Improvements in Machinery or Apparatus for Cleansing and
Lustreing Dyed or Undyed Yarns of Silk, Cotton, or other
Fibrous substances.
We, SHARPLES FISHER, of Longroyd Mills, Huddersfield, in the County of
York, Silk Spinner, and HERBERT MURGATROYD, of Yews Lane, Lockwood,
near Huddersfield, aforesaid, Silk Carder, do hereby declare the nature of this
invention to be as follows:-
This invention relates to machinery or apparatus employed for cleaning and
lustreing dyed or undyed yarns of silk, cotton, or other fibrous substances.
According to the present method of cleaning and lustreing silk yarns, the
threads are unwound from one bobbin onto another, but between the said bobbins
the yarn passes over or around a series of vertical rotating cones attached to a
stationary part of the machine; the said threads also, on their way to the winding
on bobbin, passing through a niche or between two rubbing surfaces also connected
to a stationary part of the machine and finally onto the winding-on bobbin, onto
which they are guided through a similar niche fixed on a traversing bar for the
purpose of permitting the yarn to be wound laterally thereon. To the use of the
niches there is great objection, because loose fly accumulates therein, and when so
accumulated, is being continuously removed by the travelling yarn to which it
adheres, thereby forming objectionable lumps or knotty looking places thereon; and
in consequence of one set of guiding niches being stationary and the other set of
guiding niches traversing backwards and forwards in an endwise direction the yarn
is being constantly placed at an acute angle which renders it unable to bear the
same drag or tension as it could bear if in a straight condition, thus limiting the
drag (so necessary for cleaning purposes) which could otherwise be put on the yarn.
The said travelling yarn also passes over one or more flames of gas for the purpose
of burning off projecting fibres; but in practice it is found that the use of gas
discolours the yarn, making it necessary, in some instances, for the said yarn to be
washed, whereas by our invention, we can obtain a better result without washing.
According to our invention the conical tubes or cones are attached to a pivotted
radial arm which has imparted to it by cam, or other well known device, an
oscillating or pendulous movement which traverses the yarn over the barrel of the
bobbin By this means the travelling yarn taken in a direct line, or nearly direct
line, from the unwinding bobbin to the winding-on bobbin, so that the acute angles
mentioned above are avoided, consequently considerably more drag or tension can
be put upon the yarn than formerly, whereby the increased pressure or drag of the
yarn around the cones enhances the cleaning or lustreing thereof; and in order to
remove the fly or fluff which gathers on the cones, we employ a rotating brush
arranged parallel with the said cones so as to wipe or remove the fluff therefrom,
by which means the cones are kept continuously clean, and a clean yarn produced.
In order to regulate the tension of the unwinding bobbin to suit the varying counts
of yarn being cleaned, we employ a ratchet wheel and catch in connection with
each of such bobbins, which allows the tension to be adjusted accordingly.
Our invention in cleaning and lustreing machines is equally applicable whether
gas is employed therein or not.
By means of our invention the flames of gas are dispensed with when necessary,
and also the guides or useless rubbing surfaces which, in some cases of dyed yarns,
burnish the yarn in an objectionable manner, this improvement being effected by

page_text: reason of the yarn now being carried direct from conical tubes or cones to the
receiving bobbins, without the said intermediate niches or guides.

Improvements in Machinery or Apparatus for Cleaning and
Lustreing Dyed or Undyed Yarns of Silk, Cotton, or other
Fibrous substances.
We, SHARPLES FISHER, of Longroyd Mills, Huddersfield, Yorkshire, Silk
Spinner, and HERBERT MURGATROYD of Yews Lane, Lockwood, near Hudders-
field aforesaid, Silk Carder, 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: --
This invention relates to machinery or apparatus employed for cleaning and
lustreing dyed or undyed yarns of silk cotton or other fibrous substances.
According to the present method of cleaning and lustreing silks yarns the
threads are unwound from one bobbin on to another but between the said bobbins the
yarn passes over or around a series of vertical rotating cones attached to a stationary
part of the machine, the said threads also on their way to the winding-on bobbins,
passing through niches or between two rubbing surfaces also connected to a
stationary part of the machine and finally onto the winding-on bobbins onto which
they are guided through similar niches fixed on a traversing bar for the purpose of
permitting the yarn to be wound laterally thereon. To the use of the niches there
is great objection because loose fly accumulates therein and is continuously removed
by the travelling yarn to which it adheres and forms thereon objectionable lumps
or knotty looking places, and in consequence of one set of guiding niches being
stationary and the other set of guiding niches traversing backwards and forwards
in an endwise direction, the yarn is being constantly placed at an acute angle which
renders it unable to bear the same drag or tension as it could bear if in a straight
condition, thus limiting the drag—so necessary for cleaning purposes-which could
otherwise be put ou the yarn.
The said travelling yarn also passes over one or more flames of gas for the
purpose of burning off projecting fibres, but in practice it is found that the use of
gas discolours the yarn, making it necessary, in some instances, to wash the yarn
whereas by our invention, we can obtain a better result without washing.
According to our invention the conical tubes or cones are attached to pivotted
radial arms having oscillatory or pendulous movement imparted thereto, which
traverse the yarn over the barrels of the bobbins, by which means the yarn is
taken in a direct or nearly direct line from the unwinding bobbins to the winding-on
bobbins so that the acute angles above mentioned are avoided, and considerably.
more drag or tension can be put upon the yarn, the increased pressure or drag of
the yarn around the cones enhancing the cleaning or lustreing thereof.
A brush is employed in connection with each radial arm to wipe or remove the
fluff or fly from the cones and to prevent it adhering to the travelling yarn.
In order that our invention may be more fully understood reference is herein
made to the accompanying sheets of drawings illustrative thereof :-
Fig. 1 is front elevation of so much of a machine for cleaning and lustreing yarns
as is necessary to shew our improvements therein;
Fig. 2 is cross section and Fig. 3 plan of same.
a is the framework of the machine, the main shaft having mounted thereon
grooved pulleys c which, by means of cords d, give rotary motion to the winding-on
bobbins e; a second shaft 61 (see Fig. 3) driven by gearing from the shaft band
carrying grooved pulleys c¹ being employed to give motion, through cords d¹ to the

page_text: winding-on bobbins at the opposite side of the machine. f is a cross shaft
supported in bearings in the bracket g at the end of the machine, said shaft receiving
rotary motion from shaft b by bevils h, worm and worm wheel /². Mounted on
the shaft is a cam i engaging with a friction bowl k secured on a stud projecting
from the lever which is pivotted at its lower end to the bracket k² and attached
at the upper end to the longitudinal bar / supported on friction runners or rollers m
carried in brackets m¹ bolted to the top rail of the machine.
The rotation of the cam i gives an oscillatory or rocking motion to the lever k¹
which traverses the longitudinal bar to and fro in an endwise direction continuously..
The bowl k is kept in contact with the cam by weight suspended at the end of
the chain which passes around a pulley on the shaft and is connected to the
stud on which the bowl is mounted. The cam also mounted on shaft, by means
of a second lever, operates the longitudinal bar at the opposite side of the machine
in the same manner as previously described.
n represents the radial arms provided with steel pins upon which are placed
loosely the cones o. The front ends of the said radial arms rest upon the longi-
tudinal traversing bar and are placed between and held in position by the
adjustable stop pieces and the base of the brackets n2 both secured to the
traversing bar so that as the latter moves endwise to and fro it carries with it
the arms n which, being secured at the opposite or rear ends in the pivotted yokes
or brackets n³, are thereby caused to oscillate in the manner and to the extents
indicated by the broken lines in Fig. 3.
The yokes n are provided with studs p resting in the fixed footsteps p' which
form hinges or pivots to said yokes and permit of same moving round in a hori-
zontal plane, the radial arms_n being secured in the yokes by pins which enable
said arms to be raised or lifted up for cleaning or other purposes.
indicates the brushes which are arranged parallel to the radial arms and
supported at one end in bearings in the brackets 2 fixed to the traversing bar and at
the opposite end in bearings n forming part of the pivotted yokes n³. The said
brushes are driven by cords or straps from the shaft ², those at the opposite
side of the machine being driven in like manner from the shaft 3 which receives
its motion by cord or strap from the shaft and transmits motion to the shaft,2
by toothed wheels. The speed pulleys s allow of variation in the speed at which
the brushes shall be driven.
The unwinding bobbins t are supported in brackets & bolted to the rail t2, and are
of the same size as the winding-on bobbins e so as to be interchangeable therewith
in order that the latter, when full, may be taken from the front of the machine
and placed in the brackets t and replaced by the bobbins from which the yarn
has been unwound with the least possible trouble, this being very advantageous
when the yarn must be traversed through the machine several times.
The bracket is provided with a slot as is also the upper end of the lever
in order that the traverse of the bar may be altered or varied as desired and
the parts adjusted.
The action of the machine is as follows:-
The yarn from the unwinding bobbins t is passed under the guide rod v and.
thence onto the cones o around each or some of which it is passed once and is
finally conducted onto the winding-on bobbins e. The winding-on bobbins are
preferably supported in hinged brackets e' so that when commencing to wind on
the yarn the bobbin shall not be started too suddenly. This is effected by
gradually raising the brackets from the position shewn in dotted lines to that shewn
in full line in the drawings and therefore gradually tightening the cords d around
the wharles e² the said brackets being held in the position shewn by any suitable
form of catch.
The rotation of the winding-on bobbins draws the yarn off the unwinding
bobbins and around the cones which are rotated thereby, the oscillatory or
pendulous movement of the arms n winding or traversing the yarn after it leaves
the cones backwards and forwards over the barrel of the bobbins by which means

page_text: the yarn is not placed at an acute angle during any part of its traverse but is taken
in a direct or nearly direct line from the unwinding bobbins to the winding-on
bobbins and consequently more drag or tension can be put upon the yarn.
The
increased pressure or drag of the yarn around the cones which we are thus enabled
to obtain enhances the cleaning or lustreing thereof.
The loose fly or fluff as it forms is removed off the cones by the rotating brushes r,
which, having the same pendulous or oscillatory motion as the radial arms are
always in contact with the cones thereby keeping them clean and preventing the fly
adhering to the yarn which is consequently cleaner and free from lumps or knotty
looking places. Instead of the brushes being rotated, they may be reciprocated or
rocked, any suitable mechanism being employed for this purpose.
The drag or tension is put on the yarn by means of the cord w and weight w¹,
the cord being attached to a peg w² which is inserted into one of the holes a on the
inner side of the bracket t and the cord passed over the wharle of the bobbin so as
to act in the manner of a brake thereon. The tension or drag is regulated to suit
the varying counts of yarn being cleaned by inserting the peg w² in one or other
of the holes so that more or less cord lies upon the wharle.
The improvements above set forth are equally applicable whether gas is or is
not employed, such gas by means of our invention being dispensed with when
necessary. The guides or useless rubbing surfaces which in some cases of dyed yarn,
burnish it in an objectionable manner are also disposed of.
Having now fully described and ascertained the nature of our invention
and the manner in which the same is to be carried into effect, we declare that
what we claim is
Firstly. In machines for cleaning and lustreing dyed or undyed yarns of silk,
cotton or other fibrous substances, the pivotted radial arms n having oscillatory or
pendulous movement imparted thereto for traversing the yarn in a direct or nearly
direct line from the unwinding bobbins to the winding-on bobbins and winding it
laterally upon the said winding-on bobbins in the manner and for the purposes
substantially as herein shewn and described.
Secondly. In machines for cleaning and lustreing dyed or undyed yarns, the
combination with the radial arms a provided with pins carrying cones o and means
for imparting oscillatory or pendulous movements to said arms, of brushes » operated
in the manner and for the purposes substantially as herein set forth.
Thirdly. In machines for cleaning and lustreing dyed or undyed yarns, the
combination with the pivotted radial arms carrying cones o, operated in the manner
and for the purposes herein set forth, of the means for giving and regulating the
drag or tension on the yarn substantially as described.
