Improvements in Roofing Tiles or Plates.
I THEODOR HILDEBRAND of Spring Strasse, 84, Gartow, Germany, Tin Smith,
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 roofing tiles or plates of simple construction which can
be easily and quickly fitted together so as to interlock with one another in a firm
and tenacious manner.
The accompanying drawings shew the construction of these tiles or plates and
the manner in which they interlock with one another.
Figures 1 and 2 shew parts of a parallel roof and an ogive roof respectively with
these tiles or plates fitted thereon;
Figures 3 and 4 are respectively front and side elevations of a single tile
or plate.
The tiles or plates are by preference made of sheet zinc and are of quadrangular
shape. As shewn in Figures 3 and 4, the tile or plate a is formed with a groove
or channel b¹ along each of its edges, two of said grooves or channels, which are
adjacent to each other, being turned towards the front surface of the tile or plate
as shewn at b, and the other two grooves or channels 6 being turned towards the
rear surface of the tile or plate a.
When roofing in a house or covering any kind of surface with tiles or plates
made in accordance with this invention, the method to be observed is as follows:-
The two upper grooves of the one tile are joined to or connected with the grooves
of the second tile lying below-an operation which can be quickly and easily
effected.
As shewn in Figure 1 the tiles are affixed to the purlins c by means of nails or
pins d. The best kind of nails for this purpose are those with flat sunk heads, as
these do not project above the tile. Still even without these nails a thoroughly
safe and reliable hold is obtained by the special disposition of the grooves or
channels b and b¹ in the tiles or plates, hence they are especially and highly suitable
for very steep or sharply sloped roofs.
Figure 2 shews an ogive or cross roofing of these new tiles. As may be seen
from this figure the tiles or plates a are cut away on one side whereby triangular
shape is imparted to them. The cutting away of the tiles or plates is determined
by the side on which a commencement of the roofing work is made. For instance
when the work is commenced below at the right side the cut tiles or plates would
then be used. Although the drawing represents merely a lath-work frame, it will
of course, be clearly understood that the tiles or plates can be used on scale work
with equal advantage.
These tiles or plates, which may be made of any desired material, have a further
great advantage, namely that on account of their lightness, they may also be used
for sheds, and exhibition buildings.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A tile or plate for roofing of all kinds, made of a quadrangular shape and formed
with grooves or channels along each of its sides, the grooves or channels along two

page_text: turned to the rear of the tile or plate so that two or more tiles or plates can be
joined together in a firm and tenacious manner by simply interlocking their
oppositely disposed grooves or channels-substantially as described and illustrated.
