I, JULIUS THEodor Köhler, of 12 Bahnhofstrasse Limbach in Sachsen in '
the Empire of Germany. Manufacturer do hereby declare the nature of this invention
to be as follows:-
This invention relates to tiles made in the, form of.a rhombus or rhomboid and
said.
intended to overlap each other at the edges for roofing or other purposes,
tiles being usually formed to have one of their four corners uppermost so that the
longer diagonal is in a vertical plane and the shorter diagonal in a horizontal. plane,
and the improvements are applicable to these and similar.tiles and more particularly
consist in providing the tile on the upper side along two of its edges and on the
lower side along the remaining two of its edges with two parallel ridges or beads.
at each said edge, whereof the face of the inner ridge or bead is inclined from the
outer ridge or bead to form an angular recess. In the fitting of the. tiles together
this construction of duplicate ridging having an. inclined face permits.of.the
expansion and contraction of the tiles without loss of weather-proof joint.
The invention further consists in placing at that corner of the tile which is to
be regarded as its apex, on the upper face of the tile an angular projection
extending inward. between the ridges aforesaid for a longer or shorter distance,
upper face &
bisecting the angle between the ridges. This projection has in its
tapered recess broader at its lower end and tapering. to nothing at the apex of the
tile. This projection is intended to form a weather proof joint to prevent access
of water between the meeting ridges of the tiles. …….

Improvements in Tiles.
I JULIUS. THEODOR KÖHLER of 12 Balinhofstrasse, Limbabh in Sachsen; in
the Empire of Germany, Manufacturer, do hereby declare the nature of this
invention and..in..what manner the. same is to be performed to be particulacly
described and ascertained in and by the following statement:
This invention relates to tiles made in the form of a rhombus or.rhombold and
intended to overlap each other at the edges for roofing or other purposes, said' tiles
being usually formed to have one of their four corners uppermost, so that the
longer diagonal is in a vertical plane and the shotter diagonal. in a horizontal
plane, and the improvements are applicable to these and similar tiles. and, more
particularly consist in providing the tile on the upper side or surface along two of
its edges and on the under side or surface along the' remaining two of its edges
with two.,parallel„ridges, or beñds at each, said edge, whereof the face of the inner

page_text: Tinging Having an
inclined face permits of the expansion and contraction of the tiles without loss of
weatherproof joint.
The invention further consists in placing at that corner of the tile which is to be
regarded as its apex, on the upper face of the tile an angular projection extending
down between the ridges aforesaid for a longer or shorter distance, bisecting the
angle between the ridges.
This projection has in its upper face a tapered recess broader at its lower end
and tapering to nothing at the apex of the tile. This projection is intended to
form a weatherproof joint to prevent access of water between the meeting ridges
of the tiles.
In the annexed drawings
Fig. 1 shows a plan view of a number of tiles fitted into each other in their
intended position.
Figs.
2 and 3 are longitudinal sections on lines R, R and S, S, respectively
of Fig. 1.
Figs. 4 and 5 represent a horizontal section on line T, T, and plan of three tiles
adjoining each other, with short grooved tongue.
Figs. 6 and 7 are similar views of tiles with longer grooved tongue.
Figs. 8 to 11 are representations of a single tile having a short grooved tongue
respectively.
Figs. 12 to 14 are similar views with longer grooved tongue.
The plate proper of the tile which may have a smooth surface or be corrugated,
is at its upper ends or edges provided on its upper face with the parallel
ridges A and B whereas its lower edges are fitted with similar ridges A¹ and B',
the latter however projecting inwardly from the under face of the tile. The inner
of said ridges A and A' are so shaped that they slope or incline towards the
adjoining outer ridges, thus forming an angular recess. The said plate is besides,
at the uppermost corner provided with a projection or nose N.
The upper strips A, B, and the lower strips A', B', of each two adjoining tiles
engage with each other.
Of essential importance as regards the joining or connecting together of the
tiles is the way in which the three upper tiles are united to the lowermost (see
Fige. 5 and 7). Provision is here made for forming close joints and diverting the
water that would concentrate at the point where the ridges A, B of the covering
tile meet with the upper surface of the lower tile. For this purpose the angular
projection H provided with the groove his constructed, above which projection
the joint of the two other tiles is formed. The object therefore of the grooved.
projection H is to prevent any water that runs through said joint f, from passing
into the groove b between the ridges A and B, it being diverted by said groove h
and led to the upper surface of the lower tile.
The tongue H may project downwards for a shorter or longer distance, as shown
in Figs. 1 and 5, 8 to 11 and Figs. 1 and 7, 12 to 14 respectively the latter form
however being the preferable one as it is a surer means for leading off the
water.
Said projection H lying as shown in Fig. 7, between the inner ridges A, A of
the lower tile prevents in a reliable manner the entering of water that may run
through the joint f.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
An improved tile in the shape of a rhombus or rhomboid, provided with
ridges B B and A, A' respectively, the latter being inclined towards the outer
ridges so as to form an angular recess, to permit of retaining a waterproof joint
with expansion or contraction of said tile, the said tile being also provided with

page_text: the grooved projection H for the purpose of leading off any water that may run
through the joint ƒ of adjacent tiles substantially as described and illustrated.
