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 securing device for a cover of a utility wire pull box including an inverted Y-shaped member having diverging legs which are engagable at their lower spaced ends beneath the lower margins of opposing walls of the pull box and at its upper main upright portion through a slot formed through the in-place cover. A lock arrangement such as a padlock may then be secured through a hole in the upright portion which is exposed above the slot in the cover.

Abstract: A key lock snap assembly for securing fabric covers to a supporting structure has a base member to be mounted on a supporting structure and having a post with a collar intermediate its length. A key lock snap engaged on the base member has a body with a flange adapted to engage with a fabric cover and an upstanding generally cylindrical barrel providing a top wall with a key-receiving aperture therein and a downwardly opening generally cylindrical cavity. Seated in the cavity are a key code having a key passage, a locking element resiliently deflectable about the collar of the post and engageable with the post, and a rotatable lock in the barrel which will engage the locking element in its position engaging the post below the collar, and this precludes deflection of the locking element about the collar. A key is insertable into the aperture of the top wall of the body and through the aperture of code element into the lock to effect its rotation.

Abstract: A doorbell block (A) is disclosed which includes a cover (18) and a pair of movable sidewalls (26, 28) which are biased towards each other to grippingly engage a doorbell housing (14) so that a face plate (20) of the cover prevents actuation of the door bell button (16) and unwanted rings. Tab openings (E) allow the user to spread the sidewalls apart for installation and removal. A biasing spring (C) urges the sidewalls together to grippingly engage the doorbell housing to retain the cover in place.

Abstract: An arrangement to releasably secure each of the two doors of a utility carrier box mounted transversely behind the cab of a pick-up vehicle and on the side walls of the pick-up, the arrangement comprising staples secured to the end walls of the box below the end flanges of the doors when the doors are in closed position, and a steep strap extending from below one staple, over the top of the closed box and down to a point beyond the other staple, and in conformity with the surface of the closed box over which the strap means extends, each end of the strap being slotted to enable the link of the staple beyond which it extends to be passed through the slot and to receive the link of a padlock which is locked.

Abstract: A device for locking a rectangular electric meter box having an openable front cover. The device has an L-shaped lock housing which includes a first leg fixed to the front cover of the box and a second leg which is detachably fastened to the side wall of the box when the front cover is closed. A barrel lock is inserted into the second leg of the lock housing to block unauthorized removal of the detachable fastener from the side wall of the meter box.

Abstract: A locking assembly for electrical enclosures to prevent unauthorized tampering with internal power connections. The locking assembly comprises an adjustable bracket which is secured to the walls of the enclosure by bolts; a cover which covers the open front and a substantial part of the sides of the enclosure and which is secured by a bolt to the adjustable bracket, a locking shield which overlies and prevents removal of the bolt which attaches the cover to the adjustable bracket, and a removable lock bolt which secures the shield to the cover.

Abstract: Force-resistant locking devices for electric meter boxes with hinged cove or the like, comprise a stud member mounted to a wall of the box and a flange member received on the stud member, the flange member including a flange overlying a marginal portion of the cover to keep it closed. The flange and stud members together define an opening receiving and fully enclosing a utility lock for securing the flange and stud members together. In one embodiment, the flange member is an angle iron with rectangular metal stock welded to one leg, and the stud is cylindrical and received in an opening through the flange member. The lock-receiving opening intersects the stud-receiving opening and the shear strength of the utility lock holds the locking device together. In another embodiment, the flange member is a section of channel iron and receives a rectangular stud, the lock-receiving opening deployed to utilize the shear strength of the lock.

Abstract: A highly tamper-resistant lock for attachment to an electric meter box, as a supplement to other locking means, if any, or a replacement therefor, the lock having one part secured to the box and a separable part adapted to be locked in engagement with the first part and in a position to prevent separation of the parts to project in front of the meter box cover to prevent opening thereof. The part secured to the box includes a reinforcement member having at least one wing piece which engages a portion of the separable part in the locked position to prevent tilting of the separable part by prying. The lock for the separable part is shown as a plunger type lock, to be inserted in a deep tubular chamber.

Abstract: The present device is a means for preventing unauthorized access to an electric meter box, and comprises a clamp holding the box lid shut, the clamp being locked in place overhanging the lid by a bolt through a bracket fixed on the box wall and a bolt type lock passed through registering holes in the clamp and bracket. All parts except the overhanging and adjacent portion of the clamp and a small portion of the lock are shielded from tampering by an enclosing yoke locked in place by the lock.
