Year: 1867

page_text: LETTERS PATENT to William Busfield, John Busfield, and Joseph Busfield,
of Bradford, in the County of York, Worsted Spinners, for the Invention.
of "IMPROVEMENTS IN PREPARING SLIVERS OF WOOL FOR SPINNING AND.
DYXING."
Sealed the 15th May 1868, and dated the 18th November 1867.
PROVISIONAL SPECIFICATION left by the said William Busfield, John
Busfield, and Joseph Busfield, at the Office of the Commissioners of
Patents, with their Petition, on the 18th November 1867.
We, WILLIAM BUSFIELD, JOHN BUSFIELD, and JOSEPH BUSFIELD, of Bradford,
in the County of York, Worsted Spinners, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN PREPARING SLIVERS OF WOOL POR SPINNING
AND DYEING," to be as follows:-
This Invention relates to the balls formed of slivers of wool by winding
upon a spindle, and for further process in preparing for spinning such slivers
of wool it is desirable in unwinding therefrom to take the end of the sliver
which is in the interior of the ball and draw it out from thence to avoid
entanglement of the fibres (as would be the case if taken from the outer end
of the sliver), but in so doing twist is put into the sliver, which is objec-
tionable. It is therefore desirable to remove this twist before it goes to
the drawing box, to effect this is the object of our Invention, and consists in
rewinding the sliver as taken from the interior of the ball upon a fixed or non-
rotary bobbin or equal or nearly equal diameter to the spindle upon which the
ball was formed by means of an ordinary spindle and flyer, the bobbiu being

page_text: placed on the lifting rail, and the spindle passing through the bobbin so that
the diameter of the bobbin increases in the same ratio as the diameter of the
interior of the ball or the hole formed therein by the drawing out of the sliver.
For dyeing purposes a little twist is required to be left in the sliver, this we
effect by having the bobbin either larger or smaller in diameter than the spindle
upon which the ball has been formed,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Busfield, John Busfield, and Joseph Busfield, in the
Great Seal Patent Office on the 18th May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BUSFIELD, JOHN BUSFIELD, and JOSEPH BUSFIELD, of Bradford, in the County
of York, Worsted Spinners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs, and successors, give and grant unto us,
the said William Busfield, John Busfield, and Joseph Busfield, Her special
licence that we, the said William Busfield, John Busfield, and Joseph Busfield,
our executors, administrators, and assigns, or such others as we, the said
William Busfield, John Busfield, and Joseph Busfield, our 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 Invention for "IMPROVEMENTS IN PREPARING SLIVERS OF WOOL
FOR SPINNING AND DYEING," upon the condition (amongst others) that we, the
said William Busfield, John Busfield, and Joseph Busfield, our executors or
administrators, by an instrument in writing under our, or their, or one of our
or 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 we, the said William Busfield, John Busfield,
and Joseph Busfield, do hereby declare the nature of our said Invention,
and in what manner the sanie is to be performed, to be particularly described

page_text: and ascertained in and by the following statement thereof, and accompanying
Sheet of Drawings (that is to say) :-
*-
This Invention has relation to the balls formed of slivers of wool by winding
upon a spindle, and for further process in preparing for spinning such slivers of
wool it is desirable in unwinding therefrom to take the end of the sliver which
is in the interior of the ball and draw it out from thence to avoid entanglement
of the fibres (as would be the case if taken from the outer end of the sliver),
but in so doing twist is put into the sliver, which is objectionable. It is there-
fore desirable to remove this twist before it goes to the drawing box. To effect
this is the object of our Invention, and which consists in rewinding the sliver
as taken from the interior of the ball upon a fixed or non-rotary bobbin of
equal or nearly equal diameter to the spindle upon which the ball was formed
by means of an ordinary spindle and flyer, the bobbin being placed on the
lifting rail and the spindle passing through the bobbin so that the diameter
of the bobbin increases in the same ratio as the diameter of the interior of
the ball, or the hole formed therein by the drawing out of the sliver. For
dyeing purposes a little twist is required to be left in the sliver, this we effect
by having the bobbin either larger or smaller in diameter than the spindle
upon which the ball has been formed.
In order that the Invention may be clearly understood, we herein give
reference to an accompanying Sheet of Drawings of a machine or apparatus
suitably constructed for carrying out the same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 is a front elevation.
A is a ball of sliver which has been formed in the usual manner and is now
placed upon the table B to be unwound from its interior; C is a bobbin to
wind it upon which is placed upon a plate D resting upon a lifter E which is
operated by a mangle wheel motion G to produce the ordinary lifting and
lowering thereof; H is a spindle passing through the bobbin and entering the
boss of a strap pulley I which receives rotary motion by strap motion J from
another pulley K on the main driving shaft L. The spindle H is held at its
top end in an ordinary bearing so as to be readily removed therefrom for doffing,
and it carries an ordinary flyer M which when motion is given to the said
spindle winds the sliver upon the bobbin in the usual regular manner by the
action of the lifter.
It must now be understood that the barrel of the bobbin must be either
of the same diameter and length as the pin upon which the ball has been
wound in its formation or that the bobbin and pin are of such relative

page_text: diameters and lengths that the first one layer upon the bobbin will take up
just the same length of sliver as forms the inner one layer of the ball, hence
it will follow that the twist given to the sliver by the drawing of it out from
the interior as is well known to be the case will be taken out by the winding
of the said sliver on to the bobbin, thus the object of this Invention is
accomplished. And it will be easily seen that if a little twist is required
to be left in the sliver for dyeing or other purposes it may be done by having
a little difference in the relative diameters of the barrel of the bobbin and
the pin upon which the ball was formed.
In witness whereof, J, the said Joseph Busfield, for and on behalf of
myself and the said William Busfield and John Busfield, have here-
unto set my hand and seal, this Sixteenth day of May, One thousand
eight hundred and sixty-eight.
