An Improved Roofing Tile.
I, LEOPOLD NÖTH, of Friesenhofen, Allgän, in the Empire of Germany,
Engineer, and LUDWIG HELD, of Waldsee, Württemberg, in the Empire of
Germany, Banker, 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 subject of the present invention, is an overlapping tile with double lap,
which admits of forming a perfectly close roof, smooth on the outside; and at
the same time admits of changes in the position, in consequence of slight changes
in the supports, differences in the bedding, and unequal contractions, without
interfering with the closeness of the joint. Also, the entrance of water or snow,
by its being blown in by the wind, is prevented; and the carrying off of any water
that may have formed by sweating, is provided for.
The annexed drawings illustrate the invention,
Figure 1 shews a view of a tile, seen from above.
Figure 2 is a view of the tile inverted.
Figure 3 is a longitudinal section; and Figure 4 is a cross section taken through
two tiles lying side by side.
The form of the plan of the tile is that of the common "Beaver-tail" tile.
The outer surface possesses no protuberances at all, and may be provided with
channels f for guiding the water, between which there are smooth surfaces e;
or be without them, as desired.
At both sides there are longitudinal ledges g, one of which has a double lap
joint on the lower surface, and the other a similar joint on the upper surface.
These joints consist of or are made up of the groove k in the upper surface of
the lower ledge, closed at the top end, tongue, and the outside groove h; while
the surface of the tile ledge which engages with it is constructed correspondingly
to make the jointing, as shewn.
The under side of the tile is provided with a fastening or holder at the top end,
which sits behind the roof batten; and below, it has one or two ledges i, one of
which is formed by a thickened edge of the tile, and forms a weir. These ledges
prevent water or snow from being driven in.
In the centre, an angular ledge provided, which carries off at both sides any
water formed by sweating. Owing to this construction, it is not necessary.
to make the tile hollow, for the purpose of obtaining the thickness necessary for
the jointing.

Without endangering the closeness of the joint, these double beaded joints may
have so much play that the tile may shift slightly in any direction. The tile
illustrated is such that it may easily be manufactured in a rotary drum press,"
or any other press for making tiles with overlapping edges, in plaster or iron
moulds.

The tile may be made of cement, clay, or similar material.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is:-
-
1. A roofing tile having joints, substantially as and for the purposes set forth.
2. A roofing tile having side lapped, or groove and ridge joints, and a ledge, or
ledges, as ; substantially as and for the purposes set forth.
3. The roofing tile particularly as shewn in and set forth with reference to the
drawings.
