  • Patent number: 4977482
    Abstract: A watthour meter socket adapter includes a housing with electrical contacts which receive the terminals of a watthour meter and terminals which are insertable into the contacts of an electrical watthour meter socket. First and second seal connectors sealingly connect the adapter housing to the socket and a watthour meter to the adapter housing to control access to the socket, adapter and watthour meter. The interface connection includes an electrical connector mounted in an enclosure and connected to the contacts in the adapter housing to provide electrical power to an external interface. A third seal is connected and attached to the enclosure to control access to the electrical connections housed therein. In one embodiment, the enclosure is separate from and mounted on the adapter housing. In another embodiment, the enclosure is in the form of a sleeve mounted internally within the adapter housing with an open end allowing connection to an external electrical device.

  • Patent number: 4934747
    Abstract: A sealing ring for an electric meter socket has first and second spaced ends. A tongue with a plurality of linearly spaced apertures extends linearly outward from the first end of the sealing ring. A housing is mounted on the second end of the sealing ring and includes a passage for receiving the tongue therethrough. A threaded fastener is mounted in the housing and engages successive apertures in the tongue to advance and retract the tongue through the housing to connect and disconnect the sealing ring about the electric meter socket. At least one and preferably two seal tabs extend outward from the second end of the band and engage the apertures in the tongue. A seal member is emplaceable through the seal tabs to indicate a sealed mounting on the sealing ring on the electric meter socket.

  • Patent number: 4622753
    Abstract: A repair kit for an electric meter socket, which includes a set of jaw contacts mounted on a support plate, with means for mounting said plate in a desired spaced relation to the back of the meter box so that the blade contacts of the meter will be inserted into the jaw contacts for a suitable depth when assembled, and a template for temporarily mounting into the meter aperture in the meter box cover, said template having a series of guide holes for receiving a punch for marking the position for plate mounting holes in the back of the meter box, and means for orienting said template so that said holes will be in a position such as to allow the meter to be in a desired orientation after assembly.

  • Patent number: 4323294
    Abstract: A meter socket jumper assembly comprising a plastic disc having a diameter and an edge thickness substantially the same dimensions as a meter of the type designed for assembly in said socket. Said disc is provided with a series of integrally molded pockets shaped and dimensioned to receive a fastener such as a self tapping screw from the rear side to retain a jumper bar on said rear side. Said pockets are so designed that the self tapping screw assembled therein is not exposed on the front face of the disc. In a preferred embodiment of the invention the pockets protrude from the front of the disc and intersect stiffening ribs molded into the face of the cover, to strengthen the pocket walls against the expansive force of the fasteners inserted therein from the rear side.A plurality of pockets are provided, suitably spaced to allow the assembly of jumpers in several different predetermined positions to accomodate different types of meter sockets.

  • Patent number: 4311354
    Abstract: A meter disconnect adaptor for assembly into a residential electric meter socket. The adaptor has a base with a peripheral configuration which allows it to be used with either a ringless type of meter box, or in a ring type of mounting, and has blade simulating members extending from one side of the base and resilient fingers extending from the other side of the base for receiving contact blades of the electric meter. In one embodiment of the invention the adaptor has a group of resilient fingers arranged to allow assembly of the meter therein in any one of a number of orientations.
