Abstract: A golf ball characterized by enhanced flight distance and enhanced aerodynamic symmetry, the ball having a generally spherical surface with dimple patterns thereon, the improvement comprising between about 75% and 85% of the ball spherical surface occupied by the dimples; there being smaller and larger dimples, all of which have diameters within the range of about 0.110 to 0.150 inches. There are dimple-free multiple great circle arcs on the ball surface, which define n-sided spherical surface polygons associated with opposite polar zones, with n.sup.2 -2n of the smaller dimples within each polygon. The ball also has an equator, and great circle arcs also defining multiple spherical surface triangles with legs on the equator, there being n.sup.2 +2n of the smaller dimples within each triangle.

Abstract: A golf putter head has a central portion made of a relatively light weight material such as a light alloy of extruded aluminum or extruded plastic alloy. To further reduce the weight of the central portion, this portion may be extruded and the face plate formed from a light polymer or rubber material. The toe and heel portions of the head are separately formed of a relatively heavy material such as sintered tungsten or tungsten copper. The toe and heel portions are similar to each other and are attached to the central portion by means of pins which fit into opposing holes formed in the ends of the central portion and the toe and heel end portions as well as well as screws which fit through apertures in the end portions and engage threads formed in the central portion. Employing a central portion which is much lighter in weight than the end portions provides an anti-twisting motion of inertia to the club head.

Multiple great circle arcs on the ball surface define six-sided spherical surface hexagons on axially opposite polar zones. Smaller dimples within each such hexagons are grouped in clusters of four, symmetrically about an axis of the ball centrally intersecting the hexagons.

Abstract: A golf club head has a pair of parallel longitudinal chambers running thereacross behind the face plate. A set of weight members having various weights is provided. Such weight members are selectively installed in the chambers to vary the center of gravity of the club head both horizontally and vertically to modify the driving action of the club as may be desired.

Abstract: A golf ball characterized by enhanced flight distance and enhanced aerodynamic symmetry, the ball having a generally spherical surface with patterns of dimples thereon comprising a ball having a main axis and opposite surface polar regions associated with the axis; there being six geodesic lines defining a spherical hexagon bordering each polar region, the axis being at the center of the hexagons; there being at least three groups of dimples associated with each hexagon, all of the dimples of the groups being completely within the spherical hexagon; the dimples of each group having the same diameter, the dimples of one group having diameters d.sub.1, the dimples of the second group having diameters d.sub.2, and the dimples of the third group having diameters d.sub.3, and; the dimples of each group arranged symmetrically about the axis. The geodesic lines intersect to form six like isosceles spherical triangles respectively adjacent the six sides of each hexagon, and there re additional dimples confined by the triangles, with all dimples confined by each triangle being completely with each triangle. Each geodesic line has a length between its opposite ends which is at least 20% of its surface circumference of the golf ball. The golf ball has an equatorial region everywhere spaced from the spherical hexagons and the dimple density per unit area at the equatorial region is greater than the dimple density per unit area in the spherical hexagons.
