Year: 1852

page_text: LETTERS PATENT to Jean Joseph Jules Pierrard, Manufacturer, of
Paris, in the French Republic, for the Invention of "IMPROVE-
MENTS IN PREPARING WOOL AND OTHER FIBROUS SUBSTANCES FOR
COMBING."
Sealed the 9th February 1853, and dated the 19th November 1852.
PROVISIONAL SPECIFICATION left by the said Jean Joseph Jules
Pierrard at the Office of the Commissioners of Patents, with
his Petition, on the 19th November 1852.
I, JEAN JOSEPH JULES PIERRARD, Manufacturer, of Paris, in the
French Republic, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PREPARING WOOL AND OTHER FIBROUS SUBSTANCES
FOR COMBING" to be as follows:-
My Invention consists of feeding wool or other fibre by means of
an endless apron and rollers on to a series of combs or rows of points,
the heads of which are caused to slide in a grooved course by means
of two revolving slotted guide plates, the slots being so formed as to
cause each set of points to progress faster than the one immediately

page_text: behind it. From these combs so noved the wool or other fibre is
drawn by means of rollers, after which it is wound on a drum, or
received in any other convenient manner.
The combs and feeding rollers may be heated or not as is best for
the fibre to be operated upon.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by. the said Jean Joseph Jules Pierrard in the Great
Seal Patent Office on the 5th May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JEAN JOSEPH JULES PIERRARD, Manufacturer, of Paris, in the French
Republic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of November, in the
year of our Lord One thousand eight hundred and fifty-two, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jean Joseph Jules Pierrard, Her
special licence that I, the said Jean Joseph Jules Pierrard, my exc-
cutors, administrators, and assigns, or such others as. I, the said Jean
Joseph Jules Pierrard, 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 PREPARING WOOL AND
OTHER FIBROUS SUBSTANCES FOR COMBING," upon the condition (amongst
others) that I, the said Jean Joseph Jules Pierrard, by an instru-
ment in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention and in what
inanner 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 Joseph Jules Pierrard, do
liereby declare the nature of the said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
My Invention consists of feeding wool or other fibre by means of
an endless apron and rollers on to a series of combs or rows of points
the heads of which are caused to slide in a grooved course by means
of two revolving slotted guide plates; the slots being so formed as
to cause each set of points to progress faster than the one immediately
behind it. From these combs so moved the wool or other fibre is
drawn by means of rollers, after which it is wound on a drum or
received in any other convenient manner. The combs and feeding
rollers may be heated or not as is best for the fibre to be operated
upon.
And in order that my said Invention, and the manner of perform-
ing the same, may be most fully understood, and readily carried
into effect, I will proceed to describe the means employed by me.
DESCRIPTION OF THE DRAWINGS.
Figure 1, is a vertical and longitudinal section of the machine
arranged according to my Invention, and Figure 2, is a plan. A, is
the main shaft, on which is placed the driving pullies a, a¹, the
driving band being made to slide from one to the other by means
of the fork b, in the usual manner; C, C, is the principle framing of
the machine. Two similar pinions c, c, are fixed on the shaft A,
which work into two wheels d, d, on an axis f, which carries two
pinions of the same diameter g, g, which work into the large wheels
h, h, of the two grooved plates B, B.
These grooved plates are mounted on an axis i, and the grooves
or slots are shewn at e, e. On the framing C, C, are fixed two other
frames D, D, in which are formed the grooved courses j, to receive
the ends of the combs 1, 1, which ends also pass into the slots e, c, of
the plates B, B.
The wool or other fibre is placed (as is shewn at E) on an
endless apron m, this apron having fixed to it cross pieces of wood
or metal, as is partly shewn in the Drawings. The apron passes
round the rollers n, o, and is caused to move progressively forward

page_text: by the motion of the roller o, which turned by the train of wheels p,
p, p, the intermediate wheel p³, and 24, on the axis p, which axis
also carries the bevelled wheel p5, which works into p7 on the main
shaft, and thereby the train of wheels receives motion. The fibre
E, guided by the roller q, is taken by the rollers 7, 4. The interior
space G, inside the endless apron m, may contain a steam vessel to
heat the fibre before being subjected to the operation when de-
sirable.
On leaving the rollers r, ¹, the wool is placed on the points 7, and
the entering of the points may be aided by means of a brush s, or
other instrument acted on by the spring t, and caused to move
backwards and forwards by means of the lever H, on the axis I with
the counterpoise J, and another lever on the same axis I, which is
struck by projections u, u, on Plate B. Thus the combs l, are held-
at the extremities both by the grooves j, of the framing D,
D, and in the slots e, of the plates B, B. These plates B, in turning
move the combs 1, along the groove at a speed determined by the
curve of the slot e, and thus act on the fibre in the manner desired.
The space G2, in the interior of the frame D, may also contain a
steam box to heat the combs. The combs l, l, are kept clean by
means of a rotatory brush v, driven by the pullies x, x', x2, and the
cords y¹, y. The fibre after it has been worked by the points is
taken by the drawing roller K, driven by the wheels Y, and Z, and.
is carried by the endless apron L, either to be wound on to the
drum M, which is shewn in red lines, or to be passed through the
bell mouthed tube N, which may either be fixed or caused to
revolve by the pinion P, and the wheels Q, Q', R, R¹. After
leaving this tube the fibre passes between the rollers S S¹, to be
wound upon the roller T, which is driven by the wheels U, V, X,
and has an alternating rectilinear motion to distribute the fibre on the
roller in the ordinary manner. In the use of this machine it will
frequently be found, when more perfect work is required, to pass the
fibre through the machine several times.
: Having thus described the nature of my Invention, and the
manner of performing the same, I would have it understood that I.

page_text: do not confine myself to the precise details herein shewn and
described so long as the peculiar character of my Invention be
retained. But what I claim is the combination and arrangement
of machinery for straightening wool and other fibres and preparing
them for combing herein described.
In witness whereof, I, the Jean Joseph Jules Pierrard, have
hereunto set my hand and seal, this Nineteenth day of April,
in the year of our Lord One thousand eight hundred and
fifty-three.
