TILE.

Specification of Letters Patent. v Patented Apr, 18,1911.

Application filed March 81, 1909. Serial No. 1=8'i,063.-

To all whom 'it may concern:

Be it known that I, ERNEST F. Winona- HoLur', a citizen of the United States, reslding at St. Louis, Missouri, have invented'a certain new and. useful Im rovement in= Tiles, of which the following is a full, clear,

and exact description, such fas .will enable others skilled in the art to Which tains to make and use the/same, reference being had to the accompanying drawings, forming part of this'speification, in which- Figure 1 is a perspective view of a tile of.

my improved construction, showing the same to provide atile having two mainwalls withv as it appears before the temporary webs are removed; Fig. 2 is a plan view of my improved tile with the temporary webs broken.

away; 'Fig. 3 is a plan view of a tile having a modified form of removable webs.

My invention relates to a new and improved tile particularly adapted for use, in the building of walls, chimneys and like structures, the object of my invention being temporary .webs which are so disposed as to hold the ends of the walls in proper position when the tile is first formed and during the drying and burning operations, and which temporary webs or removable sections are broken out when the tile is ready for use.

To theabove purposes, my invention consists in certain. novel features of construc- 7 tion hereinafter more fully described and tamer, or. for a chimney.

vide lateral communication between the spaces on the opposite sides of said wall '2,

spaces are usually filled with self-. hardening plastic material;

which When my"1mproved tile is formed, the outer portions of the arallel walls 1 are united by transversely disposed webs 4, and formed on the inner faces of said Webs 4 adjacent their ends are grooves 5 preferably V-shaped, said grooves it apperbeing of such depth as that they extend approximately halfway through the thickness of said webs. Formed in the-outer faces of the webs 4 directly .op- 'posite theqgroovesb are shallow grooves 5, and thus weakened lines are formed adjacent the ends of the webs 4 for'the' purpose of readily breaking away the central ortions of said webs when the tile is Formed in the outer face of the removablesection of each web 4 1s a pair of vertically disposed grooves 6 preferably V-shaped in cross-section, and formed on the inner face of this removable'se'ction immediately opposite the grooves 6 are shallow. grooves 6 thus forming weakened lines on Whichthe removable section may readily break when removed The inner faces of walls 1 and both inner and-outer faces'of the endsections of the webs '4 are scratched or scored to provide nished.

roughened surfaces which materially assist in anchoring the filling of concrete or cement which occupies the tile when the same is pos sitioned for use.

Tiles of my improved construction are usually formed of clay'or analogous material, the' same being in a plastic. condition, and therefore said tiles are comparatively soft when first produced, and by providing the webs 4 betweenthe ends of the walls 1 ,the shape of the tile will be maintained while the same is soft and whilerit is being dried and burned, and said tile will readily withstand therough usage to which it is subjected during the handling inthe drying kiln and furnace. The tiles so formed are delivered to the builder with the Webs 4 intact and when the tiles are to beaised in the building of*'a wall, chimney, or the" like, the outer faces of the central sections of the webs 4 are struck with a hammer or like tool and said central sections will break away along the weakened line's formed bythe grooves 6 and 6, and the side vportion of-said eentral sections will break away fromthe e'nd portions of the webs-4 along the weakened lines formed by the grooves 5 and 5*, this breakage being illustrated at the right in Fig. 2. Thus the entire cen;

tral portions of the webs 4 are removed an the end portions of said webs 4 formyertically disposed flanges on the inner faces ofthe wall 1 which flangesmaterially assist in rial which occupies the tile.

the anchoring of the. filling of plastic mate: 110.

shage While I prefer to provide a pair of grooves 6 in the outer face of each removable se ction of the webs 4, it will be understood that said removable section may be provided with only one groove as shown in 3, and where such construction is utilized the removable section will break into two parts. v I

The grooves 5. and 46 are made V-shaped in cross-section in order to provide sufficient clearance space between the corners of the removable sections when the sameswing or move inwardly when broken away, "thus doing awa with the danger of breaking the wall 1 o the tile and thereby rendering same unfit for use. Thus it will be seen how I have provided a tile with strengthening webs which maintain said tile in proper, during the time the same is in a soft con ition and while the tile is being dried and burned, and portions of which webs are readily removed prior to the setting or 10- cation of the tile in a wall or like structure.

It is essential that the V-shaped grooves extend at least half-way through the thickness of the webs 4 in order that the removable sections of said webs will readily break away without any wedging action or any a groove formed in the outer face of each of the pair ofwebs all of which grooves extend half way through the webs to 'permit t e portions of the webs between said gr oves to be removed without exerting pressure on the end portions of the walls of the tile.

2. The herein-described tile comprising a pair-of walls, webs connecting the ends of said walls there being grooves formed in the inner faces of said webs which grooves are arranged adjacent the walls of the tile, there being a groove formed in the outer face of each web which last mentioned groove is arranged between the grooves on the inner face of said web all of which grooves extend half way through the webs there being shallow grooves formed in the faces of the webs directly opposite the first mentioned grooves, and a web connecting the central portions of the walls.

3. The herein-described tile comprising :1

- pair of walls, webs connecting the end portions of said walls there being grooves formed in both faces of each web which grooves extend over half-way through the webs in order that portions of said webs between the grooves may be removed without.

exerting outward pressure on the end portions of the walls, and a web connecting the central portions of the walls.

In testimony whereof I hereunto ailix my signature in the presence of two witnesses, this 29th day of March 1909.
