Nt Falcon Lock

Eugene S McCaa

A driver element in this lock has two outer surface sections. The first of the sections has a first geometrical cross-sectional configuration which engages an outer lever spindle in both the locked and unlocked condition. In the unlocked condition the first section also engages an outer driver spindle which rotates with the outer lever handle and outer lever spindle and engages the latch retraction structure for retraction of the latch. In the locked position, a push button on the inner handle pushes the driver such that a second section of the outer surface of the driver is aligned with the outer drive spindle and the second section is free of driving engagement with the outer driver spindle such that operation of the latch is prevented when the outer lever handle is rotated.
