Year: 1875

page_text: LETTERS PATENT to Paul Boucley, of the Firm P. Boucley, and Co.,
of Nonancourt (Eure), France, Manufacturers, for the Invention of
"IMPROVEMENTS IN MANUFACTURING STRAPS, BANDS, HARNESS, ROPES, PIPES,
OR OTHER ARTICLES.'
"
Sealed the 13th July 1875, and dated the 6th February 1875.
PROVISIONAL SPECIFICATION left by the said Paul Boucley at the
Office of the Commissioners of Patents, with his Petition, on the
6th February 1875. .
.
I, PAUL BOUCLEY, of the Firm of P. Boucley and Co., of Nonancourt
(Eure), France, Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MANUFACTURING STRAPS, BANDS, HARNESS,
ROPES, PIPES, OR OTHER ARTICLES," to be as follows:-
:-
This Invention relates to the manufacture of straps, bands, harness,
ropes, pipes, and other articles of like kind usually made of leather,
caoutchouc, gutta percha, or of tissue combined with agglutinating or
waterproofing material. As tissues are ordinarily employed in the manu-
"

page_text: facture of such articles the warp or only one set of the threads of the
tissue has to sustain all the strain, the weft or other set of threads
serving only to bind the former together. Moreover the threads which
are subjected to the strain being intertwined with the others are not
capable of giving the resistance which they could offer if strained in the
direction of their length, and in tending to straighten themselves they
disintegrate the fabric.
According to my Invention I employ only one set of threads, laid side
by side and agglutinated, so that when the article is strained the threads
are in the best condition for resisting the tension and have no tendency
to change their relative positions. For this purpose I draw off from a
number of bobbins or from a warp beam the number of threads required
to constitute the breadth of the article and pass them through a reed.
They then pass under a spout from which flows the agglutinating or
waterproofing solution in the condition of syrup laid evenly over them;
and finally the warp thus served is wound on a reel or beam, transverse
bars being inserted at intervals to prevent the one turn from adhering
to that below it. The material is afterwards unwound and served on
the other side. The agglutinating fluid employed in any known solution
of caoutchouc, or gutta percha, or boiled oils, which may be charged
with sulphur, sulphides, or other vulcanising agents, and with colouring
matter when desired.
Instead of applying the agglutinating matter as above described the
warp after passing through the reed may be carried between the rollers
of a calendar such as is usually employed for caoutchoucising fabric and
treated as fabrics are ordinarily treated for that purpose.
In making straps I place together a number of warps, prepared as
above described one over the other, putting in the middle a piece with
its fibres crosswise for the purpose of resisting the strain of rivets, tangs
of buckles, and the like, which are passed through holes in the strap,
and I cover the whole with a layer of caoutchouc or other like material,
and then vulcanise it in the usual way; or caoutchouc fabric instead of
caoutchouc itself may be employed as a cover.
In making pipes I wind warp prepared as above described on a
mandril in helical form, taking care that the edges of the successive
turns come close together. I cover this layer with another wound to

page_text: the opposite hand, and so on successively till the desired thickness of
substance is attained, and I cover the whole with a coat of caoutchouc
and vulcanise it. And generally for other articles I proceed as is usually
done with tissues, employing instead of the ordinary tissues warps pre-
pared as I have described. In order to withstand the heat of vulcanising
vegetable fibres should be employed in forming these warns.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Boucley in the Great Seal Patent Offico
on the 16th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
BOUCLEY, of the Firm of P. Boucley and Co., of Nonancourt (Eure),
France, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent, bearing date the Sixth day of February, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Paul Boucley, Her
special license, that I, the said Paul Boucley, my executors, admi-
nistrators, and assigns, or such others as I, the said Paul Boucley,
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
"IMPROVEMENTS IN MANUFACTURING STRAPS, BANDS, HARNESS, ROPES, PIPES,
OR OTHER ARTICLES," upon the condition (amongst others) that I, the
said Paul Boucley, 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

page_text: 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 Paul Boucley, do hereby declaro
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 thereof, that is to say:
This Invention relates to the manufacture of straps, bands, harness,
ropes, pipes, and other articles of like kind, usually made of leather,
caoutchouc, gutta percha, or of tissue combined with agglutinating or
waterproofing material. As tissues are ordinarily employed in the
manufacture of such articles the warp or only one set of the threads of
the tissue has to sustain all the strain, the weft or other set of threads
serving only to bind the former together. Moreover the threads which
are subjected to the strain being intertwined with the others are not
capable of giving the resistance which they could offer if strained in the
direction of their length, and in tending to straighten themselves they
disintegrate the fabric.
According to my Invention I employ only one set of threads, laid side
by side and agglutinated, so that when the article is strained the threads
are in the best condition for resisting the tension and have no tendency
to change their relative positions. For this purpose I draw off from a
number of bobbins or from a warp beam the number of threads required
to constitute the breadth of the article and pass them through a reed.
they then pass under a spout from which flows the agglutinating or
waterproofing solution in the condition of syrup, which is laid evenly
over them by means of a knife or doctor; and finally the warp thus
served is wound on a reel or beam, transverse bars being inserted at
intervals to prevent the one turn from adhering to that below it, and to
give spaces between the convolutions for access of air to dry. The material
thus formed of a number of warp threads agglutinated together is after-
wards unwound and served on the other side. The agglutinating fluid
employed is any known solution of caoutchouc, or gutta percha, or
boiled oils, which may be charged with sulphur, sulphides, or other
vulcanising agents, and with colouring matter when desired.
:
Instead of applying the agglutinating material as above described the
warp after passing through the reed may be carried between the rollers

page_text: of a calender such as is usually employed for caoutchoucising fabric,
and treated as fabrics are ordinarily treated for that purpose.
In making straps I place together a number of warps, prepared as
above described, one over the other, putting in the middle a piece with
its fibres crosswise for the purpose of resisting the strain of rivets, tangs
of buckles, and the like, which are passed through holes in the strap,
and I cover the whole with a layer of caoutchouc or other like material,
and then vulcanise it in the usual way; or caoutchouc fabric instead of
caoutchouc itself may be employed as a cover.
In making pipes I wind warp prepared as above described on a
mandril in helical form taking care that the edges of the successive
turns come close together, I cover this layer with another wound to the
opposite hand, and so on successively till the desired thickness of
substance is attained, and I cover the whole with a coat of caoutchouc
and vulcanise it. And generally for other articles I proceed as is
usually done with tissues, employing instead of the ordinary tissues
warps prepared as I have described. In order to withstand the heat of
vulcanising vegetable fibres should be employed in forming these warps.
In some cases to prevent displacement of the warp threads I apply
cross threads at considerable intervals apart.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I claim,—
First. The method, substantially as herein described, of manufacturing
warp fabric, consisting of fibres agglutinated by caoutchouc and such
like substances, these fibres not being woven but laid side by side as
warp, or with their lengths laid in the direction of the strain to which
they are to be subjected.
Second. The method, substantially as herein described, of manu-
facturing bands or straps by the superposition and agglutination of
pieces of warp fabrics such as are above referred to with an intermediate
piece of fabric having its fibres transverse.
Third. The method, substantially as herein described, of manufacturing
flexible pipes by agglutinating and coating pieces of warp fabrics such
as are above referred to helically wound on a mandril in two or more
layers crossing each other.

page_text: Fourth. The use of straps, bands, harness, ropes, pipes, or other
articles of like kind, manufactured substantially according to the
methods herein described.
In witness whereof, I, the said Paul Boucley, have hereunto set my
hand and seal, this Thirteenth day of July, in the year of our
Lord One thousand eight hundred and seventy-five.
