PROVISIONAL SPECIFICATION.
Improvements in Thread Spooling Machines.
I WILLIAM AYRTON of Gorebrook Iron Works, Manchester, in the County
of Lancaster, Machine Maker, do hereby declare the nature of this invention to be
as follows:
My said invention relates to improvements in the construction of automatic
spooling machines of the kind described in the Patent Specification of William
Weild, No. 122 of A.D. 1858, and has for its object improved devices for actuating
the thread guides in order to ensure the parallel winding of the thread on the
bobbin.
As commonly arranged the thread guides rest immediately on the layers of
thread of the bobbin which is being wound and in this manner are gradually lifted
by the thread itself as the bobbins increase in diameter so that in the event of the
thread being unevenly wound in some of the inner layers the unevenness will be
continued through the whole bobbin and as the whole of the thread guides are
usually connected the rest of the bobbins which are being wound at the same time
will to some extent partake of the irregularity.
I
According to my said invention I provide means for raising the guides by the
positive action of mechanism instead of in the herein before described manner.
provide a sliding bar which works lengthwise of the machine and is provided with
inclined planes taking against bowls or rollers on the frame side so that as the
sliding bar travels it is gradually raised. The said sliding bar is operated by a
system of levers and adjustable links driven from a cam secured to a shaft which
makes a single revolution during the time necessary for filling a bobbin.
provide bell crank levers the horizontal or nearly horizontal arms of which bear
on the upper edge of the said sliding bar while their other arms are joined by
suitable adjustable links to swinging brackets connected with the thread guides
in such a manner that as the said sliding bar rises during its course the thread
guides are gradually lifted during the filling of the bobbin.
I
The parts are provided with adjustments in order that the rate at which the
guides are lifted may be varied to suit bobbins of varying diameters or thread of
different degrees of thickness.

COMPLETE SPECIFICATION.
Improvements in Thread Spooling Machines.
I WILLIAM AYRTON of Gorebrook Ironworks Manchester in the County of
Lancaster 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 :-
My said invention relates to improvements in the construction of automatic
spooling machines of the kind described in the Patent Specification of William
Weild No. 122 of A.D. 1858 and has for its object improved devices for actuating
the thread guides in order to ensure the parallel winding of the thread on the
bobbin.
In the accompanying drawings to which reference is hereinafter made I have

page_text: shown so much of such a machine as is needful to explain the nature and application
of my said invention.
As commonly arranged the thread guides (which are carried in the guide
holders i swinging on the shaft ¹) rest immediately on the layers of thread on the
bobbins which are being wound and are gradually lifted by the thread itself as
the successive layers cause the diameter to increase. In the event therefore of the
thread being unevenly wound in some of the inner layers the unevenness will be
continued through the whole bobbin and if as is usually the case the whole of the
thread guides are connected so as to move simultaneously the rest of the bobbins
which are being wound will to some extent partake of the irregularity of the faulty
bobbin.
According to my said invention I provide means for raising the guides by the
positive action of mechanism instead of in the above described manner.
I provide a sliding bar a Figs. 1 and 2 working lengthwise of the machine and
having (according to one way of carrying into effect my said invention) inclined
planes taking against bowls or rollers e pivoted to the framing of the machine so
that as the bar a travels in the direction of the arrow a¹ it is gradually raised.
The sliding bar a is operated by the swinging lever m having its fulcrum at m¹ and
having a stud m² adjustable in the slot m³ for the purpose of varying the stroke.
The upright arm n of a bell crank lever having its fulcrum at n' bears against the
stud m² and as the lower arm n² of the bell crank lever is raised by the rotation
of the cam d the bar a is pushed forward in the direction of the arrow a¹. The
shaft e on which the cam d is mounted is caused by suitable wheel gearing to make
a single revolution during the time necessary for filling a bobbin. By means of a
right and left hand screwed coupling of the bar a may be adjusted so as to time the
commencement of the vertical lift to suit the other motions. At f f I provide
bell crank levers the horizontal or nearly horizontal arms of which rest on the
upper edge of the said sliding bar a while their upright arms are connected by
adjustable links to swinging brackets h from which studs h¹ project and pass
through holes in the projections 2 of the guide holders i. When the bar a rises
the thread guides will be simultaneously lifted. In Figs. 1 & 2 a separate
weight to is shown for each thread guide for the purpose of determining the
pressure of the guide on the bobbin. By varying the position of the weight w in
relation to the fulcrum of the bell crank lever f the pressure of the guide may be
adjusted as desired.
At o Fig. 2 is a wheel or cam having therein a notch o¹ which by mechanism
already well known in connection with thread spooling machines is caused to make
a single revolution when the winding is finished. I make use of such wheel or cam
in connection with my said invention for the purpose of lifting the whole of the
thread guides and keeping them clear of the bobbins during the time the full bobbins
are being replaced by empty ones. One end of a lever having its fulcrum at p² is
provided with a bowl p¹ bearing against the periphery of the cam o. During the
filling of the bobbins and while the cam o is stationary the bowl p² rests in the
notch o¹. When however the bobbins are filled and the wheel or cam o begins to
rotate the bowl pl is lifted and the other arm p of the lever is depressed and remains
depressed until the revolution of the notch o' is completed. The arm p of the lever
is connected by the chain r with the sliding bar a. When the lever p is depressed
the bar a is drawn so far forward as that its vertical lift is sufficient to raise the
guides clear of the bobbins and they remain in this position during the rotation of
the cam o thus allowing sufficient time for the change of bobbins to be effected.
When the arm pof the lever again rises by the bowl p¹ falling into the notch o¹ the
bar a descends by its own weight aided by the weights w and in descending it
retrogrades to its initial position and the winding of the fresh bobbins can begin.
It is evident that the details of my said invention may be considerably varied and
modified without departing from its essential features. For instance instead of a
combined horizontal and vertical motion the bar a may have a simple horizontal
motion and instead of the bell crank levers simply resting on the bar a they may

page_text: be caused to engage therewith. Such a modification is shown in Fig. 3. In this
example the arms of the bell crank lever f¹ are both horizontal. The lower arm
engages with the bar a the forward motion of which causes the lever f¹ to turn
about its upright fulcrum or axis. The effect in the latter case is the same as that
hereinbefore described with reference to Figs. 1 & 2. In Fig. 3 the weights for
determining the pressure on the guides are collected together and by adding to or
taking from the collection of loose weights or discs to the pressure of the guides
may be varied at will.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a spooling machine the thread guide controlling apparatus substantially as
herein before described and shown in the accompanying drawings.
2. In a spooling machine the use of a longitudinally sliding bar operated by a
cam and adjustable links and levers for the purpose of operating and controlling the
thread guides substantially as herein before described and shown with reference
to the accompanying drawings.
3. The combination of the cam d the bell crank lever n the swinging lever m the
longitudinally sliding bar a the bell crank levers for f¹ and the connecting links g
for the purpose of operating and controlling the simultaneous action of the thread
guides substantially as hereinbefore described and shown with reference to the
accompanying drawings.
4. The use along with a sliding bar and the other elements of the combination set
forth in Claim No. 3 of inclined planes and rollers for raising the sliding bar as the
diameter of the bobbins increase substantially as hereinbefore described and
shown.
