TIMOTHY LYnoN, or BALTIMORE, MARYLAND.

WALL AND CEILING STRUCTURE.

Application ed January 19, 1922. lSerial No. 530,325.

To all whom t may concern:

Be it known that TIMOTHY LYDON, a citizen of the United States, residing at Baltimore, in the State of Maryland, has invented certain new and useful Improvements in Wall and Ceiling Structures, of which the following is a specification.

This invention relates to improved means for securing tiles, slabs or plates in place in l0 the formation of ceilings or walls.

The term tiles as herein employed by me is used in a broad sense in that it is applied by me to any wall or ceiling element which is molded or shaped into a tile, slab or plate and is not necessarily a baked product.

The object of the invention is to provide improved means whereby tiles, slabs or plates may readily be secured to overhead joists to form a ceiling or to studding in the formation of a walk-the structure being such that unskilled labor may be employed and the tiles readily applied regardless of the irregularity in the spacing of the joists or studding.

With the above and other objects in view the invention is illustrated in the accompanying drawings, wherein,"

Fig. 1. shows a sectional perspective view of a series of joists with iiooring on the upper side and with my improved tile securing devices on the lower side thereof.

Fig. 2. illustrates a cross-sectional view of the same,-the section being taken on the line 2-2 of Fig. 1 to which the facing slabs have been added.

Fig. 3. shows, in perspective, a series of tile supporting stripsr and tiles` sustained thereby as viewed from the upper side,.- the joists above being omitted.

Fig. 4. illustrates a side edge view of a plulrality of tiles to show how they lap.

Fig. 5. shows an enlarged detail of one of the tile supporting strips with a tile at each side thereof and also shows the means for securing the strips in place.

Fig. 6. illustrates one of the detached tile-supporting strips.

Fig. 7 shows one of the tiles in perspective.

Fig. `8. illustrates a sectional detail through the tile, in a lengthwise direction or from end to end, and

Fig. 9. shows a cross-sectional detail through thetile from one side edge to the other.

Referring to the drawings the numeral 12, designates a series of spaced-apart supports such as joists or, in the case of a wall, a series of studs which in practice are presumably spaced at equal distances apart, but in reality are frequently spaced unequally. In some instances the unequal spacing between the centers of the joists or studs is so pronounced that it is impracticableto attach tiles, slabs or plates directly to those joists or studs, but in accordance with my inven tion it isimmaterial whether the joists or studs be equally or unequally spaced.

In carrying out my invention I ,employ what I term a series of supporting strips or rails 13. These strips or rails as best shown inF ig. 6 of the drawings have fiat parallel inner and outer faces 14: and 15 respectively,-the outer face being wider than said inner face so as to form longitudinal side anp'es 16 at opposite sides of each strip.

The supporting strips ory rails 13, are seated with their innerI narrower faces 14: against the joists or studs and extend at right angles to the latter so that each strip will extend across a series of joists or studs, as clearly shown in Fig. 1 of the drawing.

These strips or rails 13 are equally spaced and are rigidly secured to the joists or studs they cross by means of nails or equivalent fastenings 17, as shown in Fig. 5 of the drawings. Y

In some instances I have found it desirable to lay a brace strip 18, againsty the outer wider face 15 of each rail 13 and have the fastening 17 extend through the latter, then through the rail and onto the joist or stud 12. This brace plate by extending across the outer wider face of the rail serves to support the rail at the opposite edges where the side fianges 16 are located, which is very de sirable as will presently be seen.

In the case of a ceiling structure the upper side of the joists will sustain the flooring 19 as shown in Figs. 1 and 2.

In carrying out my invention I utilize a special construction of tile, slab or plate, 20, a form of which is shown in Figs. 7-8 and 9 of the drawings to which attention is now directed.

' For the sake of brevity I shall hereinafter make use of the single expression slab, which however is to be construed as meaning a comparatively thin tile, slab or plate.

- 1 the outer surface 22. At the opposite end,

the slab has a flange 25, which is flush with the outer surface 22 and which projects beyond the inner surface 21.

By reference to Figs. 7-8 and 9 it will be noted that the flanges 23-2e and 25 are each half the thickness of the slab so that if an underlapping flange 25 on one end of a slab is fitted against an overlapping flange 24 on the end of another slab the two lapped flanges will together substantially equal the thickness of a slab.

By refer-ring to Figs. 8 and 9 it will be noted that each slab has a plurality of wire strands 26 extending crosswise therethrough and that the opposite ends of the wire strands project along the under faces of the side flanges 237 all for a purpose presently to be explained. Y

TheY supporting rails or strips 13 are so spaced with respect to each other that a slab 2O may be placed between them with the side flanges 23 of the slab lapping the sideflanges 16.0f the rails, as clearly shown vin Eigs. 3 and of the drawings.

ln the ease of a ceiling structure the flanges 23l of the slab will seat in the flanges 16. of the rails at opposite sides of it and thuslsustain the slab between the two rails.

lt will also be noted thaty as the ends of theY cross-wires 26 project along the under side of the slab flanges 23 that they will reinforce those flanges at the point of suspension.

As the weight of the slabs is directly on the. rail flanges 16 any tendency of those flanges to split or break olf is overcome by thefbrace strip 18.

By reference to Fig. 5 it will be noted that when the slabs arev seated on the rail flanges 16 their inner faces 21 `will be slightly spacedfrorn the lower facesof the iinish,-this however being immaterial to my invention.

'llhen the slabs are in place their ends will be engaged by the end flange 2e of one lapping the end flange of the next so that an end support will thus be provided between the ends of abuttingslabs.

l-lavingdescribed iny inventiom claim,

1. In a wall or ceiling structure the coinbination with spaced apart supports of parallel but spaced-apart flanged rails extending at right angles to and crossing said supports said rails being rigidly secured against the said supports, separate slabs each having overhangingside `flanges at two opposite sides vand each slab also-having at one end a flange that is flush with the inner surface 0f theslab while at the opposite end each slab has another flange which is flush withl the outer surface of the slab whereby to produce an underlapping flange at one endV and an overlapping flange Vat the opposite end of said slab,-the slabs being supported their sideV Yflanges on the lflangesof the rails and one end of a slab underlapping the slab next t0 it at that end while the opposite end vof the saine slab willoverlap the slab next to it said llatter end Yand the adjacent .ends of two slabs /thereby be brought into direct butting and lapping contact one with the other.

2. The combination with spaced apart supporting ineans7 of flanged rails secured to said supporting means and extending crosswise of the latterfseparate slabs each having side'flanges whichengage and arev sustained by the rail-flanges and said slabs also having an underlapping flange at one end and an overlappingflange at the opposite end wherebyv the adj acent ends of the several slabs may be lapped and supported at the. end one by the other.

In testimony whereof l affix` iny signature.
