Abstract
Abstract Apparatus for precision machining spherical faces of various radii and angles of loft or inclination on the hitting face of so-called wood golf clubs. The club head is adjustably mounted as to loft on a radius arm of adjustable radius with the club face centered relative to the axis of a rotatable milling cutter having at least one radially offset bit, and the arm is swung on the selected radius to cause the club face to traverse the cutter and generate a spherical milled surface on the face.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
Apparatus for forming a spherical surface on the hitting face of a wood golf club comprising, a fixed support plate, a radius arm having a pivot on said plate for arcuately swinging its free end about said pivot in the plane of said plate, means fixedly mounted on the free end of said arm for holding a wood golf club head having a hitting face thereon in upright position, means for swinging the radius arm on its pivot, and rotatable cutter means axially perpendicular to the hitting face of said head when the radius arm and cutter means are aligned, said cutter means bodily axially movable into contact with the hitting face and having at least one radially offset outwardly projecting bit adapted for defining a circular cutting line resulting in a generated spherical surface on the club hitting face as the radius arm swings the head across the cutter.
Claim 2
Dependent Claim
150 words
Apparatus for forming a spherical surface on the hitting face of a wood golf club comprising, a fixed support plate, a radius arm having a pivot on said plate for arcuately swinging its free end about said pivot in the plane of said plate, means fixedly mounted on the free end of said arm for holding a wood golf club head having a hitting face thereon in upright position, means for swinging the radius arm on its pivot, and rotatable cutter means axially perpendicular to the hitting face of said head when the radius arm and cutter means are aligned, said cutter means bodily axially movable into contact with the hitting face and having at least one radially offset outwardly projecting bit adapted for defining a circular cutting line resulting in a generated spherical surface on the club hitting face as the radius arm swings the head across the cutter.
Claim 3
Dependent Claim
28 words
Apparatus as defined in claim 1, having means for adjusting the swinging radius of said radius arm by adjusting the location of its pivot on the support plate.
Claim 4
Dependent Claim
31 words
Apparatus as defined in claim 1, having means for adjusting the holding means to change the loft angle of the club head face relative to the plane of said support plate.
Claim 5
Dependent Claim
31 words
Apparatus as defined in claim 2, haviNg means for adjusting the holding means to change the loft angle of the club head face relative to the plane of said support plate.
Claim 6
Dependent Claim
44 words
Apparatus as defined in claim 1, having means for rotatably adjusting the holding means in the plane of said radius arm to vary the angle between the cutter means and the hitting face resulting in a closed or open face on the club head.
Claim 7
Dependent Claim
44 words
Apparatus as defined in claim 2, having means for rotatably adjusting the holding means in the plane of said radius arm to vary the angle between the cutter means and the hitting face resulting in a closed or open face on the club head.
Claim 8
Dependent Claim
44 words
Apparatus as defined in claim 3, having means for rotatably adjusting the holding means in the plane of said radius arm to vary the angle between the cutter means and the hitting face resulting in a closed or open face on the club head.
Claim 9
Dependent Claim
44 words
Apparatus as defined in claim 4, having means for rotatably adjusting the holding means in the plane of said radius arm to vary the angle between the cutter means and the hitting face resulting in a closed or open face on the club head.
