Patent ID: 7198581

Claim:
A system for improving hitting, comprising: a ball of the same size and shape as a baseball or softball; and, a baseball bat for hitting the ball comprising; a cylindrical tube whose length is similar to a conventional baseball bat and, whose outer diameter over an area used for hitting the ball is smaller then the diameter of a conventional baseball bat over an area used for hitting the ball, and whose outer surface is uniform, having a bore of consistent diameter which extends from an inner end to a distal end of said tubular cylindrical tube and said member cylindrical tube is made out of a material that will not be damaged when said cylindrical tube is used to strike the ball; a plurality of weight members which vary as to length, density, and weight that are adapted to fit slidebly within the bore and said weight members can be placed in the boar or removed from the boar and there are more weight members than necessary to fill the cylindrical so that said weight member can be placed within the boar in different combination and mixtures with the combinations to change the balance and weigh of the bat and make said weigh and balance similar to to a conventional bat; and a means to compress said weight members within said boar to ensure that the weights do not move; and, an inner cap attachable to said inner end of said tubular member for retaining said weight members within said bore.
