Balanced golf putter
First Claim
1. A neutrally balanced golf putter which comprises:
- an elongated head having heel and toe ends, a sole and opposite tope surface and opposed striking and aft faces;
a substantially straight shaft secured to said head at an angle to a line between said heel and toe ends and at substantially the geometric centers between said heel and toe and between said faces;
a gripping means on said shaft at the shaft end opposite said head;
two spaced, non communicating chambers in said head on opposite sides of said shaft, said chambers located so that the center of mass of the entire club lies on the longitudinal axis of said shaft; and
wherein the size and spacing of said chambers is selected so that when said club is rotatably supported at two spaced points along said shaft said putter will rotate to balanced position with said head substantially horizontal.

Abstract
A golf club that produces a smoother stroke, does not attempt to turn in the golfer'"'"'s hands, and provides superior feedback to the golfer comprises a putter head, a shaft, and a grip. The putter head comprises an elongated body having a toe end, a heel end, a fore side including a ball striking face, an aft side opposite said fore side, a sole, and a top side. A longitudinal axis runs heel to toe parallel with the ball striking face. The head includes two chambers that increase the proportion of heel and toe mass relative to the center mass and decrease the transverse cross sectional area of head material and thereby increase vibration up an attached shaft upon ball impact. The chambers each exit the top side in a transverse slot. The transverse slots are approximately a ball width apart and equal distance on each side of the center of mass of said head. The entire putter is balanced so as to be more stable in a golfer'"'"'s hands. A neutrally balanced putter has no moment about the shaft axis. A face balanced putter has weight distribution such that, when the putter may freely rotate about the shaft axis, the putter will come to rest with the head longitudinal axis level.

4. The method of making a neutrally balanced golf putter which comprises the steps of:
-
providing an elongated golf putter head having heel and toe ends, a sole and opposite top surface and opposed striking and aft faces; securing a substantially straight shaft to said head at an angle to a line between said heel and toe ends and at substantially the geometric center between said heel and toe and between said faces; applying grip means to the end of said shaft opposite said head; forming two spaced, non-communicating, chambers in said head on opposite sides of said shaft, located so that the center of mass of the putter lies along the longitudinal axis of said shaft; balancing said putter at two lines spaced longitudinally along said shaft; and modifying the volume of said chambers so that said putter rotates on said balance lines to come to rest with said head lying in a substantially horizontal plane. - View Dependent Claims (5, 6)
