Improvements in the Spindles of Ring-spinning Machines and Ring-
doubling Machines, and in Appliances to be used with such
Spindles.
I, FERDINAND ROSSKOTHEN, of Avenue Parade, Accrington, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention consists in improvements in the spindles of ring-spinning machines
and ring-doubling machines for spinning and doubling and in appliances to be
used with such spindles.
The yarn or thread or twist produced in a ring-spinning machine or ring-
doubling machine is generally unwound in the mill in which such machine is
employed from the ring-bobbins on to which it is wound as it is spun or doubled
or twisted and wound either on reels to be formed into hanks or bundles or on
to large bobbins to be used in the formation of warps or in the formation of
doubled yarn or thread and when the ring-bobbins are to be emptied in the mill
in which they are filled they are generally made of wood or compressed paper or
other material of great diameter and weight. For some time past it has been a
growing practice not to unwind the yarns or threads or twist from ring-bobbins
in the mills in which such ring-bobbins are filled, but to send the yarn or thread
or twist away in the form of full ring-bobbins and for this purpose the ordinary
ring-bobbins are objectionable because among other reasons as they have to be
sent away with the yarn or thread or twist and to be returned empty, their great
weight and bulk increase the cost of freight and therefore it has been found
preferable to spin or double or twist the yarn or thread or twist produced in
ring-spinning machines and ring-doubling machines on to very light and thin
paper or other tubes. As the blades of ordinary ring-spinning or ring-doubling
spindles are for most purposes too thin to have the paper or other tubes placed
directly upon them it is usual to place a plug or tip on the blade of a spindle
on which a paper or other tube is to be placed so that such tip or plug may
form a support for the paper or other tube. The tips or plugs used hitherto on
ring-spindles are objectionable whether they are made to be placed only on the
tips of the spindles or to cover considerable parts of the blades or
the whole blades of the spindles on. which they are placed for the
reason that they often stick fast in the paper or other tubes and so get lost
in the doffing of the spindles and because the yarn, thread or twist spun, doubled
or twisted on to paper or other tubes on the spindles tends to pass into the spaces,
nicks or gaps between the tips or plugs and the sleeves of the spindles so that
not only is waste caused but the yarn accumulating in such spaces, gaps or nicks
causes the spindles to be out of balance and causes the paper or other tubes
mounted thereon to run untrue." The tips or plugs hitherto used on ring-
spindles may be prevented from sticking in the paper or other tubes placed upon

page_text: them and being pulled off the spindles therewith, by being driven very firmly on
the blades of the spindles or by being glued or otherwise fastened firmly thereon
but this is attended with the further objection that spindles with plugs or tips
of the kind hitherto used firmly fastened thereon can not be used with ordinary
ring-bobbins.
The objects of my invention are principally to enable spindles to be provided
with detachable plugs so as to be equally suitable for enabling yarn or thread
or twist to be spun or doubled or twisted either on to thin paper or other tubes
or on to ordinary ring-bobbins and to provide plugs which while being detach-
able from the spindles on which they may be placed shall while in use be firmly
secured thereon so as not to be liable to be disturbed by the working of the
spindles or the doffing of yarn or thread or twist therefrom and shall bear so
closely against or so cover the sleeves of the spindles on which they are placed
that there may be no spaces, gaps or nicks into which yarn or thread or twist
spun or doubled or twisted on to paper or other tubes placed upon such plugs
may pass or catch and so to prevent waste and interference with the proper running
of the spindles and paper or other tubes on to which yarn or thread or twist is
to be spun, doubled or twisted from occurring.
According to my invention I provide each spindle to which my invention is
to be applied with a screw-thread or screw-threads or incomplete screw-thread
or incomplete screw-threads or a groove or grooves or notch or notches or pin or pins
or a spring or other catch or spring or other catches or projection or projections or
hook or hooks or any other suitable means by which a plug to be placed upon such
spindle or a bush, cap or nut capable of bearing or being made to bear upon and
hold such plug shall be held firmly on such spindle while being capable of being
readily removed therefrom as may be requisite from time to time when an
ordinary ring-bobbin is to be placed thereon. The screw-thread or screw-threads
or incomplete screw-thread or incomplete screw-threads or pin or pins or groove
or grooves or notch or notches or catch or catches or projection or projections
or hook or hooks upon the spindle may be formed or provided or secured upon, or
upon a bush secured upon the sleeve which secures the wharve of the spindle to
the blade thereof or upon the tip of the blade of the spindle or on the said
blade near the sleeve or at any other part of such blade. The plugs provided in
accordance with my invention are preferably made of light wood, but may be
made of compressed paper or other suitable materials and when to be directly
secured to the spindle to which they are applied are provided with screw-threads
or partial screw-threads or pins or spring or other catches or grooves or notches
or other means by which they may be made to engage with the screw-threads
or partial screw-threads or grooves or pins or other means provided to receive or
act or correspond with them upon the spindles on which such plugs are to be
placed. The screw-threads or partial screw-threads or pins or spring or other
catches or grooves or notches or other means by which plugs made according to
my invention are to be secured to the spindles on which they are to be placed
are preferably formed or provided in or upon metal hushes which may either be
formed wholly or in part by stamping or pressure or be formed by any other

spindles tend to keep such plugs firmly secured thereon.
Plugs provided in accordance with my invention may be made of any size
which may be desirable in accordance with the size of the paper or other tubes
which it may from time to time be desirable to place thereon and may be so
made that plugs of different sizes may be used at different times with one spindle
and are so made that when they are placed and secured in position upon the
spindles to which they are to be applied they shall be in such close contact
with or so cover the sleeves upon such spindles that there may be no spaces, gaps
or nicks between them and the sleeves of the spindles to offer a lodgment or
place or means of engagement for yarn or thread spun, doubled or twisted on to
the paper or other tubes placed on such plugs and according to my invention
plugs which are to be employed with paper or other tubes of large diameter are
although secured in the manner herein before described made to cover or extend
over the sleeves of the spindles like ordinary ring-bobbins. In order to enable
spindles to which my invention is applied to be more conveniently used with
ordinary ring-bobbins whenever it may be desirable to so use them, I provide
according to my invention caps or covers capable of being secured by means of.
and covering or protecting, the screw-threads or partial screw-threads or grooves
or pins or spring or other catches or projections or hooks or other means of
attaching plugs or bushes, caps or nuts to such spindles and preferably form
such caps or covers so that when they are in use the spindles shall present the
appearance of and be capable of being used in precisely the same way as ring-
spinning spindles or ring-doubling spindles of ordinary construction. The said
caps or covers may be formed by stamping or pressure or other suitable means and
either wholly of metal or paper or wood or other suitable material or of any
combination of materials.

Improvements in the Spindles of Ring-spinning Machines and Ring-
doubling Machines, and in Appliances to be used with such
Spindles.
I, FERDINAND ROSSKOTHEN, of Avenue Parade, Accrington, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:―
My invention consists in improvements in the spindles of ring-spinning machines
and ring-doubling machines for spinning and doubling and in appliances to be
used with such spindles.
The yarn or thread or twist produced in a ring-spinning machine or ring-
doubling machine is generally unwound in the mill in which such machine is
employed from the ring-bobbins on to which it is wound as it is spun or doubled
or twisted and wound either on reels to be formed into hanks or bundles or on
to large bobbins to be used in the formation of warps or in the formation of
doubled yarn or thread and when the ring-bobbins are to be emptied in the mill
in which they are filled they are generally made of wood or compressed paper or
other material of great diameter and weight. For some time past it has been a

page_text: growing practice not to unwind the yarns or threads or twist from ring-bobbins
in the mills in which such ring-bobbins are filled, but to send the yarn or thread
or twist away in the form of full ring-bobbins and for this purpose the ordinary
ring-bobbins are objectionable because among other reasons as they have to be
sent away with the yarn or thread or twist and to be returned empty, their great
weight and bulk increase the cost of freight and therefore it has been found
preferable to spin or double or twist the yarn or thread or twist produced in
ring-spinning machines and ring-doubling machines on to very light and thin
paper or other tubes. As the steel blades of ordinary ring-spinning or ring-doubling
spindles are for most purposes too thin to have the paper or other tubes placed
directly upon them it is usual to place a plug or tip on the blade of a spindle
on which a paper or other tube is to be placed so that such tip or plug may
form a support for the paper or other tube. The tips or plugs used hitherto on
ring-spindles are objectionable whether they are made to be placed only on the
tips of the spindles or to cover considerable parts of the blades
the whole blades of the spindles on which they are placed for the
reason that they often stick fast in the paper or other tubes and so get lost
in the doffing of the spindles and because the yarn, thread or twist spun, doubled
or twisted on to paper or other tubes on the spindles tends to pass into the spaces,
nicks or gaps between the tips or plugs and the sleeves of the spindles so that
not only is waste caused but the yarn accumulating in such spaces, gaps or nicks
causes the spindles to be out of balance and causes the paper or other tubes
mounted thereon to run "untrue." The tips or plugs hitherto used on ring-
spindles may be prevented from sticking in the paper or other tubes placed upon
them and being pulled off the spindles therewith by being driven very firmly on
the blades of the spindles or by being glued or otherwise fastened firmly thereon
but this is attended with the further objection that spindles with plugs or tips
of the kind hitherto used firmly fastened thereon can not be used with ordinary
ring-bobbins.

The objects of my invention are principally to enable spindles to be provided

may pass or catch and so to prevent waste and interference with the proper running
of the spindles and paper or other tubes on to which yarn or thread or twist is
to be spun, doubled or twisted from occurring.
According to my invention, I provide each spindle to which my invention is
to be applied with a screw-thread or screw-threads or incomplete screw-thread
or incomplete screw-threads or a groove or grooves or notch or notches or pin or pins
or a spring or other catch or spring or other catches or projection or projections or
hook or hooks or any other suitable means by which a plug to be placed upon such
spindle or a bush, cap or nut capable of bearing or being made to bear upon and
hold such plug shall be held firmly on such spindle while being capable of being

or incomplete screw-thread or incomplete screw-threads or pin or pins or groove
or grooves or notch or notches or catch or catches or projection or projections
or hook or hooks upon the spindle may be formed or provided or secured upon, or
upon a bush secured upon, the sleeve which secures the wharve of the spindle to
the blade thereof or upon the tip of the blade of the spindle or on the said
blade near the sleeve or at any other part of such blade. The plugs provided in

page_text: accordance with my invention are preferably made of light wood, but may be
made of compressed paper or other suitable materials and when to be directly
secured to the spindle to which they are applied are provided with screw-threads
or partial screw-threads or pins or spring or other catches or grooves or notches
or other means by which they may be made to engage with the screw-threads
or partial screw-threads or grooves or pins or other means provided to receive or
act or correspond with them upon the spindles on which such plugs are to be
placed. The screw-threads or partial screw-threads or pins or spring or other
catches or grooves or notches or other means by which plugs made according to
my invention are to be secured to the spindles on which they are to be placed
are preferably formed or provided in or upon metal bushes which may either be
formed wholly or in part by stamping or pressure or be formed by any other
suitable means and may be secured
the
any suitable
requisite positions in such plugs. When partial screw-threads are to
be employed they may in some cases be made in the form of mere
projections and in some cases there may be employed pins or projections which
may be turned into and out of correspondence with grooves or notches for the
plugs to be placed and secured upon or removed from the spindles to which they
are applied. When bushes, caps or nuts are to be employed to bear upon and
hold the plugs upon the spindles such bushes, caps or nuts may be formed of
any suitable material or combination of materials and in any suitable manner.
The screw-threads or partial screw-threads or other means provided according to my
invention to enable plugs to be secured upon spindles are preferably so arranged

in
manner in
Plugs provided in accordance with my invention may be made of any size
which may be desirable in accordance with the size of the paper or other tubes
which it may from time to time be desirable to place thereon and may be so
made that plugs of different sizes may be used at different times with one spindle
and are so made that when they are placed and secured in position upon the
spindles to which they are to be applied they shall be in such close contact
with or so cover the sleeves upon such spindles that there may be no spaces, gaps
or nicks between them and the sleeves of the spindles to offer a lodgment or
place or means of engagement for yarn or thread spun, doubled or twisted on to
the paper or other tubes placed on such plugs and according to my invention
plugs which are to be employed with paper or other tubes of large diameter are
although secured in the manner hereinbefore described made to cover or extend
over the sleeves of the spindles like ordinary ring-bobbins. In order to enable
spindles to which my invention is applied to be more conveniently used with
ordinary ring-bobbins whenever it may be desirable to so use them, I provide
according to my invention caps or covers capable of being secured by means of.
and covering or protecting, the screw-threads or partial screw-threads or grooves
or pins or spring or other catches or projections or hooks or other means of
sttaching plugs or bushes, caps or nuts to such spindles and preferably form
such caps or covers so that when they are in use the spindles shall present the
appearance of and be capable of being used in precisely the same way as ring-
spinning spindles or ring-doubling spindles of ordinary construction. The said
caps or covers may be formed by stamping or pressure or other suitable means and
either wholly of metal or paper or wood or other suitable material or of any
combination of materials.
In the accompanying drawings, throughout which the same letters of reference
are employed to indicate corresponding parts several forms of my invention are
illustrated.
Fig. 1 is a vertical section in part a side elevation showing one form of plug
made according to my invention and the manner in which it may be applied to
a spindle.
In the form of my invention which is illustrated by Fig. 1, the upper part of

page_text: the sleeve (a) by which the spindle-wharve (b) is fastened to the spindle-blade (c)
is somewhat reduced in diameter and a screw (d) is cut into it, and the plug (e)
is firmly connected at its lower end with a metal bush (f) which has in its interior
a screw-thread (e¹) corresponding with the screw-thread () on the spindle-sleeve (a).
The plug (e) can thus be screwed on the spindle or taken away as may be requisite
from time to time and the screw (d) enables the said plug to be so tightly
fastened to the spindle that there remains practically no slit in which the yarn
could be caught.
Fig. 2 is a vertical section in part a side elevation showing another form of
plug made according to my invention and the manner in which it may be applied
to a spindle.
In the form of my invention which is illustrated by Fig. 2 the spindle is
formed with a screw-thread (d) in the same way as the spindle illustrated in
Fig. 1 but the plug (e) is of a kind which may be used in cases in which as
when spinning very soft yarn or when using very large rings it is desirable to
spin or double or twist on to tubes of a large diameter. The plug illustrated in
Fig. 2 is of such a large diameter that its lower part passes over the sleeve (a)
of the spindle like an ordinary spinning bobbin and a bush (f) formed with an
internal screw-thread to correspond with the screw-thread (d) upon the spindle-
sleeve is secured in the interior of the plug (e). The plug (e) illustrated in Fig. 2
and the plug illustrated in Fig. 1 are capable of being employed interchangeably
with the same spindles.
When the spindles illustrated in Figs. 1 and 2 are to be used in spinning,
doubling or twisting on to ordinary bobbins, the plugs are taken away and on
the sleeve of each spindle a little cap (9) illustrated in Fig. 3, which is a vertical
section in part a side elevation, is placed so as to protect the screw (d) and
prevent the yarn from being caught in it. When the cap (9) is placed upon a
spindle, the spindle has the same appearance as an ordinary spindle and ordinary
bobbins can be used on it, the same spindle thus being capable of being used for
thin and thick paper tubes and for ordinary bobbins as well. It is not absolutely
necessary to use the cap (9) when either of the spindles illustrated in Figs. 1
and 2 is being used with ordinary bobbins, but it is preferable to do so.
Fig. 4 is a vertical section in part a side elevation showing a part of a plug and
spindle and illustrating another form of plug made according to my invention
and the manner in which it may be applied to a spindle.
In the form of my invention which is illustrated in Fig. 4 the spindle-blade (c)
is formed with a screw-thread (d) at the top and the plug (e) is pressed down by
a small loose cap (f) which is screwed on the top of the spindle.
Fig. 5 is a vertical section in part a side elevation showing part of a plug and
spindle and illustrating another form of plug made according to my invention and
the manner in which it may be applied to a spindle and have a paper or other
tube placed upon it.
In the form of my invention which is illustrated in Fig. 5 the plug (e) is
furnished at the top with a little bush (f) formed internally with a screw-thread
to correspond with a screw-thread (d) formed upon the top of the spindle-blade (c)
like the screw-thread illustrated in Fig. 4.
Fig. 6 is a side elevation in part a vertical section illustrating the way in
which either of the spindles illustrated in Figs. 4 and 5 may be provided with a
little metal cap (g) to cover the top of the spindle-blade (c) and protect the screw-
thread () thereon while such spindle is being used with ordinary bobbins.
Fig. 7 which is in part a vertical section and in part a side elevation illustrating
another form of my invention, shows a spindle in which the screw-thread (d) by
means of which a plug is to be attached to the spindle is cut into the bottom of
the blade (c) of the spindle and not into the sleeve (a) as in the forms of spindle
illustrated in Figs. 1, 2 and 3.
Fig. 8 which is in part a vertical section and in part a side elevation illus-
trating another form of my invention shows a plug which instead of being

page_text: provided with complete screw-threads is provided with two projections (f¹)
stamped out and bent over so as to be capable of engaging with the screw-
threads (d) upon the spindle to which such plug is to be applied.
Fig. 9 which is in part a vertical section and in part a side elevation illustrating
another form of my invention illustrates a plug (e) provided with a bush (f)
formed with a screw-thread by being placed around a screw-thread formed upon a
steel or other suitable mandrel of suitable size and subjected to great external
pressure so as to be so pressed into such screw-thread that it is impressed with
a screw-thread which as is illustrated by Fig. 9 may be made to engage with the
screw-thread (d) upon the spindle to which such plug (e) is to be applied.
Fig. 10 which is in part a vertical section and in part a side elevation illus-
trating another form of my invention shows a plug (e) formed with a screw-
thread either in a previous operation or in being screwed upon the spindle to
which it is to be applied.
Fig. 11 which is a vertical section in part a side elevation and Fig. 12 which
is a plan illustrate another form of my invention and show a spindle with a
groove (h) formed around the sleeve (a) and two notches (¹) therein and Fig. 11
shows how the plug (e) used with such spindle is provided with a collar or
bush (f) in which projections (f) of a size and shape corresponding with the
notches (¹) are formed by portions being cut partly round and driven inwards.
By the plug (e) being placed upon the spindle and turned so that the projec-
tions (f) are brought opposite to the notches (¹), the projections (f¹) may be
passed through such notches (¹) and then by the plug (e) being turned into
another position it may be secured upon the spindle and by the said movements
being performed in a reverse order the plug (e) may be easily removed from the
spindle whenever its removal may be desirable.
Fig. 13 which is a side elevation illustrating another form of my invention
illustrates a spindle provided with a projecting pin (i) and a plug (e) provided with
a ring (f) of metal in which is formed a notch (2) shaped so that it may act as
what is ordinarily termed a bayonet-lock and enable the plug (e) to be placed
on the spindle and secured in position by being turned thereon in one direction
or to be released therefrom by being turned thereon in the opposite direction.
It is preferable that the notch (f) shall as is indicated be so shaped or inclined that
the turning of the plug (e) to secure it upon the spindle will cause the plug to be
pressed downwards upon the spindle so as to be made to bear tightly upon the
upper end of the sleeve (a) of the spindle.
Fig. 14 which is a vertical section in part a side elevation of a part of a plug
and spindle and Fig. 15 which is a side elevation of a part of a plug illustrate
another form of my invention in which a screw-thread (d) is formed in an annular
groove () in the upper part of the sleeve (a) and the plug (e) is furnished with
a screw-thread (e) corresponding with the screw-thread (d) of the spindle-
sleeve (a). The plug (e) can thus be screwed on the spindle or taken away as may
be requisite from time to time and the screw (d) enables the said plug to be so
tightly fastened to the spindle that there remains practically no slit in which the
yarn could be caught.
Fig. 16 is a side elevation in part a vertical section illustrating one method of
applying a protective cap to the spindle of which part is illustrated in Fig. 14
When the spindle illustrated in Fig. 14 is to be used in spinning, doubling or
twisting onto ordinary bobbins the plug (e) is taken away and a cap (g) is screwed
into the sleeve (a) so as to protect the screw (d) formed therein and the spindle
has then the same appearance as an ordinary spindle and ordinary bobbins can be
used on it, and thus the same spindle can be used for thick and thin paper tubes
and for ordinary bobbins as well. It is not absolutely necessary to use the cap (g)
when the spindle illustrated in Fig. 14 is being used with ordinary bobbins, but
it is preferable to do so.
Fig. 17 which is a side elevation illustrates a spindle provided with a ring (f)
of metal in which is formed a notch (2) shaped so that it may act as what is

page_text: ordinarily termed a bayonet-lock so that when the plug (c) which is shown in
partial side elevation separately in Fig. 18 and is furnished with a projecting
pin () is placed upon the spindle it may be secured in position by being turned
thereon in one direction and be released therefrom by being turned
thereon in the opposite direction. It is preferable that the notch (2) shall as is
indicated in the drawing be so shaped or inclined that the turning of the plug (e)
to secure it upon the spindle will cause the plug to be pressed downwards upon
the spindle so that its shoulder (e³) shall be pressed tightly upon the upper end
of the bush (f).
Fig. 19 is a side elevation in part a vertical section illustrating another form of
my invention in which the spindle is formed with a screw-thread (d) in the
interior of its upper extremity and the plug (e) is pressed down by a small loose
cap (f) which is screwed on the top of the spindle.
Fig. 20 is a side elevation of a protective cap and a side elevation in part a
vertical section illustrating one method of applying a protective cap (9) to the
spindle of which part is illustrated in Fig. 19 to cover the top of the spindle-
blade (c) and protect the screw-threads therein while such spindle is being used
with ordinary bobbins.
In the use of screws or other holding devices which act by the plugs being
turned in one direction to be fastened and in the other to be released the screw-
threads or other holding devices are preferably arranged so that the direction of
the turning by which the plugs are secured upon spindles shall be contrary to
the directions in which the spindles are revolved so that the revolution of the
spindles while at work will tend to keep the plugs applied thereto in position
upon such spindles, thus when screw-threads are used, I prefer to make twist
spindles with left-hand screws and weft spindles with right-hand screws.
Fig. 21 which is a vertical section in part a side elevation illustrating another
form of my invention shows the manner in which in any cases in which it
may be desirable as in cases in which my invention is to be applied
to existing spindles in which it may not be convenient to form screw-threads
bushes () with screw-threads (d) upon their exterior surfaces may be provided
upon the blades of the spindles instead of screw-threads being cut into such
spindles. In the arrangement illustrated in Fig. 21 a small ring or bush (j) pre-
ferably made of metal is driven by force or put whilst hot or fastened in any other
suitable manner on the blade (c) of the spindle. Into this ring a thread or
groove is cut or a pin is fastened in the same manner as into the sleeves of the
spindles illustrated in Figs. 1, 2, 3, 8, 9, 10, 11, 12, and 13 and thus plugs (e)
similar to those illustrated in Figs. 1, 2, 3, 8, 9, 10, 11, 12, and 13 may be applied
to the spindle illustrated in Fig. 21, and when ordinary wood bobbins are to be
used on the spindle illustrated in Fig. 21 a cap (g) similar to that illustrated
in Fig. 3 may be applied to the bush (j).
The methods in which spring catches may be employed to secure plugs to
spindles in accordance with my invention may be readily understood and carried
into effect without being illustrated by drawings and without further description.
In Fig. 5 a thin paper tube (k) is shown as applied to the plug shown in such
figure.
The plugs employed according to my invention which is applicable to spindles
of all kinds used in ring-spinning machines and ring-doubling machines are
preferably made of light wood but other materials such for instance as compressed
paper or light metal may be used.
My invention enables spindles to be provided with detachable plugs so as to be
equally suitable for enabling yarn or thread or twist to be spun or doubled or
twisted either on to thin paper or other tubes or on to ordinary ring-bobbins and
also provides plugs which while being detachable from the spindles on which they
may be placed shall while in use be firmly secured thereon so as not to be liable
to be disturbed by the working of the spindles or the doffing of yarn or thread
or twist therefrom and shall bear so closely against or so cover the sleeves of the

page_text: spindles on which they are placed that there shall be no spaces, gaps or nicks iuto
which yarn or thread or twist spun or doubled or twisted on to paper or other
tubes placed upon such plugs may pass or catch and thus the plugs made according
to my invention prevent waste and interference with the proper running of the
spindles and paper or other tubes on to which yarn or thread or twist is to be
spun, doubled or twisted from occurring.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
-
1. The combination with a ring-spindle for use in spinning, doubling or twist-
ing yarn or thread of a screw-thread either on the sleeve or on the blade of such
spindle or a groove in the sleeve or a pin in the sleeve or other equivalent device
whereby a detachable plug may be secured to the spindle, arranged and employed
substantially as and for the purposes herein before described.
2. For use in machinery for spinning or doubling or twisting yarn or thread
by means of ring-spindles detachable plugs which are fastened to the spindles by
screw-threads or by grooves and hooks or bayonet-joints or other equivalent
devices substantially as and for the purposes hereinbefore described.
3. For use in machinery for spinning or doubling or twisting yarn or thread
