Structure of a baseball

Abstract

A base ball includes a central spherical core made of high density cork, a plurality of highly elastic rubber layers wound upon said core, a first layer of blended wool yarns with different diameters wound upon said rubber layers, a second layer of blended wool yarns with different diameters wound upon said first layer, a moisture proof layer of soft foam wound upon said second layer, a layer of yarns wound upon said moisture proof layer and then sprayed with adhesive agent, and an outer cover encasing said layer of yarns, whereby the moisture proof layer of soft foam can effectively prevent the base ball from getting moisture and can provide stable resiliency thereby enabling the base ball to keep its weight and resiliency at a stable condition and therefore warranting fair play even in bad weather.

I claim:  
     
         1 . A base ball comprising: 
 a central spherical core made of high density cork;    a plurality of highly elastic rubber layers wound upon said core;    a first layer of blended wool yarns with different diameters wound upon said rubber layers;    a second layer of blended wool yarns with different diameters wound upon said first layer;    a moisture proof layer of soft foam wound upon said second layer;    a layer of yarns wound upon said moisture proof layer and then sprayed with adhesive agent; and    an outer cover encasing said layer of yarns.
