Abstract
Abstract A rotatable horizontal sighting ring at the upper end of a vertical support post has a ball/club path marker extending thereacross and outwardly therefrom and a clubhead alignment marker extending transversly across the sight ring to form a cross hair sight at the center of the ring. A smaller ball sight ring approximately the same diameter as a golf ball is disposed within the larger sighting ring at one side of the clubhead alignment marker. In use, the larger sighting ring is positioned such that when viewed by a golfer in a standing position, the smaller ball sight ring is superposed over the golf ball and the ball/club path marker is aligned with the desired ball path and the clubhead alignment marker will be perpendicular to the desired golf ball path. A lower ball alignment member may also be installed on the lower end of the post vertically below the sighting ring or used separately. The lower ball alignment member has lower clubhead alignment marker extending outwardly from the post, an arcuate ball receptacle at one side of the lower clubhead alignment marker, and a lower ball/club path marker extending rearwardly from the arcuate receptacle at a right angle to the lower clubhead alignment marker. The lower ball alignment member is positioned with its ball/club path marker forming an extension of the desired ball path and the cross hair sight of the upper sight ring is positioned such that the upper and lower ball/club path markers and upper and lower clubhead alignment markers are superposed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
A golf putting aid for practicing a proper putting technique comprising; a support post having an upper and lower end adapted at one end to be positioned in an upright vertical position, a sighting member on the upper end of said support post and having a circular aperture approximately the same diameter as the target hole with an upper ball/club path marker extending diametrically across said circular aperture and outwardly a distance from said circular aperture and an upper clubhead alignment marker extending diametrically across said aperture perpendicular thereto to form a cross hair sight at the center of said circular aperture, and a circular ball sight member within said circular aperture at one side of said upper clubhead alignment marker and having approximately the same diameter as a golf ball, said upper ball/club path marker extending through the center of said circular ball sight member, said sighting member capable of being positioned such that when viewed by a golfer from a standing position said upper ball/club path marker will be superposed above a desired ball path, said circular ball sight member will be superposed over the golf ball, and said upper clubhead alignment marker will be superposed above the rear of the golf ball.
Claim 2
Dependent Claim
205 words
A golf putting aid for practicing a proper putting technique comprising; a support post having an upper and lower end adapted at one end to be positioned in an upright vertical position, a sighting member on the upper end of said support post and having a circular aperture approximately the same diameter as the target hole with an upper ball/club path marker extending diametrically across said circular aperture and outwardly a distance from said circular aperture and an upper clubhead alignment marker extending diametrically across said aperture perpendicular thereto to form a cross hair sight at the center of said circular aperture, and a circular ball sight member within said circular aperture at one side of said upper clubhead alignment marker and having approximately the same diameter as a golf ball, said upper ball/club path marker extending through the center of said circular ball sight member, said sighting member capable of being positioned such that when viewed by a golfer from a standing position said upper ball/club path marker will be superposed above a desired ball path, said circular ball sight member will be superposed over the golf ball, and said upper clubhead alignment marker will be superposed above the rear of the golf ball.
Claim 3
Dependent Claim
39 words
A golf putting aid according to claim 1 in which said support post has a pointed ground penetrating extension at one end with a longitudinal portion configured to prevent rotation of said support post when placed in the ground.
Claim 4
Dependent Claim
120 words
A golf putting aid according to claim 1 in which said sighting means comprises a collar member slidably engaged on said support post and having an arm extending horizontally outwardly therefrom, a flat ring at the outer end of said arm having an inside diameter approximately the same as the diameter of a regulation golf hole cup, a first wire extending diametrically across the center of said flat ring and the ends thereof terminating a distance outwardly from said flat ring and defining an upper club path marker, and a second wire extending diametrically across the center of said flat ring perpendicular to said first wire and defining an upper clubhead alignment marker perpendicular to the upper club path marker.
Claim 5
Dependent Claim
29 words
A golf putting aid according to claim 3 in which said circular ball sight member is a smaller flat ring and said first wire passes through the center thereof.
Claim 6
Dependent Claim
214 words
A golf putting aid according to claim 1 in which said sighting means comprises a collar member slidably engaged on said support post and having an arm extending horizontally outwardly therefrom, a first flat ring at the outer end of said arm having an inside diameter approximately the same as the diameter of a regulation golf hole cup and a series of calibration lines on the top surface of said first flat ring, a second flat ring slidably mounted within said first flat ring and being rotatable relative thereto, a first wire extending diametrically across the center of said second flat ring and the ends thereof terminating a distance outwardly from said first flat ring and defining an upper club path marker, and a crossmember extending diametrically across the center of said second flat ring perpendicular to said first wire and bearing a straight line defining an upper clubhead alignment marker perpendicular to the upper club path marker, said straight line capable of being selectively positioned adjacent said calibration lines upon rotation of said second flat ring to represent the distance in fractions of an inch the path of the ball will be above or below the center of an imaginary line when the ball is putter from a predetermined distance from the target.
Claim 7
Dependent Claim
125 words
A golf putting aid according to claim 1 including; ball alignment means on the lower end of said support post spaced vertically below said sighting member and having a golf ball receptacle with a lower ball/club path marker extending axially from said golf ball receptacle and a lower clubhead alignment marker perpendicular thereto, said ball alignment member capable of being positioned with said lower ball/club path marker forming an extension of a desired ball path and said sighting member being positioned such that when viewed by a golfer from a standing position said upper and lower ball/club path markers will be superposed, said upper and lower clubhead alignment markers will be superposed, and said circular ball sight member will be superposed over the golf ball.
Claim 8
Dependent Claim
145 words
A golf putting aid according to claim 6 in which said ball alignment means comprises a collar slidably and rotatably engaged on said support post and having a first rigid wire extending horizontally outwardly therefrom, an arcuate C-shaped member secured to the outer end of said first rigid wire with the open portion of the C-shape positioned at a right angle to said first rigid wire for receiving a golf ball, and a second rigid wire extending from the closed portion of the C-shape perpendicular to said first rigid wire and in axial alignment with the center axis of the C-shape and defining said lower club path marker, the center axis of said C-shape and said second rigid wire forming an extension of a desired ball path and said first rigid wire defining said lower clubhead alignment marker being perpendicular to the desired ball path.
Claim 9
Dependent Claim
