Masking device for galvanized masking

Abstract

A masking device for masking an opening of a workpiece including a first end, a second end opposite the first end, a longitudinal axis that extends between the first end and the second end, and a cylindrical body extending between the first end and the second end. The cylindrical body has an outer periphery defining the circumferential outermost extent of the cylindrical body. The masking device further includes an aperture extending through the cylindrical body between the first end and the second end. The aperture has an inner periphery defining the circumferential innermost extent of the cylindrical body. The masking device further includes a tab extending away from the first end of cylindrical body along a direction parallel to the longitudinal axis.

1 . A masking device for masking an opening of a workpiece, the masking device comprising:
 a first end;   a second end opposite the first end;   a longitudinal axis that extends between the first end and the second end;   a cylindrical body extending between the first end and the second end, the cylindrical body having an outer periphery defining the circumferential outermost extent of the cylindrical body;   an aperture extending through the cylindrical body between the first end and the second end, the aperture having an inner periphery defining the circumferential innermost extent of the cylindrical body; and   a tab extending away from the first end of cylindrical body along a direction parallel to the longitudinal axis.   
     
     
         2 . The masking device of  claim 1 , wherein the cylindrical body defines a first wall thickness measured along a direction perpendicular to the longitudinal axis between the inner periphery and the outer periphery. 
     
     
         3 . The masking device of  claim 2 , wherein the tab defines a second wall thickness measured along a direction perpendicular to the longitudinal axis between the inner periphery and the outer periphery, wherein the first and second wall thicknesses are the same. 
     
     
         4 . The masking device of  claim 3 , wherein the first and second wall thicknesses are between 0.03125 inches and 0.125 inches. 
     
     
         5 . The masking device of  claim 3 , wherein the first and second wall thicknesses are approximately 0.0625 inches. 
     
     
         6 . The masking device of  claim 1 , wherein the outer periphery of the cylindrical body defines a first outer radius of curvature and the outer periphery of the tab defines a second outer radius of curvature, wherein the first and second outer radius of curvature are the same. 
     
     
         7 . The masking device of  claim 1 , wherein the inner periphery of the cylindrical body defines a first inner radius of curvature and the inner periphery of the tab defines a second inner radius of curvature, wherein the first and second inner radius of curvature are the same. 
     
     
         8 . The masking device of  claim 1 , wherein the aperture and the cylindrical body are co-axially with the longitudinal axis. 
     
     
         9 . The masking device of  claim 1 , wherein the cylindrical body is composed of a material that is heat resistant to at least 800 degrees Fahrenheit. 
     
     
         10 - 20 . (canceled) 
     
     
         21 . The masking device of  claim 9 , wherein the material is a flexible ceramic. 
     
     
         22 . The masking device of  claim 21 , wherein the flexible ceramic is a glass and resin matrix material. 
     
     
         23 . The masking device of  claim 22 , wherein the glass and resin matrix material is a fiber-reinforced elastomer.
