An Improved Process and Means used therein for Attaching Glass
Tiles to Walls or other Structures.
I, JOHN GORDON, of 181, Sebert Road, Forest Gate, London, E., Engineer,
do hereby declare the nature of this invention to be as follows:--
My invention relates to an improved process and to means used therein for
attaching smooth glass tiles to walls or other structures so that they will firmly
adhere in spite of considerable variations of temperature or climatic influences
or moisture.
It is convenient and economical to employ cement as the main material for
surfacing walls or the faces of structures which it is required to face with glass
tiles, but smooth glass tiles will not adhere with any security upon a facing of
cement.
To effect the desideratum I prepare the under side of the glass tiles with a
special backing of a composition composed of 75% of rock asphalte such as that
of the Val de Travers and 25% of best bitumen.
To prepare the tiles they are heated to about 300° Fahr.; and a thin layer of
the above composition, when plastic or molten, is applied to them, such com-
position firmly adhering to the back of the said smooth glass tiles and having
valuable properties such as being absolutely water-proof and sufficiently refractory
to resist any ordinary climatic rises of temperature without becoming soft or
allowing the tiles to be detached.
I then heat coarse silicious sand to at least 300° F. and brush or dust it over
the surface of the said composition backing of the tiles, such sand becoming
firmly embedded into and engaging with the said composition and
affording a roughened surface which will key into and firmly adhere
to the moist cemented surface of a wall or structure, when pressed
thereon. The compound backing for the glass tiles thus prepared and
applied has several advantages. It is cheap and more economical than a complete
facing and backing of an asphaltic composition alone, the adherence of the glass
plates is very perfect and the intermediate backing of my asphaltic composition
renders the facing waterproof, and permits a certain amount of elastic movement
to the tiles, preventing splitting or cracking off of the tiles, by the action of
climatic changes, or by the bulging or settling of the main wall or structure.
Dated this 3rd day of February 1898.

page_text: An Improved Process and Means used therein for Attaching Glass
Tiles to Walls or other Structures.
I, JOHN GORDON, of 181, Sebert Road, Forest Gate, London, E., Engineer,
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 follow-
ing statement:-
My invention relates to an improved process and to means used therein for 5
attaching smooth glass tiles to walls or other structures so that they will firmly
adhere in spite of considerable variations of temperatures or, climatic. influences
or moisture.
It is convenient and economical to employ Portland or other similar cement
for the purpose of fixing tiles, but smooth glass tiles will not adhere with any
security when fixed with cement.
To effect this desideratum I prepare the under side of the glass tiles with a
special compound backing which adheres firmly to the smooth glass, is water-
proof, elastic, is not effected by climatic changes and at the same time presents
a face to ordinary cement capable of not only keeping therewith, but by its
affinity of firmly adhering thereto.
In order that this invention may be the better understood I will now proceed
to describe the same with reference to the drawings hereto annexed and to the
letters and figures marked thereon.
Figure 1 is a view of the back and
Figure 2 is a section of my improved glass tile.
A is the glass tile, B is the first backing of asphalte mastic, C are particles of
course sand embedded therein forming a receptive and adherent surface for
moist cement, mortar, or plaster D), the tile being then ready for application.
To prepare the tiles the glass is heated to about 300° F. and a thin layer of a
special asphalte composition when plastic or molten is applied to them..
The special asphalte composition or mastic I employ is composed of 75 per cent.
of rock asphalte (such as that of the Val de Travers) and 25% of best Trinidad
bitumen such composition firmly adhering to the back of the said smooth glass
tiles and having valuable properties such as being absolutely water-proof and
sufficiently refractory to resist any ordinary climatic changes of temperatur
without becoming soft or brittle or allowing the tiles to be detached.
I then apply course silicious sand heated to at least 300° F. spreading it ove
the surface of the said composition backing of the tiles; such. sand is caused t
become firmly embedded into and to engage with the said composition an
affords a roughened surface which will key into and also firmly adhere to moi
cement or even to mortar or plaster, which being spread over the prepared bac
of the tile, renders the said ready for application to any wall or surface.
The compound backing for the glass tiles thus prepared and applied h
several advantages. It is cheaper and more economical than a complete faci
and backing upon the wall or supporting surface of an asphaltic compositi
alone; the adherence of the glass plates is very perfect; and the intermedia
backing of my asphaltic composition renders the facing water-proof and perm
a certain amount of elastic movement to the tiles, preventing splitting or crac
ing off of the tiles, by the action of climatic changes, or by the bulging or settli

page_text: Having now particularly described and ascertained the nature of this in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. An improved process for the facing of walls or other structures, consisting
of the application of a backing of plastic cement or mortar to a smooth glass
tile already prepared with a set and fixed water-proof elastic backing of asphalte
composition, having an external keying facing of sand adapted to seize upon
and adhere to the said cement, and the adaptation of the said tile with its pre-
pared backing and plastic cement to the said walls or surfaces.
2nd. The manufacture of a facing tile of smooth glass consisting of the heat-
ing of the glass to about 300° Fahr.; the application thereto of an asphalte mastic
of the composition described in a plastic or molten condition of the said mastic;
the spreading on the said mastic and the embedding thereinto whilst still molten
of coarse silicious sand previously heated to about 300° Fahr.; thus assuring
firm adherence of the glass to the mastic backing and providing a roughened
surface to the latter, adherent to cement, or the like, substantially as described.
3rd. In combination; a facing tile of smooth glass; a backing thereto of
asphalte mastic, consisting of 75% of rock asphalte mixed with 25% of best
Trinidad bitumen; and an embedded layer thereon of coarse silicious sand, to
adapt said glass tile to be firmly fixed with ordinary cement on any wall or
structure, substantially as described.
