ABSTRACT:
A saw guard system adapted to be mounted on the headstock quill of a multipurpose woodworking tool includes a rear portion adapted to be clamped to the headstock quill, a front portion which forms a pocket with the rear portion and is adjustable so that the pocket size can be varied to accommodate rotary tools of varying thicknesses, and an exhaust port communicating with the pocket and having an outer end adapted to be attached to a vacuum hose. The rear portion supports a riving knife adapted to extend above an associated saw table and which includes an upper saw guard. The riving knife is positioned in a common plane with a rotary tool mounted on the quill, and is capable of remaining closely adjacent to the rotary tool regardless of table position or quill extension. An anti-kickback device includes a finger having a downwardly-extending point and is connected to the riving knife by a pair of link arms so that the horizontal orientation of the finger remains constant regardless of its elevation relative to the riving knife. To facilitate retention of dust in the pocket, as well as its removal through the port, the front portion includes a transverse channel at its lower end communicating with the port, the rear portion includes a deflector plate above the port, and the port is skewed relative to the front portion and is located at a downstream side of the pocket.
