IMPROVEMENTS IN APPARATUS FOR PREPARING COTTON AND OTHER FIBRES FOR SPINNING
Year: 1875

page_text: LETTERS PATENT to Charles Henry Bazley, of Manchester, in the
County of Lancaster, Cotton Spinner, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR PREPARING COTTON AND OTHER FIBRES
FOR SPINNING.”
Sealed the 16th July 1875, and dated the 12th May 1875.
PROVISIONAL SPECIFICATION left by the said Charles Henry Bazley
at the Office of the Commissioners of Patents, with his Petition,
on the 12th May 1875.
I, CHARLES HENRY BAZLEY, of Manchester, in the County of Lan-
caster, Cotton Spinner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR PREPARING COTTON AND OTHER
FIBRES FOR SPINNING," to be as follows:-
In spinning yarn, and more particularly in fine counts of yarn since
the introduction of the fine roving or bobbin and fly frames, great
difficulty has been experienced in obtaining yarn of the same count on
each spindle of the mule or spinning frame. Now my Invention
consists in using such appliances in connection with the coiling of the
rovings on to the bobbins of the fine roving or bobbin and fly frames as

page_text: shall enable me to classify each individual bobbin according to the count
of roving wound upon it.
In carrying my Invention into operation it is necessary that the
roving or fly frame should have what is generally known as a tapering
motion, that is, an apparatus to wind the roving on the bobbing so as to
produce taper ends.
My improved bobbin is made with only one head or flange, on the
outside of which is fixed the bobbin nail, as usual. The barrel is por-
fectly cylindrical to near the upper end, where it is rounded off. On
the barrel of the bobbin I now draw or place a closely fitting cylindrical
paper tube, which must be from three-eighths to half an inch longer
than what is usually known as the lift of the frame. The bobbins with
the paper tubes on them are then placed on the spindles with the head
or flange downwards, and the frame is set to work in the usual manner.
The roving is thus coiled on to the tubes instead of on the barrel of the 1
bobbin, as heretofore." When a certain length of roving has been coiled
on each bobbin the frame is stopped by a self-acting apparatus, or a bell'
strikes, warning the attendant. The paper tubes with the rovings on
them are then doffed off the bobbins, leaving the bobbins on the spindles
ready for the next set. The paper tubes with the rovings are then taken 2
to the sorter, who classifies them by weight, either on fine scales,
which I prefer, on an instrument known as the quadrant.
or
The classified rovings are given to different spinners, and as each
spinner has thus in his creels rovings of equal weight and consequent
fineness the cops or bobbins of yarn produced from his spindles are all 2
of the same count one with another.
The paper tubes with the rovings are placed in the spinners' creels
upon my improved skewers, which are provided with a flange below and
a shoulder ahove, on which the paner tube fits easily.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 30
filed by the said Charles Henry Bazley in the Great Seal Patent
Office on the 10th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HENRY BAZLEY, of Manchester, in the County of Lancaster, Cotton
Spinner, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of May, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Henry Bazley, Her special licence
that I, the said Charles Henry Bazley, my executors, administrators,
and assigns, or such others as I, the said Charles Henry Bazley, my
executors, administrators, and assigns, should at any time agreco 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 APPARATUS FOR PREPARING COTTON AND OTHER FIBRES FOR
SPINNING," upon the condition (amongst others) that I, the said
Charles Henry Bazley, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, 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 Charles Henry Bazley, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) :—
In spinning yarn, and more particularly in fine counts of yarn since
the introduction of the fine roving or bobbin and fly frames, great
difficulty has been experienced in obtaining yarn of the same count on
each spindle of the mule or spinning frame. Now my Invention consists
in using such appliances in connection with the coiling of the rovings
on to the bobbins of the fine roving or bobbin and fly frames as shall
enable me to classify each individual bobbin according to the counts of
roving wound upon it.
In carrying my Invention into operation it is necessary that the
roving or fly frame should have what is generally known as a tapering
motion, that is, an apparatus to wind the roving on the bobbin so as to
produce taper ends.
My improved bobbin is made with only one head or flange, as shown

page_text: which is fixed the bobbin nail, as usual. The barrel is perfectly cylin-
drical to near the upper end, where it is rounded off. On the barrel of
the bobbin I draw or place a closely fitting cylindrical paper tube, as
shewn by dots in Fig. 1, and detached in Fig. 2, which must be from
three-eighths to half an inch longer than what is usually known as the 5
lift of the frame. The bobbins with the paper tubes on them are then
placed on the spindles of the roving frame with the head or flange
downwards, and the frame is set to work in the usual manner. The
roving is thus coiled on to the paper tubes, instead of on the barrel of
the bobbin, as heretofore. When a certain longth of roving has been 1
coiled on cach bobbin the frame is stopped by a self-acting apparatus, or
a bell driven by a series of wheels from the front roller strikes to give
warning to the attendant. The paper tubes with the rovings on them
are then doffed off the bobbins, leaving the bobbins on the spindles
ready for the next set. The paper tubes with the rovings on them are 1
then taken to the sorter, who classifies them by weight, either on fino
scales, or, which I prefer, on an instrument known as the quadrant.
The variously classified rovings are given to different spinners, and as
each spinner has thus in his creels rovings of equal weight and conse-
quent fineness, the cops or bobbins of yarn produced from the spindles 2
are all of the same count one with another.
The paper tubes with the rovings are placed on the spinners' crecls
upon my improved skowers, shewn in Fig. 3, which are provided with
a flange bolow, and a shoulder above, on which the paper tube fits
easily.
As the improved skewers with the rovings wound in the paper tubes
are much lighter than the bobbins and skewers usually employed it is
evident that less strain is put on the roving when it is drawn off, and
consequently considerably less twist may be put in the roving, and more
even yarn is produced, at the same time that the quantity of work
produced by the roving frame is increased.
My Invention may be modified by making the tubes of thin sheet
metal instead of paper, as above described.
Fig. 4 represents a split steel tube of the same dimensions as the
paper tube shewn in Fig. 2, which fits accurately on the cylindrical {
part of the bobbin, and on which the roving is coiled, and in order to
give the requisite adhesion to prevent the tube slipping out of the roving
