Abstract
A carpentry block is provided to support a remote end of a board or work piece to be cut with a table saw or chop saw. The block has a triangular body which can be positioned on any base to define three different heights to support the remote work piece end. The block can also be positioned on the one end to define a fourth height for work piece support. An extension member can be added to the block to provide additional heights with the block, the outer end of the work piece is level with the saw table, thereby assuring an accurate cut of the work piece by the saw blade.
Claims
1. A block for supporting one end of a board being cut with a saw, comprising: a unitary body substantially triangular in cross section so as to have three base surfaces and three board surface each being opposite and parallel to a respective one of the board surfaces, and the board surfaces being formed by truncated tips of the body to define heights from each base surface to the respective opposite parallel board surface; the heights varying for each base surface; and wherein the body is selectively set on one of the base surfaces to support the end of the board on the respective opposite board surface.
2. The block of claim 1 wherein the body has opposite ends defining an additional height to support the one end the board when the body is set on one of the ends.
3. The block of claim 1 further comprising an extension member mounted on the body to increase one of the heights.
4. The block of claim 3 wherein the block and the extension member have mating couplers.
5. The block of claim 3 wherein the block and the extension member have a male and female connection.
6. The block of claim 3 wherein the body has a notch on each board surface and the extension member has a tab for retentive engagement in the notch.
7. The block of claim 1 wherein the body has a recess for manual gripping.
8. A support block for a workpiece being cut by a saw blade, the workpiece being supported by a deck adjacent the saw blade and having a remote end spaced from the deck, the support block, comprising: first, second and third bases, each adapted to rest upon the floor or ground; first, second and third top edges opposite and parallel to the first, second and third bases, respectively, each edge being adapted to support the remote end of the workpiece during cutting; and the block having a different height from each base to the opposite parallel top edge; wherein the body is rotatable about a single axis to selectively position each of the three top edges in a substantially horizontal plane with the deck for supporting the workpiece remote end.
9. The support block of claim 8 wherein the first base and the first edge define a first height for the block, the second base and the second edge define a second height for the block, and the third base and the third edge define a third height for the block; and the first, second and third heights being different from one another.
10. The support block of claim 9 further comprising opposite ends which define a fourth height therebetween, and the fourth height being different than the first, second, and third heights.
11. The support block of claim 8 wherein the first, second and third bases form a triangular cross section for the support block with truncated points formed by the first second and third top edges.
12. The support block of claim 8 further comprising an extension member mounted on the body to increase one of the heights.
13. The support block of claim 12 wherein the block and the extension member have mating couplers.
14. The support block of claim 12 wherein the block and the extension member have a male and female connection.
15. The support block of claim 12 wherein the body has a notch on each edge and the extension member has a tab for retentive engagement in the notch.
16. The support block of claim 8 wherein the body has a recess for manual gripping.
17. A method of cutting an elongated workpiece, comprising: supporting the workpiece on a saw table in front of a sawblade whereby an end of the workpiece extends beyond the saw table; supporting the end of the workpiece with a triangular-shaped block having three sides and opposite parallel ends, and being positioned between the saw table and the end of the workpiece; rotating the block about a longitudinal axis to one side of the block or about a lateral axis to one end of the block to adjust the height of the end of the workpiece to a position substantially level with the saw table.
18. The block of claim 1 wherein the base surfaces and the board surfaces form three pairs of parallel edges for the body.
19. The block of claim 1 wherein the body is non-symmetrical.
20. The block of claim 1 wherein each base surface has a length greater than the height to the opposite board surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(8) The carpentry block of the present invention is designated in the drawings by the reference numeral 10. In one embodiment, the block 10 is formed from molded plastic or composite material, has a unitary construction, has no moving parts, and with no assembly required.
(9) The block 10 has a triangular shape as shown in
(10) The block 10 can be rotated so as to position any one of the faces 12, 14, or 16 upon the ground or floor 30 at a distance spaced apart from the saw table or deck 32 having a saw blade 34, so as to support an outer or remote end 35 of a board or workpiece 36 to be cut. The orientation of block 10 is selected such that the height 24, 26, or 28 substantially matches the height of the saw table or deck 32 such that the board or work piece 36 is supported in a substantially horizontal position, with the board or work piece 36 being flat on the saw table or deck 32. Such support of the free end 35 of the board or work piece 36 will produce an accurate cut by the saw blade 34 at the inner workpiece end 38, since the opposite ends 35, 38 of the work piece 36 are substantially level or horizontal.
(11) The block 10 also has opposite ends 40, 42 which are spaced apart so as to define a fourth height 44. The height 44 can be any desired height, such as 6 inches shown in
(12) Thus, the block 10 provides four height options for supporting the board or work piece 36 while the workpiece is being cut by the saw. Height indicia may be provided on each of the edges 18, 20, 22, as seen in
(13) Preferably, the block 10 is hollow, with cutouts or recesses 46 which allow for easy pickup and gripping of the block 10. This construction also makes the block 10 lightweight.
(14) The block 10 also accommodates fluctuations in the work piece, such as board warpage, to maintain the board or work piece 36 flat on the saw deck 32.
(15) In use, the block 10 supports the outer end of 35 the work piece 36, opposite the saw blade 34, thus providing safer working conditions for the saw operator. For example, when cutting stair railing pickets for a spindle type stair hand railing, the saw user has to hold down the top part of the spindle to the saw deck. When cutting the angled top end of the picket, or shaving off a little of the end, in the conventional method without the block 10, one hand holds the end to be cut at a location very close to the blade 34, because there is nothing supporting the other end of the spindle. With the block 10 supporting the outer end of the picket, the operator can move their hand further from the blade 34 to a safer position, while the picket is supported on the deck 32 and on the block 10 for an accurate cut.

(18) The invention has been shown and described above with the preferred embodiments, and it is understood that many modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objectives.
