Total Claims: 22
Claim 1
Independent Claim
143 words

Claim 5
Dependent Claim
156 words
In a hollow metallic ball bat having a hollow generally cylindrical tapered bat barrel defined by a wall having a handle end and a ball striking end with a ball striking zone located adjacent the ball striking end and a hand grasp zone of smaller circumference than the ball striking zone located adjacent the handle end, the improvement comprising a concentrated weight load incorporated into the bat barrel immediately adjacent the ball striking end of the barrel and spaced axially outwardly of the ball striking zone to preclude the concentrated weight load from interfering with flexing of the wall of the bat barrel when the ball striking zone strikes a ball, said concentrated weight load including a hardenable material placed in the bat barrel when in a flowable state and a plurality of discrete particles of material having a greater specific weight than the hardenable material generally uniformly distributed throughout the volume of said hardenable material.
Claim 6
Dependent Claim
156 words
In a hollow metallic ball bat having a hollow generally cylindrical tapered bat barrel defined by a wall having a handle end and a ball striking end with a ball striking zone located adjacent the ball striking end and a hand grasp zone of smaller circumference than the ball striking zone located adjacent the handle end, the improvement comprising a concentrated weight load incorporated into the bat barrel immediately adjacent the ball striking end of the barrel and spaced axially outwardly of the ball striking zone to preclude the concentrated weight load from interfering with flexing of the wall of the bat barrel when the ball striking zone strikes a ball, said concentrated weight load including a hardenable material placed in the bat barrel when in a flowable state and a plurality of discrete particles of material having a greater specific weight than the hardenable material generally uniformly distributed throughout the volume of said hardenable material.
Claim 7
Dependent Claim
19 words
The bat of claim 2, wherein each of the particles is encapsulated within the volume of the hardenable material.
Claim 8
Dependent Claim
16 words
The bat of claim 5, wherein each of the particles is surrounded by said hardenable material.
Claim 9
Dependent Claim
26 words
The bat of claim 6, wherein there is an amount of the hardenable material between the interior surface of the bat barrel wall and the particles.
Claim 10
Dependent Claim
23 words
The bat of claim 4, wherein the number of particles may be varied without substantial variation in the volume of, the hardenable material.
Claim 11
Dependent Claim
25 words
The bat of claim 4, wherein the particles are dispersed throughout the volume of the hardened material in a pattern balanced about a longitudinal axis.
Claim 12
Dependent Claim
16 words
The bat of claim 9, wherein said particles are organized to occupy a geometrically shaped volume.
Claim 13
Dependent Claim
17 words
The bat of claim 10, wherein the geometrically shaped volume occupied by the particles is a cone.

Claim 15
Dependent Claim
24 words
The bat of claim 11, wherein the cone shaped volume is oriented with the apex pointed toward the handle end of the bat barrel.
Claim 16
Dependent Claim
18 words

Claim 17
Dependent Claim
40 words
The bat of claim 2, wherein said weight load is rigid with the bat and balanced about a longitudinal axis of the bat barrel to prevent inertial torque forces occurring when a ball is struck by the ball hitting zone.
Claim 18
Independent Claim
174 words
The method of forming a hollow metal bat consisting of the steps of forming a hollow one-piece bat barrel with a ball striking zone adjacent a closed outer end of the bat barrel and a hand gripping zone adjacent an inner end of the bat barrel and incorporating a concentrated weight load internally of the bat barrel with the inner end of the weight load being spaced outwardly from the ball hitting zone to prevent the weight load from interfering with flexing of the wall of the bat barrel in the ball hitting zone when the bat strikes a ball in the ball hitting zone to obtain maximum ball velocity and distance, said step of incorporating the concentrated weight load internally of the bat barrel including the steps of leaving the inner end of the bat barrel open, and inserting the concentrated weight load through the open inner end of the bat barrel, orienting the concentrated weight load in the outer end of the bat barrel in spaced relation to the ball striking zone.
Claim 19
Independent Claim
174 words
The method of forming a hollow metal bat consisting of the steps of forming a hollow one-piece bat barrel with a ball striking zone adjacent a closed outer end of the bat barrel and a hand gripping zone adjacent an inner end of the bat barrel and incorporating a concentrated weight load internally of the bat barrel with the inner end of the weight load being spaced outwardly from the ball hitting zone to prevent the weight load from interfering with flexing of the wall of the bat barrel in the ball hitting zone when the bat strikes a ball in the ball hitting zone to obtain maximum ball velocity and distance, said step of incorporating the concentrated weight load internally of the bat barrel including the steps of leaving the inner end of the bat barrel open, and inserting the concentrated weight load through the open inner end of the bat barrel, orienting the concentrated weight load in the outer end of the bat barrel in spaced relation to the ball striking zone.
Claim 20
