  • Exhaust-driven sawdust venting attachment for a sawmill
    Patent number: 5953973
    Abstract: An exhaust-driven sawdust venting attachment for a sawmill provides a curved conduit portion attachable to the protective blade cover of the sawmill. A first exhaust inlet, carried by the curved conduit portion, supplies a stream of exhaust gasses that transports sawdust into a straight conduit portion. A second exhaust inlet carried by the straight conduit portion supplies a stream of exhaust gasses that transports sawdust out a vent opening some distance from the sawmill. As a result, sawdust does not tend to accumulate in the area of the saw blade.
