              Application No. 10/079,706                                                                                  


                     The outer knob sleeve 30 has a threaded portion 44 on its exterior surface and a                     
              radially outwardly opening groove 46 formed therein which extends in an axial                               
              direction through the threaded portion.  The outer rose liner 34, best shown in Figures 2                   
              and 4, comprises a circular plate which has a generally cylindrical central opening 50                      
              somewhat larger than the diameter of the threaded portion 44, to receive the outer                          
              sleeve 30 therethrough.  An integral locking tab 52 projects radially into the opening 50                   
              and is received in the groove 46 to restrain the outer rose liner 42 against rotation                       
              relative to the outer sleeve 30.  Another integral tab 54 projects radially into the opening                
              50 in diametrically opposed relation to the locking tab 52.  The tabs 52 and 54                             
              respectively engage diametrically opposite portions of the outer sleeve 30 to maintain                      
              the outer rose liner 34 in generally coaxially alignment with the outer sleeve while the                    
              lock assembly 10 is installed on an associated door.  A coaxial annular bead 56 formed                      
              on the outer rose liner has a cylindrical portion 55 which is received within the bore 14                   
              and engages the wall thereof, as shown in Figure 1, to coaxially align the outer knob                       
              sleeve 30 with the bore 14.  A plurality of integral cantilever tabs 57 project in a radial                 
              direction from the rose liner 34.  Spurs 58 struck from or otherwise formed on the tabs                     
              57 cooperate with the outer face of the door 12 to prevent rotation of the outer rose                       
              liner 34 relative thereto when the lock assembly 10 is assembled with the door.  The                        
              outer rose liner 34 also has a circumaxial series axially outwardly opening recesses 59,                    
              59 defined by notches which open into the central opening 50.
