Abstract

A golf ball has dimples formed on its surface which are in a pattern covering the entire surface and which has square dimples and round dimples which are interspersed with each other in a generally uniform manner. This end result is achieved by arranging most of the dimples in circles which run around the ball and with alternate round and square dimples. A first group of the circles run parallel to each other and a second group of the circles run parallel to each other with the circles of the first group being substantially perpendicular to those of the second group. So as to completely cover the surface of the ball with dimples, the uniform alternate round and square dimple pattern is necessarily interrupted at several places. About 432 dimples are placed on the surface of the ball for optimum aerodynamic effect.

Claims

1. A golf ball having dimples formed on the surface thereof, said dimples being arranged in a pattern comprising:

a first group of substantially parallel circles of alternate round and square dimples, and

a second group of substantially parallel circles of alternate round and square dimples,

the circles of said second group being substantially perpendicular to the circles of said first group, said round and square dimples causing substantially the entire surface of said golf ball.

2. The gold ball of claim 1 wherein said golf ball has approximately 432 dimples.

3. The golf ball of claim 1 wherein the surface of the ball is divided into eight similar spherical triangles the sides which are formed by portions of said circles, there being additional cluster of round and square dimples located substantially in the centers of said triangles.
