Abstract
Abstract A putter having a first given width marking lengthwise bisected by a first vertical plane coincident with the center of gravity of the putter; a second marking arranged parallel to the first marking and having a width in excess of the given width; and a sighting guide arranged to lie within a second vertical plane disposed parallel to the first plane and intersecting the second marking, whereby a golfer using the putter can vertically position his eyes in vertical alignment with the first marking by viewing the second marking across the sighting guide and observing when the width of a viewed portion of the second marking corresponds to the given width. The putter may include additional markings/sighting guides to facilitate accurate positioning of the golfer''s eyes in a direction lengthwise of the first marking.

Total Claims: 7
Claim 1
Independent Claim
334 words
In a golf club of the type including a shaft and a putter head connected to a lower end of said shaft, said putter head having a marking on an upper surface thereof disposed in an essentially right angular relationship to an upstanding ball striking surface thereof for visually indicating to a golfer looking downwardly on said upper surface while using said club alignment of said ball striking surface with a golf ball to be struck in the direction of swing of said club, said marking being of a given width measured in a direction lengthwise of said upper surface between toe and heel end portions of said putter head and being generally horizontally disposed when viewed by said golfer looking downwardly on said upper surface, the improvement for facilitating positioning of an eye of said golfer in vertical alignment with said marking in a direction extending at right angles to said marking and lengthwise of said upper surface between said toe and heel end portions, which comprises in combination: an other marking placed on said putter head and arranged in a parallel horizontally spaced relationship relative to said first marking, said other marking having a widthwise dimension greater than said given width of said marking measured in a direction lengthwise of said upper surface and being generally horizontally disposed when viewed by said golfer looking downwardly on said upper surface; and a sighting guide carried on said putter head, said sighting guide including a generally sharpened sighting edge disposed in vertical alignment above and in relatively close proximity with said other marking, and said sighting edge being disposed in an essentially parallel relationship relative to said marking and said other marking, whereby said golfer can position an eye in vertical alignment with said marking in a direction lengthwise of said upper surface by viewing said other marking across said sighting edge and observing when the width of a viewed portion of said other marking is essentially equal to the width of said marking.

Dependent Claim
334 words
In a golf club of the type including a shaft and a putter head connected to a lower end of said shaft, said putter head having a marking on an upper surface thereof disposed in an essentially right angular relationship to an upstanding ball striking surface thereof for visually indicating to a golfer looking downwardly on said upper surface while using said club alignment of said ball striking surface with a golf ball to be struck in the direction of swing of said club, said marking being of a given width measured in a direction lengthwise of said upper surface between toe and heel end portions of said putter head and being generally horizontally disposed when viewed by said golfer looking downwardly on said upper surface, the improvement for facilitating positioning of an eye of said golfer in vertical alignment with said marking in a direction extending at right angles to said marking and lengthwise of said upper surface between said toe and heel end portions, which comprises in combination: an other marking placed on said putter head and arranged in a parallel horizontally spaced relationship relative to said first marking, said other marking having a widthwise dimension greater than said given width of said marking measured in a direction lengthwise of said upper surface and being generally horizontally disposed when viewed by said golfer looking downwardly on said upper surface; and a sighting guide carried on said putter head, said sighting guide including a generally sharpened sighting edge disposed in vertical alignment above and in relatively close proximity with said other marking, and said sighting edge being disposed in an essentially parallel relationship relative to said marking and said other marking, whereby said golfer can position an eye in vertical alignment with said marking in a direction lengthwise of said upper surface by viewing said other marking across said sighting edge and observing when the width of a viewed portion of said other marking is essentially equal to the width of said marking.
Claim 3
Dependent Claim
70 words
The improvement according to claim 1, wherein said putter head includes an integrally formed connector arranged to upstand from adjacent said heel end portion for connecting said putter head to said lower end of said shaft, said other marking is disposed on said upper surface intermediate said marking and said connector to lie in an essentially coplaner relationship with said marking, and said sighting edge is defined by said connector.
Claim 4
Dependent Claim
116 words
The improvement according to claim 2, wherein said sighting guide additionally defines a pair of parallel additional generally sharpened sighting edges, said additional sighting edges extending in a direction towards said heel end portion from adjacent opposite ends of said sighting edge and being disposed above and essentially parallel to said upper surface, a pair of additional markings are placed on said upper surface of said putter head and arranged in an essentially coplaner relationship with said other marking to extend in a direction towards said heel end portion from adjacent opposite ends of said other marking, and said additional markings are arranged one below and in vertical alignment with each of said additional sighting edges.
Claim 5
Dependent Claim
113 words
The improvement according to claim 1, wherein said sighting guide is cut away to define a vertically extending sighting notch disposed essentially perpendicular to said sighting edge and opening outwardly therethrough, said sighting notch being bisected by a vertical plane arranged essentially perpendicular to said marking and intersecting same at a point intermediate front and rear ends thereof relative to said direction of swing, and an additional portion of said other marking extending at right angles to said viewed portion is viewable through said notch at least when said golfer using said club has an eye in substantial vertical alignment with said point in a direction measured between said ends of said marking.
Claim 6
Dependent Claim
32 words
The improvement according to claim 1, wherein said other marking is arranged vertically below said upper surface, and said sighting guide and said other marking are defined by said toe end portion.
Claim 7
Dependent Claim
117 words
The improvement according to claim 5, wherein said sighting guide additionally defines a pair of parallel additional generally sharpened sighting edges, said additional sighting edges extending in a direction towards said heel end portion from adjacent opposite ends of said sighting edge and being formed in part by said upper surface, a pair of additional markings are placed below and parallel to said upper surface of said putter head and arranged in an essentially coplaner relationship with said other marking to extend in a direction towards said heel end portion from adjacent opposite ends of said other marking, and said additional markings are arranged one below and in vertical alignment with each of said additional sighting edges.
