Brush gauge and related methods

Abstract

A brush gauge includes a stepped barb and an arcuate ledge. The stepped barb and the arcuate ledge partially define an aperture.

What is claimed is: 
     
         1 . A brush gauge, comprising:
 a stepped barb; and   an arcuate ledge, wherein the stepped barb and the arcuate ledge partially define an aperture.   
     
     
         2 . The brush gauge of  claim 1 , wherein the stepped barb is connected to the arcuate ledge by a sloped wall. 
     
     
         3 . The brush gauge of  claim 1 , wherein the arcuate ledge is a shoulder defined between a top arcuate wall and a bottom arcuate wall. 
     
     
         4 . The brush gauge of  claim 1 , wherein the stepped barb comprises
 a stepped wall,   a top sloped wall, and   a bottom sloped wall.   
     
     
         5 . The brush gauge of  claim 1 , wherein the stepped barb and the arcuate ledge extend into the aperture. 
     
     
         6 . The brush gauge of  claim 1 , further comprising an end wall partially defining the aperture opposite the arcuate ledge. 
     
     
         7 . The brush gauge of  claim 1 , wherein the aperture is formed of a top opening in communication with a bottom opening, the top opening being larger than the bottom opening. 
     
     
         8 . A brush gauge, comprising:
 an arcuate ledge;   a first stepped barb connected to the arcuate ledge; and   a second stepped barb connected to the arcuate ledge.   
     
     
         9 . The brush gauge of  claim 8 , wherein the first stepped barb is opposite the second stepped barb. 
     
     
         10 . The brush gauge of  claim 8 , wherein:
 the first stepped barb is connected to the arcuate ledge by a first sloped wall, and   the second stepped barb is connected to the arcuate ledge by a second sloped wall.   
     
     
         11 . The brush gauge of  claim 8 , wherein the arcuate ledge is a shoulder defined between a top arcuate wall and a bottom arcuate wall. 
     
     
         12 . The brush gauge of  claim 8 , wherein the arcuate ledge, the first stepped barb, and the second stepped barb partially define an aperture. 
     
     
         13 . The brush gauge of  claim 8 , wherein:
 the first stepped barb comprises a first stepped wall, a first top sloped wall, and a first bottom sloped wall, and   the second stepped barb comprises a second stepped wall, a second top sloped wall, and a second bottom sloped wall.   
     
     
         14 . The brush gauge of  claim 8 , further comprising an end wall connected to the first stepped barb and the second stepped barb and opposite the arcuate ledge. 
     
     
         15 . A brush gauge, comprising:
 a body defining an aperture and comprising
 a stepped barb extending into the aperture, and 
 an arcuate ledge extending into the aperture. 
   
     
     
         16 . The brush gauge of  claim 15 , wherein the stepped barb is connected to the arcuate ledge by a sloped wall. 
     
     
         17 . The brush gauge of  claim 15 , wherein the arcuate ledge is a shoulder defined between a top arcuate wall and a bottom arcuate wall. 
     
     
         18 . The brush gauge of  claim 15 , wherein the stepped barb comprises
 a stepped wall,   a top sloped wall, and   a bottom sloped wall.   
     
     
         19 . The brush gauge of  claim 15 , wherein the stepped barb is a first stepped barb and further comprising a second stepped barb extending into the aperture. 
     
     
         20 . The brush gauge of  claim 19 , wherein the first stepped barb is opposite the second stepped barb.
