Abstract: A lock for meter boxes and similar enclosures includes an outer case with a central bore mounted on an electric meter box. Inside the bore are two extrusions of unequal length spaced 90 degrees apart. A sleeve having a deep bore is held in the case by a screw, and a spring assembly transmits motion from the screw to the sleeve. The sleeve includes a flange at its end with an arcuate cutout portion which spans both extrusions. The sleeve further includes several internal grooves for retaining a barrel type lock which prevents access to the screw. A heavy cover plate is welded to the top of the sleeve so that it overlays and retains the door of the meter box. To unlock the meter box lock, the barrel lock is removed to allow access to the screw. As the screw is unscrewed, the sleeve moves with the screw until the flange on the sleeve clears the shorter extrusion. The sleeve then rotates with the screw until the flange engages the longer extrusion.

Abstract: A locking device for a storage container such as a tool box in which a hinged lid includes a pair of spaced detents depending to a latching configuration at their distal ends. Cooperating with the detents is a tubular conduit slidably displaceable and including slots in an upper surface in which to receive and secure the distal ends of the detents. A padlock for unlocking the box is received within a recess of the tool box providing exterior exposure to only the key end of the lock. Opening the padlock causes the lock body to eject partially outward of the tool box while forming a gap between the latching end of the lock shackle and the lock body. Secured to the conduit in the plane of the gap is a manually displaceable wing which when the lock is opened can be displaced into the gap to in turn displace the conduit and enable release of the detents.

Abstract: A self-adjusting lock has a keeper stud with a base that is mounted in a recess in a keeper assembly so that it can slide in four directions. As the bevelled keeper stud is pressed into an opening in a latch assembly, the stud self-adjusts in the necessary direction to achieve alignment. A spring pressing the base against a surface causes the base, and so the keeper stud, to be frictionally held in its new position. The keeper stud has a series of spaced ratchet teeth, axially separated from one another, any of which can interengage with the latch mechanism. Thus, the lock is adjusted in this direction each time the lock is closed, resulting in a lock self-adjustable in six directions.
