Abstract

An improved golf club head constructed having a hitting face or cushioned insert, crown and a sole. An interlocking bridge is formed between the crown and hitting face to reduce vibrations upon impact with a golf ball. Various metals are used in the construction and are joined together at the sole for perimeter weighting or balancing of the golf club head.

Claims

1. A golf club head comprising:

the club head having a hosel, a shell with a recess, a striking face-plate, a sole and a single looped ring for encasing attachment with the striking face-plate, said striking face-plate encasement being mechanically wedded to the shell via the recess and made up of a bridge having at least one metal element interlocked and sealed within the face of the shell thereby producing a cushioned effect for attenuating vibrations upon impact with a golf ball;

the shell being mechanically wedded to the sole, said sole further comprising a plurality of material disposed within the sole of the shell for materially balancing the club head shell.

2. The golf club head according to claim 1, wherein said club head is a metalwood.

3. The golf club head according to claim 1, wherein said club head is an iron.

4. The golf club head according to claim 1, wherein the shell comprises at least one of stainless steel, aluminum or titanium.

5. The golf club head according to claim 1, wherein the looped ring is a soft metal made of at least one of copper, brass or aluminum.

6. The golf club head according to claim 1, wherein the striking face-plate is a hard metal made of at least one of maraging steel, stainless steel or titanium.

7. A method of making an improved golf club head comprising the method steps of:

(a) shaping the shell having a recess and at least one opening for attaching of at least one metal plate thereto,

(b) making a sole plate for wedded attachment to the shell,

(c) making a metal face-plate for wedded attachment to the shell,

(d) the step of making a metal face-plate as in step (c) further including the step of encasing said face-plate with a metal looped ring for wedded attachment to the recess of the shell,

(e) the step of making a metal face-plate as in step (c) further comprising the step of forming a bridge made of a plurality of interlocking metal materials,

(f) insertably attaching and welding the plates of steps (b) and (d) to the shell,

(g) machining the plates of step (f), including the step of coating said plates to reduce wear from rust and corrosion.

8. The method of making an improved golf club head according to claim 7, wherein the bridge of step (e) is formed by brazing.

9. The method of making an improved golf club head according to claim 7, wherein the method step (b) further includes the step of sizing the sole plate for wedded attachment to the shell.

10. The method of making an improved golf club head according to claim 7, wherein the method step (b) further includes the step of sizing the face-plate for wedded attachment to the shell.
