Uniformly weighted golf ball

Abstract

A golf ball in which the core is made from one material and the cover from a different material yet the density of the core and the density of the cover material are essentially identical.

What is claimed is:  
     
         1 . A golf ball comprising 
 a spherical core made from a first material,    at least one layer of a second different material completely covering said core wherein the density of said core and the density of said one layer surrounding said core are essentially identical and wherein any additional layer surrounding said core and said one layer has a density essentially identical to the density of said core, and wherein the constituents of said material in said layer are uniformly distributed therein.    
     
     
         2 . The golf ball of  claim 1  wherein said core has been prepared by centerless grinding.  
     
     
         3 . The golf ball of  claim 1  wherein said core is a blend of polybutadiene and a zinc monomer.  
     
     
         4 . The golf ball of  claim 1  wherein said core is completely covered by at least one layer of a suitable material which contains density altering constituents so that its density is essentially identical to the density of said core.  
     
     
         5 . The golf ball of  claim 1  wherein said core is covered by one or more layers of a material selected from the group consisting of urethane, balata, and an ionomer resin or any combination of these materials, which have been modified with density altering constituents such that the density of the core, said one or more layers, and the complete ball will be essentially the same.
