Rip fence with dual locking mechanism

A table saw comprising:

• a frame having an upper cutting surface, the upper cutting surface having an opening for a blade to extend through and having a front edge surface and a rear edge surface;
• a rail connected to the front edge surface, the rail having a slot extending longitudinally along an upper surface of the rail, and
• a rip fence slideably engaged to the table saw between various secured positions such that the rip fence is generally parallel to the blade, the rip fence comprising:
• an elongated casing extending between a front end proximate the front edge surface and a rear end proximate the rear edge surface;
• a handle having an upper edge wherein one end of the upper edge pivots relative the front end of the casing at one end of the upper edge;
• a rotatable cam having a first end and a second end;
• a movable link pivotally connected at one end to the first end of the cam and an opposing end pivotally connected at an opposing end of the upper edge of the handle;
• a first activation plate having an upper end and a lower end, with the lower end engaged towards the second end of the cam;
• a clamping plate having a passage formed towards one end and a lip extending from an opposing end, wherein a second end of the first activation plate extending through the passage and the lip being slideably positioned within the rail slot;
• an elongated rod movably supported by the casing wherein one end of a rod engages the upper end of the first activation plate;
• a second activation plate movably engaged at an upper end to a second end of the rod and wherein the second activation plate has a tab at a lower end, and
• wherein the handle is movable between a lower locked position such that the link pushes the cam against the upper end of the first activation plate thereby pushing the lip of the clamping plate in a secured position against the rail slot and the first activation plate pushes the rod against the second activation plate so that the tab is in a secured position relative the table saw and an upper released position such that the link pulls the cam away from the upper end of the first activation plate thereby pulling the lip into a released position within the rail slot and the cam pulls the rod away from the second activation plate so that the tab is in a released position relative the table saw.
