Abstract
Abstract This specification discloses a golf putter having a head comprising three components. These are a main body, a face plate and a sole plate. The body has a rear surface that is a segment of a cylinder having a diameter substantially the same as that of a standard putting green cup. The body has a stepped front face into which opens a recess defined by a segment of a cylindrical surface of a diameter substantially the same as that of a standard golf ball. A plane bisecting the rear and recess surfaces passes through their centers and the sweet spot on the face plate.

Claim 1
Independent Claim
305 words
In a golf putter, a head comprising: a. a main solid body portion having an undersurface, a top surface, a rear segmental, cylindrical surface extending between said top and under surfaces and defined by a diameter substantially the same as that of a standard putting green cup, a pair of spaced substantially flat, coplanar face sections between which opens a recess defined by a segmental, cylindrical surface of a diameter substantially the same as that of a standard golf ball, a flange extending forwardly of each of said face sections and presenting a shoulder overhanging each of said sections, the top surface of said flanges being an extension of said top surface of said body portion, and a hosel integrally joined to said body at the top surface thereof; b. an elongated substantially flat face plate having a finished front face with a sweet spot and a rear flat surface, a pair of wings, each of said wings having a top edge surface which engages said overhanging shoulders, said rear flat surfaces of each wing being in face-to-face engagement with said face sections, and a central portion upwardly extending from said top edge surfaces and upwardly extending between said flanges and being flush with the side surfaces of said flanges, said face plate and the front surfaces of said flanges being substantially coplanar and forming the front face of said putter; c. a sole plate having a rear segmental, cylindrical surface of the same diameter as that of the rear surface of the body with which it aligns and a straight front edge surface below said face sections, and d. means securing said body portion, face plate and sole plate in assembled relation, said body and face plate being related so that a vertical plane bisecting said segmental, cylindrical surfaces passes through said sweet spot.
