Golf ball
First Claim
1. A golf ball having a spherical surface with a plurality of dimples formed thereon, and seven parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four isosceles triangles and eight equilateral triangles, said twenty-four isosceles triangles and eight equilateral triangles being formed by inscribing a cuboctahedron in said spherical surface and bisecting each square face on said cuboctahedron into four isosceles triangles, four of said seven parting lines corresponding to the edges of said cuboctahedron and the remaining three of said seven parting lines corresponding to the square faces'"'"' bisecting lines, said dimples being arranged in said twenty four isosceles triangles and said eight equilateral triangles such that the dimples do not intersect the seven parting lines.

Abstract
A golf ball having dimples covering its surface and having seven great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The seven great circular paths are obtained by laying out a cuboctahedron on the surface of the golf ball, dividing each of the six square faces of the cuboctahedron into four isosceles triangles by bisecting each square twice. The dimples are arranged by filling each triangle with dimples. A cuboctahedron is a fourteen-sided figure with eight triangular faces and six square faces. Bisecting the square faces twice provides a total of 32 triangles per cuboctahedron. Golf balls having seven great circular paths and 360, 384 and 408 dimples are disclosed.

- 8. A golf ball having a spherical surface with a plurality of dimples thereon and seven great circular paths which do not intersect any dimples, the circular paths being arranged on the spherical surface by inscribing a cuboctahedron in the spherical surface and bisecting each square face of said cuboctahedron twice to form four isosceles triangles, said seven great circular paths corresponding to the bisecting lines of said square faces, which define three great circular paths, the remaining four great circular paths corresponding to the edges of the cuboctahedron.

15. A golf ball having a spherical surface with a plurality of dimples thereon and seven parting lines which do not intersect any dimples, four of said seven parting lines corresponding to circular paths which coextend with edges of a cuboctahedron inscribed in said spherical surface, and the remaining three parting lines of said seven parting lines coextend with twelve bisecting lines, said twelve bisecting lines corresponding to lines that bisect square faces of said cuboctahedron to form four isosceles triangles, said dimples being arranged in said isosceles triangles and in equilateral triangles of said cuboctahedron.
