Golf ball

A spherical ball and a method of making the spherical ball wherein the ball has a plurality of elongated dimples substantially covering the outer surface of the ball without any dimple overlap. The elongated dimples are of at least two types including a first plurality of dimples having a minor axis and a major axis which together form the long axis of the first plurality of dimples the minor axis being less than the major axis. A second plurality of dimples has a minor axis equal to that of the first plurality of dimples and a major axis less than the major axis of the first plurality of dimples but greater than the minor axis.

Golf ball and method of forming dimples thereon

A golf ball including two poles and an equator is characterized by the arrangement of a preselected number of dimples in a geometrical lattice configuration based upon a subdivided tetrahedron on the surface thereof The lattice includes six dimple-free great circles around the circumference of the ball, one of the circles corresponding with the equator and another of the circles passing through the poles. All of the circles define twenty-four generally equivalent triangles, twelve in each hemisphere of the ball. An equal number of dimples are arranged within each of the triangles, and the dimple arrangement in at least two of the triangles is different from the dimple arrangement in the remaining triangles.

Tetrahedral dimple pattern golf ball

A golf ball having a dimple-free equatorial line dividing the golf ball into two hemispheres;

A two-piece golf ball of improved playing characteristics comprising

A golf ball having an octahedral pattern about its surface with four identical quadrants in each hemisphere. Each quadrant includes a circular area which fills the quadrant as completely as possible without crossing the quadrant boundaries. A dimple is located at each pole. Each circular area is substantially filled with dimples and the remaining interstitial areas between the circular areas and the poles are substantially filled with dimples while leaving a dimple free equatorial line.

Golf ball and dimple pattern forming process

A dimple configuration for the surface of a golf ball is provided by selecting a fixed number of dimples, placing said dimples on a model of the ball in random, helter-skelter locations on one selected section without regard to the other dimples present, and identifying each dimple and the adjacent dimples which overlap it. For each dimple so identified, the aggregate component of overlap in the longitudinal and latitudinal directions is determined, the center of each dimple is relocated so as to minimize overlap, and the steps of identifying, determining, and relocating are repeated for each dimple until the aggregate overlap is reduced to a predetermined amount. The resultant ball provides a random dimple configuration which has no repeating patterns within the sections.
