We, GEORGE HENRY THOMSON and WILLIAM THOMSON, both of Wellfield Works,
Fletcher Street, Rochdale, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention is applicable to such ring-spinning and doubling frames as have
a straight up-and-down traverse of the ring-rail and wind the yarn onto spools
or bobbins and the object of the invention is to prevent the ballooning" of the
yarns or threads especially during that part of the "lift" when the yarn is being
wound onto the lower portion of the spool or bobbin.
For this purpose we have a longitudinal rail mounted on pivots carried in
brackets about midway of the "lift" or rather higher, the rail being provided
with a series of fingers extending forwards between the spindles.
The pivots of this rail are placed near to the back edge thereof so that the
weight of the rail and fingers will always have a tendency to press the fingers
downwards, but they are prevented from falling below the horizontal position, or
thereabouts, by means of stops attached to the brackets, or to the rail.
As the ring-rail rises, as soon as it arrives at about the centre of its lift it comes
under the fingers and raises them up with it into a diagonal position, and as the
ring rail falls, as soon as it reaches the centre, or nearly so, the stops above referred
to come into action and prevent the fingers from falling any lower and as they
remain in a horizontal position during the rest of the traverse they effectually
prevent any ballooning" of the yarn.
Before loffing the attendant raises the fingers and throws the rail back
on its pivots out of the way, and when a fresh set of spools or bobbins has been
placed on the spindles he moves the rail back into its original position with the
fingers projecting outwards between the spindles.

Improvements applicable to Ring-spinning and Doubling Frames.
We, GEORGE HENRY THOMSON and WILLIAM THOMSON, both of Wellfield Works,
Fletcher Street, Rochdale, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention and in what manner the same is to be per-
[Price 8d.]

page_text: formed, to be particularly described and ascertained in and by the following
statement: -
This invention is applicable to such ring-spinning and doubling frames as have
a straight up-and-down traverse of the ring-rail and wind the yarn onto spools
or bobbins, and the object of the invention is to prevent the "ballooning" of the
yarns or threads especially during that part of the "lift" when the yarn is being
wound onto the lower portion of the spool or bobbin.
The manner in which our said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a front elevation and Fig. 2 a plan view of our
improved anti-ballooning finger rail and Fig. 3 shows the application thereof to
a ring-spinning frame being part of the frame, the ring-rail, e the spindle rail
and d one of the spools or bobbins.
For the purposes of our invention we have a longitudinal rail e mounted on
pivots e carried in brackets f about midway of the "lift" or rather higher,
the raile being provided with a series of fingers y extending forwards between
the spindles.
The pivots e of this rail e are placed either centrally or near to the back edge
thereof so that the weight of the rail e and fingers g will always have a tendency to
press the fingers g downwards (see Fig. 3) but they are prevented from falling below
the horizontal position, or thereabouts, by means of stops f* attached to the brackets f
(see Figs. 1 and 3,) or to the rail e.
As the ring rail b rises, as soon as it arrives at about the centre of its lift it
comes under the fingers g and raises them up with it into a diagonal position, and
as the ring rail falls, as soon as it reaches the centre, or nearly so (see Fig. 3)
the stops above referred to come into action and prevent the fingers from fall-
ing any lower and as they remain in a horizontal position during the rest of the
traverse they effectually prevent any "ballooning" of the yarn.
Before doff ng the attendant raises the fingers g and throws the rail e back on
its pivots e* out of the way and when a fresh set of spools or bobbins & has been
placed on the spindles he moves the rail e back into its original position with the
fingers g projecting outwards between the spindles.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The improvements applicable to ring-spinning and doubling frames having a
straight up-and-down traverse of the ring-rail consisting in the application thereto
of a straight rail provided with fingers projecting horizontally above the ring-
rail between the spools, such rail being mounted on brackets provided with stops
which prevent the fingers from falling below the horizontal position but which
allow of their being thrown over backwards by hand out of the way for doffing
the spools, and replaced in the same manner ready for action when commencing
a fresh set of spools or bobbins.
