Publication number: 20230408361Abstract: A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Inventors: Dennis L. HART, Cristobal GONZALEZ, Virgil E. O'NEIL, Jeffrey A. JARAMILLO, Larry D. BROWN

Patent number: 11781677Abstract: A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.Type: GrantFiled: March 29, 2021Date of Patent: October 10, 2023Assignee: RELIANCE WORLDWIDE CORPORATIONInventors: James W.

Patent number: 11698158Abstract: An assembly creates annular voids in concrete around the distal end of cylindrical tubes. A cap has a flat top and a cylindrical, depending skirt. An annular, foam plug extends between the inside of the skirt and the outer diameter of the tube. The plug has an undeformed inner diameter smaller than an outer diameter of the tube to create an interference fit around the tube and keep concrete out when the cap is on the end of the tube. The plug has a radial thickness of 0.3 to 1 inch, and has an axial length of 1 to 3 inches, with a bottom of the plug located at a bottom of the skirt. The cap is glued to the end of the tube for pressure testing. After the tube is entrained in concrete, the cap and plug are removed to leave a void in the concrete surface.Type: GrantFiled: January 12, 2022Date of Patent: July 11, 2023Assignee: RELIANCE WORLDWIDE CORPORATIONInventors: Virgil O'Neil, Dennis L.

Patent number: 11186986Abstract: A sleeve assembly for poured concrete decks has a tubular sleeve connected to a base flange by stiffeners or an optional base wall. An intumescent ring and fire ring plate are fastened to the base flange. The stiffeners and optional base wall are configured so concrete passes between the stiffeners to entrain a fire ring plate and ring of intumescent material in the concrete by passing through a gap between the base wall and the sleeve or through open windows in the base wall to entrain the base wall when it is present.Type: GrantFiled: September 26, 2019Date of Patent: November 30, 2021Assignee: Reliance Worldwide CorporationInventors: James W.

Patent number: 10656042Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position.Type: GrantFiled: August 11, 2016Date of Patent: May 19, 2020Assignee: Reliance Worldwide CorporationInventors: Dennis L.

Patent number: 10344472Abstract: A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.Type: GrantFiled: October 24, 2016Date of Patent: July 9, 2019Assignee: Reliance Worldwide CorporationInventors: Timothy M.
