Electrical service providers generally deliver electricity to their customers via power lines buried underground or distributed along poles or towers overhead. The provider's power lines are usually distributed from a power generation station to various sets of customer lines, so that customers can then use the power to satisfy their various electrical needs. To measure delivered power so that customers can be billed in proportion to their usage, service providers typically terminate their power lines at a customer's home or business facility through a metered socket box, various designs for which are well known.
For example, one known watthour meter socket consists of a meter box having two sets of electrical connections, with a provider's transmission lines being connected to one set of connections, and the customer's service lines to the other set. To establish a circuit and measure the amount of electricity a customer uses, the socket box is configured to accept a watthour meter, or another electricity usage measurement device, which, when plugged into the socket, permits transmission of electricity from the provider to the customer and allows the amount of transmitted electricity to be measured in watthours, so that the provider can charge the customer for power usage at an appropriate rate.
Various designs and uses for watthour meters are also well known, and all such designs and uses are incorporated into the teachings of the present invention. The present invention is also applicable in situations where the customer's electrical service lines are routed from the socket box to a breaker box, so that electricity can be distributed to various other service locations using additional sets of power lines or wires.
There are several known types of socket meter boxes, each being distinguished by the method in which the meter is secured in place once it has been plugged into the socket. For example, there is a ringless type meter box, which typically includes a meter box, an installed meter, and a box cover. A flange is formed around a meter head passage space disposed in a central portion of the box cover. A complementary flange is disposed on the meter base, so that the complementary flange sections join together when the meter head passage space is placed over and around the meter head. The meter box cover is then secured using a security device, for example, a small latch assembly or the like, disposed on the box cover, which functions in structural cooperation with a complementary latch-receiving member disposed on the meter box, thereby ensuring that the meter cannot be easily removed without first removing the cover after installation is complete.
As seen in
The box cover also prevents unauthorized persons from tampering with an installed meter. For example, some customers have attempted to bypass the meter, so that unmeasured electricity could be used free of charge. Also, service providers are sometimes forced to disconnect service to customers, for example, due to non-payment of monthly bills. In this event, the box cover keeps a customer from entering the socket box and reconnecting electrical service. However, in instances where a small latch assembly on the box fails to provide sufficient security for the meter and socket box, a sturdier, more tamper resistant solution is required.

Once terminus portions 61, 62 have been drawn together, a locking mechanism 70 is attached so that terminus portions 61, 62 are securely held. A fastener 75 is aligned with a captured nut 80, and then rotatably threaded into a receiving portion of captured nut 80. Installation of fastener 75 is usually completed using a screwdriver or another hand tool. As fastener 75 is progressively threaded into captured nut 80, terminus portions 61 and 62 are drawn together until the band is tightly wrapped around a circumference of the meter and box flange combination, thereby securing the meter in place within the box.
There are other known sealing ring housing and fastener configurations. For example, a box-sealing ring is disclosed in U.S. Pat. No. 5,851,038, in which a pair of sealing ring housings is disposed on opposite ends of an annular band. Bendable mounting tabs are extended from each of the ring housings into slots disposed in the band. A threaded fastener extends through a first threaded aperture disposed in one housing, and then through a second threaded aperture disposed in an opposite housing. An enlarged fastener head enables the installer to hand thread the fastener through each of the apertures during initial phases of installation. Fully threaded installation of the fastener is effected by inserting a screwdriver into receiving slots formed in each end of the fasteners and then rotating the screwdriver.
An axial slot cut in one end of the fastener is aligned with an aperture provided in the walls of the opposite housing member to permit attachment of a security device. Known methods of attaching the housings to the band include riveting the housings onto the ring, combining rivets with tabs to affix the housings to the band, and welding the housing to the ring.
In view of the foregoing, it is apparent there exists a strong need for an inexpensive and effective means by which a watthour meter can be reliably secured to a socket box cover. There is also a need for a meter box cover locking device that is simple in design, requires a reduced number of parts, and permits an installer to quickly, safely and effectively install the device in some cases without the use of tools.
According to one example embodiment, an apparatus for securing a watthour meter to a meter box cover is provided comprising: an annular band, wherein a body portion of said annular band is divided to further comprise a first band portion and a second band portion; a first tab member disposed on said first band portion, wherein a first aperture region is formed through a body portion of said first tab member; a ring fastener having a first end and a second end; and a ring fastener support member for supporting disposition of said ring fastener through said first aperture region.
According to a further embodiment, a method of securing an electrical meter to a meter socket box is provided comprising: providing an annular band, wherein a body portion of said annular band is divided to further comprise a first band portion and a second band portion; disposing a first tab member on said first band portion, wherein a first aperture region is formed through a body portion of said first tab member; providing a ring fastener having a first end and a second end; and disposing a ring fastener support member in structural cooperation with said ring fastener to support disposition of said ring fastener through said first aperture region.
In another example embodiment of the apparatus, the ring fastener support member is adapted to selectively align the ring fastener with the ring fastener receiver.

According to a specific, non-limiting embodiment of the invention, and referring now to
According to one example embodiment, annular band 100 is formed from a metallic material. In another embodiment, the band is extruded from a metal strip. In a further embodiment, the band material is rolled into the shape of an annular band. In a still further embodiment, the band is extruded from a solid rod. In other embodiments, annular band 100 is formed from a composite material, for example, from a hardened resin. In still other embodiments, annular band 100 is formed from plastic.
According to other aspects of the invention, apertures are formed in either one or both of the band's tab members to support installation of a ring fastening means. Forming apertures in the tab members is achieved in various embodiments by drilling, stamping, cutting or burning techniques, or using any other acceptable fabrication method available to one of ordinary skill in the art. In an alternative embodiment, only one ring tab member has an aperture portion formed therethrough, the other tab member comprising a complementary housing and nut assembly; in a further embodiment, the second tab member comprises a housing member for housing a rotatably secure fastener assembly.
Referring now to
Tab members 176, 178 also perform multiple functions. For example, in some embodiments, tab members 176, 178 comprise support structures for fastener combinations used to draw terminus portions 110, 120 tightly together. In other embodiments, tab members 176, 178 are used as grasping points by installers during assembly, and permit terminus portions 110, 120 to be drawn tightly together so that a fastener and receiver combination can be engaged. Once tab member terminus portions 110, 120 are tightly drawn and tab members 176, 178 are locked together, any subsequent attempt to tamper with the installed ring fastener and receiver assembly is significantly hindered.
Referring now to
In further embodiments, a wire seal is inserted through each of circular apertures 130, 140 in order to secure the tab members 176, 178 together. In still further embodiments, only apertures 150 and 160 are present, and a wire seal or a mechanical locking mechanism is used to hold the tab members together. In further embodiments still, tab members 176, 178 are secured by means of a mechanical lock, such as a padlock, a fastening end of which is inserted through each of two opposing apertures and then fastened into a body portion of the lock.
In
In various other embodiments, apertures 202, 208 are disposed at other axial locations on the receiving member, and not necessarily the opposed axial locations shown in
Returning to
According to further aspects of the invention, and referring now to
In one embodiment, support member 260 has an outer circumference that is smaller than an inner circumference of the aperture through which it is to be installed; in this embodiment, the head of gripping member 250 is also larger than a circumference of the aperture. In various other embodiments, support shelf 260 has a circumference of about the same size as the circumference of gripping member 250.
In certain embodiments, the gripping member is formed structurally integral with a ring fastener shaft member. However, in alternative embodiments, the gripping member is formed separately from the ring fastener shaft member and then attached to the shaft member using known attachment methods, for example, by gluing or welding the gripping member to a head portion of the shaft member, or by threading a threaded portion of the shaft member head into a thread receiving portion cut into an interior portion of the gripping member.
According to further aspects of the invention, and referring now to
Turning now to
In one example method, forming tool 350 is employed by feeding a threaded shaft portion of ring fastener 355 through an interior cylindrical portion of forming tool 350, and then pressing staking protrusion 360 against support member 370 with sufficient force to dent or otherwise deform the support shelf 370. When staking protrusion 360 is pressed against support member 370 with sufficient force to increase the outer circumference of support member 370, ring fastener 355 cannot subsequently be easily removed from the assembly. Thus, after such an operation, the support member would be suitable for supporting, in one example embodiment, the ring fastener 355 though an aperture (e.g., 130, 140) of a given tab member (e.g., 176, 178).
According to one embodiment, the force required for staking protrusion 360 to deform support member 370 varies in proportion to the characteristics of the material from which ring fastener 355 is made. In one example embodiment, the amount of force required for staking protrusion 360 to deform support member 370 is between around 250 pounds and around 1,000 pounds per square inch. In other embodiments, however, satisfactory staking results are achieved by using less than around 250 pounds of force per square inch. In applications in which ring fastener 355 is formed from a less malleable material, a force greater than around 1,000 pounds per square inch is required for staking protrusion 360 to deform support member 370.
In another example embodiment, the forming tool is adapted to engage at least a portion of a ring fastener receiver, such as for example, fastener receiver 300 as shown in
It should be recognized that various other example embodiments may provide that at least a portion of the apparatus may be adapted for use on various utility service enclosures, transportation or cargo containers or on other enclosures needing a securing apparatus (for example, in various embodiments having tamper-evident seal features) or a locking apparatus. Moreover, a utility service enclosure or other containers, for example, may have various compatible configurations, shapes and sizes (e.g., with the apparatus or at least a fastening portion of the apparatus) and be used in the electric utility industry, (e.g., a meter box) as well as in the gas, water, cable, TV utility industries or in the shipping or transportation industries.
In another example embodiment, at least a fastening portion (e.g., a cylindrical ring fastener and fastener receiver combination; fastener and receiver housings, any of various barrel lock devices, threaded or unthreaded-type attaching or fastening devices and systems or other types of fastening assemblies or components) or any of various elements of the apparatus may be adapted to secure a plurality of structures (e.g., having any of various configurations and being used with enclosures, utility service enclosures (e.g., electrical, gas, water, etc.), shipping or transportation containers (e.g., for use in land, air or sea transport) or cargo vessel panels or doors, or other types of panels (e.g., flat, curved or other security panels or the like), structures, or containers needing to be secured) with each of the plurality of structures in some embodiments defining an aperture therein or some fastenable structural component or feature. As noted, the plurality of structures having apertures may be any of a variety of structures. In one example embodiment, the plurality of structures comprise first and second ends of any of various types of ring meter socket rings, which may be connected or disconnected, with the ring being adapted to mount a meter to a meter box structure. Each of the first and second ends of the ring, in one example embodiment, defines at least one aperture therein respectively for use with the at least a fastening portion.
In other example embodiments tamper-evident sealing features may be provided. A seal may comprise the at least a fastening portion of the apparatus, in some embodiments configured similarly to a locking pin (or, in other example embodiments, various types of barrel locks, or as noted earlier herein) which is adapted to unite a plurality of structures. One example of such structures would be the ends of a meter ring having apertures. However, the locking pin could also be configured to be used to unite a plurality of structures, used with a utility service enclosure, or for example used to lock (and/or seal or create a tamper-evident seal to indicate tampering with), for example, utility enclosures doors, lids or other secured panels, meter boxes, or trucking, shipping, airline or other transportation or cargo containers or other enclosures. The plurality of structures could include plate-like structures having apertures, engageable protrusions, or other engageable structural configurations such that the plate-like structures could be united with the at least a fastening portion of the apparatus to secure enclosures used in various industries.
