Golf ball

A golf ball comprising:

• a) an inner core of a first material and including:
• i) a central portion having an outer surface;
• and
• ii) a plurality of projections extending radially outward from the central portion, said projections having a base-adjacent the outer surface, a free end, and each projection tapers from the base toward the free end, and each base being circular, and each base having a diameter greater than the height of the projection;
• b) a non-wound outer core formed of a second material and being disposed around the inner core so that the outer surface of the outer core is substantially spherical;
• and
• c) a cover surrounding the inner core and the outer core.

A golf ball comprising:

• a) an inner core formed of a first material and including a substantially spherical outer surface that includes a plurality of projections formed so that gaps are formed surrounding each projection, and each projection having a base adjacent the outer surface and a spaced free end, and each projection has a maximum length greater than a maximum width and a width of the free end is greater than a width of the base;
• b) an outer core formed of a second material and being disposed around the inner core;
• and
• c) a cover surrounding the outer core.

A golf ball comprising:

• a) an inner core of a first material and including:
• i) a central portion;
• and
• ii) a plurality of spaced projections extending radially outward from the central portion forming gaps between each projection, where the inner core includes an inner core volume that includes only the first material;
• b) an outer core formed of a second material, said second material being disposed within the gaps and the outer core includes an outer core volume that includes the first and second materials, the outer core having an outer surface and the projections extend substantially to the outer surface, the inner core and the outer core defining a transition volume, the transition volume being the difference between the outer core volume and the inner core volume, the transition volume being at least 10% of the outer core volume;
• and
• c) a cover surrounding the inner core and the outer core;
• wherein a first ratio of load over deflection for the first material differs from a second ratio of load over deflection for the second material by at least about 10%.

A golf ball comprising:

• a) an inner core formed of a first material and including a substantially spherical outer surface that includes a plurality of projections formed so that gaps are formed surrounding each projection, and the projections having a maximum length greater than the maximum width;
• b) an outer core formed of a second material and being disposed around the inner core;
• and
• c) a cover surrounding the outer core;
• wherein the surface of each projection is curved along the maximum width and the maximum length.

A golf ball comprising:

• a) an inner core formed of a first material and including a substantially spherical outer surface that includes a plurality of projections formed so that gaps are formed surrounding each projection, and the projections having a maximum length greater than the maximum width;
• b) an outer core formed of a second material and being disposed around the inner core;
• and
• c) a cover surrounding the outer core;
• wherein the surface of the inner core is described by the intersection of a first surface, a second surface, and a third surface, the first surface being formed by a wave form extending about a first axis, the second surface being formed by the wave form extending about a second axis, and the third surface being formed by the wave form extending about a third axis.

• b) an outer core formed of a second material and being disposed around the inner core;
• and
• c) a cover surrounding the outer core;
• wherein:
• the first material has a first Shore D hardness, a first elastic modulus, a first specific gravity, and a first Bayshore resilience;
• the second material has a second Shore D hardness, a second elastic modulus, a second specific gravity, and a second Bayshore resilience;
• and
• the first and second materials are selected so that at least one material property is in the group consisting of the first Shore D hardness differing from the second Shore D hardness by at least 10 points, the first elastic modulus differing from the second elastic modulus by at least 10%, the first specific gravity differing from the second specific gravity by at least 0.1, and the first Bayshore resilience that differing from the second Bayshore resilience by at least 10%.
