Improvements in Means for Preventing the Accumulation and
Incorporation of Fluff, Dust, and Short Waste Fibres in or with
Fleeces, Webs, Slivers, and Yarns, the said Improvements being
applicable to Machinery or Apparatus Used in the Preparation
and Spinning of Textile Fibrous Materials.
We CHARLES BUTTERWORTH of 17 Queens' Road, Oldham, in the County of
Lancaster, Mill Manager, and JOSEPH BOWKER of Hope House, Kersal,
Manchester, in the same county, Cotton Spinner, do hereby declare the nature of
this invention to be as follows:-
Our said invention is applicable to machinery or apparatus used in the preparation
and spinning of textile fibrous materials and consists generally of improved means
for automatically preventing the accumulation and incorporation of fluff, dust,
short fibres and other waste matters in or with fleeces, webs, slivers and yarns, as
these pass through the machine.
For example referring to the ordinary cotton carding engine, as the doffed fleece
passes into the draw box, fluff, short fibre and the like is apt to accumulate at the
trumpet or orifice into which the fleece is drawn to form a sliver. These
accumulations of fluff are apt from time to time to be drawn into the trumpet and
to be incorporated with the sliver, thereby causing uneven places or lumps in the
sliver and importing short fibres which are extremely detrimental and cause endless
trouble in the subsequent preparing and spinning operations..
To overcome this defect we place a revolving plate in front of the trumpet or
orifice, or incorporate such a plate therewith the said plate having a central' hole
through which the fleece is drawn to the draw box. The plate is revolved in any
convenient manner but we prefer to rotate it by forming on the back thereof a
worm wheel which engages with a worm driven from any suitable moving part of
the mechanism. The plate is thereby slowly revolved and the fluff or short fibre
and dust as it settles on the surface of the plate is removed by a finger or by a
revolving roller. As the accumulation of fluff is very gradual we might in some
cases dispense with the said removing finger or revolving roller and allow the fluff
to be carried back into the fleece which at the slow rate it accumulates would not
be materially detrimental to the fleece and sliver.
Instead of or in addition to placing the said revolving plate in line with the
trumpet or entrance to the draw box, we might place such a revolving plate above
the trumpet of the coiler top into which the sliver is led to be coiled in the can.
The objection already stated with reference to the draw box exists bere also,
for the sliver as it proceeds to the trumpet, deposits fluff and dust which accumulates
and are from time to time drawn into the trumpet with the sliver, creating the
lumps and inequalities which so injuriously affect the yarn afterwards produced
from the sliver. The aforesaid revolving plate is connected to and revolves with
the trumpet and the fluff gathering on the plate is either continuously passed into
the sliver, or it is licked off or removed from the plate by a revolving roller or by
a finger or jet of air or other contrivance convenient for removing the fluff from
the plate. We also adapt our invention for use in conjunction with a drawing
frame for instance, in which generally speaking the sliver passes through a trumpet
D

page_text: between the drawing rollers and the calender rollers. The sliver on its way to the
trumpet passes over a plate or breast beam filling up the space between the sets of
rollers and on this beam or plate and on the flange of the trumpet the aforesaid
fluff and dust usually accumulates and is from time to time drawn in with the
sliver. To clear away the fluff and dust as it accumulates we might use the
revolving plate and clearing finger or roller as described or we might arrange a
roller of wood, metal, metal tubing or other suitable material covered or uncovered
and arranged to revolve at or near the point where the accumulation takes place.
Such rollers might be used alone or in conjunction with the revolving plate
aforesaid. The rollers pick up the fluff and short fibres instead of allowing these
to be drawn through the trumpet. The rollers may from time to time be stripped
by hand or we might provide strippers to remove the fluff as it is picked up by
the rollers.
Although we have mentioned the carding engine and drawing frame as two
typically useful applications of our invention we do not confine ourselves thereto
as it will be evident that the invention is applicable to all textile fibre preparation
machinery in which fleeces, slivers or yarns are drawn through consolidating
orifices, trumpets or the like and in which it is desirable to prevent accidental
incorporation of fluff, short waste fibre and the like with the fleece, sliver or yarn
as herein set forth.

Improvements in Means for Preventing the Accumulation and
Incorporation of Fluff, Dust, and Short Waste Fibres in or with
Fleeces, Webs, Slivers, and Yarns, the said Improvements being
applicable to Machinery or Apparatus Used in the Preparation
and Spinning of Textile Fibrous Materials.
We CHARLES BUTTERWORTH of 17 Queens' Road, Oldham, in the County
of Lancaster, Mill Manager, and JOSEPH BOWKER of Hope House, Kersal,
Manchester, in the same county, Cotton Spinner, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and accompanying
drawings
Our said invention is applicable to machinery or apparatus used in the
preparation and spinning of textile fibrous materials and consists generally of
improved means for automatically preventing the accumulation and incorporation
of fluff, dust, short, fibres and waste matters in or with fleeces, webs, slivers and
yarns as these pass through the machine.
To render our invention fully understood we will now proceed to described
the same more particularly with reference to the annexed two sheets of illustrative
drawings.
On Sheet 1.
Fig. 1 illustrates in vertical section a portion of the draw box mechanism of a
carding engine.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a front view of the draw box plate the ordinary curling plate h
bieng broken away to show the trumpet in the centre of our improved revolving
fluff plate.

On Sheet 2.
Fig. 5 is a vertical section of the cover of the coiler top of a carding engine
through the trumpet of which the sliver is led to be coiled in the can.
Fig. 6 is a plan view of the coiler top.
Fig. 7 is a view on the inner side of the coiler top showing the drawing
rollers.
Fig. 8 is a similar view with the rollers removed to show the skew toothed or
worm wheel by which the fluff plate is revolved.
Fig. 9 is an elevation of one of the front plates of a drawing frame upon which
our improved fluff clearing roller is mounted.
Fig. 10 is a plan of Fig. 9.
Referring in the first place to Figs. 1 to 4, a indicates the front plate of the
carding engine draw-box mechanism, mounted as usual on the cross stay h
Behind this plate are situated the drawing rollers c c. Our improved revolving
plate for automatically. preventing the accumulation of fluff and loose fibre is
marked d. In the centre of the plate d is the orifice or trumpet e through which
the fleece is drawn to form a sliver. Under ordinary conditions when there is
no revolving plate d and fluff, short fibre and other refuse is apt to accumulate
near and around the trumpet mouth e. These accumulations are apt from time to
time to be drawn into the trumpet and incorporated with the sliver, thereby
causing uneven places or lumps in the sliver and importing short fibres, which
are extremely detrimental and cause endless trouble in the subsequent preparing
and spinning operations. It is to overcome these defects that we have devised the
revolving plate d. As plainly shown in the drawings the front plate a is cut out
to admit the plate carrier d' the said carrier consisting of a circular toothed rack
capable of revolving in the gap in the plate a and held therein by catches
(see Fig. 4) the ends of which enter a groove in the periphery of the carrier d¹.
Thus the carrier d' with its attached plate d is practically supported as in
bearings. Arms d² carry the central boss e which constitutes the trumpet in
the centre of the revolving plated. The carrier and plate are revolved by the
following means.
The under or driven roller c' has on its axle c² a toothed wheel i which
gears into a similar toothed wheel on an intermediate stud j. On this same
intermediate stud j is a toothed pinion which gears with a toothed wheel
on a separate carrying stud k. The wheel gears with the circular toothed
rack on the carrier d¹. Thus motion is transmitted from the calender roller c¹
to the revolving plate d.. We do not however confine ourselves to this particular
mode of driving the plate d, for example a worm and worm rack or wheel might
be used. By these or by other suitable means the plate d is slowly revolved
and the fluff as it settles upon the plate or round the trumpet mouth is at once
and before it has time to accumulate or form any bulk, carried back into the
fleece or sliver f. We might however if desired use in conjunction with the
said revolving plate a fixed clearing finger or revolving roller to pick up and
retain the fluff and dust without allowing it to return to the fleece.
Referring now to the figs. on Sheet 2. Figs. 5 to 8 illustrate our invention
as applied to the coiler top of a carding engine. As in the case of the draw-box
mechanism plate a, the cover of the coiler top is cut out to admit the carrier d¹
to which the revolving plate d is secured by screws d2 (see Fig. 8)..
In the centre of the plate d is the trumpet mouth e through which the sliver is
drawn by the calender rollers m m¹ (see Fig. 7). These calender rollers are driven
in the ordinary manner, and on the axle of the roller m, is a worm m³ which gears
with the skew teeth formed on the plate carrier d'. The carrier d' is secured
so as to revolve in the cover by means of the catches g just as in the case of the
plate carrier already described with reference to Sheet 1. By the indicated
worm and skew teeth arrangement the plate d is slowly revolved as the sliver ƒ is

page_text: .
drawn across it and through the trumpet e (see Fig. 6). As the plate d revolves,
the fluff, short fibre and other matters settling on the plate are carried round and
into the sliver which takes them forward with regularity and before they have
time to collect or accumulate. We might however in conjunction with the
revolving plate d use a fixed clearing finger such as is indicated by the dotted
lines marked n, in Fig. 6.
This finger would pick up and accumulate the fluff as the plate revolved and
could be cleared from time to time by hand.
In either of the foregoing examples we might arrange for the central trumpet
mouth e to be stationary while the plate revolved. This might be necessary in the
case of very fine and delicate slivers or fleeces which would not readily withstand
the twisting action of the revolving trumpet mouth.
In the coiler top arrangement we might (as shown in Fig. 8A) place beneath
the revolving plate d a secondary plate o which might be covered with flannel or
other fabric. This plate o is centred on the trumpet e and rests in contact with
the calender rollers m, m', thereby acting as a clearer to the said calender rollers.
Either the draw box plate or the coiler top plate might be used in a carding
engine or both might be used in combination. The revolving coiler top plate d
might be driven by toothed gearing instead of by a worm as described.
We also adapt our invention for use in conjunction with a drawing frame in
which generally speaking the sliver passes through a trumpet in a breast plate
between the drawing rollers and the calender rollers. This adaptation is shown in
Figs. 9 and 10.
The sliver on its way to the trumpet e after leaving the drawing rollers (not
shown in the drawings) passes over a plate or breast beam p at the front of the
frame, and just over the calender rollers g. On this breast beam p and on the
flange of the trumpet, the fluff and dust usually accumulates and is from time to
time drawn in with the sliver in the form of an inequality or lump. To clear away
the fluff and dirt as it accumulates we use a roller ŕ of wood, metal tubing or other
suitable material, covered with fabric or uncovered and arranged to revolve at or
near the point where the accumulation takes place. The roller is furnished with
gudgeons at each end which run in slots in brackets s secured to the breast
beam p.
At one end of the roller r one of the gudgeons carries a friction
wheel which bears upon the revolving axle q' of the calender rollers q.
clearing roller is revolved on the breast beam p and picks up the accumulating
fluff and dust which would otherwise be drawn in by the sliver.

Thus the
The rollers may from time to time be stopped by hand or we may provide
strippers to remove the fluff as it is picked up by the rollers. Such rollers
might be used alone with the usual plain breast beam p or they might be
applied in combination with revolving plates such as d, mounted in the breast
beam.
Although we have referred to the carding engine and drawing frame as two
typically useful applications of our invention we do not confine ourselves thereto
as it will be evident that the invention is applicable to all machinery used in the
preparation of textile fibres, in which fleeces, slivers or yarns are drawn through
consolidating orifices, trumpets or the like or in which it is desirable to prevent
lumps and inequalities from becoming incorporated with the fleece, sliver or
yarn, or to obviate the accumulation of fluff and the like at
consolidating parts.
