ABSTRACT:
A saw blade guard for a table saw or the like includes a flat blade guard arm which is coplanar with the circular cutting blade and has a thickness no greater than that of the blade. The guard includes a yoke portion mounted on a bearing on the blade arbor below the table such that the yoke is allowed to rotate independently of the rotation of the arbor. The guard arm is semicircular in shape and extends through the kerf in the workpiece produced by the saw blade and down through the blade slot in the table to a point adjacent the yoke. The yoke includes a radially radial extension which supports the arm below the table. A roller mounted on the outer free extremity of the guard arm above the table is engaged by the leading edge of the workpiece and forces the arm to rotate a sufficient amount to expose the workpiece to the blade. A counterweight mounted on the yoke below the table biases the guard arm to normally rotate into covering relationship to the blade such that the roller bears against the workpiece at all times.
