Abstract
A saw table includes a clamping mechanism for clamping a work piece on the saw table. The clamping mechanism includes a clamping bar having a first end and a second end. A longitudinal axis is defined between the first and second ends. A first pivoting arm is operatively connected to one of the ends of the clamping bar to support the clamping bar for rotation about a pivot axis. A biasing device biases the clamping bar about the pivot axis to clamp the work piece between the clamping bar and a table base.
Claims20
A saw table comprising:
- a table base having a first base end and a second base end;
- a clamping bar having a first end and a second end defining a longitudinal axis therebetween;
- a first track supported by said table base and extending parallel to said longitudinal axis between said first and second base ends and spaced from said table base for supporting a saw cradle;
- a second track extending parallel to said first track and spaced from said table base;
- a first track support and a second track support mounting said first track on said table base at said respective first and second base ends and spaced from said table base and with said second track mounted on said first and second track supports;
- a pivoting arm operatively connected to said first end of said clamping bar to pivotally support said clamping bar at said first base end of said table base for pivotal movement about a pivot axis parallel to said longitudinal axis;
- said pivoting arm is pivotally mounted on said track support and comprises:
- a socket for receiving said end of said clamping bar with said socket including an end wall extending transverse to said longitudinal axis for abutting and restricting movement of said end of said clamping bar along said longitudinal axis,
- a lever wall extending transversely to said longitudinal axis from said socket to said pivot axis;
- a peripheral housing wall extending parallel to said longitudinal axis and transversely from said socket and said lever wall with said housing wall extending beyond said lever wall to define an opening between said lever wall and said housing wall;
- and
- a cover extending parallel to said lever wall and closing said housing wall;
- and
- a spring biasing said clamping bar about said pivot axis toward said table base to clamp a work piece between said clamping bar and said table base and resisting pivotal movement of said clamping bar in the opposite direction about said pivot axis, said spring extending through said opening of said pivoting arm between said lever wall and said track support.

- a pivoting arm operatively connected to said clamping bar to pivotally support said clamping bar on said table base for pivotal movement about a pivot axis parallel to said longitudinal axis;
- said pivoting arm is pivotally coupled to said table base and includes a lever wall extending transversely to said longitudinal axis, a peripheral housing wall extending parallel to said longitudinal axis and transversely from said lever wall to define an opening between said lever wall and said housing wall, and a cover closing said housing wall;
- and
- a biasing device biasing said clamping bar about said pivot axis toward said table base to clamp a work piece between said clamping bar and said table base and resisting pivotal movement of said clamping bar in the opposite direction about said pivot axis, said biasing device disposed between said cover, said lever wall, and said housing wall and extending through said opening of said pivoting arm between said lever wall and said track support.
