Improvements in Means or Apparatus employed in Winding,
Twisting, or "Doubling" Yarn or Thread.
We PRINCE SMITH, of the firm of Prince Smith & Son, of Burlington Shed,
Keighley, in the County of York, Machine Maker, and SMITH AMBLER, of the
same place, and in the employ of the said firm, Draughtsman, do hereby declare the
nature of this invention to be as follows:-
The present invention is designed to simplify and improve the construction, arrange-
ment, or combination and use of parts of apparatus, employed in winding, twisting,
or doubling yarn, or thread, to prevent the formation of imperfect work, such as is
known as "singles," or "single" yarn, "double knots," or other defective results
and to facilitate piecing up.
According to our present invention, as arranged in one form, the main framing is
adapted to carry the supports for the series of bobbins, cops, or holders, and the
machine for convenience is duplicated and driven from a central driving shaft and
pulley.
The yarn, or thread, passes from these bobbins, cops, or holders to a series of
detectors, one detector to each yarn, or thread, and which when all is in work and
tension is on the particular thread, the detector allotted to it is kept raised and
idle; thence the thread passes on through a guide to and partly around one and
then another of a pair (or other number) of friction driven rollers and in operation
the lower top friction roller presses on the feed roller and the thread between them
is drawn and fed forward to and passes through the eye of a jointed lever hinged on
a centre, carried by a bracket, or support, from the framing so that its end opposite
to the thread eye which carries a small hinged lock, or obstacle, may be capable
of swinging this block into and out of engagement with parts to be described. The
thread thence passes to the caps or tubes, ring spindles or flyers so as to be wound,
doubled, or twisted, and these latter parts are driven hy bands from the driving
pulley on which are formed risers, or projections, which act to throw off the driving
band from such pulley onto a side surface, preferably formed as a part circle, with a
gap in the continuity of its periphery to admit of easier removal and replacement
without disturbance of the driving shaft and this ring or part circle acts as a
frictional break, it being stationary, to stop the band and thereby the twisting
of the spindle, or the like.
Adjacent to the block on the swing arm referred to is a rotating cam, or
striker, which on occasion strikes this block when it becomes interposed in its
path of rotation and this will take place should the thread fail to keep down, or
in place, the eye end of the swing lever and so let the opposite end tilt the
block into the said contact. Then the block being struck it moves and in moving
out of the course of the cam it presses back, or away, one part of a hinged arm,
hinged on a bracket, or support, from the framing, about its middle, the other
part of this arm being formed with a snick, or notch and an incline, the function
of which notch is to engage a projection on and hold up or in operative position
and the incline to guide it, the hinged lever which by its one portion carries the
bearings for the journals of the top rollers so as to be frictionally driven by
the feed roller; or when such projection is released to allow those rollers with
it to tilt out of driving contact therewith and so stay the supply of thread.
As this lever tilts its opposite end draws, or moves,, a rod connected to it and
to a cranked arm with fingers, also thereby moved and thereby the driving band
is moved on one side of its direct operative path and into the path of the pro-
jections on the driving pulley and by these it is as already mentioned thrown
around the break ring and stopped.

page_text: The detectors on the threads between the supply and the feed roller are
preferably formed as thin strips, having a slightly formed twist to receive the
thread and thereby hang suspended on it (as long as it is intact) whilst at each
of their lower ends these strips are formed with holes by which they are passed
on to pins projecting from series of weighted rock arms centred on a fin or shell
from the balance arm of the catch, or notch lever and these detector blades we
prefer to guide in slots formed in a plate adapted for convenience of adjustment
to slide on the upper part of this arm, and be secured by screwing. These
weighted rock arins and the detectors attached when in their dropped position
rest on a rod across the balance end of the notch lever and this rod serves for
the block to press on: Another rod serves to determine the extent of move-
ment upward of the detectors by engaging the balance ends of the rock arms
thereof.
The break surfaces, or part rings we prefer to support adjustably by means
of lugs, arms, or projections oppositely disposed and bolted or otherwise secured
to bars or supports which may be secured lengthwise of the machine conveniently
for the purpose.
Upon the front of the lever which carries the top rollers we apply a handle
part so that the operator may reinstate the parts as soon as any default has
been made good and by lifting that lever end engage the trigger parts by
causing the catch to enter the notch at the same time setting the driving band
in operating position, the tension of the respective threads depressing the eye
levers and lifting the detectors free of the blocks. Rearwardly the said top
roller lever is formed with projecting or stop part to determine the extent of
movement of the end of the lever on which the block is hung and in certain
movements carry it with it.
We have mainly described the invention with reference to one set only of a
number of co-operative parts as thereby simplicity of description is promoted
the other parts being either mainly as usual or duplications of those described.

disposition to adapt the frame to the particular operation to be performed or the
quality of the work may be made without departing from the essential features
of novelty of the invention.

Improvements in Means or Apparatus employed in Winding,
Twisting, or "Doubling" Yarn or Thread.
We PRINCE SMITH of the firm of Prince Smith & Son, of Burlington Shed
Keighley, in the County of York, Machine Maker, and SMITH AMBLER, of the
same place, and in the employment of the said firm, Draughtsman, 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 present invention is designed to simplify and improve the construction
arrangement, or combination and use of parts of apparatus, employed in winding,
twisting, or doubling yarn, or thread, to prevent the formation of imperfect
work, such as is known as "singles," or "single" yarn, "double knots," or other
defective results and to facilitate piecing up..
According to our present invention, as arranged in one form shewn by the
accompanying drawings, the main framing A is adapted to carry the supports B
for the series of bobbins, cops, or thread holders B' and the. machine for con-
venience is duplicated (although in the drawing Fig. 1 the parts to the left hand

Fig. 5 is a side view and Fig. 6 is a plan view of the driving bands and the
pulleys driving them and the side friction surface which replaces the ordinary
loose pulley.
Fig. 7 is a side view aud Fig. 8 is a front view of this friction surface 1.
Fig. 9 is a side view and Fig. 10 is a like view of the support o for the upper
rollers and one of the levers a respectively.
Fig. 11 is an edge view and Fig. 12 is a side view of one of the detectors
separately to an enlarged scale.
Fig. 13 shews by an edge view and Fig. 14 by a side view, one of the
weighted rock arms on to the pin r' of which one of the detectors is hinged.
The yarn, or thread, passes from these bobbins, cops, or holders of which four
are shewn to a series of detectors, one detector e to each yarn, or thread d and
when all is in work and tension is on the particular thread d, the detector c allotted
to it is kept raised and idle; thence the thread passes on through a guide e to and
partly around one and then another of a pair (or other number) of friction driven
rollers and and in operation the lower top friction roller g presses on the feed
roller and the thread between them is drawn and fed forward to and passes
through the eye of a jointed lever (being a joint therein) hinged on a
centre, carried by a bracket or support, from the framing A so that its end i
opposite to the thread which carries a small hinged block is, or obstacle, may be
capable of swinging this block into and out of engagement with parts to be
described. The combined yarns or thread d thence passes to the caps or tubes or
ring spindles or flyers (here shewn as a cap, and spindle j) so as to be wound,
doubled, or twisted, and these latter parts are driven by one of a series of bands
from the driving pulley on which are formed rises, or projections which act in
conjunction with the fingers to throw off the driving band k from such pulley b
onto a side surface preferably formed as a part circle with a gap in the
continuity of its periphery to admit of easier removal and replacement without
disturbance of the driving shaft a and this ring or part circle acts as a frictional
break, it being stationary, to stop the band and thereby the twisting of the
spindle, or the like receiver for the combined thread.
Adjacent to the block on the swing arm i referred to is a rotating cam, or
striker m, which on occasion strikes this block when it becomes interposed in the
path of its rotation and this will take place should the thread fail to keep down,
or in place, the eye end of the swing lever i and so let the opposite end
the block into the said contact.
tilt
Then the block being struck it moves and in moving out of the course of the
cam it presses back, or away, one part n' of a hinged arm n, hinged at C' on a
bracket or support C from the framing A about its middle, the other part n² of
this arm n being formed with a snick n³, or notch and an incline n', the function
of which notch n is to engage a projection o on the lever o and hold up or in
operative position the hinged lever o which by its one portion of carries the
bearings for the journals of the top rollers ƒ and g so as to be frictionally driven
by the feed roller or when such projection is released to allow those rollers f
9 with it to tilt out of driving contact therewith (as indicated by the dotted
lines Fig. 2) and so stay the supply of thread.
and
The incline n serves to aid the notch n³ and projection o² to correctly engage.
As this lever o tilts on its centre of its opposite end of draws, or moves, a rod p

page_text: connected to it and to a cranked arm 9 provided with fingers or guides q¹ also
thereby moved and thereby the driving band k is moved on one side of its direct
operative path and into the path of the projections on the driving pulley b
and by these it is as already mentioned thrown around the break ring and
stopped.
3.1
The detectors c on the threads d between the supply holders B¹ and the feed
roller are preferably formed as thin strips, having a slightly formed twist c
(shewn separately and to a larger scale Figs. 11 and 12) to receive the thread
and thereby hang suspended on it (as long as it is intact) whilst at each of their
lower ends these strips are formed with holes by which they are passed onto
pins projecting from series of weighted rock arms centred on a pin or shell n'
from the balance arm of the catch, or notch lever n and these detector blades we
prefer to guide in slots ne formed in a plate n' adapted for convenience of adjust-
ment to slide on the upper part of this arm n, and he secured by screwing at n.
These weighted rock arms and the detectors c attached, when in their dropped
position rest on a rod n³ across the balance end n' of the notch lever n and this
rod serves for the block to press on. Another rod n³ serves to determine the
extent of movement upward of the detectors c by engaging the balance ends „ª of
the rock arms thereof.
The break surfaces, or part rings we prefer to support adjustably by means
of lugs, arms or projections oppositely disposed and bolted or otherwise secured
to bars or supports s which may be secured lengthwise of the machine conveniently
for the purpose.
Upon the front of the lever o which carries the top rollers ƒ and g we apply a
handle part o so that the operator may reinstate the parts as soon as any default
has been made good and by lifting that lever end o¹ engage the trigger parts o
and n by causing the catch o² to enter the notch at the same time setting the
driving band & in operating position, the tension of the respective threads depressing
the eye levers and lifting the detectors c free of the blocks. Rearwardly the
said top roller lever o¹ is formed with a projecting or stop part of adapted to
determine the extent of movement of the end of the lever i on which the block i
is hung and in certain movements carry it with it.
We have mainly described the invention with reference to one set only of a
number of cooperative parts as thereby simplicity of description is promoted the
other parts being either mainly as usual or duplications of those described.
Various modifications in details or number of individual parts or their relative
disposition to adapt the frame, to the particular operation to be performed or the
quality of the work, may be made without departing from the essential features of
novelty of the invention.
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. A detector mechanism actuated by the breaking of the thread after it has
passed the rollers consisting of the thread guide lever i which carries a hanging
block at its end opposite to the thread guide operating substantially as described.
2. A detector mechanism actuated by the breaking of a strand before passing
the rollers consisting of a hinged arm n, carrying detectors and rock arms and
retaining the rollers in position by a catch at the bottom of an inclined edge all
operating substantially as described.
3. A double detector mechanism consisting of the detector mechanisms respec-
tively claimed in the first and second claims hereof combined and operating
substantially as described.
4. A pivotted lever o supporting the drawing rollers and bearing the catch o
and the stop of operating as and for the purposes described.
5. In a double detector mechanism the use of a stop o' on the lever supporting

page_text: the rollers for holding the front detector mechanism clear of the moving machinery
when the detector mechanism is actuated by the breaking of a thread or a strand,
substantially as described.
6. The method of operating detector mechanism by means of detectors connected
to and rendered operative by rock arms r, substantially as described.
7. The combination of parts for putting the driving bands into and out of the
driving position substantially as described with reference to Figures 5 and 6.
8. The general combination and arrangement of parts described and shewn in
Figures 1 and 2.
