page_text: LETTERS PATENT to Emile Georges Fermier de la Provotais, of 29,
Boulevart St. Martin, Paris, for the Invention of "EXTRACTING THE
FIBRES FROM GENISTA SCOPARIA (BROOM), AND THEIR APPLICATION TO MANU-
FACTURING PAPER AND FABRICS, AND ALSO TREATING THE WASHING WATERS SO
AS TO OBTAIN DYEING PRODUCTS THEREFROM."
Sealed the 7th January 1862, and dated the 15th July 1861.
PROVISIONAL SPECIFICATION left by the said Emile Georges Fermier
de la Provotais at the Office of the Commissioners of Patents, with
his Petition, on the 15th July 1861.
I, EMILE GEORGES FERMIER DE LA PROVOTAIS, of 29, Boulevart St. Martin,
Paris, do hereby declare the nature of the said Invention for EXTRACTING THE
FIBRES FROM GENISTA SCOPARIA (BROOM), AND THEIR APPLICATION TO MANUFACTURING
PAPER AND FABRICS, AND ALSO TREATING THE WASHING WATERS SO AS TO OBTAIN
DYEING PRODUCTS THEREFROM," to be as follows:-
My Invention relates to the treatment of all kinds of broom (genista
scoparia) for the purpose of obtaining, 1st, ligneous fibres suitable for the
manufacture of paper, or for conversion into fabrics; 2ndly, of obtaining
coloring matters from the washing waters remaining after the treatment of
the fibres.
The following is the method of preparing the fibres of the broom :-I first
collect the broom; 2ndly, steep it in water heated with steam: 3rdly, bark
or decorticate it by passing it between stone cylinders; 4thly, I mechanically
separate the fibres from the ligneous part, &, 5thly, treat the ligneous fibres
to convert them into threads similar to hemp or flax threads.
To prepare the broom for conversion into paper pulp, I first treat it in the

page_text: manner above described; and after removing the bark, I 4thly, wash it in
plenty of water; 5thly, boil it in water heated with steam; 6thly, treat it
with alkalies or alkaline carbonates; 7thly, wash it in water, & 8thly, I
treat it with chlorine or hypochlorites. It is then ready for use in the
manufacture of paper.
The washing waters which contain resinous & anummy matters Itne
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Emile Georges Fermier de la Provotais in the Great Seal
Patent Office on the 14th January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EMILE
GEORGES FERMIER DE LA PROVOTAIS, of 29, Boulevart St. Martin, Paris,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Emile Georges Fermier de la Provotais, Her special licence that I,
the said Emile Georges Fermier de la Provotais, ny executors, adminis-
trators, and assigns, or such others as I, the said Emile Georges Fermier de
la Provotais, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
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 Isle of Man, an Invention for "EXTRACTING THE
FIBRES FROM GENISTA SCOPARIA (BROOM), AND THEIR APPLICATION TO MANUFACTURING
PAPER AND FABRICS, AND ALSO TREATING THE WASHING WATERS SO AS TO OBTAIN
DYEING PRODUCTS THEREFROM," upon the condition (amongst others) that I, the
said Emile Georges Fermier de la Provotais, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, 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 Emile Georges Fermier de la Provotais,
de hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say:-
My Invention relates to the treatment of all kinds of broom (genista
scoparia) for the purpose of obtaining, 1rst, ligneous fibres suitable for the
manufacture of paper, pasteboard, or fibres intended to be converted into
fabrics; 2dly, obtaining coloring matters from the washing waters remain-
ing after the treatment of the fibres.
The treatment of broom for the purpose of preparing the fibres consists
of several operations, viz., the collecting of the broom; its hasty retting in
water heated by steam; its barking or decortication by being passed between
hard stone cylinders; the separation of the fibrous from the ligneous part;
the treatment of the ligneous part for its conversion into threads similar to
hemp or flax threads.
The following is the method of preparing the pulp; -1rst, collecting the
broom; 2dly, its water retting; 3dly, its barking or decortication; 4thly
its washing in running water; 5thly, its boiling in water heated by steam;
6thly, its treatment by alkalies or alkaline carbonates; 7thly, its washing
in water; Sthly, its treatment by chlorine or hypochlorites. After which
operations the pulp is ready for use in the manufacture of paper.
By treating the washing waters which contain gummy resinous matters,
I obtain picric acid and other coloring products, and also salts, with which
I produce green and yellow colors.
Having thus described the nature of my Invention, and the manner in
which the same is to be carried into effect, I wish it to be distinctly under-
stood, that what I claim as being of my Invention is,-
First, preparing ligneous fibres from genista scoparia (broom), for the
manufacture of paper, pasteboard, and also of fibres intended to be con-
verted into fabrics.
Secondly, coloring products from the washing waters remaining after the
treatment of the fibres.
In witness whereof, I, the said Emile Georges Fermier de la Provotais,
have herein set my hand and seal, this Ninth day of January, in
the year of our Lord One thousand eight hundred and sixty-two.
(L.S.) E. G. FERMIER DE LA PROVOTAIS.
