Abstract
A supportive tray upstandingly supports an elongated resilient planar loop having convexly contoured reaming sides and an arcuate reaming arch. An inverted pipe bowl placed on and pressed downwardly on the arch deforms the convex sides into conforming engagement with the concavely formed bowl sides to perform a reaming function upon rotation of the bowl relative the loop to remove ash and dottle from the pipe bowl.
Claims1
A pipe reamer-capture tray for cleaning a pipe bowl comprising:
- a supportive tray having a bottom surface and upstanding peripheral walls for ash and dottle containment;
- a single, unitary, elongated resilient loop element formed of relatively stiff wire having a pair of convexly curved side portions smoothly joined by an arcuate arch portion, said side portions having distal ends;
- said loop element lying in a loop-defined fixed plane;
- supporting means having said distal ends of said side portions secured thereto for supporting said element on said bottom surface of said tray in upstanding relationship therewith and in said loop-defined fixed plane whereby said side and arch portions resiliently conform to the inner surface of a pipe bowl for reaming the same upon insertion therein and application of downward rotative force thereon;
- and said supporting means comprises a member having said distal ends secured thereto, fastener means for securing said member to said bottom surface.
