Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
220 words
In a golf putter having a head defining a ball striking front face, a bottom surface, a top surface, a rear surface, a heel and a toe, the improvement comprising: (a) the top surface having first, second and third regions respectively near the toe, mid-extent of the head and heel, (b) each of the first and third regions having a recess sunk downwardly therein, (c) and metallic weights received downwardly in said recesses, each recess intersecting the corresponding region top surface so that the outlines of said recesses and weights, which are substantially rectangular, in horizontal cross section, are visible from above said top surface, the recesses having bottom walls everywhere spaced above the bottom surface of the head, (d) the head defining a ledge proximate said second region, the ledge having a top surface extending generally at the levels of the lowermost portions of said weights, and including a main marker on the ledge directed toward and the front face of the head, said marker being located at the mid-point between said recesses, (e) and the head defining a forward upright wall that extends between and forwardly of said first and third regions and above their levels, the putter having a hosel integral with said wall at a location above the top levels of said first and third regions.
Claim 2
Dependent Claim
220 words
In a golf putter having a head defining a ball striking front face, a bottom surface, a top surface, a rear surface, a heel and a toe, the improvement comprising: (a) the top surface having first, second and third regions respectively near the toe, mid-extent of the head and heel, (b) each of the first and third regions having a recess sunk downwardly therein, (c) and metallic weights received downwardly in said recesses, each recess intersecting the corresponding region top surface so that the outlines of said recesses and weights, which are substantially rectangular, in horizontal cross section, are visible from above said top surface, the recesses having bottom walls everywhere spaced above the bottom surface of the head, (d) the head defining a ledge proximate said second region, the ledge having a top surface extending generally at the levels of the lowermost portions of said weights, and including a main marker on the ledge directed toward and the front face of the head, said marker being located at the mid-point between said recesses, (e) and the head defining a forward upright wall that extends between and forwardly of said first and third regions and above their levels, the putter having a hosel integral with said wall at a location above the top levels of said first and third regions.
Claim 3
Dependent Claim
33 words
The improvement of claim 1 wherein the head consists of a first metal in which said recesses are formed, and the weights consist of other metal which is denser than the first metal.
Claim 4
Dependent Claim

Claim 8
Dependent Claim
111 words
The improvement of claim 6 wherein the weights and recesses are closer to said rear surface than to said front face both weights having the same shape in a horizontal plane, the third recess having a width about equal to the diameter of a standard golf ball, the putter having a shaft intersecting the head closer to said third region than to said first region, the weight in the recess at said third region having a bottom surface spaced above the bottom surface of the recess at said third region, the mass of the weight at the third region being less than the mass of the weight at said first region.
Claim 9
Dependent Claim
