Improvements in or relating to Thread-spooling Machines.
We, EDWARD BROOK, THOMAS JULIUS HIRST, EDWARD HILDRED CARLILE,
CHARLES LEWIS BROOK, and CHARLES BROOK, trading as Jonas Brook and
Brothers, of Meltham Mills, near Huddersfield, in the County of York, Manu-
facturers, and JONAS BROOK HIRST of Meltham Mills, aforesaid, Mechanic, do
hereby declare the nature of this invention to be as follows:-
This invention relates to thread-spooling machines.
--
One feature of the said invention relates to means for securing even winding by
preventing the wobbling of the spool which is so liable to occur in machines as
heretofore constructed.
With this object we provide a very long driving spindle that projects consider-
ably beyond the ordinary head-stock, and we provide an additional headstock or
bearing independent of the ordinary headstock or in some cases fixed thereto or
formed therewith for supporting the end of the said spindle. We prefer to employ
in this additional head-stock or bearing a cast iron bearing bush. By this con-
struction we overcome the tendency for the spindle to become crooked and to run
untrue owing to the one-sided pressure of the driving feather or key, and we are
thus enabled to run the spindle much more rapidly than heretofore and thereby
increase the output.
.
Also by the additional head-stocks we provide extra bearings for the spindle
shaft and other rods, and so get increased steadiness and less wear and tear.
We further provide for holding the spool more securely at the non-driving end.
This we effect by means of a conical shaped centre bit in lieu of a cylindrical one
hitherto employed. The said centre bit accurately fits the hole in the bobbin and
prevents the shaking about of the latter when supported thereon. When employing
such a centre bit, the bobbin is liable to stick thereto instead of falling away when
the said centre bit is retracted for the purpose of discharging the filled bobbin. To
avoid this, we provide an adjustable stop or bracket against which the bobbin
strikes should it stick. The spool is thereby freed from the spindle and falls
away.
The wear of the bushes and spindles in our improved machine is much less than
is the case in machines as heretofore constructed.
Another feature of our invention relates to the provision of improved counting
mechanism for recording the number of layers of thread wound upon the spools.
This counter may be applied to self-acting spooling machines but it is more useful
in the small hand machines where the operator has usually to count the number
of layers wound upon the spool and consequently is liable to make mistakes and to
wind either too few or too many layers.
Our improved counter comprises a double incline or cam piece formed in or fixed
to the reciprocating spindle of the machine, and a rod working in guides and
adapted to be moved up and down by the said cam piece each time the spindle
is moved backward and forward. On the said rod is a pawl which engages with a
toothed counting disc and operates to turn the said disc intermittently. We may
arrange that the counting disc shall have the same number of teeth as the layers
of thread to be wound so that when the spool is full the disc will have made one
complete revolution and will be ready for starting afresh with the next spool, or
that the number of teeth in the said counting disc shall be a multiple of the layers
of thread to be wound in which case it is marked in suitable divisions so that when
the spool is full the disc will have moved to one of the said divisions.

page_text: A mark is formed in the disc to indicate in combination with a fixed pointer the
starting point.

COMPLETE SPECIFICATION.
Improvements in or relating to Thread-spooling Machines.
We, EDWARD BROOK, THOMAS JULIUS HIRST, EDWARD HILDRED CARLILE,
CHARLES LEWIS BROOK, and CHARLES BROOK, trading as Jonas Brook and
Bros. of Meltham Mills, near Huddersfield, in the County of York, Manufacturers,
and JONAS BROOK HIRST, of Meltham Mills, aforesaid, Mechanic, 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 aud by the following
statement:-
This invention relates to thread-spooling machines.
Que feature of the said invention relates to means for securing even winding by
preventing the wobbling of the spool which is so liable to occur in machines as
heretofore constructed.
We further provide for holding the spool more securely at the non-driving end,
and for freeing the filled spools from the spindle when it is desired to discharge
the same.
Another feature of our invention relates to the provision of improved counting
mechanism for recording the number of layers of thread wound upon the spools.
This counter may be applied to self-acting spooling machines but it is more useful
in the small hand machines where the operator has usually to count the number of
layers wound upon the spool and consequently is liable to make mistakes and to
wind either too few or too many layers.
In the accompanying drawings we have shown how our said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a side view of so much of a thread-spooling machine as is required
to illustrate our invention.
Figure 2 is a side view, and
Figure 3 a front view of a portion of a hand spooling machine provided with
our counting device.
Referring to Figure 1, A indicates the machine bed, and B the driving spindle
which is supported in suitable bearings in the headstocks C, C. We have shown
two independent headstocks for supporting the spindle, but in some cases we
employ one headstock only which is made much longer than those heretofore used
in machines of this kind so as to form a good support for the spindle B which is
also much longer than is usual. We thereby prevent wobbling of the spindle.
D is a long metal bush made preferably of cast iron which affords ample support
to the spindle and prevents the spindle running crooked or untrue, which is a great
fault of the short spindles heretofore used owing to the one sided pressure of the
driving feather or key. Such a spindle may be run much more rapidly than a
short spindle, thereby increasing the output of the machine. Moreover the
additional bearings afforded by the extra headstock or by the headstock of
increased length gives increased steadiness to the whole machine and reduces the
wear and tear.
For supporting the spool at the non-driving end, we employ a spindle E the
end E' of which is made slightly conical so as to fit accurately in the hole in
the spool and thereby prevent the latter from shaking about when rotating. With
such a conical centre bit however the bobbin is liable to stick thereto instead of
falling away when the said centre bit is retracted for the purpose of discharging

page_text: the filled bobbin. To avoid this, we provide a stop or bracket F adjustable on a
rod F and against which the bobbin strikes when the spindle is withdrawn to
discharge the same. The spool is thereby freed from the spindle and falls away.
The wear of the bushes and spindles in our improved machine is much less
than is the case in machines as heretofore constructed.
Referring now to Figures 2 and 3 G is a small bracket secured to the frame of
the spooling machine and constructed to carry the counter which consists preferably
of a suitably graduated dial H and fixed finger, the dial being moved intermittently
each time a layer of thread is completed. The counter is actuated as follows, that
is to say, on a spindle I, which is reciprocated by the operator when filling the
spool, is adjustably fixed a cam piece K having a double incline which is arranged
to actuate a vertical rod L that rests by a pulley L' on said inclined faces,
and that works in guides and is adapted to be moved up and down by the said cam
piece each time the spindle I is moved backward and forward. The said rod
controls a lever M on which is adjustably fixed a pawl N which engages with a
toothed disc O and operates to turn the said disc intermittently. The lever M is
slotted so as to be capable of sliding longitudinally on the axle of the ratchet disc O.
The dial forms a part of or is attached to the disc O. We may arrange that the
disc O shall have the same number of teeth as the layers of thread to be wound so
that when the spool is full the disc will have made one complete revolution and will
be ready for starting afresh with the next spool, or that the number of teeth in the
said counting disc shall be a multiple of the layers of thread to be wound, in which
case it is marked in suitable divisions, so that when the spool is full the disc will
have moved to one of the said divisions. A mark is formed in the disc to indicate
in combination with a fixed pointer the starting point.
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 means for steadying the spool at the non-driving end, in com-
bination with the device for freeing the spool, substantially as described, for the
purpose specified.
2. A thread-spooling machine constructed substantially as described with reference
to Figure 1, and operating as specified.
3. The combination, with a thread-spooling machine, of a counting device,
constructed substantially as herein described, for the purpose specified.
4. A hand thread-spooling machine having our improvements for counting the
layers wound on the spool embodied therein, substantially as described with reference
to Figures 2 and 3 of the drawings, and operating as specified.
