AN APPARATUS APPLICABLE TO CARDING ENGINES FOR DIVIDING THE FLEECE OF WOOL OR OTHER FIBROUS MATERIAL INTO ANY NUMBER OF SLIVERS OR THREADS
Year: 1885

page_text: PROVISIONAL SPECIFICATION.
We THOMAS CHADWICK Number 254 Bury Road machinist and HARRY
THORNTON of Number 34 Bridgefield Street mechanic both situate at Oakenrod
in the Borough of Rochdale and County of Lancaster do hereby declare the
nature of our said invention for AN APPARATUS APPLICABLE TO CARDING ENGINES
FOR DIVIDING THE FLEECE OF WOOL OR OTHER FIBROUS MATERIAL INTO ANY
NUMBER OF SLIVERS OR THREADS to be as follows:-
Our invention has for its object the dividing of the fleece of wool into separate
slivers or threads as the material is delivered from the doffer of a carding engine
during the process of carding which results in utilizing the whole of the surface of
the doffer obviating the employment of rings thereon which seperate the fillets of
" cards" as heretofore consequently resulting in the production of a greater number
of threads than heretofore. For this purpose we employ a suitable metal bar fixed
longitudinally in front of the doffer and at or near the underside of the stripping
roller. On the said bar we provide any convenient number of metal strips or plates
which for convenience of description we will term "dividing plates" in connection
with such plates is a roller covered with leather or other suitable material termed
the "dividing roller the plates being preferably of curved or circular form and
are so fixed as to be in contact with the under or lower part of the circumference
of the "dividing roller" to which a suitable rotary motion is imparted.
As the fleece is delivered from the stripping roller as is well understood it is
deposited on the plates at the parts not in contact with the " dividing roller"
which plates are fixed by preference in close proximity to each other on the bar
before named thus the plates at that part form a receiving surface throughout the
length of the bar for the reception of the wool or other material which is then
under the influence of the "dividing roller" by the action of the said roller the
wool or other material is drawn between the roller and the " dividing plates" which
plates are provided conveniently on the curved or circular part thereof with a
suitable hooked shaped eye or eyes into which the material enters at these parts of
the plates a portion of the fleece is thus arrested its passage between the plates
and the roller the remaining portion is thus elongated or drawn out in the form of
a sliver or thread and delivered between the "dividing roller" and a roller in
contact there with and to which it is geared from thence it is passed between the
"rubber leathers" of the condensor as heretofore.

We THOMAS CHADWICK of number 254 Bury Road Machinist and HARRY
THORNTON of number 34,- Bridgefield Street mechanic both situate at Oakenrod
in the Borough of Rochdale and County of Lancaster, do hereby declare the
nature of our said invention for AN APPARATUS APPLICABLE TO CARDING ENGINES
FOR DIVIDING THE FLEECE OF WOOL OR OTHER FIBROUS MATERIALS INTO ANY
NUMBER OF SLIVERS OR THREADS and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
Our invention consists of a separate or independent arrangement of mechanism
to be applied to such machines known as "single rubber condenser carding engines"
and has for its object the dividing of the fleece or sheet of wool or other fibrous
materials into any convenient number of separate threads as the same is delivered
from the doffer of an ordinary single rubber condenser carding engine during the
process of carding by the application of our apparatus we are ennabled to utilize
the whole surface of the doffer which may be covered with "cards" and which is
a peculiarity in machines of this kind and as before named the whole surface of
the doffer is thus employed in the delivery of wool or other materials obviating
the employment of rings thereon consequently blank spaces or unproductive
surfaces as hitherto obviously a greater number of threads can be produced from
machines of equal dimensions with our apparatus attached than without, also
obviates the waste of material under the process of carding.
In order that our invention may be better understood we refer to the accom-
panying sheets of drawings Figure 1 is an end elevation of such portion of a carding
engine as is necessary to illustrate our invention shewing our apparatus applied
thereto.
Figure 2 is a front elevation at A B of Fig 1.
Figure is an end elevation of our apparatus drawn to a larger scale.
Figure 4 is a back elevation at C D of Fig 3.
Figure 5 is a view of what we term for convenience of description “dividing
plate."
"
We employ a suitable metal bar or carrier E fixed longitudinally in front of the
stripper K of the carding engine or at any convenient part thereof on the said
bar or carrier E we provide any convenient number of metal dividing plates G
being of form suitably so as to be adjusted to the under side or lower part of the
circumference of a metal fluted roller H termed the " dividing roller or if desirable
we may cover the said roller with leather or other suitable material fluted or
otherwise as may be required accordingly as various classes of materials are operated
upon or dealt with and as the case may be the said roller is suitably supported at
each extremity by brackets II fixed conveniently to the carrier E being supported
conveniently by adjustable- brackets J J which brackets are conveniently fixed to

page_text: the ordinary condenser slides thus the dividing roller with the plates are capable of
being adjusted to or from the rubber leathers of the condenser or to or from the
stripping roller or may be raised or lowered as the same are caused to wear by use
and as the case may be.
The operation of our invention is as follows: as the material is cleared from the
doffer F by the agency of the stripper K as is well known the material is carried
thereby and caused to enter between the dividing roller H and the dividing plates G
the said roller and plates being suitably adjusted to the stripper K and is thence
carried forward between the roller and the plates by the agency of the said roller
which has a rotary motion imparted thereto by the engagement of the wheel L on
one extremity of the said roller shaft with a corresponding wheel M on one extremity
of one of the rollers of the condenser shaft N which has a rotary and reciprocating
motion for the purpose of condensing and carrying forward the threads as is well
known in ordinary carding machinery. The material being drawn on to the
surfaces of the plates which are fixed on the carrier E herein before stated
preferably fixed at equal distances from each other admitting of equal consecutive
spaces between each plate throughout the length of the carrier plates of sufficient
number being employed according to the width of the doffer or the number of
threads required to be delivered.
As the material in the form of a fleece or sheet travels or passes onto the surfaces
of the plates and over the spaces the said plates being provided conveniently on
their sides with suitable apertures O, Fig 5, being open at its upper part for the
material to enter the outer sides of the aperture projecting into the spaces suitably
so as to engage with the material and as the same is drawn over the plates by the
action of the dividing roller a division of the material is consequently effected at
these parts the dividing roller having a motion thus draws or elongates the material
through the eyes or apertures O of the plates; which extends from one side to the
centre thereof thus transmits the material forward on the surfaces of the plates in
a seperate thread to the condenser rubbers before named the operation being then
complete.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The use and the application of an apparatus herein before specified to be
placed at a convenient part of the stripper or between the stripper and the
condenser rubbers of a single rubber condenser carding engine substantially for the
purpose herein set forth.
2. In apparatus to be applied to single rubber condenser carding engines the
combination of the dividing roller, H. the dividing plates G the carrier E. the
bracket I the brackets, J. J. the wheels L and M substantially as and for the
purposes herein fully set forth and described in the annexed drawings.
