page_text: I KARL WEISE of Dermbach, Germany, Builder do hereby declare the nature of
my 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 refers to improvements in roofing with flat pantiles. This newly
designed pantile has a perfectly flat outer surface and only has a little ridge on the
upper end over which the pantile above it laps, so that the roof when finished
presents in each row a perfectly flat surface.
In the accompanying drawings
Figure 1 shows a piece of the roof in plan.
Figure 2 a section of figure 1 on line a b.
Figure 3 a side view of the flat pantile.
Figure 3 the same in plan view.
Figure 3 longitudinal section of the tile.
Figure 3 a plan of the under side.
Figure 3d a vertical section of the tile.
Figure 4 the ridge tile for this roofing.
Figure 5 lining strips for the edges of the tiles.
The tile A has on its under side a light projecting rim a a Figure 3° so that only
a very small surface rests on the purlin thus preventing a rotting of the purlin as
much as possible, which is often the case when the tile rests with its entire surface
on the purlin. In the lower end of the rim a is a projection b across the whole
width of the tile which laps over the projection c on the upper end of the top of
the tile put down in the lower row Figures 3, 3b, 3c. The under side of the tile
has on its upper end two lugs or projections e e which are placed behind the purlin
in roofing. Between the purlin and the lugs ee which are furnished with conical
grooves a long cork is pressed so that the tile is properly fixed Figures 2, 3º, 3ª
The edges of the length sides are plowed with grooves f f Figures 3 and 3d and
between each two tiles the tongues g of asphalt felting are placed; these tongues
may also be made of cork strips soaked in chloride of calcium or in a silicious
solution. Between the upper and under projecting ridges b and c may also be
placed similar tongues h h Figures 1 and 2.

page_text: The roofing is done on purlins of the usual size in the usual manner, but great
care must be taken in fixing the purlins exactly and in the manufacture of the
tiles.
If the roof is finished in this manner and the ridge tiles (Figure 5) fixed a
penetration of rain or snow is impossible, and the roofing can also stand a slight
rocking or shifting of the structure of the roof.
Repairs are also easily executed as it only needs removing the corks k k and the
tongues g g to enable the defective tile to be taken out and replaced by a new one.
The ridge tiles can be placed without mortar or nails.
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
1. In roofing with flat pantiles the use of tiles which are flat on the outside and
only furnished with a projecting rim such as c on the upper end over which laps
the nether projecting rim 6 of the following tile substantially as specified.
2. A roofing tile having on the under side a light projecting rim such as a ɑ ɑ ɑ
on whose upper end are the lugs e e which serve to hold the tile on the purlin these
lugs e e having conical grooves for corks to be placed between the lugs e e and the
purlin to properly fix the tile substantially as and for the purpose specified.
3. The combination with a roofing tile having its larger edges grooved of tongues
such as g g of asphalt felting employed substantially as specified and for the purpose
of making the roof watertight without the use of mortar.
