Abstract
Abstract A substantially T-shaped putter type golf club including a shaft and a generally flat striking face disposed perpendicularly to a longitudinally body portion within which extends a bore that houses a plurality of weighted balls arranged in diametrically abutting relation such that a transfer of kinetic energy from the weighted balls to a golf ball upon impact drives the golf ball in the same direction as the alignment of the weighted balls.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A golf putter comprising, in combination: a member substantially T-shaped in plan view having a longitudinal body portion and a transverse head portion and having a shaft connected, thereto, and extending angularly upwardly, therefrom; a generally flat face on the transverse head portion disposed perpendicular to said longitudinal body portion and facing in the direction of an intended putt; a bore extending longitudinally within the body portion and perpendicular to said face and aligned with the direction of an intended putt; and a plurality of weighted balls arranged longitudinally in diametrically abutting relation and disposed within said bore and formed of a material having a greater density than the density of said member whereby during a putt a transfer of kinetic energy from said weighted balls collectively being swung in the direction of an intended putt to a golf ball substantially aligned with said weighted balls drives the golf ball in the same direction as the alignment of the weighted balls.
Claim 2
Dependent Claim
161 words
A golf putter comprising, in combination: a member substantially T-shaped in plan view having a longitudinal body portion and a transverse head portion and having a shaft connected, thereto, and extending angularly upwardly, therefrom; a generally flat face on the transverse head portion disposed perpendicular to said longitudinal body portion and facing in the direction of an intended putt; a bore extending longitudinally within the body portion and perpendicular to said face and aligned with the direction of an intended putt; and a plurality of weighted balls arranged longitudinally in diametrically abutting relation and disposed within said bore and formed of a material having a greater density than the density of said member whereby during a putt a transfer of kinetic energy from said weighted balls collectively being swung in the direction of an intended putt to a golf ball substantially aligned with said weighted balls drives the golf ball in the same direction as the alignment of the weighted balls.
Claim 3
Dependent Claim
19 words
The invention defined by claim 1 wherein said bore extends into the head portion and terminates adjacent said face.
Claim 4
Dependent Claim
25 words
The invention defined by claim 2 wherein said balls are disposed in diametrically abutting relation and in abutting relation with opposite ends of said bore.
Claim 5
Dependent Claim
20 words
The invention defined in claim 1 wherein said face includes a ball striking portion in concentric alignment with said bore.
Claim 6
Dependent Claim
28 words
The invention defined by claim 1 wherein said bore opens through said flat face and a ball-striking member closes the end of the bore at said flat face.
Claim 7
Dependent Claim
45 words
The invention defined by claim 5 wherein means are provided for urging the ball-striking member against the plurality of balls disposed in said bore maintaining them in diametrically abutting relation and in abutting relation with such ball-striking member and the opposite end of said bore.
Claim 8
Dependent Claim
26 words
The invention defined by claim 1 wherein said shaft is connected to the transverse head portion and is offset therefrom in the direction of intended putt.
Claim 9
Dependent Claim
20 words
The invention defined by claim 1 wherein the balls have a density at least 2.5 times that of said member.
Claim 10
Dependent Claim
18 words
The invention defined by claim 1 wherein the balls are formed of steel and said member is aluminum.
