AN IMPROVED PLASTIC COMPOSITION APPLICABLE TO MANUFACTURING PURPOSES
Year: 1852

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
GAULLIE, of Paris, France, Sculptor, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom, of Great
Britain and Ireland, bearing date at Westminster, the Sixth day of July,
One thousand eight hundred and fifty-two, in the sixteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Alfred Gaullié, my exors, admors, and assigns, Her especial license, full
power, sole privilege and authority, that I, the said Alfred Gaullié, my
exors, adiñors, and assigns, or such others as I, the said Alfred Gaullié, my
exors, admors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, and in the Islands of Jersey,
Guernsey, Alderney, Sark, and Man, and also in all Her said Majesty's
Colonies and Plantations abroad, my Invention of "AN IMPROVED PLASTIC
COMPOSITION APPLICABLE TO MANUFACTURING PURPOSES;" in which said Letters
Patent is contained a proviso that I, the said Alfred Gaullié, shall cause a
particular description of the nature of my said Invention, and in what manner

page_text: the same is to be performed, by an instrument in writing under my hand
and seal, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Alfred Gaullié, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say :-
My Invention consists in combining gutta percha in the raw state with
Roman cement by means of animal gall, and forming therewith a plastic
material capable of being stamped, moulded, and receiving all the different
shades of coloration.
I first take half by weight of gutta percha, and reduce it to a liquid state
by introducing it into a metallic vessel japanned internally, and exposing it to
the heat of fire or to the action of steam. I stir about the matter with an
iron or wooden spoon, and leave it so exposed until the gutta percha has been
reduced to a degree of liquescence suitable for the operation. I next take an
equal weight of Roman cement previously well bruised, and reduce the same
to a pasty condition by means of the gall of oxen, which I use in preference
on account of its low price, although the gall of animals in general will answer
the purpose equally as well. I mix the gutta percha and Roman cement
together, and I stir about the two substances violently while mixing them
together in order to effect a complete incorporation, and allow the matters to
cool down. In this state the composition is fit to be employed in the plastic
arts, and from its malleable and impervious qualities it may be used with
advantage to supersede caoutchouc and gutta percha in their various appli-
cations to the manufactures and to the fine arts, more especially for the
manufacture of buttons, articles of domestic use and ornament. To effect the
coloration of the said composition, I reduce the desired colors to a state of
paste by means of animal gall, in a similar manner to the Roman cement, after
which I mix them with the gutta percha as herein described; by this means
all the different shades of color are imparted to the composition.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I wish it to be understood that what I
claim as my Invention, and intend to be protected by the said Letters
Patent, is, the production of a plastic waterproof composition, susceptible of
receiving the different shades of coloration, for superseding gutta percha and

page_text: caoutchouc, alone or combined with other materials in their different appli-
cations, as herein-before described.
In witness whereof, I, the said Alfred Gaullié, have hereunto set my
hand and seal, this Third day of January, One thousand eight hundred
and fifty-three.

page_text: AND BE IT REMEMBERED, that on the oath of Henry Gilbee, the
Specification aforesaid was enrolled word for word as above written. And also
the Specification aforesaid was stamped according to the tenor of the Statute
made for that purpose.
Enrolled the Sixth day of January, in the year of our Lord One thousand
eight hundred and fifty-three.
