Year: 1859

page_text: LETTERS PATENT to Louis Henri Ignace Lemaire, of Stamford Street,
bi
Blackfriars, in the County of Surrey, Commercial Traveller, for the
Invention of IMPROVEMENTS IN THE MANUFACTURE OF CHENILLE.",
Sealed the 30th March 1860, and dated the 3rd October. 1859.
PROVISIONAL SPECIFICATION left by the said Louis Henri Ignace
Lemaire at the Office of the Commissioners of Patents, with his Petition,
on the 3rd October 1859.
I, LOUIS HENRI IGNACE LEMAIRE, of Stamford Street, Blackfriars, in the
County of Surrey, Commercial Traveller, do hereby declare the nature of
:the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CHENILLE,
be as follows:-
Chenille is now ordinarily made from silk threads woven with cotton threads
between every set of silk threads, and each row of silk threads is subsequently
cut by scissors, the cotton threads serving as a guide to enable the operator to
cut without injury to the silk threads. After being separated the silk threads
are twisted and form chenille.
Now my Invention consists in weaving two wires between every row of silk
threads, and in constructing a cutting apparatus formed of a holder in which
as many blades are mounted as there are rows to be cut. The distance
between the blades is adjustable to adapt the blades to different widths of silk.
As soon as the fabric is finished, it is subjected to the cutting apparatus; the

page_text: blades in which are set to cut between each pair of wires. The fabric is either
drawn past the cutting apparatus, or the cutting apparatus is drawn along the
fabric; after the cutting has been effected the wires are removed and the
chenille is finished in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the, Letters Patent, filed
by the said Louis Henri Ignace Lemaire in the Great Seal Patent Office
on the 3rd April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
HENRI IGNACE LEMAIRE, of Stamford Street, Blackfriars, in the County of
Surrey, Commercial Traveller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord Onc
thousand eight hundred and fifty-nine, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Louis Henri Ignace Lemaire, Her special licence that I, the said Louis
Henri Ignace Leinaire, my executors, administrators, and assigns, or such
others as I, the said Louis Henri Ignace Lemaire, my executors, admi-
nistratore, 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 MANUFACTURE OF CHENILLE,"
upon the condition (amongst others) that I, the said Louis Henri Ignace
Lemaire, 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 Louis Henri Ignace Lemaire, 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 thereof, reference being had to the Drawings.hereunto
annexed, that is to say :-
Chenille is now ordinarily made from silk threads woven with cotton threads.
between every set of silk threads, and each row of silk threads is subsequently.

page_text: cut.by scissors, the cotton threads serving as a guide to enable the operator to
cut without injury to the silk threads. After being separated the silk threads.
are twisted and form chenille.
Now
my Invention consists in weaving two or more wires between every
row of silk or other threads composing the chenille, and in constructing a
cutting apparatus formed of a holder in which as many blades are mounted as
there are rows to be cut. The distance between the blades is adjustable to
adapt the blades to different widths of silk. As soon as the fabric is finished,
it is subjected to the cutting apparatus, the blades in which are set to cut
between each pair of wires. The fabric is either drawn past the cutting
apparatus, or the cutting apparatus is drawn along the fabric. After the
cutting has been effected, the wires are removed and the chenille is finished in*
the ordinary manner.
'
Figure 1 of the accompanying Drawings shows in side elevation, partly in.
section, and Figure 2 in plan, so much of an apparatus for cutting.chenille as.
will be necessary to illustrate the manner in which I carry my Invention into
effect. A, A, are drums or rollers round which the chenille, which is woven
as before described, is wound; B, B, are circular knives or cutting surfaces
mounted upon a shaft.C; D, D, are guards between which and the knives the
cheuille passes, the wires in the fabric.coming one or more on each side.of
every separate knife. Rotary motion is communicated to the shaft.C, and
thence to the knives B, B, through.a pinion a, gearing into the bevil wheel b
mounted on a shaft c, which carries a pulley a, round which a strap passes to
a second.pulley e, which itself receives motion from a winch handle or treadle:
not shown in the Drawing. The drum A is mounted ou the same shaft a's: the
pulley e, by which arrangement.the same power which communicates rotary.
motion to the knives B, B, also imparts motion to the drum A, and.as.the
latter drum revolves, the chenille which surrounds it, and the drum A' is
caused to advance against the knives, which cut the fabric between the wires,
and divide it into strips of chenille. The knives are fi
fitted in such manner to
the shaft C that their position. can be altered at will, and any number of knives
can be employed, according to the number of wires woven into the fabric.
Figure.3.is an end elevation.; Figure 4, a side elevation partly in section;
and Figure 5, a plan of a different machine for cutting between the wires
woven in the chenille fabric in which the knives or cutting surfaces are
arranged to work in an up and down direction, and to make a drawing cut.
A, A', are the two drums round which the chenille is stretched. The shaft on
which the drum A is mounted carries a pulley a, round-which a strap passes
to a second pulley 6 on a shaft c, to which rotary motion is communicated by

page_text: a treddle d; e is a rod linked to the treddled, and to a frame f, which carries
a number of knives or cutting surfaces g, g. This frame f works in grooves
formed in the side supports h, h, and is guided in its motion by a rod i con-
nected to its upper part, and passing through the top part of the frame, as
shown; k is a grooved support for the fabric between which the knives pass
in
their to-and-fro motion. On motion being communicated to the treddle d,
the drum A, and with it the drum A¹ revolve, thereby drawing the chenille
along while the to-and-fro motion of the frame f, which motion is produced by
the same treddle d that communicates motion to the drums, causes the knives
to pass through the fabric between the wires, and divide the chenille into
strips. The chenille fabric in this machine is shown the whole width of the
drums, but chenille fabrics of any other width can be cut.
According to another arrangement I fix the knives to a cam to which a
rotary motion is imparted by a treddle crank and connecting rods as before,
and the chenille is stretched round drums, and cut in a similar manner to that
before described.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the manufacture of chenille by weaving two or more wires between
every row of threads of which the chenille is composed, as herein-before
described.
Second, the employment in apparatuses for cutting chenille of knives or
surfaces having a rotary to and fro or other motion imparted to them, as
herein-before described and illustrated in the accompanying Drawings.
Third, the arrangements of apparatuses for imparting motion to the knives
or surfaces in chenille cutting machines or apparatuses herein-before described
and illustrated in the accompanying Drawings.
In witness whereof, I, the said Louis Henri Ignace Lemaire, have here.
unto set my hand and seal, this Thirty-first day of April, One thousand
eight hundred and sixty.
