminating at an intermediate point between said heel portion and said toe portion, a planar striking surface on said club head between said heel portion and said toe portion and above said sole portion, said flat sole portion of said club head having a planar surface which is substantially normal to said planar striking surface, a reference line above said flat sole portion and parallel to its said bottom edge a distance of five eights of an inch, said reference line being horizontal to the ground when said flat sole portion is lying flat on the ground, the longitudinal axis of said club shaft connected to said club head diverging from the vertical by at least ten degrees in relation to said horizontal reference line when said sole portion of said club head is lying flat on the ground, said club shaft being connected to said club head at substantially the midpoint of said club head between said heel portion and said toe portion, said club shaft extending in a substantially straight line from said club head to the outer free end of said club shaft, said planar striking surface of said club head lies in a first plane, said longitudinal axis of said club shaft lies in a second plane, said second plane being substantially parallel to said first plane, said club head including a back portion extending between said opposite side edges thereof, said back portion being spaced apart from said striking surface of said club head a distance which is less than the lateral distance across said club head between said heel portion and said toe portion, wherein the lower edge of said club head includes a laterally sloping edge extending laterally from said sole portion at said intermediate termination point upwardly and laterally therefrom to said toe portion of said club head, the upper edge of said club head extending at a fixed substantially right angle to said longitudinal axis of said club shaft on both sides thereof.
