Abstract

The invention relates to a dust retaining and filtering device which can be attached to a dust generating tool, for controlling the spread of dust and other particulate matter generated by grinding, sanding, polishing, burnishing and buffing devices. The device comprises a resilient skirt which curves outwardly along its bottom edge; a filter extending along the length of the skirt; means for mounting the filter along the length of the skirt and attachment means for securing the device to the dust generating tool.

Claims

1. A device for trapping particulate matter generated during operation of a surface abrasion apparatus, comprising:

a resilient wall member with a lower, surface engaging lip portion;

a filter adjacent said wall member;

retaining means comprising a plurality of hook and pile fasteners for securing said filter to said wall member;

attachment means for detachably securing said wall member to said surface abrasion apparatus.

3. A device as claimed in claim 1 wherein said surface abrasion apparatus is a dust producing tool.

4. A device as claimed in claim 1 wherein said surface abrasion apparatus is a floor sanding apparatus.

5. A device as claimed in claim 4 wherein said dust producing tool is a floor polishing apparatus.

6. A device as claimed in claim 4 wherein said dust producing tool is a floor burnishing apparatus.

7. A device as claimed in claim 4 wherein said dust producing tool is a floor buffing machine.

8. A device as claimed in claim 1 wherein said filter is of sponge-like material.

9. A device as claimed in claim 8 wherein said filter comprises reticulated polyurethane foam.

2. An apparatus for retaining the dust generated by a tool selected from the group comprising grinding, sanding, polishing, burnishing and buffing devices;

and adapted for use in combination with said devices, comprising a flexible skirt which curves outwardly along its bottom edge;

a filter extending along the length of the skirt;

means for mounting the filter along the length of the skirt and attachment means for securing the apparatus to the tool.
