IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL PROAL
Year: 1881

page_text: LETTERS PATENT to Frederick Charles Jeune, of 59, Queen Victoria Street,
in the City of London, Managing Director of Jeune and Company, Limited,
for an Invention of "IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL
PROVISIONAL SPECIFICATION left by the said Frederick Charles Jeune
at the Office of the Commissioners of Patents on the 13th May 1881.
FREDERICK CHARLES JEUNE, of 59, Queen Victoria Street, in the City of
London, Managing Director of Jeune and Company, Limited. "IMPROVEMENTS IN
THE MANUFACTURE OF ORNAMENTAL EMBOSSED FABRICS FOR COVERING WALLS,
AND FOR LIKE USES."
This Invention has for its object improvements in the manufacture of ornamental
embossed fabrics for covering walls, and for like uses.
For these purposes a composition is first prepared consisting of india rubber and
cork similar to but finer than that made use of in the manufacture of cork carpet.
Raw or native india rubber is thoroughly cleansed by means of washing rollers,
and is placed in a stove and dried; it is reduced then to a body in a machine
known as a masticator. After this treatment the india rubber is rolled finely out
into sheets, and it is converted into dough by the aid of a spirit solvent. The
dough is mixed in a mixing machine with about an equal quantity of very finely
ground cork, and the dough is spread by means of rollers in a thin layer on one or
both sides of a cotton or other fabric. The length when completed is put into a
drying room, afterwards the fabric is passed several times between calender rolls,
and then is faced by grinding upon a revolving stone in a facing machine. The
fabric is now ready for embossing; the embossing is performed by flat pressure
between a block having the desired pattern sunk into its surface, and a pad or
force on the other side. A considerable pressure is used, and the fabric takes and
retains the embossing sharply and well.
The different parts of the pattern are colored by hand or otherwise, the better to
bring out the design, and finally the surface is varnished.
By these means close imitations of embossed leather can be produced; carved
wood can also be imitated in this manner.

FREDERICK CHARLES JEUNE, of 59, Queen Victoria Street, in the City of

This Invention has for its object improvements in the manufacture of ornamental

For these purposes a composition is first prepared consisting of india rubber and
cork similar to but finer than that made use of in the manufacture of cork carpet.
Raw or native india rubber is thoroughly cleansed by means of washing rollers,
and is placed in a stove and dried; it is reduced then to a body in a machine
known as a masticator. After this treatment the india rubber is rolled finely out
into sheets, and it is converted into dough by the aid of a spirit solvent. The
dough is mixed in a mixing machine with about an equal quantity of very finely
ground cork, and the dough is spread by means of rollers in a thin layer on one or
both sides of a cotton or other fabric. The length when completed is put into a
drying room, afterwards the fabric is passed several times between calendar rolls,
and then is faced by grinding upon a revolving stone in a facing machine. The
fabric is now ready for embossing; the embossing is performed by flat pressure
between a block, having the desired pattern sunk into its surface, and a pad or
force on the other side. A considerable pressure is used, and the fabric takes and
retains the embossing sharply and well.
The different parts of the pattern are colored by hand or otherwise, the better to
bring out the design, and finally the surface is varnished.
By these means close imitations of embossed leather can be produced, carved
wood can also be imitated in this manner.
In practically carrying out my Invention I proceed as follows:-
In the first place I obtain fine white cork shavings, which are carefully sorted so
that no dark or barky pieces remain; this is then ground by the aid of millstones
and passed through fine sieves, so that the grains are obtained of uniform size. In
the next place the india rubber is first crushed through rollers and washed perfectly
clean and dried; it is then masticated and afterwards rolled out into thin sheets, as
above explained, and when thoroughly dried is reduced to dough with solvent
spirit. I use about 15 gallons of spirit to 30 lbs. of india rubber; about equal
portions of ground cork and dough are next placed in a mixing machine, and when
thoroughly mixed the compound produced is spread upon one or both sides of a
fine cotton fabric (as required); the cloth is then several times callendered; after
this the cloth is faced by a machine for that purpose, as above described; it is then
trimmed and cut into the requisite widths, and is now ready for the process of
embossing and tinting.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I claim, the manufacture of
ornamental embossed fabrics for covering walls, and for like uses, substantially in
the manner herein before described.
In witness whereof, I, the said Frederick Charles Jeune, have hereunto set
my hand and seal, this Eleventh day of November, in the year of our Lord
One thousand eight hundred and eighty one.
