I, WILLIAM KNOWLES of Hartford Mill, Great Lever, and Round Hill Mills,
Bolton, both in the County of Lancaster, Cotton Spinner, do hereby declare the nature
of my said invention to be as follows.
-
This invention relates to carding engines employed in preparing cotton and other
fibrous substances and consists in providing means for more effectually cleaning and
improving the quality of the fibrous substance under operation than hitherto. This I
accomplish by dividing the endless lattice of revolving flats into two sections, the
first section being constructed with flats of coarse open filletting, by the use of which
dirt and other imperfections are more easily arrested, gathered or removed from the
fibrous substance when the latter is passing between the same and the filletting of
the carding cylinder. This section of the endless lattice of revolving flats is
mounted on suitable pulleys and centres, and is guided on the bend or other
equivalents in the usual manner. When the flats are passing the underside of the
bottom pulley near the "taker-in" they are guided-for a certain distance-in a
parallel line to facilitate stripping which is effected by a revolving brush or filletted
roller or its equivalent. The strippings removed by this revolving brush or filletted
roller, or its equivalent are cleared therefrom by another brush or filletted roller or its
equivalent, which delivers them to the "taker-in." The aforesaid strippings are
then passed through the usual operation performed by the "taker-in," and the dirt and
other imperfections which have been caught or arrested by the first section of
revolving flats as before described-will probably in most cases be driven by the
centrifugal force of the "taker-in" into the "fly-space" underneath the same; but
assuming some of the dirt or imperfections should not be so driven into the "fly-
space" they will again be arrested by the first section of revolving flats, and so
process already described will be repeated until eventually the dirt and imper-
fections are deposited in the "fly-space" underneath the "taker-in." The carding
cylinder is protected from the clearing rollers or brushes by a suitable plate or its
equivalent. The second section of revolving flats are divided on the upper side of the
carding cylinder by a plate or its equivalent which extends across the cylinder from
the

page_text: side to side. The second section of revolving flats are constructed and mounted in
the usual manner, and are provided with filletting of fine wire which operates on the
purified fleece in a more effectual manner and produces superior sliver than hitherto.
The first named set of revolving flats can be driven at a greater speed than the
finisher flats or otherwise. The revolving flats and clearer brushes or rollers can be
driven in the usual manner or by other suitable mechanical-means.

Improvements in Carding Engines.
I, WILLIAM KNOWLES of Hartford Mill, Great Lever, and Round Hill Mills,
Bolton in the County of Lancaster, Cotton Spinner, 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:-
This invention relates to carding engines employed in preparing cotton and other
fibrous substances and consists in providing means for more effectually cleaning and
improving the quality of the fibrous substance under operation than hitherto. This I
accomplish by dividing the endless lattice of revolving flats into two sections, the
first section being constructed with flats of coarse open filletting, by the use of which
dirt and other imperfections are more easily arrested, gathered or removed from the
fibrous substance when the latter is passing between the same and the filletting of
the carding cylinder. This section of the endless lattice of revolving flats is mounted
on suitable pulleys and centres, and is guided on the bend or other equivalents in the
usual manner. When the flats are passing the underside of the bottom pulley near
the "taker-in" they are guided-for a certain distance-in a parallel line to facilitate
stripping which is effected by a revolving brush or filletted roller or its equivalent.
The strippings removed by this revolving brush or filletted roller or its equivalent are
cleared therefrom by another brush or filletted roller or its equivalent, which delivers
them to the "taker-in." The aforesaid strippings are then passed through the usual
operation performed by the "taker-in," and the dirt and other imperfections which
have been caught or arrested by the first section of revolving flats-as before
described will probably in most cases be driven by the centrifugal force of the
"taker-in" into the "fly-space" underneath the same; but assuming some of the

page_text: dirt or imperfections should not be so driven into the "fly-space" they will again
be arrested by the first section of revolving flats, and so the process already
described will be repeated until eventually the dirt and imperfections are deposited
in the "fly-space" underneath the "taker-in." The carding cylinder is protected
from the clearing rollers or brushes by a suitable plate or its equivalent. The second
section of revolving flats are divided on the upper side of the carding cylinder by a
plate or its equivalent which extends across the cylinder from side to side. The
second section of revolving flats are constructed and mounted in the usual manner,
and are provided with filletting of fine wire which operates on the purified fleece in
a more effectual manner and produces superior sliver than hitherto. The first-named
set of revolving flats can be driven at a greater speed than the finisher flats or
otherwise. The revolving flats and clearer brushes or rollers can be driven in the
usual manner or by other suitable mechanical means.
Fig. 1 is a part sectional longitudinal elevation showing so much of a carding
engine as is necessary to show my invention and the manner in which it is to be
performed.
A is the carding cylinder; B the "taker-in;" C the "doffer;" D the lap of
cotton or other fibrous substance, and E the framing.
The endless lattice of revolving flats is divided into two sections; the section F is
constructed with the flats G provided with the coarse open filletting H for the purpose
of more easily arresting, gathering, or removing dirt and other imperfections from
the fibrous substance when the latter is passing between the same and the filletting I
on the carding cylinder A. The section F of the endless lattice of the revolving flats G
is mounted on the pulleys J and J' on the centres K; the latter being mounted in
the adjustable supports L attached to the framing M, the flats being guided in the
usual manner on the bend or its equivalent. When the flats G are passing the under-
side of the pulley J near the "taken-in" B they are guided in a parallel line or
tangentially over the revolving brush or filletted roller N by the fixing or guide O
shown in Fig. 2; the latter being attached to the adjustable support L.
The flats & are guided in a parallel line or tangentially to the circle or circumference
of the brush or roller N by the fixing or guide Ŏ over the brush or roller N to allow
of the said flats being stripped of "fly," dirt, and other imperfections before they
operate on the fibrous substance passing over the filletting I on the carding
cylinder A. The strippings removed by the revolving brush or filletted roller N are
cleared therefrom by the brush or filletted roller P, the said strippings being removed.
from the roller P by the "taker-in" from whence they pass again to the carding'
cylinder and so on as often as returned by the flats G to the clearer brushes or filletted
rollers N and P and the "taker-in" B. The dirt and other imperfections which
have been caught or arrested by the revolving flats G in the section F will probably
in most cases be driven by the centrifugal force of the "taker-in" into the "fly-
space" R underneath the same; but assuming some of the dirt or imperfections
should not be so driven into the "fly-space" R they will again be arrested by the
flats G, and so on, the process being repeated until eventually they are deposited in
the "fly-space" R underneath the "taker-in" B.
The flats G of the section F can be driven or traversed at a greater speed than the
finisher flats V or otherwise as desired.
The filletting 1 of the carding cylinder A is protected from the rollers or brushes N
and P by the plate S, which is attached to the framework in any convenient manner.
The section T of the revolving finisher flats V is constructed in the usual manner, and
the flats are provided with the filleting W of fine wire which operates on the purified
fleece in a more effectual manner and produces a superior sliver than hitherto."
The sections F and T of the revolving flats are divided on the upper side of the carding
cylinder A by the plate X or its equivalent which extends across the cylinder Å
from side to side, being secured to the framing in any convenient manner according
to the construction of the carding engine.
Fig. 3 is a part sectional longitudinal elevation of a modification of my invention
wherein I dispense with the clearer brushes or filletted rollers N and P, the revolving

page_text: flats G in the section F being stripped by the "taker-in" itself. This 1 accomplish
by disposing the pulley J and centre K at a lower level so as to bring the filletting H
of the flats G almost into contact with the filletted or spiked surface of the " taker-
in.". To ensure the flats G being stripped perfectly they are passed over the "taker-
in" in a parallel line or tangentially to the circle or circumference of the latter by
the adjustable fixings or guides O shown in Fig. 4, which are fitted on each side of
the carding engine. The strippings removed by the "taker-in" are then passed
through the usual operation performed by the "taker-in" and so on as before
described. The plate S in this case is substituted by the V piece Z. The fixings or
guides O can be adjusted by the screw Y mounted in the fixing or support L carrying
the centres K at each side of the carding engine for the purpose of adjusting the
working position of the filletting H on the flats G to compensate for wear.
revolving flats G and V and the clearer brushes or filletted rollers N and P can be
driven in the usual manner or by other well-known mechanical means.
The
. Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. For stripping "fly," dirt, and other imperfections from revolving flats employed
in carding engines the construction and arrangement of apparatus consisting of the
revolving brushes or filletted rollers N and P, the latter roller being employed for
stripping the revolving brush or filletted roller N ; the roller P being stripped by the
"taker-in" B, substantially as described and as shown on the drawings in Figs. 1
and 2.
2. Stripping revolving flats employed in carding engines by means of the "taker-
in" B, applied and operating substantially as described and as shown on the drawings
in Figs. 3 and 4.
3. Guiding the revolving flats employed in carding engines in a parallel line or
tangentially to the circle or circumference of the brush or roller N or the "taker-
in "B by means of the adjustable fixings or guides O to allow of the revolving flats
being stripped of "fly," dirt, and other imperfections, substantially as described and
as shown on the drawings.
