Year: 1874

page_text: LETTERS PATENT to Ange Courbier and Ernest-Noël Villalard, the
younger, both of Bordeaux, in the Republic of France, for the
Invention of "IMPROVEMENTS IN DRIVING BANDS AND BELTING FOR
MACHINERY." A communication from Louis Gustave Sourzac, of
Bordeaux, aforesaid.
Sealed the 16th February 1875, and dated the 9th September 1874.
PROVISIONAL SPECIFICATION left by the said Ange Courbier and
Ernest Noël Villalard at the Office of the Commissioners of Patents,
with their Petition, on the 9th September 1874.
We, ANGE COURBIER and ERNEST-NOËL VILLALARD, the younger, both
of Bordeaux, in the Republic of France, do hereby declare the naturo
of the said Invention for "IMPROVEMENTS IN DRIVING BANDS AND BELTING
FOR MACHINERY," to be as follows, that is to say :—
The object of this Invention is to increase the strength and durability
of driving bands and belting for machinery, and consists in covering the
strip of leather from which a driving band is to be made with one or

page_text: more strips of webbing superposed thereon, and made wholly or in part
of hemp or other suitable vegetable, animal, mineral, or metallic textile
material, and if required in adding to these strips one or more strips of
wire gauze; or I add rope made of metal or of the same material as the
above described strips of webbing in suitable proportion. The uniting
together of these various parts may be effected, either by means of rivets,
pins, screws, nails, pegs, or seams. If desired these several strips and
ropes as well as the leather strip may be coated with linseed oil litharged
or not, and with or without admixture with other suitable materials.
These strips and ropes may be submitted either together or separately to
the degree of tension necessary to lessen or prevent their elongation
from the effect of wear.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ange Courbier and Ernest Noel Villalard in the ]
Great Seal Patent Office on the 8th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ANGE
COURBIER and ERNEST NOEL VILLALARD, the younger, both of
Bordeaux, in the Republic of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of September, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Ange Courbier and Ernest
Noel Villalard, Her special license that we, the said Ange Courbier and
Ernest Noel Villalard, our executors, administrators, and assigns, or
such others as we, the said Ange Courbier and Ernest Noel Villard,
our 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
"IMPROVEMENTS IN DRIVING BANDS AND BELTING FOR MACHINERY," com-

page_text: municated to us by Louis Gustave Sourzac, of Bordeaux, aforesaid, upon
the condition (amongst others) that we, the said Ange Courbier and
Ernest Noel Villalard, our executors or administrators, by an instrument
in writing under our or their, or one of their hands and seals, should
particularly 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
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Ange Courbier and Ernest Noel
Villalard, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement: —
The Invention relates to increasing the strength and durability of
driving bands, and consists in covering the leather band or belt or fixing
thereon one or several bands more or less strong, composed wholly or
partially without regard to shape or form of hemp or any other material,
either textile, vegetable, animal, mineral, or metallic, and if required in
adding to these bands one or several bands of metallic tissue, or cords of
metal, or of the same material as those above mentioned of whatever
size and strength is thought suitable. These stiffeners and bands are
connected together by means of rivets, bolts, screws, nails, pegs, pins, or
stitching of any kind whatever. These different bands and cords may if
desired together with the leather band be coated with lineseed or other
oil containing litharge or not, and with or without the addition of any
other matter tending to improve this composition. These bands or
cords may be made to undergo a degree of tension which experience will
determine in order to prevent their being drawn out in use.
The Invention may be applied equally as well to new as to worn
bands.
Having thus described the nature of the said improvements and the
manner of carrying them into effect, we would have it understood that
we do not confine ourselves to the precise details above enumerated, as
these may obviously be modified without departing from the principle of
claim is driving hands and holting

page_text: machinery consisting of leather bands strengthened by means of
stiffeners, substantially as above described.
In witness whereof, we, the said Ange Courbier and Ernest Noel
Villalard, have hereto set our hand and seal, this Fifth day of
March, in the year of our Lord One thousand eight hundred and 5
seventy-five.
A. COURBIER. (L.S.) E. N. VILLALARD.
