Improvements in Means for Facilitating the Spinning of Textile
Fibres.
We RICHARD TODD of Heather Bank, Broomfield Road, Heaton Chapel, in
the County of Lancaster, Manufacturer, and JESSE AINSWORTH STOTT of
5 Cross Street, Manchester, in the aforesaid county, Architect, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to improved means for facilitating the spinning of yarns
upon the bare spindle of the ordinary diameter and is applicable chiefly to frames,
of the throstle type. The improvements apply more particularly to spinning,
appliances in which a flexible or whip traveller is used similar for example to the
apparatus described by one of us, the said Richard Todd, in the Specification of
his Patent No. 20487 of 1894. In the said specification is indicated a ferrule or
ring fitting the spindle loosely and carrying a fixed rigid or elastic arm or whip,
traveller having an eye at the upper eud through which the yarn passes to the cop
or spindle. The fact of the said arm or whip traveller being a fixture on the
ferrule or ring is the source of many disadvantages both in the course of
manufacture and use. The arm is apt to break at the bend and if such should
happen or should the arm or whip traveller become otherwise unfit for use, the
whole ferrule or ring requires to be removed from the ring or race in which it is
retained by bent fingers and either repaired or thrown away, both time and
material being thus sacrificed. Under our present invention we remedy these
defects by making the arm or whip traveller separate from the ferrule or ring and
forming both so that the arm can be readily attached or detached at pleasure and
without removing the ferrule from the race. We do not confine ourselves to any
particular means for effecting this ready attachment and detachment. The most
convenient is to form any suitable spring snap joint, the socket to receive the butt
of the whip traveller being formed either directly on the ferrule or ring or on an
arm or projection therefroin. When the socket is formed in a projection from the
ferrule, the arm or whip traveller may be made perfectly straight from butt to tip
or eye which is a great convenience for cheap manufacture. We might bend or
form the foot of the arm so as to form a spring butt snapping into a recess in the
socket or we might form the socket with a spring catch to engage with the butt of
the arm.
When a spring snap joint is used, a tongue, prolongation or presser may
be provided to effect a more ready disengagement and separation of the arm from
the ferrule. A spring snap joint however is not essential as any other convenient
means such as a jamb ring or other ready means might be used to effect the purpose
of our invention which is to render the arm or whip traveller separate from and
readily attachable to and detachable from the ring or ferrule.
By means of our invention we effect great economy both in time and material
and remove a source of mischief and loss which militated greatly against the
commercial success of this type of spinning appliance.
Our invention also relates to improved means for more readily and easily
mounting the aforesaid ring or ferrule which carries the whip traveller, in working
position. Under the construction set forth in the said prior specification of
Richard Todd the said ring or ferrule is provided at the foot with bent fingers,
two being the most suitable number, which fingers run in a race formed in a socket
ring with cap, the said socket ring being carried in a lifting rail or part beneath

page_text: the cop. As it is extremely desirable if not indeed essential to have the confining
race as small in diameter as possible so as to diminish the frictional resistance or
drag upon the said fingers, it was under the said prior arrangement necessary to
introduce the fingers first into the socket ring and bend them out afterwards, or
otherwise during the process of introduction. This was an operation which took
considerable time and care and interfered materially with the economical use of
the invention. Under our present invention the fingers can be properly bent an I
shaped before being placed in the race of the socket or carrying ring. To effect
this we so form the ferrule that it becomes possible and easy to slip the bent
fingers of the ferrule into working position in the race. Under the method which
is most likely to be adopted we cut out or shape the sides of the ferrule opposite
to the fingers so that the sides of the ferrule offer no obstruction to the insertion
of the bent fingers. One result of so cutting out the ferrule is that it becomes
thereby greatly lightened. By a modification we might make the ferrule in two
halves separately applied and then snapped or otherwise firmly secured together.
To facilitate the application of the said cap or cover of the socket or carrying ring
we make it of such a size that it can be passed down through the curbing sleeve
which surrounds and confines the whip traveller. As this materially restricts the
diameter of the said cap we use a secondary cover plate to cover in the socket or
carrying ring and this cover plate may be in two or more parts. The cover plate
is cut out in the centre to receive the cap. Thus the cap may be made small
enough to pass through the curbing sleeve without reducing the size of the carrying
or socket ring. As a modification we might form the socket or carrying ring with
an inwardly overhanging ledge which would receive the cap and enable the said
cover plate to be dispensed with.

Improvements in Means for Facilitating the Spinning of Textile

We RICHARD TODD of Heather Bank, Broomfield Road, Heaton Chapel, in the
County of Lancaster, Manufacturer, and JESSE AINSWORTH STOTT of 5 Cross-
Street, Manchester, in the aforesaid county, Architect, do hereby declare the
nature of this invention and in what manner the same is to be performed to be

page_text: As it is.
Under our present invention we remedy these defects by making the arm or whip
traveller separate from the ferrule or ring and forming both, so that the arm can
be readily attached or detached at pleasure and without removing the ferrule from
the race.
We do not confine ourselves to any particular means for effecting this
ready attachment and detachment. The most convenient is to form any suitable
spring snap joint, the socket to receive the butt of the whip traveller being formed
either directly on the ferrule or ring or on an arm or projection therefrom.
When
the socket is formed in a projection from the ferrule, the arm or whip traveller may
be made perfectly straight from butt to tip or eye which is a great convenience for
cheap manufacture. We might bend or form the foot of the arm so as to form a
spring butt snapping into a recess in the socket or we might form the socket with
a spring catch to engage with the butt of the arm. When a spring snap joint is

the arm or whip traveller separate from and readily attachable to and detachable

in time and material and remove a source of mischief and loss which militated
greatly against the commercial success of this type of spinning appliance. Our
invention also relates to improved meaus for more readily and easily mounting the
aforesaid ring or ferrule which carries the whip traveller, in working position.
Under the construction set forth in the said prior specification of Richard Todd
the said ring or ferrule is provided at the foot with bent fingers, two being the most
suitable number, which fingers run in a race formed in a socket ring with cap, the
said socket ring being carried in a lifting rail or part beneath the cop.

the cap.
In order that our said invention may be fully understood we will now proceed to.
describe the same more particularly reference being had to the annexed two sheets:
of illustrative drawings.
On Sheet 1-
Fig. 1 is a general view of a spindle carrying a wound on cop of yarn and

page_text: Figs. 2 to 16 illustrate various modes of rendering the elastic or whip traveller
readily attachable to and detachable from the arm of the ferrule or part mounted
loosely on the spindle.
On Sheet 2-
Figs. 17 to 20 show an improved mode of cutting out or shaping the ferrule or
loose part mounted on the spindle so that it can be inserted into position in the
ring socket after the fingers at the foot of the ferrule have been bent to the proper
shape. Figs. 21 and 22 show a mode of making the arms of the ferrule readily
attachable and detachable.
Figs. 23 and 24 show our improved modes of introducing the cap or cover of the
socket ring through the curbing sleeve and of retaining the socket and cap in
position.
Referring to Sheet 1 of the drawings, Fig. 1 has been inserted chiefly for the
purpose of making the general arrangement and construction of the spindle and
flexible whip traveller more clear to the reader.
The spindle A is supported in the bolster rail in the ordinary manner and is
driven from the whirl A'. In the fig. a cop B is shown wound on the spindle.
The flexible arm or whip traveller C is carried on an arm D₁ of the ferrule D
which is loosely mounted on the spindle, a balancing arm D 2 exists on the other
side of the ferrule. The ferrule D has projecting fingers D3 which run in a space
between the two halves of a socket ring E E', the said socket ring being held in a
lifting rail F which rises and falls so as to correspondingly raise and lower the
eye C¹ of the whip traveller C. The space behind the ledges constituting the rail
to receive the fingers D 3 forms an oil chamber to contain lubricant. Above the
rail F and carried in another rail F¹ is a curbing ring which surrounds the cop and
prevents the whip traveller C from flying outward by centrifugal force. When the
apparatus is at work and the building of the cop B is in progress, the whip
traveller C is rotated by the draw of the yarn in the same direction as the
revolution of the spindle and the yarn is spun and drawn through the eye C¹ just
as in the case of a ring traveller.
But suppose the yarn to be winding on the bare spindle or cop sleeve or on any
part of the cop where from the directness of the pull or from other causes a strain
greater than usual is thrown upon the yarn then instead of pulling upon an
unyielding object like the ordinary traveller (which only runs with greater friction
and hangs further back the more directly radially the yarn pulls upon it) under
our improvement the yarn pulling on the elastic arm C draws the eye C¹ close up
to the spindle or cop and canting the ferrule D on the spindle binds it thereon or
causes it to have more frictional contact therewith so as to accelerate its speed
Eo that the whip traveller offers less resistance and breakage of the yarn is
prevented.
This general sketch of the operation of the flexible whip traveller and parts
will assist the reader to follow more intelligently the improvements which
constitute our present invention.
The general principle as disclosed in Todd's specification has never been
followed up or made practically and commercially successful because of the
insufficiency and impractical nature of the details.
For example it has hitherto never been proposed to do otherwise than make the
flexible arm C in one piece with the ferrule D. Such a method of construction is
subject to the disadvantage that the ferrule, and arm are difficult to make in one
piece and are easily broken. The result of such a breakage is that not only the
arm but the ferrule also is rendered useless and the ferrule requires to be removed
and renewed.
According to our invention we make the flexible arm C easily attachable and
detachable from the ferrule so that if the flexible arm should be disabled or broken
it can easily be replaced without disturbing the ferrule. This detachability of the
flexible arm or whip traveller C from the ferrule is the essence of this portion of

page_text: our invention.
It will of course be evident that various means for quickly
attaching and detaching the arm or whip traveller might be used.
We do not confine ourselves to any particular method but in order to give
illustrations of several ways in which it can be done we have appended in Sheet 1
illustrations of several methods which we have tested and found efficient. In the
drawings each fig. as a rule covers and includes a sectional view and a plan.
For example as in Fig. 2 we form the arm D' of the ferrule D with an oblong
socket D 4 or aperture and we form the tail of the flexible arm C with a spring
elbow which snaps into the oblong socket the curved end of the elbow entering a
hole in the side of the socket. By pinching together the projecting portion of the
elbow at the foot the arm C can be disengaged and drawn out. Fig. 3 shows a
similar arrangement the free end of the spring elbow on the arm C having a
stamped out projection C 2 which enters a similarly shaped out aperture or recess
in the side of the socket D4. The free end of the elbow projects above the
socket D 4 and by pinching this towards the arm C, the latter can be disengaged.
Fig. 4 is identical with Fig. 3 except that the pressed out locking or snap
projection C 2 is on the same side of the elbow as the flexible arm C.
In Fig. 5 there is no spring elbow. The arm C has a projection C' which enters
a recess in the socket D the arm being kept in position by a tapered cottar H
driven down so as to wedge the tail of the arm C in position.
In Fig. 6 there is a spring tongue D' stamped out of the material of the socket D*
and having a ridge at the back which engages with a vane or crook C³ on the tail
of the arm C. By pushing down the tail of the arm C into the socket d'
it snaps behind the spring d' and by lifting the spring & the tail can be released
again.
In Fig. 7 the socket D' has beneath it a pressed out tooth or stop De which
enters the loop of the elbow at the foot of the arm C. The free end of the elbow
has an inclined termination which acts as a wedging spring to draw up and hold the
elbow against the tooth or stop D°.
In Fig. 8 the socket D itself is formed as a spring eye to nip and hold the
flexible arm C. The foot of the arm C is formed with an eye engaging with a
tooth or stop D'.
In Fig. 9 the same formation of spring socket is used the foot of the arm C has
a portion bent at right angles which snaps into a hole in the arm beneath the
socket.
In Fig. 10 the foot of the arm C has a pressed projection or knee C 2 which
snaps into a recess made to receive it in the spring socket D'.
In Fig. 11 the crooked foot of the arm C is held in position by a cover D'
which is slid over the arm D' after the part C bas been placed in position. The
arm D' might either be flat across as shown in the lower plan view or it might
be recessed to receive the foot of the flexible arm C as shown in the plan
Fig. 114.
In Fig. 12 the flexible arm C is held to the side of the ferrule arm D¹ by a
sliding jamb ring D'.
In Fig. 13 the cover D 7 is hinged to the arm D¹ so as to turn over the arm C
and secure it.
In Fig. 14 the foot of the flexible arm C is made with a spring loop or eye which
engages with the suitably shaped arm D¹.
In Fig. 15 the spiral or corkscrew formed foot of the flexible arm C is dropped
into the socket D₁ and held by a projecting finger engaging in a notch while in
Fig. 16 the similarly spiral shaped foot of the arm C fits upon the cylindrical
projection from the arm D' and is held by a finger projecting inwards and engaging
in a notch. In all of these different forms the flexible arm C is readily attachable
to and detachable from the arm D₁ so that if the flexible arm C should at any time
be disabled or broken it can easily and speedily be removed and replaced by a
fresh arm without disturbing the ferrule. Although we have shown so many forms
of this improved detachable connection between the ferrule arm and the whip

page_text: traveller we do not of course confine ourselves to these and consider any ready
means of attaching and detaching the whip traveller as within the scope of our
invention.
Our invention also relates to improved means for enabling the ferrule D to be
anore easily applied when the fingers D³ have been bent to the proper angle and
shape. When using a socket ring such as E, E' shown in Fig. 1 it is essential to
have the confining race as much in diameter as possible so as to diminish the
frictional resistance or drag upon the said fingers. In former cases for example in
the aforesaid former Specification of Richard Todd No. 20487 of 1894 it was
necessary to introduce the fingers first into the race and then to bend them outwards
at right angles to the ferrule. This was an operation which took considerable time
and care and interfered materially with the economical use of the invention. Under
our present invention the fingers can be properly bent and shaped before being
placed in the race of the socket ring. To effect this we so cut out or form the
ferrule that it becomes possible and easy to slip the bent fingers of the ferrule into
working position in the race. This new mode of forming the ferrule is shown in
Figs. 17 to 20 Sheet 2. We cut out or shape the sides of the ferrule D opposite
to the fingers D'. When this is done the fingers D³ can be inserted into the race
the cut out sides of the ferrule allowing it to be canted in the manner shown at
Fig. 20 thereby permitting of the introduction of the fingers D³ into the race. The
spindle A may then be passed upwards or downwards through the ferrule and
socket ring. Not only does this cutting out of the ferrule enable the bent fingers D³
to be introduced into the socket ring race, but it has also the advantage of greatly
lightening the ferrule and reducing frictional drag. Another method of introducing
the already bent fingers D³ of the ferrule into the race is to render the arms D'D
detachable from the ferrule D. This improvement is illustrated in Figs. 21 and 22.
Fig. 21 is a vertical section of the ferrule and separately applied arms and Fig. 22
is an exterior view of the ferrule without the arms but with the upper half or cap
of the socket ring shown surrounding the ferrule. The ferrule D is formed with
its fingers D³ bent to the proper shape and set. The ferrule is also formed with
side snap springs d pressed out of the material. The arms D¹ D' are formed in
one piece with a ring De from which the arms spring. The ring D³ is formed with
perforations to receive projections d' from the springs d. In applying the ferrule
we place the fingers D³ on the race of the lower half of the socket ring, then place
the upper half of the socket ring in position, slipping it over the ferrule and then
snap the ring D³ carrying the arms upon the upper spring portion of the ferrule.
Figs. 23 and 24 illustrate improved means for introducing and holding down the
caps E' of the socket rings E. We effect this by means of clips J secured to the
lifting rail F by screws K. This enables us to dispense with threading the cap
and socket to screw them together as in the said prior specification of Todd, or the
provision of screwed studs to connect the ring aud cap. It is advisable to provide
that the cap E' shall be capable of being passed down into position through the
curbing sleeve G therefore we seek to reduce its diameter as much as possible.
In Fig. 23 a ledge E is formed in the interior of the socket ring E, this ledge
receiving and supporting the outer edge of the cap E¹. The clips J extending
over the cap and ring hold the cap in position. As the dotted lines show, the cap
is sufficiently small to pass through the curbing sleeve G. In Fig. 24 a separate
annular cover plate or ring L is seated in a check or recess in the socket ring E
and the cap E¹ is placed over this annular ring L the clips J holding both ring
and cap in position. In this instance also as the dotted lines show the cap can be
passed through the curbing ring G. The annular cover plate or ring L may be
made in two halves.
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 spinning apparatus of the indicated nature and construction making the

page_text: flexible arm or whip traveller such as C readily attachable to and detachable from
the ferrule.
2. In spinning apparatus of the indicated nature and construction making the
flexible arm or whip traveller C readily attachable to and detachable from the
ferrule by any suitable means and particularly by the various methods hereinbefore
described and illustrated in Figs. 2 to 16 Sheet 1 of the drawings.
3. Forming or constructing the ferrule D in such a manner that the bent
fingers D³ at the foot of the ferrule can be introduced into the race between the
socket ring E and its cover E¹ the said improved formation consisting in cutting
out or recessing the sides of the ferrule in the manner illustrated in Figs. 17 to 20
Sheet 2 of the drawings or by rendering the arms D¹ D' detachable from the
ferrule as shown in Figs. 21 and 22 Sheet 2.
4. The improved construction of socket ring for enabling the cap E' to be
passed down through the curbing sleeve G together with the means for holding
the socket rings down in the rail substantially as described and as illustrated in.
