Abstract
A dust collection system designed for a table saw is disclosed. The dust collection system includes a dust shroud and dust shield to channel dust generated by a blade as it cuts wood or other material. The dust shroud includes fins and walls to “peel” dust and air off a spinning blade and direct the dust and air downward. The dust shroud encloses the lower front portion of a blade.
Claims17
A table saw comprising:
- a table defining a substantially horizontal work surface, where the table has a front;
- a planar, circular blade that extends at least partially above the work surface, where the blade has a perimeter with a forward-most point toward the front of the table, where the blade spins about an axis of rotation, where the blade has planar sides and where the blade moves between a fully elevated position and a fully lowered position;
- a motor to drive the blade;
- and
- a dust shroud that covers at least a portion of the blade beneath the table, where the dust shroud includes a front wall positioned between the front of the table and a first line extending perpendicular to the work surface and passing through the axis of rotation of the blade, a side wall with a surface adjacent the blade, and a fin extending perpendicularly out toward a planar side of the blade from the surface of the side wall, where at least a portion of the fin is between the first line and a second line extending perpendicular to the work surface and passing through the forward-most point of the blade's perimeter, and where at least a portion of the fin extends below the lowest point on the perimeter of the blade below the table with the blade in the fully elevated position.

A table saw comprising:
- a table defining a work surface, where the table has a front, and where the table has an opening;
- a planar, circular blade that extends at least partially above the work surface and that rotates about an axis of rotation;
- an insert in the opening in the table, where the insert has a thickness, a top surface substantially coplanar with the work surface, and a bottom surface above the axis of rotation;
- a motor to drive the blade;
- and
- a dust shroud that includes a portion positioned between the front of the table and the blade, where the portion is below the work surface, and where the portion extends into the thickness of the insert.
