IMPROVED MACHINERY FOR BURRING OR CLEANING WOOL
Year: 1864

page_text: LETTERS PATENT to Edouard Frederic Pastor, junior, of Borcette, near
Aix-la-Chapelle, in the Kingdom of Prussia, Spinner, for the Invention
of "IMPROVED MACHINERY FOR BURRING OR CLEANING WOOL."
Sealed the 16th August 1864, and dated the 2nd March 1864.
PROVISIONAL SPECIFICATION left by the said Edouard Frederic Pastor
at the Office of the Commissioners of Patents, with his Petition, ou
the 2nd March 1864.
I, EDOUARD FREDERIC PASTOR, junior, of Borcette, near Aix-la-Chapelle, in
the Kingdom of Prussia, Spinner, do hereby declare the nature of the said
Invention for "IMPROVED MACHINERY FOR BURRING OR CLEANING WOOL," to be
as follows:-
My Invention of improved machinery for burring or cleaning wool
consists in the adaptation to a rough wool carding engine of an apparatus for
removing from Buenos Ayres and other rough uncleaned wools all thistles,
burrs, straws, bits of stick, and other extraneous matters which are usually
found in such wools.

page_text: Attempts have been heretofore made to effect this object by means of card
cylinders, but it has been found that such apparatus as heretofore constructed
was liable to carry away with it a portion of wool, which would thereby be
lost. Moreover the cleaning operation was not properly effected.
In the improved machinery which forms the subject of the present Invention,
the wool is fed in between two rollers, one of which is provided with card teeth
to hold the wool, while the other is simply covered with leather, or some other
suitable substance. From these rollers it passes between another pair of
rollers, whereby the solid lumps are removed. The wool is then drawn out or
stretched lengthwise, so that the thistles and extraneous matters may be raised
above it, and in this state it passes to another and larger roller furnished with
cards, which catch hold of the wool and draw it between the teeth of a comb
(whereby some of the extraneous matters are removed) and over a knife edge
to a second comb provided with finer teeth, which will take out all that
remains of extraneous matters. Behind this is a second knife edge, and below
is a wire sieve to catch any small portions of wool that may become accidentally
detached. The wool is then taken by the large cylinder of the carding engine,
and is conveyed by it to the workers. One of the working rollers is removed
from the card cylinder, and a brushing cylinder is put in its place, for the
purpose of sweeping off the dust and dirt. This cylinder revolves very
rapidly, and throws all the dirt into an iron trough placed behind it, and in
order to prevent this trough from getting heaped up and filled, and the dirt
and other extraneous matters from falling back into the machine, a rotating
shaft provided with two leather flappers is mounted thereon and made to
rotate slowly, so as to push the dirt forward. I sometimes find it convenient
to place a second brushing and dusting apparatus behind the one just described,
as when the machine is working fast some of the dirt will fly back into the
machine

Patent, bearing date the Second day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Edouard Frederic Pastor, Her special license that I, the
said Edouard Frederic Pastor, my executors, administrators, and assigns, or
such others as I, the said Edouard Frederic Pastor, my exccutors, adminis-
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 "IMPROVED MACHINERY FOR BURRING OR CLEANING WOOL,"
upon the condition (amongst others that I, the said Edouard Frederic Pastor,
by an instrument in writing under my hand and seal, 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 Edouard Frederic Pastor, 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, reference being had to the Drawing hereunto aunexed,
and to the letters and figures marked thereon (that is to say):-
My Invention of "Improved Machinery for Burring or Cleaning Wool"
consists in the adaptation to a rough wool carding engine of an apparatus for
removing from Buenos Ayres and other rough uncleaned wools, all thistles,
burrs, straws, bits of sticks, and other extraneous matters which aro usually
found in such wools.
Attempts have been beretofore made to effect this object by means of card
cylinders, but it has been found that such apparatus as heretofore constructed
was liable to carry away with it a portion of wool, which would theroby be
lost. Morcover the cleaning operation was not properly effected.
The improved machinery which forms the subject of the presunt Invention
is shewn in the accompanying Drawing, in which Fig. 1 is a diagram or
sectional elevation of so much of a wool carding engino as is necessary to
explain the Invention.
C represents the large cylinder of a wool carding engine. The wool is fed
into the machine between the two rollers L and M, one of which, L, is pro-

page_text: vided with card teeth to hold the wool, while the other, M, is simply covered
with leather, or some other suitable substance. By this arrangement the
thistles and hard substances are prevented from being imbedded in the wool.
From these rollers the wool passes between another pair of rollers I and K,
whereby the solid lumps or hard substances are removed. These rollers I
and K form a kind of rough picking apparatus somewhat similar in con-
struction to that usually employed for an analogous purpose in other cleaning
machinery. The wool in passing from this apparatus is drawn out or stretched
lengthwise, so that the extraneous matters may be raised above the sheet of
fibres, and in this state the wool passes to my picking apparatus, which is
shewn detached in elovation at Fig. 2, and consists of a large roller A furnished
with cards, which catch hold of the wool and draw it between the teeth of a
comb G (whereby some of the extraneous matters are removed) and over a
knife edge F to a second comb G', provided with finer teeth, which will take
out all that remains of extraneous matters. Behind this is a second knife
edge F¹, and below is a wire sieve H to catch any small portions of wool that
may become accidentally detached. The wool is then taken by the large
cylinder C of the carding engine, and is conveyed by it to the workers N, N, N.
Instead of the number of working rollers usually employed, one is removed
from the card cylinder, and a brushing cylinder B is put in its place for the
purpose of sweeping off the dust and dirt from the sheet of wool. This
cylinder revolves very rapidly, and throws all the dirt into an iron trough D
placed behind it, and in order to prevent the trough D from getting heaped up
and filled with the dirt and other extraneous matters brushed from the wool,
and also to prevent the dirt from falling back into the machine or on to the
wool, a rotating shaft provided with two leather flappers, as at D*, is mounted
thereon, and made to rotate slowly, so as to push the dirt forward and deliver
it into any suitable receptacle placed there for the purpose. This apparatus is
shown detached in elevation at Fig. 3. I sometimes find it convenient to place
a second brushing cylinder P and dusting apparatus and trough D' behind the
one just described, as when the machine is working fast some of the dirt will
fly back into the machine, and must therefore be removed before the sheet of
wool can be delivered in a clean state.
Having now described my Invention of improved machinery for burring
or cleaning wool, and having explained the manner of carrying the same into
effect, I claim as the Invention secured to me by Letters Patent, as aforesaid,
the adaptation to carding machines of the feeding rollers L and M, constructed
as herein described, in combination with the pickers 1 and K, and the card

page_text: roller A with the comb bars G and G', and the knife edges F and F', and
also the application of the brushing or cleaning rollers B and P with their
accessory parts.
In witness whereof, I, the said Edouard Frederic Pastor, junior, bavo
hereunto set my hand and scal, the Twenty-third day of August, in
the year of our Lord One thousand eight hundred and sixty-four.
