Improvements in Ring Spinning Apparatus.
I JOHN HARGREAVES of 151 Deane Church Lane, Bolton, in the County of
Lancaster, Mill Overlooker, do hereby declare the nature of this invention to be
as follows:-
My said invention relates to improvements in ring spinning apparatus for effecting
and facilitating the spinning of yarns. According to my invention I employ a ring
traveller of a novel description consisting of an annular body such as a hollow
cylinder with a projecting flange or with projecting wings the said flange or wings
entering a groove or annular recess formed in a ring secured to the ring rail, the
object being that the ring traveller shall easily revolve in the ring but will not be
liable to be lifted out by the pull of the yarn. In conjunction with this revolving
ring traveller I use a light yarn guide formed with jaws or spring fingers and this
guide I spring upon the upper part of the ring traveller, slots being cut in the
upper part of the ring traveller to permit of the engagement of the yarn guide
with the ring. The object of the slots in the ring traveller is to allow the yarn
guide to approach towards or recede from the spindle or partly wound cop so as to
avoid breaking the yarn by putting too much strain upon it. The yarn is brought
from the delivery rollers and passed through the legs or jaw or spring fingers or
other suitable orifice or curl in the yarn guide and thence to the spindle or cop.
When the frame is at work the revolution of the spindle causes the yarn to pull
on the yarn guide and the impulse being imparted by the yarn guide to the ring
traveller, the latter revolves in the ring on the ring rail. The traveller thus
practically consists of two relatively movable parts, the yarn guide and the revolving
ring traveller, and the ease of motion and yielding character of such duplex
appliance enables me to spin with less fear of breakage than heretofore, especially
when spinning upon the bare spindle. I also provide improved means to stop the
frame when the filling of the cops is complete. This I effect by placing a catch
on the chain which lifts the copping rail. As this chain advances with the
increased lift of the rail, the catch is at last brought within range of a trigger
which holds a cbain wheel against the downward pull of a weight or spring. On
the disturbance of the trigger the said chain wheel is released and pulling on a
slack chain moves the sliding bar which carries the belt shifter and so stops
the frame. I might also make provision for flattening the inclined sides of the
foot of the cop more fully than is done at present. Ordinarily the foot of the
cop is rounded and is susceptible" of becoming loose. Under my improvement
instead of using the ordinary chain wheel with a raised part for lessening the lift
of the copping rail at this point, I form the chain wheel without any such
enlargement and form its periphery with teeth which engage with a rack on a bar
which carries a roller to bear on the chain. As the chain wheel revolves, the rack
bar is advanced until the roller pushes against and takes 'up the chain whereupon
the copping rail is caused to act in such a manner as to produce the required flat
inclined sides at the foot of the cop.

Improvements in Ring Spinning Apparatus.
I JOHN HARGREAVES of 151 Deane Church Lane, Bolton, in the County of
Lancaster, Mill Overlooker, 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 and accompanying drawings:
When
My said invention relates to improvements in ring spinning apparatus for
effecting and facilitating the spinning of yarns. According to my invention
I employ a ring traveller of a novel description consisting of an annular body such
as a hollow cylinder with a projecting flange or with projecting wings the said
flange or wings entering a groove or annular recess formed in a ring secured to
the ring rail, the object being that the ring traveller shall easily revolve in the
ring but will not be liable to be lifted out by the pull of the yarn. In conjunction
with the revolving ring traveller 1 use a light yarn guide formed with jaws or
spring fingers and this guide 1 spring upon the ring traveller, slots being cut in the
ring traveller to permit of the engagement of the yarn guide with the ring. The
object of the slots in the ring traveller is to allow the yarn guide to approach
towards or recede from the spindle or partly wound cop so as to avoid breaking
the yarn by putting too much strain upon it. The yarn is brought from the
delivery rollers and passed through the legs or jaw or spring fingers or other
suitable orifice or curl in the yarn guide and thence to the spindle or cop.
the frame is at work the revolution of the spindle causes the yarn to pull on the
yarn guide and the impulse being imparted by the yarn guide to the ring traveller,
the latter revolves in the ring on the ring rail. The traveller thus practically
consists of two relatively moveable parts, the yarn guide and the revolving ring
traveller, and the ease of motion and yielding character of such duplex appliances
enables me to spin with less fear of breakage than heretofore, especially when
spinning upon the bare spindle. I also provide improved means to stop the
frame when the filling of the cops is complete. This I effect by placing a catch
on the chain which lifts the copping rail. As this chain advances with the
. increased lift of the rail, the catch is at last brought within range of a trigger
which holds a chain wheel against the downward pull of the copping rail. On the
disturbance of the tiigger the said chain wheel is released and pulling on a slack
chain moves the sliding bar which carries the belt shifter and so stops the frame.
I also make provision for flattening the inclined sides of the foot of the cop more
fully than is done at present. Ordinarily the foot of the cop is rounded and is
susceptible of becoming loose. Under my improvement instead of using the
ordinary chain wheel with a raised part for lessening the lift of the copping rail at
this point, I form the chain wheel without any such enlargement and form its
periphery with teeth which engage with a rack on a bar which carries a roller to
bear on the chain. As the chain wheel revolves, the rack bar is retracted from
the chain until the roller is withdrawn from contact with the chain which by that
time is wound upon the taking up wheel and the cop bottom is formed.
My invention will be more fully understood by a reference to the annexed sheet
of illustrative drawings to which I will now refer.

C
upon
Referring to the subject matter of these figs. in their respective order I will refer
first to the annular loose ring traveller. In Fig. 1 the ring a is fixed in the ring
rail in the usual manner. This ring is formed with a central gallery a¹ which
runs the loose annular body or ring b. This ring is formed with projections b
on the under side which bear on the under side of the gallery a' and to support it
on the upper side of the gallery I cause the wire of the yarn guide'c to extend
through the side of the ring b, the said extending wires resting on the top side of
the gallery as appears most plainly in the plan view Fig. 2. The ring 6 is thus
supported on the gallery between the wires c and the projections and runs freely
thereon in obedience to the pull of the yarn on the eye of the guide c while at
the same time it cannot be lifted out of the ring. The ring b with its yarn guide c
appears clearly in Fig. 3. This however is only one way of supporting the ring b
in the ring a.
As a matter of fact the yarn guide c is not in my opinion the best
for the production of good yarn and I prefer to use the yarn guide illustrated in
the following figs. The form of this improved yarn guide is best seen in Fig. 6.
The guide which is lettered d is forked or formed with spring fingers at one end
while the other end d² is also jawed. The novel part of such a yarn guide consists
in the tongue d³ which exists between the jaws d2 and by sliding or bearing against
the inner circumference of the ring steadies the yarn guide when at work. The
shape of the yarn guide in plan is seen at Fig. 7. This yarn guide is shown
applied to a loose ring traveller b at Figs. 4 and 5. The ring traveller is slotted
in the sides as clearly shown in the drawings, and I spring or place one arm of the
fork into one of the slots. I also spring one of the members of the jaw d²:
into the other slot, the other spring finger and jaw-half resting on the top of the
ring b. The object of the slots is to allow the yarn guide to approach towards or
recede from the spindle or partly wound cop as indicated for example in Fig. 8 to
avoid breaking the yarn or putting too much strain upon it. The ring b shown in
Figs. 4 and 5 might be carried in the ring a in any convenient manner.
example the pins 2 projecting from the ring might run in a groove turned or
formed in the supporting ring a, or lugs or projections, such as b¹ in Fig. 3, might
run in confined grooves or annular slits in the inner circumference of the carrying
ring. The improved yarn guide d with tongue d³ might be carried in a loose
revolving ring such as 6 or it might slide on a fixed ring like an ordinary traveller
as shown for instance in Figs. 9 and 10 where the fork and jaw of the yarn guide &
slide on the gallery a¹ of a fixed ring a. I do not confiue myself to any particular
application of the improved yarn guide so long as it is made with the supporting
tongue d³. An additional improvement in the form of the thread guide d is shown
at Fig. 11. In this case I form the fork d¹ with a cross bar d thus strengthening
and steadying the fork. In using the improved yarn guide the yarn e is brought
from the delivery rollers and passed between the legs of the fork d¹ and thence to
the spindle as in Fig. 9 or to the cop gas in Fig. 10. When the yarn guided is
used in conjunction with loose revolving ring traveller & running in a fixed
ring a, the traveller practically consists of two relatively noveable parts i.e. the
yarn guide d and the loose ring b. The revolution of the spindle causes the yara
to pull on the yaru guide d and the impulse being imparted by the yarn guide to
the ring traveller b, the latter revolves in the fixed ring a on the ring rail. The ease
of motion and the yielding nature of such duplex appliances enables me to spin
For

spindle.
My invention also refers to improved means for stopping the frame when the
filling of the cops is complete. This is illustrated in Fig. 12. I place a catch h on
the chain i which lifts the copping rail j by means of the levers k and pokers l, in
the well known manner. As this chain is shortened by the taking up wheel
in the ordinary manner the catch h advances until it strikes against a trigger m
which engages with a chain wheel n which holds the other end of the chain i against
the weight of the copping rail. On the pushing aside of the trigger m the chain
wheel n is released and allows the copping rail to fall. The revolution of the
chain wheel n by the pull of the falling copping rail, causes another wheel on the
same shaft n which carries the wheel n to revolve and wind on a piece of slack
chain o which rotates the wheel
to some extent and by operating the shaft p¹
moves the sliding bar by a lever or any other convenient connection and thus shifts
the belt fork and stops the frame. The trigger m is normally maintained in gear
with the tooth on the chain wheel n by means of a spring m³ which appears in
dotted lines in Fig. 12.
My invention finally relates to improved means for flattening the inclined sides
of the foot of the cop to a greater extent than is at present the case. Ordinarily
the foot of the cop is rounded and is susceptible of becoming loose. According to
my improvement instead of using the ordinary chain wheel q (see Fig. 12) with a
raised part q' for lessening the lift of the copping rail ; at this point, the said chain
wheel has no such enlargement, but as shown in Fig. 13 I form the said wheel
with teeth which engage with a rack on a sliding barr which carries a roller s at
its extremity, the said roller bearing against the taking-up chain i. As the chain
wheel revolves by the taking up of the chain the rack bar r is pushed in the
direction indicated by the arrow the roller s deflecting the chain less and less as the
rail is lifted until the roller is entirely withdrawn from contact with the chain
which by that time has become wound upon the taking-up wheel and the formation
of the cop bottom is completed.
The required flattening of the rounded cop foot is thus obtained.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. In combination with a ring or bolder formed in or secured to the ring rail, the
loose revolvable traveller ring b carrying or fitted with a suitable yarn guide
substantially as described and shown.
2. The loose revolvable traveller ring 6 formed with slots to receive a yarn guide
such as d, substantially as described and shown.
3. The improved yarn guide d with a fork at one end and a jaw formation at
the other, the improvement consisting in forming the jawed end with a tongue d³
for the purposes and substantially as described and shown.
4. The improved yarn guide d having a fork at one end and a jaw at the other
the jawed end being furnished with a tongue d³ and the forked end having a cross
bar d for the purposes and substantially as described and shown.
5. The improved means for automatically stopping the working of the frame
when the cops are finished, substantially as described and as indicated in Fig. 12.
6. The improved means for effecting the flattening of the rounded ends of cop
bottoms substantially as described and as shown in Fig. 13 of the drawings.
