Sainte Appoline, Paris, Empire of France, for the Invention of "IM-
PROVEMENTS IN THE MANUFACTURE OF BELTS, BANDS, OR ROPES
TRANSMISSION OF POWER FOR DRIVING MACHINERY, AND
PURPOSES."

Sealed the 5th January 1869, and dated the 8th July 1868.
PROVISIONAL SPECIFICATION left by the said Armand Jules Le
. Blanc at the Office of the Commissioners of Patents, with his
. Petition, on the 8th July 1868.
I, ARMAND JULES LE BLANC, Mechanic, of 2, Rue Sainte Appoline,
Paris, Empire of France, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF BELTS, BANDS, OR ROPES FOR
THE TRANSMISSION OF POWER FOR DRIVING MACHINERY, AND FOR OTHER PURPOSES."
to be as follows:-
My Invention primarily consists in the manufacture of belts, bands,"
or ropes by means of a fabric, by preference of cotton, coated with
caoutchouc and rolled on and into one another; it is then submitted
to strong pressure in order to cause the caoutchouc to pass through and

page_text: into the pores of the fabric; the material is subsequently coated with
caoutchouc and vulcanized.
My Invention further consists in the employment for the manufacture
of belts, bands, or ropes of all kinds of woven tissues or textile fibres
or twisted, and impregnated with caoutchouc, gutta percha, or
other gummy or resinous materials, thus giving to belts, bands, or ropes
similar advantageous results that the present india-rubber and vulcanized
cotton fabric possess.
Belts, bands, or ropes made according to my Invention are excellent
substitutes for those now made of wire, with the constituent properties
directly opposite, since the new are composed of almost soft materials;
they can be used for driving metal or wood pulleys without a leather or
caoutchouc coating; they can be passed round pulleys of a very small
diameter; they are free from oxidation and dilatation, which are usual in
those made of metal; they do not make any noise while moving; they
are easily placed in position by a simple ligature, and not being liable to
break the dangers often resulting from the breaking of a wire rope is
materially diminished, while at the same time they transmit power and
motion, and may be used as belts, bands, or ropes generally.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Armand Jules Le Blanc in the Great Seal Patent
Office on the 8th January 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARMAND
JULES LE BLANC, Mechanic, of 2, Rue Ste. Appoline, Paris, Empire of
France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of July, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Armand Jules Le Blanc, Her special
licence that I, the said Armand Jules Le Blanc, my executors, admi-
nistrators, and assigns, or such others as I, the said Armand Jules Le
Blanc, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time, and at all times

page_text: 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 "IMPROVEMENTS IN THE MANUFACTURE OF BELTS, BANDS, OR ROPES FOR THE
TRANSMISSION OF POWER FOR DRIVING MACHINERY, AND FOR OTHER PURPOSES,"
upon the condition (amongst others) that I, the said Armand Jules
Le Blanc, my executors or administrators, by an instrument in writing
under my,
or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention,
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
Letters
months next and immediately after the date of the said
Patent.
NOW KNOW YE, that I, the said Armand Jules Le Blanc, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
My Invention primarily consists in the manufacture of belts, bands,
or ropes by means of a fabric, by preference of cotton, coated with
caoutchouc and rolled on and into one another; it is then submitted
to strong pressure in order to cause the caoutchouc to pass through and
into the pores of the fabric; the material is subsequently coated with
caoutchouc and vulcanized.
My Invention further consists in the employment for the manufacture
of belts, bands, or ropes of all kinds of woven tissues or textile fibres
woven or twisted, and impregnated with caoutchouc, gutta percha, or
other gummy or resinous materials, thus giving to belts, bands, or ropes
similar advantageous results that the present india-rubber and vulcanized
cotton fabric possess. They can be made of caoutchouc prepared to resist
fatty bodies with oil.
Belts, bands, or ropes made according to my Invention are excellent
substitutes for those now made of wire, with the constituent properties
directly opposite, since the new are composed of almost soft materials;
they can be used for driving metal or wood pulleys without a leather or
caoutchouc coating; they can be passed round pulleys of a very small
diameter; they are free from oxidation and dilation, which are usual in
those made of metal; they do not make any noise while moving; they
are easily placed in position by a simple ligature, or by buttons, rivets,

page_text: screws, buckles, or other fastenings, and not being liable to break the
dangers often resulting from the breaking of a wire rope is materially
diminished, while at the same time they transmit power and motion, and
may be used as belts, bands, or ropes generally.
And having now described the nature of my said Invention, for and
in what manner the same is to be performed, I declare that I claim, the
improvements in the manufacture of belts, bands, or ropes for the
transmission of power for driving machinery, and for other purposes,
all substantially as herein-before described.
In witness whereof, I, the said Armand Jules Le Blanc, have
hereunto set my hand and seal, this Thirty-first day of December,
in the year of our Lord One thousand eight hundred and sixty-
eight.
