US Patent:

42419190, Dec 30, 1980

Filed:

Dec 26, 1978

Appl. No.:

5/973039

Inventors:

Ronald Foreman - King of Prussia PA

International Classification:

A63B 5906

US Classification:

273 72A

Abstract:

An aluminum baseball bat with plug of solid rubber or similar material at one end thereof and a knob at the other end is disclosed. The rubber end plug is sealed in place in a leak-proof junction to define a hollow interior space. By inserting a needle through the end plug, fluid communication between a source of air or other gas which is pressurized either above or below atmospheric pressure and the interior of the bat space can be provided to achieve a desired pressure therewithin. Once the desired interior pressure has been achieved, the needle is withdrawn and the natural resiliency of the rubber acts to immediately seal the puncture to thereby permanently maintain the desired interior pressure conditions.

International Classification:

B23P 1102

US Classification:

29451

Abstract:

A method for manufacturing a baseball or softball bat formed of hollow metal tubing having a short weight plug of hard rubber anchored at the extreme end of the striking portion of the bat by a knob protruding from the weight plug through a hole in the end of the bat including inserting the weight plug in the tubing prior to forming the end of the bat, partially closing the end of the bat and forming a hole, positioning the plug by gas pressure developed within the hollow of the bat and forcing the knob through the end hole.
