Improvements in and relating to Roofing Tiles.

all of Christiania in the Kingdom of Norway, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to a method of covering house roofs with flat tiles especially
formed to suit the said roofs, by means of which the inconveniences attending the
use of the usual bowed tiles and the older construction of flat tiles, are sought to be
removed, and by which the advantages of slate roofs are attained.
The improved tiles are made square or rectangular, and are laid on the roof in
such a manner that the sides of the said tiles form an angle of 45° with the edge of
the roof, the laths being also laid at the same angle with the said edge of the roof,
against which with slate and the usual covering of tiles they lie parallel with the
same.
This method of covering roofs gives a solid, tight and safe covering, which
combine the cheapness of the tiles with the advantages of a slate covering.
It also has the advantage, that it may be laid down in cement or similar material
at a small cost and forms thereby a completely tight roof.
The invention is represented in the accompanying drawing in which,
Figure 1 is a plan of the improved tile.
Figure 2 is a plan of the underside.
Figures 3 and 4 show edge views of Figures 1 and 2 respectively.
Figure 5 is a plan of part of a roof covered with the improved tiles, and
Figure 6 is a section on the line y y of Figure 5.
The tile, which may be of burnt clay, glass or other suitable material, is flat and
of square or rectangular form with a projection a in a line. with one side and of
about the same height as the thickness of the tile, and of a length somewhat less
than the side of the tile so that at each end there is a small cut away portion b, the
size of which depends on the extent to which the tiles are to cover each other.
Figure 6 shows how the projection a rests against the lathe of the roof and holds
the tile in place.
The corners d of the tile are cut off parallel and rest against each other under
the covering and are entirely covered by the sharp corner of the tile above as shown
in Figure 5.
All the tiles in the same horizontal line lie in the same plane.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. For the covering of roofs the arrangement of sloping laths and the use of
square, flat tiles, one edge of which is furnished with a rib and two corners of
which are cut off.
2. The flat tile mentioned in Claim 1 characterized by having two of its opposite

2. The flat tile mentioned in Claim 1 characterized by having two of its opposite
corners cut on and one of its sides furnished with a rib, which is cut away at
both ends.
