Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE MANIQUET, of Paris, but now of the Saboniere Hotel, Leicester
Square, in the County of Middlesex, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Second day of November, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Jean Baptiste Maniquet, Her especial licence, full power, sole privilege and
authority, that I, the said Jean Baptiste Maniquet, my exors, adñiors, and
assigns, or such others as I, the said Jean Baptiste Maniquet, my exors,
adiiors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the terms of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
DOUBLING, TWISTING, AND REELING SILK, COTTON, AND OTHER SUBSTANCES;" in
which said Letters Patent is contained a proviso that I, the said Jean
Baptiste Maniquet, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be inrolled
in Her said Majesty's High Court of Chancery, within six calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
arge appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Jean Baptiste Maniquet, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and to the figures and letters
marked thereon (that is to say):
The Invention consists of,-
:-
First, an apparatus to be applied to machines for doubling, twisting, and
reeling silk, cotton, or other fibrous substances, whereby the inequality of the
surfaces of the material being twisted is avoided, which inequality arises from
the difference of the thickness of the strands of which the material is composed.
The principle of this first apparatus rest upon the capability of regulating the
tension and the length of the strands separately, according to their thicknesses,
which has not been done heretofore; and,
Secondly, an apparatus with appealing rollers, which always draw the same
length of the strands, whatever be the difference of the thickness of the
strands. The constant unfolding of the strands is obtained by the appealing
rollers, which establisch a stationary point, and by these means the ravelling is
avoided, and a perfectly regular cord is obtained.
DESCRIPTION OF THE DRAWING.
Fig. 1 is a front view of the apparatus, on the first principle. Fig. 2 is a
side view. a is on bobbins of several belonging to a machine for spinning.
bare three strands coming from the bobbins a, a, which may be arranged in
any suitable manner. These strands, in passing through the apparatus, have
given to them a tension and length in proportion to their thickness, before they
are spun into the cord. c is a framing to support some of the parts of the
apparatus. d, d¹, are holders. There are two corresponding ones for each
thread or strand. These holders d, d', are shown separately in Figures 3 and
4. Fig. 3 is a side view, and Fig. 4 is a front view, and the are formed of
two spring blades joined at the lower part, with elasticity from the lower to
the upper part. The thread passes across the holder d, through a space e,
formed by the two blades of the holder; this space may be closed more or less
as required by the screw f. g is a bar projecting from and affixed to the
framing c, and carrying the three rings h through which the thread 6 pass.
i, i, i, are three levers moving on an axis at i¹. At the lower part of these
levers are hooks j; also a projecting piece, having a hole therein, through which
a cord passes. m, m, m, are pulleys turning in bearings at n; each strand
passes over the corresponding pulley. At the ends of these cords are attached

having several grooves formed thereon. r is the flyer, through holes in which
the strands pass to the bobbin, around which it is wound, as shown at Figure 1.
s is the winder, or it may be a bobbin t, as shown at Figure 2; either may be
used; but all that will be necessary will be to change the position of the holes
through which the threads pass; no other change is necessary. Each thread,
as it comes from the bobbin a, passes through the space e of the holder d, in
the same line, then through the rings h and j. It then passes over the lower
roller and round the upper roller p', and passes into one of the grooves of the
roller q, and passes down over this roller, to be. joined with the other threads
that have passed through the same course, to be formed into a cord by the
rotation of the spindle and flyer r. And when wound on the winder s or bobbin t,
it will be seen, from the arrangement of this apparatus, that the thread which
comes from the bobbin a passes (either directly or through a similar guide to
the rings h and j) into the space of the first holder d, where it undergoes a
a slight pressure, from thence into the opening of the lower holder d, where it
receives a still greater pressure, and then passes into the hook hand into
hooks of one of the levers i; but when the equilibrium no longer exists
between the pressure or friction that the thread is subjected to between the
holders and the counter weight o, then the lever i receives a to and fro move-
ment from the left or from the right, according as the pressure of the thread
between the holder is stronger or weaker than the action of the weight; that is
to say,
that the thread comes thicker as it undergoes greater pressure in the
holder, and vice versa.. In the first case the lever i is drawn from the side of
the holder; in the second case the lever is drawn by the weight; from which
will follow, that the thread will be found, as the lever is drawn either from the
left or from the right, to take into the larger or smaller of the grooves upon
the conical roller 4. which increases or diminishes the tension and the length
of the thread. This apparatus may be varied, in the form and number of the
holders and levers and threads. Figure 5 shews a spring which may be
employed in place of the weight o. Figure 6 shows a forked piece V, with a
lever joined to it. The inequality of the thread will be communicated from
the end of the lever 2, to the forked piece V, in order that may press more or
less upon the bobbin a. Fig. 7 is the second apparatus, which is drawing a
constant length of strands, whatever be their unequal thickness. The axle a
of the bobbin 6 is fixed upon the disk c, which is hollow. Upon the bearing d
is placed around the axle a, a stationary wheel e, in contact with a similar
wheelf, the pin g of which is beared by the disk c, and surrounded with a
roller h. The disk c holds a roller i into contact with the roller h; when the

page_text: axle a is revolving by the pulley j, the disk c revolves also, and with it the
wheel f, movable around the stationary wheel c. Then the thread coming
from the bobbing b, pass through the hooks l, m, and around the rollers h, i,
and after through the hooks o, p, around the winder or bobbin, as shown at
Figures 1 et 2; by these means the rollers h, i, draw always the same length of
strands. There are three similar apparatus, more or less, according to number
of strands of which the cord is to be made.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood, that do not confine myself to
the form and size of apparatus, nor to the materials of which they are made,
nor to the number of strands. But what I claim is, the mode or principle of
arranging apparatus for doubling, twisting, and reeling silk, cotton, and other
fibrous substances.
In witness whereof, I, the said Jean Baptiste Maniquet, have hereunto
set my hand and seal, the Twenty-eighth day of April, in the year of
our Lord One thousand eight hundred and forty-five.
