Improvements in or Applicable to Ring Doubling and Twisting
Machines.
We, HENRY BIRKBY ARUNDEL, of Bromley Street Works, Manchester, in the
County of Lancaster, Machine Maker, and WILLIAM BROCKLEBANK of 84 Bradford
Road, Manchester aforesaid, Overlooker do hereby declare the nature of the said
invention to be as follows:-
Our invention relates to ring doubling and twisting machines, and its object is to
provide against the consequences of excessive ballooning in any particular threads
arising from various causes and producing damage to and defects in the threads being
doubled and twisted.
Our invention consists in arranging a fixed rail (wood by preference) from end to
end of each side of the doubling and twisting frame, and then inserting in such rail a
projecting wire for each spindle this wire being placed in an oblique position in
relation to the spindle and having a hook slit formed in it.
The hook end of the wire which projects from the rail, is at a level, just above the
head of the bobbin on the spindle and will be clear of the thread between the traveller
on the ring and the guide wire when properly working with the ordinary amount of
ballooning but when excessive ballooning occurs say from the breaking of a travellor,
or lumps getting upon the thread and obstructing or other cause, the thread will catch
upon the hook of the projecting wire, and break the thread and thus prevent defective
thread from being wound upon the bobbin, and damage and waste by lapping or
lashing against and becoming entangled with adjoining threads.

We, HENRY BIRKBY ARUNDEL, of Bromley Street Works, Manchester, in the
County of Lancaster, Machine Maker, and WILLIAM BROCKLEBANK of 84 Bradford
Road, Manchester, aforesaid, Overlooker do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to ring doubling and twisting machines, and its object is to
provide against the consequences of excessive ballooning in any particular threads,
arising from various causes and producing damage to and defects in the threads
being doubled and twisted.
Our invention consists in arranging a fixed rail, (wood by preference) from end to
end of each side of the doubling and twisting frame and then inserting in such rail a
projecting wire for each spindle, this wire being placed in an oblique position in
relation to the spindle, and having a hook slit formed in it.
The hook end of the wire which projects from the rail, is at a level, just above the
head of the bobbin on the spindle and will be clear of the thread between the
"traveller " on the "ring" and the guide wire when properly working with the
ordinary amount of ballooning, but when excessive ballooning occurs say from the
breaking of a traveller, or lumps getting upon the thread and obstructing or other
cause, the thread will catch upon and will be broken by the hook of the projecting
wire, and this will prevent defective thread from being wound upon the bobbin, and
damage and waste by lapping or lashing against and becoming entangled with
adjoining threads,
Fig. 1 is a partial cross sectional elevation of a ring doubling frame.
a represents part of the roller beam, 6 thread guide wire board, 6' thread guide wires,
62 glass rod over which the threads pass, c the spools or bobbins which are carried
upon the twisting spindles, not shown, e ring rail, e¹ ring, e³ traveller, the thread
between the traveller and guide wire b¹.
All the above parts indicated by reference letters, are ordinary parts of doublers
and twisters. d is a straight piece of wire with a slit d' cut in it to form a hook, the
slit being on the underside as shown.-One of these wires d is used opposite each
spindle, they are driven into a rail & formed of wood by preference, each wire
extending to the same extent from the rail d' which is carried on brackets d' which
are attached at intervals to the roller beam a or other convenient stationary part of
the machine.
The rail is secured so that the wires d are in an oblique position in relation to
the spindle or bobbin with the ends of the wires just a little above the level of the
upper end of the bobbin c as shown, and clear of the thread x, when there is only the
ordinary amount of ballooning.

page_text: The rail is adjustable to bring the ends of the wires d in it to the required
position, when it is then secured.
The wires are not in the way when doffing; but will catch the thread when from
any cause there is an excess of ballooning and break it, and will frequently catch a
thread when broken.
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 wo
claim is.
The combination of a catch wire (d) placed in an oblique position each wire having
a slit (d) and being carried in a rail (d) with the spindle of doubling and twisting
machines, so arranged that the outer end of the wire (d) will be clear of the thread (x)
when there is only the normal amount of ballooning, but which wire will catch the
thread, when there is an excess of ballooning as hereinbefore described and illustrated
by the drawing.
