IMPROVEMENTS IN THE MANUFACTURE OF EMBOSSED MATERIAL FOR WALL DECORATION
Year: 1878

page_text: LETTERS PATENT to John Harrington, of Ryde, in the Isle of Wight, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF EMBOSSED MATERIAL
FOR WALL DECORATION."
Sealed the 25th March 1879, and dated the 28th September 1878.
PROVISIONAL SPECIFICATION left by the said John Harrington at the Office
of the Commissioners of Patents on the 28th September 1878.
JOHN HARRINGTON, of Ryde, in the Isle of Wight. "IMPROVEMENTS IN THE
MANUFACTURE OF EMBOSSED MATERIAL FOR WALL DECORATION."
The Invention has for its object improvements in the manufacture of embossed
material for wall decoration.
Hitherto in order to preserve the raised designs in such description of embossed
material some of the larger recesses formed in the back of such material by the
embossed design have been strengthened by the application thereto of adhesive or
other strengthening material, or strips or pieces of paper have been pasted across
the principal recesses to prevent the embossed paper or other material extending or
opening out on the application of paste thereto for the purpose of hanging the same
on walls.
This process however left the back of the embossed material irregular, and in
consequence when hanging the same on walls the raised design was frequently
much damaged, distorted, and flattened, and when hung such material was liable
to injury from blows of furniture or otherwise, but by my present Invention
I obviate these inconveniences and secure the retention of the raised design in
its perfect state, whilst I obtain a suitable back to the material to enable the same
to be securely fixed to walls.

page_text: In carrying my Invention into effect I prepare a compound, say of glue, fine saw-
dust, and glycerine, and apply the same to the back of the embossed material so as
completely to fill in all the recesses in the back thereof and produce a perfectly
plane surface; over this I apply a sheet of paper which becomes firmly cemented
thereto.
Other compounds may however be employed for this purpose.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Harrington in the Great Seal Patent Office on the 28th March
1879.
JOHN HARRINGTON, of Ryde, in the Isle of Wight.
"IMPROVEMENTS IN THE
MANUFACTURE OF EMBOSSED MATERIAL FOR WALL DECORATION."
The Invention has for its object improvements in the manufacture of embossed
material for wall decoration.
Hitherto in order to preserve the raised designs in such description of embossed
material some of the larger recesses formed in the back of such material by the
embossed design have been strengthened by the application thereto of adhesive or
other strengthening material, or strips or pieces of paper have been pasted across
the principal recesses to prevent the embossed paper or other material extending or
opening out on the application of paste thereto for the purpose of hanging the same
on walls.
This process however left the back of the embossed material irregular, and in
consequence during the process of hanging the same on walls the raised design was
frequently much damaged, distorted, and flattened, and when hung such material
was liable to injury from blows of furniture or otherwise, but by my present Inven-
tion I obviate these inconveniences and secure the retention of the raised design in
its perfect state whilst I obtain a suitable continuous back to the material to enable
the same to be securely fixed to walls.
In carrying my Invention into effect I fill in the hollows or recesses in the back
of stamped papers or other embossed material for wall decoration with any suitable
material in such a way that the whole of the embossed work shall be supported by
a backing which shall prevent the embossed work from becoming depressed either
by the application of paste or glue to the back, or by any injury it might receive on
the face of the design, and so that when finished the back of the stamped material
shall have a uniform or approximately uniform surface.
The composition I prefer to use for this purpose is made in the following way:-
I dissolve about four pounds of common glue in about two pounds of water, and
when dissolved I add thereto about twelve ounces of crude glycerine, pouring and
stirring gently while the glue is on the fire; I also add in the same way about
twelve ounces of raw linseed oil. When the above is well mixed I add about two
and a half pints of fine sawdust or paper pulp, stirring it in gently.

page_text: While the composition is warm I place the embossed material with its face down-
wards on a bench or table, I then float the composition over the back and scrape or
strike off by means of a straight edge or scraper all that portion of it which projects
beyond the surface of the back of the embossed material. While the composition is
still warm I place sheets or continuous lengths of paper over the level surface which
will adhere to it from the adhesive character of the composition and thus form a
level backing.
Other suitable compounds or materials may however be employed for this
purpose.
Having thus described the nature of my said Invention and the mode in which I
carry the same into effect, I would have it understood that what I claim is, the
improvements in the manufacture of embossed material for wall decoration, sub-
stantially as and for the purpose herein described.
In witness whereof, I, the said John Harrington, have hereunto set my
hand and seal, this Thirteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
JOHN HARKINGTON. (L.S.)
