Dust collection attachment

Abstract

A dust collection attachment is disclosed that is adapted to be coupled to a base. A barrier coupled to the pan includes a plurality of bristles that create an opening to the pan between the base and the barrier in order to prevent debris generated by a tool from passing through the barrier, yet allowing passage of the tool through the barrier.

1 . A dust collection attachment adapted to be coupled to a base to guide debris, comprising:
 a pan adapted to be coupled to the base; and   a barrier coupled to the pan that includes a plurality of bristles that create an opening to the pan between the base and the barrier to prevent debris generated by a tool from passing through the barrier.   
     
     
         2 . The dust collection attachment of  claim 1  wherein the barrier is adjustable to a plurality of positions with respect to the pan. 
     
     
         3 . The dust collection attachment of  claim 1  wherein the plurality of bristles include a main portion spaced apart from the base to create the opening to the pan and two side portions angled toward the base. 
     
     
         4 . The dust collection attachment of  claim 1  and further comprising an outlet coupled to the pan, the outlet being adapted to be coupled to a tube. 
     
     
         5 . The dust collection attachment of  claim 4  wherein the pan further includes a funnel, a first aperture and a second aperture, the first and second apertures adapted to receive a fastener for coupling the pan to the base, wherein the first aperture and the second aperture are positioned on opposite sides of the funnel and wherein the funnel directs debris from the opening to the outlet. 
     
     
         6 . The dust collection attachment of  claim 1  and further comprising a cover adjustable with respect to the barrier to at least partially cover the opening. 
     
     
         7 . A combination, comprising:
 a base having a jig for use with a cutting tool;   a dust collection attachment having a pan mounted to the base and a barrier coupled to the pan having a plurality of bristles including a portion spaced apart from the base to guide debris generated by the cutting tool to the pan.   
     
     
         8 . The combination of  claim 7  wherein the plurality of bristles allow the cutting tool to pass therethrough and prevents debris generated by the cutting tool from passing therethrough. 
     
     
         9 . The combination of  claim 7  wherein the base includes a clamping mechanism adapted to hold the dust collection attachment relative to the base. 
     
     
         10 . The combination of  claim 9  wherein the clamping mechanism includes first and second cams positioned on opposite sides of a lever and wherein the dust collection attachment includes first and second support posts providing load paths between the first and second cams and the base. 
     
     
         11 . The combination of  claim 9  wherein the clamping mechanism is further adapted to hold a first work piece relative to the base and wherein the base includes a second clamping mechanism adapted to hold a second work piece orthogonal to the first work piece. 
     
     
         12 . The combination of  claim 7  wherein the pan further includes a first aperture and a second aperture adapted to receive a first fastener and second fastener, respectively, and a funnel wherein the first aperture and the second aperture are positioned on opposite sides of the funnel. 
     
     
         13 . The combination of  claim 7  and further comprising a vacuum and a tube connecting the vacuum and the dust collection attachment. 
     
     
         14 . A method of guiding debris from a workpiece generated by a cutting tool, comprising:
 providing a barrier having an opening spaced apart from a base;   allowing the cutting tool to pass through the barrier while preventing debris from passing through the barrier.   
     
     
         15 . The method of  claim 14  wherein the barrier includes a plurality of bristles. 
     
     
         16 . The method of  claim 14  and further comprising:
 providing a pan coupled to the barrier to guide debris from the opening to an outlet. 
 
     
     
         17 . The method of  claim 16  and further comprising:
 clamping the pan and barrier to the base using a fastener passing through an aperture in the base. 
 
     
     
         18 . The method of  claim 17  and further comprising:
 coupling a jig to the base to guide the cutting tool; and 
 positioning the barrier such that the opening is between the jig and barrier. 
 
     
     
         19 . The method of  claim 18  and further comprising:
 coupling a tube to the outlet; and 
 coupling a vacuum to the tube to provide suction to the outlet. 
 
     
     
         20 . The method of  claim 14  and further comprising:
 providing a cover to at least partially cover the opening.
