Abstract: A golf ball construction comprising a core and cover, the ball defining an equator forming a first great circle extending over the cover surface. At least two additional great circles extend over the cover surface and intersect the first great circle, the additional great circles being spaced apart equally with respect to each other whereby the ball surface is divided by the combination of the first great circle and the additional great circles into a plurality of discrete symmetrically arranged surface areas. A separate array of spaced-apart dimples is formed on the cover surface within each of the discrete surface areas, each of the arrays covering substantially completely the cover surface in each discrete surface area. Channels are formed exclusively within each area and extend between adjacent ones of the dimples in each area, a channel extending from each dimple to every other dimple adjacent thereto. None of the channels cross any of the great circles.

Abstract: A golf ball defining a spherical outer surface and a plurality of spaced-apart dimples formed in the surface. The dimples comprise a central raised portion and a surrounding depressed portion with the depressed portion having a lateral dimension along any straight line extending through the center of the central portion and from one outer edge to the opposite outer edge of the depressed portion. The maximum depth of the depressed portion is from 0.008 to 0.015 inches and the raised portion extends outwardly from the depressed portion to the position of the spherical outer surface. The maximum lateral dimension of the raised portion, measured parallel to the spherical outer surface, is less than one-half the minimum lateral dimension of the depressed portion. The total effective volume of the dimples comprising the cumulative volume occupied by the depressed portions of all dimples formed in said surface is greater than 0.021 cubic inches.

Abstract: A golf ball construction comprising a core, a cover, and an array of dimples formed on the exterior surface of the cover. The ball is characterized by a core diameter between 1.49 and 1.51 inches and by a cover thickness between 0.09 and 0.1 inches. Dimensions within these ranges are selected so that the overall ball diameter is between 1,685 and 1.695 inches, preferably 1.690 inches.
