INTERLOCKING TILE;

Application filed October 31, 1921.

I T 0 all whom it. may concern Be it known that I, F iANK DOCHNAL, a citizen of the United `States, and resident of Collinsville, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Interlocking Tile, of which the following is a specification. My invention relates to certain new and novel improvements in tile for wall structures, such for instance as factory stacks, that can be interlocked by means of a cementitious, or concrete material, and, is a distinct and practicalv improvement to overcome certain important practical objections to, and defects in, the tile now used in above structures, and, has for an object to provide ap improved form of tile having its inner face provided with a plurality of spaced parallel facial ribs, or webs forming in top plan view, irregular longitudinal channels therebetween to provide anchor pockets. y a

A further obj ect of the invention is to provide the tile with a central facial rib, or web and a pair of side ribs, the latter lying below the plane of the central rib, or web. j Other objects and advantages of the herein described invention will be hereinafter referred to and more particularly pointed out in the claims hereto appended.I

Referring' to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

'Fig. 1, is a perspectiveview of -a radial tileconstructed in accordance with my invention.

Fig. 2, illustrates the use of t-he tile in a stack structure, portion shown in `section taken on line 22 of Fig. 4.

Fig. 3, is a detail showing the tile as laid in a wide circular wall structure.

Fig. 4, is a detail showing the tile as laid in a narrow circular wall structure as in finishing off stacks.

Referring to Fig. 1, of the drawingsfthe tile consists of a body 1 having a plurality of verticaly passages 2. Each end face of the tile is provided with a verticalchannel 3 to provide the spaced parallel end facial ribs, or webs-4. The inner face of the tile is provided with a pair of suitably shaped facial ribs, or webs 5, preferably keystone in shape, which are positioned near each end of the tile, as clearly shown in Fig. 1. The inner Specification of Letters Patent. I' Patentgd Aug, S, 19122.

serial No. 511,920,

face of the tile is also provided with a con* verging body 6 terminating in a suitable, preferably keystone, shape central facial rib, or web 7 the plane of which lies in advance, or inward a considerable distance of the plane of each of the facial ribs, or webs 5, f

as clearly shown in Fig. 1.

The inner face of the tile is provided with a recess 8 between each facial rib, or web 4, and the converging central body 6 of the tile, thus helping form an irregular anchor pocket 9 on each side of the converging body 6 of the tile and to deepen the same, as shown.

When two tile are laid end for end, it will be observed that a suitable, preferably keystone shaped anchor pocket 10 is formed between the facial ribs, or webs 5 of the adjacent tile, which in a wide wall structure is merely filled with cementitious material, and, in a narrow wall structure receives the central facial rib, or web 7 of an opposite tile as well as the cementitious anchor, or binding material. 11, as clearly shown in Figs. 3 and 4.

lVhether the wall be wide or narrow, the inner face of botl. the inner and outer wall tile being provided with irregular shaped anchor pockets 9, tends to form an irregular circumferential anchor pass-age between the tile walls, which, when filled with cementitious material, forms interlocking anchors for holding the tile from displacement.t

VVhen vertical reinforcing rods 12 are employed in the narrow wall structures, the rods find lodgment in the pockets 9, as shown in Fig. 4.

The vertical end channels?) of the tile form between the ends of two adjacent tile laid end for end, an anchor pocket 13 to receive the cementitious material 11, and, these pockets 13 connect with the pockets 10 through the bonding space 14.

When the wall structure is narrow, it will be observed that the central facial ribs, or webs 7 of the outer wall tile are received in the pockets 10 formed between the ribs, or webs 4 and 5 of two adjacent tile laid end for end, and, that the central facial ribs, or webs 7 of the inner wall tile are receivable in the pockets 10 formed between facial end ribs, or webs 4 and 5 of two adjacent tile laid end for end, as clearly shown in Fig. 4. It will also be evident that when the tile are laid in rows in break joint relation. the ribs, or webs 7 of the outer wall tile of one struction shown and described, but desire tok have it understood that the invention I have shown in the drawings is merely illustrative, as it is'manifest that various minor changes may be made in the exact construction and particular arrangement of parts without departing from the spirit of my invention, hence I reserve the right to make 'an'` such changes, or modifications as may fair y fall within the scope of the appended claims when fairly construed. A

Vhat I claim is:

l. A tile for factory stacks comprising'a perforated body, spaced vertically disposed ribs at the ends thereof to form end anchor pockets, spaced vertically disposed facial ribs extending from the inner face of the perforated body and one of said ribs eX-' tendingbeyond the plane of the other ribs.

2. A tile comprising a body, a plurality of spaced facial ribs directed from the inner face ofthe tile bodyjand one of said ribs being disposed midway the ends of the tile body and extending beyondlthe plane of the other ribs. O

3. An interlocking tile comprising a perforated body havin its inner face provided with three facial ri s, the intermediate rib extending beyond the plane of the other two ribs.

In testimony whereof, I have hereunto signed my name to the specification.

l FRANK DOCHN AL.
