PROVISIONAL SPECIFICATION left by the said George Anthony Marsden at
the Office of the Commissioners of Patents on the 4th October 1877.

"IM-
PROVEMENTS IN AND RELATING TO TILE COVERINGS FOR WALLS AND OTHER
STRUCTURES."
Tiles for ornamenting walls are very apt to get loose and fall off, and large
numbers of Patents have been taken out for modes of keying them into the walls,
none of which however appear effective.
Now my Invention consists in keying the tiles into each other instead of, or as
well as into the wall. There are several ways of doing this, such as tonguing and
grooving, but the plan I prefer most is to construct a projecting flange on the
back part of two edges of each tile to fit behind the one below (or above) and on
one side of it.
The tile can be thinner on the two opposite sides if desirable.
The backs of the tiles are roughened in any desirable manner, and are fastened
to the wall with cement or otherwise. Their faces are variegated in any desirable
manner, and their material any suitable stuff that slabs or tiles are made of.
These ornamented tiles can be used for the interiors of walls built in accordance
with the Invention of John Sidebotham, for which Letters Patent were granted,
bearing date the 2nd day of June 1876, and of which I am part proprietor.

IN AND RELATING TO TILE COVERINGS FOR WALLS AND OTHER
PROVEMENTS
STRUCTURES."
Tiles for ornamenting walls are very apt to get loose and fall off, and large
numbers of Patents have been taken out for modes of placing them on walls, none
of which however appear effective.
Now my Invention consists in keying the tiles into each other instead of or as
well as on the walls. My plan is to construct a projecting flange on the back part
of two edges of each tile to fit behind the one below (or above) and on one side
of it.
The backs of the tiles do not require to be roughened (though they may be) and
they are fastened to the wall with cement or otherwise. Their faces may be glazed
or ornamental in any manner desired, and the tiles made of any material from
which ornamental and enamelled tiles are manufactured.
DESCRIPTION OF DRAWINGS.
Figures 1, 2, and 3 shew plan edge view and section respectively of a tile in
accordance with my Invention.
In using these tiles I begin with the bottom or top row, luting the joints and
backs with plaster or preferably cement, course by course; I find that the flanges
give great assistance in placing the tiles all to one uniform surface, and that while
my tiles cost little or no more to make than the ordinary tiles, they require much
less cement, can be put up in much less time and by less skilful labour than is
required with the ordinary tile. They cannot cone individually loose and fall out,
as other tiles are apt to do, as each tile is supported and keyed in by the surrounding
ones; lastly, as damp has with my tiles to creep along the cemented crack between
two flanges, as well as the two sets of terminal edges, before appearing through the
tile layer, instead of as in the ordinary plan between the one set of terminal edges
only, my system will be found much more impervious to damp than the ordinary
plan and particularly applicable for external use.
Having now described my Invention and the best mode known to me of carrying
it into effect, I wish it to be understood that I make no claim whatever for tiles or
slabs made, substantially in the shape herein described, but used in conjunction
with transverse ties, and of concrete or other cheap coarse material for use in
building, and forming concrete or other walls, nor yet the use of blocks of fire-clay,
made substantially of the same shape and used in constructing the interior of
enamelling kilns, as they are totally different adaptations of the principle to mine,
but what I claim as new under the herein-before in part recited Letters Patent is,
the manufacture of tiles of earthenware, enamelled encaustic, or other similar ware,
substantially as described, constructed with flanges projecting and overlapping each
other for covering the surface of walls for the purpose of ornament, as a protection
from damp, or to reflect light.
In witness whereof, I, the said George Anthony Marsden, have hereunto
set my hand and seal, this Thirtieth day of March, in the year of our Lord
One thousand eight hundred and seventy-eight.
