Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A composite ball bat which comprises: a solid wooden elongated barrel with a reduced diameter section; a handle longitudinally aligned and integral with said barrel; a metallic sleeve surrounding said reduced diameter barrel section to form a preferred ball hitting area, said sleeve being configured to smoothly continue the eternal contour of said barrel; and a retainer means, said retainer means being installed in the distal end of the barrel and being configured to engage said sleeve and hold the sleeve in place on the reduced diameter barrel section of the bat wherein said solid wooden elongated barrel and said metallic sleeve function to dampen vibrations in the composite ball bat when the composite ball bat is struck by a ball.
Claim 2
Dependent Claim
121 words

A composite ball bat as defined in claim 1 in which there is a first annular ledge at the proximate end of the reduced diameter barrel section and a second, complementary annular ledge on said retainer means, said metallic sleeve being trapped between said first and second ledges with opposite, first and second ends of said sleeve engaging said ledges.
Claim 4
Dependent Claim
33 words
A composite ball bat as defined in claim 2 in which the contours of said sleeve at the first and second ends thereof respectively match the contours of said first and second ledges.
Claim 5
Dependent Claim
77 words
A composite ball bat as defined in claim 1 in which: there is a recess in said barrel that opens onto the distal end of the barrel and is centered on the longitudinal centerline of the bat; and said retainer means has an integral plug which is seated in said recess with an annular step at a retainer means integrated end of said plug engaging the distal end of the reduced diameter barrel section of the bat.
