Golf ball with symmetrical dimple pattern
First Claim
1. A golf ball comprising two hemispheres, an equator between said two hemispheres, and a plurality of dimples substantially covering the surface of said two hemispheres, said dimples being arranged to fall within a plurality of geometric shapes defined by drawing lines through the centers of peripheral dimples, said plurality of geometric shapes comprising a first plurality of regular polygons and a second plurality of irregular polygons, all of said first plurality of polygons being of the same size and shape, and all of said second plurality of polygons being of the same size and shape, said first and second plurality of polygons being so distributed that said golf ball is symmetric with respect too the center of said ball, said first plurality of polygons consisting of a plurality of regular heptagons, one heptagon of said plurality of heptagons being located at each of the poles of said ball and centered thereon, said second plurality of polygons consisting of a plurality of irregular pentagons, each pentagon of said plurality of pentagons having two short sides of a first length and three longer sides of a second length, said two short sides being separated by one of said longer sides, said plurality of pentagons including a plurality of equatorial pentagons, said equatorial pentagons comprising a first group of equatorial pentagons having bases in the northern hemisphere and parallel to the equator, and a second group of equatorial pentagons having bases in the sourthern hemisphere and parallel to the equator, said equatorial pentagons being so located that said equator bisects the short sides of all of said equatorial pentagons and intersects no dimples.

Abstract
A golf ball has dimples arranged as constrained by a plurality of geometric shapes, and the geometric shapes are located so the sphere of the ball is symmetric about the origin. There is a regular heptagon at each of the poles of the sphere, and bases of irregular pentagons are contiguous with the polar heptagon and surround the ball. Heptagons are then contiguous with the pentagons, followed by more pentagons which extend around the equator. The pentagons at the equator are alternately inverted with respect to one another, and the two hemispheres are alike. A line bisecting the short sides of the pentagons is a geodesic, and one of these is the equator. The equator is the only great circle not intersected by a plurality of dimples.
