Patent number: 4427219Abstract: A tubular fitting is threaded at one end for connection to a valve, meter, or the like and at the opposite end to a compression nut. A bore extends through the fitting and includes a tapered or restricted portion. The tapered portion forms an internal shoulder. A compressible sleeve is positioned in the fitting bore opposite the internal shoulder. A reinforcing insert extends through the sleeve. The insert abuts the end of the sleeve. An annular space is provided between the sleeve and the insert for receiving an unthreaded conduit. The insert includes a plurality of annular serrations adapted to frictionally engage the end of the conduit positioned in the annular space. The application of a force on the conduit in a direction to pull the conduit out of the fitting advances the sleeve against the fitting internal shoulder. The sleeve is compressed onto the flexible conduit to increase the frictional engagement of the conduit with the insert serrations.Type: GrantFiled: January 26, 1981Date of Patent: January 24, 1984Assignee: Robroy IndustriesInventor: Edward A.

Patent number: 4417711Abstract: A first clamp member and a second clamp member are positioned in opposed spaced relation with a conduit, pipe or the like, positioned therebetween. Each clamp member has a body portion including an engaging end portion adapted for attachment to a structural support and an opposite connecting end portion. An intermediate portion having an arcuate configuration extends between the engaging and connecting end portions and is adapted to receive and support the conduit. A moisture resistant, polymeric material covers the clamp member body portions so that the clamp members are completely encapsulated to seal out the effects of moisture. A bore extends through the connecting end portion of each clamp member. In assembly, the bores are oppositely aligned to receive a fastening element which draws the connecting end portions together for engagement of the intermediate portions with the periphery of the conduit.Type: GrantFiled: May 17, 1982Date of Patent: November 29, 1983Assignee: Robroy IndustriesInventor: Edward A.

Patent number: 4262409Abstract: A cable connector includes an insert having a tubular body portion with a conical end portion longitudinally spaced from an annular flanged end portion by diametrically opposed radial grooves. The insert is positioned in an aperture extending through a wall of an electrical junction box. The tubular body portion is contractable to permit the wall surrounding the aperture to be positioned in surrounding relation with the grooves to retain the tubular body portion in the aperture. A passageway extends through the tubular body portion and includes a rectangular inlet and a rectangular outlet. Vertical sidewalls of the passageway diverge outwardly from the inlet to the outlet so that the cross sectional area of the outlet is greater than the cross sectional area of the inlet. A pair of wedge shaped members are positioned in the passageway to secure a cable, such as an insulated conductor, extending through the passageway from being pulled out of the junction box.Type: GrantFiled: April 24, 1978Date of Patent: April 21, 1981Assignee: Robroy IndustriesInventor: Edward A.
