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, 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
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 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 pecessary 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 yarn is made to pass in a straight or nearly
straight line from the unwinding to the winding-on bobbin without coming in contact
with any eye or niche (excepting in the case of one arrangement of the machinery
hereafter described) thereby securing the entire amount of obtainable friction for
the purposes of cleaning or lustreing, and at the same time keeping the yarn from
contact with any rubbing surface or surfaces after it leaves the runners (which is
not the case in the present system) and which contact is injurious to some kinds of
yarn.
To effect this object we place either a suitably shaped bar or a pivotted radial
arm to which are attached the conical tubes, cones, or runners between the unwinding
and the winding-on bobbins; the oscillating or pendulous movement of the said
radial arm being given by cam, crank, or other well known device.
The winding-on bobbin can be used either in an upright or horizontal position and
be made to revolve and traverse endwise or to revolve only.
The radial arm may be pivotted at either end or other suitable part of the arm,
so as either to traverse the yarn onto a fixed winding-on bobbin, or to carry the
yarn from an unwinding bobbin which shall traverse in a straight line with the
radial bar onto a winding-on bobbin which shall also traverse.
'
Or, the unwinding bobbin may be fixed and the winding-on bobbin made to
traverse, in which case the yarn must pass through an eyelet or guide.

page_text: Or, the said bar can be made to traverse at right angles to the winding-on bobbin,
which in this arrangement would be fixed.
Or, the said bar may remain stationary, and the winding-on bobbin be made to
traverse.
By any of the above arrangements we can arrive at the same or almost the same
result.
In order to remove the fly or fluff which gathers on the cones, we employ a
rotating or oscillating 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 or a notched
bracket 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.

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, 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
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 silk yarns, the threads
are unwound from one bobbin outo 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 and also through a niche or between two rubbing surfaces also
connected to a stationary part of the machine, the yarn being finally guided onto
the winding-on bobbin through a similar niche fixed on a traversing bar which
causes said yarn to be traversed laterally onto the barrel of the bobbin. To the
use of the niches there is great objection because loose fly accumulates therein and
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 traversing backwards
and forwards, the yarn is constantly being placed at an acute angle which renders it
unable to bear the same drag or tension 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.
According to our invention the yarn is made to pass in a straight or nearly
straight line from the unwinding to the winding-on bobbin without coming in contact
with any eye or niche, thereby securing the entire amount of obtainable friction for
the purpose of cleaning or lustreing. The yarn is also kept clear of any rubbing
surface or surfaces after it leaves the runners.
For the purpose of more fully explaining our invention, reference is hereinafter
made to the accompanying sheet of drawings illustrating our invention and shewing
various methods of traversing the yarn laterally on the barrel of the winding-on
bobbin.
:

page_text: Fig. 1 is side elevation of so much of the apparatus or machine as is requisite to
shew our improvements.
+
a denotes the radial arm provided with the vertical conical tubes or runners b
supported loosely on pins projecting from the face of the radial arm, around which
tubes, or some of them, the yarn y travels on its way from the unwinding bobbin e
to the winding-on bobbin d. The winding-on bobbin d is mounted in an upright
position on a spindle e driven by cord f, or it may be supported in bearings in a
suitable bracket bolted to the frame g. The radial arm is pivoted at hand is
oscillated up and down-as indicated by broken lines-by a rail or bar i so as to
traverse the yarn over the barrel of the winding-on bobbin, the said rail or bar
being actuated by cam, crank or other well known mechanical device, or the cam or
crank may act direct on the radial arm. A rotating brush j carried in bearings k
and oscillating with the radial arm is employed to keep the cones or tubes >> clean
and free from fluff.
Instead of oscillating the radial arm, the rail carrying the spindle e of the
winding-on bobbin, may be caused to move in an endwise direction horizontally, or
to rise and fall in the same manner as the lifting rail in a spinning or twisting frame,,,
the horizontal endwise movement or the rise and fall of the bobbins d causing the
yarn to be wound onto the barrel thereof from end to end. The same results are
also obtained by mounting the winding-on bobbin in a horizontal position and causing
the radial arm to oscillate in a horizontal instead of a vertical plane..
In plan view Fig. 2 the radial arm is pivoted at h either midway of its length as
shewn, or nearer to one end than the other, and the winding-on bobbin is carried in
a bracket secured to a reciprocating rail operated by cam m or other similar
device. The radial arm is also oscillated by cam or crank, its front end always
moving in the opposite direction to the end wise traverse of the winding-on bobbin
so that the yarny may be distributed equally and evenly over the barrel of the said
bobbin. The unwinding bobbin c may be fixed, or it may be reciprocated in the
same way as the winding-on bobbin d although this is not necessary to the result to
be obtained.
In plan Fig. 3 the radial arms are secured to a frame n as are also the unwinding
bobbins c, and the said frame is caused to reciprocate or move endwise as indicated
by the arrows, by means of cams cranks or other devices so as to traverse the yarn y
laterally onto the fixed winding-on bobbins d. Instead of the radial arms and
unwinding bobbins being reciprocated bodily as explained, they may be fixed and
the winding-on bobbins d made to traverse endwise backwards and forwards.
By any of the above arrangements and methods we can arrive at the same or
almost the same results and in each case the yarn is conducted from the unwinding to
the winding-on bobbins in a straight or nearly straight line without encountering
any friction between useless rubbing surfaces or guide eyes, but securing the entire
amount of friction on the conical tubes required for cleaning and lustreing the yarn.
In order to regulate the tension of the unwinding bobbins to suit the varying
counts of yarn being cleaned, we employ a cord o carrying a weight p, and attached
to a pegadapted to fit into the holes s formed in the bracket carrying the unwinding
bobbin. The cord o passes over the wharle or pulley on the end of the unwinding
bobbin and forms a brake thereto. The drag or tension is adjusted by inserting the
peg into one of the holes s either nearer to or further from the vertical centre of
the bobbin, so that a less or greater length of cord lies on the surface of the wharle.
Our invention in cleaning and lustreing machines is equally applicable whether
gas is employed therein or not.
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 methods and means substantially as herein
shewn and described for conducting the yarn in a straight or nearly straight line

page_text: from the unwinding bobbins to the winding-on. bobbins and for traversing the yarn
laterally over the barrels of the said winding-on bobbins for purposes set forth.
Secondly. The combination, with the means for conducting the yarn in a straight
or nearly straight line from the unwinding to the winding-on bobbins and traversing
it laterally over the barrels of said winding-on bobbins of rotating or oscillating 5

yarn substantially as herein shewn and described.
