P. MCKENZIE FURNACE WALL I Filed March 28, 1927 Nov. 20, 1928.

QNITED srA PETER MCKENZIE, OF CHICAGO, ILLINOIS.
FURNACE WALL.
Application filed IIarch 28, 1927. Serial No. 179,088.
This invention relates to the construction of furnaces or other combustion chambers and particularly to sectional supported furnace walls. The principal object of the present invention is to simplify and to improve such construction by supporting the tiles upon brackets which are free to slide either way upon their supports with the expansion of the wall.
Astill further object of the present invention is to provide a method of supporting furnace tiles in such manner as to increasegreatly the life of the wall and without corresponding increase in the cost of the -wall. Other objects of the invention relate to specific, details of construction and in general to the ability to replace a tile from any part of the wall by removing the wedge tile between two regular tiles.
In the drawings Figure 1 is a perspective of a furnace wall embodying the invention. v
Figure 2 is a side elevation of a bracket.
Figure 3 is a plan of Figure 2.
Figure dis a cross-section.
The general lay-out is well illustrated in the perspective view, Figure 1, in which the numeral 10 indicates the inner or firebrick wall formed of special tiles, and 11 indicates the outer wall con tructed of bricks customary in such install ions, the two walls being spaced to provide a space from which the hot air is drawn to the furnace, thus considerably aiding combustion. The vertical rolled steel sections 12, preferably I-beams, are embedded in the masonry of the outer wall and at regular intervals carry small supporting brackets 13 permanently attached thereto as by the rivets shown. The various i as illustrated.
supporting brackets at each level support the rails 14', here shown as angle irons, and which form the sole retaining means for the brackets '15 shown in detail in Figures 2 and 3.
The body of each hanger, or bracket as it is technically *called, is I-shaped in horizontal cross section with parallel front and rear flanges, 20 and 21, respectively, integral with the central web 22. An integral shelf 25 extends forwardly from the front flange 20 and is of suficient size to provide ample support for the eight tiles which rest upon it Each bracket is supported against gravity I by a hook26 extending rearwardly from the topof the flange 21, the notch of the book being of such size as to receive loosely the vertical flange of the supporting angle or rail, and is retained by the loose engagement of the next lower rail in the relatively deep slot 28 in the foot 29 which is an integral, rearwardly and downwardly projecting portion of the rear flange of the body of the bracket. The upper rail fits into the crotch of the slot of the hook 26 but the lower rail does not touch the crotch or upper margin of the slot, consequently an expansion of the bracket cannot buckle either rail nor tend to alter the fixed distance between adjacent rails, and similarly the individual bracketsare each free'to move either up and down or side to side with respect to either rail. as the tiles of the inner wall 10 expand and contract.
The tiles are of several types, those numbered 30 having straight slot to receive that portion of the flange 20 extending to one side of the web 22 while the tiles numbered 31 in addition to the flange receiving slot are cut away to receive the web as mostclearly seen by reference to Figure 4. Tiles33 do not engage the 'brackets oftheir own tier but are directly over and centered with respect to the brackets of the tier beneath and are each removable from the inner face of the wall 10. Tile 3a is a special form and only one tile of this type is used in each section. As seen in Figure 1 this tile extends from the inner face of wall 10 to the inner face of wall 11 and has at its rear an angular extension projecting behind a bracket engaged tile 30. 1
"To remove any tile except 34 the adjacenttile 33 of the course is pulled directly out, the worn tile is then slid sideways until its slot is. free of the bracket and then pulled forward until it is free. To remove a tile 34 it is first necessary to remove the tile 33 below and then the tile 30 to the right. Tile 34 is nowlowered to the place justoccupied by tile 33 and then pulled directly out.
' What I claim is 1'.' In a furnace wall, a plurality of vertical beams, a plurality of horizontal rails mounted on said beams, a plurality of brackets ea ch gravity supported on an upper rail and restrained to side toside movement by a lower rail, and means on each bracket for supporting a plurality, of tiles.
2; In a-furnace tile supporting structure, a plurality of parallel guides, a plurality of brackets, each resting upon one guide and positioned by an adjacent guide and free to move with respect to either guide.
3. In a furnace wall, .a plurality of horizontal suppofting members, a plurality of brackets movably supported by each member plurality of courses and rowsin alinement,
spaced brackets, each supporting and anchoring adjacent Vertical rows of, one section, staggered brackets each supporting and anchoring adjacent vertical rows of the section below, which latter rows support an unanchored vertical row of-the sectionabove, and means for supporting the brackets of one section and for positioning the brackets of a proximate section, each of said brackets being free to move with respect to either supporting means upon expansion. 5. In a furnace wall, a' plurality of sections each of a plurality of courses the tiles of which are in regular vertical and horizontal alinement but staggered with respect to the proximate upper and lower sections, a plurality of brackets each interlocked with two vertical rows of tiles of one section,'an= intermediate vertical row of tiles for holding each adjacent vertical row in such interlocking engagement with a bracket, and means for supporting said intermediate vertical row.
6. In a furnace wall, an outer wall, .an inner tile wall spaced therefrom guide means carried by the outer wall, supporting means for the tiles of the inner wall slidably mounted upon said guide means and restrained thereby from front to back movement while having freedom to move up and down and side to side with the expansion and contraction of the wall. 7
7 The wall of claim 6 in which some of the tiles of the inner wall engage the rear wall.
8. ln a sectionalwsupported inner furnace wall, a shelf extending horizontally between adjacent courses of tiles, and means for re- 1 angle iron with freedom for side to side movement, a shelf extending forwardly from each bracket, and tiles resting upon each shelf and in interlocking engagement with the flanges of the proximate bracket.
In testimony whereof I affix my signature.
PETER MoKENZIE.
