Patent number: 11713882Abstract: A fireplace construction made of solid masonry units having a rear wall with a symmetrical bulge formed by a lower angled portion, a central vertical portion, an upper angled portion, and an upper vertical portion. Each portion is slightly spaced apart from the adjacent portion to provide a space for air to flow into the firebox. One or more air ducts route air from the room to the space between both the lower vertical portion and the lower angled portion and the space between the lower angled portion and the central vertical portion.Type: GrantFiled: March 15, 2021Date of Patent: August 1, 2023Assignee: Meredith Group, LLCInventors: Christopher C.

Publication number: 20230011450Abstract: A retrofit firebox assembly includes a frame, a floor, and sidewalls. The frame has a plurality of vertically extending spaced apart tube members to which solid masonry units are mounted. The back wall has a metal plenum member with a lower vertical portion, a lower angled portion, a central vertical portion, an upper angled portion, and an upper vertical portion, positioned to form a smooth, symmetrical bulge in the back wall extending into the firebox. The solid masonry units are positioned on their respective frame members using clips that position, align, and support the units. The metal plenum provides spaces for air to flow into the firebox between the lower vertical portion and the lower angled portion; and between the lower angled portion and the central vertical portion.Type: ApplicationFiled: September 15, 2022Publication date: January 12, 2023Inventors: John E.

Publication number: 20170059157Abstract: A device for cleaning a chimney preferably includes a rod assembly, cleaning arms, fan blades, a camera, and a stabilizing/positioning assembly. The cleaning arms are provided on an assembly that includes a rotatable hub with the cleaning arms extending from the hub. The fan blades may also extend from the hub or they may be provided separately. The camera is continuously rotatable around the longitudinal axis to allow an uninterrupted 360° scan of the chimney. The stabilizing/positioning assembly is effective to position the cleaning assembly hub a pre-selected stabilizing/positioning distance from an interior wall of a chimney while the hub rotates in the chimney. The cleaning and fan hub(s) is driven by a cable surrounded by a casing that allows the cable to rotate in the casing without rotating the casing. Controls allow the operator to control the speed and direction of the cleaning arms and the camera.Type: ApplicationFiled: November 15, 2016Publication date: March 2, 2017Inventors: John E. Meredith, Thomas J. Urban

Patent number: 8329074Abstract: A device for repairing a chimney preferably includes a rod effective for positioning and manipulating a camera and a plunger blade in a chimney; a camera attached to the lower portion of the rod in a manner such that rotation of the rod results in a corresponding rotation of the camera; and a plunger blade attached to the rod above the camera. The plunger blade is adapted to apply mortar to the sides of a chimney when the device is pulled upward in the chimney. The device may further include a camera-direction indicator attached to the rod above the plunger blade in a manner such that the camera-direction indicator is effective for indicating the direction of view of said camera even when the camera is not visible to the operator.Type: GrantFiled: May 21, 2009Date of Patent: December 11, 2012Assignee: Merediths' Inc.Inventors: John E.

Publication number: 20120005984Abstract: A method of relining a chimney includes: inserting a sleeve into a chimney; subsequently coating the sleeve with a flowable refractory material while the sleeve is positioned in the chimney. The flowable refractory material hardens on the sleeve to provide a refractory surface on the inner surface of the sleeve. The sleeve may be flexible or rigid, and may be lined with an insulating material. A high-temperature resistant fabric with an aluminum foil outer liner is preferred. The flowable refractory material may be a blend of inorganic materials and inert aggregates together with a high temperature resin bonding agent. The inert aggregates may include 50-80% Al2O3 and 10-40% SiO2.Type: ApplicationFiled: September 19, 2011Publication date: January 12, 2012Inventor: John E. Meredith
