Baseball bat

A substantially hollow metallic ballbat having a high impact resistance and being adapted to a change in weight, center of gravity and repelling force which comprises a generally cylindrical barrel portion defining a generally cylindrical barrel chamber and a generally cylindrical handle portion defining a generally cylindrical handle chamber, said barrel portion and its associated chamber being larger in diameter than said handle portion and its associated chamber, respectively, said barrel portion being connected to said handle portion by a tapered intermediate portion which contains a tapered intermediate chamber which connects said barrel chamber with said handle chamber, and said barrel portion having an open end, a closure means removably disposed in the open end of said barrel portion and a hard, rigid, lightweight, high impact resistant, coiled, cylindrical reinforcing member removably disposed inside said barrel chamber and extending substantially the entire length of said barrel chamber and into the upper region of said tapered chamber, the outer periphery of said reinforcing member being in tight engaging relationship with the wall of the barrel chamber and the wall of the upper region of said tapered chamber and tending to expand against the increasing pressure of the walls of said barrel chamber and tapered chamber due to the changing diameter of said chambers, said reinforcing member producing a high impact resisting force in said bat.
