(CL 108 This invention relates to roofing tiles, and has face of the tile which is substantially flat; wherefor its object to' provide a dovetailed tile by by when (meme is laid uponthe other the angle which a waterproof and light-tight roof: may be turned through when passing from the curved constructed. An interlocking roofing tile accordportion of the upper tile on to the main surface 5 ing to the invention comprises one or more head of the lower tile is also obtuse. The extremity i ribs, an underneath bottom closing rib set back of the lower end may-be constituted by a rib n from the bottom edge of the tile and adapted substantially normal to the plane ,of the plate to engage with a head rib of the next lower tile, This form of construction not only gives the 7 an upwardly directed rib running along or adwhole roof a pleasing and quiet appearance, but 10 'jacent to one side edge of the tile and forming has the further advantage ofgiving the water the boundary wall of ,a main water trough, said a rapid flow off, because the curved surface of the boundary wall having a longitudinal groove in'lower end will quickly drain the water off the its upper surface constituting an auxiliary water surface 1' softhat any. penetration of water below trough, and a pair of underneath side closing the end of the tile is not possible, as-in the case ribs one running along or adjacent to'the side ,of ordinary straight edged tiles.

On the under surface ofthe about its right hand longitudinal edge and shows tile at the lower end is a closing rib g which is set the underneath of the tile. back from the rib n and rests against the rib f The tile according to the invention consists of an adjacent tile when laid, the rib g having of a flat or almost flat plate i, having a bottom notches h in which projections hi and IL2 of the 50 portion and a side portion, (right hand of Fig. 1) adjacent tile engage. Thus when four tiles are both of which portions overlap the tile underlaid together, they will be given the usual stagger neath to a considerable extent. The lower end as is shown in Fig. 3. There are two oblique or bottom portion of the plate i is bent downopenings ii in the closing rib 1 through which wards, as shown in Fig. 4, preferably so that its openings ii the water accumulating at the head surface forms an obtuse angle to the main surof the tile is led on to the flat surface thereof.

UNITED STATE.

In addition to the rib 71.2 there is provided a further rib -'h3, both ribs hi and n3 preventing the water from coming out where adjacent tiles abut.

On the unders de of thetile there is provided a longitudinal waveshaped rib k having a hole 0| for tying purposes, a similar hole 02 being provided in a cross rib 2 at the lower end of the tile. By providing the rib is, warping of the ti1e durmight occur while laying the tiles.

The lateral edges of the lower extremity n of the tile are provided with notches m on the undercan drip off more easily, the extremity n being somewhat thicker at the lateral edges to accommodate the notches. At the top end of the tile on the underside thereof is provided a rib p by which the tiles may be hung from the laths.

As shown in Fig. 5, the bottorn of the-main trough b To this end the upper head-rib e is madsorn what thinnerat el and the closing rib f is simito a greater extent than in the case of the tile trernity or rib n and the rib 9 above it, are carried from the trough.

As a result of the curving of the ribs g and n on the underside of the tile, it is possible to carry correspondingly, the lower e X-g the rib c to the end of the rib 11. In thisway the watertrough is shut off completely to the edge of What I claim is:

1. An interlocking roofing tile having an upwardly directed rib running along or adjacent 'ndent outlet passage for water, and a pair of underneath side closing ribs, one
