Year: 1885

page_text: I JOHN DODD of Oldham in the County of Lancaster Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN THE MACHINERY OR
APPARATUS KNOWN AS RING SPINNING MACHINES AND RING DOUBLING MACHINES
AND USED FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS
to be as follows :—
My invention relates to the machinery or apparatus known as ring spinning
machines and ring doubling machines and used for spinning and doubling cotton
and other fibrous materials.
The first part of my invention refers to the copping or lifting motion used in
the machinery or apparatus known as ring spinning machines and ring doubling
machines and consists in arrangements by means of which I am enabled to readily
lower the copping or ring rail into position for allowing the cops or bobbins to be
doffed from the spindles.
In carrying the first part of my invention into effect I mount the heart or cam
employed for raising and lowering the copping or ring rail so that such heart or
cam can be slidden longitudinally upon the shaft upon which it is mounted and
I impart rotary motion to such heart or cam by means of a clutch box. The teeth
or projections of one part of the said clutch box are formed upon the said heart
or cam and the teeth or projections of the other part of the said clutch box are
formed upon the side of the wheel by which the heart or cam is rotated. To the
lever by means of which the copping or ring rail is raised and lowered I secure a
stud upon which I mount a bowl upon which the heart or cam above mentioned
acts to raise and lower the copping or ring rail and I provide the said bowl with &
conical part so that when the heart or cam above mentioned is slidden longi-
tudinally upon the shaft by which it is carried the said heart or cam will be passed
on to the smaller part of the conical part of the bowl before referred to and allow
the lever upon which such bowl is mounted to ascend and so lower the copping or
ring rail into a position convenient for allowing the cops or bobbins to be doffed
By such lowering of the copping or ring rail the yarn or thread is enabled to be
wound upon the spindles below the cops when required.
When it is desired to
doff the cops I so turn a lever provided with an arin and mounted upon a stud
carried by the frame of the machine as to bring the outer end of the arm above
mentioned into the path of an incline formed upon the heart or cam above referred
to and I so cause the said heart or cam to be slidden longitudinally against the
force of a spring on the shaft by which the heart or cam is carried until the teeth
or projections of the part of the clutch-box formed upon the heart or cam will be

page_text: drawn out of gear with the teeth or projections of the other part of the clutch
box by means of which the heart or cam is rotated so that the motion of the
heart or cam is arrested. I cause the heart or cam to be stopped when in such
position that the copping or ring rail is at the bottom of its normal "lift" at
which time the sliding of the heart or cam above mentioned will have caused such
heart or cam to arrive upon the smaller part of the conical part of the bowl above
referred to and thereby allow the copping or ring rail to descend so that the yarn
or thread may be wound upon the spindles below the bases of the cops-After the
yarn or thread has been wound upon the spindles below the bases of the cops
the machine is stopped and the cops may be doffed from the spindles-Before the
formation of a fresh set of cops is commenced the copping or lifting motion must
be "wound" back to the proper position for commencing the building of a fresh
set of cops-To commence spinning or forming a fresh set of cops the machine is
put in motion and the lever above referred to is turned so as to remove the arm
connected there with clear of the incline upon the heart or cam before mentioned
and thus allow the heart or cam to be slidden longitudinally by means of the
spring above mentioned so that the teeth or projections of the part of the clutch
box which is upon the heart or cam will pass into gear with the teeth or projections
of the part of the clutch box by which the said heart or cam is rotated so that the
heart or cam will be rotated-In some cases I employ a lever operated by the
attendant to assist the spring above mentioned in moving one part of the clutch
box into gear with the other part of such clutch box. The heart or cam above
mentioned having been slidden longitudinally as above described will have caused
the circumference of the heart or cam to act on the larger part of the bowl
previously mentioned and cause the copping or ring rail to be raised into position
for commencing the building of the cops.
A further part of my invention consists in arrangements by which I am enabled
to govern the winding of the yarn or thread upon the spindles of the machinery
or apparatus known as ring spinning and ring doubling machines and used for
spinning and doubling cotton and other fibrous materials so that the layers of
yarn or thread are wound upon the cops or bobbins in alternately varying
spirals and thus build a firm cop-In accomplishing the object of this part of my
invention I employ a double throw heart or cam having one throw of the heart or
cam of greater lift than the other throw of such heart or cam-The above
mentioned heart or cam acting in conjunction with the bowl for raising and
lowering the copping or ring rail and the circumference of the heart or cam being
formed as above described will cause the layers of yarn or thread to be wound upon
the cop in alternately varying spirals.
A further part of my invention relates to the machinery or apparatus known as
ring spinning machines, and ring doubling machines and used for spinning and
doubling cotton and other fibrous materials and consists in arrangements by means
of which I prevent the motion of the heart or cam used for raising and lowering
the copping or ring rail employed in a ring spinning or ring doubling machine
from being rendered irregular by the weight of the copping or ring rail when the
points of the heart or cam are passing the lifter bowl or roller-To accomplish
the object of this part of my invention I apply a brake or friction band to a pulley
mounted fast upon the shaft which carries the heart or cam which brake or
friction band will prevent the rotation of the heart or cam froin being accelerated
by the action of the weight of the copping or ring rail when the points of the
heart or cam are passing the lifter bowl or roller.

Materials.
I JOHN DODD of Oldham in the County of Lancaster Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN THE MACHINERY OR
APPARATUS KNOWN AS RING SPINNING MACHINES AND RING DOUBLING MACHINES
AND USED FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to the machinery or apparatus known as ring-spinning
machines and ring-doubling machines and used for spinning and doubling cotton
and other fibrous materials.
In order that my invention may be fully understood and readily carried into
effect I hereunto annex drawings in which drawings Fig. 1 is an end view partly
in section Fig. 2 a side elevation and Fig. 3 a plan of so much of a ring-spinning
or ring-doubling machine as is requisite to illustrate my invention Figs. 4 5 and 6
show portions of Figs 1. 2 and 3 respectively upon a larger scale and Figs. 7. 8. 9
10 and 11 are views which will hereinafter be more particularly referred to. The
same letters of reference are applied to corresponding parts throughout the whole
series of figures.
The first part of my invention refers to the copping or lifting motion used in
the machinery or apparatus known as ring-spinuing machines and ring doubling
machines and consists in arrangements by means of which I am enabled to readily
lower the copping or ring-rail into position for allowing the cops or bobbins to be
doffed from the spindles.
In the drawings hereunto annexed a is one of the end frames of a ring spinning
or ring doubling machine-Secured to the end-frame a are spindle-rails b which
carry the spindles c. I so mount the heart or cam & employed to raise and lower
the copping or ring-rails e e' upon the shaft f that such heart or cam d can be
slidden longitudinally upon the shaft f. Fast upon the shaft f is a friction
pulley g hereinafter more particularly described in reference to another part of my
invention. Formed upon one side of the friction pulley g is one part h of a clutch
box. Mounted upon the shaft f and capable of being turned thereon is a tube or
sleeve fast with which is one part h¹ of a clutch-box which is at times as will be
hereinafter pointed out, caused to engage with the other part h of the clutch box.
above-mentioned. k is a lever or frame mounted on the stud n and capable of
being turned thereon by means of which lever or frame the copping or ring-rails
e e' are raised and lowered. To the lever or frame k I secure a stud / upon which
I mount a bowl m. The heart or cam d acts upon the bowl m to raise and lower

page_text: the copping or ring-rails e e¹ in the well-known manner to "build" the cop by
means of the lever or frame k, the shaft o which carries the ratchet or shaper
wheel, the worm p worm-wheel q capable of being turned upon the stud n,
the volute wheels 7 and 8 mounted respectively upon the studs n t, the bevel-wheel u
toothed segment v, lifting levers w, mounted upon the shaft x, and the lifting
pillars y one only of which is shown in the drawing-I provide the bowl m with
a conical part m¹ so that when the heart or cam d is slidden longitudinally upon
the shaft the said heart or cam d will be caused to act on the smaller part of the
conical part m¹ of the said bowl m and allow that end of the lever or frame k upon
which the bowl m is mounted to ascend and so lower the copping or ring-rails e e¹
below their normal position.
Secured to the end-frame a is a bracket 1 provided with a stud 2—Mounted
upon the stud 2 so as to be capable of being turned thereon is the disengaging
lever 3-One arm of this lever 3 is formed as a handle 4 and the other arm of such
lever 3 is provided with a projection 3 for acting upon the incline 5 formed upon
the heart or cam d-To ensure that the projection 3ª be brought into the right
position for acting upon the incline 5 I provide the bracket 1 with a projecting
part 1 against which the handle 4 arrives when the said handle is raised.
When the lever 3 is turned by means of the handle 4 so t that the projection 3*
will be brought into the path of an incline 5 formed upon the tube or sleeve j and
so cause it to be slidden longitudinally in the direction indicated by the arrow A
against the force of a spring 6 one end of which abuts against the tube or sleeve j
while the other end of such spring16 abuts against a collar 7 fast upon the shaft f-
The heart or cam d which is secured to the tube or sleeve i will also be slidden
upon the shaft f in the direction indicated by the arrow A until the teeth or
projections h of the part h¹ of the clutch box will be drawn out of gear with the
teeth or projections h³ by means of which the heart or cam d is rotated, and thus
the motion of the heart or cam d will be arrested-The incline 5 is provided with
a stop or projection 5* which arrives against the projection 3* and prevents a
further rotation of the heart or cam d-By means of the incline 5 and stop or
projection 5 I cause the heart or cam d to be stopped in such position that the
copping or ring rails e el are at the bottom of their normal "lift" at which time
the sliding of the heart or cam d in the direction indicated by the arrow A will
have caused such heart or cam d to have arrived upon the smaller part of the
conical part m¹ of the bowl m and by this additional movement the copping or ring
rails will be allowed to descend below their normal position-Carried by the
lever or frame k so as to be capable of being rotated therein is the shaft o upon one
end of which shaft o is fixed the ratchet or shaper wheel 8-Near the other end
of the shaft o is secured the worm p which gears into the worm-wheel q secured to
the volute wheel r-To the lever or frame k I secure one end of a coiled spring 9
the other end of which spring 9 is fastened to the shaft o-The spring 9 becomes
charged with power during the formation of each set of cops-When the attendant
raises the clicks or pawls 10, 11 clear of the ratchet or shaper wheel 8 the spring 9
will be at liberty to turn the shaft o in the direction indicated by the arrow B
until the rotation of the shaft o is arrested by the stop 12 fast upon the shaft o
arriving in contact with the projection 13 formed upon the volute wheel r, at which
time the copping or ring-rails e el will have been lowered to their lowest normal
position.
When it is desired to doff the cops z from the spindles c the attendant with one
hand raises the clicks or pawls 10 and 11 clear of the ratchet or shaper wheel 8
and at the same time with the other hand raises the lever 3 until the projection 3*
is brought into the path of the incline 5-The raising of the clicks or pawls 10
and 11 as above described allows the spring 9 to rotate the shaft o until such
rotation is arrested by the stop 12 arriving in contact with the projection 13 which
will have allowed the copping or ring-rails e e¹ to descend to their lowest normal
position that is to say to the position which they occupy when commencing to

page_text: build a fresh set of cops--The raising of the lever 3 will cause the heart or cam d
to arrive upon the part m¹ of the bowl m as previously described and thus allows
the copping or ring-rails e e¹ to descend below their normal position at which time
the rotation of the heart or cam d will have been stopped. By such additional and
simultaneous lowering of the copping or ring-rails e, e¹ the yarn or thread is
enabled to be wound upon the spindles c below the bases of the cops 2.
Immediately the desired quantity of yarn or thread has been wound upon the
spindles c below the bases of the cops the frame is stopped and the cops may be
doffed from the spindles whilst leaving the yarn or thread between the delivery
rollers and the spindles unbroken.
To commence spinning or forming a fresh set of cops the machine is put in
motion and the clicks or pawls 10. 11 are caused to engage with the teeth of the
ratchet or shaper wheel 8 and at the same time the lever 3 is also turned or moved
so as to remove the projection 3ª clear of the stop or projection 5ª and incline 5
and allow the spring 6 to slide the heart or cam & upon the shaft f in a direction
opposite to that indicated by the arrow A and cause the teeth or projections h* of
the part h¹ of the clutch-box to engage with the teeth or projections h³ of the
part h of the clutch-box and allow the heart or cam d to arrive upon the cylindrical
part m of the bowl m so that the copping or ring-rails e e¹ will be caused to
ascend to their lowest normal position thus commencing the formation or building
of a fresh set of cops. I have above-described the clicks or pawls 10. 11 as being
disengaged from the teeth of the ratchet or shaper wheel 8 by the attendant.
Figs. 8 and 9 illustrate a method by which the clicks or pawls 10. 11 will be caused
to be disengaged from the teeth of the ratchet or shaper wheel 8 without attention
on the part of the attendant, soon after the handle 4 is raised. Secured to the
handle is a projecting bracket 4 which when the handle 4 is raised into the
position in which it is indicated by full lines in Fig. 8, is placed above projecting
parts 10 11 formed upon the clicks or pawls 10. 11 respectively.
The oscillations of the frame k by means of the pawl or click 10 cause the
ratchet or shaper wheel 8 to be rotated in the usual manner-Upon the completion
of a set of cops or when it is desired to doff them the attendant will raise the
handle 4 into the position in which it is indicated by full lines. When the lever
or frame k rises the projecting parts 10" 11" will arrive against the projecting
bracket 4* and the clicks or pawls 10. 11 will be disengaged from the teeth of the
ratchet or shaper wheel 8. The shaft o will then be free to be rotated by the
coiled spring 9 as previously described.
In some cases I employ a lever operated by the attendant to assist the spring 6
above-mentioned in moving the part h¹ of the clutch-box into gear with the other
part of the clutch-box-This modification of my invention is shown in Figs. 10
and 11 of the drawing hereunto annexed Fig. 10 being an end elevation and Fig. 11
a plan of so much of a ring-spinning or ring-doubling machine as is requisite to
illustrate this modification of my invention.
Secured to the end-frame a is a bracket 14 provided with a stud 15. A lever 16
is mounted upon the said stud 15 so as to be capable of being turned thereon. One
end of the lever 16 is formed as a handle 16 the remaining end 16 of the lever 16
being adapted to receive a stud 17 formed upon a jaw 18 situate in a groove 19
formed around the boss of the tube or sleeve j. The attendant by forcing the
handle 16* in the direction indicated by the arrow C may assist the spring 6 in
moving the heart or cam d. from the conical part m' of the bowl m to the cylindrical
part m³ of such bowl m and in causing the copping or ring-rails & e¹ to be raised
into position for commencing the building or formation of a fresh set of cops.
A further part of my invention is shewn in Figs. 10 and 11 previously referred
to and consists in arrangements by which I am enabled to govern the winding
of the yarn or thread upon the spindles of the machinery or apparatus known
as ring-spinning and ring-doubling machines and used for spinning and doubling

page_text: cotton and other fibrous materials, so that the layers of yarn or thread are wound
upon the cops or bobbins in alternately varying spirals.
In accomplishing the object of this part of my invention I employ a double-
throw heart or cam 20 baving one throw 20 of the heart or cam 20 of greater lift
than the other throw 20° of such heart or cam 20. The heart or cam 20 acting
in conjunction with the bowl m for raising and lowering the copping or ring-
rails and the circumference of the heart or cam 20 being formed as above
described will cause the layers of yarn or thread to be wound upon the cops or
bobbins in alternately varying spirals.
A further part of my invention relates to the machinery or apparatus known as
ring-spinning machines and ring-doubling machines and used for spinning and
doubling cotton and other fibrous materials and consists in arrangements by means
of which I prevent the "back-lash" of the gearing through which the heart or cam
used for raising and lowering the copping or ring-rail employed in a ring-spinning
or ring-doubling machine from allowing the motion of the said heart or cam to be
rendered irregular by the weight of the copping or ring-rail when the points of the
heart or cam are passing the lifter bowl or roller-This part of my invention is also
illustrated by Figs. 1, 2, 3, 4, 5, 6 10, and 11 above referred to.
To accomplish the object of this part of my invention I form upon the part h of
the clutch box which is fast upon the shaft fa pulley g provided with flanges g³ g*
and apply to such pulley g a brake or friction band 21 one end of which is secured
to a stud 22 secured to the end-frame a-Upon the remaining end of the brake or
friction band 21 is hung a weight 23-The brake or friction band 21 will prevent
the rotation of the heart or cam d or 20 as the case may be from being accelerated
by the action of the weight of the copping or ring-rails e. e¹ when the points of the
heart or cam d or 20 are passing the lifter bowl or roller m.
Instead of causing the brake or friction band 21 to act upon a pulley g formed
upon the part h of the clutch box I in some cases cause such brake or friction
band 21 to act upon a pulley mounted upon the shaft f.
Although I have shewn and described the arrangements by means of which the
copping or ring-rails are enabled to be readily lowered into a position suitable for
allowing the cops or bobbins to be readily doffed from the spindles and the
arrangements by means of which the yarn or thread is caused to be wound upon
the cops or bobbins in alternately varying spirals and the arrangements by means
of which the "back-lash" of the gearing through which the heart or can aforesaid
raises and lowers the copping or ring-rails employed in a ring-spinning or ring-
doubling machine is prevented from allowing the motion of the said heart or cam
to be rendered irregular by the action of the weight of the copping or ring-rails
when the points of the heart or cam are passing the lifter bowl or roller, as being
all applied to one and the saine machine I would have it understood that each of
such arrangements may be applied to a machine alone or along with either or both
of the others.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
1. For use in each of the machines known as ring-spinning machines and ring-
doubling machines the arrangements herein before described, constructed, arranged,
and operating substantially as herein before described in reference to and shown in
and by the drawings hereunto annexed by which arrangements the copping or
ring-rails employed in each of such machines are enabled to be readily lowered
into position for allowing the cops or bobbins to be doffed from the spindles and by
which arrangements yarn or thread is enabled to be wound upon the spindles
below the cops when required.
2. For use in each of the machines known as ring-spinning machines and ring-
doubling machines the arrangements herein before described by means of which the

page_text: layers of yarn or thread are caused to be wound upon the cops or bobbins in
alternately varying spirals substantially as herein before describe which arrange-
ments consist in a double throw heart or cam 20 constructed, arranged and
operating substantially as herein before described in reference to and shewn in and
by the drawings hereunto annexed.
3. For use in each of the machines known as ring-spinning machines and ring-
doubling machines, the brake or friction band 21, applied arranged and operating
substantially as and for the purpose herein before described and shown in reference
to and in and by the drawings hereunto annexed.
