A New or Improved Roofing Tile.
I, KURT SCHELZEL, of 4 Lindenauplatz, Dresden, in the Empire of 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 roofing tiles so constructed that, the rain water is
conducted away from them, without washing, over their joints,, and that by means
of grooves and fillets on the edges of the tiles, they can be connected together by
cement or other suitable material so as to offer effective resistance to the action of
storms.
In the accompanying drawings
:-
Figure 1 is a top view of a tile made in accordance with my invention with one
groove and one fillet formed in or on the side edges thereof.
Figure 2 is a section taken on the line w w of Figure 1.
Figure 3 is a top view of a tile with two grooves formed in its side edges.
Figure 4 is a section taken on line a x of Figure 3.
Figure 5 is a section similar to that shown in Figure 4 but with the grooves of a
different shape.
Figure 6 is a back or underside view of the tile.
In Figures 1 and 3 it will be seen that the tile is formed into a kind of double
gutter by the two longitudinal brims or flanges & and a central longitudinal rib c.
The object of the central rib c and the two brims or flanges d is not only to divide
the surface but to afford protection to the joints, which come in line with the
middle ribs e of the tiles next below them, and this protection is chiefly brought
about by the central rib c deflecting the rainwater towards the centre of each half
of the surface of the tile a and therefore sidewise from the joint. In order to
effect this removal more perfectly the lower part of the tile is so made that each of
the two gutter surfaces runs out into a kind of tongue, for the reason, more especially,
that when there is not too large a quantity of rain the water is inclined, on account of its
adhesion to the tile, not to fall direct on to the tile next below but to run along the
lower front side or edge to the lowest point of this edge, and then to run over on
to the next tile.
In the tiles shown in Figures 1, 3 and 6 this deepest point occurs at the lower
ends of the two tongues and these ends are considerably further away from the
joint than the sides of the central rib at the point where the water would naturally
fall from it, and they conduct the water to a greater distance from the joint than if
these tongues were not present, and the tile had a straight or half moon shaped
end. As in this arrangement water cannot wash over the joint it cannot get through
the same into the space below. On the underside of the tile and at the upper end
thereof is formed a peg or projection b for hanging the tile in the usual way. From
this peg or projection there extends downwardly in a straight direction a groove g
the back of which forms the central rib c of the upper side of the tile. For the
purpose of connecting the tiles sidewise to one another they are either made with a
fillet along one edge and a groove e along the other, the fillet being adapted to
enter the groove e of the adjacent tile as shown in Figure 2; or the tiles are made
with a groove e along both edges, the groove in one tile coming against the groove
of the next as shown in Figures 4 and 5, and the connection may be completed in
both cases by the insertion of suitable jointing material such as iron, cement, tubing,

page_text: felt, mortar and so forth.
The grooved adjacent edges of two tiles take into the
groove g in the underside of the tile lying over them, and it is through the protection
thus afforded to the joint and the connection of the tiles by means of the grooves
and fillets, or of the grooves alone with the aid of suitable jointing material, that
roof covering is produced.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The new or improved roofing tile having a brim or flange d at each side or edge,
one of the said sides or edges being furnished with a groove e and the other with a
fillet as in Figure 2; or both sides or edges with a groove e e as shown in
Figures 4 and 5, the upper side of the tile having also central rib c, and the under
side a groove g, the lower end of the tile terminating in two tongues, substantially
as described and for the purposes specified.
