s claims. (Cl. 11o- 1) This invention relates tov curtain walls or slot arches, adjustable or ixed, for use with forging furnaces or as cutfoi or curtain walls to divide car type furnaces in one or more units, and lfor use at other points where the construction may be advantageous. The wall is also adapted for use, inv open hearth furnaces and soaking pits or wherever damper control is` desired in recuperative or regenerative systems or as a damper in -ues in breach- -ings for the stopping or retarding of gas iiow.

`One of the chief objects of the invention is` to provide a curtain or llink wall ywhich is suspended on aV metal support or grid, the wall preferably comprising side by side columns of refractory or tile having independent oscillation so that any vinter-mediatte section may swing if it is struck or contacts` a 'load` or a part of the furnace, without stressing Ior straining adjacent parts of the curtain wall.

Another object of the invention is tofproduce a curtain wall comprising independent sections: which can be swung out for maintenance or repair, and is -exible to allow lfor warpage, expansion or contraction independently of adjacent sections of the wal-l.

A further object of 'the invention` is to provide suspension means lof such nature tha-t the refractories can be made of rthe preferred material to. suit the furnace operating conditions. Heretotore, in many curtain walls where the refractory was. subject tol tension it has been necessary to sacriiice high :spaw-ling characteristics in order -to gain tensile strength. In other cases Where rcfra-ctory of high insulating property -should be used, older methods of support would not permit their use because of their lack of strength. Withythe support of thel invention, lhowever, `any type of refractory can be used, as each Itile is preferably carried as `a -un-i-t and` high tensile strength is not necessary. j

A -still further object of the invention is. toprovide an oscillatory curtain wall, which may be air orwater cooled as may be necessary under the operating conditions encountered.

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 of parts as hereinafter described and claimed; and in order 'that it may be fully understood, reference is to be had to the -accomp anying drawings, in which:V

Figure 16 is crossesection ythrough a similar wall in which water cooling is provided by a pair of pipes in telescoped position.

Figure 17 is 4a perspective view of a .tile hanger which may be used with either of the suspended pipe constructions.

In Ithe said drawings, where like reference characters identify corresponding parts in all of the figures, 1 is the side wall, 2.k the roof and 3 `t-he bottom of a furnace chamber. The curtain wall will be suspended by any suitable transverse support, lsuch as `a rotatable drum 4 or a beam 4a. With the `drum `4, .the wall may be vsupported by ilexible chains or cab'les I5v for llifting purposes. In the drawings, three dierent types of' oscillatory iwal-l supports are illustrated, namely, `Figure 1, a flexible chain; Figure 4, a specially :designed link suspension; and Figure 16, `a pipe or rod suspension, each of these constructions being hereinafter more particularly described.

Where 'link chains 5, `Figure l, are to form the supports for a series of flexible spaced independent columns of refractory forming a curtain wall, predetermined links Asupport 'ti-le hangers 6 of saddle type and projecting by preference in opposite directions paralleling the .axis of the overhead support. The saddle hangers are held in position by upwardly exten-ding iianges 7 which are clamped by a bolt 8 to a superposed link of the chain.

Where a linked construction other than a chainis to be used, Figure 4, the links may comprise elongated castings 9 having slotted hook ends 10. Engaging the hook ends 10 of the castings 9 are socketed open hook portions 12 on the tile hangers 13 which are preferably designed to support a pair of tile. With the construction shown it Will be evident` that as long as the device is. in tensionthe links and hangers are locked against accidental dislodgernent by sidewise movement.

Where a construction is desired which is rigid.v a rod or pipe 23, Figure. 16, may be used, said-v pipe beingsus pended for oscillation as will hereinafter appear, by preference. In this construction the tile hangers 24 are welded or otherwise attached to the pendant or vertical support.

The refractories or tile 11 to be used with the supports shown in Figures 1, 4 and 16, are illustrated in Figures 10 and 1l. The tile 1l isof generally rectangular form and has one of its faces provided with a longitudinal slot 14 which is intercepted adjacent one end by a socket 15 to receive the tile hanger. The lowermost tile of each column is preferably rounded as at .i6 to eliminate sharp corners which are subject to spawling.

If desired, the suspended tile may be of book form as shown in Figures 12 through 14, so that the individual tile of each column may have rocking movement on the adjacent tile. Intermediate tile of this kind is shown at 17. This tile has a longitudinal slot 18 in one face which is flared at 19 above thc hanger socket to accommodate the rocking movement in relation to superposed tile. The lowermost book tile 20 is also provided with a flared slot 21 above its tile hanger receiving socket 22 for permitting swinging movement of the tile as dotted in Figure l2.

Under some operating conditions it may be desirable to cool the refractory and metal supports by the circulation of gaseous or liquid cooling mediums. One means of circulating cooling air through the curtain wall is shown in Figure 4, where the lower tiles 16a are formed with transverse passageways 25. The longitudinal groove 14 of each tile communicates with the groove 25. One sidewall 2v of the furnace is formed with a through port 26 through which the air, under pressure or by gravity, is fed. By preference, a suitable packing 27 is inserted between the outermost column of tile and the furnace wall 2 as illustrated, but it will be noted that swinging movement of any tile column will interrupt air ow beyond the plane of such column. Of course, the cooling air may be omitted as indicated above, in which case the grooves and ports 26 will not be used.

If tiuid, such as water, is to be used as the cooling medium, the pipe support 23 may be capped as at 28 at its lower end. The upper end of the pipe is equipped with a two-way fitting 29 which is connected at one side to a water inlet exible tube 30 which leads to the capped lower end of the pipe 2.3. Water is discharged by tube 3) circulates upwardly through the pipe 23 and out through a flexible connection 31 to a manifold 32 carried by the overhead support or beam da. Inlet tube 30 is fed from a supply manifold 33 also carried by beam 4a. One method of suspending the pipe for oscillation is to equip its tting 29 with an eye 34, said eye receiving a U- bolt 35 carried by the beam 4a.

An alternate water cooled wall is shown in Figure 15, Where pipe 36 is formed in a U-support. One leg of the U-support is connected by flexible tube 3/ to a water feed manifold 38, and the other leg is connected by exible tube 39 to an outlet manifold 4t). The

tile

41 and 42 as used in this construction are identical with those numbered 11 and 16, except their abutting faces are formed with parallel grooves to accommodate the two legs of the pipe. In this arrangement the upper ends of the U-pipe are attached to a cross-bar 42a which may be suspended for oscillation with an eye-bolt 43 and U-clip 44.

In considering the above description and drawings it will be apparent that the double pendant support for each tile as where the U-pipc is used, may be modified by substitution of a plurality of parallel chains 5 or links 9-10- This multiple suspension is particularly desirable with thick or high-refractory walls where the load on the oscillating support is fairly heavy as such multiple suspension divides the load between the pendant supports and lessens the tendency to yield or creep at high temperatures.

From the above description and drawings, 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 construction, it is to be understood that I reserve the right to all changes within the spirit and scope of the appended claims.
