IMPROVEMENTS IN THE PRODUCTION OF ORNAMENTAL AND OTHER DESIGNS UPON WATERPROOF FABRICS
Year: 1883

page_text: LETTERS PATENT to Charles Moseley of the City of Manchester, in the County
of Lancaster for an Invention of IMPROVEMENTS IN THE PRODUCTION OF
ORNAMENTAL AND OTHER DESIGNS UPON WATERPROOF FABRICS
PROVISIONAL SPECIFICATION left by the said Charles Moseley at the
Office of the Commissioners of Patents on the 2nd November 1883.
CHARLES MOSELEY, of the City of Manchester in the County of Lancaster,
"IMPROVEMENTS IN THE PRODUCTION OF ORNAMENTAL AND OTHER DESIGNS UPON
WATERPROOF FABRICS"
These improvements relate to textile and other fabrics rendered waterproof by.
a coating of india rubber and subsequently coated or covered with farina or other
substance capable of creating a like effect and consist in producing an ornamental'
or other design upon the coated surface either before or during the process of
vulcanisation.
If the design is to be produced before vulcanisation I imprint it in colours upon
the surface of the farina coated fabric by suitable means, such for example as those
employed in calico printing, after which the rubber is vulcanised by the well known
cold vulcanising process.
I may also produce designs during the cold vulcanisation by engraving the roller.
used in that process when, according to the depth and form of the engraving thero
will be produced upon the surface of the coated rubber as it passes over the
roller, lighter and darker shades corresponding to the design engraved on tho
vulcanising roller.

an Order of the Lord Chancellor, filed by the said Charles Moseloy in the
Patent Office on the 30th May 1884.
CHARLES MOSELEY of the City of Manchester in the County of Lancaster
"IMPROVEMENTS IN THE PRODUCTION OF ORNAMENTAL AND OTHER DESIGNS UPON
WATERPROOF FABRICS
"
These improvements relate to Textile and other fabrics rendered waterproof
by a coating of india rubber of any desired colour or colours and subsequently
covered or treated with Farina and consist in producing an ornamental or other
design upon the coated surface either before or during the process of vulcanization.
Waterproof textile fabrics with a peculiar gloss or silky appearance have for some
time past been manufactured by the application of Farina to the surface of the
fabric. By my invention ornamental designs in differing shades or colours may
be produced by varying the silky appearance or producing it upon portions only of
the fabric.
If the design is to be produced before vulcanization I imprint it upon the farina
covered fabric by any suitable means such for example as those employed in
printing calico and other fabrics-The farina coated fabric so printed is then
vulcanized by the cold vulcanizing process-Colours may be used for printing the
design such as dyes or pigment colours and they should be mixed with or dissolved
in suitable media which will combine with, temporarily soften or otherwise act
upon the surface of the india rubber so as to cause the colour to adhere thereto or
combine therewith and which may also protect the underlying surfaces from the
action of the vapours used in the vulcanizing process-Among such suitablo media
are chloroform, benzole and its homologues, drying oils linseed oil varnish and the
like-When it is desirable to give additional body or consistency to the medium
there may be dissolved therein or mixed therewith a solid hydrocarbon such as
paraffin india rubber or any suitable gums or resins,
In carrying out this part of my invention I use rollers blocks or equivalent
printing surfaces engraved with or otherwise having formed thereupon the desired
design and I employ those rollers or blocks for printing the designs in the same
manner and by means of similar machines to those adopted or employed in
printing calico or paper hangings or in typographic printing or I may employ any
other convenient and suitable method of printing-I prefer that porion of the
engraved printing surface to be in relief which corresponds to that portion of the
design which is to be in contrast with the farina-coated surface left unacted upon
by the printing operation. When the design is desired to be in the ground colour
of the coated fabric I may obtain that colour or effect by employing the printing
medium alone without the admixture of any colour therewith. The medium will
then act as a mask or protective agent during the period in which the vapour of
chloride of sulphur and bisulpide of carbon are being applied in the vulcanizing
process.
In the vulcanizing process those portions of the farina coating which have been'
untouched in the printing operation and therefore remain in their original condition
are fixed by being subjected to the action of the vapours of a solution of chloride of
sulphur in bisulphide of carbon or other solvent and thus have their bloom or
lustrous appearance rendered permanent.
The coated fabric may afterwards be additionally vulcanized by the contact
of its coated surface in passing over a plain roller revolving in the vulcanizing
solution.

page_text: I may also produce designs during the process of vulcanization by the following
method The design which it is desired to produce upon the fabric is engraved or
otherwise formed upon the surface of a roller and this roller is made to revolve in
the vulcanizing solution in contact with the india rubber coated surface of the
fabric before or after the application of the farina-If contact is made with tho
roller before the application of the farina I apply the farina immediately thereafter
and whilst those parts of the rubber coating which have been in contact with the
relief parts of the roller are still tacky or adhesive thereby producing thereon a
design corresponding to that on the roller-If contact is made with the roller after
the application of the farina then according to the form of the design upon the
roller there will be produced upon the surface of the farina coated fabric as it passes
over the roller a design in lighter and darker shares corresponding to the design
engraved or otherwise formed upon the vulcanizing roller.
In passing over the roller those parts of the farina coating which do not come
into contact with the roller are fixed by the vapour of the solution of chloride of
sulphur in bisulphide of carbon as herein before described while those portions of the
coating which come into contact with the roller are permanently altered―The
fabric may afterwards be additionally vulcanized by passing it over and in contact
with a plain roller revolving in the vulcanizing solution.
I prefer to produce foliated and other intricate ornamental designs by the
printing process before vulcanization as hereinbefore described. Stripes and similar
open designs may be produced by the roller process during vulcanization.
Having thus described the nature of this my said invention and the best means
known to me for carrying the same into practical effect, I desire it to be understood
that I do not limit myself to the precise details as these may be varied without
departing therefrom but that what I claim as my invention is the production of
ornamental or other designs upon waterproof fabrics by the methods or processes
substantially as herein before set forth.
In witness whereof I the said Charles Moseley have hereunto set my hand
and seal this fifteenth day of May in the year of our Lord one thousand eight
hundred and eighty four.
