Reintjes, Kansas City, M0. 7 Application December 15, 1952, SerialNo. 326,037

5 Claims. to]. 72-19 This application is a continuation in part of my application for patent for Wall Facing, filed October 29, 1951, Serial No. 253,586, now abandoned, and relates to tile or refractory linings or facings for test cells, chambers or vessels of various kinds, such as test units used for rotary and jet engines where considerable blasts of air or hot gases or fluids are exhausted, and is also useful in catalyst towers and other refinery installations Where the air or gas may or may not entrain solids. The walls of such chambers are subject to vibration and the linings must be tight so that they cannot be undercut or penetrated by the gases.

Another object of the invention is to provide means for facing or lining suchchambers so that the lining can be supported in a smooth plane regardless of the irregularities which may exist in the supporting wall or structure.

A further object of the invention is to provide a refractory lining in which the individual tile or units are locked mice is threaded for engagement with the supporting bolt rather then having a separate nut .as in Figure 2, and the tile clamping members have supporting flanges and pressure padsspaced from the margin of the tile.

Figure 7 is a face view of the construction shown in Figure '6.

against inward or outward movement, but are free for expansion due to temperature changes. The tile are also provided with means to hold a suitable packing to guard against penetration by the air blasts through the lining into the space which may exist between it and'the supporting wall. I I I A still further object of the invention is to produce a construction in which the tile are laid up in courses, each course being supported by flanges on a pair of clamping members which hold the tile against vibration atipoints spaced from their margins, the supports being of such nature that they cannot rotate independently ofthe tile held thereby. Another object is to produce a construction in which one or more tile can bereadily removed or replaced as found necessary.

With the general objects named in view and others as will hereinafter appear the invention consists, in certain new and useful features of construction and organization Figure 8 is a face view of the construction shown in Figure 6 with the outer clamping member omitted.

Figure 9 is alongitudinal sectionthrough the bolt as illustratedin Figure 6.

In the said drawings,*where like reference characters identify corresponding parts in all of the figures, 1 is the wall of a chamber to be lined and projecting therefrom, in spaced rows, are a series of .bolts or rods 2, which are preferably threaded at their ends as shown. By preference, the bolts 2 project a sufficient distance to pass entirely through the tile lining and any insulating blanket as shown in Figures 1, 2 and 6, but where the bolts are too short, the construction shown in Figure 4 may be employed.

The supporting bracket of the invention essentially comprises a spool-shaped member, the space between the flanged ends of the spool being adjustable to accommodate the thickness of the refractory or tile lining, said bracket being carried by the spaced bolts 2. Three modifications of the spool supporting bracket are shown in the present application, namely (a), the construction of Figure 2 where the support comprises one flange integral with the stern portion of the spool, said stern member being adjustably secured to the bolt by a separable nut, the other flange of the spool being a clamping plate secured in position by a nut; (b), the construction of Figure 5, where the .bolt 2 isshort and engages internally threads in the stem of the spool bracket, the outer clamping flange being held in position by a stud bolt threaded into the stem I of the bracket; and (c) Figurev6, where the bracket stem is of parts as hereinafter describedand claimed; and in order had to the accompanying drawings, in-whi'chi '5! Figure 1'-is a perspective view, partly broken away, illustrating one methodbf applyinga refractorylining involving the invention, an insulating-and/ or sound deaden'ing blanket of plastic-orother-material being positioned between the tile andthe supportingwall, and the joints between the tile being packed against leakage.

Figure'Z is an exploded perspective view of the tile liningand supporting parts.

' Figure 3 is a cross-sectiontthr'ough the tile supporting brackets of Figure 2. i

Figure 4 is a diagrammatic section to show the application of the support of, the invention to an irregular 2 is of insufficient length to extend through the tile-lining; Figure 6 is a section through a tile lining embodying a modified construction and illustrates a support substan tially the same as 'in Figure 2, except the inner bracket internally threaded to'engage the bolt 2, the outer flange of the spool-being also held by a clamp nut, both inner andouter flanges of the spool having edge or shelf flanges for the tile lining to rest upon, and clamping pads spaced from the edge of the dle to prevent tile. cracking on application of pressure. t 7

Referring now to the construction of Figure 1, the spool shaped.bracketcompfiseslinner and outer flanges 4 and 5, together with the center or "stem portion 3 which is shown as integral with theflange 4. @Thestem' 3 is tubular and has a side opening] receiving a nut 8, which is in threaded engagement'with' the bolt 2. After the spool bracket '34 has been brought into proper position on the bolt 2, the tile 6 formed with transverse notches 8a. accommodating tliebracket.and'longitudinal' grooves 11 to receive the joint sealing or packing ope-.10, are placed in courses. The tile 6 are new clamped in position by placing the outer flange member 5 on the bolt 2 and} turning home the clamping nut;9. Withthis arrangement it will be apparent that the tile. can belaidHu'pcourse by course, the upper edge of each tile being held in position by the flanges 4 and 5' of the" superposed tile course. .LIf desired, the stem 3 may be of Maltese cross"shape"t6 distribute the load on the bolt 2 and for weight-reducing purposes. In some installations a heat insulating and sound-deadening blanket 12 may be positioned between the lining and the supporting wall 1. In Figure 5 where the bolts 2 are too short to go through the lining 6, the tile bracket is formed with inter in which the bolt 2 extends entirely through the lining tile 20. In this construction the rear flange 21 is shown as of rectangular, rather than circular shape, and it is formed integrally with a forwardly projecting tubulai stem 22 which, as illustrated, terminates in a hexagonally wrench-engaging end 23, the tubular stem 22 being internally threaded for the width of said hex head for engagement with the threaded bolt 2. The flange 21 is formed with a forwardly projecting transverse flange 24, and the lower edge of the tile is provided with a cross notch 25 corresponding to the notch 8a of Figure 2. The tile are also formed with edge not-ches'26 to accommodate the flanges 24, so that the'weight of the tile is supported both by the flange 24 and by the stem 22 of the bracket. V

The outer flange 27' is also preferably formed with an inwardly projecting stern portion 28 to fit in the notch 25 of the tile 20 and with a horizontal shelf flange 29 received within the notch 26. Theflange 27 is bolted into clamping relation with the outer face of the tile by a nut 39 which is locked against rotation by a locking plate having a pair of ears 31 bent between the ribs 32 of the flange 27 and a second pair of cars 33 embracing opposite sides of the nut 30. Any other means of locking the nut may be used, or a self-locking nut may be employed. In this construction 'it is to be noted that the outer and inner clamping flanges 32 and 21 are formed with a pair of clamping pads 34 which contact the faces of the tile at points spaced from the tile margins. This arrangement better distributes the pressure and avoids cracking or injury to the tile as they are clamped in position. The construction is completed as the courses are laid by providing the packing rope 10 in the longitudinal grooves 11 formed in the edges of the tile. 1

From the above description it will be apparent that I have produced a construction embodying all of the features of advantage set forth as desirable, and while I have described and illustrated the preferred embodiment, it is to be understood that I reserve the right to all changes within the spirit and scope of the appended claims.
