Improvements in Balling or Winding Frames.
We HENRY WREN, HENRY CHARLES WREN, and FREDERIC WREN, all of
London Road Iron Works, Manchester, in the County of Lancaster, Engineers
and Machinists, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for balling yarn but is also applicable to other
winding machinery.
In the first place we modify the mechanism for actuating the swing frame which
carries the spindles, by using a cam plate with adjustable or interchangeable
projecting plates or parts on the edge thereof and connecting the bell cranked
lever (which carries the bowl running on the edge of the said cam) to a second
cranked lever to which the link attached to the swing frame is connected. A.
weighted lever provided with a bowl or finger bears upon the end of the first
named bell cranked lever, the weight thereof being fixed to a rope or its equivalent
passing up from the lever and over a suitable pulley fixed on the frame of the
machine. Thus the weight of the swing frame is counter-balanced and the tendency
to back-lash and breakage of the teeth of the driving gear when the machine is
stopped is therefore greatly reduced.
The second part of the invention relates to mechanism for doffing the balls
when finished, severing the threads and holding the ends ready for restarting
the frame.
For this purpose we employ a doffing rail provided with a series of shells or
tubes surrounding the lower end of the spindles and each formed with a suitable
flange, to act against the underside of the ball on the spindle. This rail also
carries a series of fixed brackets carrying cutting edges each adjustable with regard
to its spindle according to the size of ball required. Each bracket is also made or
provided with a holding plate, between which and the cutting edge is pivotted a
small cranked lever one end of which is hooked and the other end is connected
to a light rod passing through the spindle rail and provided with two collars or
stops at a suitable distance apart one above and the other below the said
spindle rail.
The action of the apparatus is as follows:-
When the ball is complete the doffing rail above-named is raised by a hand
lever and rack or other gearing which may also be worked automatically.
As the rail rises it carries with it the flanged shells or tubes above named which
push the balls towards the end of the spindles. As the rail rises further, the stop
beneath the spindle rails upon each rod or wire hanging from the cutting hook
lever comes against the said spindle rail and arrests the said rod causing its lever
to be depressed and bringing down the hook between the cutting and holding plates.
The latter plate is higher than the former and thus the thread which has been
caught by the hook is brought down first between the said hook and the holding
plate which are close together and thereby held fast. The hook descends still
further bringing the thread or yarn against the cutting plate which cuts the same.
Each ball is then pushed (by the raising of the doffing rail) off the end of its
spindle, and falls into a convenient receptacle beneath.
The doffing rail can then be lowered for some distance the holding plate still
retaining the end coming from the flyer and the frame is then restarted to wind
fresh balls.

page_text: The rail can then be let.down close to the spindle rail the stops upon the rods
above the said spindle rail causing all the hooks to be raised ready for the next
doffing operation.
When the doffing rail is worked by a hand lever the latter is arrested by a
spring catch and fixed notched quadrant for restarting the frame as above
described.
It is evident that the above doffing mechanism can be applied to many kinds of
winding machinery.

COMPLETE SPECIFICATION.
Improvements in Balling or Winding Frames.
We HENRY WREN, HENRY CHARLES WREN, and FREDERIC WREN all of
London Road Iron Works Manchester, in the County of Lancaster, Engineers
and Machinists, 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:-
This invention relates to machines for balling yaru but is also applicable to other
winding machinery.
Our invention will be readily understood from the following description on
reference to the two annexed sheets of drawings.
On Sheet 1 Fig. 1 is an end elevation of so much of one of our improved
balling frames as is necessary to illustrate our invention.
On Sheet 2 Fig. 2 is a detached plan drawn to a smaller scale of the compound
levers for counterbalancing the swing frame as hereafter described.
Figs. 3, 4, 5 and 6 are detached views drawn to a larger scale of a spindle rail
and spindles with our improved doffing motion applied thereto.
In the first place we modify the mechanism for actuating the swing frame a
which carries the spindles 6 by using a cam plate c with adjustable or interchangeable
projecting plates or parts c¹ on the edge thereof see Fig. 1 and connecting the bell
cranked lever d (which carries the bowl d' running on the edge of the said cam c)
to a second cranked lever d² (see also Fig. 2) to which the link a' attached to the
swing frame a is connected. A weighted lever d³ provided with a bowl d* (or a
finger) bears upon the end of the first named bell cranked lever d the weight d³
thereof being fixed to a rope or its equivalent passing up from the lever at the
point d and over a suitable pulley fixed on the frame of the machine, or being
hung on the other side of the fulcrum as seen at Figs. 1 and 2. Thus the weight
of the swing frame a is counterbalanced and the tendency to back-lash and
breakage of the teeth of the driving gear when the machine works round to the
projecting plates c' is therefore greatly reduced, or even avoided entirely.
The second part of the invention relates to mechanism for doffing the balls
when finished, severing the threads and holding the ends ready for restarting the
frame.
For this purpose we employ a doffing rail e see enlarged views Figs. 3, 4 and 5,
provided with a series of shells or tubes el surrounding the lower end of the spindles b
and each formed with a suitable flange e to act against the underside of the ball on
the spindle b. This rail e also carries a series of fixed brackets f carrying cutting
edges g each adjustable as shewn with regard to its spindle according to the size
of ball required. Each bracket is also made or provided with a holding plate h
between which and the cutting edge g is pivotted a small lever or cutting hook i
which is hooked or curved as shewn. The levers i are mounted on a shaft i on

page_text: which is an arm connected to a light rod k passing through a bush on the
spindle rail and provided with two collars or stops m and m' at a suitable distance
apart one above and the other below the said spindle rail l'.
The action of the apparatus is as follows:-
When the ball is complete the doffing rail e above named is raised by a hand
lever and rack e see Fig. 1 or other gearing which may also be worked
automatically.
As the rail e rises it carries with it the flanged shells or tubes e¹ above named
which push the balls towards the end of the spindle b. As the rail rises further
the stop m', beneath the spindle rail , upon the light rod or wire k hanging from
the cutting hook lever comes against the bush fixed to the said spindle rail l
and arrests the said rod k causing the said lever to be depressed and bringing
down the hook i between the cutting plate g and holding plate h. The latter is
higher than the former and thus the thread which has been caught by the hook i is
brought down first between the said hook and the holding plate h which are close
together and thereby held fast. The hook i descends still further bringing the
thread or yarn against the cutting plate 9 which cuts the same. Each ball is then
pushed (by the further raising of the doffing rail e) off the end of its spindle b, and
falls into a convenient receptacle beneath.
The doffing rail e can then be lowered for some distance as seen at Fig. 1 so that
the end of the cutting hook i will not be in the way of the flyer n the holding
plate still retaining the end coming from the flyer n Fig. 1 and the machine is
then restarted to wind fresh balls.
The rail e can then be let down close to the spindle rail
on the drawings Figs. 3 and 4 the stops m upon the rods k
rail coming against the bush and causing all the hooks to
next doffing operation.
into the position shewn
above the said spindle
be raised ready for the
When the doffing rail is worked by a hand lever as seen on Fig. 1 the latter is
arrested by engaging with a fixed.notched quadrant o for restarting the frame as
above described (or a separate spring catch may be employed in combination with
this notched quadrant).
It is evident that the above doffing mechanism can be applied to many kinds of
winding machinery.
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 improved mechanism for actuating the swing frame substantially as
hereinbefore described and illustrated by the annexed drawings.
2. The improved doffing motion constructed and operating substantially as
hereinbefore described and illustrated by the annexed drawings.
