Improvements in Roofing Tiles.
I, ABRAHAM WEIL, of Steinheim, Westphalia, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention, and in which 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 of which various examples are illustrated
in the accompanying two sheets of drawings, in which
Figure 1 is an underside view of a roofing tile constructed in accordance with
my invention, Figure 2 a view of the upper side of same, and Figure 3 a section on
line x-x of Figure 1.
Figure 4 is an underside view of a similar tile slightly modified, Figure 5 a view
of the upper side of same, and Figure 6 a section on line y-y of Figure 4.
Figure 7 is an underside view of a similar tile still further modified, Figure 8 a
view of the upper-side of same, and Figure 9 a section on line 2-2 of Figure 8.
Figures 10 to 12 show to a larger scale three forms of jointing for two adjacent
roofing tiles of the kind herein described.
In the example shown in Figures 1 to 3 both the upper overlapping fillets a of
the roofing tile are provided at their inner edges with a notched groove b, whilst
each of the lower overlapping fillets c is provided with a projecting tongue d,
which is cut away at intervals as shown so as to produce projections e which take
into the notches in the groove of the upper fillet a.
The upper fillets a of the example shown in Figures 4 to 6 are also each
provided with a notched groove f. The projecting tongues 7 of the lower fillets c
have diamond-shaped projections g formed in them which take into the notches in
the grooves of the upper fillets a.
The corners m of these roofing tiles may be of zigzag shape as shown in
Figure 10 for example; but they may also be shaped as shown in Figures 11
and 12, in which the angular part m' is formed of curved and straight surfaces.
By the use of this angular jointing corner no intermediate material is necessary for
making a tight joint.
In consequence of the serrated form of the grooves and tongues of the over-
lapping fillets, as shown in Figures 1 to 6, the serrated part of the tongue of one
roofing tile takes, teeth-like, into the notches of the grooves of the next roofing
tile. By these means a storm-proof roof covering is formed, all the parts of which
are connected with each other in every direction, and in which the joints of the
overlapping fillets are so arranged that drifting snow, water and dust cannot
penetrate into the inside of the roof through the numerous grooves and tongues
and other connecting parts.
In the roofing tile shown in Figures 7 to 9 the upper overlapping fillets a are
provided with grooves h, and the lower overlapping fillets, at the points where they
come together, have short projecting tongues i which take into the grooves of the
upper overlapping fillets.
In this arrangement the notched groove prevents the entrance of driving snow,
water and dust because by its means the only passage by which such can enter is
so broken up and interrupted that it is practically closed; the form of the roofing
tile, and the upward inclination of the groove and of the joint tend towards the
same result. The underside of the roofing tile is preferably furnished with parallel

page_text: Tos & whereby the thickness of the tile may be reduced without
prejudice to its strength.
These roofing tiles may be made of any suitable material.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
First. A roofing tile having angular corner joints and two connected over-
lapping fillets on the upper and under sides thereof, the lower overlapping fillets
being provided with serrated tongues, and the upper overlapping fillets with
notched grooves adapted to receive the said serrated tongues, substantially as
.described.
Second. In a roofing tile of the kind forming the subject of the first claiming
clause hereof, the use of a projecting tongue at the corner where the two lower
overlapping fillets are connected together, substantially as described.
Dated this 31st day of March 1896.
