Compound safety ball
First Claim
1. A compound ball for simulating the performance of a regulation size ball for the playing of a sport, comprising an outer shell and an inner shell dimensioned to provide a spacing between the outer and inner shells, the outer shell being spherical and formed of molded polymeric material and defining circular apertures spaced over the surface of the outer shell, the inner shell being gas filled and comprised of a material capable of resiliently rebounding in response to being compressed by the outer shell upon deformation of the outer shell in response to being hit, the apertures in the outer shell permitting air to pass through the apertures when the compound ball is in flight, the inner shell providing mass and impact rebound within the outer shell for simulating the action of a regulation ball when thrown, caught, hit or impacts an object.

Abstract
A compound ball simulates the performance of a regulation size baseball, softball, and golf ball. It is formed of spherical outer and inner shells dimensioned to abut one another or to provide a spacing between them. The outer shell is formed of molded polymeric material with circular apertures spaced over its surface. The inner shell is gas filled and resiliently rebounds in response to being compressed by the outer shell upon deformation of the outer shell in response to being hit, as by a bat or club. The apertures in the outer shell permit air to pass trough the apertures when the compound ball is in flight. The inner shell provides mass and impact rebound within the outer shell for simulating the action of a regulation ball when thrown, caught, hit or impacts an object. The outer shell may also contain raised dimpling to impart greater aerodynamic drag on the compound ball, further limiting its flight and range, or altering its performance.
