ABSTRACT:
A safety device for a rocking arm saw includes a blade guard assembly which may be selectively mounted on a handle which rocks the saw blade for crosscutting operations or on a workpiece supporting surface for ripping operations. The blade guard assembly includes a guard housing substantially covering the portion of the blade which extends above the workpiece support surface and is pivotally mounted to the handle for displacing the blade by means of a first mounting arm. The blade guard is mounted on the workpiece support surface by a mounting arm having the opposite ends thereof respectively pivotally connected to the blade guard and a planar, upright support mounted on the supporting surface. The upright support is coplanar with the blade and possess a thickness no greater than that of the blade so as to pass through a cut produced by the blade when a workpiece is moved across the support surface and through the blade.
