Abstract
Abstract Wooden head for a golf club comprising a wooden body having a top surface, an undersurface carrying a soleplate, a rear surface and a face surface carrying a faceplate adapted to strike a golf ball during use of the golf club. The weight and balance of the head is adjustable by varying the weight of material present in spaced chambers within the wooden body. The chambers extend parallel to each other and to the swing axis of the head and are positioned towards the undersurface and rear surface of the wooden body, the rear surface being provided with openings through which covers can be removed from said chambers for purposes of varying the weight of material therein.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
278 words
Wooden head for a golf club comprising a wooden body having a core comprising its center of gravity, heel and toe sections on opposite sides of said core and separated by a central vertical axis plane which intersects said core, face and rear sections on opposite sides of said core and separated by a transverse vertical axis plane which intersects said core at an angle perpendicular to said central axis, sole and upper sections below and above said core and separated by a horizontal axis plane which intersects said core, and at least two hollow tubular openings in said wooden body extending from the surface of said face section to the surface of said rear section, each of said hollow tubular openings having cemented therein adjacent the surface of the rear section a self-contained capsule comprising a hollow tubular walled element adapted to contain variable amounts of weight material for purposes of adjusting the balance of the club head, the remaining portions of said tubular openings being filled with plastic material, the interior wall of each capsule being threaded for engagement with a threaded cover forming the closure means therefor, an equal number of said tubular openings being located within said wooden body on opposite sides of said central vertical axis plane in said heel and toe sections, behind said core and behind said transverse vertical axis plane in said rear section and beneath said core and horizontal axis plane, said tubular openings extending parallel to each other and to the central vertical and horizontal axis planes and having the closure means of the capsules exposed and removable through openings in the rear surface of the wooden body.
Claim 2
Dependent Claim
278 words
Wooden head for a golf club comprising a wooden body having a core comprising its center of gravity, heel and toe sections on opposite sides of said core and separated by a central vertical axis plane which intersects said core, face and rear sections on opposite sides of said core and separated by a transverse vertical axis plane which intersects said core at an angle perpendicular to said central axis, sole and upper sections below and above said core and separated by a horizontal axis plane which intersects said core, and at least two hollow tubular openings in said wooden body extending from the surface of said face section to the surface of said rear section, each of said hollow tubular openings having cemented therein adjacent the surface of the rear section a self-contained capsule comprising a hollow tubular walled element adapted to contain variable amounts of weight material for purposes of adjusting the balance of the club head, the remaining portions of said tubular openings being filled with plastic material, the interior wall of each capsule being threaded for engagement with a threaded cover forming the closure means therefor, an equal number of said tubular openings being located within said wooden body on opposite sides of said central vertical axis plane in said heel and toe sections, behind said core and behind said transverse vertical axis plane in said rear section and beneath said core and horizontal axis plane, said tubular openings extending parallel to each other and to the central vertical and horizontal axis planes and having the closure means of the capsules exposed and removable through openings in the rear surface of the wooden body.
Claim 3
Dependent Claim
33 words
Wooden head for a golf club according to claim 1 in which the surface of the face section comprises a plastic face plate which is integral with the plastic material within said openings.
Claim 4
Dependent Claim
239 words
Process for producing a wooden head for a golf club comprising a wooden body having a core comprising its center of gravity, heel and toe sections on opposite sides of said core and separated by a central vertical axis plane which intersects said core, face and rear sections on opposite sides of said core And separated by a transverse vertical axis plane which intersects said core at an angle perpendicular to said central axis, sole and upper sections below and above said core and separated by a horizontal axis plane which intersects said core, comprising the steps of boring an equal number of hollow tubular openings through said wooden body extending from said face section to said rear section in each of the heel and toe sections of said wooden body, on opposite sides of said vertical axis plane, beneath said core and horizontal axis plane and parallel to each other and to the central vertical and horizontal axis planes of said wooden body, inserting self-contained tubular walled elements into said tubular openings comprising capsules and securing said capsules at the rear sections of said openings behind said core and behind said vertical axis plane, said capsules being adapted to receive variable amounts of weight material and provided with closure means which are exposed and removable through openings in the rear surface of the wooden body, and filling the remaining portions of said tubular openings with a plastic material.
Claim 5
Dependent Claim
239 words
Process for producing a wooden head for a golf club comprising a wooden body having a core comprising its center of gravity, heel and toe sections on opposite sides of said core and separated by a central vertical axis plane which intersects said core, face and rear sections on opposite sides of said core And separated by a transverse vertical axis plane which intersects said core at an angle perpendicular to said central axis, sole and upper sections below and above said core and separated by a horizontal axis plane which intersects said core, comprising the steps of boring an equal number of hollow tubular openings through said wooden body extending from said face section to said rear section in each of the heel and toe sections of said wooden body, on opposite sides of said vertical axis plane, beneath said core and horizontal axis plane and parallel to each other and to the central vertical and horizontal axis planes of said wooden body, inserting self-contained tubular walled elements into said tubular openings comprising capsules and securing said capsules at the rear sections of said openings behind said core and behind said vertical axis plane, said capsules being adapted to receive variable amounts of weight material and provided with closure means which are exposed and removable through openings in the rear surface of the wooden body, and filling the remaining portions of said tubular openings with a plastic material.
Claim 6
Dependent Claim
37 words
Process according to claim 3 which comprises inserting a closure means into each of said capsules, selected from a group of closure means each having a distinct known weight, to adjust the balance of the wooden head.
Claim 7
Dependent Claim
46 words
Process according to claim 3 in which a portion of said face section of the wooden body is cut away and is filled with the plastic material used to fill said tubular openings to form a plastic faceplate integral with the plastic in the tubular openings.
Claim 8
Dependent Claim
22 words
Process according to claim 3 which comprises inserting different weight materials into said capsules to adjust the balance of the wooden head.
