Brush block with diaphragm tuning channels

Abstract

The current invention is a brush block (a bristle carrier) with diaphragm tuning channels. The incorporation of a diaphragm within a brush is useful in some circumstances. Diaphragm tuning channels which generally encircle the long axis of a brush block, as well as diaphragm tuning channels which generally parallel the long axis of a brush block, can both be used to control or tune the forces exerted by the diaphragm, while the implement is in use.

1 . A brush block for a hand-held implement including a diaphragm tuning channel.  
   
   
       2 . An implement as in  claim 1  which is polypropylene.  
   
   
       3 . An implement as in  claim 1  which is injection molded.  
   
   
       4 . An implement as in  claim 1  which is greater than twenty centimeters long and less than sixty centimeters long.  
   
   
       5 . An implement as in  claim 1  which is substantially circular in cross-section.  
   
   
       6 . An implement as in  claim 1  which is less than ten centimeters in diameter.  
   
   
       7 . A method of building a hand-held implement, comprising the steps: 
 (a) mounting a diaphragm on a brush block including a diaphragm tuning channel; and    (b) filling the brush.    
   
   
       8 . A method of building a hand-held implement, comprising the steps: 
 (a) filling a brush; and    (b) mounting a diaphragm on the brush block which includes a diaphragm tuning channel.
