page_text: LETTERS PATENT to Charles Poirson, of No. 124, Stamford Street, in the
County of Surrey, Embroidery Manufacturer, for an Invention of "IMPROVE-
MENTS IN THE METHOD OF AND COMPOSITIONS FOR TRANSFERRING ORNAMENTAL.
AND EMBROIDERY DESIGNS TO WOVEN FABRICS, LEATHER, Wood, POTTERY,
OR ANY OTHER SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Charles Poirson at the
Office of the Commissioners of Patents on the 2nd February 1881.
CHARLES POIRSON, of No. 124, Stamford Street, London, in the County of
Surrey, Embroidery Manufacturer. "IMPROVEMENTS IN THE METHOD OF AND
COMPOSITIONS FOR TRANSFERRING ORNAMENTAL AND EMBROIDERY DESIGNS TO
WOVEN FABRICS, LEATHER, WOOD, POTTERY, OR ANY OTHER SUBSTANCES."
It is customary to transfer ornamental and embroidery designs to woven fabrics
by the application of heat at the back of such ornamental and embroidery designs,
which designs are printed by different well known processes in substances com-
pounded of bitumen or varnish, and such substances are melted on the fabrics by
the application of heat in the process of transferring.
My Invention consists in the employment of chemically combined substances,
which, when printed on paper by the different wellknown processes, such prints
are transferable to woven fabrics, leather, wood, pottery, and other materials by
the application of moisture at the back of the said printed designs, and the moisture
to be applied by sponging the back of the printed design with water, or causing
water to be spread or absorbed on the back of the paper by any means except that
of floating the printed designs on water.
.I claim as my Invention the combination of chemical salts and organic bodies,
which are to produce a liquid to be used as a printing ink or varnish, and having
the property to dissolve in water.
To obtain such a liquid I may use either the molasses or treacles, syrups, honey,
glucose, mixed together or separately, combined with any of the numerous chemical

page_text: salts which have the property to melt in their own water of crystallisation, such
as the carbonate, sulphate, hypo-sulphate of sodium or alum.
As a body-giving substances I use sugar crystallised, or uncrystallisable sugar,
or any of the sugars appertaining to that class of substances known to be susceptible
of vinous fermentation.
As a body giving substances I also use the gums known to dissolve in water,
and also dextrine, starch, and flour.
I also use citric, oxalic, malic acid, or any of that class of acid the property of
which is known to either thin down the thick solutions of sugars, or to render the
fermentible sugar uncrystallisable.
To produce the transferable ink by water I melt 100 grammes of carbonate of
sodium in its own water of crystallisation in a glass or earthenware vessel, the
heat must not exceed 170 degrees Fahrenheit. In the melted carbonate of sodium
I add 80 grammes of molasses, syrup of squills, or glucose, or else 20 grammes of
each of molasses, syrup of squills, and glucose or honey. By gently stirring the
carbonate of sodium the above named substances mix well together, and they
combine in such a manner that the carbonate of sodium loses its power of
recrystallising.
In the above liquid I dissolve 80 grammes of crystallised sugar finely ground,
and 20 grammes of dextrine or gum arabic also finely ground, the sugar and the
dextrine or gum being previously well mixed together.
I now add 5 grammes of citric acid, and when dissolved in the above solution I
leave the whole for one hour under the influence of heat not above 180 degrees
Fahrenheit.
When cold, ths addition of pigments is to be made to suit the requirements of
printing.
Having stated the different chemical salts and organic bodies that I may use in
different combinations and proportions, I claim the protection of such chemical
combinations to produce a liquid well suited to be used as an ink, with suitable
pigments or colouring matters for printing upon paper, and such prints to be
transferred by the application of water at the back of the said prints to woven
fabrics, leather, wood, pottery, and all other substances.

the said Charles Poirson in the Great Seal Patent Office on the 27th July
1881.
CHARLES POIRSON, of No. 124, Stamford Street, London, in the County of
Surrey, Embroidery Manufacturer. "IMPROVEMENTS IN THE METHOD OF AND

It is customary to transfer ornamental and embroidery designs to woven fabrics
by the application of heat at the back of such ornamental and embroidery designs,
which designs are printed by different well known processes in substances coin-
pounded of bitumen or varnish, and such substances are melted on the fabrics by
the application of heat in the process of transferring. My Invention consists in the
employment of chemically combined substances, which when printed on paper by
the different well known processes, such prints are transferable to woven fabrics,
leather, wood, pottery, and other materials by the application of moisture at the
back of the said printed designs, and the moisture to be applied by sponging the
back of the printed design with water, or causing water to be spread or absorbed
on the back of the paper by any means except that of floating the printed designs on
water. I claim as my Invention the combination of chemical salts and organic
bodies which are to produce a liquid to be used as a printing ink or varnish, and
having the property to dissolve in water. To obtain such a liquid I may use either
the molasses or treacles, syrups, honey, glucose, mixed together or separately, com-
bined with any of the numerous chemical salts which have the property to melt in
their own water of crystallisation, such as the carbonate, sulphate, hyposulphate of
sodium or alum. As body-giving substances I use sugar, crystallised or
uncrystallisable, or any of the sugars appertaining to that class of substances known
to be susceptible of vinous fermentation. As body-giving substances 1 also use the
gums known to dissolve in water, and also dextrine, starch, and flour. I also use
citric, oxalic, malic acid, or any of that class of acid, the property of which is known
to either thin down the thick solutions of sugars or to render the fermentible sugar
uncrystallisable. To produce the liquid to be used as a printing ink for trans-
ferring purposes, it is necessary to proceed thus:-One hundred grammes of
carbonate of sodium are melted in a water bath, to which is added four drahms of
nitric, hydrochloric, or sulphuric acid, separately or combined, or thirty grammes of
citric acid, or any of the vegetal acids the properties of which have been stated
before. These mineral and vegetal acids being required to prevent the recrystal-
lisation of the carbonate of sodium and sugars, I may employ for the same purpose
the molasses or treacles, the compound syrups, honey, or liquid glucose in the
proportion of four liquid drahms to every hundred parts of melted carbonate of
sodium. When the above are melted or combined seventy grammes of crystallised
sugar are to be added, or fifty grammes of crystallised sugar mixed with twenty
grammes of gum arabic or twenty grammes of dextrine, with the same quantity of
sugar. These melted substances are to be heated in the water bath, the heat not to
exceed one hundred and seventy degrees Fahrenheit.
Having stated the different chemical salts and organic bodies that I may use in
different combinations and proportions, I claim,―
The protection of such chemical combination to produce a liquid well suited to be

page_text: used as an ink, with suitable pigments or colouring matters for printing upon paper,
and such prints to be transferred by the application of water at the back of the said
prints.
In witness whereof, I, the said Charles Poirson, have hereunto set my
hand and seal, this 27th day of July, in the year of our Lord One thousand
eight hundred and eighty one.
