WINDING YARNS."
PROVISIONAL SPECIFICATION left by the said William Lancaster and
Edward Slater at the Office of the Commissioners of Patents on the 8th
September 1881.
WILLIAM LANCASTER, Machine Maker, of Accrington, and EDWARD SLATER, of
Burnley, both in the County of Lancaster. CERTAIN IMPROVEMENTS IN
MACHINERY FOR SPINNING, Doubling, and WindinG YARNS."
The first part of this Invention relates to what are known as ring spinning
frames or fly throstles, and consists in a novel arrangement of mechanism that
gives motion to what is known as the lifting rail; a heart or cam working
horizontally, or nearly so, by preference in contact with a slide, is connected to a
chain or other flexible band, by which means a direct pull or push is given to the
parts working the rail, and this without the intervention of a first lever, as is now
used.
An adjustable quadrant, wheel, or lever, in connection with the above named
heart and slide, regulates what is commonly called the length of the chase of the
said rails, or the distance of its upward and downward motion.
Again, to this last named adjustable quadrant, wheel, or lever, is attached an
adjustable projecting part, by means of which the motion of the said rail is further
regulated at the commencement of the cop, or when it is working at what is called
the cop-bottom.
This arrangement brings all the first moving parts of the lifting mechanism
within easy access, gives a steadier and more positive motion to the rail, and lfts
much easier than the hitherto existing arrangement, also greatly facilitating the
ordinary operation preparatory to what is called doffing.
The second part of the Invention consists, firstly, in the use of a small ring, or a
portion of one inserted in a suitable circular recess, to which is attached a novel
form of traveller or small flyer, in place of the ordinary traveller.
This novel traveller or flyer is so constructed as to swivel in a radial direction to
and from the cop-spindle or tube, and to come into contact with the said cop-.
spindle or tube in such a manner as to cause the spindle to act as a fulcrum to the
[Price S1

page_text: flyer and its attachments, thus giving the yarn by which it is driven a greater
power over it than it otherwise would have when it is working at the apex of
the cop
Attached to this said traveller or flyer is also a suitable fixed projection, which
by coming in contact with the stationary or other surface of the frame work, acts
as a break upon the flyer's motion, and so tends to retard its motion, and .gives the
necessary drag required to wind the yarn as it is spun.
This object can also be accomplished by having the ring constructed with suitable
points of contact between the said ring and flyer, by which means the ring itself is
somewhat distorted from its circular. form, and made to press against its bearings
with a greater or less amount of friction.
Again, this said traveller or flyer is constructed with a prolonged pivot, around
the upper part of which the yarn can be coiled any suitable number of turns, so as
to prevent the tension that is required to wind a hard cop affecting and damaging
the said yarn as it is delivered from the rollers.
This part of the Invention also facilitates the operation of piecing the broken
yarn or thread. This traveller or small flyer can also be constructed in the form
of a semi-ring with suitable projection for holding it in a circular recess, and for
receiving the coils of yarn, and guiding it to the cop-tube or spindle.
It can also be constructed of two or more rings or parts of rings suitably con-
nected together, or also in the form of a forked shaped dragwire; in short, it may
be made in various shapes, having the necessary projections for holding it in its
place, and for guiding the yarn to the spindle, cop, or tube, and making the same
act as a fulcrum.
Another part of this Invention consists in an improved form of oblong traveller,
whereby a greater degree of stability is given to the same. This is accomplished
by forming the said traveller of two or more loops instead of one. The under loop
is sprung upon what is known as the ring as its base of support, the upper ones.
are to receive the yarn, and act as a guide to the same in. its progress to the
spindle tube, or whatever it is being wound upon. We make this form of traveller
flat by preference, as this gives it a greater power of causing tension upon the yarn
with fewer coils of the same around it, which saves time and labor in piecing. In
this case we make either the spindle, cop, or tube act as a fulcrum, or the outer
line of yarn or thread itself do so, in order to give the yarn or thread as before
mentioned a greater power over the said traveller.
Another part of this Invention consists in adding-an-additional-wharve to the
spindle which acts in the manner of a loose pulley, and greatly facilitates the
stopping of the spindle when the yarn is broken. This may be applied to doubling
spindles so as to prevent single yarn.
Thirdly. Another part of this Invention consists in fixing a longitudinal tube or
cavity running in a line with the frame work and spindles, into which oil or other
lubricant can be stored, and by a corresponding longitudinal shaft with a number
of small wires or other filaments, the said lubricant matter can be conveyed by a
single motion of the said shaft to the spindles and flyers in such quantities and at
such times as may be required to prevent waste, and secure the proper action of
the above mentioned spindles and flyers.
The same object may be accomplished by means of a band saturated with any
lubricating matter lying in a groove in proximity to or in contact with the parts,
and running in a line with the said parts requiring lubrication, or also by an
endless band whch may be stationary or moveable.
This part of the Invention may be applied to existing frames where revolving
spindles, bosses, etc., are used.
Existing spinning mules can be changed to this principle of spinning.
Another part of this Invention consists in a novel costruction of a weight hook
or weight hanger, whereby one or more small balls or bowls placed in the head of
the said hook or hanger tend greatly to lessen the friction betwixt the parts in
contact, that is to say, the hook or hanger and the roller upon which it hangs,

page_text: thereby giving a more uniform surface speed between the bottom and top roller,
and consequently giving a greater degree of equality and regularity to the sliver
delivered 'from the rollers.
The next part of our Invention relates to the formation of cops or bobbins on
what are called winding machines. To accomplish this object we use a spindle,
tube, or boss, so fixed as to be freely moveable on a longitudinal rail, or between
two such rails. The copspindle is formed with a head or cap, and drops into the
said tube or boss loosely. Near this first spindle we place. a secondlone, the top
part of which is formed as a screw, and upon this screw is placed a bowl of wood
or other substance. The lower part of this screw spindle enters a socket which
keeps it in position.
Again, on this screw spindle we place an inverted conical dish, and over this we
fix what we term a winged nut. This nut is so constructed that it can be raised
or lowered at the will of the operator without turning the screw.
.f.
Further, the inverted dish is so placed that its lower part comes into contact
with the cop spindle, or the cop that is on it, and so as the cop is being formed the
bowl or dish is made to rotate intermittently, thus causing the winged nut before
mentioned to shift its position, and carry with it the spindle upon which the 'cop is
formed. This arrangement of screw and nut prevents the yarn being glazed by
rubbing against the dish, bowl, or cup as hitherto used.
Another method of forming cops or bobbins by the aid of the above mentioned
screw spindle, dish, and winged nut, is as follows:-
We place the dish or bowl in a reverse direction, and the cop spindle has a
rotary but not an upward motion. The screw spindle is hollow and is fixed to the
rail;
the dish we now convert into a conical nut, which, nut carries the guide wire.
This conical nut is caused to rotate intermittently by contact with the yarn as it
is being wound on the spindle, which action continues until the cop is full.
Again,. the screw spindle is made hollow to admit of a small wire or other
connection passing through it from the top of the screw to the wharve on the cop
spindle for the purpose of stopping the said spindle when the cop is full.
Another part of this Invention consists in giving the spindles a varying motion,
which is very important in winding tender yarns. We accomplish this by placing
two wheels or pulleys of any suitable diameter in such a manner as to throw their
centres out from each other or excentrical to each other; on what we call the outer
wheel we fit a stud, and on the shaft of the inner wheel a, lever which extends
beyond the periphery of the wheel. In this lever is formed a slot for the reception
of the stud before mentioned. The action of this arrangement is as follows:-The
stud fixed to the outer wheel or wheels working in the slot in the lever communi
cates to the latter a variable motion as it nears to or recedes from the centre, which
motion is conveyed to the tin roller by means of a strap and pulleys.
Our next. improvement consists in an arrangement by which we regulate the
diameter of the cop or bobbin. This is done by placing a heart motion on the
shaft which conveys the variable motion to the spindles. We also fix a pendulum-
like lever suspended from its upper part near the centre of the frame, and on the
end of this lever is a bowl acting on the heart; we attach arms to the said
pendulum-like lever which connect the moving rails on each side with the said
heart motion. In the end of these arms we fix supplementary rods in reversed
positions, having slots in them for the purpose of receiving studs to which the
connecting rods of the first lever are attached. By this arrangement. the diameter
of the cop can be regulated as required. Or further, one side of the frame can be
made to wind one diameter of cop or bobbin, whilst the opposite side.winds.another
diameter.
וי
For the purposes of this Invention and for other purposes we use when required
nanan tube with metallic surface

SPECIFICATION in pursuance of the conditions of the Letters Patent, and of
an Order of the Lord Chancellor, filed by the said William Lancaster and
Edward Slater in the Great Seal Patent Office on the 29th May 1882.
WILLIAM LANCASTER, Machine Maker, of Accrington, and EDWARD SLATER, of
Burnley, both in the County of Lancaster. *CERTAIN IMPROVEMENTS IN
MACHINERY FOR SPINNING, DOUBLING, AND WINDING YARNS."
The first part of this Invention relates to what are known as ring spinning
frames or fly throstles, and consists in a novel arrangement of mechanism that
gives motion to what is known as the lifting rail, which lifting rail or slide bar is
placed edgeway up, by preference, and is constructed to hold a novel kind of eye
bolt with a groove in it to receive a novel spring ring with a spring flyer attached
to it; a heart or cam working horizontally, by preference, in contact with a slide
which is connected to a chain or flexible band, by which means a direct pull or
push is given to the parts working the novel slide bar, and this without the inter-
vention of a first lever as is now used; "an adjustable quadrant, wheel, or lever in
connection with the abové named heart and slide regulates what is commonly
called the length of the chase of the said lifting rail or slide bar, or the distance
of its upward and downward motion.
Again, to this last named adjustable quadrant is attached an adjustable pro-
jecting lever, by means of which the motion of the said slide bar is further regu-
lated at the commencement of the cop, or when it is working at what is called
the cop bottom.
The second part of our Invention consists, firstly, in the use of a small clasped
spring-ring or a portion of a spring ring inserted in a suitable circular recess or
groove of the novel eye bolt, to which is attached a novel form of traveller. This
novel traveller or spring flyer is so constructed as to swivel upon a pivot in a radial
direction to and from the cop, spindle, or tube, and so come in contact with the
said cop, spindle, or tube in such a manner as to cause the spindle to act as a
fulcrum to the flyer and its attachments, thus giving the yarn a greater power
over it than it otherwise would have when it is working at the apex of the cop.
Again, this said traveller or spring flyer is constructed with a prolonged pivot,
around the upper part of which the yarn can be coiled any suitable number of
turns, so as to prevent the tension that is required to wind a hard cop affecting
and damaging the said yarn as it is being delivered from the rollers. This part of
the Invention also facilitates the operation-of-piecing the broken yarn or thread.
This-traveller or small spring flyer can also be constructed in the form of a semi-
ring with suitable projections or bends for holding it in a circular recess, and with
one or more projections or bends for guiding the yarn to the cop, spindle, or tube,
in combination with one or more of our projections or bends for receiving the coils
of yarn, so as to prevent the tension that is required to wind a hard cop from
affecting and damaging the said yarn as it is being delivered from the rollers.
It can also be constructed of two or more rings or parts of rings suitably con-
nected together or in the form of a fork shaped drag wire, combined with our
prolonged pivot, or with one or more of our projections, around which the yarn can
be, coiled any number of turns, so as to prevent the tension that is required to
wind a hard cop from affecting and damaging the said yarn as it is being delivered
from the rollers through our spring guide wires which are placed in grooves on
bars, and which may be moved backwards and forward individually or simul-
taneously. In short, the traveller may be made in various shapes having the
necessary, projection or projections for holding it in its place, and for guiding the
yarn to the cop, spindle, or tube, and making the same act as a fulcrum. We
make this form of traveller or spring flyer flat, by preference, as this gives it a
greater power of causing tension upon the yarn with fewer coils of the same
around it, which saves time and labour in piecing. In this case we make either
the cop, spindle, or tube act as a fulcrum, or the outer line of yarn or thread itself

page_text: do so, in order to give the yarn or thread, as before mentioned, a greater power
over the said traveller or spring flyer.
Another part of this Invention consists in an improved form of oblong traveller,
whereby a greater degree of stability is given to the same. This is accomplished
by forming the said traveller of two or more loops instead of one, the underloop or
spring ring is sprung upon what is known as the ring as its base of support, the
upper one is to receive the yarn and act as a guide to the same in its progress to
the cop, spindle, or tube, or whatever it is being wound upon. We make this form
of traveller flat, by preference, as this gives it a greater power of causing tension
upon the yarn with fewer coils of the same around it, which saves time and
labour in piecing. In this case we make either the cop, spindle, or tube act as
a fulcrum, or the outer line of yarn or thread itself do so, in order to give the yarn
or thread, as before mentioned, a greater power over the said traveller.
We also use an additional wharve to the spindle which acts in the manner
of a loose pulley, and greatly facilitates the stopping of the spindle when the
yarn is broken.
The next part of our Invention relates to the formation of cops or bobbins by
the aid of a screw spindle, dish, and winged nut, on what are called winding
machines. To accomplish this object we place a dish or bowl in a vertical position,
and the cop spindle has a rotary motion; the screw spindle is hollow and is fixed
on the rail; the dish or bowl forms a conical nut which carries the guide wire;
this conical nut, dish, or bowl is caused to rotate intermittently by contact with
the yarn when it is wound on the spindle, cop, or tube, which action continues
until the cop is full.
Again, the screw spindle is made hollow to admit of a small wire or other
connection passing through it from the top of the screw to the wharve on the cop
spindle for the purpose of stopping the said spindle automatically when the cop,
bobbin, or tube is full.
The same object may be accomplished by placing a dish or bowl in an inverted
position fixed upon a screw spindle revolving intermittently by contact with the
yarn wound upon the cop, spindle, or tube, in which case the revolving cop,
spindle, or tube moves in a vertical direction away from the inverted cone, dish,
or bowl.
For the purpose of this Invention we use when required a paper tube with a
metallic surface, which makes the tube more durable, enables the user to soak the
cop or tube in water, or to steam it instead, and the yarn spun or wound upon the
said tube works off more freely.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying 3 Sheets of
Drawings.
Figure 1, Sheet 1, is a front elevation of our improved ring throstle for spinning
cotton or any other fibrous material.
Figure 2, Sheet 1, is a plan view of the same.
Letters in the various Figures refer to the same parts.
A is the frame work.
B is the lifting rail placed edgeways up, which is constructed to hold a novel
kind of eyebolt, shewn in Figures 12 and 13, Sheet 2. A heart or cam C working
horizontally by preference in contact with a slide or copping plate D, which is
connected to a chain or flexible band E, by which means a direct pull or push is
given to the parts F₁, F, F, F, working the novel slide bar B, and this, without
the intervention of a first lever as is now used. An adjustable quadrant or lever F₁
in connection with the above named heart C, and slide or copping plate D,
regulates what is commonly called the length of the chase. The object of this
adjustable quadrant F, is for the purpose of varying the length of the chase or
traverse of the slide bar B without changing the heart C, which is done by sliding
the quadrant arm up or down at G.
Again, to the last named adjustable quadrant F₁ is attached an adjustable

page_text: projecting lever H, .by. means of which the motion given by the said slide or
copping plate D is further regulated at the commencement of the cop to be spun,
or when it is working at the cop bottom, in order to give the latter its proper
shape. As the projecting lever H, being attached to the quadrant F, raises the
chain slightly at F, when the quadrant recedes the extremity of lever H, being
suppressed by the adjustable bracket J, the quadrant F, is caused to recede by
the pressure of the weight of the slide bars B, and their attachments, which
weight is partly counter balanced by weights such as F. The eccentric K in the
slide or copping plate D and worked by handle L has for its object the additional
depression of the slide bars B preparatory to the operation of doffing the cops, and
to allow of winding some coils of yarn around the spindle below the finished cop.
When the doffing operation is performed the slide bar 13 is. by means of the same
eccentric K and handle L returned to its proper position for beginning a cop. This
arrangement brings all the first moving parts of the lifting mechanism within
easy access, gives a steadier and more positive motion to the slide bar or rail B,
lifts much easier than the hitherto existing arrangement, also greatly facilitating
the ordinary operation preparatory to what is called doffing.
The second part of our Invention consists in the use of a small spring-ring N,
Figures 1 to 11, Sheet 2, or a portion of one inserted in a suitable circular recess
or groove of a novel eyebolt M. Figüres 1 & 2, Sheet 2, to which spring-ring there
is loosely attached on a pivot a novel form of traveller or small spring-flyer 0.
This novel traveller or spring flyer is so constructed as to swivel upon a pivot P
in a radial direction to and from the cop, spindle, or tube Q, and so come in contact
with the said cop, spindle, or tube in such a manner as to cause the spindle to
act as a fulcrum to the flyer and its attachments, thus giving the yarn a greater
power over it than it otherwise would have when it is working at the apex of
the cop. Opposite or nearly so to the pivot P we make projections on our spring-
ring, one kind of which projections is shewn in Figure 2, Sheet 2, which serves
as a stay to the loose end of the crossbar O, giving the same greater stability.
Again, this said traveller or spring flyer is constructed with a hooked projec-
tion U; this hooked projection may form part of the swivelling crossbar, as shewn
in Figures 1, 2, 5, 6, & 7, Sheet 2; around its upper part the yarn can be coiled
any suitable number of times so as to prevent the tension that is required to wind
a hard cop from affecting and damaging the yarn as it is being delivered from
the rollers. This part of the Invention also facilitates the operation of piecing the
broken yarn or thread. On' the crossbar O there is a projection Z, Figures-1-to-10.
Sheet 2, partly around which-or-around-which the yarn is passed to guide it to
the cop, tube, or spindle. In Figure 6. Sheet 2, the crossbar O is twisted to form
a coil at V, the purpose of which is to increase the diameter of the crossbar at the
point of contact with the cop. The same object is accomplished by other means,
one of which is shewn at V in Figure 7.
2
This traveller can also be constructed in the form of a semiring, with suitable
projections or bends for holding it in a circular recess, and with one or more
projections or bends for guiding the yarn to the cop, spindle, or tube, in combina-
tion with one or more of our projections or bends receiving the coils of yarn, so as
to prevent the tension that is required to wind a hard cop from affecting and
damaging the said yarn as it is being delivered from the rollers. They can also be
constructed of 2 or more rings or parts of rings suitably connected together or in
the form of a fork shaped drag wire combined with our prolonged pivot, or with
one or more of our projections, around which the yarn can be coiled any suitable
number of turns, so as to prevent the tension that is required to wind a hard cop
from affecting and damaging the yarn as it is being delivered from the rollers
through our spring guide wires R, Figures 14 and 15, Sheet 2, which are placed in
grooves on bars S in Figures 14 and 15, Sheet 2. and which may be moved
backwards and forwards individually or simultaneously. In short, these travellers
may be made in various shapes, having the necessary projection or projections for
holding them in their place and for guiding the yarn to the cop, spindle, or tube,

page_text: making the same act as a fulcrumi, some of which shapes we shew by Figures 1
to 10, Sheet 2. We make this form of traveller or spring flyer of flat material by
preference, as this gives it a greater power of causing tension upon the yarn with
fewer coils of the same around it, which saves time and labour in piecing. In this.
case we make either the spindles, cops, or tubes act as a fulcrum, or the outer line
of yarn or thread itself do so in order to give the yarn or thread, as before
mentioned, a greater power over the said traveller or spring flyer.
The plan of Figures 2, 6, 7, & 9, Sheet 2, shew the spring ring clasped, the
manifest advantage of which is that the hooked part of the swivelling crossbar O,
with the yarn which it carries, is sprung against the cop, spindle, or tube, and that
the spring-ring is not so liable to come off spontaneously, but is very easily
removed by hand when required.
Another modification of this Invention consists in an improved form of oblong
flyer used in combination with our spring ring, as shewn at Figure 11, Sheet 2,
We make this form of flyer flat by preference, as this gives it a greater power of
causing tension upon the yarn with fewer coils of the same around it, which saves
time and labour in piecing; in this case we make either the spindle, cop, or tube
act as a fulcrum, or the outer line of yarn or thread itself do so, in order to
give the yarn or thread, as before mentioned, a greater power over the said
traveller.
We also use an additional wharve V, Figure 16, Sheet 3, to the spindle W, which
acts in the manner of a loose pulley and greatly facilitates the stopping of the
spindle when the yarn is broken by pushing the band driving the spindle from the
fast wharve X to the loose wharve V, which revolves around the spindle collar and
does not come in contact with the spindle itself or with the fast wharve. The
advantage of employing this additional wharve to stop the spindle is that it
dispenses with the labour of removing the cop, tube, or bobbin, for the operation
of piecing the broken ends.
We also employ a novel construction of weight book or weight hanger, whereby
one or more small balls placed in the head of the said hook or hanger tend greatly
to lessen the friction betwixt the parts in contact, that is to say, the hook or hanger
and the roller upon which it hangs, thereby giving a more uniform surface speed
between the bottom and top roller, and consequently giving a greater degree of
equality and regularity to the sliver delivered from the rollers.
The next part of our Invention relates to the formation of cops or bobbins by
the aid of a screw spindle, dish, and winged nut, on what are called winding
machines. To accomplish this object we place a dish or bowl A₁, Figure 17,
Sheet 3, in a vertical position, and the cop spindle B, has a rotary motion; the
screw spindle C, is hollow and is fixed on the rail D,. The dish or bowl A, forms
a conical nut which carries a guide wire E₁; this conical nut, dish, or bowl A, is
caused to rotate intermittently by contact with the yarn on the cop, spindle, tube,
or bobbin F; when it is wound on the spindle, cop, or tube, or bobbin F₂, which
action continues until the cop, bobbin, or tube is full, the screw spindle C, is made
hollow to admit of a small wire or other connection passing through it from the
top of the screw at G, to the driving wharve H, on the cop spindle B₁, upon which
there is a projection or projections which remain locked with the driving wharf H,
until the cop, bobbin, or tube is full, when it is lifted out of gear and the cop
spindle B, is caused to cease revolving by the conical nut, dish, or bowl A, coming
in contact with the head of the wire or other connection at G₁; which causes the
hook J, to disconnect the wharve H, from the projection or projections on the cop
spindle B. The operation of doffing the full cops is performed by drawing the
apex of the spindle B, slightly away from the conical nut A₁, as the spring K
which holds the cop spindle B, against the cone gives way; by depressing the
spring L, the cone A is allowed to drop back into its original position. The same
object may be accomplished by placing a dish or bowl in an inverted position fixed
upon a screw spindle and revolving intermittently by contact with the yarn wound
upon the cop, spindle, or tube, in which case the revolving cop, spindle, or tube,

page_text: moves in a vertical direction away from the inverted cone, dish, or bowl; the same
object may be accomplished in various other ways, and the cop spindle driven and
stopped by various other means. For the purpose of this Invention we use when
required a paper tube or cloth tube which is metallized, and makes the tube more
durable, enables the user to steam or otherwise wet the cop, and the yarn spun
or wound upon the said tubes works off more freely.
