摘要：A lock mechanism particularly for doors having a narrow stile, wherein a uniquearrangement of components provides greater security and facilitates manufacture andinstallation, as characterized by a heavy pivotally swingable main bolt connected at itsinner end to one end of a rocker actuating lever, the end of the lever being provided witha unique escapement for the release and control of the movement of the rocker arm byan associated manually rotatable key-actuated cam extension, to move the main boltbetween locked and unlocked positions. An important feature of the escapement residesin a unique arrangement of parts which is not critical as to the dimensions of the actuatingcam extension, and which readily accommodate to actuating cams that may varymaterially in their dimensions. The escapement also enables a better and more

symmetrical resolution of the operating forces and the obtainment of maximum security.The lock mechanism also includes an improved latching assembly operatively associatedwith the main bolt lock mechanism to provide both locking and latching operations,respectively, by means of a locking bolt and a latch member, and wherein the latchmember is spring-urged to a latched position and is independently operable to anunlatched position. The locking bolt is also arranged to be key-actuated in a normalmanner, the key being also further operable, in an unlocked position of the locking bolt,

to move the latch member to a retracted or unlatched position.
