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 WILLIAM KENYON, of Meltham Mills aforesaid, Mechanic, do hereby declare
the nature of this invention to be as follows:-
This invention relates to thread-dressing machines, and its chief object is to
ensure perfect uniformity of treatment throughout the entire length of the thread.
Heretofore it has been the usual practice to draw the threads through the
machine by means of the beams on which the finished threads are wound, and in
order that the threads may be drawn through at an approximately regular speed
the speed of the beams is gradually reduced as they fill with thread. It has been
necessary however for the attendant to control the speed-reducing mechanism as
the beams fill according to his or her judgment and it is found in practice impossible
to secure absolute uniformity of speed of the threads. Consequently the work
done is uneven.
The chief object of this invention is to provide for ensuring perfectly even work.
We effect this by feeding the threads into the machine from the delivery beam by
a pair of feed rollers, which we prefer shall be the starching rollers, and which are
driven positively at a uniform speed, and by so driving the beams which receive the
finished thread, that all the thread fed into the machine is taken up by the said
beams at a uniform rate and maintained at a uniform tension.
Our said invention comprises mechanism for automatically controlling the speed
of the take-up beams by the movements of a tension device.
In carrying our invention into practice we drive the starching rollers positively
by worm, spur, or belt mechanism and we provide suitable change wheels, or
inverted cones so that the speed of the said rollers can be readily varied to suit the
character of the work to be done. By this means the thread is fed into the machine
at a perfectly uniform rate. These small cones actuate a dial which shows at a
glance what speed the frame is set at, and by moving a handle the speed can be
diminished or increased without stopping the frame. We also drive the beams
which receive the finished thread positively preferably through a pair of inverted
cones and to ensure perfect correspondence between the speed at which the said
beams take in the thread and that at which the starching rollers give it out, we
provide a controlling motion as follows. That is to say, we rest on the threads
preferably just behind the starching rollem a tension roller which is suitably
weighted to produce the desired tension. The said roller is connected by rods or
links and levers with a fork which engages with the boss of a double cone which is
constructed to be free to slide on its driving shaft while being compelled to rotate
therewith. The said cone for example is driven by a feather key. By moving the
said fork about its pivot, one or other of the two faces of the double driving cone
can be brought into contact with a driven cone which is intermediate of the two
faces of the said double cone. The said driven cone is rotated in one direction
when in contact with one face of the double cone and in the other direction when
in contact with the other face of the double cone. The said driven cone operates
to rotate a screwed spindle which is connected with the guiding fork of the belt of
the inverted cones that drive the thread-receiving beams. When the said screwed
spindle is rotated, the guide fork is moved in one direction or the other and the said
cone belt is shifted, thereby changing the speed of the thread-receiving beams.

page_text: The driven cone aforementioned may be otherwise connected to the belt guiding
fork so as to move it when the cone is rotated.
The operation of this mechanism is as follows. Should the speed of the take-up
beams be too slow, the threads will bag and allow the tension roller to fall slightly
and this will have the effect of moving the double cone so as to bring one of its
faces into contact with the intermediate cone and thereby rotate the said cone and
shift the position of the inverted-cone belt so as to drive the take-up beams more
quickly. If on the other hand the take-up beams are rotating too quickly and the
thread is therefore being taken up too fast, the tension roller is raised and the
inverted-cone belt is thereby moved slightly in the other direction so as to slow
down the take-up beams to the proper speed. There is thus a constant checking
action going on which maintains the take-up rollers at the proper speed, no matter
how much or how little thread has been wound thereon.
The tension roller rides quite freely on the threads and is free to move up and
down. It therefore maintains the threads at a perfectly uniform tension.
It is obvious that with our present improvement the thread is subjected at every
portion of its length to the same treatment and is wound upon the take up beams in
a state of uniform dryness throughout. Consequently even work is the result.

Improvements in Thread-dressing 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 WILLIAM KENYON 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 and by the following statement :-
This invention relates to thread-dressing machines, and its chief object is to
ensure perfect uniformity of treatment throughout the entire length of the thread.
Heretofore it has been the usual practice to draw the threads through the
machine by means of the beam on which the finished threads are wound, and in
order that the threads may be drawn through at an approximately regular speed so
as to secure uniform treatment as far as possible the speed of the beam is gradually
reduced as it fills with thread. The control of the speed-reducing mechanism was
left to the attendant, who varied the speed as might seem to be required according
to his or her judgment. It is found in practice impossible with this method to
secure absolute uniformity of speed of the threads. Consequently the work done
is uneven.
According to our invention we ensure perfectly even work as follows, that is to
say, we feed the threads into the machine from the delivery beam by a pair of feed
rollers, which we prefer shall be the starching rollers, and which are driven
positively at a uniformn speed, and we automatically control the beam which receives
the finished threads so that all of the said threads are taken up by the said beam
at a uniform rate and maintained at a uniform tension.
Our said invention comprises mechanism for automatically controlling the speed
of the take-up beam by the movements of a tension device.
Referring to the accompanying drawings which illustrate our invention.
Figure 1 is a plan, and
Figure 2 is a side elevation of so much of a thread-dressing machine as is required
to illustrate our invention.
A. is the machine frame; B is the delivering thread beam; C is the beam for
:

page_text: receiving the finished threads; and DD are the starching rollers. E is the main -
driving shaft. The receiving beam C is driven positively from the said shaft E
through a pair of inverted cones F, F and intermediate gearing indicated by dotted
lines in Figure 2, and its speed can be varied by shifting in a manner hereinafter
described the belt F¹ which connects the said inverted cones. The starching
rollers D, D are driven positively and at a uniform rate for each class of work, and
they serve as the feeding rollers which determine at what rate the work shall be
done. One convenient mode of driving the starching rollers is through worm gear G,.
vertical shaft H, inverted cones I, I, and rope J which is driven by a pulley on the
main shaft E. The inverted cones I, I, admit of very readily changing the speed of
the starching rollers to suit different classes of threads. Any suitable belt-shifting
device may be employed to move the belt of the said cones. We prefer to so
arrange that the said belt-shifting device shall when operated actuate an indicator
by means of which the speed of the starching rollers can be seen at a glance, and
by which the adjustment of the speed to any desired degree is facilitated without
necessitating the stoppage of the machine. For instance we may arrange to move
the belt fork by a screwed spindle on which is fixed a worm that gears with a worm
wheel of the indicating device. When the screwed spindle is rotated by its appro-
priate handle to shift the belt, the indicator finger will be moved over a dial which
is suitably marked to show the speed at which the threads are being delivered for
all positions of the driving belt. In lieu of the inverted cones above described for
driving the starching rollers we may employ change wheels which can be varied to
suit the character of the work.
.
To ensure perfect correspondence between the speed at which the beam C takes
in the threads and that at which the starching rollers give them out, we provide a
controlling motion as follows. That is to say, we rest on the threads at a point
between the starching rollers and an adjacent support K. a tension roller L which is
weighted by a rod L', which is suitably guided, and a loaded lever M. to produce
the desired tension. The said lever M which is pivoted at M' is connected by
suitable connections such as an arm M², rod N, and forked bell-crank lever O with
the boss of a double cone P, which is constructed to be free to slide on the driving
shaft E while being compelled to rotate therewith. The said cone for example is.
driven by a feather key. By moving the said fork about its pivot O' one or other
of the two faces of the double driving cone P can be brought into contact with
a friction cone Q which is intermediate of the two faces of the said double
cone. The said cone Q is rotated in one direction when in contact with one
face of the double cone and in the other direction when in contact with the
other face of the double cone. The said driven cone operates through gearing R
to rotate a screwed spindle which is connected with the guiding fork S of
the belt of the inverted cones F, F that drive the thread-receiving beam.
When the said screwed spindle is rotated, the guide fork is moved in one
direction or the other and the said cone belt is shifted, thereby changing the
speed of the thread-receiving beam. The fork S is supported by and slides on
a guide bar S¹ which also serves to support the screwed spindle that operates
the fork. The driven cone aforementioned may be otherwise connected to the
belt-guiding fork so as to move it when the cone is rotated.
The operation of this mechanism is as follows; should the speed of the take-
up beam be too slow, the threads will bag and allow the tension roller L to
fall slightly and this will have the effect through the rod L, lever M, arm M³,
rod N, and forked bell-crank lever ☐ of moving the double cone P so as to
bring one of its faces into contact with the intermediate cone Q and thereby
rotate the said cone and move the belt fork S, thus shifting the position of the
inverted cone belt so as to drive the take-up beam more quickly. If on the
other hand the take-up beam is rotating too quickly and the threads are thereby
being taken up too fast, the tension roller L is raised, and the other face of
the cone P is pressed against the cone Q which then operates to move the belt F1
slightly in the other direction so as to slow down the take-up beam to the

page_text: proper speed. There is thus a constant checking action going on which main-
tains the take-up beam at the proper speed, no matter how much or how little
thread has been wound thereon.
When the beam is rotating at the proper speed, neither face of the cone P
is in contact with the cone Q and consequently the latter remains stationary
and the belt F' is not moved.
The tension roller L rides quite freely on the threads and is free to move up
and down. It therefore maintains the threads at a perfectly uniform tension.
It is obvious that with our present improvements the thread is subjected at
every portion of its length to the same treatment and is wound upon the take-
up beam in a state of uniform dryness throughout. Consequently even work is
the result.
When the beam C having been filled is replaced by an empty beam, the
belt F¹ must be run back to the other end of the inverted cones from that to
which it has been gradually moved as the beam filled. To facilitate the running
back of the said belt we provide a catch T which can be set to hold down the
lever M and thus maintain the proper face of the cone P in contact with the cone Q
until the belt is returned to 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. A thread-dressing machine wherein the thread is fed into the machine at a
uniform rate and is maintained at a uniform tension, and taken up as required by the
receiving beam, for the purpose specified.
2. A thread-dressing machine wherein the thread is fed into the machine at a
uniform rate, and the receiving beam is driven by a variable speed mechanism which
is controlled by a thread-tension device, substantially as described, for the purpose
specified.
3. The means for controlling the speed of the receiving or take-up beam according
to the variations in the length of thread between the said beam and the delivering
rollers, substantially as described, for the purpose specified.
4. The tension device, constructed and operating substantially as described with
reference to the drawings.
5. In a thread-dressing machine, the means for driving and readily varying the
speed of the delivery rollers, in combination with a device for indicating the speed, a
substantially as described.
6. A thread-dressing machine constructed substantially as described with refer-
ence to the drawings and operating as, and for the purpose, specified.
