I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for "IMPROVEMENTS IN ROOFING TILES
a communication to me from abroad by François Louis Perrière, Gentleman of
Paris, in the French Republic, and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
It is well known that the ordinary tiles are far from satisfactory as a roof
especially as they allow the air in the house to be effected by the outside
temperature, thus in suminer when the tiles are hot the intense heat is transmitted
to the upper rooms making them unbearable while in winter when covered with
snow the reverse occurs.
The object of this invention is to construct tiles so that the air in the house
is unaffected by the outside temperature at the same time being easier and more
cheaply laid.
In the drawings Fig. 1 shows a tile A provided with hollow spaces C one of the
sides being provided with a projecting lip E, the other having a vertical c rre-
sponding recess or depression F so that each tile can be placed with the part E over
the part F on the next and so on.
In order to clear the tiles of the water from rain and snow they have longitudinal
channels M cut in different directions as required, they are also provided with
cuttings or projections N at suitable places to facilate repairs by affording a
foothold for the labourer.
Figs. 2 and 3 show tiles B. D with modifications of the lip and recess at the sides
for instance in Fig. 2. the under part H is cut away; in Fig. 3 there is another
angle, thus the shape can be convex as in Fig. 1. vertical as in Fig. 2 or irregular as
in Fig. 3.
Figs. 25 and 26 show a vertical of a roof a, b, and a¹ and b¹ in their natural
inclination covered with these tiles.
Fig. 4 shows a modified tile p the under side of which is corrugated the sides I
and having suitable corresponding sections O.

page_text: Fig. 5 shows a peculiar form of tile one side being raised, to be laid on the
roof all band covered with another tile d as shown in Fig. 27.
In Fig. 6 the tile S has all its hollow spaces c the same size the lip T going over
the ridge U.
Fig. 7 shows one or more layers of tiles with water stoppers Z placed one above
the other N° 1 and 2. resting on the beams V V' and V₁ and Nos 3 and 4 under 1
and 2 resting on suitable iron carriers x and y attached to the wooden beams.
Figs. 8 to 12 show different joinings of the ends p and q of tiles intended for use
vertically as wall tiles.
The joining of the tiles shown in Figs. 25 and 26 can have many different shapes
some of which are shown in Figs. 13 to 24 their construction being so simple that
no further description is needed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is =
The construction of roofing tiles with internal hollow spaces, or corrugated,
substantially as herein before described, and illustrated in the drawings.
