STILE.

SPECIFICATION formrng part "of Letters Patent No. 573,939, dated December 29,1896. .pplcation filed January 4,1896. Serial No. 574,376. (No model.)

Be it known that I,WILLIAM ARTHUR CAM- ERON WALLER, gentleman, a subject ofthe Queen of Great Britain and Ireland, residing at 6 Kyverdale Road, Stoke Newington, Lon-` don, England, have invented certain new and useful Improvements in the Construction of Tiles, of which the following isa specification.

This invention relates to an improved construction of tiles for roofing purposes, and has for its object to provide tiles which will lock themselves in position in a simple and efficient manner.

In carrying out my invention I form the tile with a number of projecting surfaces on both faces, the surfaces being of special shape and adapted when the tiles are fixed in posi` consisting of a rib at the edge extending from the upper corner for an equal distance at each side and two projections close to the side corners. Three projections are formed on the under surface, adapted to lit between the projections on the upper side of the adjacent tile, so that the two will interlock.

In order that the water may be prevented from penetrating between the tiles, a drip arrangement is employed, consisting of a small V- shaped or other suitably-formed channel in the projecting surfaces. These channels or gutters lead from the upper ends of the projecting faces to the lower extremities, and any water which may gather will run down these gutters, which will also prevent capillary attraction.

In order that the invention may be more clearly understood, reference is had to the accompanying sheet of drawings, in which- Figure l is a plan of a tile according to my invention. Fig. 2-is a side view, and Fig. 3 a section, of the same. Fig. 4. is a plan showing the tiles connected together. Fig. 5 is a section of the same.

Fig. 6 is a detail view of the gutteror drip, andFigs. 7 and S show slight modifications. i j

Referring to Figs. 1 to G, A is the tile, shown of diamond shape, with the corners a cut off. The arrangement is such that when the tiles are placed in position these corners ct abut against each other in each of the parallel rows, as shown in Fig. 4, portions of thetiles being broken away in that figure to illustrate the arrangement more clearly. On the upper surface of the tile, at the top, the V-shaped ledge or 4projection B is formed, extending along the edge for a short distance. Below this ledge the projectionsl B are formed, a gap being left between the surfaces. The extremities of B and B are preferably made parallel. The edge h is formed at an angle to the cut-off end a, so that when the tiles are placed together, as shown in Fig. el, a wedgeshaped gap will be` formed by the adjacent edges l). On the under surface three ledges are also employed, the bottom one, C, engaging between the projections B on the two tiles immediately below.

The tiles are placed alternately, so that the lower points of each row project over the ends a of the row immediately below, forming a diamond pattern. The ledges C extend along the bottom of the tile to the ends a, gaps be ing left between C and C', which receive the projections B' on the adjacent tiles. The een tral portions c of the ledges C exactly fill the gaps between B and B. The ledges thus engage with B and B', the tiles overlapping sufficiently far to allow of this.

D is the gutter or drip-groove formed in all the ledges and illustrated in detail in Fig. G. As shown, it extends parallel with the edges of the tile andguides any water that may collect to a suitable point, from which it can es cape without penetrating below the surface of the tiles.

In order to secure the tiles to the battens E, (shown in Fig. 5,) ribs or projections e are employed extending from the under surface at the center. These ribs are sufciently deep to clear the tile immediately belowthe one on which they are formed, as the tile overlaps the one below for a short distance above its center, and allowance must therefore be made for the thickness of a tile. -The battens E IOO thus lie between the two ribs e, which are placed horizontally.

Fig. 7 shows an arrangement in which the tiles A have their lower edges ce' curved, so as to give a more attractive or ornamental appearance to the tile, the arrangement otherwise remaining the same. The lower portions of the tiles may be made semicircular or of any other curve found suitable. According to Fig. S the tiles A2 are of somewhat elongated form and the lower corners CL2 are cut off.

B' extending along the upper-sides, and separated from ledge B, of an angle-led ge C on the other side and at the bottom, and two side ridges C adapted to engage with and between the ledges B I3 of adjacent tiles substantially as described and shown in the accompanying drawings and for the purposes speciiied.

2. In an improved tile the combination with the V-s'haped ledge B at the upper end, the side ridges B separated from the projection B the angle-ledge C on the lower side of the tile and the side ledges C', of the drip-groove D formed in the said ledge, and extending parallel to the sides of the tile substantially as described and shown in the accompanying drawings7 and for the purposesspecied.

In witness whereof I have sworn to and set my hand in the presence of two witnesses.

WILLIAM ARTHUR CAMERON WALLER.

In presence of- ALBERT EDWARD ELLEN, HENRY ALFRED WooDBRIDGE.
