To all whom t may concern:

Be it known that I, CHARLES C. DAVIS, a citizen of the United States, residing at Germantown, Philadelphia, in the count of Philadelphia and State of Pennsylvania, ave invented certain new and useful Improvements in Reinforced Tiles or Slabs, of which the following is a specification.

My invention Arelates to improvements in reinforced concrete tiles or slabs; and it consists in the constructions, combinations, and arrangements herein described and claimed.

An object of my invention is to provide an improved concrete tile having an efficient reinforcing structure adapted to insure a maximum of stiffness and rigidity with a mini` mum of reinforcing material.

Afurther object of my invention is to provide an improved reinforced concrete tile having a substantially uniform stiffness throughout and in which loading strains will 'on the reinforcingconstruction.

A further object of vmy invention is-to provide reinforced concrete tiles constructed to be conveniently assembled and secured in osition to constitute a strong, durable, and

' impervious roofing.

In the accompanying drawings, forming a art of this application, and in which simiar reference-symbols indicate corresponding parts in the several views, Figure Lis a fragmentary sectional View illustrating a portion of a roof formed of my improved tiles. Fig. 2 is a side edge elevation, on a larger scale, of one of the tiles shown in Fig. 1.A Fig. 3 is a sectional view in the plane of the transverse retaining and strengthening bars ofthe reinforcing material, showing 011e tile 'and portions of two acent tiles; and Fig. 4 is a detail perspective view showing the common means for securing together the corrugated foraminated sheet, transverse retaining and strengthening bars, and the supporting-lugs.

.Re erring to the drawings, 1 indicates a sheet of foraminated material provided with longitudinal corrugations and which can be advantageously formed -of expanded'metal or of heavy woven mesh of iron or steel wire. At suitable distances along the sheet 1 transverse retaining and strengthening bars 2 extend freely through openings'in the side walls of the several corrugations of said sheet.

Supportin -lugs 3 for Securing the tiles in -their assemb ed' position on the building are shown, vcomprising angle-plates havlng one face lying ainst the end corrugations of the sheet 1. T e supporting-lugs are secured to the bars 2 by bolts 4, extendin through Said lugs and the end portions of sai bars. These bolts extend also through thel ortions of the between the y sheet 1 which are interpose supporting-lugs and thebars 2, thereby securmg the corrugated sheet 1 to the end' 'ortions of the retaining and strengtheningl ars y2. By thus securing the end corrugations of the sheetl 1 the l intermediate corrugations are permitted to adjust themselves uniform] along the retaining-bars 2, and strains ten I into atten any of the corrugations'are distri uted vto the several corrugations. This provides a very advantageous construction aving a maximum of stiffness with a Illinimum of reinforcing material and having'a.

substantially uniform stiffness throughout.4

The tiles 5 are formed of-,suitable material,-

preferably concrete, which is molded to pro vide beveled lips 6, extending from the sides thereof. One of the lips on each tile extends flush with the upper surface thereof.,l and the other lip extends flush with the lower surface thereof, said lower lip being formed somewhat longer than the upper lip in order toVV provide a channel 12 for the insertion ofY a suitable grouting or luting between the overlapping lips of-adjacent tiles, as shownl especially in Fig. 3.

Referring especially to Fig. 1 of the draw# ings, 8 indicates the usual angle-iron purlms,

to which the tiles are secure by bolts 9, ex-

.tending through the openings 10 in theirsup-Y The several tiers of tiles are porting-lugs. shown arranged with the lips of theadjacent.

tiles overlappingvandwith the lower tieroftiles formed to provide a continuous gutter 11."

I have illustrated and described a'preferred and' satisfactory construction; but

obviously 'changes could be made within the' spirit and scope of m invention.

Having thus descri ed my invention, Wlft.

I claim as nrw, and desire to securebyiet.- ters Patent, is-

1. A reinforced concrete tile, comprising a corrugated; sheetcffforaminated material,

retaining and strengthening bars extending through openings in the side Walls ofthe sev eral corrugations of said sheet, means for clamping saidsheet to the-end portionsqf` said bars, and a body of plastic material invcasing said sheet and retaining-bars, slibstantially as described.

, V2. A reinforced concrete tile, cornprisingiaA :orrugated slieetof foraminated material, re-

taining and strengtliiening` bars extending through openings in the walls 0f the several corrugations of said sheet, supporting-lugs `for securing said tile in position, a common v means for securing said lugs to the end por-- i. tions of said bars, and the adjacent portions of said corrugations, and a body of plastic -inaterial incasing said sheet and retainingbars, substantially as described.`

several corrugations of said sheetfsupport- I5 ing-lugs engaging the end corrugations of said sheet, a common means for fastening said supporting-'lugs to the end portions *,of said barsand for securing thereto the interposed portions of said corrugated sheet, and a body of plastic material incasing said sheet, andretainingbars, substantially as described. In testimony whereof I affix my signature in presence of two Witnesses.
