ABSTRACT:
A door stile lock has a rotary latch bar. The rotary latch bar contains a compression loaded anvil within its interior. The latch bar rotates about the lock cylinder housing. The housing is provided with retention ports for engaging the compression loaded anvil at selected positions to inhibit rotation of the latch bar when the anvil is so engaged. Interior of the cylinder housing is an actuator rotatable by the lock key. The actuator raises the anvil from the retention ports and drives the latch bar about the axis of the cylinder housing between nominal locked and unlocked positions of the latch bar. The compression loaded anvil engages the retention ports in the cylinder housing at both the nominal locked and unlocked positions. A lock body engages the cylinder housing in a non-rotating manner. The lock body is then compressively engaged within the door stile. The compression is provided by means of a screw driven U-shaped compression saddle having limited rotation about the driving screw fastener and the ability to translate along the axis of that screw fastener.
