Abstract
Abstract A golf putter having a one single alignment means at one single focal point on the clubhead to aid the user in properly positioning the club in a level plane including an alignment mark to determine the loft position of the club and an alignment mark to determine the lie position of the club. The alignment system is formed of a combination of fixed inner indicia and complementary outer indicia which are located on at least two different surfaces. The fixed inner indicia, which is the dominant central image, has at least two directional marks with one mark being parallel and the other mark being perpendicular to the ball striking face. The complementary outer indicia is vertically spaced to interface with the inner indicia to create a visual in-line extension of the dominant central image appearing as one enlarged image when the clubhead is properly soled thereby providing a single sighting image for the proper positioning of the club with respect to loft and lie.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
247 words
A golf clubhead of the putter type having a putter blade with a frontal striking face, a rear face and at least one upper surface and at least one lower surface comprising; one single visual precision alignment means creating one single sighting image at one single focal point for providing both lie and loft alignment of said clubhead including: (a) inner indicia located on one of said surfaces forming a dominant central image having at least two inner directional marks, one of said marks being parallel to said striking face and a second of said marks being perpendicular to said striking face, (b) outer indicia positioned outside of said inner indicia and located on the other of said surfaces vertically spaced from and complementary to said inner indicia, said outer indicia having at least one outer directional mark in the same linear direction as each of said two inner directional marks, one of said outer marks being parallel to said striking face and a second of said outer marks being perpendicular to said striking face, and (c) said inner indicia extend outwardly to interface with said complementary outer indicia creating a visual in-line outwardly radiating extension of said dominant central image appearing as one enlarged image when said inner indicia and said outer indicia are interfaced clearly presenting a single sighting image at one single focal point so that the user may establish precision alignment for both lie and loft indicating when the clubhead is properly soled.
Claim 2
Dependent Claim
247 words
A golf clubhead of the putter type having a putter blade with a frontal striking face, a rear face and at least one upper surface and at least one lower surface comprising; one single visual precision alignment means creating one single sighting image at one single focal point for providing both lie and loft alignment of said clubhead including: (a) inner indicia located on one of said surfaces forming a dominant central image having at least two inner directional marks, one of said marks being parallel to said striking face and a second of said marks being perpendicular to said striking face, (b) outer indicia positioned outside of said inner indicia and located on the other of said surfaces vertically spaced from and complementary to said inner indicia, said outer indicia having at least one outer directional mark in the same linear direction as each of said two inner directional marks, one of said outer marks being parallel to said striking face and a second of said outer marks being perpendicular to said striking face, and (c) said inner indicia extend outwardly to interface with said complementary outer indicia creating a visual in-line outwardly radiating extension of said dominant central image appearing as one enlarged image when said inner indicia and said outer indicia are interfaced clearly presenting a single sighting image at one single focal point so that the user may establish precision alignment for both lie and loft indicating when the clubhead is properly soled.
