Publication number: 20030197378Abstract: A compression connector for sealingly connecting a fluid line to a plumbing fitting, valve or connector. The connector assembly sealingly retains the tubing within the device to direct flow therethrough. The plumbing fitting includes a seat for matingly receiving the tubing in fluid communication with the interior passageways of the fitting. With the tubing seated in the fitting, a compression ferrule and a compression nut are coaxially mounted to the tubing. The compression ferrule includes wedge-like edges at both the leading and trailing ends thereof. The compression nut has an angled shoulder configured to engage the trailing edge of the ferrule. As the nut is rotated onto the fitting, the angled shoulder deflects the trailing edge of the ferrule radially inwardly into engagement with the tubing. Similarly, the leading edge of the ferrule is deflected radially inwardly into engagement with the tubing. The dual deflection edges create a sealing connection of the tubing within the fitting.Type: ApplicationFiled: December 10, 2002Publication date: October 23, 2003Inventors: Bradley E. Allstead, Robert O. Learmont, Donald S. Glover

Patent number: 5588874Abstract: A watthour meter adapter includes jaw contacts for receiving blade terminals of a plug-in watthour meter. Apertures formed in an annular side wall of the adapter housing receive external line and load conductors therethrough. A terminal block disposed within the annular side wall at a lower portion of the housing receives the external line and load conductors as well as internal electrical conductors connected at opposite ends to the jaw contacts. A slot formed in a bottom wall of the housing receives a fastener to mount the housing to an external support surface. The terminal block and terminal connections as well as the mounting fastener are completely contained within and covered by a watthour meter when a watthour meter is mounted on the adapter.Type: GrantFiled: April 7, 1995Date of Patent: December 31, 1996Assignee: Ekstrom Industries, Inc.Inventors: Allen V.
