I JAMES DICKINSON of Prestwich near Manchester in the County of Lancaster
Engineer do hereby declare the nature of this invention to be as follows:-
وو
The object of this invention is to prevent what is known as "ballooning on ring
frames especially when spinning or doubling upon bobbins more than about five
inches in length.
It is well known to persons conversant with spinning and doubling upon ring
frames that when a longer bobbin than about five inches is attempted to be use on
such frames especially during the winding of the first portion of the cop it is very
difficult to prevent the yarn from flying out in a curve (or "ballooning" as it is
termed) owing to the great distance between the guide wires and the ring and
traveller when winding on the lower portion of the bobbin, and the threads are then
very liable to become entangled and broken, and special means have to be provided,
which are more or less complicated and expensive, and hence a great portion of the
advantage of using bobbins of a greater length is counterbalanced by the increased
cost of the machine.
And on the other hand if the guide wires are fixed close above the top of the
bobbins, when winding on the upper portion of the bobbin the yarn runs off at too
acute an angle and is hence liable to become broken, especially when spinning or
doubling fine counts of yarn.
According to my invention I mount the guide wire flaps on a long metal rod
placed in such a position that when they are in their normal position the guide wires
are held sloping slightly downwards and with their ends about three eighths of an
inch above the tops of the bobbins and they are allowed to remain in this position
until about one third or one half of the cop has been wound so that the distance
between the guide wire and the ring-and-traveller is maintained at a minimum, and
"ballooning" prevented.
I make the guide wire flaps of wood and screw the guide wires therein, and to the
underside of the wood I fix by screws a metal plate which is bent up into a curl at
the back of the wood; and, the long metal rod passing through it, this curl serves
as a hinge to the guide flaps.
The centre part of the curl is slotted and, a pin passing through the slot is fixed
in the rod so as to allow any of the flaps to be turned up for "doffing" or "piecing-
up" without moving the rod, and at the same time by turning the rod in its bearings
all the guide wires can be raised or lowered at once.
As soon as the cops have been about one half wound on, the attendant partially
turns the long metal rod so as to raise all the guide wires till their ends are the
same distance above the horizontal line as they were originally below it when they
will of course be in the same vertical position with regard to the centre of the
bobbin but about an inch and a half higher.
By thus raising the guide wires above the top of the bobbins during the time of
winding-on the upper portion of the bobbins, the yarn is not caused to run off at
such an acute angle as heretofore and is not so liable to become broken, and hence
the two defects above mentioned are remedied and the yarn can be wound on bobbins,
of six inches length without "ballooning" and with fewer breakages than hitherto.
Instead of the attendant having to give the partial turn to the long rod so as to
raise the guide wires at the required time I propose in some cases to connect a

made automatically at the proper time.

An Improvement Applicable to Ring Throstle Frames and Ring
Doubling Frames used for Spinning and Doubling Cotton and
other Fibrous Substances.
I JAMES DICKINSON of Prestwich near Manchester in the County of Lancaster
Engineer 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 :-

The object of this invention is to prevent what is known as ballooning" on
ring frames especially when spinning or doubling upon bobbins more than about
five inches in length.
It is well known to persons conversant with spinning and doubling upon ring
frames that when a longer bobbin than about five inches is attempted to be used on
such frames especially during the winding of the first portion of the cop it is very
difficult to prevent the yarn from flying out in a curve (or "ballooning" as it is
termed, owing to the great distance between the guide wires and the ring and
traveller when winding on the lower portion of the bobbin; and the threads are
then very liable to become entangled and broken; and special means have to be
provided, which are more or less complicated and expensive, and hence a great
portion of the advantage of using bobbins of a greater length is counterbalanced
by the increased cost of the machine.
And on the other hand if the guide wires are fixed close above the top of the
bobbins, when winding on the upper portion of the bobbin the yarn runs off at
too acute an angle and is hence liable to become broken, especially when spinning
or doubling fine counts of yarn.
"
"
The nature of my said invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference to
the two sheets of drawings hereunto annexed and the following explanation thereof.
Fig. 1 (on Sheet 1. of the drawings) is a vertical section of so much of a ring frame
as is necessary to illustrate the application of my invention thereto, the guide wires
being drawn in the position which (according to my invention) they assume at the
commencement of the winding on of a set of cops.
Fig. 2. is a front elevation and Fig. 3. a vertical section, showing the position of
the guide wires when the cops are approaching completion.
Fig. 4 is a section and plan of one of the guide wire flaps or lappets drawn full
size so as to show the details of construction.
Fig. 5 is a diagram hereinafter referred to, and Fig. 6 (sheet 2) is a section
showing a modified form of my said invention; and Fig. 7 is a section showing an
automatic arrangement applied to the apparatus shown at Fig. 1.
a is the spindle rail, 6 the ring rail and c the roller beam, d are the spools e the
guide wire flaps or lappets and the guide wires.
According to my invention I mount the guide wire flaps e on a long metal rod g
so arranged that when they are in their position for commencing a set of cops as
shown at Fig. 1. the guide wires fare held sloping slightly downwards and with
their ends about three eighths of an inch above the tops of the bobbins d and they
are allowed to remain in this position until about one third or one half of the cop
has been wound so that the distance between the guide wire f and the ring-and-
traveller is maintained at a minimum, and "ballooning" prevented.

page_text: I make the guide wire flapse of wood and screw the guide wires therein (see Fig. 4).
and to the underside of the wood I fix by screws h a metal plate i which is bent up
into a curl at the back of the wood e, and the long metal rod 9 passing through it,.
this curl serves as a hinge to the guide flaps e.
The centre part of the curl is slotted as at Fig. 4. and a pin or screw 7 passing
through the slot k is fixed in the rod g so as to allow any of the flaps e to be turned.
up for piecing up as shown by dotted at Fig. 1. without moving the rod g and at
the same time by turning the said rod in its bearings all the flaps e and guide wires f
can be raised or lowered at once for doffing.
As soon as the cops have been about one half wound on, the attendant partially
turns the long metal rod g by means of the handle m so as to raise all the guide
wires till their ends are the same distance above the horizontal line as they were
originally below it when they will of course be in the same vertical position with
regard to the centre of the bobbin but about an inch and a half higher.
The extreme positions of the guide wires (at commencement and finish of the
spinning) are illustrated by the points 1 and 2 on the diagram Fig. 5. which shows-
that in either position the eye of the guide is vertical above the top of the spindle.
By thus raising the guide wires f above the top of the bobbins d during the time-
of winding-on the upper portion of the bobbins, the yarn is not caused to run off at
such an acute angle as heretofore, and is not so liable to become broken, and hence
the two defects above mentioned are remedied, and the yarn can be wound on
bobbins of six inches length without "ballooning" and with fewer breakages than
hitherto ;
m is a peg which holds the handle m in the required position by being
passed into either of the holes in the bracket m¹¹.
Instead of the attendant having to give the partial turn to the long rod g so as to
raise the guide wires at the required time I propose in some cases to connect a lever
or handle m fixed on this rod with a cain or tappet actuated by any convenient.
moving part of the machine in such a way as to cause this change of position to be
made automatically at the proper time.
Or instead of the above I may use the arrangement shown at Fig. 7. which is a
simple automatic means for raising the guide wire flaps or lappets at the proper
time, tho handle m is in this case dispensed with and at or near the end of the rod, g
I fix a quadrant p over which hangs a weighted strap q. This quadrant is provided
with a lever or tail piece r having a projection at its lower end by which it is
held in the position shown by means of a catch lever s.
As soon as the ring rail bin its traverse (as the cop is built up) rises to a certain
height it comes against and raises the catch lever s thus releasing the tail piece and
allowing the weighted strap 9 to pull over the quadrant until the projection t comes
against a catch which will then hold the guide wire flaps or lappets in the position
shown by dotted lines.
When it is required to raise all the lappets for doffing, the catch u must be lifted by
hand and the weighted strap will then lift them sufficiently high to allow of doffing.
Fig. 6 (sheet 2) shows a modification whereby the same effect may be obtained
without the use of the long rod g.
In this case I substitute for the rod g a long bar g' of wood to which all the guide
wire flaps
e are hinged at g¹ and this bar g' is in its turn hinged at n to the
front of the roller beam c.
Any convenient attachment (such for instance as that shown at o) is fitted to the
long bar g¹ whereby it can be raised up on its hingen (as shown by the dotted
lines). The hinge at g¹ allows of any of the flaps e being turned up singly when
required.
To the attachment o or bar o¹ is connected the other end of this bar being secured
to one end of a short lever o" by a pin. On this same pin is mounted a draw bar ol
provided with three notches and passing through a slot in the roller beam c. When
the draw bar is on the first notch as shown the lappets e will be held in their lowest
position. The second notch is for the next position as shown in dotted lines and the
third notch will raise them into the proper position for doffing.

page_text: 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
First. So mounting the guide wire flaps or lappets of ring spinning or doubling
frames that they can be brought down below the horizontal position to within a very
short distance from the tops of the spools when commencing a fresh set of cops, and
then raised up above the horizontal position (either by hand or automatically) as the
winding-on proceeds for the purpose herein before set forth and substantially as
described and illustrated by Figs. 1, 2, 3, 5, 6 and 7 of the drawings hereto annexed.
Secondly. I claim the particular construction of the guide wire flaps and their
adjuncts as described with reference to Fig. 4 on the drawings.
Thirdly. I claim the modification of my invention substantially as shown and
described with reference to Fig. 6. and
Fourthly. I claim the general combination and arrangements of parts substantially
as and for the purpose hereinbefore set forth and illustrated by the drawings
annexed.
