WOOL CARDING ENGINES (A communication to me from
abroad by Clemens Rüdiger of Forst, Lusatia, Germany)
Wool carding engines constructed according to this invention differ from the
usual machines for such purpose mainly in that each of the main carding cylinders
(tambours) which are provided with workers or working rollers, works by itself and
conveys the material on further so that no part of same comes back. This returning
of the material is a fault in other carding engines such for instance in which the
workers are placed both above and below in the spaces between the main cylinders.
The consequence of such an arrangement is that every other worker conveys the
caught material back to the preceding main carding cylinder (tambour). Such a
continuous return of the work is unprofitable for another reason because the cards.
on the first main carding cylinder are coarser than the cards on the following main
carding cylinders which have finer and finer cards, and the material will thus be
carried back to the coarser cards after it has passed on to the finer cards
The machine constructed according to this invention avoids this evil by reason
of its peculiar arrangement or construction.
Two or more main carding cylinders say for instance three such are arranged
close to each other and are provided each with two or more workers or working
rollers. The two first main carding cylinders are made so light and small that they
may easily be removed for the purpose of cleaning. The material coming from the
feed apron passes between feed-rollers on to the preparatory or taking in rollers
which convey it on to the first main carding cylinder; this latter is provided above
with, say three working rollers and two intermediate stripping rollers. The working
[Price 6d1

page_text: rollers are driven by chains and the stripping rollers or strippers by straps, as is
generally the case.
The speed of the revolving parts is such, that the first working roller on each
carding cylinder revolves quicker than each following one.
The first working rollers take hold of the wool, which has been conveyed thereto
by the main carding cylinder, but immediately give it off again because of their
quick revolving speed and cause it to undergo an increasingly stronger combing
process in passing to the following and slower and slower revolving working
rollers whereby the material thus passing through is treated as gently as possible
The next and contiguous main carding cylinder then catches hold of the wool
thus far prepared and conveys it to, say, two lower working rollers with an inter-
mediate stripper and thence the wool passes on to the third or large carding
cylinder. The wool can thus not be carried back as the second carding cylinder
with its working and other rollers also works separately.
The large carding drum is provided with a series of working rollers, say three in
number and corresponding stripping rollers; the material having passed through
this part of the machine in a similar manner as with the two other carding
cylinders, is conveyed on to a very quickly revolving fancy roller or flyer (volant)
which is fitted with long tooth cards which roller takes the prepared wool out of
the teeth of the large carding cylinder and throws it on to the dofling or taking off
roller (peigneur). The fleece is then removed from the latter by means of a
quickly oscillating comb in the usual manner and conveyed away for further
treatment.
The essential feature of this invention is then that each carding cylinder, solely
by the increased speed of its working surface and without the intervention.of other
rollers such as flyers or doffers, takes the material directly from the preceding one
for the purpose of further treatment, whereby the material is gradually worked
without the possibility of a return of the material to a carding cylinder which it
has already passed.

EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex
"IMPROVEMENTS IN WOOL CARDING ENGINES A communication to me from
abroad by Clemens Rüdiger of Forst, Lusatia, Germany
Wool carding engines constructed according to this invention differ from the usual
machines for such purpose mainly in that each of the main carding cylinders
(tambours) which are provided with workers or working rollers, works by itself and
conveys the material on further so that no part of same comes back. This returning
of the material is a fault in other carding engines such for instance in which the
workers are placed both above and below in the spaces between the main cylinders.
The consequence of such an arrangement is that every other worker conveys the
caught material back to the preceding main carding cylinder (tambour). Such a
continuous return of the work is unprofitable for another reason because the cards
on the first main carding cylinder are coarser than the cards on the following main
carding cylinders which have finer and finer cards, and the material will thus be
carried back to the coarser cards after it has passed on to the finer cards.
The machine constructed according to this invention avoids this evil by reason of
its peculiar arrangement or construction.
And in order that this invention may be more fully understood I will proceed to
describe it with reference to the accompanying drawing.
Two or more main carding cylinders say for instance three such B C and D as
here shown are arranged close to each other and are provided each with two or
more workers or working rollers b, c, d, e, f, g, h, and i. The two first main carding
cylinders B and C are made so light and small that they may easily be removed
for the purpose of cleaning. The material coming from the feed apron G passes
between feed rollers 7, 8 and 9 onto the preparatory or taking in rollers A and a
which convey it onto the first main carding cylinder B; this latter is provided
above with say three working rollers b c and d and two intermediate stripping
rollers 1 and 2. The working rollers are driven by chains and the stripping rollers
or strippers by straps as is generally the case.
The speed of the revolving parts is such that the first working roller on cach
carding cylinder revolves quicker than each following one. In this therefore b
would run quicker than c, and c quicker than d.
The first working rollers take hold of the wool which has been conveyed thereto
by the main carding cylinder B but immediately give it off again because of their
quickly revolving speed and cause it to undergo an increasingly stronger combing
process in passing to the following slower and slower revolving working rollers
whereby the material thus passing through is treated as gently as possible.
The next and continguous main carding cylinder C then catches hold of the wool
thus far prepared and conveys it to, say, two lower working rollers e and f with an
intermediate stripper 3 and thence the wool passes on to the third or large carding
cylinder D. The wool can thus not be carried back as the second carding
cylinder C with its working and other rollers, also works separately.
The large carding drum D is provided with a series of working rollers, say three
in number ghi and corresponding stripping rollers 4, 5 and 6; the material
baving passed through this part of the machine in a similar manner as with the
two other carding cylinders is conveyed onto a very quickly revolving fancy roller
or flyer (volant) E which is fitted with long tooth cards which roller takes the
prepared wool out of the teeth of the large carding cylinder D and throws it onto

page_text: the doffing or taking off roller (peigneur) F. The fleece is then removed from the
latter by means of a quickly oscillating comb I in the usual manner and conveyed
away for further treatment.
The essential feature of this invention is then that each carding cylinder, solely
by the increased speed of its working surface and without the intervention of other
rollers such as flyers or doffers, takes the material directly from the preceding one
for the purpose of further treatment, whereby the material is gradually worked
without the possibility of a return of the material to a carding cylinder which it
has already passed.
I claim as the invention communicated to me:
A carding engine having two or more immediately contiguous carding cylinders
such for instance as B C and D each of which is separately provided with two or
more workers such for instance as b, c, d, e, f, g, h and i, and with the corresponding
strippers such for instance as 1, 2, 3, 4, 5 and 6, all arranged in such a manner that
by the different surface speeds the first carding cylinder gives off the material
directly to the next carding cylinder or cylinders, that the material by the different
speeds of the workers is gradually being treated, and that a partial return of the
material to a carding cylinder which it has already passed becomes impossible all
substantially as described, and as illustrated in the accompanying drawing.
In witness whereof I the said Edward Griffith Brewer have hereunto set
my hand and seal this Twentieth day of January in the year of our Lord
One thousand eight hundred and eighty three:
E & BREWER.
