Summary for Patent: 8,409,038

Title:	Baseball bat
Abstract:	A novel baseball or softball bat is disclosed. The bat has a handle of a heavy, strong wood such as hickory, to resist breakage, and a barrel of a lighter wood such as sapele, to facilitate a controlled and comfortable swing. Methods for making the bat are also disclosed. It may be formed of a plurality of wedge-shaped pieces of wood, and the two species of wood may be joined by interleaving these wedges over part of the bat\'s length. The interleaving may optionally include a tongue and groove joint or a lap joint for increased strength, and some battens may optionally extend the entire length of the bat.

Patent Claims:	1. A bat comprising an elongate composite wooden structure, said structure comprising: (a) a first wooden batten formed from a first wood species having a first end, said first end comprising a tongue; and (b) a second wooden batten formed of a second wood species having a second end, said second end defining a groove so configured as to mate with said tongue; (c) wherein said first and second ends are closely adjacent and said tongue closely adjacent said groove; and (d) wherein said elongate composite wooden structure has a longitudinal direction and is tapered transverse to said longitudinal direction to form an elongate wedge. 2. The bat of claim 1 wherein a handle of the bat is formed of the first wood species and a barrel of the bat includes the second wood species. 3. The bat of claim 2 wherein the first wood species has a density of about 0.45-0.55 ounces per cubic inch and the second wood species has a density of about 0.35-0.37 ounces per cubic inch. 4. The structure of claim 1 wherein said first and second ends are cut at supplementary angles to one another. 5. The structure of claim 4 wherein said first and said second ends are not perpendicular to said longitudinal direction. 6. The structure of claim 1 wherein said tongue defines a plane, and said structure is symmetric about said plane. 7. The structure of claim 1 wherein said second end defines a recess into which said tongue is received. 8. A bat comprising an elongate wooden structure having a substantially uniform cross-section over its entire length, said structure comprising: (a) a first wooden batten having a first end; (b) a second wooden batten having a second end; and (c) a mating section wherein said first end and said second end overlap in a longitudinal direction; (d) wherein said substantially uniform cross-section is triangular. 9. The structure of claim 8 wherein said mating section is a lap joint. 10. The structure of claim 8 wherein said mating section is a tongue and groove joint. 11. A wooden bat having a longitudinal axis and a length, said bat comprising: (a) a first set comprising a plurality of elongate battens running longitudinally and disposed substantially cylindrically symmetrically about said axis; and (b) a second set comprising a plurality of elongate battens running longitudinally and disposed substantially cylindrically symmetrically about said axis, at least one batten in said second set being combined into a pair with at least one batten in said first set such that the pair extends over the entire length of the bat; (c) wherein said pair of battens meets at a tongue and groove joint. 12. The bat of claim 11 wherein said first set is composed of a first wood species and said second set is composed of a different wood species. 13. The bat of claim 11 wherein at least one of said first set of battens extends the entire length of the bat. 14. The bat of claim 11 wherein said first and second sets have the same number of battens and each batten in said first set forms a pair with one batten in said second set. 15. A wooden bat, comprising: a. a first section including a handle; and b. a second section including a barrel; wherein, c. said first and second sections each contain respective cylindrical portions and respective joint portions; d. said cylindrical portions are substantially cylindrically symmetrical about a longitudinal axis of said bat and so constructed as to be substantially free of air gaps; e. said respective joint portions each comprise wedges of wood arranged about said axis, each of said wedges having two longitudinally extending sides converging radially onto said axis, at least two of said wedges being separated from one another by a wedge-shaped space; and f. said respective joint portions being so constructed as to join matingly with each other, with the wedges from said handle section filling the spaces between the wedges of said barrel section, and vice versa, so that the sections, when joined, create a substantially solid bat.
