Patent number: 11441079Abstract: Methods and systems for constructing a refractory wall structure having gas flue spaces are provided. In certain embodiments, a first course of the wall structure may be constructed by installing opposing refractory side wall panels that are separated by a distance which defines a widthwise dimension of the wall structure and an interior wall space therebetween. The side wall panels may include multiple sets of finger forms defining a joint space (e.g., a dovetail joint space), whereby the finger forms protrude inwardly into the interior wall space such that the sets of finger forms of one side panel are oppositely positioned relative to the sets of finger forms of an opposed side wall panel.Type: GrantFiled: October 2, 2019Date of Patent: September 13, 2022Assignee: FOSBEL, INC.Inventors: Alan E. Bowser, Jr., Mike Cofield

Patent number: 11180350Abstract: Methods and apparatus for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures having walls formed of refractory block and buck stays externally supporting the walls are provided. Opposed pairs of supports are connected to at least a respective one of the vertically oriented buck stays with cross-support beams spanning the refractory structure between a respective pair of the supports. An overhead crane assembly is supported by the cross-support beams. In such a manner, refractory components of the refractory structure (e.g., refractory wall blocks and/or refractory checker bricks) may be installed using the overhead crane assembly.Type: GrantFiled: January 30, 2019Date of Patent: November 23, 2021Assignee: FOSBEL, INC.Inventors: Robert D. Chambers, Michael P. Smith, Alan E. Bowser, Jr., Kevin D. Pendelton, Lou Carolla

Patent number: 10407333Abstract: Methods and apparatus are provided for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures formed of refractory components, by positioning opposed pairs of vertically oriented base beams on respective opposite sides of the refractory structure and having a lower end rigidly attached to a foundation of the refractory structure and an upper end which extends vertically above the refractory structure, and attaching cross-support beams to respective ones of the base beams at the upper end thereof so as to latitudinally span the refractory structure. An overhead crane assembly may thus be supported by the cross-support beams.Type: GrantFiled: February 2, 2016Date of Patent: September 10, 2019Assignee: FOSBEL, INC.Inventors: Lou Carolla, Michael Smith, Alan E. Bowser, Jr.

Patent number: 10364174Abstract: Glass furnace regenerators having opposed pairs of side and end walls formed of refractory blocks, wherein at last one of the side and end walls of the regenerator comprise an interlocking plurality of refractory blocks, and wherein the refractory blocks are self-supporting and load-bearing one-piece pre-cast structures of a refractory material. Tie back bars may be provided to operatively connect a wall formed of the refractory blocks to externally provided buckstays to allow relative movement between the refractor blocks forming the wall and the buckstays (e.g., as may be required due to the blocks undergoing thermal expansion during use).Type: GrantFiled: February 14, 2017Date of Patent: July 30, 2019Assignees: FOSBEL, INC., DSF REFRACTORIES AND MINERALS LIMITEDInventors: Trevor Robert Wilson, Alan Bowser, Lou Carolla

Patent number: 10336942Abstract: Coke oven corbel structures include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues and a plurality of diagonally oriented lateral flues. At least one tier of refractory blocks in the assembly includes a plurality of tongue-and-groove interconnected refractory blocks. This plurality of interconnected refractory blocks of the at least one tier comprise mutually substantially orthogonal faces defining an edge and respectively including an elongate tongue protruding outwardly therefrom and an elongate groove recessed therein. The elongate tongue and groove include respective adjacent ends which co-terminate with one another at the edge defined by the mutually orthogonal faces of the refractory blocks.Type: GrantFiled: November 20, 2015Date of Patent: July 2, 2019Assignee: FOSBEL, INC.Inventor: Alan E. Bowser, Jr.

Patent number: 10294085Abstract: Methods and apparatus are provided for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures formed of refractory components, the refractory structure being housed within a building having a roof support elements. Cross-support beams are provided to latitudinally span the refractory structure and are suspended from roof support elements associated with the building housing the refractory structure by a suspension support system attached to the cross-support beams. An overhead crane assembly may thus be supported by the cross-support beams.Type: GrantFiled: February 2, 2016Date of Patent: May 21, 2019Assignee: FOSBEL, INC.Inventors: Lou Carolla, Michael Smith, Alan E. Bowser, Jr.
