          Appeal No. 96-2299                                                          
          Application No. 08/072,753                                                  

               As for the argument that the details of the bearing                    
          construction recited in claims 15, 16 and 18 would not have                 
          been obvious to the artisan, we note that Witt describes the                
          pilot as “a ball-bearing pilot 29 which rolls against the                   
          unworked portion of the edge of the workpiece” (sentence                    
          bridging columns 2 and 3), and McKinney as a “ball bearing                  
          guide wheel 11 mounted . . . in a manner well known in the                  
          art” (column 3, lines 17-19).  It is our opinion that the one               
          of ordinary skill in the art would have recognized that ball                
          bearing guide wheels conventionally comprise one piece inner                
          and outer sleeves within which the ball bearings are mounted,               
          and would have found it obvious to mount the guide wheels such              
          that the inner sleeve is attached to the tool and the outer                 
          sleeve contacts the workpiece.                                              
               It therefore is our conclusion that the teachings of the               
          applied references establish a prima facie case of obviousness              
          with regard to the subject matter of the appealed claims, and               
          we therefore will sustain the rejection.                                    
               The decision of the examiner is affirmed.                              
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under                           

                                          8
