Abstract

An improved head for a golf putter having a weight receiving member elevated above the sole of the putter head to raise the vertical center of gravity of the putter head. The weight receiving member has apertures at the toe and heel ends which are adapted to removably retain weights weighing various predetermined amounts, preferably weighted bolts which have slots adapted for operation by a coin.

Claims

1. A head for a golf putter, comprising:

a sole member having a substantially flat sole surface, said sole surface having front edge and a rearward edge defining a sole depth;

an elongated face member with a substantially flat face surface and having a front end and a back end, the distance from said front end to said back end defining a face length, said face surface having a sole edge and an upper edge defining a face height of said face surface, said face member attached at said sole surface to said front edge at substantially right angles;

an elongated weight receiving member having a heel aperture at a heel end a toe at a toe end, and a center of gravity, said apertures extending axially inwardly; and

support means attached to said face member on a surface other than said face surface for supporting said weight receiving member substantially parallel to said sole surface and supporting the center of gravity of said weight receiving member above said sole surface by a weight height, approximately centered between said toe and said heel of said face member, wherein said weight height is approximately equal to the radius of a regulation golf ball.

2. A head for a golf putter, according to claim 1, wherein:

said support means comprises first and second support members attached to said face member and to said weight receiving member.

3. A head for a golf putter, according to claim 2, wherein said first support member has a first weight support aperture and said second support member has a second weight support aperture and said weight receiving member passes through and is supported by said weight support apertures.

4. A head for a golf putter, according to claim 1, wherein said support means also is attached to said sole member.

5. A head for a golf putter, according to claim 4, further comprising a neck adapted for receiving a shaft of a golf club, attached to said face member near said heel.

6. A head for a golf putter, according to claim 1, wherein said face height is less than the diameter of a regulation golf ball.

7. A head for a golf putter, according to claim 6, wherein said sole depth is less than the diameter of a regulation golf ball.

8. A head for a golf putter, according to claim 1, further comprising to toe weight removably retained in said toe aperture and a heel weight removably retained in said heel aperture.

9. A head for a golf putter, according to claim 8, wherein said toe weight and said heel weight are selected from a plurality of toe weights and heel weights weighing various predetermined amounts.

10. A head for a golf putter, according to claim 9, wherein said toe aperture and said heel aperture are provided with threads and said toe weights and heel weights comprise weighted bolts adapted for threading into said toe aperture and said heel aperture.

11. A head for a golf putter, according to claim 10, wherein said bolts have slots adapted for insertion of a coin, whereby said bolts can be rotated by inserting a coin in said slots and rotating said coin.

12. A head for a golf putter, according to claim 11, further comprising flexible and compressible washers mounted on said weight bolts.

13. A head for a golf putter, according to claim 2, wherein said weight receiving member comprises a cylinder.

14. A head for a golf putter, according to claim 2, wherein said face member is substantially planar.

15. A head for a golf putter, according to claim 14, wherein said sole member is substantially planar.

16. A head for a golf putter, according to claim 15, wherein said sole surface is slightly convex away from said face.

17. A head for a golf putter, according to claim 1, wherein said face member and said sole member are integrally formed.

18. A head for a golf putter, according to claim 1, wherein said face member, said sole member and said support members comprise metal.

19. A head for a golf putter, according to claim 1, wherein said sole has a length approximately equal to said face length.

20. A head for a golf putter, according to claim 19, wherein said support means positions the center of gravity of said weight receiving member away from said face towards said rearward edge approximately a length equal to the raduis of a regulation golf ball.

21. A head for a golf putter, comprising:

a substantially planar, slightly convex sole having a front edge and a rearward edge defining a sole depth of said sole, said sole depth being approximately equal to the raduis of a regulation a golf ball;

a substantially planar face having a face surface, a sole edge and an upper edge defining a face height of said face surface, a front end and a back end, attached at said sole edge to said front edge at substantially right angles, whereby said face surface and said sole surface define an angle of approximately 87°

;

a first weight cylinder support having a first weight support aperture attached to said face adjacent to a toe portion and attached to said sole;

a second weight cylinder support having a second weight support aperture attached to said face adjacent to a heel portion and attached to said sole;

a weight cylinder having a center of gravity and a threaded weight receiving bore with a toe end and a heel end passing through and supported by said weight cylinder supports, whereby the center of gravity of said weight cylinder is supported above said sole approximately a distance equal to the raduis of a regulation golf ball, and is approximately centered between said front end and said back end of said face;

a threaded weighted toe bolt having a slot adapted for insertion of a coin threadingly engaged in said toe end of said weight receiving bore; and

a threaded weighted heel bolt having a slot adapted for insertion of a coin threadingly engaged in said heel end of said weight receiving bore;

wherein said toe bolt and said heel bolt are selected from a plurality of toe weights and heel weights weighing various predetermined amounts.
