IMPROVEMENTS IN THE MANUFACTURE OF BANDS AND STRAPS FOR MACHINERY AND FOR OTHER SIMILAR USES."
Year: 1871

page_text: LETTERS PATENT to Jean Baptiste Colnot, of Rouen, France, Currier,
for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF BANDS
AND STRAPS FOR MACHINERY AND FOR OTHER SIMILAR USES."
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Colnot at
the Office of the Commissioners of Patents, with his Petition, on
the 16th November 1871.
I, JEAN BAPTISTE COLNOT, of Rouen, France, Currier, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF BANDS AND STRAPS FOR MACHINERY AND FOR OTHER SIMILAR
USES," to be as follows:-
Bands and straps when composed entirely of leather have been found
to become impaired by their elongation under tension, and when applied
to the transmission of motion to different parts of machinery to cause
variations of speed therein.

page_text: Now my Invention consists in combining or incorporating cotton
or woollen fabric with leather in the manufacture of bands and straps,
in order to counteract their ordinary liability to stretch lengthwise
when in use.
For this purpose the bands or straps are composed of fillets or layers
of leather and fabric united either by means of a strong adhesive
substance, such as glue, or by sewing, or both, and consolidated if
required by hand or mechanical pressure, so as to form bands or
straps.
In some cases the required thickness of the band or strap will be 1
produced by alternate fillets or layers of leather and fabric, and in
other cases by fillets or layers of fabric between two external fillets of
leather.
When the bands or straps are required to be of considerable width,
they will be made by uniting two or more fillets or layers laterally; and 1
when the bands or straps are required to be narrow, they can be cut from
wider bands or straps.
Bands or straps manufactured as above described are applicable for
use in machinery, and also for other uses in which it is desirable to
counteract the ordinary tendency of leather straps to elongate by 2
tension.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jean Baptiste Colnot in the Great Seal Patent
Office on the 15th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE COLNOT, of Rouen, France, Currier, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jean Baptiste Colnot, Her special licence that
I, the said Jean Baptiste Colnot, my executors, administrators, and assigns,
or such others as I, the said Jean Baptiste Colnot, my executors, adminis-

page_text: trators, 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 THE MANU-
FACTURE OF BANDS AND STRAPS FOR MACHINERY AND FOR OTHER SIMILAR USES,"
upon the condition (amongst others) that I, the said Jean Baptiste Colnot,
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 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 I, the said Jean Baptiste Colnot, do hereby
5 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 (that is to say) :-
My Invention of "Improvements in the Manufacture of Bands and
Straps for Machinery and for other similar Uses" has for its object the
removal of the defects herein-after referred to in bands and straps as
hitherto manufactured.
Bands and straps when composed entirely of leather have been found
to become impaired by their elongation under tension, and when applied
to the transmission of motion to different parts of machinery have been
5 found to cause variations of speed therein.
Now my Invention consists in combining or incorporating cotton or
woollen fabric with leather in the manufacture of bands and straps, in
order to counteract their ordinary liability to stretch lengthwise when
in use.
For this purpose the bands or straps are composed of fillets or layers
of leather and fabric united either by means of a strong adhesive
substance, such as glue, or by sewing, or both, and consolidated if
required by band or mechanical pressure, so as to form bands or
straps.
In some cases the required thickness of the band or strap will be
produced by alternate fillets or layers of leather and fabric, and in

page_text: other cases by fillets or layers of fabric between two external fillets of
leather.
When the bands or straps are required to be of considerable width,
they will be made by uniting two or more fillets laterally; and when the
bands or straps are required to be narrow they can be cut from wider 5
bands or straps.
Bands and straps manufactured as above described are applicable for
use in machinery, and also for other uses in which it is desirable to
counteract the ordinary tendency of leather straps to elongate by
tension.
1
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I
claim as of my Invention is, the manufacture of bands and straps com-
posed of fillets or layers of leather and fabric united as required either
by means of an adhesive substance, or by sewing or otherwise, and 1
adapted by their diminished liability to stretch, for use in machinery,
and for other uses as described.
In witness whereof, I, the said Jean Baptiste Colnot, have hereunto
set my hand and seal, the Thirteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-two.
and for other uses as described.
In witness whereof, I, the said Jean Baptiste Colnot, have hereunto
set my hand and seal, the Thirteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-two.
