Wire Wheel Brush

Abstract

The improved wire wheel brush is of the type having a plurality of bristles extending radially from a hub to a periphery, the bristles defining a brush head. The improvement comprises: a ring of polymeric material through which the bristles extend from the hub, the ring having an outer perimeter smaller in circumference than the periphery of the wire wheel brush such that the bristles protrude therefrom.

1 . An improved wire wheel brush of the type having a plurality of bristles extending radially from a hub to a periphery, the bristles defining a brush head, the improvement comprising:
 a ring of polymeric material through which the bristles extend from the hub, the ring having an outer perimeter smaller in circumference than the periphery of the wire wheel brush such that the bristles protrude therefrom.   
     
     
         2 . The wire wheel brush according to  claim 1 , wherein the outer perimeter of the ring is about 1″ smaller in diameter than the periphery of the brush. 
     
     
         3 . The wire wheel brush according to  claim 1 , wherein the ring and the brush head each has a thickness measured in the direction of the rotation axis of the brush, the thickness of the ring being about 0.25″ greater than the thickness of the brush head. 
     
     
         4 . The wire wheel brush according to  claim 1 , wherein each bristle
 is about 0.015″ in diameter   is heated treated, brass-coated steel, the steel comprising alloying elements in about the following amounts:
