Improvements in Roofing Tiles.
I, FRANZ MAURITZ DALHOFF, of 354 Bahnhofstrasse Borghorst, i/ W. Germany,
Master Bricklayer, 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 :-
My invention relates to a lipped roofing tile in which the lips are arranged in a
manner which enables the roofing to be done in a perfectly air-tight manner and
renders special fastening devices unnecessary.
My improved roofing tile is constructed in the manner shown by the accom-
panying drawing in which
:-
Figure 1 is a view showing a roof partly tiled.
Figures 2 and 3 are views in plan and side elevation respectively of a
whole tile.
Figures 4 and 5 are views in plan and side elevation respectively of a half tilo
divided vertically.
Figures 6 and 7 are views in plan and side elevation respectively of the lower
half of a tile divided horizontally.
Figures 8 and 9 are views in plan and side elevation respectively of the upper
half of a tile divided horizontally.
Figures 10 and 11 are views in plan and side elevation respectively of a quarter
tile the half of the upper half of a tile as shown by Figures 8 and 9.
Figure 12 is a view in plan of a modification in the shape of the tile, and
Figure 13 is a view in side elevation showing a tile with an undercut lip at its
tail end.
Throughout the views similar parts are marked with like letters of reference.
The body or pan a of the tile may be of any desired shape. On the top half of
the tile is a lip which extends along its edge on the upper face thereof, and on
the lower half of the tile is a similar lip on the underside, or face thereof as
indicated by dotted lines in Figures 1. 2. 4. 6 and 12 of the accompanying
drawing.
For the purpose of fastening the tile to the lathing or woodwork c, each tile is
provided on its underside-at the top or tail end-with a lip or projection which
is preferably undercut as shown by Figure 13.
In order to increase the firmness of the bond or connection of the tiles with one
another they are each provided with a lateral projection e on one side and with a
lateral recess on the other side as shown by Figures 1. 2. 4. 6 and 12 of the
accompanying drawing.
When the lip or projection d is undercut it is advisable to also bevel off the
laths or woodwork c to properly engage with the said lip or projection.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvements in roofing tiles, substantially as hereinbefore described and
illustrated by the accompanying drawing.
2. A roofing tile having a projecting lip such as running round its upper half
on the face thereof, a similar projection running round its lower half on the
underside thereof and a lip or projection such as d at its top or tail end on the
underside thereof, as and for the purpose set forth.

forth.
