Abstract: An improved night depository for depositing an article through the wall of a building into a safe. The depository includes a casing that is mounted within an opening in the wall and a receptacle pivotally mounted about a horizontal axis within the casing. The receptacle includes a door, two vertical sides, and a floor. One end of a movable wall is pivotably mounted to the outboard end of the receptacle floor. When the receptacle is rotated about the horizontal axis to open the door the unattached end of the movable wall pivots towards the receptacle floor. The receptacle sides are separated from the edges of the movable wall by a clearance that is sufficiently small enough to impede the flow of air about the edges of the movable wall as the movable wall pivots. The air underneath the movable wall escapes through a gap between the unattached end of the movable wall and the door at a rate which cushions the impact of the unattached end against the receptacle floor.

Abstract: An improved vault door having a daylock and a relock mechanism is disclosed. The door is selectively locked and unlocked within a frame of the vault by operating a pair of combination locks mounted to the door front to slide a lock bar mounted to the rear of the door. The daylock mechanism includes a spring biased member which engages a cavity in a daylock extension attached to the lock. This engagement holds the lock bar in the unlocked position so the door may be swung within the frame without the lock bar impacting the frame. A keylock mounted in the front of the door may be turned to withdraw the member from the cavity so the lock bar can be slid to secure the door in the frame. The relock mechanism includes a pivotably mounted bar held in a horizontal position by a pin mounted to an attack plate that is displaceably mounted to a mounting plate on the rear of the door.

Abstract: An improved modular type safety deposit box system. In preferred form, each module is comprised of the same basic casing structure, and an initially separate door frame structure, these two components then being assembled into a completed module after pre-assembly of each component. Each module's casing may be subdivided into more than one compartment by use of a plurality of standardized horizontal dividers and, if desired, standardized vertical dividers, the dividers being arranged as desired in operative engagement with the casing through a slot and tab structure. Each module's door frame is comprised of a hoop-shaped frame adapted to be subdivided into a plurality of access ports corresponding to the same number of compartments provided in the basic casing. The doors for each access port of the frame may be installed to hinge from one side of the frame if no vertical dividers are used in the casing, or from a center hinge post fixed in the frame if vertical dividers are used in the casing.
