Improvements in Thread Guides applicable for use in connection
with Machines for Twisting, Winding, and Reeling Fibrous
Substances, or for like Operations.
We, THOMAS SLINGSBY of the firm of Ira Ickringill and Company Limited, of
Keighley in the County of York, Spinners, and JOSEPH WHITFIELD of the same
place, Manager, do hereby declare the nature of this invention to be as
follows, that is to say :-
In machines for twisting as well as in those for winding and reeling threads
of fibrous substances, the thread guides heretofore employed have always,
either in one part or another, presented a stationary surface over which, the
said threads have had to pass when stretched and moving from one part to another,
and by reason of the continued rubbing or friction of these threads on the said
stationary surfaces, the latter have rapidly deteriorated by reason of being worn
into slits as is well known.
To obviate this defect in connection with the means for guiding the threads in
twisting machines we mount guide rollers in such relative positions with the draw-
drums or trap rollers and the bobbins on said machines, that said threads are
throughout their entire passage from one of the said parts to the other, never
allowed to come into contact with any stationary or fixed guiding surface.
To enable the threads to maintain their relative positions when passing around
the draw-drum we mount and make to extend, our guide roller in such a position
relatively with this draw-drum that said positions of the threads thereon are not
interfered with, but by the said guide roller being of sufficient length and
preferably placed about parallel with said draw-drum so as to allow any vertical
movement of said threads, any position they may assume on said draw-drum does
not detract from the efficiency of said guide roller.
To maintain the proper course of the thread after it leaves the above described
guide roller so that it may continue its course on to the outer end of the trap lever,
we mount another guide roller in a somewhat horizontal position, and the supports
for this guide roller as also for the one above described are so formed that one side
of it or each of them is perfectly open or uncovered in order that the thread while
still stretched might be readily brought into contact therewith.
We also mount a guide roller in the outer end of the trap lever although in an
ordinary way a roller at this part is not necessary.
Under certain conditions we also mount guide rollers upon the well known form
of guide-piece employed for conducting the single untwisted threads on to the draw-
drums or trap-rollers, and we do this in such a manner as to leave each thread a
clear course in one direction laterally so that any necessary repairs thereto may be
freely effected by the operative. Whenever these single threads are found to be
too weak to interfere with any stationary surface in any degree so as to wear it into
slits we then dispense with these rollers and use the guide-piece without them in
combination with our other parts.
In connection with machines for winding and reeling said threads of yarn,
wherein it is necessary from time to time to change the paths in which said threads
are travelling thus necessitating guides that will press upon both sides, that is to
the left and right of each, of them, we mount two rollers in suitable bearings so
that they may be in suitable proximity with each other. These bearings are
arranged so that a slit or opening for the passage of the stretched thread is
provided, either near one or other or both of their extremities, and we preferably
form such opening so as to be at an angle to the direction in which the thread

page_text: travels in its passage between the rollers in order that although it thus to be
brought by the operative to pass between the rollers it is prevented during its
proper operations from becoming disarranged with its said guide rollers.

place, 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, that is to say :-

The sheets of drawings hereunto appended are illustrative of our invention and
reference by figures and letters is made to them in the following description.
Fig. 1 is sectional end elevation of a portion of a machine known as a
twister," most of the framework being omitted in order that the several parts
forming the subject matter of our invention might be more clearly seen.
Fig. 2 is front elevation of parts shown by Fig. 1.
Figs. 3 and 4 are drawings in detail, enlarged scale, showing one form of the
several thread guides employed.
Figs. 6 and 7 are also drawings in detail enlarged scale, of other forms of thread
guides used in accordance with our invention.
Figs. 8, 9 and 10 are front elevations enlarged scale, showing the form of thread
guide used in connection with machines for winding and reeling threads or yarns.
Figs. 11, 12 and 13 are top views of parts shown by Figs. 8, 9 and 10
respectively.
In order to obviate the above described defect in connection with the means for
guiding the threads a in twisting machines we mount guide rollers and e in such
relative positions with the draw-drums or trap rollers d and the bobbins e on said
machines that said threads a are throughout their entire passage from the bobbins
at the back down to the bobbins e, never allowed to come into contact with any
stationary or fixed guiding surface.
To enable the threads a to maintain their relative positions when passing around
the trap-roller & we mount the roller 6 to extend vertically and otherwise be in
such a position relatively with the trap-roller d that the positions of the threads
thereon are not interfered with, but by the said guide roller b being of sufficient length
and preferably placed about parallel with said trap-roller d so as to allow any
vertical movement of said threads a, any position they may assume on said trap-
roller d does not detract from the efficiency of said guide roller b.
To maintain the proper course of the threads a after they leave the above
described roller b so that they may continue their course on to the outer end of the
trap lever f, we mount the guide roller c in a somewhat horizontal position and the

page_text: support or bearings g for this roller c as also the bearings for the roller 6 are so
formed that one side of each of these rollers b and c is perfectly open or unenclosed
in order that the threads a while still stretched might be readily brought into
contact therewith.
We also mount a guide roller k in the outer end of the trap-leverf although in
an ordinary way a roller at this part is not necessary.
Under certain conditions (as when thick and strong threads are under operation)
we also mount guide rollers m² m² m² m² and m³ upon the well known form of guide-.
piece m which is employed for conducting the single untwisted threads a on to the
trap-roller d, and we do this in the manner shewn by Figs. 3 and 4 so as to leave
each thread a an open course in one lateral direction in order that any necessary
repairs thereto may be freely effected by the operative. Whenever these single
threads a are found to be too weak to interfere with any stationary surface in any
degree so as to wear it into slits we then dispense with these rollers and use the
ordinary guide-piece without them in combination with our other parts.
In connection with machines for winding and reeling said threads of yarn,.
wherein it is necessary from time to time to change the paths in which said threads
are travelling, thus necessitating guide-pieces that will press upon both sides, that
is to the left and right of each of them, we mount two rollers p p' in appropriate
bearings s so that they may be in suitable proximity with each other. These
bearings s are arranged so that a slit or opening t for the passage of the stretched
thread is provided, either at the top of these bearings, as shown by Figs. 8.
and 10, or near the bottom of same as shown by Fig. 9, and we form
such openings t so as to be at an angle to the direction in which the thread
travels in its passage between the rollers p p¹ in order that although it thus may be
brought by the operative to pass between these rollers p p it is prevented during
its proper operations from becoming disarranged or being forced out of contact with
said rollers p p¹..
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. The arrangement and combination of guide rollers with doubling or twisting
machinery substantially as herein set forth and described.
2. The combination of the guide-rollers b and c with the trap-roller d substantially
as herein specified.
3. The combination of the guide-rollers p p¹ mounted in bearings as described
with machines or mechanism for winding or reeling yarns or threads substantially
as specified.
