Claim 13

A locking device adapted for combination with electric meter boxes or the like of the type having a bottom, a back wall, side walls, and a front wall and a cover hingedly or otherwise attached to the back wall and pivotal to a closed position, the locking device comprising: (A) a stud member mounted to one of the walls other than the back wall of the electric meter box, the stud member comprising a cylindrical stud extending perpendicularly outwardly from the wall to which it is mounted, the cylindrical stud defining a portion of a lock-receiving opening disposed generally perpendicular to the closed cover of the electric metor box; and (B) a flange member comprising an L-shaped angle iron one leg thereof comprising a flange overlaying a marginal portion of the cover and a rectangular portion of metal stock welded to the other leg thereof to form a flange body, the flange body defining a stud-receiving opening generally parallel to the flange and passing through the depending leg of the angle iron and the metal stock welded thereto, the metal stock of the flange body further defining the remaining portion of the lock-receiving opening disposed generally perpendicular to the closed cover of the electric meter box the portions of the lock-receiving openings defined by the stud and the flange member being aligned to form the complete lock-receiving opening when the flange member is received on the stud member, the lock-receiving opening accommodating a utility lock of the type having a head, a shank and locking balls expansible outwardly from the shank to engage a shoulder of the lock-receiving opening and thereby retain the utility lock therein, the lock being fully enclosed and protected by the locking device and retaining the flange and stud members of the locking device together by its shear strength.

Claim 14
