Saw enclosure construction

In a table saw of the type having a saw blade carried by a rotor shaft mounted beneath a work table through which the saw blade projects upwardly to saw a work piece supported on the table;

• walls forming sawdust removal housing means enclosing that portion of the saw blade beneath the work table;
• the housing means having first and second side walls;
• the saw blade portion in the housing being located parallel with the side walls and closer to the first side wall than to the second, thereby forming narrow inlet chamber means on one side and wide exit chamber means on the other side of the saw blade;
• the housing means being formed with inlet port means adjacent the work table communicating with the inlet chamber means and being formed with exit port means communicating with the exit chamber means;
• the housing means walls forming the inlet port means being open at the top adjacent the work table;
• felt sealing means mounted within the wide exit chamber means at the top of the housing walls contacting the exit chamber face of the saw blade to seal the wide exit chamber means against the direct entry of exterior air;
• suction means connected with the exit port means;
• and the cross-sectional area of the inlet port means being approximately equal to the cross-sectional area of the exit port means, whereby the suction means induces a flow of high velocity air through the inlet chamber means from the inlet port means and thence across the saw blade teeth to enter the exit chamber means from which the air is exhausted by the suction means through the exit port means.
