Year: 1859

page_text: LETTERS PATENT to John Bolton, of Halifax, in the County of York,
Manufacturer, for the Invention of "IMPROVEMENTS IN MEANS OR
APPARATUS FOR WINDING THREAD OR YARN ON
YARN ON TO SHUTTLE BOBBINS OR
PIRNS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN WINDING ON TO OTHER
BOBBINS OR SPOOLS OR TUBES."
Sealed the 27th April 1860, and dated the 31st October 1859.
PROVISIONAL SPECIFICATION left by the said John Bolton at the
Office of the Commissioners of Patents, with his Petition, on the 31st
October 1859.
I, JOHN BOLTON, of Halifax, in the County of York, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MEANS
OR APPARATUS FOR WINDING THREAD OR YARN. ON TO SHUTTLE BOBBINS OR PIRNS,.
WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN WINDING ON TO OTHER BOBBINS OR
SPOOLS OR TUBES," to be as follows:-
The object of the improvements is to vary the amount of traverse of the
thread or yarn as laid on to bobbins or pirns, in order that the successive
layers of it may extend a shorter and shorter distance, and a conical or such
like form thereby be given to the ends of the quantity so laid. The bobbins.
or pirns are supported in frames in which they are held by weights, and they
have surface motion given to them by cylinders or drums, whilst the thread or
yarn is laid thereon by conductors. by which the amount of traverse of the

page_text: thread is reduced by the accumulation effected. By one method each con-
ductor turns upon a hinge joint, or is otherwise capable of rising upon one
part of a lever, and these levers have motion given them adapted to the
length of the bobbins or pirns to be filled, and during the filling the outer or
feed end of each conductor rests upon and is raised by the accumulation of
thread or yarn by which its extent of traverse is reduced, and the desired form
thereby given to the quantity of yarn or thread laid. The thread or yarn
may also simply rise by resting on the accumulated thread whilst guided in a
slot or guide with diminished traverse by such rising, and these means may
be otherwise varied. When the bobbins or pirns have received the quantity
of thread or yarn desired they rise on their supporting frames and move from
contact with the cylinders or drums by which motion to them is obtained,
and the further winding thereon ceases. The means for regulating the laying
on of the thread or yarn is also applicable in other processes for filling or
winding on to bobbins, spools, or tubes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Bolton in the Great Seal Patent Office on the
30th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BOLTON, of Halifax, in the County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of October, in the year of
our Lord One thousand eight hundred and fifty-nine, in the twenty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Bolton, Her special licence that I, the
said John Bolton, my executors, administrators, and assigns, or such others
as I, the said John Bolton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at.
all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MEANS OR APPARATUS FOR WINDING THREAD OR
YARN ON TO SHUTTLE BOBBINS OR PIRNS, WHICH IMPROVEMENTS ARE ALSO
APPLICABLE IN WINDING ON TO OTHER BOBBINS OR SPOOLS OR TUBES," upon the
condition (amongst others) that I, the said John Bolton, my executors or
administrators, by an instrument in writing under my or their, or one of

page_text: their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,.
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Bolton, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
The object of the improvements is to vary the amount of traverse of the
thread or yarn as laid on to bobbins or pirns, in order that the successive layers
of it may extend a shorter and shorter distance, and a conical or such like
form thereby be given to the ends of the quantity so laid. The bobbins or
pirns are supported in frames in which they are held by weights, and they have
surface motion given to them by cylinders or drums, whilst the thread or yarn
is laid thereon by conductors, by which the amount of traverse of the thread
is reduced by the accumulation effected. By one method each conductor turns
upon a hinge joint, or is otherwise capable of rising upon one part of a lever,
and these levers have motion given them adapted to the length of the bobbins
or pirns to be filled, and during the filling the outer or feed end of each con-
ductor rests upon and is raised by the accumulation of thread or yarn by which
its extent of traverse is reduced, and the desired form thereby given to the quan-
tity of yarn or thread laid. The thread or yarn may also simply rise by resting
on the accumulated thread whilst guided in a slot or guide with diminished
traverse by such rising, and these means may be otherwise varied. When the
bobbins or pirns have received the quantity of thread or yarn desired, they rise
on their supporting frames and move from contact with the cylinders or drums
by which motion to thein is obtained and the further winding thereon ceases:
But that the nature of these improvements, and the means which I adopt in
carrying the same into effect may be fully understood, I will proceed to describe
the Drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view of apparatus for winding thread on to shuttle
bobbins or pirns; Figure 2, a transverse section, and Figure 3, a front view of
portions of the same; Figures 4 and 5 show some of the parts separately, and

page_text: motion from a steam engine or other suitable power. c is one of the bobbins
or pirns being filled by thread or yarn drawn from a bobbin d, and whilst
being filled the bobbin is by its spindle or axis c supported in slots e¹ formed
in the plates e, e, and each bobbin or pirn has surface motion given to it by
resting on the periphery of a drum or cylinder f affixed to and moving round
with the axis b. The surfaces of the drums or cylinders fare covered with
leather or other suitable material, and the bobbins or pirns are borne thereon
by means of the weighted levers g, which turn upon axes g', and at 9' are
connected to the rods h, the upper ends of which are formed with hooks to rest
and bear on the spindles c¹. i is a conductor for the thread or yarn as laid on
to the bobbin or pirn, and according to one arrangement for effecting my
improvements the conductor is by hinge joint connected to the lever i,
which at its lower end is connected with capability of turning freely on the
pin carried by the traversing bar it, whilst its upper part is formed with a
slot by which it is capable of motion on the fixed pin is of the stationary bar
1. The traversing bar it is connected, as shown by the pin i* to the upper end
of the lever i', and so as to be moved to and fro by motion given to that lever,
and the motion is given to the lever i' by means of the heart-shaped cam is
on the axis acting on the truck or bowl 10 carried by the lever i', whilst the
truck or bowl 10 is kept bearing against the surface of the cam is by the
spring acting against the lever . The axis i is carried by the stationary
bearings a³, and has affixed upon it the pinion i, which receives motion froni
the worm wheel on the axis b. The outer or feed end of each conductor i
rests upon the bobbin or pirn to be filled, and the amount of motion given to
the bar is regulated, so that each conductor in first laying thread on to a
bobbin or pirn c covers it to the full extent desired, but as the bobbin or pirn
fills and the outer or feed end of the conductor is thereby raised the distance
of the point of feed from the axis of motion i³ becomes lessened, and conse-
quently the distance of traverse of such point is reduced, and the desired conical
form to the quantity of thread wound on to the bobbins or pirns is obtained.
I do not confine myself to this method of causing the feed part of the con-
ductor to rise as a shortening of the amount of leverage to obtain the desired
effect may be otherwise produced. And in Figures 6 and 7, I have shewn a
method by which the same effect may be obtained, by simply guiding the
thread or yarn on to the bobbin or pirn to be filled by passing it through a
slot in a lever is, by which it will rise thereon as the thread accumulates on
the bobbin or pirn, and the desired progressive shortening of the distance of
traverse obtained the slots e¹ in the plates are so arranged that when the
desired amount of yarn or thread is accumulated, the axis c will have risen to

page_text: the horizontal portion of such slots, when those axes will be moved forwards
and cease to be acted upon by the surface of the respective drums or cylinders,
by means of the spring acting on the lower end of the rod h, as shown by
Figure 8. The amount of yarn obtained on the axis c¹ may be varied by
adjusting the height of the plate e³, upon which is formed the surface e by the
set screws e. The means for regulating the laying on of the thread or yarn
is also applicable in other processes for filling or winding on to bobbins, spools,
or tubes.
Having thus described the nature of my Invention and the means which I
have found to answer well in carrying the same into effect, I would have it
understood that I do not confine myself to the precise arrangement of parts
shown, as these may be varied without departing from my Invention; but
what I do claim is the adaptation and combination of means and mode of
operating for the winding of thread or yarn on to bobbins, or spools, or tubes,
substantially as explained.
In witness whereof, I, the said John Bolton, have hereunto set my hand
and seal, this Twenty-sixth day of April, in the year of our Lord
One thousand eight hundred and sixty.
