ABSTRACT:
A game ball for use as a conventionally sized baseball or softball comprises an inner core of a first material characterized by at least high durability; at least one locator pin of the first material extending radially outwardly from and affixed to the inner core; and a spherical outer core of a second material, characterized by at least high durability and conventional rebound. Preferably, the inner core has four integrally formed locator pins extending radially outwardly therefrom. These pins are positioned 90.degree. apart on an imaginary plane through the equator of the inner core. The first material is selected from the group consisting of cork, kapok, rubber, or a thermoplastic resin such as an ethylene vinyl acetate copolymer, an ethylene acrylic acid copolymer or a blend of both. The second material for the outer core, preferably polyurethane foam, consists of 100 parts of a resin mixture, a blowing agent, and either 51 or 60 parts isocyanate. The resin mixture comprises between about 95 or 97 percent polyether polyol and small amounts of silicone and a catalyst.
