BUILDING SLAB UR TILE.

Specification of Letters Patent.

Patented May 31, 1921.,

Application led July 15,1918. Serial No. 244,891.

To all whom t may concern.'

Be it known that I, TIMOTHY LYDON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful mprovements in Building Slabs or Tiles, of which the following is a specification.

This invention relates to improvements in building slabs or tilesand has particular reference to a slab or tile that is especially designed for use as a ceiling or partition unit.

The object of the invention is to construct a comparatively thin tile, in such a way as to provide a lapping of one, slab or tile with the slab or tile next to it and to provide the same with improved means whereby to aid in securing the slabs or tiles in place.

The invention is illustrated inthe accompanying drawing wherein,-

Figure 1, shows the improved tile or slab in side View and looking at the inner or concealed' side thereof:

Fig. 2, illustrates an edge view of the same. j

Fig. 3, showsa slightly enlarged crosssectional detail through the slab or tile, and

Fig. 4, illustrates the slab or tile in perspective, as viewed from the inner or concealed side thereof.

Referring to the drawing, the numeral 5, designates the exposed or outer face side of the slab -or tile and 6, the inner or concealed side thereof. In some instances, where the slab or tile is to be employed as a ceiling structure I may provide the outer or exposed side thereof with cavities or ornamentation 7, indicated inthe sectional view of Fig. 3, but this is immaterial to the invention.

The precise outline of the 'slab orvtile is also immaterial although in the present 1nstance, the vsaine is shown as of a rectangular form.

In the form of slab or tile shown, the same has an outline that produces a plurality of straight sideedges, one extending at an an le with respect to the other.

eferring to Figs. 1 and 4, of the drawing, it will be" seen that the outer or. exposed face or side 5, of the slab has projecting edges 8 and 9, which extend' beyond adjacent edges 10 and 1'1, respectively of the inner face 6', of the slab. Tt will be further seen that the inner or concealed face 6, of

the slab has edges 12 and 13, which extend beyond adjacent edges 14 and 15, of the outer face 5, of the slab. This construction therefore provides a slab or tile with what might be termed overlapping projecting edges, such as the edges 8 and 9, at a plurality of adjacent sides, and underlapping projecting edges, such as the edges 12 and .13, at a plurality of other adjacent sides.

The overlapping edges and the underlapping edges each have a thickness, front to rear, of a uniform dimension, so that the thickness at each edge is substantially onehalf the thickness of the slab or tile.

This arrangement of overlapping and underlapping edges on the slab or tile-is such that when the tiles are arranged, one with respect to another, the overlapping outer edges 8 and 9, on one tile, will project over underlapping edges 12 and 13, of the vtiles next to it.

Each slab or tilehas its underlapping edges 12 and 13, provided with one or more notches 16, which extend inwardly from the` extreme edges, and are open at their outer sides,-the inner ends of these notches being flush with the edges 14 and 15, of the outer face of the slab or tile, as shown in Figs. 1, 3 and et of the drawing.

Each slab or tile is provided with one or more thin wires 17, which are embedded therein and which extend in a crosswise direction. One end of each wire 17, is provided with a loop or eye 18, which latter projects from the edges 1() and 11, and has position at the inner sides of the overlapping edges 8 and 9. By preference, the wires 17, extend entirely through the slab or'tile and have a free end 19, which rojects through the notches 16, at the under apping edges 12 and 13, of the slab or tile. These projecting wire-ends 19, may be utilized in instances to effect a securing of the slab or tile in place, particularly on the first tile of any row, as in the angle between a ceiling and wal It will be noted that the notches 16, at the underlappingedges of the tile or slab are directly op osite the loops or eyes 18, on the wire-en s so that when the tiles are set up the notch of the underlapping edge of one tile will straddle the eye or loop at the overlapping edge of another tile or slab and thereby permit the tiles to be set close together, edge to edge.

y Havingdescribed my invention, What l. A building slab or tile having, at a plurality of sides, edges Which project from the outer face and extend laterally beyond the inner face of the tile and also having, at a plurality of other sides, additional edges Which project from the inner face and extend laterally beyond the outer face of said tile, whereby to form overlapping and underlapping projecting edges at y diiferent sides of the tile and Said tile having a notch cut entirely through the edges Which project from the inner Jface and extend beyond the outer face and provided at the inner side .of the edges that project beyond the outer face/With a projecting loop .0r eye.

2. A building slab or tile having a front face with some connecting edges that project beyond somes edges of the rear face and also having a rear face' with some connecting edges that' project laterally beyond other edges of the front face,-the projecting rear-face edges havin notches and the projecting front face e ges being continuous and free of notches, and Wires embedded in each tile and extending through the same said wires being provided With an eye at one end that is located adjacent to continuous front faceedges and the other end of each Wire projecting from the tile at a notch Vin the projecting rear-face edges..

In testimony whereof I affix my si nature TIMOTHY LY ON.
