Improvements in Machinery or Apparatus for Doubling and Twisting
Yarns or Threads.
We, GEORGE HENRY HOLDEN of Carr Street Manchester in the County of Lancaster
Machinist, and JOHN ASHWORTH of the same place Manager, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to machinery or apparatus for doubling and twisting yarns
or threads and consists in improvements by which we render such machinery or
apparatus more convenient in use than it has hitherto been.
The first part of our invention relates to the draw or drag rollers employed in
the machinery or apparatus to which our invention relates. According to this part
of our invention we mount upon a shaft extending lengthwise of the machine and
constantly rotating a pulley or roller against which the draw or drag roller is at times
pressed. The axle of the draw or drag roller we mount in slots formed in arms
capable of being turned upon a shaft or bar extending lengthwise of the machine
or upon a stud secured to a bracket, secured to a bar or rail extending lengthwise
of the machine. We so mount the said draw or drag roller that when the yarns
or threads to be doubled or twisted are passed around a guide and over the con-
stantly rotating pulley or roller and thence to the spindle, the draw or drag
roller will by the tension of the yarn or thread be drawn towards the constantly
rotating pulley or roller before referred to and thus cause the yarns or threads to
be delivered to the spindle by which they are twisted or doubled.
A further part of our invention relates to arrangements for driving the spindles
of machinery or apparatus for doubling and twisting yarns or threads and consists
in arrangements by which we are enabled to employ one band or belt to "drive"
two spindles upon opposite sides of the machine. In carrying this part of our inven-
tion into effect, we mount upon the driving shaft a pulley around which and around
pulleys upon the spindles we place a band or belt. The pulleys upon the spindles
at times impart rotary motion to the spindles by means of arrangements which
form part of the subject of an application for a patent in our
names dated
September 11th 1888 No. 13106. We pass the band or belt above mentioned over a
guide pulley by which it is guided from or to the driving pulley to, or from the
pulley upon one of the spindles from or to which it passes to, or from the pulley
upon the other spindle from or to which it passes to, or from a guide pulley from
or to which it is conducted to, or from the driving pulley before mentioned.
mount either or each of the guide pulleys above mentioned upon a stud or axle
mounted in or upon a bracket capable of being turned upon a stud or shaft by a weight
or spring which weight or spring serves to maintain the band or belt in any desired
state of tension.

A further part of our invention consists in arrangements by which we are enabled
to "stop" a spindle and the draw or drag roller by which yarn or thread is supplied
to such spindle, when one of the yarns or threads to be twisted or doubled becomes
broken or absent. The yarns or threads to be doubled or twisted we pass through
the eyes of the drop wires or drop levers of any suitable arrangement of detector
mechanism and from such eyes to the draw or drag roller and the palley or roller by
which the yarns or threads are delivered to the spindle. We cause the detector
mechanism to support at such times as yarn or thread is being doubled or twisted, one
end of a lever capable of turning upon a fulcrum. The said lever is jointed to a bar
he upper end of which is at times caused to act upon the draw or drag roller so as to
aise it clear of the roller or pulley by which and the draw or drag roller yarn or thread

delivered to the spindle. The lever above mentioned is also jointed to a rod one end
of which is jointed to a lever provided with a jaw the ends of which act upon the
apparatus by which the spindle is stopped and started." When a yarn or
thread becomes broken or absent a drop wire or drop lever of the detector
mechanism will be allowed to pass into the path of a revolving or oscillating
ratchet, wiper or cam by which the said drop-wire or drop lever will be caused
to liberate the lever above mentioned and thus allow a spring to raise the draw
or drag roller by means of the bars, rods, lever, and jaw before mentioned and so
stop the delivery of yarn or thread to the spindle and by acting upon the parts
by which the spindle is driven" to stop the said spindle. When the broken or
absent yarn or thread has been "pieced" the bars, rods, lever, and jaw before
mentioned are moved against the force of the spring above referred to and caused to
allow the draw or drag roller to move into position for causing yarn or thread to be
delivered to the spindle and place the lever above mentioned in position for being
again supported by the detector mechanism.
A further part of our invention consists in a method of imparting motion to and
stopping the spindles employed in machinery or apparatus for doubling and winding
yarns or threads.
According to this part of our invention we employ a part of the invention which
forms the subject of the application for a patent above referred to and in combination
therewith we employ the spindles known as "Rabbeth spindles." We mount the
pulley or warve by which each spindle is driven so that it is free to be rotated upon
a boss or collar formed upon the tube or part which supports the spindle and we
mount upon the spindle the parts constituting the clutch or clip by which motion is at
times transmitted from the pulley or warve before mentioned to the spindle. In some
cases we provide a bearing in a part hinged or otherwise connected to any suitable part
of the machine which bearing may serve as a bearing for the upper part of the
spindle.
By this part of our invention we are enabled to prevent the "pull" or strain of the
band or strap by which the spindle is "driven," from acting upon such spindle and
we are also enabled to remove the spindle from the tube or part by which it is sup-
ported without disturbing or interfering with the warve or pulley and are thus enabled
to remove the spindle from the tube or part by which it is supported without it being
necessary to remove from the warve or pulley the band or strap by which the spindle
is "driven."

Improvements in Machinery or Apparatus for Doubling and Twisting
Yarns or Threads.
We, GEORGE HENRY HOLDEN of Carr Street, Manchester, in the county of
Lancaster, Machinist, and JOHN ASHWORTH, of the same place Manager, 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 :-
Our invention relates to machinery or apparatus for doubling and twisting yarns or
threads and consists in improvements by which we render such machinery or
apparatus more convenient in use than it has hitherto been.
The first part of our invention relates to the draw or drag rollers employed in the
machinery or apparatus to which our invention relates. According to this part of
our invention we mount upon a shaft extending lengthwise of the machine and con-
stantly rotating, a pulley or roller against which the draw or drag roller is at times
pressed. The axle of the draw or drag roller we mount in slots formed in arins
capable of being turned upon a shaft or bar extending lengthwise of the machine or

page_text: upon a stud secured to a bracket, secured to a bar or rail extending lengthwise of the
machine. We so mount the said draw or drag roller that when the yarns or threads
to be doubled or twisted are passed around a guide and over the constantly rotating
pulley or roller and thence to the spindle the draw or drag roller will by the tension
of the yarn or thread be drawn towards the constantly rotating pulley or roller before
referred to and thus cause the yarns or threads to be delivered to the spindle, by
which they are twisted or doubled.
This part of our invention is illustrated in Fig. 1 of the acconipanying drawings
which figure is an elevation in section of so much of a machine for doubling
and twisting yarns or threads as is requisite to illustrate the greater part of our
invention.
(a) is a constantly revolving shaft fast upon which is mounted a roller (b) against
which the draw or drag roller (c) is at times pressed. The shaft (a) is supported by
brackets (d) secured to a roller beam (e) extending lengthwise of the machine and
carried by end framings (f) one only of which is shown. The axle (c) of the draw
or drag roller (c) we mount in slots (g) formed in arms (9) capable of being turned
upon a shaft or stud (h) carried by the bracket (d).
The yarns or threads to be doubled or twisted passing from the bobbins (A) after
passing over a guide or pulley (), pass beneath the pulley or roller (b) then over the
draw or drag roller (c) and afterwards pass to the flyer () by which after being
twisted together they are wound upon the bobbin (B). The tension of the yarn or
thread to be doubled or twisted and passing around the draw or drag roller (c)
will draw the draw or drag roller (c) towards the constantly rotating pulley or
roller (b) and thus cause the yarns or threads to be delivered to the spindle (4) by
which they are twisted or doubled. An increased tension upon the yarns or threads
will cause the draw or drag roller (c) to be more forcibly pressed against the pulley
or roller (6) and thereby ensure the delivery to the spindle (4) of the yarns or threads
to be twisted or doubled.
In some cases in order to cause the tension of the yarn or thread being twisted or
doubled to press the draw or drag roller (c) against the pulley or roller with a greater
amount of force than can be obtained by the arrangement shown in and described in
reference to Fig. 1, we employ the arrangement shown in the detached view Fig. 2.
According to this arrangement after passing the yarns or threads partially around
the pulley or roller (6) we conduct the yarn or thread around a guide or pulley (1)
and then partially around the draw or drag roller (c) from which the yarns or threads
pass to the spindle (k) to be twisted or doubled.
A further part of our invention relates to arrangements for driving spindles of
machinery or apparatus for doubling and twisting yarns or threads and consists in
arrangements by which we are enabled to employ one band or helt to "drive" two
spindles upon opposite sides of the machine. In carrying this part of our invention
into effect we mount upon the driving shaft a pulley around which and around pulleys
upon the spindles we place a band or belt. The pulleys upon the spindles at times
impart rotary motion to the spindles by means of arrangements which form part of
the subject of an application for a Patent in our names, dated September 11th, 1888,
No. 13106. We pass the band or belt above mentioned, over a guide pulley by
which it is guided from or to the driving pulley to or from the pulley upon one of
the spindles from or to which it passes to or from the pulley upon the other spindle
from or to which it passes to or from a guide pulley from or to which it is conducted
to or from the driving pulley before mentioned. We mount either or each of the
guide pulleys above mentioned upon a stud or axle mounted in or upon a bracket
capable of being turned upon a stud or shaft by a weight or spring which weight-
or spring serves to maintain the band or belt in any desired state of tension.
This part of our invention is also illustrated in Fig. 1, of the accompanying
drawings.
Upon the driving shaft (1) of the twisting or doubling machine we mount a
pulley (m) around which and around pulleys (n) respectively mounted upon
spindles (k) situate at opposite sides of the twisting or doubling machine passes the

page_text: band or belt (0). The pulleys (n) and (n) at times impart rotary motion to the
spindles (k) (k) upon which they are respectively mounted by means of arrange
ments (p) which form part of the subject of our application for the Patent above
referred to. We pass the band or belt (o) over a guide pulley (9) by which it is
guided from or to the driving pulley (m) to or from one pulley (n) from or to which
it passes to or from the other pulley (n) on the spindle (k) from or to which it passes
to or from a guide pulley (r), by which it is conducted to or from the driving
pulley (m). The pulley (g) is mounted and free to be moved upon a shaft or stud (s)
carried by or secured to any convenient or suitable part of the twisting or doubling
machine.
The axle (1) of the pulley (7) we mount so that it is capable of being turned in
bearings formed in a bracket or frame (t) suspended from and capable of being
oscillated upon a stud or bar (u). To the bracket or frame (t) is secured a weight (v)
such weight (v) tending to turn the bracket or frame (t) in the direction indicated by
the arrow (C). The tendency of the weight (v) to turn the bracket or frame (t) in
the direction indicated by the arrow (C) will by means of the pulley ("), maintain
the band or belt (o) in an uniform state of tension. If desired the pulley (9) may
also be carried upon a bracket or frame mounted and operated similarly to the
frame (t). Instead of employing a weight (v) to turn the frame (t) in the direction
indicated by the arrow (C) we may employ a spring arranged in
suitable manner.
any
A further part of our invention consists in arrangements by which we are enabled
to "stop" a spindle and the draw or drag roller by which yarn or thread is supplied
to such spindle, when one of the yarns or threads to be twisted or doubled becomes
broken or absent. The yarns or threads to be doubled or twisted we pass through
the eyes of the drop wires or drop levers of any suitable arrangement of detector
mechanism and from such eyes to the draw or drag roller and the pulley or roller by
which the yarns or threads are delivered to the spindle. We cause the detector
mechanism to support at such times as yarn or thread is being doubled or twisted one
end of a lever capable of turning upon a fulcrum. The said lever is jointed to a bar
the upper end of which is at times caused to act upon the draw or drag roller so as to
raise it clear of the roller or pulley by which and the draw or drag roller, yarn or
thread, is delivered to the spindle. The lever above mentioned is also jointed to a rod
one end of which is jointed to a lever provided with a jaw the ends of which act upon
the apparatus by which the spindle is "stopped" and "started." When a yarn or
thread becomes broken or absent a drop wire or drop lever of the detector mechanism
will be allowed to pass into the path of a revolving or oscillating ratchet, wiper, or
cam, by which the said drop wire or drop lever will be caused to liberate the lever
above mentioned and thus allow a spring to raise the draw or drag roller by means
of the bars, rods, lever, and jaw, before mentioned and so stop the delivery of yarn or
thread to the spindle and by acting upon the parts by which the spindle is "driven"
to stop the said spindle. When the broken or absent yarn or thread has been
"pieced "the bars, rods, lever and jaw before mentioned are moved against the force
of the spring above referred to and caused to allow the draw or drag roller to move
into position for causing yarn or thread to be delivered to the spindle and place the
lever above mentioned in position for being again supported by the detector
mechanism.
This part of our invention is also illustrated by Fig. 1, of the accompanying
drawings.
The yarns or threads (D) to be doubled or twisted after leaving the bobbins (A)
upon which they have been previously wound pass under the bar (w) and through the
eyes (a) of drop wires (a) mounted in a "detector holder" (y) which at times
supports the end (¹) of a lever (=) supported by and capable of being turned upon a
stud or bar (2) carried by the bracket (d) carried by the framing of the machine.
Jointed to the end (2) of the lever () is the lower end of a bar or rod (3) in the
upper end of which is formed a slot (3) which passes over a pin or stud (4), secured
to the bracket (d). The pin or stud (4) serves as a guide upon which the slot (3)
may be slidden and acts as a guide for the upper end of the rod (3).

page_text: Upon the upper end of the rod or bar (3) is formed an incline (3b) which is situate
beneath a pin or stud (6) projecting from the bracket (g).
To the end (2) of the lever (=) is jointed one end of a rod (7), the lower end of
which rod is jointed to the end (8") of a lever (8), mounted and free to turn upon a
stud (9), secured to a bracket (7) carried by the lower spindle rail of the machine.
Upon the end (8b) of the lever (8) is formed a jaw (10) which acts upon the parts to
be hereinafter referred to by means of which the spindle (E) is "stopped" and
" started."
When a yarn or thread becomes broken or absent a drop wire or drop wires (x) of
the detector mechanism will be allowed to pass into the path of the revolving ratchet
or wiper (11) and' thereby cause the ratchet or wiper (11) to turn the part (y)
carrying the detector wires (a) in the direction indicated by the arrow (E).
The end (2) of the lever (2) will by means of the incline (y') keep the fallen
detector wire (a) or detector wires clear of the revolving ratchet or wiper (11). The
end () of the lever () being no longer supported, the spring (12) which is secured
at one end to a bracket (7") secured upon the rod (7) and at the other end to
the roller beam (e), will raise the rod (7) in the direction indicated by the arrow (F)
thus causing the inclined end (3b) of the rod or bar (3) to act against the stud
or pin (6) and thereby raise the draw or drag roller (c) clear of the pulley or
roller () and so stop the delivery of yarn or thread to the spindle (k) the jaw
or fork (10) upon the lever (8) connected to the rod (7) by acting upon the parts
by which the spindle (k) is "driven will stop the spindle (k) at the same time
as the "draw" or drag" roller (c) is lifted.
"
When the broken or absent yarn or thread or yarns or threads has or have
been "pieced the attendant by pressing down the pedal (13) will by means of
the rod (14) turn the lever (8) in the direction indicated by the arrow (G) and
draw down the bar or rod (7) against the force of the spring (12) until the
end (z) of the lever (2) is raised sufficiently to allow the projecting part (y)
upon the detector holder (y) to pass beneath and support the end (2) of the
lever (). The aforesaid drawing down of the rod (7) will have withdrawn the inclined
end (3) of the rod or bar (3) from beneath the pin or stud (6) and thereby
allowed the draw or drag roller (c) to pass into contact with the pulley or
roller (b) thus causing yarn or thread to be delivered to the spindle (*) to be
twisted or doubled. The descent of the rod (7) will by means of the jaw (10)
place certain parts upon which the said jaw (10) acts in position for causing the
spindle () to be driven.
In some cases instead of employing a pedal lever (13) for drawing down the
bar or rod (7) we secure a pedal (15) directly upon the rod (7) as shown at the
right hand portion of Fig. 1. at which placo also the jaw (10) is shown as being
formed upon a bracket (10) secured upon the rod (7) instead of upon a lever
connected to such rod (7).
A further part of our invention consists in a method of imparting motion to
and "stopping" the spindles employed in machinery or apparatus for doubling
and winding yarns or threads.
According to this part of our invention we employ a part of the invention
which forms the subject of the application for a patent above referred to and in
combination therewith we employ the spindles known as "Rabbeth spindles." We
mount the pulley or warve by which each spindle is driven so that it is free to
be rotated upon a boss or collar formed upon the tube or part which supports
the spindle and wo mount upon the spindle the parts constituting the clutch or
clip by which motion is at times transmitted from the pulley or warve before
mentioned to the spindle. In some cases we provide a bearing in a part hinged or
otherwise connected to any suitable part of the machine which bearing may serve
as a bearing for the upper part of the spindle.
This portion of our invention is shown by the right hand portion of Fig. 1. and on
a larger scale in Fig. 3. which is a vertical section in which (n) is the pulley or

page_text: warve by which the spindle (k) is driven. (16) is the tube by means of which the
spindle (k) is supported and in which tube (16) the spindle (k) is free to be
revolved.
Fast within the upper part of the tube (16) is a bush (17). The pulley (#) we
provide with a collar (¹) the outer circumference of which collar is free to revolve
within the bush (17). In some cases instead of placing a bush such as (17) within a
tube (16) we cause the collar (n) to work against the inside of the tube (16). We
mount upon the spindle () the clutch or clip (p) by means of which motion is at
times transmitted from the pulley or warve (n) to the spindle (). The said clutch
or clip (p) is shown in plan in Fig. 4 of the accompanying drawings. The
clutch (p) is similar in construction to that shown and described in the specification
filed in respect of the application for a patent No. 13106 dated September 11th 1888
herein before referred to.
The clutch is provided with jaws or clips (18) which are mounted upon a plate or
disc (19) mounted fast upon the spindle (k).
When the spindle () is to be driven the collar (20) provided with a conical
part (20) is slidden upon the spindle (k) and acts upon the jaws or clips (18) so as
to force them against a circular flange (n) formed on the pulley (n). When the
spindle (k) is to be stopped the conical part (20") of the collar (20) is withdrawn.
from the jaws or clips (18) and so allows a spring (21) to withdraw the jaws or
clips (18) out of contact with the circular flange (n²).
By this part of our invention we are enabled to prevent the "pull" or strain of the
band or strap by which the spindle is "driven" from acting upon such spindle and
we are also enabled to remove the spindle from the tube or part by which it is
supported without disturbing or interfering with the warve or pulley and are thus
enabled to remove the spindle from the tube or part by which it is supported without
it being necessary to remove from the warve or pulley, the band or strap by which
the spindle is "driven."
(22) is a part which is hinged to the bracket (d) or to a rod supported by such
bracket (d) and is provided with a bearing (22) which may when the part (22) is
turned into the position in which it is shown serve as a bearing for the upper
part () of the spindle (k).
Although in the accompanying drawings we have only shown one spindle at each
side of the machine and have above in many cases referred to one spindle only, we
would have it understood that machines constructed according to our invention or
having any part or parts of our invention applied thereto may have any desired
number of spindles at each side.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In a machine for doubling or twisting yarns or threads a constantly rotating
pulley or roller and a draw or drag roller, so arranged and employed in conjunction
with other parts substantially as shown in Fig. 1. or Fig. 2. of the accompanying
drawings that the tension of the yarns or threads being doubled or twisted will cause
the draw or drag roller to be drawn towards the rotating pulley or roller so that the
said yarns or threads will be delivered to the spindle to be doubled or twisted.
2. In a machine for doubling or twisting yarns or threads the hereinbefore
described arrangements by means of which one band or belt may be employed to
drive two spindles upon opposite sides of the machine.
3. In a machine for doubling or twisting yarns or threads the hereinbefore
described arrangement of apparatus for causing a spindle and the draw or drag
roller used in conjunction with such spindle to stop when a yarn or thread or yarns or
threads being supplied to the said spindle becomes or become broken or absent which
arrangement of apparatus consists in a lever such as (2), rod such as (7), spring such
as (12), jaw such as (10), rod or bar such as (3), and pin or stud such as (6) upon

page_text: the bracket supporting the draw or drag roller; all arranged and operating in con-
junction with suitable detector mechanism and other necessary parts substantially as
herein before described in reference to Fig. 1. of the accompanying drawings.
4. In a machine for doubling or twisting yarns or threads the combination of a
"Rabbeth spindle" or spindle supported in a tube and the clip or clutch above
mentioned and arranged and operating substantially as hereinbefore described.
