"IMPROVEMENTS IN TILES OR PLATES FOR ROOFING." A communication from
abroad by Wilhelm Conraetz, August Carl Rieder, and August Schuchart, all
of Vienna, Austria.

PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 8th October 1877.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN TILES OR PLATES FOR
ROOFING." [A communication from abroad by Wilhelm Conraetz, August Carl
Rieder, and August Schuchart, all of Vienna, Austria.].
This Invention relates to improvements in tiles or plates for roofing, and consists
in constructing the said tiles or plates in such a manner that they may be fitted
together tightly without overlapping too far. For this purpose each tile is provided
along its four edges with projections or flanges, of which two enclosing. one angle
are turned up, while the other two enclosing another angle are turned down.
Each right up-turned flange on one tile fits on a left down-turned flange on
another tile, and vice versa.
When the tiles are put together to form a roofing, each of the up-turned flanges of
the two edges forming the upper corner of one tile will therefore be overlapped by
one of the lower down-turned flanges of two other tiles, while each of the two down-
turned flanges of the two edges forming the lower corner of the first-mentioned tile
will overlap one of the upper up-turned flanges of two other tiles.
The tiles may be of any convenient size and of any suitable material, such as

page_text: metal, clay, porcelain, wood, fibrous substances or the like, and are formed or
stamped in suitable moulds or dies.
When the tiles are formed of thin sheet metal, they may be corrugated in order to
stiffen and strengthen them.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Robert Lake in the Great Seal Patent Office on the 6th April
1878.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN TILES OR PLATES FOR
ROOFING." A communication from abroad by Wilhelm Conractz, August Carl
Rieder, and August Schuchart, all of Vienna, Austria.
This Invention relates to improvements in tiles or plates for roofing, and consists
in constructing the said tiles or plates in such a manner that they may be fitted
together tightly without overlapping too far. For this purpose each tile is
provided along its four edges with projections or flanges, of which two, enclosing
one angle, are turned up, while the other two, enclosing another angle, are turned
down.
Each up-turned flange on one tile fits under a down-turned flange on another
tile. Therefore when the tiles are put together to form a roof, each of the up-
turned flanges of the two edges forming the upper corner of one tile will be over-
lapped by one of the lower down-turned flanges of two other tiles, while each of
the two down-turned flanges of the two edges forming the lower corner of the first-
named tile will overlap one of the upper up-turned flanges of two other tiles.
The said tiles may be made of any convenient size and of any suitable material,
such as metal, clay, porcelain, wood, fibrous substances, or the like. They are formed
or stamped in suitable moulds or dies.
When the said tiles are formed of thin sheet metal, they may be corrugated to
stiffen and strengthen them.
In the accompanying Drawing,―
Figure 1 is a plan partly in section of a number of tiles arranged and fitted
together in accordance with this Invention; Figures 2, 3, and 4 are sections of
Figure 1 through the lines x, x, y, y, and z, z.
Figure 5 is a view of a single tile stamped out of sheet metal.
Each tile is provided with two down-turned flanges a, a', and two up-turned
flanges b, b'.
As shown in Figures 1, 2, 3, and 4, each up-turned flange 6 or 6¹ on one tile
fits under a down-turned flange a or a' on another tile.
When the tiles are put together to form a roof, each of the up-turned flanges b, b¹,
forming the upper corner of one tile, will therefore be overlapped by one of the
lower down-turned flanges a, a¹, of two other tiles, while each of the two down-
turned flanges a, a¹, of the two edges forming the lower corner of the first-mentioned
tile will overlap one of the upper up-turned flanges b, b, of two other tiles.
The tile shown in Figure 5 is stamped out of sheet metal, and provided with

page_text: corrugations serving to stiffen the same, and to give it an ornamental appearance.
It may be fastened to the lath of the roof by a single nail driven through the hole c
in its upper corner. Such a tile of sheet metal may be advantageously made about
Bix or seven inches square, and about a quarter of a pound in weight.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,
First. The construction and arrangement of tiles, as above described, and as
shown in Figures 1, 2, 3, and 4 of the Drawing.
Second. The construction of tiles, as above described, and as shown in Figure 5
of the Drawing.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Sixth day of April, in the year of our Lord One
thousand eight hundred and seventy-eight.
W. ROBT. LAKE (L.S.)
