Application ii1ed Ann 14,

This invention relates primarily to tiles and tile arches employed int'he construction of tunnel kilns, but is not limited in its application to such use; Among the objects oi our invention are; to provide new and improved tile for the construction or tile arches; to provide a new construction of tile arch to provide improved ine'a'ns forperinitting enpai'ision and contraction of the tiles in tile arches, without placing strain on the tiles; and such turtl'i'er objects advantages and capabilities as will later more fully appear. A

Gu invention further resides in the coinbination, construction and a-rrai'igenie'nt of parts illustrated in the accoinpa'i' y'ing drawings and while we haveshown therein preferred en'ibodinients we desire the same to be understood as ilhistrative only and not as limiting our invention.

in the accompanying drawil'igs, Fig. l is an end view of one torin at tile eniboc'lying our present invention; Figs. 2 8 and 4 are cross sections of tile arches constructe'd ii-i accordance with our present invention; Fig. is an 15011165110 cross section of a tile arch supported by structural steel; Fig. 6 is an isometric View of a tile such as that shown in Fig. 1, and 7 is a fragmentary section showing a modified form of tile having spacing ridges, lugs, 01' the like, on the projecting flanges, to cause spacing of the tiles and reduce friction tending to prevent the tiles from sliding with respect to one another when heated.

Referring more in detail to the annexed drawings, numerals 1, 2, 3 and 4 designate tour ditlerent tiles embraced in our invention, those shown in Figs. 1 6 and 7 being hollow, while those shown in Figs. 2; 3, 1 and 5 are solid. It will be obvious from Figs. 1 6 and 7 that the hollow tiles may be formed with longitudinal apertures of any desired shape, such as circular, square or oblong in cross section, but. as shown in these figures, it is preferable that there be a central aperture 5, extending substantially across the tiles. Between the ends of this aperture 5 and the side walls of the tile are slits 6 which weaken these walls of the tile so that it can be readily broken in two by being suitably struck. This will result in the formation of half tiles, which may be used in the same manner as tiles 3 in Figures 2 to 5; The tiles t are formed in subserjiai no; 4613469;

lly the same manner is the titles 1, are provided at certain edges with Y es, Inge, or the like, 7. These result in the production of air spaces l'JetWeen the tiles wlie'ii' they are built into a construction as shown in F T. suit in th'edecrcase in the amount of friction between engaging spaces and therefore make it easier for them to slide on each other when the tile arch isheated during use. Vith the constructions shown in F 1 2, this result is in part accomplished in a (litter-silt manner, that is, by inserting betw en the tiles, at the points marked 8 strips pl or the like. Wlren the kiln is heate ese strips oit aper will burn out l'e" "e spaces between the tiles to z'rccoh'rni'oda'te the expansion due to heating oi the tiles I The various forms of construction an: the tile arch will next be desc 'ibed. Fig. 2 shows the construction of a tile arch C0111- prisin'g whole tiles 2 and half tiles 3 supported by concrete 9 having ei'n'bedded therein reii'i' torci'n'g rods 10'. It will be obvious that when this construction has' been erected and has become thoroughly set, if a fire is started and the kiln is heated to a high tentperfre, the paper or the like at 8 will be burned out and. will leave a slight space at these pointstoi the necessary relative inoveinent caused the expansion and contra-cti'o'n oi the tiles when heating up and cooling d r'iw'n'. v

The construction of Fig. 3 is siinilar to that of Fig. 2 but has supporting I-beanis, portions of which are embedded in the concrete 9. Connecting the I-beams 11 are tie rods 12 which are embedded in the concrete 9 and hold the I-beanis in position. This figure also shows the use of an ext layer of tiles 2 to increase the thickness of the kiln structure.

In Fig. 1 a plurality of reinforced concrete girders take the place of the I-beams 11 shown in Fig. 3 and these are stayed by cross beams 14 which take the places of the tie-rods 12 of Fig. 3. It will be noticed that in this figure the thickness of the tiling is midway between the thicknesses shown in Figs. 2 and 3. The til-es 2 and 3, the paper strips in spaces 8, the concrete 9 and the reinforcing rods 10 are the same in this figure as in the preceding figures.

In Fig. 5, I-beams 11 support channel irons These projections also re- Ms will be sup- 0 second named and held braced so 111.1%" th M 1011. n. \JIZHUN. PY (E. LYVKETT.
