Abstract
A guide assembly, or rip fence, supported by guides of a table saw includes a clamping apparatus having locking mechanisms located at each end of the guide assembly. Each of the locking mechanisms is independently adjustable to provide accurate and repeatable positioning of the guide assembly with respect to the table and with respect to the saw blade with self-alignment and desired force. An adjustable locking self-alignment spring provides for self-alignment of the rip fence with respect to the blade.

A guide assembly for aligning a workpiece on a table of a saw device, comprising:
- an alignment member having a first end and a second end;
- a first lock mechanism, located at the first end of the alignment member, to secure the first end to the saw device, the first lock mechanism being adjustable to apply a self-alignment feature;
- a second lock mechanism, located at the second end of the alignment member, to secure the second end to the saw device, the second lock mechanism being adjustable to apply an adjustable clamping force to the saw device;
- and
- a linkage operably coupled to the first lock mechanism and to the second lock mechanism, wherein movement of the first lock mechanism causes the linkage to move the second lock mechanism into engagement with the saw device to secure first end and the second end to the saw device.
A power saw comprising:
- a blade;
- a table including an opening configured to receive the blade;
- and
- an alignment member provided on the table, the alignment member having a first lock mechanism located at a first end of the alignment member and a second lock mechanism located a second end of the alignment member, wherein the first lock mechanism is adjustable to a apply an adjustable self-alignment feature and the second lock mechanism is adjustable to apply an adjustable clamping force to the rip fence.
