Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A ball bat comprising an elongated hollow metal body with a ball striking portion of predetermined outer diameter tapering through an intermediate portion of a predetermined outer diameter to a handle portion of reduced outer diameter, vibration dampening means disposed at least at one end of the hollow metal body, and a hand restraining knob means disposed at the handle end of the ball bat, the wall thickness of any cross section of said striking portion and said intermediate portion being similarly eccentric throughout their length, said eccentricity being of a predetermined contiguous arcuate wall sector of greater thickness than the remaining wall sector, and wherein said bat has a substantially uniform weight per unit length along a suBstantial portion of the bat length, and means provided on the exterior surface of the bat coinciding with the wall thickened arcuate sector of said striking portion to indicate to the user the proper orientation of the ball bat.
Claim 2
Dependent Claim
157 words
A ball bat comprising an elongated hollow metal body with a ball striking portion of predetermined outer diameter tapering through an intermediate portion of a predetermined outer diameter to a handle portion of reduced outer diameter, vibration dampening means disposed at least at one end of the hollow metal body, and a hand restraining knob means disposed at the handle end of the ball bat, the wall thickness of any cross section of said striking portion and said intermediate portion being similarly eccentric throughout their length, said eccentricity being of a predetermined contiguous arcuate wall sector of greater thickness than the remaining wall sector, and wherein said bat has a substantially uniform weight per unit length along a suBstantial portion of the bat length, and means provided on the exterior surface of the bat coinciding with the wall thickened arcuate sector of said striking portion to indicate to the user the proper orientation of the ball bat.
Claim 3
Dependent Claim
24 words
The ball bat as specified in claim 1, wherein the predetermined contiguous arcuate sector preferably extends through an angle of about 180* or more.
