Abstract

A durable wooden golf club head is disclosed having a hitting face with a non-wooden durable insert that is screw threaded into the head whereby the wooden head and face are protected from deterioration upon impact by a golf ball. The wooden head is made by screw threading the insert into a matching socket and causing a hardenable liquid adhesive to hydraulically penetrate the head from the socket to the surface of the wood whereby the head provides a solid golf ball hitting body.

Claims

1. A wooden golf club head comprising

a body of wood having a wooden hitting face with toe, central and heel face hitting areas,

at least one generally cylindrical socket formed entirely by the wood of said body extending from the surface of the wooden hitting face in any of said hitting areas into said body of wood behind said face, said socket having a counter-bored screw threaded portion for securely receiving an insert, and

a non-wooden durable generally cylindrical insert having a screw threaded end and head portion to match said socket in screw threaded securement therein, said insert head portion having an exposed surface flush with said hitting face, said insert adhesively bonded into said wood by a hardenable liquid adhesive penetrating the wood behind the face through the volume of the wooden head from the socket to the exterior surface of the wood whereby said head provides a solid golf ball hitting body attributable to the coaction of the insert bonded into said head and for protection of the wooden face against deterioration upon impact by a golf ball.

2. The golf club head of claim 1 wherein said central face hitting area is provided with a face plate secured into the wooden hitting face from the bottom to the top of the face and where said insert is secured into a socket in the toe face hitting area.

3. The golf club head of claim 1 wherein said central face hitting area is provided with a face plate secured into the wooden hitting face from the bottom to the top of the face and where said insert is secured into a socket in the heel face hitting area.

4. The golf club head of claim 1 wherein said central face hitting area is provided with a face plate secured into the wooden hitting face from the bottom to the top of the face and where said insert is secured into sockets in both the toe and heel face hitting areas.

5. The golf club head of claim 1 wherein said central face hitting area is provided with a face plate from the bottom to the top of the face secured by means of a screw threaded insert into the wooden hitting face and where said insert is secured into sockets in both the toe and heel face hitting areas.

6. The golf club head of claim 1 wherein said insert is made of fiber, plastic or metal.

7. A method of making a wooden golf club head comprising

providing a wooden golf club head having a wooden hitting face,

counter-boring a screw threaded generally cylindrical socket through said wooden face into the head,

introducing hardenable liquid adhesive into said socket to at least partially fill the socket in an amount for penetration through the volume of the head from the socket to the exterior surface of the wooden head,

screw threading a non-wooden durable screw threaded generally cylindrical insert into said socket, said insert matching said socket,

forcing said liquid adhesive by screw threading said insert to cause penetration of adhesive behind the face through the volume of the wooden head from the socket to the exterior surface of the wooden head whereby said adhesive upon solidification provides a solid golf ball hitting head attributable to the coaction of the insert so bonded into the head and the wooden face is protected against deterioration upon impact with a golf ball.

8. The method of claim 7 wherein said glue is selected from the group consisting of resorcinolformaldehyde resin and epoxy resin.

9. The method of claim 7 wherein a plurality of counter-bored sockets are provided in the hitting face with said insert glued into each.

10. The method of claim 7 further comprising providing a central face plate in said face from the top to the bottom of said face and said socket is counter-bored into the head on either side of said plate.
