1. An optical alignment system for a table saw, comprising:
- a support device for supporting the optical alignment system with respect to a kerf having a first and a second side, said kerf created in a workpiece by operation of rotating blade included in a table saw;
at least one optical emitting device mounted in the support device, said at least one optical emitting device for projecting a first optical indicator and a second optical indicator; and
an alignment devices coupled to the at least one optical emitting device, the alignment device being configured for adjusting the alignment of the projected first and second optical indicators with respect to the kerf, wherein the at least one optical emitting device is arranged and configured to project the first and second optical indicators substantially in alignment with the first and second sides of the kerf.

Abstract
The present invention is directed to an optical alignment system for table saws. In an aspect of the invention, an optical alignment system includes a support for positioning the system so that a first optical indicator and a second optical indicator are projected by at least one emitting device included in the system. An alignment device is further included in the system to permit adjustable alignment of the first and the second optical indicators individually with respect to one of a first side and a second side of a kerf created in a workpiece.

21. A table saw, comprising:
-
a support surface with an aperture therethrough, for supporting a workpiece;
a beveling cutting device adjustably extending through the support surface aperture, said cutting device for cutting a workpiece, whereby operation of the cutting device in the workpiece results in the formation of a kerf having a first and a second side in the workpiece;
a first optical emitting device adjustably coupled to the table saw to project a first optical indicator substantially aligned with the first side of a kerf; and
a second optical emitting device adjustably coupled to the table saw to project a second optical indicator substantially aligned with the second side of the kerf, wherein the first and the second optical emitting devices are configured so as to bevel with the cutting device, such that said first optical indicator and said second optical indicator are projected to substantially indicate the first and second sides of the kerf. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
