ABSTRACT:
For use with an electric meter having a flanged receptacle for holding the meter works and a flanged glass bowl for covering the meter works, a locking ring assembly consisting of a two-piece circular locking ring having two substantially semicircular sections for locking the glass bowl to the receptacle. One of the semicircular sections has a hinge fitting at one end and a radially extending leg at the other end. The other semicircular section has a mating hinge fitting at one end and a radially extending mating leg at the other end. The fittings are hingedly attached so that the two sections can be pivotally spread apart about the hinge axis of the fitting. This hinged connection permits the sections to be manually spread apart and easily applied over and around the flanges of the meter receptacle and the glass bowl. The radially extending mating legs have circular openings which are in axial alignment when the legs are drawn towards each other for clamping the glass bowl to the receptacle. When the legs are drawn towards each other, tension is exerted on the hinged connection. The tension on the hinged connection holds the ring sections together in an interlocked arrangement and hampers unauthorized access to the meter works.
