page_text: LETTERS PATENT to Benjamin Edouard Guyot de Bruu, residing at Pantin,
Rue d'Montreuil, 18, (Seine,) in the Empire of France, for the Invention
of LEATHER TISSUE AND OTHER TISSUES RENDERED WATERPROOF BY A NEW
PROCESS"
Sealed the 10th September 1858, and dated the 30th April 1858.
PROVISIONAL SPECIFICATION left by the said Benjamin Edouard Guyot
de Brun at the Office of the Commissioners of Patents, with his Petition,
on the 30th April 1858.
I BENJAMIN EDOUARD GUYOT DE BRUN, residing at Pantin, Rue de Mon-
treuil, 18, (Seine,) in the Empire of France, do hereby declare the nature of
the said Invention for "LEATHER TISSUE AND OTHER TISSUES RENDERED WATER-
PROOF BY A NEW PROCESS," to be as follows:-
I.take five hundred grams of linseed oil, into which I throw fifteen grams
of litharge in powder, fifteen grams of brown amber, also in powder, then two
grams of hydro-protoxide of manganese, which has been first of all subjected
to a slow fire for one hour with some linseed oil; I mix this all together,
then let it stand for some days to get clear. When I want to use this oil for
a.cotton, linen, or woollen tissue, for the first coat, I mix with the oil a nearly
equal portion of water, and beat them both together tiil they are perfectly
mixed; then; by the aid of a piece of sponge, I spread this mixture of oil &
water all over the tissue, and leave it to dry; then to this oil mixed with, but
without any more water, I put some lamp black and make a tolerable thick
[Price &d]

page_text: paste, which I spread on the tissue just spoken of by means of a little iron
scraper. If the tissue employed is thin, and it is wanted to dry quickly, the
oil mixture must be boiled from two to three hours, in order to reduce it to
the desired thickness, then immediately add fifteen grams of salts of lead to
each kilogram of the oil mixture, then some purifying essence,and lamp black
is added to form a paste, which is to serve for the second coat just spoken of.
The operation continues in all cases by fresh coats of the oil mixture not
boiled till the bottom of the tissue is well made, taking care to pounce or
polish the tissue in order to make it close and even. After this, one must stop
to make it black or some other color; if black, then lamp black must be used
mixed with oil and purifying essence, which must be put on with a brush; if
another color, then the color is mixed with oil & purifying essence; and this
mixture is also put on with a brush. When the tissue is done over with this
and dry, it is pounced slightly and varnished with the following varnish :-
One kilogram of common oil boiled about twenty-four hours with five grams
of brown umber; fives of litharge,& five grams of Prussian blue; to this
is added some purifying essence, when the oil thus composed is three parts
cold; then, when the tissue is perfectly dry, it is passed under an engraved
cylinder, in order to give it the appearance of grained neat's leather or
morocco, that is to say, if the purpose for which it is intended requires it to
have this appearance.
The tissue obtained by the process just described is waterproof, and can be
used for boots, either patent leather or not, hats, furniture, carriages, binding
of books, different parts of the dress, and other articles intended to come in
contact with water, of whatever form they may be, or of whatever use they
may be put to; it can be silver gilt, and can receive any impression by means
of engraved cylinders.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Edouard Guyot de Brun in the Great Seal Patent
Office on the 6th October 1858.

that I, the said Benjamin Edouard Guyot de Brun, my executors or adminis-

by the following statement (that is to say):-
I take five hundred parts of linseed oil, into which I throw fifteen parts of
litharge in powder, fifteen parts of brown umber, also in powder, then two
parts of hydro-protoxide of manganese, which has been first of all subjected to
a slow fire for one hour with some linseed oil. I nix this all together, then
let it stand for some days to settle. When I want to use this oil for a cotton,
linen, or woollen tissue, for the first coat, I mix with the oil a nearly equal
portion of water, and beat them both together till they are perfectly mixed;
then, by the aid of a piece of sponge, I spread this mixture of oil and water
all over the tissue,and leave it to dry; then to this oil mixed with, but without
additional water, I put some lamp black, and make a tolerable thick paste,
which I spread on the tissue just spoken of by means of a small iron scraper.
If the tissue employed is thin, and it is wanted to dry quickly, the oil mixture
must be boiled from two to three hours, in order to reduce it to the desired
thickness; then immediately add fifteen parts of salt of lead to each thousaud
parts of the oil mixture; then some turpentine and lamp black is added to
form a paste, which is to serve for the second coạt just spoken of. The
operation continues in all cases by fresh coats of the oil mixture not boiled till
the bottom of the tissue is well made, taking care to (pounce) or polish the

page_text: tissue, in order to make it close and even. After this it must be made black
or sonie 'other color; if black, then lamp black must be used mixed with oil
and turpentine, which must be put on with a brush; if another color, then
that color is mixed with oil and turpentine, and put on in the same manner
When the tissue is done over with this and dry, it is pounced slightly and
varnished with the following varnish:-One thousand parts of common oil
boiled about twenty-four hours with five parts of brown umber, five parts of
litharge, and five parts of Prussian blue; to this is added turpentine when the
oil thus composed is three parts cold. Then, when the tissue is perfectly dry,
it is passed-under an engraved cylinder, in order to give it the appearance of
grained neat's leather or morrocco, that is to say if the purpose to which it is
intended requires it to have this appearance.
'The tissue obtained by the process just described is waterproof, and can be
used for boots, either patent leather or not, for hats, furniture,carriages, book
binding, different parts of the dress, and other articles intended to come in
contact with water, of whatever form they may be, or for whatever use they
may be put to; it can be silver gilt, and can receive any impression by means
