Abstract

Sacrificial anodes and line cutters which are formed into a single unit.

1 . A sacrificial anode device comprising:
 An article formed of chemically-active metal having a cutter blade formed therein.   
     
     
         2 . The device of  claim 1  wherein:
 said cutter blade is formed of strong, rigid non-metallic material. 
 
     
     
         3 . The device of  claim 1  wherein:
 said device is annular. 
 
     
     
         4 . The device of  claim 3  wherein:
 said device comprises upper and lower semi-circular halves. 
 
     
     
         5 . The device of  claim 4  wherein:
 said halves are formed with bolt holes for securing said halves together. 
 
     
     
         6 . The device of  claim 5  wherein:
 said bolt holes are both on the same side of said cutter blade. 
 
     
     
         7 . The device of  claim 5  wherein:
 one of said bolt holes is on one side of said cutter blade and the other of said bolt holes is on the opposite side of said cutter blade. 
 
     
     
         8 . The device of  claim 1  wherein:
 said cutter blade is formed of carbide. 
 
     
     
         9 . The device of  claim 2  wherein:
 said cutter blade has teeth which project beyond the periphery of said article. 
 
     
     
         10 . The device of  claim 1  wherein:
 said cutter blade is molded into said article. 
 
     
     
         11 . The device of  claim 1  wherein:
 said cutter blade is screwed onto said article.
