The outer housing includes a notch and an elongate arcuate slot formed in the inner surface of the outer housing adjacent a through aperture and across from one another. A lock control lug is moveably coupled with the outside drive assembly and is selectively engageable with the notch or the arcuate slot of the outer housing. An outer lever is placed in a non-clutching configuration when the lock control lug is engaged with the notch and in a clutching configuration when the lock control lug is engaged with the arcuate slot. ## Claims ### Claim 1 A lock assembly comprising: an outer housing positionable adjacent an outer surface of a door; an aperture formed through the outer housing; a notch formed in an inner surface of the outer housing adjacent the aperture; an arcuate slot formed in the inner surface of the outer housing adjacent the aperture and across from the notch; an outside drive assembly coupled to the outer housing with a portion thereof positioned through the aperture; a lock control lug moveably coupled with the outside drive assembly, the lock control lug selectively engageable with the notch or the arcuate slot of the outer housing; an outer lever connected to the outside drive assembly; wherein the lever is in a non-clutching configuration when the lock control lug is engaged with the notch and the lever is in a clutching configuration when the lock control lug is engaged with the arcuate slot. ### Claim 2 (depends on 1) The lock assembly of claim 1, wherein the notch and the arcuate slot are positioned approximately 180 degrees from another about the aperture. ### Claim 3 (depends on 1) The lock assembly of claim 1, wherein the outside drive assembly is converted between the clutching and the non-clutching configurations when the outer housing is rotated approximately 180 degrees relative to the outside drive assembly. ### Claim 4 (depends on 1) The lock assembly of claim 1, wherein a width of the notch is approximately the same as a width of the lock control lug. ### Claim 5 (depends on 1) The lock assembly of claim 1, wherein a width of the arcuate slot is wider than the lock control lug and defines an angle of rotation of the outer lever in a locked state. ### Claim 6 (depends on 1) The lock assembly of claim 1 further comprising a visual indicator formed on the inner surface of the outer housing. ### Claim 7 (depends on 6) The lock assembly of claim 6, wherein the visual indicator corresponds to one of either the clutching or the non-clutching configuration. ### Claim 8 (depends on 7) The lock assembly of claim 7, wherein the outside drive assembly includes a flange with a port formed therethrough. ### Claim 9 (depends on 8) The lock assembly of claim 8, wherein the visual indicator is aligned with the port when the outside drive assembly is assembled with the outer housing. ### Claim 10 (depends on 8) The lock assembly of claim 8, wherein the visual indicator can be viewed through the port of the outside drive assembly. ### Claim 11 (depends on 6) The lock assembly of claim 6, wherein the visual indicator includes one or more of an alpha numeric character, a symbol, and/or an open pocket. ### Claim 12 (depends on 1) The lock assembly of claim 1, wherein the outside drive assembly is removably connected to the outer housing via fastening means. ### Claim 13 A cylindrical lock assembly comprising: an outer spring cage housing having an outer wall and an inner well; a notch formed in a first portion of the inner wall; an elongate arcuate slot formed in a second portion of the inner wall, the elongate arcuate slot being positioned approximately 180 degrees from the notch; an outside drive assembly coupled to the outer spring cage housing; a lock control lug operably coupled with the outside drive assembly, the lock control lug being selectively engageable with the notch or the arcuate slot of the outer spring cage housing; and wherein the outside drive assembly defines a clutching configuration when the lock control lug is engaged with the arcuate slot and a non-clutching configuration when the lock control lug is engaged with the notch. ### Claim 14 (depends on 13) The cylindrical lock assembly of claim 13 further comprising, a visual indicator formed on the inner wall of the spring cage housing constructed to indicate whether the lock assembly is in a clutching or a non-clutching configuration. ### Claim 15 (depends on 14) The cylindrical lock assembly of claim 14 further comprising a flange extending from the outside drive assembly and connectable to the outer spring cage housing. ### Claim 16 (depends on 15) The cylindrical lock assembly of claim 15, wherein the flange of the outside drive assembly includes a port configured to align with the visual indicator on the outer spring cage housing. ### Claim 17 (depends on 14) The cylindrical lock assembly of claim 14, wherein the visual indicator includes at least one of an alpha numeric character, a symbol, and/or an open pocket. ### Claim 18 (depends on 15) The cylindrical lock assembly of claim 15 further comprising an outside lever spindle extending from the outside drive assembly. ### Claim 19 (depends on 18) The cylindrical lock assembly of claim 18 further comprising a lever handle connected to the outside lever spindle. ### Claim 20 (depends on 19) The cylindrical lock assembly of claim 19, wherein the lever pivots relative to the outer spring cage housing in the clutching configuration and is fixed relative to the outer spring cage housing in the non-clutching configuration in a locked state. ### Claim 21 A method for converting a lock assembly between a clutching and a non-clutching orientation comprising: forming a notch in an inner wall of an outer spring cage housing; forming an elongate arcuate slot in the inner wall of the spring cage housing, the notch and the elongate slot positioned on opposing sides of a through aperture formed in the spring cage housing; assembling an outside drive assembly with the outer spring cage housing; inserting a lock control lug operably coupled with the outside drive assembly into one of the notch and the arcuate slot; wherein engagement of the lock control lug with the notch defines an non-clutching orientation and engagement of the lock control lug with the arcuate slot defines a clutching orientation of the outside drive assembly; and rotating the outer spring cage housing approximately 180 degrees relative to the outside drive assembly such that the lock control lug engages with the other of the notch and the arcuate slot to convert the orientation of the lock assembly. ### Claim 22 (depends on 21) The method of claim 21 further comprising placing a visual indicator on the outer spring cage housing to display the orientation of the outside drive assembly. ### Claim 23 (depends on 22) The method of claim 22 further comprising, forming a port in a portion of the outside drive assembly that aligns with the visual indicator of the outer spring cage housing.
