Assignee:

Ekstrom Industries, Inc. - Farmington Hills MI

International Classification:

H01R 33/945

US Classification:

439518, 439508

Abstract:

A watthour meter socket adapter carries rigid conductors extending from a connection to jaw contacts in a housing, the conductors mounting the socket adapter between the lower load mounting connections and the upper line mounting connections in a meter fitting to define an in-service metering position where the socket adapter and the watthour meter are disposed in the normal out-of-service, non-metering position in the meter fitting. The socket adapter housing is spaced from a ground terminal insulating block mounted over a ground terminal in the meter fitting. In another aspect, a plurality of current transformers are carried on a plate which mounts in an existing K-series meter fitting line and load terminal connections footprint.

Assignee:

Ekstrom Industries, Inc. - Farmington Hills MI

International Classification:

H01R 33/945

US Classification:

439517, 439146, 439508

Abstract:

A watthour meter socket adapter has housing formed of snap together rear and front housings. The front housing surrounds but allows access to jaw contacts and terminals mounted in the rear housing by a watthour meter and electric power conductors. An aperture in the front housing engages a socket adapter mounting fastener extendible through the aperture to attach the socket adapter to a mounting surface. The fastener and aperture resist separation of the front housing from the rear housing when a watthour meter is removed from the socket adapter. A clip extends from the front housing through an aperture in a terminal cover attachable to the front housing and receives a seal lock member. Another clip on the front housing extends through the terminal cover and is engaged by an expandable ring lock clip. A meter surge guard is removably mountable to the rear housing and exteriorly of the front housing.

International Classification:

E05B 67/02
E05B 67/06
B23P 11/00

US Classification:

70 52, 29428

Abstract:

A lock apparatus includes a lock body which is slidably mountable over the legs of the shackle. At least one push nut is mounted within a recess carried in the lock body to allow easy insertion of the legs of the shackle through the bores in the lock sections and the at least one push nut, but exerts a substantial force resisting separation of the lock body from the shackle in an opposite direction. The lock body is formed of a unitary one-piece body, or a pair of identical lock sections which are reoriented with respect to each other and inter-engaged to form bores at one edge which receive the legs of the shackle. A method of installing the lock apparatus includes mounting at least one push nut in a lock body and then inserting the legs of the shackle through bores in the lock body and the at least one push nut.

Assignee:

Ekstrom Industries, Inc. - Farmington Hills MI

International Classification:

G01R 104

US Classification:

324 74

Abstract:

A load indicating socket tester includes a base and an annular sidewall. A plurality of pairs of line and load terminals are mounted in and extend outward from the base for removable insertion into electrical contact with jaw terminals in a watthour meter socket. A cover closes an open end of the side wall of the housing and has fuses, lamps, an amp meter, and a lamp test switch mounted thereon. The fuses and lamps are preferably provided in pairs and electrically connected with the lamp test switch such that the switch, when in a first position, connects each lamp in parallel with one of the fuses and, when in a second position, electrically connects each lamp in series with one of the fuses to test the operation of each lamp. A current transformer is mounted within the housing and detects the current drawn by a load when the socket tester is mounted in a watthour meter socket. The output of the current transformer is connected to the amp meter to enable the load current to be visibly displayed externally of the cover of the socket tester.

International Classification:

H01R 2900

US Classification:

439167

Abstract:

A service disconnect adapter mounted between a plug-in meter socket and a watthour meter. The service disconnect adapter has blades mounted on a base which engage terminals in the socket. Watthour blade receiving fingers are formed in the service disconnect adapter to receive and frictionally engage watthour meter blades. The service disconnect adapter electrically isolates the socket load terminals from the watthour meter blades to disconnect the watthour meter from the load side terminals of the socket. The blades are angularly offset from the watthour meter blade receiving fingers in the adapter to mount the watthour meter at an angle from its normal mounting position. A pair of electrically conductive jumpers are mounted on and extend through the base in the adapter and are electrically connectible between the socket line terminals and the selected ones of the watthour meter contact blades to connect electric power to the watthour meter while the watthour meter load contact blades are disconnected from the socket load terminals.

International Classification:

E05C 1918

US Classification:

29225667

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.
