page_text: I, LEOPOLD STÖGER, of N 6, Hausmening, Lower Austria, in the Empire of
Austria, Tile Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This improved roofing tile, which is formed of sand and cement, is characterised
essentially by a bar ridge or flange being formed on the upper face of the tile
to engage in a counter groove formed in the under face of the adjacent tile. By
this means, on the one hand, there is afforded an excellent protection against
the penetration of water or snow and, on the other hand, the fall of pieces of
broken tile from the roof is prevented, as each broken piece is wedged firmly to
the corresponding counter piece. As further, as already stated, this tile is formed
of cement and sand without burning, the cost of producing same is very moderate.
In the accompanying drawings,
Figure 1 is an elevation of the upper face of the tile;
Figure 2, a view of the under face of the tile;
Figure 3, a longitudinal section on the line -x of Figure 1; and
Figure 4, a view of a roof covering formed of these tiles.
A is the tile which has its upper face provided with edge bars, ridges or
flanges a, and its under face with a counter groove b. These roofing tiles are as
usual attached to the laths or rafters by means of hooks or projections
c so that
two side hooks e of a row of tiles I always engage with one another. When the
upper row of tiles II is laid on the roof, the ridges a engage in the counter
grooves of the under face of the tile, so that the objects mentioned at the
commencement of the present specification are attained.
I, LEOPOLD STÖGER, of N 6, Hausmening, Lower Austria, in the Empire of
Austria, Tile Manufacturer, 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:--

....
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. A counter grooved roofing tile, the upper face of which has bars or ridges (a)
adapted when used on a roof to engage in counter grooves (b) in the under side
of the adjacent tiles, substantially as herein before described.
'
2. The manufacture of the roofing tiles herein before described, from sand and
cement,
