Stop rule for circular saw benches

A fence ruler for a circular saw table, said fence ruler comprising:

• a profiled hollow body extending longitudinally and having an essentially rectangular cross-section, the profiled hollow body being mountable onto the saw table in two different orientations, said body having one side formed as a guiding leg extending from the profiled hollow body, the guiding leg comprising a guiding ruler formed on its outer edge, the guiding ruler being suited for use with a lower work piece and extending to provide a surface essentially perpendicular to the saw table when the guiding leg lays on the saw table,
• wherein a slide is disposed in the hollow space extending longitudinally within the profiled hollow body, the slide being slidable within the profiled hollow body from the outside of the hollow space, and
• wherein a first catch and a second catch protrude from the slide, the second catch moving through a second longitudinal slot in the profiled hollow body and protruding to the outside of the profiled hollow body through an opening slot in the guiding ruler for advancing a workpiece when the guiding legs lays on the saw table,
• the first catch extends from a first longitudinal slot situated near the edge of the guiding leg closer to the saw table and opposite the guiding ruler for advancing a workpiece when the guiding leg is reoriented upwardly from the saw table, the two catches being disposed at an angle of approximately 90° to each other.
