  • Patent number: 6154919
    Abstract: A system for collecting sawdust generated by a woodworking implement such as a table saw includes a funnel for directing sawdust from the saw to one end of a first hose, the other end of which communicates with a box-like structure having side and top walls and an open lower end. The interior of the box is divided into first and second compartments by a first portion of a baffle having edge portions positioned in grooves in opposing surfaces of two of the side walls of the box, the other two side walls having openings through which the other end of the first hose and one end of a second hose communicate with the first and second compartments, respectively. The box is affixed to the lid of a container in which the sawdust is collected. The open lower end of the box communicates with the interior of the container through an opening in the lid. The box is affixed to the lid by fasteners extending through strips surrounding the lid opening and through the lid, into the lower edges of the box side walls.
