The outer plate is formed at its bore with at least one notch and the inner plate is formed adjacent its bore with at least two angularly offset and axially extending cutouts. A plug extending through the bores and rotatable therein about the axis has an outer head in the outer bore and accessible from outside the plates and an opposite inner end exposed inward past the inner plate. A locking dog extends radially from the plug in the space between the plates. An inner abutment washer is secured to the inner end of the plug and spaced axially inward of the inner plate and a retaining washer angularly nondisplaceable on the inner end of the plug has a bump engageable in the cutouts of the inner plate.

Abstract: An improvement in a door lock of the type having a rotatably mounted cam which has a detent which serves to displace a latching member and to engage the downstream abutment member of a pair of abutment members which are arranged upstream and downstream of the locking member with respect to the direction of rotation of the actuator cam. The abutment members are mounted on a lever arm which is connected to a locking bolt such that rotation of the actuator cam in one direction or the other will cause the detent to displace the locking member and thereafter engage the downstream abutment member to effect movement of the lever arm which in turn effects movement of the locking bolt between an open position and a closed position and to move the downstream abutment member clear of the path of the detent so as to permit the detent to gain access to the locking member when the direction of rotation of the actuator cam is reversed.

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.

Abstract: A key retaining multiple lock mechanism, suitable for parcel lockers and other structures and capable of being mounted on doors for such structures, has a first lock with a first key trapping tumbler mechanism. The first lock has a strike-engaging tongue and a spring loaded bolt cooperating with a second lock dead bolt structure. The dead bolt is operated by a second key to extend and retract the dead bolt. When extended, the dead bolt compresses the spring-loaded bolt when the mechanism is in a locked condition and acts as a stop when the mechanism is in the unlocked condition, preventing relocking of the structure without first retracting the dead bolt with the second key.

Abstract: A latch and lock mechanism having a pivoted latch and means for retracting the latch. A dead bolt is also provided. A rotatable bolt actuator has a pin and slot connection with the bolt to move the bolt to its extended, locking position. The bolt actuator also has means for simultaneously blocking retraction of the latch to provide in effect a double dead bolt lock.

Abstract: A self-locking lock assembly for a cabinet or locker door includes a rotary operating member (25) having a head (26) adapted to be operated from the exterior of the door, and an inner bolt (31) provided with a rib (36) inclined with respect to the axis of said operating member so that its cooperation with a flange (14) of a door opening (3) causes it to rotate while compressing a return spring (41) whenever the door is manually pushed. The lock assembly can advantageously be used in cabinets or lockers the doors of which must be opened only by safety personnel, but may be closed by maintenance personnel.

Abstract: Door-barring lock apparatus has a bar member rotatably mounted to the wall near the doorway. When in a transverse or generally horizontal position, this bar member projects into the doorway for engaging the inside of the door near the opposite margin from the hinges for advantageously, positively barring the door against opening inwardly. By manipulation of a handle located inside of the building near the bar member, a person inside of the building can de-couple the bar from a locking rod extending through the wall to the outside of the building. Such de-coupling enables the person inside of the building to rotate the bar into an upright position for freeing the door to allow the door to be opened, regardless of whether this rod is locked against rotation. A lock assembly accessible from the outside of the building normally serves to lock the rod against rotation for normally locking the bar member in its transverse door-barring position.

Abstract: A post office locker for use in the delivery of both letters and packages to tenants of a multiple tenant building or the like, wherein packages are stored in appropriately sized storage cabinets to which access may be gained by intended recipients by use of access keys placed by a mailman in the letter boxes of such recipients. Each cabinet is fitted with a latch mechanism permitting recipients to return doors of cabinets from which packages have been removed to locked condition in a manner providing for the "capture" of the access keys until removed by a mailman for subsequent use. Preferably, the doors are fitted with return mechanisms providing for locking of such doors automatically upon return thereof into closed condition.

Abstract: Deadbolt mechanism for holding a door in a closed position and including a deadbolt pivotally connected to the mechanism housing for movement into and out of that housing to adopt inoperative and operative positions respectively. A pin tumbler lock is used to operate the deadbolt and the lock barrel is rotated through 360.degree. during the change of deadbolt positions whereas the deadbolt swings through 90.degree. only. The drive between the lock barrel and deadbolt includes a pair of gear segments which engage during the 90.degree. travel of the deadbolt and are otherwise disengaged to permit the lock barrel to rotate free of the deadbolt. The drive also includes a pivoted arm which locates between side walls of the deadbolt and has a laterally extending pin slideably locating within a slot in each of the side walls. When the gear segments are engaged the arm is swung such that a camming action occurs between the pin and cooperating slots whereby the deadbolt is caused to move about its pivot.

Abstract: A fastening device for a door permits the actuation thereof by a handle, a locking element, or a key of normal kind. A bearing, fast to the wall of the door, can receive either a standard shaft, or a lock cylinder, or again a shaft having a head of particular shape, each of these three members being associated with a same operating handle and a same bolt.

Abstract: A lock mechanism particularly for doors having a narrow stile, wherein a unique arrangement of components provides greater security and facilitates manufacture and installation, as characterized by a heavy pivotally swingable main bolt connected at its inner end to one end of a rocker actuating lever, the end of the lever being provided with a unique escapement for the release and control of the movement of the rocker arm by an associated manually rotatable key-actuated cam extension, to move the main bolt between locked and unlocked positions. An important feature of the escapement resides in a unique arrangement of parts which is not critical as to the dimensions of the actuating cam extension, and which readily accommodate to actuating cams that may vary materially in their dimensions. The escapement also enables a better and more symmetrical resolution of the operating forces and the obtainment of maximum security.

The pivotal bolt extends outwardly from the housing when it is in a locking position. The key actuated means operates independently of the handle means and preferably rotates through an angle of at least 360.degree..
