A cylindrical lockset (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (208). Each subassembly (22, 24) includes a liner (26, 36), a rose (28, 38) and a lever (30, 40). A chassis assembly (58) includes a pair of sleeves (66, 68), a pair of spri
A cylindrical lockset (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (208). Each subassembly (22, 24) includes a liner (26, 36), a rose (28, 38) and a lever (30, 40). A chassis assembly (58) includes a pair of sleeves (66, 68), a pair of spring plates (146, 192), a pair of torsion springs (166, 194), a cap (172), a case (182) and a retractor (70) which is coupled to the latchbolt (46). Upon operation of either of the levers (30, 40) from a non-operated or home position, the latchbolt (46) is retracted and the associated one of the springs (166, 194) is tensioned so that, upon release of the levers, the springs return the levers to the home position.

A cylindrical lockset comprising a latchbolt, a mechanism for moving the latchbolt between a latched position and an unlatched position, an axially aligned pair of rotatable sleeves operatively associated with said mechanism, a housing for said mechanism including a cylindrical shell having closed opposed ends each having an opening therein for receiving one of said rotatable sleeves, a pair of coil torsion springs inside said shell, one of said coil torsion springs received by each of said rotatable sleeves, and said received coil torsion springs located adjacent said closed ends, a pair of ring shaped plates inside said shell, one of said ring shaped plates received by each of said rotatable sleeves, said received ring shaped plates located adjacent said coil torsion springs so that each coil torsion spring is captured between one of said closed ends and one of said ring shaped plates, each rotatable sleeve and said ring shaped plate received thereon including cooperating key and keyway means for establishing a rotational connection therebetween so that rotation of said rotatable sleeve will rotate said rotationally connected ring shaped plate, and each ring shaped plate and adjacent closed end including cooperating tab means for subjecting said coil torsion springs to an increasing stress as said ring shaped plates are rotated.
