Abstract
Abstract The universal golf putter comprises a head having a center axis of symmetry and a weight of at least ten ounces. The head is characterized by a striking face, a heel and a toe extending rearwardly from the opposite sides of the striking face and a center of gravity symmetrically located behind the striking face. A curved sole rearwardly extends from the striking face and smoothly blends at the opposite ends thereof with the heel and toe. A bridge part spans between the striking face, the heel and the toe. A shank is disposed along the center axis of symmetry. A neck couples the shank with the bridge. A shaft-receiving hosel extends upwardly from the shank and angulates therewith at an angle between 10° and 20°. The hosel is coupled to a shaft terminated in a handle. The shaft has a length less than forty inches. An alignment indicator extends in a vertical plane of symmetry.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and a toe extending rearwardly from the opposite sides of the striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe; a bridge part spanning between the striking face, the heel and the toe, said toe and said heel being weighted, whereby the center of gravity of said putter is substantially symmetrically located behind said striking face; a shank extending upwardly and being disposed along said center axis; a neck coupling said shank with said bridge part; a shaft-receiving hosel extending upwardly from said shank; said striking face, sole, heel and toe form an open recess therebetween and said recess extends over the majority surface of said striking face; and said striking face being integral and continuous with said sole and said bridge part.
Claim 2
Dependent Claim
155 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and a toe extending rearwardly from the opposite sides of the striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe; a bridge part spanning between the striking face, the heel and the toe, said toe and said heel being weighted, whereby the center of gravity of said putter is substantially symmetrically located behind said striking face; a shank extending upwardly and being disposed along said center axis; a neck coupling said shank with said bridge part; a shaft-receiving hosel extending upwardly from said shank; said striking face, sole, heel and toe form an open recess therebetween and said recess extends over the majority surface of said striking face; and said striking face being integral and continuous with said sole and said bridge part.
Claim 3
Dependent Claim
148 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and toe extending rearwardly from the opposite sides of the striking face, said toe and said heel being weighted whereby the center of gravity of said head is symmetrically located behind said striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe; a bridge part spanning between the striking face, the heel and the toe; a shank extending upwardly and being disposed along said center axis; a neck coupling said shank with said bridge part; a shaft-receiving hosel extending upwardly from said shank; a shaft coupled to said hosel and said shaft having a longitudinal axis intersecting said center axis at a point above said shank and said axes forming therebetween an angle of at least 10°.
Claim 4
Dependent Claim
148 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and toe extending rearwardly from the opposite sides of the striking face, said toe and said heel being weighted whereby the center of gravity of said head is symmetrically located behind said striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe; a bridge part spanning between the striking face, the heel and the toe; a shank extending upwardly and being disposed along said center axis; a neck coupling said shank with said bridge part; a shaft-receiving hosel extending upwardly from said shank; a shaft coupled to said hosel and said shaft having a longitudinal axis intersecting said center axis at a point above said shank and said axes forming therebetween an angle of at least 10°.
Claim 5
Dependent Claim
205 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and a toe extending rearwardly from the opposite sides of the striking face, said toe and said heel being weighted whereby the center of gravity is symmetrically located behind said striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe, said striking face, sole, heel and toe forming an open recess therebetween and said recess extending over most of the surface of said striking face; a bridge part spanning between the striking face, the heel and the toe, and said striking face being integral and continuous with said sole and said bridge part; a shank extending upwardly and being disposed in a substantially longitudinal plane which bisects said sole; a neck coupling said shank with said bridge part; said neck having a cross-sectional area which decreases gradually from said bridge part and blends smoothly with said shank; a shaft-receiving hozzle extending upwardly from said shank; and a shaft coupled to said hozzle, the longitudinal axis of said shaft intersecting said center axis at a point above said shank and forming an acute angle therewith.
Claim 6
Dependent Claim
205 words
A golf putter head having a center axis of symmetry, said head defining a ball-striking face; a heel and a toe extending rearwardly from the opposite sides of the striking face, said toe and said heel being weighted whereby the center of gravity is symmetrically located behind said striking face; a sole having a curved surface extending rearwardly from the striking face and forming integral part with the heel and toe, said striking face, sole, heel and toe forming an open recess therebetween and said recess extending over most of the surface of said striking face; a bridge part spanning between the striking face, the heel and the toe, and said striking face being integral and continuous with said sole and said bridge part; a shank extending upwardly and being disposed in a substantially longitudinal plane which bisects said sole; a neck coupling said shank with said bridge part; said neck having a cross-sectional area which decreases gradually from said bridge part and blends smoothly with said shank; a shaft-receiving hozzle extending upwardly from said shank; and a shaft coupled to said hozzle, the longitudinal axis of said shaft intersecting said center axis at a point above said shank and forming an acute angle therewith.
