Chamber cleaning device

Abstract

A chamber cleaning device may include an elongated body having a first end and a second end. A head may be coupled to the first end, and a motivator may be movably coupled to the second end. The motivator, body, and head may be aligned with a central axis. Preferably, four fingers may be movably coupled to the head. An end cap may be operably coupled to the motivator, and the end cap may have a beveled edge. The motivator may be operable to move the fingers towards and away from the central axis by drawing the beveled edge against the finger so that the beveled edge presses the finger away from the central axis.

What is claimed is: 
     
         1 . A chamber cleaning device, the device comprising:
 an elongated body having a first end and a second end;   a head coupled to the first end;   a motivator movably coupled to the second end, the motivator, body, and head aligned with a central axis; and   a finger movably coupled to the head, wherein the motivator is operable to move the finger both towards and away from the central axis.   
     
     
         2 . The device of  claim 1 , wherein the finger comprises length dimension between 0.27 inches to 0.33 inches. 
     
     
         3 . The device of  claim 1 , wherein the finger is movably coupled to the head via a hinge. 
     
     
         4 . The device of  claim 1 , wherein the finger is movably coupled to the head via a wing, the wing forming a living hinge. 
     
     
         5 . The device of  claim 1 , wherein the finger comprises a scraping edge. 
     
     
         6 . The device of  claim 5 , wherein the scraping edge is made of a polymer material. 
     
     
         7 . The device of  claim 1 , wherein the head comprises two fingers. 
     
     
         8 . The device of  claim 7 , wherein each finger is movably coupled to the head via a hinge. 
     
     
         9 . The device of  claim 1 , further comprising an end cap operably coupled to the motivator, the end cap having a beveled edge, wherein the motivator is operable to move the finger away from the central axis by drawing the beveled edge against the finger so that the beveled edge presses the finger away from the central axis. 
     
     
         10 . The device of  claim 9 , wherein the motivator is operably coupled to the end cap via a transfer bar, and wherein the end cap is movably coupled to the transfer bar with threading. 
     
     
         11 . The device of  claim 9 , wherein the end cap comprises a cap guide for engaging with the head to prevent the end cap from rotating relative to the head. 
     
     
         12 . A chamber cleaning device, the device comprising:
 an elongated body having a first end and a second end;   a head coupled to the first end;   a motivator movably coupled to the second end, the motivator, body, and head aligned with a central axis; and   a finger movably coupled to the head via a hinge, the finger comprising a scraping edge, wherein the motivator is operable to move the finger both towards and away from the central axis.   
     
     
         13 . The device of  claim 12 , wherein the finger comprises length dimension between 0.27 inches to 0.33 inches. 
     
     
         14 . The device of  claim 12 , wherein the finger is movably coupled to the head via a wing, the wing forming a living hinge. 
     
     
         15 . The device of  claim 12 , wherein the head comprises two fingers. 
     
     
         16 . The device of  claim 15 , wherein each finger is movably coupled to the head via a hinge. 
     
     
         17 . The device of  claim 12 , wherein the scraping edge is made of a polymer material. 
     
     
         18 . The device of  claim 12 , further comprising an end cap operably coupled to the motivator, the end cap having a beveled edge, wherein the motivator is operable to move the finger away from the central axis by drawing the beveled edge against the finger so that the beveled edge presses the finger away from the central axis. 
     
     
         19 . The device of  claim 18 , wherein the motivator is operably coupled to the end cap via a transfer bar, and wherein the end cap is movably coupled to the transfer bar with threading. 
     
     
         20 . The device of  claim 18 , wherein the end cap comprises a cap guide for engaging with the head to prevent the end cap from rotating relative to the head.
