  • Patent number: 6032989
    Abstract: A locking ring includes two semi-annular ring portions with a U-shaped cross section. The locking ring serves to retain an electric meter in its meter socket in a manner which is well known. Both ends of each ring portion terminate in housings, each housing having an axial lock receiving aperture therethrough. When the ring halves are brought together to form a complete circle, the clockwise-most and counter-clockwise-most housings slide over each other until their lock receiving apertures are in axial alignment. A barrel lock can then be inserted into each of the two sets of aligned apertures, to secure the locking ring against opening. When a barrel lock is removed from either set of apertures, the ring can be opened at that location and removed from the meter.

  • Patent number: 5890439
    Abstract: An improved safe deposit assembly including an outer housing, a removable inner container, and one or more lock devices which may be in signal communication with a time-delay device for securing valuables within. To unlock and remove the inner container from the outer housing, a separate cover is slid in to a slot on the outer housing. The cover locks a lock before releasing a latch, and neither the lock or latch are accessible until the container is removed from the housing. But a first lock must be unlocked before the cover may be slid in. The first lock may be in signal communication with a time delay to device to thwart robbery attempts. As the cover is slid in it first becomes trapped by a spring lock on the inner container and then it releases a second spring bolt lock that both seals the inner container and releases it from the outer housing. The sealed inner container may only be opened by unlocking the lock device.

    Abstract: A multi locking hasp apparatus using two padlocks with lock keeper loops, two pivotally mounted jaws and a common back plate joined to the jaws at its pivotal mount. The free upper ends of each jaw engage holes in a hasp to lock the two members together as long as both padlocks remain locked in place. Should one of the two padlocks be unlocked and its keep loop removed from the jaw and back plate, the other padlock can be removed from the hasp's hole without unlocking it. This permits a series of secure areas or compartments to have a common lock with a common key or combinational lock while others may also unlock the other locks with individual keys or combinations.

    Abstract: A guard plate is used to protect a door from forced entry where the door is used in conjunction with a doorjamb. The door has a lock cylinder in it, and this cylinder is operatively interconnected with a reciprocal bolt for entering an opening in the doorjamb in a conventional manner. The guard plate has first and second interconnected sections. An opening is provided through the first section for accommodating the portion of the lock cylinder which normally is exposed on the surface of the door in which the cylinder is mounted. The first section of the plate then is secured to the door, with the lock cylinder aligned with the opening in the first section. The second section also has an opening through it, and the two sections are interconnected together with a bridge. The bridge causes the second section of the plate to overlie the doorjamb when the door is closed, and the bridge itself overlies the space between the door and the doorjamb when the door is in its closed position.

An additional member is mounted on the frame for slidable movements generally parallel to the bolt. At least two locking means are incorporated into the locking mechanism, the first of which releasably connects the bolt to the member, and the second of which releasably positions the member with respect to the frame. With the first locking means engaged, the bolt is movable together with the member. With both the first and second locking means engaged, the bolt is locked in the extended position. A securing means engagable with the first locking means prevents release of the first locking means. The locking mechanism is particularly adapted for use on storage compartments wherein a renter of the compartment will gain access by way of the first locking means and the owner will gain access by way of the second locking means.

  • Patent number: 4113291
    Abstract: A combination door handle and security locking system in which the conventional door latch is actuated by turning the five-sided head of an operating shaft with a special socket wrench. A hinge plate having a slot for a padlock bail and a flat index tab on its inner surface is rotated to cover the operating shaft head. The tab must fit against one side of the operating shaft head to allow the hinge plate to be fully closed so that a padlock can be inserted in the bail. The latching mechanism is designed so that this tab will fit against one side of the operating head when the door is fully latched, to thus prevent rotation of the latching mechanism. The free end of the hinge plate has an offset portion which serves both as a sleet hood for the padlock and as a handle for opening the door.

  • Patent number: 4067212
    Abstract: A two dead bolt door lock is disclosed wherein the bolts are transversely disposed and wherein the bolts are disposed one behind the other in the locked position so as to provide a secure locking mode. When door mounted, and in the locked position, a vertical bolt is disposed on the inside of the door adjacent the jamb and a horizontal bolt is mounted in the jamb. Attempts to jimmy the horizontal bolt in its line of least resistance are frustrated by the presence of the vertically locked bolt acting against the jimmying force. The locks are both operated by a single key actuated cylinder and/or hand knob through a common connection rod with coordinated cam actions. In another embodiment, keys may be employed on both the inside and the outside of the door.

  • Patent number: 3988031
    Abstract: This invention relates to a multiple padlocking device commonly used in conjunction with gates for the entrance to a particular piece of property. A vertical rotatable plate is carried on a stationary horizontal axis in the same plane as the fence and gate when the gate is closed. A series of holes are located in the rotatable plate with individual bars being pivotally attached to the plate to cover each respective hole. Locking holes are contained in both the rotatable plate and each pivotable bar contained thereon to lock the bar into a position covering each of the respective holes. A horizontally slidable locking bar which is in the same plane as the gate, slidably extends through a gatepost with one end thereof extending into a hole in a fencepost.
