Year: 1853

page_text: LETTERS PATENT to Henri Joseph Scoutetten, of Metz, in the
Empire of France, and of 16, Castle Street, Holborn, City,
London, for the Invention of "AN IMPROVED PLASTIC COMPOUND,
ANDERALDED TO TADIONS ORSTARTERETAY AND HOBBIT PURPOSES"
PROVISIONAL SPECIFICATION left by the said Henri Joseph
Scoutetten at the Office of the Commissioners of Patents, with
his Petition, on the 21st May 1853.
I, HENRI JOSEPH SCOUTETTEN, of Metz, in the Empire of France,
and of 16, Castle Street, Holborn, City, London, do hereby declare
the nature of the said Invention for "AN IMPROVED PLASTIC COMPOUND,
APPLICABLE TO VARIOUS USEFUL AND ORNAMENTAL PURPOSES" to be as
follows, viz. :-
Composition-Bituminous substance, vegetable and mineral, enter
into the composition of this paste. 1st. Asphalte, 10 parts. Caoutchouc,
10 parts. Gutta percha, 8 parts. Turpentine, 1 part. Zinc white, 4
parts. Gum lac, 2 parts. Wax, 2 parts. Oxyde of iron, sulphur of
antimony, ultra marine, chrome yellow, or other metallic oxydes, to
color the paste, or to give it solidity.

page_text: Apparatus for making the paste :-
1st. A steam engine to furnish steam, which is forced into two hollow
cylinders, and which are moved by the aid of steam.
2nd Of a boiler filled with water, heated by the introduction of steam.
and used for softening the paste.
3rd. Of a press for compressing the paste put into moulds.
4th. Of a screw forcing a plug into a cylinder, and which drives the
paste into other smaller cylinders, having a central rod: this machine
is used for making pipes of all lengths and thicknesses, the stems of
pipes, probes, &c.
5th. Of moulds of all kinds for making articles in relief.
To compose the paste:-The asphalte is melted in a copper vase;
when sufficiently fused, the caoutchouc, dissolved in turpentine, is
added and worked up, and-then passed- between-laminating cylinders;
then the gutta percha is added, then the turpentine, gum lac; these
materials are well mixed by passing them frequently under the cylinders.
When the mixture is well made, add the metallic oxydes, which
vary according to the odour required; indeed, a metallic appearance
can be given to the material by covering the surface with a bronze
powder or other substance.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henri Joseph Scoutétten in the Great Seal Patent
Office, on the 21st November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRI JOSEPH SCOUTETTEN, of Metz, in the Empire of France, and of
16, Castle Street, Holborn (City), London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of May, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did; for Herself, Her heirs and successors,
give and grant unto me,. the said Henri Joseph Scoutetten, Her special
licence that I, the said-Henri Joseph Scoutetten, my executors, admi-
nistrators, and assigns, or such others as I, the said Henri Joseph

page_text: Scoutetten, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make
use, exercise, and vend, within the United Kingdom of Great Britain,
and Ireland, the Channel Islands, and the Isle of Man, an Inven-
tion for "AN IMPROVED PLASTIC COMPOUND APPLICABLE TO VARIOUS ORNA-
MENTAL AND USEFUL PURPOSES," upon the condition (amongst others) that
I, the said Henri Joseph Scoutetten, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
.
NOW KNOW YE, that I, the said Henri Joseph Scoutetten, lo
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to-be-particularly described and ascer-
tained in and by the following statement (that is to say):
This paste is composed of vegetable and mineral substances; the
number and quantity of each varies according to the purpose for which
the material is required. Thus, gutta percha, caoutchouc, pitch, resin,
wax, gum lac, oxyde of iron, golden sulphur of antimony, ultra marine,
chrome, zinc white, &c.
Manufacture of the Paste -A steam engine serves to furnish
steam to two superposed hollow cylinders. These cylinders are them-
selves moved by the steam, crush the substances which enter into
the composition of the paste, and form a homogeneous mass.. Double
bottomed cauldrons, equally licated by steam, receive the matter,
which, according to circumstances, may be heated dry or in hot water.
When the paste is made it is put into moulds and compressed, in
order to produce the objects required. These moulds are composed
of gutta percha containing a twentieth part of caoutchouc ; this
process of moulding affords results hitherto unknown. Each mould
should be bound with iron. This paste may also be composed chemi-
cally. In this case the gutta percha, caoutchouc, and pitch are
dissolved in sulphuret of carbon. When the solution" is complete
and the combination well effected, the solution is purified, the sulphu-

page_text: ret of carbon is drawn off, and a mass is obtained, which may be heated
dry in close vessels. If it be desired to make pipes, boot soles, straps,
&c., add to the above substances, held in solution in the sulphuret of
carbon, carded cotton, all the portions of which are penetrated or exactly
coated with the material. It is then purified, as in the former case, and
a mass is obtained, which is heated dry and passed under rollers.
Under other circumstances, and according to known processes, the
cotton is replaced by linen, canvas, silk, wool, or any other textile
substance. The paste thus prepared may be colored by adding one
or more of the oxydes indicated. When it is desired to render paper
or stuffs impermeable, the caoutchouc and the gutta percha must be
separately, dissolved in sulphuret of carbon, in the proportion of eight of
of gutta percha for one hundred of sulphuret of carbon, well purified;
the solution is left to rest during eight days, and the white of eggs is
added to it; when the impure matters are deposited it is poured forth
to obtain an almost colorless liquid. Paper or stuff may be then
steeped in this liquid, and drawn from it by passing them between
cleansing rollers, which equalize the layer of the matter. These stuffs
become fit for all impermeable clothing. The paper rendered imper-
meable is suitable for photography; it is a substitute for parchment;
it serves for the preservation of valuable papers, to prevent their falsi-
fication, erasures, and the action of chemical agents. As to the
applications of the paste, they are innumerable; they comprise a
complete moulding material, either for objects of art or utility, and
in many cases may replace leather, pasteboard, plaster, carvings in
wood, &c. The objects may be bronzed, gilt, or silvered.
In witness whereof, I, the said Henri Joseph Scoutetten, have
hereunto set my hand and seal, this Eighteenth day of No-
vember, in the year of our Lord One thousand eight hundred
and fifty-three.
