FLOOR TILE Filed June 30, 1950 2 Sheets-Sheet 2 NVENTOR ATTORNEY vPatented ct. 20, 1931 PATENT oFFlcE (3H-ARLES WILLJIAM A KEBS, 0F NASHV'ILIE, TENNESSEE FLOOR TILE Application led June 30,

rIhis invention relates to an improved construction of hollow tiles used in the construction of iioors, the general object of the invention being to provide means for strengthening a ioor formed of concrete and to facilitate the construction of the Hoor.

Another object of the invention is to p-rov 1@ provide means on the tiles which will facilitate the leveling of the concrete as such means on the tiles form guides or screeds for the leveling members.-

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated ly pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a sectional view showing how the tiles are used in the construction of a concrete lioor. 1

Figure 2 is a view of one of the tiles shown in use in Figure 1.

Figure 3 is a sectional view of a floor, showing the use of modified forms of tiles.

Figure 4 is a view of one of the tiles shown in use in Figure 3.

Figure 5 is a view similar to Figure 3, but

showing the use of another form of tile.

Figure 6 is a view of the tile shown in use in Figure 5. l

Figure 7 is a view similar to Figure 5, but showing the use of still another form of tile.

Figure 8 is a view of one of the tiles shown in use in lFigure 7.

Figure 9 1s a sectional view through a tile provided with two cores. p

In that form of the invention shown in Figures 1 and 2, the tile 1 is formed with a fiat bottom, tapered side edges and a fiat top which is formed with a longitudinal rib 2. The tile is formed of reproof material and is of such anature that a nail or the like can be driven into the same. In use, the tiles are 4REISSUED f 1930. Serial No. 464,989.

set on the strips 3 supported by the upright frame 4, the strips 3 forming portions of the floor mold and in order to evenly space the tiles apart in the rows, I provlde a spacer strip v5 .which is placed on the strip 3 against the row of tiles which has already been laid so that another row of tiles can be placed against the strip 5, as shown in Figure 1.l The strip 5 is then removed and the concrete 6 is poured on the tiles and between the spaces between the rows of tiles after the reinforcing rods 7 are put in place. The rods 2 form guides or screeds for the leveling board which is used to level the concrete after the same has been put in place. When the concrete hardens, the concrete and the tiles form a floor or horizontal partition and when a flooring 8 of wood or the like is to be laid on the concrete floor, this iooring can be nailed to the ribs 2 on which it rests, as shown in Figure l.

Figures 3 and fl show a tile 1 which is formed without the rib 2 and this tile is also formed with the iianges 9 at the lower parts of its sides. The flanges of one tile will abut those of another, as shown in Figure 3 so that these tiles are selispacing and the use of the spacer strip 5 is not necessary. With the use of the tiles shown in Figures 3 and 4,

the entire ceiling is formed bythe base arts.

ormsthese tiles are separated the same as the tiles shown in Figures 1 and 2.

Figures 7 and 8 show a tile 1Il which is provided with both the rib 2 and the angs 9 so that this tile combines the features of the tiles shown in Figures l and 2 and 3 and 4. Figure 9 shows how the tiles ma be formed with two cores 10 instead of a single core, as in the other iigures. Of course, the tile can be formed of any internal shape, as desired. n p

The improved tiles facilitate the laying of concrete floors, as the tiles form portion of the forms for receiving the, concrete and a. solid 'bottom fora form is not necessary, as

it is simply necessary to provide means for supporting the tiles and when the tiles are spaced apart as in Figure 1, the members 3 are simply used to close the bottom of the spaces between the rows of tiles. When the tiles having the ribs thereon-are used, the ribs form iding means for the leveling board and a so as supports forflooring or the like which can be nailed to the ribs. The

-exposed baseA ortions of the tiles can also have ceiling or-ming :meansor any other means attached thereto by nails or the like. The tiles may be formed of cinder concrete or any other suitable'material which will permit nails or the liketo be driven' into the tiles. The ceiling formed by the flanged tiles shown in Figures 3 and 7, may be painted,

lasteredor otherwise treated, or the ceiling ormingfx'nevtal, boards or -the like may be fastened "to' the tiles.-

4. A tile for concrete floor construction having a rib extending across one face thereof adapted to project through a body of concrete placed over said face, and means for positioning a reinforce element extending transversely of said rib in spaced relation with respect to both the projecting surface of said rib and the said surface of said tile.

In testimony whereof I alix my signature.

CHARLES WILLIAM AKERS.

One end'gof the rib'of eachl tile may be y beveled, as shown at 11,'these beveled parts forming spaces for reinforcing rods or bars 12 placed adjacent the surface of the concrete and which act to prevent surface cracks. In forming this recess 11 in the rib, whether it be at the end thereof or not, the recess should not extend to the top face of the tile. The depth, however, will depend on the height of the rib, the depth of the recess preferably being such that reinforce elements placed in the recesses will be positioned adjacent the surface of the concrete, as just mentioned.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A tile for a concrete floor structure having an integral elongated centrall arranged rib, extending longitudinally of the top surface of the tile throughout the major portion of the length of the tile, said rib being formed of nailable material and adapted to project through the floor structure, one end of the rib being reduced to form a space for a reinforcing bar.

2. A tile for concrete floor construction havin an elongated rib of nailable material exten ing substantially entirely across one face thereof, a portion of said rib being removed to form a transverse depression therein for the lacement of a reinforce element.

3. A ti e for concrete floor constructionl havin a rib across one face thereof, a portion o said rib being removed to form a transverse depression for the placement of a reinforce element, the depth of said depression being less than the height of the rib to position the reinforce element adjacent the top ment to hub flanges.
