Turning of the inside operating lever in either direction to open the door causes the turn button to return automatically to its unlocked position to prevent inadvertent locking of the door. Automatic return of the locking button is effected through the coaction of a spring-loaded pin on the inside lever with a pair of shoulders on the inner face of the turn button.

Abstract: A permutation lock assembly incorporated into a door knob and latch mechanism mountable in the standard openings in conventional swinging doors, using conventional door latch hardware. Rotation of an outer dial in a first direction causes rotation of an inner dial which is visible through a window until a number on the inner dial appears at the center of the window. Upon rotation of the outer dial in an opposite direction until a number thereon is aligned with a center mark, the door is unlocked and may be readily opened. When the proper combination is known, the combination may be changed, within a few seconds, from one combination to another. Also incorporated is a clutch device in the external knob that permits the knob to turn in either direction when the door is locked and excessive force is applied, thus preventing damage to the assembly.
