IMPROVEMENTS IN DOUBLING-WINDING MACHINES
Year: 1884

page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for IMPROVEMENTS IN
DOUBLING-WINDING MACHINES to be as follows:-
This Invention relates to machines for "doubling" and winding two or more
yarns upon a single bobbin and it consists essentially in a machine having an
automatic stop motion brought into operation by the breaking of a yarn and in
which all the working parts are improved in such manner as to ensure a rapidity
and certainty of action not hitherto attainable in these machines.
The distinctive features of the machine whereby a single attendant is enabled
to control a greater number of heads at one time and in a superior manner are the
following:
1 The automatic and immediate stoppage of the winding on bobbin or spool
when a yarn breaks by a simple mechanical arrangement not liable to get out of
order.
2nd The yarns are perfectly guided so as to always ensure the exact degree of
tension required without causing any strains liable to injure or break them this
object being more especially attained by the application of a rod or cross bar
between the feed roller and the yarn guides.
3rd In the arrangement and combination with the mechanism of an oscillating
plate carrying the yarn guides and connected with the self acting stop motion; said
plate in combination with a stationary adjustable rod or cross bar producing the
forward movement of the yarn guides on the stop motion coming into action whereby
they are rendered more easy of access, and the piecing up can be more quickly and
conveniently effected.
4th In a novel arrangement of counterbalance suspended by a chain from the arm
of the oscillating plate, and connected to a lever acting in combination with a
hinged bobbin holder as hereinafter specified.
5th In the general construction arrangement and combination of the different
parts. These advantages are obtained by the construction of machine illustrated in

page_text: the accompanying drawings which represent as an example a machine head for
winding six yarns although this number may be varied without in any way
departing from the Invention.
Figure 1 represents a face view of a machine head for six yarns. Figure 2 a,
corresponding end view and figure 3 a section looking towards the stop motion
lever. Figure 4 shows a diagram of the position of the parts when the machine is
working and figure 5 a similar view showing the position of the parts when the stop
motion comes into operation, on the breaking of the yarn.
The same letters of reference indicate like parts in all the figures.
As the invention relates to the construction of the different parts of the machine
with a view to obtain the results above indicated, I will proceed to describe each
part in succession, distinguishing in each the features of novelty. The yarn
supplied from bobbins a passes through the fixed guide b by which it is conducted
to a roller c having a roughened surface to produce the draft. To prevent dust
impeding the rotation of the roller which should turn very freely, it is made hollow
so as to enclose and protect its journals. The axis of roller c is a spindle d screwed
at one end in a cheek plate e carried upon the right hand arın of the swinging
plate hereinafter described. The spindle d passes freely through the opposite
cheek plate e and projects sufficiently to enable the attendant to grasp it (see
figure 1). The cheeks ee¹ are braced together by a tie rod g, under which the
yarns pass, so that the point at which the yarns leave roller c, the point at which
they touch rod g, and the eye of yarn guide shall be in a straight line. The
plate fis pivoted at i to swing freely on the breaking of a yarn as hereinafter
described, but so as to always hang vertically in the normal operation of the
machine.
The spindle upon which oscillate the yarn guides and their counterbalances h¹
is mounted in arms f' f2 of plate fin a suitable position with regard to the axis i
so that on the breaking of a yarn the axis of the yarn guides and consequently the
guides themselves swing towards the attendant, whereby the yarns may be readily
pieced up.
At the upper curved end of the arm f' a weight j is suspended by a chain, said
weight being also connected at its bottom end to the stop motion lever k by a
chain whose tension is regulated by a nut j.
To the lower end of the arm f¹ is jointed the rod by which a leather tongue is
inserted between the bobbin or spool m and the drum n (by which it is driven by
frictional contact) for the purpose of arresting the spool. o is a shaft having blades
(see figure 2) which is capable of adjustment more or less closely to the lower edge
of plate f for a purpose hereinafter described.
The bobbin or spool m is mounted in a frame p hinged to the lower rail g of the
frame so as to allow of the bobbin or spool rising as its diameter increases." ¹ is a
yarn guide rod carried upon the lever . p is a stud on one side of frame p which
is adjustable in a slot in said frame and fixed by a nut. In the normal working of
the machine, the vertical side of this stud bears against the face of the weighted
lever which is curved to an are of a circle described from the pivot of frame p as
a centre. Contact of the two parts is ensured by regulating the tension of the
lower chain of weight j by means of nut j¹. The object of so curving the lever / is
to prevent the constantly increasing size of the bobbin producing any effect upon
the upper mechanism. The weighted lever k also carries the rod k¹ beneath w hich
the doubled yarn passes, said rod being so arranged with reference to the pivot of
lever that on the stop motion coming into action, it will rise together with the
mechanism so as to allow room for the attendant to introduce her hand.
When the bobbin or spool has attained the desired size, the stud p* which rises
with the frame p disengages the lever and rests upon the incline k² thereby
throwing the parts out of gear automatically. To facilitate this operation, the
lever is weighted at its free end where it is attached to the lower chain of
weight. The lever is pivoted on arms r bolted to the lower cross rails 8 of the
frame. Between each pair of arms are pivoted levers t carrying the leather

page_text: tongue t¹ which is to be inserted between the bobbin and its friction drum for
stopping the motion; said arms r also carry the guides u for the reciprocating
thread guide by which the yarn is laid smoothly upon the bobbin (see figure 1°) the
yarn being led through a small guide u³ attached to a rod u' receiving to and fro
motion from a cam u³ in the groove of which runs a pin on the carrier to which
the end of the reciprocating rod u is fixed..
:
The lower end of the connecting rod l being jointed to the bell crank levert to
which the leather tongue t¹ is attached the latter is thrust forward between the
friction drum and the bobbin or spool and thus arrests the motion of the latter.
The action of the machine is as follows:-The yarns to be united pass under
roller c and rod g; through the eyes of the yarn guides h and thence under rod k¹
to the bobbin the tension of each yarn being sufficient to hold up the weight
attached to its guide h. A cross wire v fixed by its downwardly bent ends in holes
in a rail v serves to hold down those guides h which are not in use and which act
as a support for those which are in use the former being below and the latter
above it.
When the machine is in operation, the lower chain of weight j is in tension but
has no strain on it so as to be in readiness to actuate the stop motion immediately
a yarn breaks; the weight and rod are thus in equilibrium during the normal
working of the machine. When a yarn breaks, the counter weight h¹ of its guide h
descends into the path of the revolving blades o which strike it against the plate f
thereby oscillating the latter and causing the leather tongue to be advanced
between the bobbin and the friction drum thus arresting the bobbin. The
weight at same time drops slightly and slackens the lower chain, so that
immediately the bobbin holder is raised on its pivot p by the attendant lifting the
projection x, the lever k falls bringing its incline beneath the stud p³ and thereby
holding the bobbin raised; the lever in falling also puts the lower chain ; in
tension.
The combined effect of raising the axis of the yarn guides by the oscillation of
plate fand their arrest at the same level by the adjustable bar y is to throw their
eyes well forward within reach of the attendant so as to render easy the piecing up
of the yarns.
The oscillation of the plate falso causes the yarn guides h to bear against the
fixed bar y whilst their centre is displaced and occupies the position seen in
figure 5, thus raising their balance weights / sufficiently to move them out of the
path of blades o.
To restart the machine it is simply necessary to pull the upper roller c forward
thus drawing back the leather tongue, putting chain j again in tension and raising
lever k, thus releasing the stud by which the bobbin holder is supported and
allowing the bobbin to again resume contact with its friction drum, and recommence
the winding.

53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN DOUBLING-WINDING MACHINES," 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 machines for "doubling" and winding two or more
yarns upon a single bobbin and it consists essentially in a machine having an
automatic stop motion brought into operation instantaneously by the breaking of
a yarn and in which all the working parts are improved in such manner as to
ensure a rapidity and certainty of action not hitherto attainable in those machines.
The distinctive features of the machine whereby a single attendant is enabled to
control a greater number of heads at one time and in a superior manner are the
following:
1 The automatic and immediate stoppage of the winding-on bobbin or spool
when a yarn breaks, obtained by a simple mechanical arrangement not liable to get
out of order.
2nd The yarns are perfectly guided so as to always ensure the exact degree of
tension required without causing any strain liable to injure or break them, this
object being more especially attained by the application of a rod or cross bar
between the feed roller and the yarn guides.
3rd In the arrangement and combination with the mechanism of an oscillating
plate carrying the yarn guides.and connected with the self acting stop motion;
said plate in combination with a stationary adjustable rod or cross bar producing the
forward movement of the yarn, guides on the stop motion coming into action
whereby they are rendered more easy of access, and the piecing up can be more
quickly and conveniently effected.
4th In a novel arrangement of counterbalance suspended by a chain from the
arm of the oscillating plate and connected to a lever acting in combination with
a hinged bobbin holder as hereinafter specified.
5th In the general construction arrangement & combination of the different parts.
These advantages are obtained by the construction of machine illustrated in the
accompanying drawings which represent as an example a machine head for winding
six yarns although this number may be varied without in any way departing from
the Invention.
Figure 1 represents a face view of a machine head for six yarns. Figure 2 a
corresponding end view and figure 3 a section looking towards the stop motion
lever. Figure 4 shows a diagram of the position of the parts when the machine is
working normally and figure 5 a similar view showing the position of the parts
when the stop motion comes into operation, on the breaking of the yarn.
The same letters of reference indicate like parts in all the figures.
As the invention relates to the construction of the different parts of the machine
with a view to obtain the results above indicated I will proceed to describe each
part in succession, distinguishing in each the features of novelty. The yarn supplied
from bobbins a passes through the fixed guide b by which it is conducted to a
roller c having a roughened surface to produce the draft. To prevent dust
impeding the rotation of the roller which should turn very freely, it is made hollow
so as to enclose and protect its journals. The axis of roller c is a spindle & screwed
at one end in a cheek plate é carried upon the right hand arm of the swinging

page_text: plate hereinafter described. The spindle d passes freely through the opposite
cheek plate e¹ and projects sufficiently to enable the attendant to grasp it (see
figure 1). The cheeks e e¹ are braced together by a tie rod g, against which the
yarns pass, tangentially so that the point at which the yarns leave roller C, the
point at which they touch rod g, and the eye of yarn guide h shall be in a straight
line. The plate is pivoted at i to swing freely on the breaking of a yarn as
hereinafter described, but so as to always hang vertically in the normal operation
of the machine.
The spindle upon which oscillate the yarn guides h and their counterbalances h¹
is mounted in the arms f¹ f2 of plate fin a suitable position with regard to the
axis so that on the breaking of a yarn the axis of the yarn guides and
consequently the guides themselves swing towards the attendant, whereby the
yarns may be readily pieced up.
At the upper curved end of the arın f¹ a weight j is suspended by a chain, said
weight being also connected at its bottom end to the stop motion lever k by a
chain whose tension is regulated by a nut j¹.
To the lower end of the arm f¹ is jointed the rod by which a leather tongue is
inserted between the bobbin or spool m and the drum n (by which it is driven by
frictional contact) for the purpose of arresting the spool. o is a shaft having blades
which is capable of adjustment (see figure 2) more or less closely to the lower edge
of plate for a purpose hereinafter described.
The bobbin or spool m is mounted in a frame p hinged to the lower rail g of the
frame so as to allow of the bobbin or spool rising as its diameter increases. k¹ is a
yarn guide rod carried upon the lever . p is a stud on one side of frame p
which is adjustable in a slot in said frame and fixed by a nut. In the normal
working of the machine, the vertical side of this stud bears against the face
of the weighted lever / which is curved to an arc of a circle described from the
pivot of frame p as a centre. Contact of the two parts is ensured by regulating
the tension of the lower chain of weight j by means of nut j¹. The object of so
curving the lever k is to prevent the constantly increasing size of the bobbin
producing any effect upon the upper mechanism. The weighted lever also carries
the rod beneath which the doubled yarn passes, said rod being so arranged with
reference to the pivot of lever / that on the stop motion coming into action, it will
rise together with the mechanism so as to allow room for the attendant to
introduce her hand.
When the bobbin or spool has attained the desired size, the stud p³ which rises
with the frame p disengages the lever and rests upon the incline thereby
throwing the parts out of gear automatically. To facilitate this operation, the
lever is weighted at its free end ³ where it is attached to the lower chain of
weight. The lever is pivoted on arms r bolted to the lower cross rails s of the
frame. Between each pair of arms are pivoted bell crank levers t carrying the
leather tongue which is to be inserted between the bobbin and its friction
drum for stopping the motion; said arms r also carry the guides u for the
reciprocating thread guide by which the yarn is laid smoothly upon the bobbin
(see figure 1) the yarn being led through a small guide u² soldered or otherwise
attached to a rod u receiving to and fro motion from a cam u³ in the groove of
which runs a pin on the carrier to which the end of the reciprocating rod u¹ is
fixed.
'
The lower end of the connecting rod being jointed to the bell crank levert to
which the leather tongue t¹ is attached the latter is thrust forward between the
friction drum and the .bobbin or spool and thus arrests the motion of the latter.
The action of the machine is as follows:-The yarns to be united pass under roller c
and rod g; through the eyes of the yarn guides h and thence under rod to the
bobbin the tension of each yarn being sufficient to hold up the weight ¹ attached to
its guide h. A cross wire fixed by its downwardly bent ends in holes in a rail v¹
serves to hold down those guides which are not in use and which acts as a
support for those which are in use the former being below and the latter above it.

When the machine is in operation, the lower chain of weight j is in tension but
has no strain on it so as to be in readiness to actuate the stop motion immediately
. a yarn breaks; the weight j and rod l are thus in equilibrium during the normal
working of the machine. When a yarn breaks, the counter weight h¹ of its
guide descends into the path of the revolving blades o which strike it against the
plate thereby oscillating the latter and causing the leather tongue to be advanced
between the bobbin and the friction drum thus arresting the bobbin. The weight j
at same time drops slightly and slackens the lower chain, so that immediately the
bobbin holder is raised on its pivot p by the attendant lifting the projection x, the
lever k falls bringing its incline beneath the stud p² and thereby holding the bobbin
raised; the lever in falling also puts the lower chain j in tension.
The combined effect of raising the axis of the yarn guides by the oscillation of
plate fand their arrest at the same level by the adjustable bar y is to throw their
eyes well forward within reach of the attendant so as to render easy the piecing up
of the yarns.
Th oscillation of the plate f also causes the yarn guides h to bear against the
fixed bar y whilst their centre is displaced and occupies the position seen in
figure 5, thus raising their balance weights h¹ sufficiently to move them out of the
path of blades o.
To restart the machine it is simply necessary to pull the upper roller c forward
thus drawing back the leather tongue, putting chain j again in tension and raising
lever k, thus releasing the stud by which the bobbin holder is supported and
allowing the bobbin to again resume contact with its friction drum, and
recommence the winding.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1 In a machine for doubling and winding yarns the employment of the rod g
in combination with the upper roller c so that the threads pass tangentially against
this rod g in a straight line to the guides has described and represented in the
drawings annexed.

described.
