Abstract

A golf putter has most of its weight in the upper half of the putter head so the hitting force against a ball is directed horizontally, reducing lift on the ball and causing the ball to roll sooner. A rectangular slot is formed through the center of the putter head, immediately behind the putter face, and is the same width as the diameter of a golf ball so the edge of the ball and the sides of the rectangular slot are integrated by the player's eye to create an alignment used to aim the ball to the hole. The putter shaft and hand grip are stiff to minimize bending action upon contact with the ball. The present grip on the shaft has a generally square cross-section, allowing for a better and consistent fit in the player's hand. The putter preferably incorporates a solid brass head, and also is designed with most of its weight in its upper half to produce a high center of gravity, while conforming to USGA rules.

Claims3

Dependent claims

A golf putter comprising a shaft with a grip at one of its ends, and a head attached to said shaft at the opposite end thereof from said grip,

said head including a body having an upper section with a wider front and narrower rear section,
a front face on said front section and depending therefrom, said face having a lower front ground engaging edge,
a pedestal depending from said rear section and having a lower rear ground engaging surface corresponding in extension from said body upper section to the lower ground engaging edge of said front face,
said central section thereby being elevated above the ground during use of the putter,
means defining a slot extending through said upper body section behind said front face and approximately equidistant from the sides of said front face, said slot corresponding in width to the diameter of a golf ball, and
said shaft being attached to said rear section and extending upward therefrom,
whereby the center of gravity of said head is near the upper surface of said head.
