  • Patent number: 5481806
    Abstract: A Tongue attachment for a portable electric circular saw equipped with a lower retractable or pivoting blade guard in which in a closed position the guard covers most of the blade, to a retracted position in which the cutting edge is exposed to material for cutting. An interior wall of the lower guard of such conventional saws has a quarter-circular leading edge that serves as a point of sliding contact with the work piece as the saw cuts through the piece. An opposite, exterior wall of such conventional guards lacks a similar leading edge. Consequently, the lower guard of such saws of conventional design have a tendency to catch the concave wall of the face of the guard on the material being worked. This stops the saw from proceeding until the handle on the guard is used to lift it from this catching position. The Tongue attachment completely eliminates this problem. In an alternative embodiment, such a tongue is made an integral part of a lower guard.
