CONCRETE TILE.

Application filed July 3,1922. A Serial No. 572,863.-

This invention relates to a new and iniproved concrete tile, and more particularly to a tile which may be made in large quant itie's with a small expenditure of labor and with relatively small space requirements for the manufacture.

in the making of concrete tile as here-' tofore practiced, it has generally been considered necessary to have a relatively large lay-out in order to provide large space for pouring the tile and permitting them to sufficiently set before removal from the forms. The tile have normally requ red to remain in the forms such a length of time as to require an excessive number of forms in order to producetiles on. a commercial scale. v

Concrete tile, as now generally con-r st'ructed, are susceptible of breakage unless carefully handled and placed and are, moreover, difiicult to secure and mantain in place.

Also such tile do not in themselves afford a water-tight roof but require thelaying of a water tight roofing as a separate prelimi-' nary step before the laying of the tile.

. It is an object in this'invention to provide tile. the combination providing a watertight and wind-tight roof.

Other and further objects will appear as the description proceeds. a 'Broadl my tile comprises a body portion, a po tion of which is specially'formed for properv bearing contact upon the roof upon which it is to be placed. It is further provided with adequate bearing surfaces for contact with adjacent tile both above and below. In the method of construction, the

tile are made in gang molds comprising a plurality of molds placed together, the mold members also preferably serving as pallets for handling the tile. In the preferred method of construction,- heat is applied ex ternally to the molds to expedite the set of the concrete.

4 I have illustrated certain preferred em bodiments of myinvention in' the accompanying drawings, in which I Figure 1 is a fragmentary section-showing tile in place upon a roof;

Figure 2 is a plan view, partly broken away, of a tile; w

Figure 3 is an edge view partly broken away, of a tile; and

Figure 4 is an end view of a tile.

As best shown in Figure 1, the tile oom- "prises a body portion 11 having at one edge an upwardly extending portion 12. This portion 12 is adapted to receive clips 13 which clips are secured to the roof and serve to hol the tile in place. That part of the body portion located below and adjacent the upwardly extending portion 12 is chamfered to provide a bearing surface 14 adapted to rest upon the roof 16. The chamfered porto permit the passage of moisture along the roof surface. As shown, the roof 16 is placed over the wood shingle roof 17 which it here serves to replace. I Thelower end of the tile is provided with the downwardly extending portion 18 adapted to overhang'the-upwardly extending bearing portion ofthe juxtaposed tile.

The under face of the tile is provided with spaced. recesses 22 adapted to receive that portion of the cli 13-which extends over the portion 12 o the adjacent tile." The recess is considerably wider than the clip sotha-t the successive rows of tile need not be in exact registration.

7 tion 14 is provided with grooves 15 adapted Each tile 11 is of such length as to corre- 'spond to a number of tile or shingle of normal width. The tile ismarked with a plurality, of equally spaced transverse grooves 19 upon its'upper surface and lower .edge, these grooves servingto render the singletile similar in eneral appearance to av plurality of tiles. e tiles are preferablyre-inforced by wires 20. and 21 which add materially to their strength. The tile may become cracked at the grooves 19 or may be intentionally crackedto allow forinequalities in the supporting roof. In such cases the wires 20 and 21-hold the sections together.

. While anyusual sheathing or paper may be, used below my tile; I preferably use strips of roofingrpaper in the manner shown in Fi re 1. e strips-of paper v23 are sligh y wider than two'rows of tile. The

upper edge of a strip is secured under the clips 13 atthe upper v The strip lies flat on the roof for the width of this row of tile and extends under the clips 13 of the next lower row of tiles. It then extends against the lower face of this latter row of tiles and its lower edge rests on the upturned porti0n12 of a third row of tile. The lower edge of the strip thus serves as a cushionedbearingl between adjacent, rows of tile.

No additional securing means are needed for these strips which are held in place by the tile clips. Should any water blow up in under the edge of a strip, it will fall upon the next lower strip and run down through grooves 15 below the next lower shingle and out on to the roof again.

I have shown one preferred form of my invention by way of example, but it is to be understood that I contemplate such edge of a row of tile.

changes and modifications ascome within the spirit and scope of the appended claims.

I claim:

1. A tile or the like having a body portion, the body portion adjacent one edge thereof being chamfered to fit upon a supporting surface with the body of the tile in angular relation to the surface, and grooves for the passage of moisture extending through said chamfered bearing ortion;

2. A tile or the like having a Eody portion, the body at one end being provided with anupwardly extending portion adapted to act as a-bearmg for. a superposed tile, and a recess in the lower face of the tile adjacent the opposite end adapted to' provide clearance for tile securing means engaging the bearing portion of alower tile.
