Abstract
Abstract A cylindrical lock assembly (20) includes an inside subassembly (22) and an outside subassemlby (24) which are assembled with a door (326). Each subassembly (22,24) includes a rose liner (26,38), a return spring cassette (28,40), a rose (30,42), a lever (32,46) and a lever insert (34,48). The inside subassembly (22) also includes a turn button (36) and the outside subassembly (24) includes a cylinder lock (44). A pair of sleeves (168,170) extend from opposite sides of the chassis (50) and are each formed with three slots which facilitate mounting of the levers (32,46) and the cylinder lock (44) thereon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
A cylindrical lock assembly, which comprises: a latchbolt; a mechanism for moving the latchbolt between a latched position and an unlatched position; at least one sleeve extending from one side of the mechanism and engageable therewith for operating the mechanism upon rotation of the sleeve; an operator mounted on the sleeve for facilitating selective rotation of the sleeve; a lock having a rib formed therewith; a first slot formed in one end of the sleeve in a first orientation relative to the axis of the sleeve; a second slot formed in the one end of the sleeve in a second orientation relative to the axis of the sleeve and spaced from the first slot by a first prescribed radial distance; and a third slot formed in the one end of the sleeve in a third orientation relative to the axis of the sleeve and spaced from the first slot by a second prescribed radial distance different from the first prescribed radial difference.
Claim 2
Dependent Claim
162 words
A cylindrical lock assembly, which comprises: a latchbolt; a mechanism for moving the latchbolt between a latched position and an unlatched position; at least one sleeve extending from one side of the mechanism and engageable therewith for operating the mechanism upon rotation of the sleeve; an operator mounted on the sleeve for facilitating selective rotation of the sleeve; a lock having a rib formed therewith; a first slot formed in one end of the sleeve in a first orientation relative to the axis of the sleeve; a second slot formed in the one end of the sleeve in a second orientation relative to the axis of the sleeve and spaced from the first slot by a first prescribed radial distance; and a third slot formed in the one end of the sleeve in a third orientation relative to the axis of the sleeve and spaced from the first slot by a second prescribed radial distance different from the first prescribed radial difference.
Claim 3
Dependent Claim
29 words
A cylindrical lock assembly as set forth in claim 1, wherein the slots are formed from a first end of the sleeve and extend toward a second end thereof.
Claim 4
Dependent Claim
39 words
A cylindrical lock assembly as set forth in claim 2, wherein the second slot is greater in length from the first end of the sleeve than the first and third slots to receive a drive bump of the operator.
Claim 5
Dependent Claim
36 words
A cylindrical lock assembly as set forth in claim 2 which further comprises a camming element formed integrally with the sleeve at the second end thereof for engaging the mechanism to facilitate movement of the latchbolt.
Claim 6
Dependent Claim
45 words
A cylindrical lock assembly as set forth in claim 2 which further comprises: a second sleeve extending from a side of the mechanism opposite the one side and formed with first, second and third slots in the same manner as the at least one sleeve.
Claim 7
Dependent Claim
157 words
A cylindrical lock assembly, which comprises: a latchbolt; a mechanism for moving the latchbolt between a latched position and an unlatched position; a pair of sleeves extending from opposite sides of the mechanism and engageable therewith for operating the mechanism upon rotation of the sleeve; an operator mounted on each of the sleeves for facilitating selective rotation of the sleeves; a lock having a rib formed therewith; a first slot formed in a first end of each of the sleeves in a first orientation relative to the axis of the sleeve; a second slot formed in the first end of each of the sleeves in a second orientation relative to the axis of the sleeve and spaced from the first slot by a prescribed radial distance; and a third slot formed in the first end of each of the sleeves in a third orientation relative to the axis of the sleeve and diametrically opposite the first slot.
Claim 8
Dependent Claim
157 words
A cylindrical lock assembly, which comprises: a latchbolt; a mechanism for moving the latchbolt between a latched position and an unlatched position; a pair of sleeves extending from opposite sides of the mechanism and engageable therewith for operating the mechanism upon rotation of the sleeve; an operator mounted on each of the sleeves for facilitating selective rotation of the sleeves; a lock having a rib formed therewith; a first slot formed in a first end of each of the sleeves in a first orientation relative to the axis of the sleeve; a second slot formed in the first end of each of the sleeves in a second orientation relative to the axis of the sleeve and spaced from the first slot by a prescribed radial distance; and a third slot formed in the first end of each of the sleeves in a third orientation relative to the axis of the sleeve and diametrically opposite the first slot.
Claim 9
Dependent Claim
35 words
A cylindrical lock assembly as set form in claim 6, which further comprises: a camming element formed integrally with a second end of each of the sleeves adjacent the mechanism and engageable with the mechanism.
