Abstract
Abstract A golf putter is disclosed which includes a shaft, a grip, a hosel and a head. The head is elongated and substantially cylindrical in shape and includes a cavity which is cylindrical and elongated. The cavity is disposed toward the top of the head, thereby lowering the center of gravity of the head. The front of the head is flattened, thereby providing a surface to strike the golf ball and also moving the center of gravity of the head towards the back of the head to improve the ball control. This golf putter imparts true overspin on a golf ball.

Claim 1
Independent Claim
112 words
A golf putter for putting a golf ball on a golf surface, said golf putter comprising a shaft, a grip and a head, said head having cylindrical top and bottom surfaces, and a horizontal center line midway between said top and said bottom surfaces, and said head further including a cavity, said cavity having a top, wherein said horizontal center line passes through said cavity and the majority of the volume of said cavity is disposed above said horizontal center line so that the center of gravity of the head is located below said horizontal center line, and wherein the top of said head extends over the full length of said cavity.
Claim 2
Dependent Claim
112 words
A golf putter for putting a golf ball on a golf surface, said golf putter comprising a shaft, a grip and a head, said head having cylindrical top and bottom surfaces, and a horizontal center line midway between said top and said bottom surfaces, and said head further including a cavity, said cavity having a top, wherein said horizontal center line passes through said cavity and the majority of the volume of said cavity is disposed above said horizontal center line so that the center of gravity of the head is located below said horizontal center line, and wherein the top of said head extends over the full length of said cavity.
Claim 3
Dependent Claim
61 words
The golf putter of claim 1 wherein said head is elongated and has a first end and a second end, and said head further includes a vertical middle plane midway between said ends and wherein said vertical middle plane bisects said cavity, and wherein the cavity is substantially cylindrical and includes an opening at both of said ends of said head.
Claim 4
Dependent Claim
55 words
The golf putter of claim 2 wherein said head is substantially cylindrical in shape and includes a rear surface being rounded and a front surface being flattened thereby providing a surface for striking a golf ball and also further moving the center of gravity towards said rear surface of said head to improve ball control.
Claim 5
Independent Claim
180 words
The method of striking a golf ball with a golf putter, wherein said golf putter comprises a shaft, a grip and a head, said head having a top, a bottom and a horizontal center line midway between said top and said bottom, and said head further including a cavity, said cavity having a top, wherein said horizontal center line passes through said cavity and the majority of the volume of said cavity is disposed above said horizontal center line, thereby lowering the center of gravity of the head below said horizontal center line, and wherein the top of said head extends over the full length of the cavity and wherein the cavity is substantially cylindrical and includes an opening at both ends of said head, and wherein said head is substantially cylindrical in shape and includes a flat front surface, which method comprises the steps of: (a) gripping the golf putter at the shaft; and (b) striking a golf ball with the front surface of said head, wherein said cavity is substantially empty when said head strikes the golf ball.
Claim 6
Independent Claim
