Abstract
Abstract A hosel is formed with an upwardly opening socket for receiving a shaft that has a projecting flange with an outer edge. A ball striking plate is manufactured in separate form from the hosel and is secured to the flange in desired positions of loft and other relationships. One or more weights are arranged to be secured to the rear side of the ball striking plate for providing a desired club head weight and center of gravity. A method of the invention includes the steps of forming a hosel and the ball striking plate as separate elements and then shaping and positioning the flange for securing the ball striking plate at the desired angle and position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A golf club iron comprising a head portion, said head portion including a hosel having means arranged to connect it to a shaft, said head portion also including a body member formed independently of said hosel, said body member having top and bottom edges and first and second end edges, said body member also having a front ball striking face and a rear face, and weld means engageable between said hosel at said first end edge of said body member securing said body member to said hosel in a desired permanently positioned loft and lie, said top and bottom edges of said body member and said second end edge thereof comprising perimeter edges of said head portion.
Claim 2
Dependent Claim
117 words
A golf club iron comprising a head portion, said head portion including a hosel having means arranged to connect it to a shaft, said head portion also including a body member formed independently of said hosel, said body member having top and bottom edges and first and second end edges, said body member also having a front ball striking face and a rear face, and weld means engageable between said hosel at said first end edge of said body member securing said body member to said hosel in a desired permanently positioned loft and lie, said top and bottom edges of said body member and said second end edge thereof comprising perimeter edges of said head portion.
Claim 3
Dependent Claim
38 words
The golf club iron of claim 1 wherein said body member is formed from plate material whereby to have flat front and rear faces, and at least one independently formed, preselected weight secured permanently to said rear face.
Claim 4
Dependent Claim
91 words
The golf club iron of claim 1 wherein said body member is formed from plate material whereby to have flat front and rear faces, and independently formed, preselected weight means secured permanently to said rear face, said weight means including a main weight and a secondary weight, said secondary weight being of lesser selected value than said main weight and being used to provide a fine value of club head weight, said secondary weight comprising a shim-like insert disposed between said main weight and the rear face of said body member.
Claim 5
Independent Claim
127 words
The method of constructing a golf club iron having a head portion for striking a golf ball, said method comprising the steps of forming a hosel as a part of said head portion with means for receiving a shaft, forming a body member as a part of said head portion but formed independently of said hosel, said body member being formed with top and bottom edges and first and second end edges, said body member also being formed with a ball striking face and a rear face, and welding said body member at its said first end edge to said hosel in a desired permanently positioned loft and lie with said top and bottom edges and said second end edge comprising perimeter edges of said head portion.
Claim 6
Independent Claim
127 words
The method of constructing a golf club iron having a head portion for striking a golf ball, said method comprising the steps of forming a hosel as a part of said head portion with means for receiving a shaft, forming a body member as a part of said head portion but formed independently of said hosel, said body member being formed with top and bottom edges and first and second end edges, said body member also being formed with a ball striking face and a rear face, and welding said body member at its said first end edge to said hosel in a desired permanently positioned loft and lie with said top and bottom edges and said second end edge comprising perimeter edges of said head portion.
Claim 7
Dependent Claim
35 words
The method of claim 4 wherein said body member in its formation has flat front and rear faces, and including the step of securing independently formed, preselected weight means permanently to said flat rear face.
Claim 8
Dependent Claim
79 words
The method of claim 4 wherein said hosel is formed integrally with a laterally projecting flange having an outer free edge, and including the step of shaping said outer free edge of said flange and positioning said body member relative to said flange to provide securement of said first end edge of said body member to said outer free edge of said flange at a selected angle to accomplish a desired loft and lie of said ball striking head.
Claim 9
Dependent Claim
25 words
The method of claim 6 wherein said flange when formed with said hosel is of an enlarged size to accommodate shaping of various club heads.
Claim 10
Independent Claim
100 words
The method of constructing a golf club comprising the steps of forming a hosel with means for receiving a shaft, forming a ball striking head independently of said hosel, said ball striking head being formed with opposite end portions and said hosel being formed with a laterally projecting flange having an outer free edge, and shaping said outer free edge of said flange and positioning said striking head relative to said flange while securing said end edge to said free edge of said flange at a selected angle to accomplish a desired loft and lie of said ball striking head.
Claim 11
Independent Claim
100 words
The method of constructing a golf club comprising the steps of forming a hosel with means for receiving a shaft, forming a ball striking head independently of said hosel, said ball striking head being formed with opposite end portions and said hosel being formed with a laterally projecting flange having an outer free edge, and shaping said outer free edge of said flange and positioning said striking head relative to said flange while securing said end edge to said free edge of said flange at a selected angle to accomplish a desired loft and lie of said ball striking head.
Claim 12
Dependent Claim
25 words
The method of claim 8 wherein said flange when formed with said hosel is of an enlarged size to accommodate shaping of various club heads.
