Improvements in Ring Spinning Frames.
We, JOSEPH WILKINSON, of Acre Lane, Oldham, Manager, and WILLIAM
NEEDHAM WILKINSON, of St. John's Road, Longsight, Agent, both in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to frames that are employed in ring spinning for building
a cop of yarn on a spindle, or on bobbins or spools, and the objects of this inven-
tion are to regulate the twist of the yarn, and the tension, and to obviate
balooning.
In this invention we construct a frame in which ring rails and spindles of the
usual description are employed.
At one end of said frame, and for connecting with the driving shaft on which is
the drum or tin roller, we place a toothed wheel which we mount on a shaft running
parallel to the driving shaft. We attach a pair of bevel wheels supported by
brackets connected to the central part of this toothed wheel, said bevel wheels
gearing into a pair of bevel wheels placed loosely on aforesaid shaft, by which
means sun and planet motion is obtained. On this same shaft we place a loose
pinion which we connect to one of the bevel wheels placed on shaft as herein last
described. In conjunction with this pinion we place a rack in a transverse position
arranged so as to be placed in or out of gear as may be required. On one side of
said rack, and preferably near the end, we place a bowl or a stud. We place on a
shaft in proximity to aforesaid rack, a cam or an eccentric of suitable shape, and on
the same shaft a spaced wheel. We either connect this shaft by means of aforesaid
spaced wheel and bevel gearing to a longitudinal shaft on which is mounted a
variable toothed wheel of an eccentric form placed in connection with the wheels
that are attached to the rollers delivering yarn, or geared up to the back roller.
We place a pinion on a swing shaft which is supported by levers from a shaft
running longitudinally or parallel with the driving shaft. This pinion is kept in
gear with aforesaid variable toothed wheel by means of a cam groove which retains
the end of swing shaft carrying pinion and corresponds to the shape of variable
toothed wheel. Motion is communicated to this pinion by means of toothed wheels
which are placed on aforesaid swing shaft, and also on shaft which supports said
swing shaft, from the shaft carrying bevel gearing as described for obtaining sun
and planet motion.
Before commencing to build a cop on to a spindle by means of a machine con-
structed substantially as herein before described, in order to regulate the twist of
the yarn and obviate balooning, we cause the wheels which are attached to the
rollers delivering yarn to rotate at a variable speed by the action of the cam or
eccentric which regulates the speed of said rollers, by placing the long end of said
cam or eccentric in contact with the bowl which is attached to rack: by the action
of this eccentric which is gradually lifted by means of a spaced wheel on same shaft,
the speed of the rack is regulated, as is also the speed of the pinion attached to
bevel gearing giving sun and planet motion. When said eccentric has performed
the function of regulating the speed of the delivery rollers which is thereby slowest
at the commencement of the formation of the cop and increased as the upper and
broader part of the cop bottom is formed, said eccentric is by means of aforesaid spaced
wheel placed out of gear, and the delivery of yarn proceeds and is regulated
entirely by the variable toothed wheel or cam herein before described. In com-
bination with aforesaid variable toothed wheel we place on same shaft a cam or

page_text: eccentric of suitable form so as to lift the ring rail up and down in order to lay on
the yarn either quickly or more slowly the lifter is by these means always in the
right place at the right time.

Improvements in Ring Spinning Frames.
We, JOSEPH WILKINSON of 24 Acre Lane, Oldham, Manager, and WILLIAM 1
NEEDHAM WILKINSON of 10 St. John's Road, Longsight Agent, both in the
County of Lancaster 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 :-
This invention relates to frames that are employed in ring spinning for building 1
a cop of yarn of any
fibrous material on a bare spindle, or on bobbins or spools, and
the objects of this invention are to regulate the twist of the yarn, and the tension,
and to obviate ballooning. In this invention we attain the object set forth by the
mechanism hereinafter described and illustrated in the accompanying drawings. In
these drawings similar letters refer to similar parts throughout the several views. 2
Fig. 1 is a front view, Fig. 2 a plan, Fig. 3 an end view of a ring spinning frame,
constructed according to this invention. Fig. 4 is a section on line A A in
Figs. 1 and 2.
We construct a frame in which ring rails cand spindles d of the usual
description are employed. At one end of the frame b for the purpose of forming a
connection with the driving shaft e on which is the drum or tin roller we place a
toothed wheel which we mount on a shaft running parallel to the driving shaft.
To the central part of aforesaid toothed wheel we attach a pair of bevel
wheels, supported by brackets that are connected to face of wheel The
bevel wheels k, k¹, which pass through openings in face of wheel g gear into a
pair of bevel wheels 1, l', placed one on either side of wheel g loosely on the shaft /
by which means sun and planet motion is obtained. We place a pinion m loosely
on the shaft and connect this pinion to the back of the bevel wheel l.
g.
We place a rack m² in a transverse position and arranged so as to be put in or
out of gear with aforesaid pinion m by means of a bell crank lever m² as shown or
other mechanical equivalent. On one side of rack m' and preferably near the end
of said rack we place a bowl p or a stud. On shaft n that is in proximity to the
rack m' we place a cam or an eccentric y of suitable shape, and on the same shaft a
spaced wheel u. We connect the shaft n by means of aforesaid spaced wheel u, the
bevel wheel o, and a worm and worm wheel p, p, or other equivalent gearing to the
longitudinal shaft on which is mounted a variable toothed wheels of an eccentric
form.
The
By means of the wheels t, t', t, the aforesaid variable toothed wheels is placed
in gear with the wheels e, u, v, v³, that are connected directly or indirectly to the
rollers u.
We place a pinion s'on a swing shaft which is supported by levers &³
from a shaft running longitudinally or parallel with the driving shaft e.
pinion s' is kept in gear with aforesaid variable toothed wheels by means of a cam
groove as shown in Fig. 4 which corresponds to the shape of said variable toothed
wheels.
This cam groove which is attached to the wheel t by the brackets.
revolves with the wheel and retains a bowl .' which is fitted to the end of swing
shaft carrying the pinion s¹ and causes said pinion to follow the outline or form
of the eccentric or variable toothed wheels and by these means to be always kept
in gear with the wheels whether in consequence of the shape of the wheels the

page_text: point of contact with the pinion s¹ is nearer to, or farther from the shaft r. Motion
is communicated from the shaft / carrying bevel gearing to the pinion s¹ by means
of the toothed wheel which is placed on the swing shaft, and the toothed
wheel placed on shaft w which supports said swing shaft. In order to lift the
ring rail up and down for the purpose of laying on the yarn either quickly or more
slowly, we place in combination with aforesaid variable toothed wheels a cam or
eccentric in any suitable position on the shaft r. This cam is preferably of the
same form or outline as the variable toothed wheels and is placed relatively in the
same position on the shaft as said variable toothed wheel. By the intervention of
a lever or levers the position of the ring rail c is adjusted. We cause the wheels
that are attached to the rollers delivering yarn, and consequently the rollers them-
selves to rotate at a variable speed for the purpose of regulating the twist of the
yarn, and to obviate ballooning by the action of aforesaid eccentric or variable
toothed wheel *.
Before commencing to build a cop either on to a bare spindle or putting the yarn
on bobbins or spools by means of a machine constructed substantially as herein-
before described we place the rack m¹ in such a position that the end g' of the
eccentric q may be in contact with the bowl which is attached to the rack m¹.
Motion is then transmitted from the driving shaft e by means of the pinion g' on
driving shaft and the toothed wheel g on the shaft h causing said wheel to revolve
and carry round with it the bevel wheels k, k¹, by these means motion is given to
the toothed wheel through the bevel wheel and the pinion g' thus actuating
the toothed wheel c which revolves the wheel c' and with it the pinion ; the
variable toothed wheels is thus put in operation, and by the intervention of afore-
said cam or eccentric y the ring rail c is raised or lowered so as to lay on the yarn
either quickly or slowly. The speed of the rollers u delivering the yarn is also
regulated by the action of the cam or eccentric 9, the long end q¹ being placed,
after doffing and before commencing to build a cop of yarn, in contact with the
bowl in the position shown in Fig. 3. When the rack m¹ is caused to be moved
forward by the action of the bevel wheel and the pinion m the end of the cam q
is gradually raised by the spaced wheel thereby regulating the speed of the
rack m until the wheel u is thrown out of gear by the termination of the geared
portion or open space u¹. When the eccentric has thus performed the function of
regulating the speed of the delivery rollers u which is thereby slowest at the
commencement of the formation of a cop and increased as the upper and broader
part of the cop bottom is formed, said eccentric is as herein before described placed
out of gear and the delivery of yarn proceeds and is regulated entirely by the
variable toothed wheel or cam s. By these means a cop of yarn may be built
either on the bare spindle, or the yarn may be put on bobbins or spools.
The several shafts and gearing to which reference has herein before been made
may occupy other positions in a ring spinning frame, than those shown in drawings,
and said shafts and gearing may be placed higher or lower or nearer to or
farther from the front of the frame without departing from the nature of this
invention.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1st. In a ring spinning frame that is employed for spinning yarn of any fibrous
material, the use of a variable toothed wheel of an eccentric form for operating the
rollers delivering yarn and regulating the speed of said rollers in the manner and
for the purpose substantially as herein before described.
2nd. In a ring spinning frame that is employed for spinning yarn of any fibrous
material the use of an eccentric in combination with a spaced wheel for rotating
same, bevel gearing working with sun and planet motion for operating a rack whose
speed is governed by aforesaid eccentric in order, to regulate the speed of the

page_text: delivery rollers all in the manner and for the purpose substantially as herein before
described.
3rd. In a ring spinning frame that is employed for spinning yarn of any fibrous
material the use of the aforesaid variable toothed wheel and the aforesaid eccentric
either in combination, or separately for regulating the speed of the delivery rollers
in the manner and for the purpose substantially as herein before described.
4th. In a ring spinning frame that is employed for spinning yarn of any fibrous
material the combination of the several parts forming said machine for the
purpose and in the manner substantially as herein before described and illustrated.
