Patent ID: 7763091

Claim:
A distributed vacuum debris collector, comprising: a vacuum coupling for connection to a vacuum source; a vacuum reservoir coupled through said vacuum coupling to said vacuum source and having a cupped body defined by a solid base, an inlet base spaced therefrom, and side walls rising normal from said inlet base, said solid base and said inlet base defining a chamber therebetween for containing said vacuum; wherein said vacuum reservoir further comprises: a first interlocking container having sidewalls circumscribing an air space, an opening adjacent a first termination of said sidewalls and a solid bottom distal to said opening; and a second interlocking container for nesting within said first interlocking container having sidewalls circumscribing an air space, an opening adjacent a first termination of said sidewalls and a perforated bottom distal to said opening; said vacuum reservoir defined by said first interlocking container solid bottom, side walls and said second interlocking container perforated bottom; and inlet holes through said vacuum reservoir inlet base forming the primary inlet into said chamber having a variable density pattern with more inlet hole area per unit surface area adjacent to said side walls than at a center more distal from said side walls.
