Improvements in or relating to Roofing Tiles, Slabs, or the like.
I, CARL WICKE, Builder, of l'arallelstrasse 28, Lehe, Hanover, Empire of
Germany, 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:
-
The present invention relates to roofing tiles or the like which when properly
arranged offer an absolute protection against water passing through without
it being necessary to cement the joints or edges.
The special quality of the tiles is due partly to their rhomboidal shape and
partly to the fact that each tile is provided along the two upper edges of the
upper surface with ledges or ribs, and corresponding grooves on the underside
into which the ribs of the tiles fit, Besides these there are on the upper
surface, and at certain distances from the said ribs grooves parallel to them,
which become gradually shallower and flush with the surface of the tile at their
lower ends, at say a few centimetres distance from the edges. On the under-
side of the tile there are corresponding ribs arranged to fit tightly into the
grooves, thus forming, together with the edge ribs fitted into corresponding
recesses a kind of hook for securing the tiles, a dove-tail or other shaped
recess being provided at the side edges to fit a corresponding projection on a
neighbouring tile, thereby forming not only a very superior connection of the
tiles but also an arrangement which will well stand against storms. The various
directions of the surface where the tiles are arranged to overlap has the effect
that the wind cannot drive the water through between the contact surfaces, whilst
the gradual decrease of depth in the upper grooves facilitates the running off
of the water collecting in them.
The invention is represented in the accompanying drawing in which
Figure 1 is a plan view of a tile and a corresponding section.
Figure 2 an underside view also with a corresponding section and
Figures 3 and 4 are views showing the arrangement of the tiles as arranged
on a roof.
The tiles A made of clay, cement, or other suitable material, are of a rhom
boidal or diamond shape. At one of the obtuse corners of the tile is arranged
a recess while at the other obtuse corner a corresponding projection is formed.
The two upper edges of the upper surface, Figure 1, are formed with ledges
or ribs a adapted to fit into corresponding grooves d. Figure 2, formed on the
under side of each tile. At a short distance from the ribs a grooves bare
formed parallel to a, which however do not extend quite to the edge and become
gradually shallower towards the lower end. Into these grooves fit ribs c
correspondingly formed on the under face of the tiles. The projections and
grooves are so fitted to one another that the surfaces or edges h (Figures 3 and 4)
lie flush with and in close contact with the surface of the under tile. By means
of the hooks e the tiles are hung on the laths of the roofs as shown in Figure 4.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
1. Roofing tiles or the like provided with ribs, such as a on the upper edges
of their upper surface, and corresponding grooves on their under surface and
grooves such as 6 arranged parallel to the ribs, and corresponding to ribs on
their under face, said grooves not extending to the edges of the tile and becoming
shallower towards their lower ends, substantially as described.
2. The complete roofing tile or the like substantially as described and illus-
trated in the accompanying drawings.
