  • Patent number: 6518871
    Abstract: A hot stick switch head for a lineman's tool for safely and expeditiously removing and installing fuseholders having a tubular body and a mounting assembly from an overhead mounting comprising a base member having a downwardly depending attachment device for attachment to the end of a hot stick and an elevated slot member on the opposite end thereof for receiving an element of said mounting assembly, and a fusebody-receiving notch. A laterally projecting arm engages a fusebody anywhere along the length thereof an guides the fusebody into the fusebody-receiving notch in the base member. The notch and slot are shaped and juxtaposed relative to each other so that on vertical elevation of the lineman's tool, the fusebody is securely retained thereon while the fusebody is lifted out of the fusebody mounting.

  • Patent number: 4872847
    Abstract: A pilfer proofing system for electric meter boxes having a meter base box which carries a plug-in terminal block set and a meter box cover having an opening through which a plug-in meter passes to engage contact female or socket terminals in a terminal block set. A contact terminal block adaptor carrying insulating cages frictionaly retained in the female socket terminal of the contact block set springs are included in the female socket terminals to assure continuous electrical contact and avoid hot spots. The meter box has a pair of lateral meter stops which are clamped between one end of an annular, cast aluminum ring and a pair of insulated, bifurcated clamp bars positioned behind the meter stops which, in turn, are secured to a common metal bar housed in a recess in the adaptor. The illustrate clamp bars have bifurcated ends which more evenly distributes the mechanical forces to the meter box by providing a plurality of distributed contact or load distribution points instead of one.

  • Patent number: 4404521
    Abstract: A pilfer proofing system and method for electric meter boxes having a meter base box, which carries a plug-in terminal block set and a meter box cover having an opening through which a plug-in-meter passes to engage contact jaws or sockets the terminal block set. An anchoring bar is secured to the meter stops and a conventional meter locking collar is secured to the cover and the bridge of the locking collar is secured to the anchoring bar. Metal extension adaptors are secured to the meter blades for entering into the contact jaws or sockets of the terminal block set and a conventional locking ring is utilized to lock the meter in place on the added meter collar thereby providing a substantial obstacle to easy pilfering of electricity.
