Improvements in Self Acting Spinning Mules.
I, JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been communicated
to me from abroad from La Société A. Grandjeans & Company of St. Louplet (Nord)
in the Republic of France Manufacturers to ho as follows:-
This Invention relates to self acting spinning machinery of the class referred to in
the application for Letters Patent made by James Yate Johnson on the 1st of June
1887 No. 7922 and comprises an improved combination of mechanism hereinafter
described which is employed for regulating the action of the machine during the first
period of the formation or huilding up of the cap or hobbin. With this object we
employ an apparatus which operates on the same general principles as that described
in the said former Specification but which is modified as regards the construction and
arrangement of certain parts in order to suit the different conditions under which it is
required to operate as hereinafter explained.
According to the invention described in the said former Specification the quadrant
nut is connected to the chain of the winding on cylinder and the quadrant screw is
rotated in such a manner as to regulate the position of the nut and consequently the
action of the winding mechanism in accordance with the varying diameters on which
the thread has to be wound.
In carrying out the present invention I ascertain by calculation with the aid of
diagrams if necessary the length of the screw and tho exact positions of the nut
corresponding to the varying diameters on which the thread is wound in building
up the base of the cop, the winding action in coiling the thread on the bare part
of the spindle being also provided for. The counter faller on arriving at the end
of its stroke should be at such a distance from the faller as to leave sufficient
thread between these two parts for winding on the baro spindle at the momont
when the faller rises. This distance must gradually decrease as the operation
proceeds and the spindle is covered. To obviate risk of breaking the thread when
the carriage has run in it is necessary for the thread to form a small snare to
compensate for irregularities in the diameters of the tubes or in the position of
the top of the spindles and also in the speed at which the carriage runs in. The
latter causes the pitch of the helix formed by the thread to be modified according
as the faller rises more or less rapidly. These irregularities are provided for in
the construction of the apparatus according to our invention. An arm or lever on
the carriago which acts upon a lever on the headstock connected with the nosing
motion is connected to a pinion gearing with a pinion on the axis of the counter
faller and the movements of the levers are so combined as to retain between the faller
and counterfaller exactly the quantity of thread required for the coils above the
base of the cop the said levers being made of peculiar curved forms regulated
according to the effect to be produced.
When the carriage runs in the arm on the carriage acts on the lever on the
headstock which acts through a combination of levers and mechanism similar to that
described in the former Specification hereinbefore referred to on ordinary toothed or
preferably ratchet toothed wheels transmitting motion to the screw on the quadrant.
The pitch chains driving the ratchet toothed wheels are acted on by tension rollers
and as the copping rail descends on the plates it acts through a bell crank lever on a
horizontal rack which rotates a sprocket wheel driving another sprocket wheel on the
shaft of a toothed wheel gearing with a vertical rack connected to a triangular frame with
slotted sides similar to the triangular frame described in the said former Specification.
When a draw has been wound and the thread has made the required number of

page_text: turns on the base tube and spindle above the cop base the counter faller resumes the
position for running out which is lower than the position at the end of the winding on
and the lever or arm on the carriage is consequently higher. To disconnect this arm
from the lever on the headstock a bell crank laver oporated by an arm on the beam
lover receiving motion from the faller shaft for example is caused to push the
lover on the headstock to one side so that it is clear of the arm on the carriage.
When the carriage runs in too quickly the faller rises very rapidly, less thread is
allowed on the bare spindle and the snare is made long; when the carriage runs
in slowly the fuller rises less rapidly and the snare is short or absent or the thread
may even be broken. When the improved regulator is employed the counter fuller
is raised higher when the carriage runs in too quickly so as to tend to leave out
more thread but the arm on the carriage is lowered being operated by the toothed
gearing and consequently acts later on the lever on the headstock. On the other
hand when the carringe runs in slowly the counterfaller descends lower but the lover
on the carriage is raised higher and nets sooner on the lever on the headstock.
When the base of the cop is formed the arm carrying the antifriction bowl on the
end of the lever arm on the carriage is turned back out of the way and the lever
connected with the nosing motion for the second period of the formation of the cop
is brought into action being similarly provided with a pivoted arm. The said arms
may be fixed in position by set screws and the hell crank lever connected with the
copping rail may also be thrown out of action by taking out one of the pins.
The mechanism regulating the formation of the second period is independent of the
mechanism connected with the first period and either apparatus may be employed
separately or the two may be combined on the same support.
The arms or levers on the carriage being provided with jointed arms carrying the
bowls acting on the lovers on the head stock the vertical lever controlling the toothed
or ratchet wheels of the nosing motion may be made in one piece instead of being
jointed as in the arrangement described in the said former Specification. The
tension rollers hereinbefore referred to aeting on the pitch chains are employed to
compensate for the lateral displacement of the sprocket wheels transmitting motion
to the screw in connection with the mechanism for regulating the winding of the
second period as well as in that for the first period. The form and inclination of
the levers on the headstock is carefully regulated so as to enable the arms on the
carriago to cause the said levers to operate the regulating mechanism in the manner
required and the ends of the levers are curved upwards to facilitate their engagement
with the lovers on the carringe.

Improvements in Self Acting Spinning Mules.
1, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do berchy declare the nature of this Invention which has been communicated to
mo from Abroad by La Société A. Grandjeans & U of St. Souplet (Nord) in the Republic
of France, Manufacturers 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 improvements in self acting spinning mules or machinery
of the class referred to in the Specification describing an invention for which Lettors
Patent were granted to James Yate Johnson dated 1st June 1887 No. 7922 and com-
prises an improved combination of mechanism hereinafter described which is employed
for regulating the action of the machine with regard to the nosing motion during the
first period of the formation or building up of the cops or hobbins. With this object
an apparatus is employed which operates on the same general principles as that
described in the said former specification but which is modified as regards the

page_text: construction and arrangement of certain parts in order to suit the different conditions
under which it is required to operate as hereinafter explained.
nut
According to the invention described in the said former specification the quadrant
connected to the chain of the winding on cylinder and the quadrant screw is
rotated in such a manner as to regulate the position of the nut and consequently the
action of the winding mechanisin in accordance with the varying diameters on which
the thread has to be wound.
In carrying out the present invention the length of the screw and the exact positions
of the nut corresponding to the varying diameters on which the thread is wound in
building up the base of the cop or bobbin is ascertained by calculation with the aid of
diagrams if necessary the winding action in coiling the thread on the bare part of
the tube or spindle above the layers being also provided for.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheets of drawings the same letters of reference indicating
corresponding parts in all the corresponding figures.
The mechanism next hereinafter described and illustrated in Figures 1, 2, 3 and 4
of the accompanying drawing comprises several parts which taken separately are
similar to those which are employed in the improved nosing motion or mechanism
described in the specification No. 7922 of 1887 as being employed in the second
period of the formation of the cops.
Figure 1 of the accompanying drawings represents in side elevation partly in
section so much of the mechanism of a self acting spinning mule as is necessary to
explain the present invention. Figure 2 shows the inechanisin in front elevation like-
wise partly in section and Figures 3 and 4 are viows similar to Figures 1 and 2 but
illustrating a modified arrangement of the mechanism controlling the nosing motion
for the second period as hereinafter explained.
The lever C Figures 1 and 2 being operated by toothed wheels or pinions g and h
as hereinafter explained comes in contact when the carriage runs in after each draw
with a lever D' fixed on a shaft E' on the headstock. A lever F' fast on this shaft E¹
causes a triangular frame G' H' 1' to oscillate on a centre O¹ and rock a lover L'
jointed at M. On the back shaft N is keyed a sprocket or chain wheel P' which
drives a similar wheel S₁ attached to a chain wheel T¹ driving a chain wheel U¹ and
ratchet toothed wheel Z¹ carried on the extremity of an arm V' suspended at O".
This arm V¹ is connected to the lever L' by a link ✗'. A spring placed on the
axis 0" (fig. 2.) maintains the lever L'in contact with the bowl on the end of a
rod K¹ connected to the triangle G H l'and limited in its movement in one direction
by a pin bearing against its support. A ratchet toothed wheel Y¹ communicates
through an endless chain with the lower part of the quadrant the screw of which is
operated by bevel gear in the usual way.
The position of the parts indicated in the drawing corresponds with the running in
of the carriage. When the lever D¹ is raised the lever L' is rocked and the ratchet
toothed wheel Z driven from the back shaft N is put in gear with the ratchet toothed
wheel which rotates to the extent determined by the relative positions of the
levers CD for the time being.
The tension of the endless chains driven by the sprocket wheels P¹ and T¹ is
regulated by tension pulleys 10' and 11' (Figure 1). In proportion as the copping
rail descends on the copping plates a bell crank lever 2 operated by a pin 1 on the
inner extremity of the rail displaces a rack 3. This rack imparts rotary motion to a
shaft 8 which by means of chain gear drives a pinion 5 gearing with a rack on
the lower end of a rod 6' and causes this rod to move upwards.
The side I of the triangle G' H' 1' is vertical and the side G₁ is slanting or
inclined. The rod 6' being caused to rise vertically and the action of the spring on
the axis O" pushing the rod K' back against its support the side 11 also ascends
vertically and the inclined side G' gradually pulls in the rod K" which raises the
lever D¹ to an extent corresponding to the angle which the side G¹ makes with the
horizontal side H¹ of the adjustable triangle GH¹¹. When the arm C¹acts upon

page_text: and lifts the lover D' the rod 6 remains at the same elevation for the time and is
consequently unchanged when the bowl on the arm ("leaves the lever D'. The rod 6¹
does not rise and cause the inclined side of the jointed or adjustable triangle to
raise the lever L nntil the ratchet of the rail causes the copping plates to advance or
lower the rail at the end of each draw.
Directly the winding on of the draw is concluded and the thread enrried up to the
tip of the spindle the counter fallor resumes its position for the running out of the
carriage. This position is lower than that for the end of the winding on and conse-
quently the position of the lever or arm is higher. Theso two levers (and D'
consequently now require to be disengaged and in order to disconnect the arm ("
from the lever the extremity of the beam lever i (Figure 2) receiving motion from
the faller shaft is provided with an arm & operating a bell crank lever constructed
with a forked arino which is caused to push the lever D to one side or in the direction
of the length of the shait El so as to clear the armi C. The lever D' is connected to
the shaft by means of suitable feathers and key ways or grooves which admit of
this lateral movement of the said lever.
The second period of the formation of a cop for example is the period in which
that part of the cop marked fk to pm in Figure X is formed the first period
being that employed in buibling up the part a ƒ ƒ³ 1 m n. The present invention
concerns this part chiefly and the method of ascertaining the correct proportions
and combinations of the parts for regulating the nosing motion by means of which
it is formed or built up are described by my foreign correspondents as follows.
To enable the operation during this period to be more readily understood this part
of the cop is illustrated separately in a diagram (Figure Y) drawn to a larger scalo.
Let aand a f¹ be each divided into five equal parts and let the diameters of
the layers be as follows :-

A diagram may be drawn indicating the position of the drum of the quadrant and
of the chain connecting the quadrant to the drum. The result is the same in the case
of cops as that above indicated with regard to the quantities to which the nut is to
be raised. In the case of bobbins it is necessary to make this diagram.
With this object the base of the bobbin being divided into five parts (1, 2, 3, 4, 5
fig. 5) in the same way as the base of a cop the number of revolutions of the spindle
required for winding on each of the 6 draws indicated by the division lines in the
base is ascertained and the differences between the number of revolutions are found
by the same operation as hereinbefore described with reference to cops.
The base or first period of the winding of the bobbin is represented by the diagram
in figure 5 of the accompanying drawings and figure 6 is a diagram shewing the
position of the quadrant at the end of the running in of the carriage.
This position when once practically fixed in the machine is never altered but
always remains the same at the end of the winding of every draw or at the end of
every running in of the carriage. In this diagram, B representing the drum and a
the quadrant nut there is a length a b of chain between the nut and the point where
the chain is in contact with the circumference of the drum. The number of revolu-
tions of the spindle required for winding on the first draw is greater than for any of
the succeeding draws so that a bis the maximum length, the point a being the lowest
position of the nut on the quadrant.
With bobbins the number of revolutions of the spindles for winding on the last
draw in the base or for the end of the first period being the smallest the length alb
represents the minimum length that is to say for the last draw in the base the point a¹
represents the highest position of the nut as according to the construction this
point a must not be situated beyond the intersection of a lino drawn at right angles
to a a' and at a tangent with the drum. Consequently the difference between a b
and a represents the difference in the number of revolutions (A) ascertained as
hereinbefore explained which is required for winding on the first and the last draws
in the base of the bobbin. Taking D as the diameter of the drum the developement
of the circumference is D. As the spindles are driven by the drum the relation
existing between their speeds is -the spindles describing a revolutions to 1 revo-
lution of the drum that is to say for a D development of chain the spindles describe n
revolutions and for A revolutions of the spindles the length of chain required
π D X A
= Z.
n
ab being a known quantity the length abis equal to a b-Z and the lengths
which may be represented by a bar and a 6 for the intermediate
positions between the first and last draw in the 1st period and corresponding to the
draws represented by the division lines in the diagram of the base are readily found.
By means of the diagram the positions of these lines a" " et. can be determined

page_text: and give the olovation of the nut required to obtain the number of revolutions in the
winding that is required for each of the four intermediate draws in question. This
method does not apply so conveniently in the case of cops; the distance between a
and a corresponding to the extreme positions of the nut being relatively small
compared to what is required for a hobbin the points & on the drum are liable to be
confused. The elevation of the nut is therefore made proportional to the differences
between the numbers of revolutions in the draws as hereinbefore described.
b
In the regulator mechanism arranged according to this invention the arm or
lever C described with reference to Figures 1 and 2 of the accompanying drawings
acts upon the lever D' on the headstock for a certain period the duration of which is
regulated according to the extent to which the nut is to be raised. For example the
lever C Figure 1 raises the lover D' to a certain extent when the winding is taking
place on the part a a' of the cop but must coase to raise the said lover D when the
part is reached.

Assuming that the screw of the quadrant is of uniform pitch the speed of the back
shaft (N Figure 1) being the same for each draw and the speed of the chain

In order to arrive at this rosult (neglecting the quantity in the turns made on
the baro spindle above the layers which diminishes at oach draw and is hereinafter
considerod) let it be assumed that the lovor C (Figure 1) controlled by the counter-
faller A meets the lever D₁ at the same level at each draw then according to the
above mentioned conditions it is necessary that each of the points in the lever DI
corresponding to a bede and in the cop (Figure Y) must be in this horizontal
line when the part a b c d e f of the cop is being built up in order that the lifting

page_text: is the winding is proceeding on the parts indicated by the lines a ab b¹c c¹ &c.
Referring to the diagram Figure Z let the line L T represent the level or
horizontal line in which the bowl on the lever arm C₁ travels. In order to
put the two ratchet toothed wheels Z' and ' (Figure 1) in gear with one another
at the required periods during the formation of the cop bottom the lever D' must be
raised 5 millimetres at the point 6. Let the dotted line lt (Figure 2) represent a
straight line drawn at a distance of 5 millimetres from the line IT and passing
through the point 6 corresponding to f. Let E' (fig. Z) represent the centre of
oscillation of this lever D. From the point 6 on the line 1, set off the
lengths 79-105-134-5-185-6 and 270 m/m obtained according to the last
calculation which enables us to find the position of the points 6, 5, 4, 3, 2, 1
(Figure 2) corresponding to the parts a, f, è, d, e, b, a in the cop (Figure Y). The
distances between these points and the centre E¹ are 92-158-178-210-259
and 340 respectively. At the commencement of the rise the point 1 must be on the
line LT.

Taking El as the centre strike arcs of circles passing through the points 1, 2, 3, 4, 5
and 6 and intersecting at 11, 21, 3, 4, 5, and 6', horizontal lines drawn at the
vertical distances from the line L T as found by the above calculation (2.81,
463 etc). A line drawn through the points 1', 21, 31, 4, 5', 6' represents the
mean form or profile of the arm of the lever D¹.
m
In practice the bowl on the lever C₁ is caused to travel on the dotted line L' T'
situated at a distance of 2 above the line LT on account of the play or clearance
which must be allowed for between the teeth of the wheels Y and Z when out of
gear and in order that the ratchet teeth may come in gear again towards the end
of the first period. This has a tendency to put the wheels too much in gear for
a certain period but the lever L' M¹ being jointed at M' deflects in such a manner
that the action of the lever C₁ is not affected. The arm of the lever D' terminates
with an upward curve as indicated in the drawings so that in case the spinner has
neglected to properly adjust the quadrant nut at starting the lever C¹ cannot pass
over the lever D¹.
The small quantity of yarn hereinbefore referred to being wound on the bare spindle
above the regular winding modifies the extent to which the lever D' requires to be
raised.
The counter faller A on arriving at the end of its stroke should be at such a distance
from the faller B as to leave sufficient thread between these two parts for winding on
the bare spindle at the moment when the faller B rises. This distance must gradually
decrease as the operation proceeds and the spindle is covered the distance a¹ S
figure X being gradually reduced to f¹S when the second period commences. The
length of thread between the layers and the tip of the spindle thus becomes shorter
after each draw. To obviate risk of breaking the thread when the carriage approaches
the bean it is necessary in order to compensate for irregularities in the diameters of
the tubes or in the position of the tops of the spindles and also in the speed at which
the carriage runs in to allow the yarn or thread to form a small snarl that is to say

page_text: there must be a certain amount of slack allowed. According to the differenze in the
speed of the carriage the pitch of the helix formed by the thread on the baro tube or
spindle is modified the faller rising more or less rapidly and this difference in speed
results from variations in the speed of the motor or in the tension of the cord of tho
counter scroll and the friction in the winding action. These irrogularities are com-
pensated by the netion of the regulator according to this Invention.
The said small snarl or slack should be the same or equal at tho conclusion of the
winding on of each draw. The spinner must pay attention to this point if there be
no regulator to automatically control the position of the nut and when a regulator is
employed attention to this point also enables him to ascertain whether the regulator
is working properly or not. Figure 5 represents the relative positions of the fallers
and spindles when the carriage las run out and just before the winding on (backing
off). Figure 6 represents the positions of these parts when the draw has been wound
on the earringe having run in. The faller B concludes the winding on of the first
draw at a¹ and the winding on of the last draw in the first period terminates at ƒ³.
Assuming that the counter faller always comes up to the same level at the end of the
travel say to the point T Figure 6 for example whether the faller is concluding the
windling on at a' or at it is evident that by the action of the faller the length of
thread allowed for the upper part of the spindles is merely reduced by the distance
in a straight line from a to f¹ whereas it is requisite that
be reduced to an extent
equal to the development of the number of turns of thread that are wound upon the
tube or on the spindle from a¹ to 7' a length which is greater than the straight
lino at is consequently necessary for the point T being the position of the
counter faller at the time when the thread is being wound on the upper part of the
spindle to be lower at each draw so as to retain between the faller and counter faller
only so much thread (fig. 6) as is required for winding on the upper part of the
spindle at the end of each draw. It is consequently necessary for the lover 1 to
follow the point T. This lover having been already raised as hereinhertore explained
the point in the lever Cª corresponding to the point T on the counter taller is likewise
raised by the winding on the upper part of the spindle by elmuging the direction of
motion of the lever (by the aid of gearing figures 1 and 2 the pinion being
fixed on the axis of the counter faller A and the pinion being fixed on the axis of
the lever C. In order to maintain the correct relationship or connection between the
lovers C and D' determined as aforesaid the lever D' must be raised to the extent
required by the differences in the amounts of thread successively wound on the upper
part of the spindle plus the extent to which is required to rise in order that the
lever may not net upon D' when the winding on has reached the termination of the
first period or formation of the base of the cop. It is evident that the solution herein-
before given for a cop of stated dimensions is applicable to any other form of cops or
bobbins as far as the formation of the base or first period is concerned.
The speed of the carriage in running in is liable to vary from canses hereinbefore
referred to. When the carriage runs in too quickly the faller rises very rapidly less
thread is allowed on the upper part of the spindle and the slack or snarl is con-
sequently greater. When the carriage runs in more gently the faller rises less rapidly
and the snarl is short or absent or the thread may even he strained and broken. The
regulator is brought into action in consequence of these differences. When the
carriage runs in too quickly the counter faller is raised higher and thero is con-
sequently a tendency to leave an excess of thread in the slack or snarl but the arm (1
is proportionately lowered from the same cause at the same time by the action of the
gearing or toothed wheels and hand its operation is thereby retarded and it raises
the lever arm D later. When the carriage runs in slowly on the contrary the counter
faller tends to be lowered excessively which corresponds with too little thread in the
snarl or slack but the lever Q' is raised from the same cause and its operation is
thereby advanced so that it nets sooner on the lever D' and thus compensates for the
irregularity. When the speed is regular the parts revert to their normal operation as
hereinbefore described,

page_text: The winding of the lower part or base of the cop being terminated the jointed arm
carrying the antifriction bowl and forming part of the lever arm is turned aside by
the Spinner and the regulator or nosing motion for the second period as described in
the Specification No. 7922 of 1887 is brought into action by shifting the bowl on the
lever C (figures 3 and 4) as hereinafter described in such a manner as to cause it to
pass under the lever D when the carriage runs in.
The extremities of the lever arm C controlling the nosing motion for the second
period and of the arm controlling the first period are formel with forks p and pl
respectively (figures 1 and 3) in which are jointed the extremities of the studs or
axes a figure 3 and a figure 1 of the bowls which act on the corresponding
levers D and D on the beadstock. The Spinner simply requires to turn the axis of
the bowl through an angle of about 90 degrees and fix it in the required position by
the aid of set screws e figure 3 or el figure 1 in order to put the nosing motion of
either period out of action and bring the other into operation.
The base of the cop being completed the corresponding nosing motion ceases to act
and that of the second period being required in winding cops only is useless in winding
bobbins.
The rail continues to descend on the copping plates during the second period of
winding on bobbins and would still continue to raise the rod 6 (figure 1). In order
to prevent this the spinner must disconnect the bell crank lever Q from the link g, by
drawing out the pin by which these parts are connected. This pin must be replaced
when a fresh series of bobbins is to be commenced.
The same base or support carries the two regulating mechanisms controlling the two
nosing notions there being one regulating mechanism on the right and one on the left
of the said support.
The mechanism may be supplied in either of three forms namely
1. The regulator or nosing motion for the first period, separate, to be employed in
winding either cops or bobbins.
2. The regulator or nosing motion for the second period, separate, for cops only.
3. The two regulators or nosing motions combined on one support.
The lovers and D employed for controlling the nosing motion for the second
period as described in the Specification No. 7922 of 1887 are modified by applying to
the lever D, figure 3, employed in the second period, the principles of construction
hereinbefore described with reference to the lever D¹ figure 1. Figures 3 and 4 show
the levers C and D with the fork p on the end of the lever or arm (carrying the
bowl which acts upon the lever D. This arrangement for putting the mechanism out
of action enables the upper arın L M of the vertical lever LM L" figure 3 to be
made in one rigid piece instead of being jointed as indicated in figure 4 and as
indicated in the arrangement described in the Specification No. 7922 of 1887.
In order to build up a cop with the aid of these two regulators of the nosing
motion the spinner first places the axis a' b fig. 1 of the bowl on the lever arm
(1st period) perpendicular to the axis or centre line c' d' of this arin and the axis ab of
the bowl on the arm C 2nd period is placed in line with the axis or centre line cd of
this arm. By these means the regulator of the nosing motion for the first period is
caused to operate whilst that for the second period is thrown out of action. The
base of the cop being completed the spinner reverses the positions of the parts, the
regulator for the first period (and which had already ceased to act) is rendered
inoperative and the regulator of the second period comes into play.
In winding bobbins the spinner commences by inserting the pin connecting the
paris Q and 9. The axis a' b¹ of the bowl is placed perpendicularly to the axis or
centre line cd of the lever C¹ and the regulator of the first period is thus caused to
act.
When the base is completed the regulator ceases to act but the spinner must
remove the pin r and put the axis a' b¹ in line with the axis or centre line c'd.
The regulator for the second period is constructed with a tension pulley 10 figure 3
which counteracts the tendency of the pitch chain to draw the wheel Z out of gear
with the wheel Y at the moment when the lever LM is pushed by the rod K the
pulley 10' figure 1, performs a similar function during the first period.

page_text: Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For regulating the first period of the winding of cops and bobbins in self acting
spinning mules the employment of a quadrant regulator or nosing motion operating
on the principles set forth in the Specification No. 7922 of 1887, the said regulator or
nosing motion being combined and operating in the manner and for the purpose
substantially as hereinbofore described and illustrated in figures 1 and 2 of the
accompanying drawings.
2. For regulating the second period of the winding of cops and bobbins the
modified arrangement of the nosing motion or regulator substantially as hereinhofore
described and illustrated in figures 3 and 4 of the accompanying drawings.
3. The several combinations and arrangements of mechanism constituting the
improved quadrant regulators or nosing motions for self acting spinning mules sub-
stantially as hereinhofore described with reference to the accompanying drawings.
