Abstract: A golf ball construction wherein the dimples are distributed over the surfaces of the ball to minimize the appearance and effect of an unbroken seam line and to enhance the aerodynamic properties of the ball. The arrangement of the dimples includes a pole dimple at each pole, a pentagon formation of dimples in each hemisphere of the ball comprising five equally-spaced lines of dimples radiating outwardly from the pole dimple to thereby define five triangular areas of dimples in the pentagon formation, the bases of the triangular areas comprising five interconnected lines of dimples equally spaced from the pole dimple. Five equally spaced additional triangular areas are formed in each hemisphere, each having a base on the equator of the ball, and a plurality of additional dimples are then disposed in a non-uniform fashion about the remaining surface of the ball. The arrangement of the non-uniformly placed dimples favors the placement of the dimples closer to the equator of the ball.

Abstract: A golf ball construction wherein the dimples are evenly distributed over the surface to minimize the appearance and effect of an unbroken seam line. The dimples are arranged in three different patterns comprising a pentagon formation at each of the poles, five equally-spaced trapezoid formations in each hemisphere located between the pentagon pattern and the equator, and five equally-spaced triangular formations interposed between the trapezoid formations. The diameter of the dimples is also controlled to maintain the uniformity of the spacing.
