Abstract
Abstract A golf club putter of the type having a golf shaft extending upward from the putter head comprising a translucent or transparent see-through solid putter head having peripheral outer vertical surfaces consisting of a forward putting face squared with a pair of spaced parallel side surfaces and opposite a rear surface. The forward and rearward vertical surfaces are opacified surfaces or all four vertical surfaces can be opacified. The vertical opacified surfaces are visible to a golfer looking downward at the putter head prior to putting and conveys information to the golfer of the extent of misalignment of the face of the putter with the golfball and the cup and degree of squaring with a centerline through the cup, the golfball, and the putter face.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A golf club putter comprising a putter head and an upwardly extending shaft secured to the putter head, comprising: said putter head being a translucent solid parallelogram shaped block having vertically disposed outer surfaces consisting of a front putting surface, a parallel rearward surface, and two intervening side surfaces disposed between said forward and said rearward surfaces, said outer surfaces being opacified surfaces adapted to provide visible alignment means for squaring alignment of said putter head with said cup wherein said opacified surfaces are not visible from a viewing point on a viewing line perpendicular to said putter head and intersecting the centroid of said putter head.
Claim 2
Dependent Claim
107 words
A golf club putter comprising a putter head and an upwardly extending shaft secured to the putter head, comprising: said putter head being a translucent solid parallelogram shaped block having vertically disposed outer surfaces consisting of a front putting surface, a parallel rearward surface, and two intervening side surfaces disposed between said forward and said rearward surfaces, said outer surfaces being opacified surfaces adapted to provide visible alignment means for squaring alignment of said putter head with said cup wherein said opacified surfaces are not visible from a viewing point on a viewing line perpendicular to said putter head and intersecting the centroid of said putter head.
Claim 3
Independent Claim
132 words
A method of aligning a golf putter head of a golf club putter, wherein said putter head is a translucent solid having substantially vertical sides consisting of forward putting surface, two side surfaces, and a rearward surface, said vertical surfaces being opacified surfaces for visually aligning the putting surface with the cup, the method comprising: squaring the front putting face surface of the putting head with the cup in a manner wherein the putting face is essentially perpendicular with a centerline bisecting the cup, the golf ball, and the putting face; and maintaining said putting face in a squared position while aligning the putter head so that said opacified surfaces are no longer substantially visible from a viewing point disposed on a viewing line coinciding with the centroid of the putter head.
Claim 4
Independent Claim
132 words
A method of aligning a golf putter head of a golf club putter, wherein said putter head is a translucent solid having substantially vertical sides consisting of forward putting surface, two side surfaces, and a rearward surface, said vertical surfaces being opacified surfaces for visually aligning the putting surface with the cup, the method comprising: squaring the front putting face surface of the putting head with the cup in a manner wherein the putting face is essentially perpendicular with a centerline bisecting the cup, the golf ball, and the putting face; and maintaining said putting face in a squared position while aligning the putter head so that said opacified surfaces are no longer substantially visible from a viewing point disposed on a viewing line coinciding with the centroid of the putter head.
