Abstract: A finished, regulation long range, solid construction, multi-piece golf ball including a discrete cover and a core. The core has an inner and an outer portion. Either the outer portion or the entire core has a plurality of gas containing compressible cells dispersed therein, and either the outer portion or the entire core the a specific gravity greater than 1.The compressible cells are produce by a method selected from the group consisting of foaming, using a blowing agent, injecting a gas and incorporating a plurality of microspheres having a flexible outer surface.

Abstract: The invention relates to a golf ball having a substantially spherical inner core, a layer of high tensile elastic modulus fibers wound about the inner core, and a molded layer of a polymeric material surrounding the wound layer. The high tensile elastic modulus fibers have a tensile elastic modulus of at least 10,000 kpsi. The invention also relates to a method of making a golf ball and includes providing an inner core, winding a high tensile elastic modulus fiber on the inner core to create a wound layer, and molding an outer layer of polymeric material about the wound layer. The inner core may be made of resilient materials or a center wound with a low modulus fiber and provided with an initial tension.

Abstract: The subject invention relates to a golf ball having the beneficial characteristics of both a wound and solid construction ball. The invention is directed to a non-wound golf ball incorporating a compressible material, such as a gas, as part of its core. The compressible material can be dispersed throughout the entire core or only in a part of the core. The compressible material or gas can be incorporated into the core by including or dispersing microspheres having a flexible shell containing the compressible material or gas. The golf balls of this invention combine the feel and playing characteristics of a wound construction ball with the shelf-life, manufacturing simplicity and durability of solid construction golf balls.

Abstract: An apparatus for practicing a method of determining the effective putter loft of a golf putter as swung by a particular golfer in which the putter has a curved face unit placed on the hitting surface and the putter is then swung by such particular golfer against a hitting cylinder. The location of impact between the curved face and hitting cylinder provides data from which the effective loft can be determined.

Abstract: A golf ball having a spherical surface with a plurality of dimples formed therein, the spherical surface comprising eight spherical triangles delineated by three great circle parting lines not intersecting any dimples, said parting lines being formed by projecting the edges of an inscribed regular octahedron onto said spherical surface, each of said triangles having dimples located within such parting lines such thata) the division of each triangle by three division lines angularly spaced at 120 degrees from one another and originating at the center of each triangle forms three spherical guadrilaterals each having identical dimple patterns; andb) each of said patterns is not bilaterally symmetrical across any apex line extending from the center of the triangle to an apex of the triangle.

Abstract: A golf ball having three or more sets of dimples with each set having substantially the same dimple diameter and each dimple of each set having the same dimple edge angle. Each set of dimples has diameters which differ substantially from each other set. Golf balls having 50% to 80% or more of their surfaces covered with dimples are within the present invention.

Abstract: The golf ball has no three dimples in a row with edges aligned. This pattern produces a golf ball with reduced drag. The preferred golf ball has multiple sizes of dimples.

Abstract: A golf ball having dimples covering its surface and having four great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The four great circular paths are obtained by laying out an octahedron on the surface of the golf ball and connecting the midpoint of each edge of the octahedron to form eight equilateral triangles and four squares. The dimples are arranged by filling each triangle and square with dimples. Golf balls having four great circular paths and 456, 408 and 432 dimples are disclosed.

Abstract: A golf ball having an outer spherical surface and at least 320 dimples formed in the outer surface to provide land areas on the outer surface which surround the dimples. Each of the dimples has a triangular periphery at the ball's outer surface provided by three sides and three flat surfaces which extend inwardly from the outer surface. The angle between each of the flat surfaces and a tangent to the ball's outer surface at the intersection with the flat surface is from 14.degree. to 26.degree.. Each side of each dimple extends parallel to at least a portion of the side of an adjacent dimple. The distance between the parallel sides of adjacent dimples is constant over the outer spherical surface. The total land area is no greater than 20% of a sphere which circumscribes the ball's outer spherical surface.

Abstract: A golf ball is provided with evenly and uniformly distributed dimples so that six great circle paths on the surface of the golf ball do not intersect any dimples. The spherical surface of the golf ball is divided into 20 identical spherical triangles corresponding to the faces of a regular icosahedron. Each of the 20 triangles is further subdivided into four smaller triangles consisting of a central triangle and three apical triangles by connecting the midpoints of each of the 20 triangles along great circle paths. The dimples are arranged so that the dimples do not intersect the sides of any of the central triangles.
