Title: Dust collection port for use with a saw

Abstract: A dust collection port for a circular saw is formed on the upper rear end of a blade guard. A spring biased door pivotally moved between a closed position and an open position is provided over the port. The guard includes exit ribs and return ribs in the region of the port where the ribs direct the flow of the dust formed by the saw blade. The door includes ribs on the underside surface to secure a hose in the port when the door is in the open position. When the door is in the open position, dust flows through cavity formed by the guard into the exit ribs and into a hose inserted into the port. In the closed position, the dust flows through the exit ribs and into the return ribs to exit through the open lower end of the guard.
