Improvements in Machines for Balling Thread or Yarn.
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 improvements upon the self acting thread balling
machine for which Letters Patent No. 5498 dated March 28th 1891 were granted
to Henry Wren and Henry Charles Wren.
The machine consists principally of a main frame to the front part of which is
attached levers, a swinging frame carrying a series of spindles, which are driven by
bevil wheels on a shaft, carried in the said swing frame and actuated by pulleys and
endless hands or cords or otherwise from the main driving shaft as before.
The swinging motion is imparted to the swing frame by means of bell crank levers
and links actuated by a cam or cams on a cam shaft driven by an endless chain
from the main shaft but according to our present invention we prefer to allow the
bowl of the bell crank lever to work on the outer edge of the cam which we can
modify in form so as to give any required "fancy" shape to the balls.
For this purpose we make a recess in the periphery of the cam plate at the point
where the depression for "covering in" (i.e. forming a web over the ticket hereafter
described) is to be situated and we fill this recess in with a removable and adjustable
section so that the depression may be altered or made deeper according to the
requirements of any special shape or make of ball.
The flyers are mounted in a fixed rail and are driven by toothed or frictional
gearing from the main shaft.
On the end of each spindle is screwed a small box which is supplied with an
adhesive cement. When the balls are ready for "netting" the machine stops, and
the attendant places a ticket upon the adhesive end of each spindle, and then sets
the machine on again for "netting."
We also actuate the stop motion when required for such "netting," or for stopping
the winding of the ball directly from the cam shaft of the machine, providing the
catch lever which holds the strap on the fast pulley, with a projection which rests
on a tappet wheel or cam on the said cam shaft, and is released for "netting," or
for stopping the winding when the balls are completed, by being raised by
adjustable projections or tappets on the said tappet wheel or cam, and thus the
ratchet wheel, drum, chain, and other adjuncts for releasing the said catch lever,
described in the Specification of the above named Letters Patent are dispensed
with and the machine is made much more simple.
The alteration of the speed of the spindles for "netting" is also effected auto-
matically and directly from the crank shaft by connecting the netting lever to a
short sliding rod or bar at the other end of which is a bowl, held by a spring (or
equivalent means) against the face of a cam surface formed preferably upon the face
of the same cam plate which raises or lowers the swing frame by means of a
concentrically curved cam piece or pieces adjusted in a slot or slots in the said
cam-plate.
A creel is provided to support the bobbins off which the thread is wound, and
beneath each bobbin we may fix a cone or ring to prevent the "ballooning" of the
thread or yarn.
A drag motion is provided whereby the "drag" or tension upon the thread may
be varied as required.
This
max
he affected by lover holding the thread down upon
a plate or

page_text: balanced by the thread, the said lever being counterbalanced by suitable adjustable
weights, fluid, sand, or quicksilver.
Or we may pass the thread first beneath a rod or bar carried on a swinging
centrally pivotted frame or lever, which can be weighted as desired and then over
another bar at the other end of the frame or lever so that as the thread drags
against the flange of the bobbin as it is unwound therefrom it will lower the frame
or levers, and loosen the tension.
A. doffing motion is also provided and consists principally of a long rail which
when the balls are completed is raised by hand or otherwise and lifts all the balls
at one time off the spindles; meanwhile a second rail worked by similar means and
provided with a series of hooks rises beneath the first rail and catches the threads
and draws them down to secure the ends whilst a second series of hooks (or knife or
knives) descending lower on the said rail, sever all the ends from the balls.

Improvements in Machines for Balling Thread or Yarn.
L
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 improvements upon the self acting thread balling
machine for which Letters Patent No. 5498 dated March 28th 1891, were granted
to Henry Wren and Henry Charles Wren.
The invention will be readily understood from the following description on
reference to the annexed drawings of which
Fig. 1, is a face view of so much of one of our balling machines as is necessary
to illustrate the present invention.
Fig. 2 is an end elevation of the same with the swing frame and flyer rails in
section.
Fig. 24 is a detached view of a tappet hereafter referred to, and
Fig. 2 a detached plan of the tension device hereafter more particularly
described.
The machine consists principally of a main frame a to the front part of which is
attached by levers a swinging frame e carrying a series of spindles d which are
driven by bevil wheels e ou a shaft carried in the said. swing frame c and actuated
by pulleys and endless bands or cords or otherwise from the main driving shaft
as before.
The swinging motion is imparted to the swing frame c by means of bell crank
levers 9 and links g' actuated by a cam or cams on a cam shaft driven by an
endless chain upon a shaft driven from the main shaft, but according to our
present invention we prefer to allow the bowl g² of the bell crank lever y to work
on the outer edge of the cam 4 which we can modify in form so as to give any
required "fancy" shape to the balls.
For this purpose we make a recess in the periphery of the cam plate / at the
point where the depression for "covering, in" (i.e. forming a web over the ticket
hereafter described) is to be situated, and we fill this recess in with a removable
and adjustable section *.so that the depression may be, altered or, made deeper
according to the requirements of any special shape or make of ball.
The flyers i are mounted in fixed, rails, and are driven by. toothed or frictional
gearing from the main shaft.

page_text: On the end of each spindle d is screwed or otherwise fixed a small box dx
which is supplied with an adhesive cement (see Fig. 2). When the balls are ready
for "netting" the machine stops, and the attendant places a
ticket upon
the
adhesive end of each spindle and then sets the machine on again for "netting."..
We actuate the stop motion when required for such "netting or for stopping
the winding of the ball directly from the cam shaft ¹ of the machine, providing
the catch lever which holds the strap on the fast pulley m with a projection
which rests on a tappet wheel or cam on the said cam shaft and is released for
"netting or for stopping the winding when the balls are completed, by being
raised by adjustable projections or tappets on the said tappet wheel or cam 12 (sce
detached view Fig. 2A) and thus the ratchet wheel drum, chain and other adjuncts
for releasing the said catch lever described in the Specification of the above named
Letters Patent, are dispensed with, and the machine made much more simple.
"
The alteration of the speed of the spindles for "netting" is also effected
automatically and directly from the cam shaft by connecting the lever n to a short
sliding rod or bar n' (by the arm n² or otherwise) at the other end of which is a
bowl 3 held by a spring n' (or equivalent means) against the face of a cam surface
formed preferably upon the face of the same cam plate h which raises or lowers the
swing frame by means of a concentrically curved cam piece 4 (or pieces) adjusted
in a slot or slots in the said cam plate h.
A creel o is provided to support the bobbins off which the thread is wound, and
beneath each bobbin we may fix a cone o' or a ring to prevent "ballooning" of
the thread or yarn.
A drag bobbin is provided whereby the drag or tension upon the thread may be
varied as required.
This may be effected by a lever holding the thread down upon a plate, or
balanced by the thread, the said lever being counterbalanced by suitable adjustable
weights fluid, sand or quicksilver.
Or we may pass the thread first beneath a rod or bar p¹ carried on a swinging
centrally pivotted frame or lever p which can be weighted as shown at p² Figs. 1, 2
and 2" as desired, and then over another bar p' at the other end of the frame or
lever so that as the thread drags against the flange of the bobbin a (see Fig. 2)
as it is unwound therefrom it will rock the frame or levers p and loosen the tension.
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 form of cam plate with removable and adjustable parts fitted
in its periphery constructed and operating substantially as herein before described.
2. The combination with the spindles of a box to contain adhesive material for
ticketting the balls substantially as hereinbefore described.
3. The improved stop motion substantially as hereinbefore described and
illustrated by the drawings annexed.
4. The improved "netting" motion substantially as hereinbefore described and
illustrated by the annexed drawings.
5. The improved "drag-motion "substantially as hereinbefore described and
illustrated by Figs. 1, 2 and 2 on the annexed drawings.
Dated this 26th day of May 1893.
