Improvements in and relating to Roofing Tiles.
I, CARL WILHELM VOIGT, Manufacturer, of Görlizz, 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:-
This invention relates to an improved roofing tile. The tile is simple in
construction and can be manufactured very cheaply.
And in order that my said invention may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon:―
Fig. 1 is a plan view of the tile.
Fig. 2 is a longitudinal section of the same.
Fig. 3 is a cross section.
Fig. 4 shows a portion of roof covered with the tiles.
The new tile, as shown clearly on the drawings, is provided at one side with a
longitudinal rib a and at the other side with a longitudinal moulding or catch b.
Both the rib and the moulding extend the full length of the tile and the moulding
is so shaped, as shown at Fig. 3, that when the tile is inserted in place, as shown
at Fig. 4, it catches on or grips the rib a of the next adjoining tile. At or about
the centre of the tile there is made an arch d which extends, as shown, from the
lower edge of the tile to about one-third its entire length. When the tiles are
fitted in place the arch d of one tile is, as shown clearly at Fig. 4, capable of fitting
over the upper part of the moulding b of the tile immediately below it in the next
row of tiles.
Two projections f are made at the underside of the tile for the purpose of
securing it to the roofing boards or purlins.
When fitting the tiles in place on a roof it is necessary to proceed from right
to left the moulding b of dne tile being fitted over the rib a of the previously fixed
tile so as to render the tiles water-tight at their butt joints. As the arch d of
each tile in one row covers over the upper end of the moulding 6 of each tile in
the row below it follows that not only is water prevented from entering at the
upper ends of the mouldings 6 but that the tiles can be arranged in rows at
distances nearer to or farther away from each other, so as to suit the distances
apart of the purlins to which they may be secured, without danger of water gaining
access to the joints.
The tiles are of a uniform thickness throughout which is a great advantage as
tiles of a uniform thickness are much more durable than tiles of a variable
thickness.
The tiles are made in presses which first produce a flattened strip of clay and
then stamp the strip into the shape of the tile.
The tiles are strong and have a clean and smooth appearance.
As these tiles can be easily and cheaply manufactured it is expected that they
will soon come into general use.

page_text: 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 consider novel and desire to claim is:-
1. A roofing tile made of a uniform thickness throughout and having an arched
part for covering over the upper part of the overlapping joint of the next lower
tile, substantially as herein before set forth.
>
2. A roofing tile made of a uniform thickness throughout and provided with an
arched part (d), a rib (a) and a moulding (b), substantially as hereinbefore
described with reference to the drawings annexed.
3. The manufacture of a roofing tile as claimed above in a press which first
produces a flattened strip of clay and then presses it into the desired shape,
substantially as hereinbefore set forth.
