Abstract
Abstract The multiple dimpled golf ball has 78% or more of its surface covered with dimples. For a golf ball with a total of 324 (332) dimples, 124 (132) dimples have a diameter of 0.157 inches and 200 dimples have a diameter of 0.17 inches. For a golf ball with a total of 384 (392) dimples, there are two configurations: (a) 144 (152) dimples have a diameter of 0.14 inches and 240 dimples have a diameter of 0.16 inches; or (b) 66 (72) dimples have a diameter of 0.13 inches and 318 (320) dimples have a diameter of 0.16 inches. For a golf ball with a total of 414 (422) dimples, 144 (152) dimples have a diameter of 0.14 inches and 270 dimples have a diameter of 0.15 inches. For a golf ball with a total of 484 (492) dimples, there are two configurations: (a) 174 (182) dimples have a diameter of 0.13 inches and 310 dimples have a diameter of 0.14 inches; or (b) 170 (178) dimples have a diameter of 0.13 inches, 260 dimples have a diameter of 0.14 inches, and 50 dimples have a diameter of 0.15 inches. For a golf ball having 320 triangular dimples, equilateral, isosceles and triangles with unequal sides are employed.
