A cylindrical lock assembly includes an inside subassembly and an outside subassembly which are assembled with a door. Each subassembly includes a rose liner, a return spring cassette, a rose, a lever and a lever insert. The inside subassembly also includes a turn button and the outside subassembly includes a cylinder lock. The subassemblies are assembled onto respective sleeves of a chassis which facilitates the retraction of a latchbolt upon operation of either of the levers. Cassettes are mounted in the lock assembly by a pair of screws with one screw being inserted from one side of the door and the other screw being inserted from the other side of the door.

Ensemble de serrure cylindrique comprenant un sous-ensemble intérieur et un sous-ensemble extérieur qui sont installés dans une porte. Chaque sous-ensemble comporte une rondelle de rosette, un logement de ressort de rappel, une rosette, une béquille et une pièce insérée dans la béquille. Le sous-ensemble intérieur comprend aussi un bouton, et le sous-ensemble extérieur comprend une serrure à barillet. Les sous-ensembles sont installés dans les manchons correspondants d'un châssis, ce qui facilite la rentrée du pêne à ressort si une des deux béquilles est tournée. Les logements de ressort de rappel sont installés dans la serrure au moyen de deux vis, dont une est introduite à partir d'un côté de la porte, et l'autre est introduite à partir de l'autre côté de la porte.
