rommel: WALL Application led October 30, 1925. Serial N0. 65,767.

My present invention relates to furnace walls and provides a highly important improvement in the type wherein a single replaceable wall is anchored to outside vertical columns or metallic buckstays, Generally stated, the invention consists of the novel devices, combinations of devices Y and arrangement of parts hereinafter described and defined in the claims.

.A wall of this character will preferabl be built up entirely of fire brick, althoug if the wall be made of sufficient thickness, some common bricks may be incorporated in the outer portion thereof. The Wall, however, is a single wall that may be replaced either in part or as an entirety.

In the accompanyingv drawings, which illustrate the invention, like ,characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a fragmentary perspective showing a furnace wall designed in accrdance with my invention, some arts thereof being removed and some being broken away;

Fig. 2 is a fragmentary plan view showing one of the buckstays and a portion of the wall anchored thereto;

Fig. 3 is a section taken on the line 3-3 of Fig. 2; s]

Figs. 4 and-5 are perspective views show-- mg certain of lthe specially constructed blocks of the wall illustrated in Figs. l, 2 and 3;

Fig. 6 is a perspective showing one of the metallic block anchors;

j Fig. 7 is a view corresponding to Fig. 1, but illustrating a slightly modified construction of the wall; and

Fig; 8 is a perspective showing bne of the specially constructed blocks used in the structure illustrated in Fig. 7.

Describing first the structure illustrated in Figs. 1 to 6, inclusive, the numeral 9 indicates thel vertical buckstaysv, which, as shown, are inthe form of upright rolled steel beams. The numeral 10 indicates a metallic casing shown as applied to the exteriors of the buckstays 9. v

The refractory wall is made up of lhorizontal belts of lire brick and interposed horizontal rows of sill blocks or tiles, the latter of which are anchored to horizontal ledge plates, which latter are interlocked to the buckstays. The horizontal belts of brickwork, in this structure, are shown as made up of bricks 11 laid as headers. and bricks 12 laid as stretchers. Between each of these tilting or lateral shiftin horizontal belts is laid a horizontal row of the sill blocks or tiles 13 and 14 that`are preferably much larger than common bricks, in depth, width and length.

For anchoring the sill blocks 13 and 14 to the buckstays, there are providedhorizontally extended ledge' plates or bars 15, which, at their inner edges, have upturned lock flanges 16 and, at their outer edfres, have downturned lock flanges 17, which latter are seated between the inner faces of the buckstays and offset upwardly projected ends of anchor brackets 18 riveted or otherwise rigidly secured to the several buckstays. The sill blocks 13 and 14 are laid on the ledge plates 15 with their inner half portions more or less projecting inward of said ledge plates. These blocks 13 and 14, on their under sides, are formed with grooves 19 that receive the upturned flanges 16 of the `ledge plates. The blocks 13 that are laid adjacent to the buckstays are also formed in their upper faces with longitudinal lock grooves 20 and with `transverse lock grooves 21 that are adapted to receive the T-shaped inner ends 22 of'flat metallic anchors 23, which latter are formed with hook-like outer ends 24. When these anchors are applied in the grooves 20'21, as shown in Fig. 2, with their hook-like ends 24 engaged with the flanges of adjacent buckstays, it is evident' that the said blocks 13 will be securely an. chored to the buckstays both at their top and bottom portions and, hence, will be held in horizontal positions even if some or all of the bricks of an underlying belt may be removed. The intermediate blocks 14, while not as securely anchored as the blocks 13 against tilting movements, are, nevertheless, locked to the ledge plates against horizontal shifting movements, and when engaged by an overlying belt of bricks that form a bridge between the spaced blocks 13, said intermediate blocks 14 will also be prevented from tilting, even whenhricks of an underlying belt are removed. Moreover, it will be noted that one-half or more of the weight of the blocks 14 is on the ledge plates, so

that there is little, if any, tendency for the same to tilt.

By the means describedthe brick wall is held Lin perfect alignment and anchored to the buckstays and thus securely held against movements. The ledge plates 15 are pre erably Alaced with thelr abutting ends lapped wit the inner flanges of the buckstays and with the anchor brackets 18.

lu the wall illustrated in Figss 1 2 and 3, the blocks 13 and 111 do not extend in the wall to the inner or fire-exposed surface thereof and, hence, the spaces between the belts of brick 11-12 that would otherwise be left are filled .in with fire bricks 25.

ln some instances, the grooves 21 of thev in accordance with a standard that is predetermined or known,

'lhe wall illustrated in lfig. 7 is much like that illustrated ,in Figs. l, 2 and 3. The lower portion thereof is of the identical con- 25 struction except that in one horizontal row the sill blocks 13 and 14 are estende through to the inner face of the wall.. ln this wall, the lower portion is much thicker than the upper portion and, hence, on the upper belt of bricks 11-12, there is placed a layer of beveled wall-reducing sill blocks 2G. 'l`hat portion of the wall above the sill blocks 26 is shown as made up of belts of fire brick 27 laid`as headers and an interposed horizontal row of sill blocks 13a and 6wplacedw Of Icourse, the sill 14, 'lhe blocks 13 and 1liEl are like the blocks 13 and 1li of the wall illustrated in Figs. 1, 2 and 3, except that, as shown, they are provided at their adjacent edges with interlocking joints 28. 'llhe blocks 13B are anchored to the buckstays by the metallic anchors 23 in the same manner as are the blocks 13. From statements made, it of course follows that the blocks 139' and 14 are grooved and inter-locked to the ledge platesr the same as before described in conection with the blocks 13..

lt should be noted that the ledge plates 15 are detachably interlocked to the buckstays so that they may be readily replaced, section by section, if damaged or warped by the heat. Of course, when blocks are placed on the ledge plates, they will be positively and firmly anchored to the buckstays and blocks that normally rest thereon must be removed before they can be detached from the buckstays. n

lin the wall structures described, it is evident that" all of the brickwork or masonry of the wall may be very readily replaced and that any part of any one belt may be removed without disturbing adjacent upper and lower belts, and, moreover, that the sill llocks themselves may be very readil reloeks t eini,eae,ise

tically spaced rows, and belts of brick-work betweenthe horizontal rows of sill blocks.
