Abstract
A baseball bat fabricated from a limb of a tree, procured without harvesting any of the tree's trunk. Because of this technique, the process of the present invention is much less wasteful. Many bats can be fabricated from a single tree, without felling the tree itself. The process of fabrication of the present invention is drawn to working with the properties of the harvested tree limb. In this manner, a billet is fabricated on a lathe with its center placed concentric with the center of the tree limb, thusly concentric with the limb's growth rings. By doing so, the growth rings within the limb will not be bisected during fabrication of the billet. When the billet is further turned on a lathe to shape the billet into a baseball bat, the growth rings within the limb will be minimally bisected, thus increasing the strength of the baseball bat of the present invention, as compared to the baseball bats of the prior art.

DETAILED DESCRIPTION OF THE DRAWINGS
[0021] FIG. 1 shows is a cross section of a baseball bat formed by the method of the present invention. The baseball bat of FIG. 1 comprises a handle (2) and a barrel (3). The handle (2) is from at the proximal end (4) of the baseball bat (1). The barrel is formed at a distal end (5) of the baseball bat (1). The center (10) of the baseball bat (1) runs the length of the baseball bat (1) from the proximal end (4) to the distal end (5).
[0022] FIG. 2 shows a perspective view of a baseball bat (1) formed by the method of the present invention. FIG. 4 is a view of just the knob of the baseball bat (1). As can be seen in FIGS. 1, 2. and 4, the baseball bat is formed concentric with the concentric growth rings of the tree limb.
[0023] FIG. 3 shows a cross section of a tree (100) showing an orientation of a baseball bat (1) that would be formed by the method of the present invention. The tree (100) includes a trunk (101) and a limb (102). The limb (102) has a center growth ring (110) running along its length at a center of the limb, as is shown in FIG. 3.
[0024] FIG. 5 is a perspective view of a baseball game bat formed by the method of the present invention. FIG. 8 is a perspective view of a baseball practice bat formed by the method of the present invention. The arrows in FIGS. 5 and 8 are representations of the densities of the baseball bats. Each arrow extends a varying length of the baseball bat to delineate sections that would have an equivalent weight if these sections were cylinders with identical diameters, as is the case with billets. Therefore, longer arrows and sections are required in areas of the limbs, billets, and baseball bats in less dense areas to each the weight represented by shorter arrows in more dense areas. Because of this density disparity, the smaller arrows nearer the handle and the knob of the baseball bat will have greater weight in identically sized sections in FIG. 5. Further, the longer arrows nearer the handle and knob of the baseball bat will a lesser weight in identically sized sections in FIG. 8. These sections constantly vary based on the orientation of the baseball bat with respect to how the limbs, billets, and baseball bats are harvested from the tree. As is shown in FIG. 7, if the limbs, billets, and baseball bats are harvested from the tree with the knob and handle closer to the trunk, then a baseball game bat will be produced with a center of gravity (CG; as indicated by the center line in FIG. 5) closer to the knob and handle, as is shown in FIG. 5. As is shown in FIG. 9, if the limbs, billets, and baseball bats are harvested from the tree with the barrel closer to the trunk, then a baseball practice bat will be produced with a center of gravity (CG; as indicated by the center line in FIG. 8) closer to the distal end of the baseball bat, as is shown in FIG. 8.
[0025] FIG. 6 is a perspective view of a tree (100) showing an orientation of a portion (1000) of a limb (102) to be harvested to form a baseball bat by the method of the present invention. As is depicted in FIG. 6, the portion (1000) to be harvested from the limb (102) does not include any of the tree's (100) trunk (101). In this manner, the entire tree (100) does not need to be harvested. This approach is much less wasteful and much more environmentally friendly than the traditional approach of felling an entire tree in order to make baseball bats.
[0026] FIG. 10 is a depiction of the method of the present invention. Step 1 (S1) requires identifying a desired tree (100). In most cases an ash tree of nearly 50 years in age is required to produce acceptable baseball bats. But trees of varying types and ages are contemplated in the present invention. Step 2 (S2) require procuring a tree limb absent any tree trunk. By harvesting only the tree limb (102) and leaving the tree trunk (101) (see: FIG. 6), the tree (100) will not need to be sacrificed to produce baseball bats of the present invention. Step 3 (S3) requires forming a cylindrical billet concentric with the tree limb's growth rings. As can be seen in FIGS. 1-4, the growth rings within the limb will not be bisected during fabrication of the billet, thus increasing the strength of the baseball bat of the present invention, as compared to the baseball bats of the prior art. Step 4 (S4) requires a determination of the intended use of the baseball bat. As is shown in FIGS. 5 and 7-9, the orientation of the limb, billet, and baseball bat within the lathe will be opposite for the baseball game bat shown in FIGS. 5 and 7 and for the baseball practice bat shown in FIGS. 8 and 9. Steps 5a and 6a (S5a and S6a) require for production of a baseball game bat that the billet be placed into a lathe with the denser portion of the billet at the baseball bat handle end of the lathe. Steps 5b and 6b (S5b and S6b) require for production of a baseball practice bat that the billet be placed into a lathe with the denser portion of the billet at the baseball bat barrel end of the lathe. By this technique and as is shown in FIG. 7, if the limbs, billets, and baseball bats are harvested from the tree with the knob and handle closer to the trunk, then a baseball game bat will be produced with a center of gravity (CG) closer to the knob and handle, as is shown in FIG. 5. As is shown in FIG. 9, if the limbs, billets, and baseball bats are harvested from the tree with the barrel closer to the trunk, then a baseball practice bat will be produced with a center of gravity (CG) closer to the distal end of the baseball bat, as is shown in FIG. 8. Step 7 (S7) requires forming a baseball bat concentric with the growth rings, as is shown in FIGS. 1, 2, and 4.
[0027] While preferred embodiments of the present invention have been described above, it is understood that variations and modification will be apparent to those skilled in the art, without departing from the scope and spirit of the present invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
