Karl Loehr has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7458846
    Abstract: A watthour meter socket adapter includes a housing having internal jaw contacts and external blade terminals. A power switch is electrically connected between the jaw contacts and the blade terminals. A rocker member on the power switch faces a side of the housing. An actuator is mounted in the housing and has a first end coupled to the rocker member for simultaneous movement of the rocker member and the actuator. A second end of the actuator extends through an aperture in the side of the housing allowing external manipulation of the actuator and the rocker member to indicate and/or manipulate the on and off state of the power switch. An electrically insulating safety shield may be mounted over the exposed portions of the jaw contacts and the conducting elements in the housing. Optional lock features may be provided to lock the actuator in the “on” or “off” positions.

  • Publication number: 20060160413
    Abstract: An electrically insulated body carries one of more jaw members which are mountable over threaded terminals in a meter socket to provide a bypass connection between line and load socket terminals to enable a watthour meter to be removed and reinstalled relative to the socket. In another aspect, the jaw members are coupled to an electrically conductive member. A handle extends from the conductive member.

  • Patent number: 5595506
    Abstract: A watthour meter socket adapter includes a plurality of rigid electrical conductors non-attachedly disposed in a housing. An electrical contact is mounted on a first end of each electrical conductor and is positioned within the housing for receiving a blade terminal of a watthour meter therein. A second end of each electrical conductor extends externally of the housing for insertion into terminals mounted in a watthour meter socket. An insulating sleeve mounted in the housing surrounds the portion of the electrical conductors extending externally of the housing, with the second ends of the electrical conductors extending outward from the sleeve. An electrically insulating plate is mounted within the housing spaced from a base of the housing. Apertures formed in the insulating plate receive individual electrical contacts on the conductors for positioning the electrical contacts and the electrical conductors within the housing to receive a blade terminal of a watthour meter.
