Abstract
Abstract A golf ball putter wherein the mass of the putter head is distributed along the line of swing or stroke of the putter as distinguished from distribution of the mass of the putter head transversely to the line of the stroke of the club, the shaft being connected to the head at a point centrally of the length and width of the head, the head having a striking face defined by a transversely extending web which projects laterally of the main body of the head, the principal mass of the putter head being confined to said main body, the lateral extent of the striking face relative to the main body being such that a golf ball is engaged by a "sweet spot" throughout a major transverse extent of the striking surface, the head being provided with a cavity for weighted elements such as shot held in place by a matrix, and the cavity being closed by a rectangular panel extending longitudinally of the lie of stroke of the putter in a direction normal to the striking face and comprising an aiming stripe.

Claim 1
Independent Claim
203 words
A golf ball putter comprising: a shaft, a club head having a primary body portion and a striking face extending laterally from said body portion at the front and rear therof, said body portin being elongated longitudinally of the line of stroke of the putter and being longer in its longitudinal dimension than in its lateral dimension, the lateral dimension of said body portion being a substantial portion of the lateral dimension of said club head, said body portion having its mass extending in its longitudinal directin and concentrated behind medial portions of said striking faces and inwardly from both ends of said striking faces, said body portion having its center of gravity located at the longitudinal and lateral center of said club head, each of said striking faces having a medial portion coextensive with the lateral dimension of said body portion and possessing coplanar extensions defined by free ending webs located laterally beyond said body portion in opposite directions and being of equal length thereby forming with said body portion a club head shaped in the form of a symmetrical `letter` "H", and said shaft having its lower end conected at a point on a line vertically above said center of gravity.
Claim 2
Dependent Claim
