Abstract

A taper jig that provides a woodworker with multifunctional use for orientating and maintaining a workpiece in order to make a tapered cut in a workpiece at desired incremental angles. The taper jig includes a first track and a second track that operably engages the first track wherein the second track is pivotably moveable relative to the first track. The taper jig also includes at least one measurement scale assembly that operably secures the first track and the second track to one another at a predetermined angle. The taper jig also includes at least one clamping handle assembly that operably engages one of the first track and the second track, wherein the at least one clamping handle assembly being adapted to clamp a workpiece. The taper jig may also include a first sled and a second sled that operably engage with the first and second tracks.

First claim

What is claimed:

1. A taper jig, comprising:
a first track;
a second track operably engaging the first track wherein the second track is pivotably moveable relative to the first track; and
at least one measurement scale assembly operably securing the first track and the second track to one another at a predetermined angle;
wherein the at least one measurement scale assembly further comprises: an indexer having a set of measurement teeth defining a set of angles;
and a selector having at least one selector tooth operable to selectively engage the set of measurement teeth and set the predetermined angle between the first track and the second track.

2. The taper jig of claim 1 , wherein the first track and the second track are arranged in a same plane, and each of the first track and the second track has an outer surface and an inner surface, and when the first track and the second track pivot relative to one another, the inner surfaces move one of towards and away from one another.

3. The taper jig of claim 1 , wherein the first track further comprises a front end, a rear end, a first top channel extending from the front end of the first track to the rear end of the first track, and an opposing first bottom channel extending from the front end of the first track to the rear end of the first track.

4. The taper jig of claim 3 , wherein the second track further comprises a front end, a rear end, a second top channel extending from the front end of the second track to the rear end of the second track, and an opposing second bottom channel extending from the front end of the second track to the rear end of the second track.

5. The taper jig of claim 4 , further comprising:
at least one clamping handle assembly operably engaging one of the first track and the second track, said at least one clamping handle assembly being adapted to clamp a workpiece; wherein the at least one clamping handle assembly is selectively operably engageable in one of the first top channel and the second top channel.

6. The taper jig of claim 1 , wherein each of the first track and the second track has a front end and a rear end, wherein a channel is defined in each of the first track and the second track and each of the channel extends from each of the front end to each of the rear end, and wherein the at least one measurement scale assembly is operably engaged with the channel of the first track and with the channel of the second track.

7. The taper jig of claim 1 , further comprising: a push plate selectively operably engaging either of the first track and the second track.

8. The taper jig of claim 1 , wherein the set of angles defines a range of from zero degrees up to seven degrees arranged in one-quarter degree increments.

9. The taper jig of claim 1 , wherein the set of angles defines a range of from zero degrees up to fifteen degrees arranged in one-half degree increments.

10. The taper jig of claim 5 , wherein the at least one clamping handle assembly comprises:
a handle;
a threaded shaft operably engaged with the handle, said threaded shaft being adapted to engage with a woodworking tool; and
a clamp block operably engaged with the threaded shaft, said clamp block being adapted to apply a clamping force to a workpiece.

11. The taper jig of claim 10 , wherein the handle and the clamp block interlockingly engage with one another.

12. The taper jig of claim 10 , wherein the clamp block is selectively movable between a first orientation and a second orientation.

13. The taper jig of claim 1 , wherein each of the first track and the second track has a front end and a rear end, wherein a channel is defined in each of the first track and the second track and each of the channel extends from each of the front end to each of the rear end, and wherein the taper jig further comprises:
a span clamp assembly extending between the channel in the first track and the channel in the second track, said span clamp assembly adjustably securing the first track and the second track to one another.

14. The taper jig of claim 13 , wherein the at least one measurement scale assembly sets the predetermined angle in a first range of angles, and wherein the span clamp assembly sets the predetermined angle in a second range of angles outside of the first range of angles.

15. The taper jig of claim 4 , further comprising:
a first sled operably engaged with the first bottom channel of the first track by a first set of locking mechanisms; and
a second sled operably engaged with the second bottom channel of the second track by a second set of locking mechanisms.

16. The taper jig of claim 1 , further comprising an expansion assembly, the expansion assembly comprising:
a first expansion track operably engaged to the first track; and
a second expansion track operably engaged to the second track.

17. A method of cutting a workpiece using a taper jig, comprising:
engaging a first track of a taper jig with a second track of the taper jig by pivotably moving the second track relative to the first track;
moving the first track of the taper jig and the second track of the taper jig to a predetermined angle relative to one another via at least one measurement scale assembly;
securing the first track and the second track to one another at the predetermined angle via the at least one measurement scale assembly;
operably engaging at least one clamping handle assembly with one of the first track and the second track;
clamping the workpiece to the one of the first track and the second track with the at least one clamping handle assembly;
cutting the workpiece at the predetermined angle via a cutting blade;
providing an indexer on the at least one measurement scale assembly and providing a set of measurement teeth on the indexer;
providing a selector on the at least one measurement scale assembly and providing at least one selector tooth on the selector; and
selectively engaging the at least one selector tooth with the set of measurement teeth to set the predetermined angle between the first track and the second track.

18. The method of claim 17 , further comprising:
utilizing the at least one measurement scale assembly to set the predetermined angle in a first range of angles.

19. The method of claim 18 , further comprising providing the indexer on the at least one measurement scale assembly having a first set of angles thereon that are in the first range of angles, and the first set of angles is from zero degrees up to seven degrees arranged in one-quarter degree increments.

20. The method of claim 18 , further comprising providing the indexer on the at least one measurement scale assembly with a first set of angles thereon that are in the first range of angles, and the first set of angles is from zero degrees up to fifteen degrees arranged in one-half degree increments.

21. The method of claim 18 , further comprising:
disengaging the at least one measurement scale from one or both of the first track and the second track;
engaging a span clamp assembly between the first track and the second track; and
utilizing the span clamp assembly to set the predetermined angle in a second range of angles, wherein the second range of angles is outside of the first range of angles.

22. The method of claim 17 , further comprising:
defining a first channel in the first track, wherein the first channel extends between a front end and a rear end of the first track;
defining a second channel in the second track, wherein t
