page_text: LETTERS PATENT to John Sidebottom, of Harewood, near Mottram, in
the County of Chester, Cotton Spinner and Manufacturer, for the
Invention of "IMPROVEMENTS IN COP TUBES AND PARTIAL TUBES, AND IN
APPARATUS FOR HOLDING THEM ON TO THE SPINDLES OF MULES FOR SPINNING
AND DOUBLING, ALSO IMPROVEMENTS IN THE CONSTRUCTION OF THE SKEWERS
FOR SHUTTLES AND WINDING MACHINES,"
Sealed the 22nd August 1861, and dated the 20th May 1861.
PROVISIONAL SPECIFICATION left by the said John Sidebottom at
the Office of the Commissioners of Patents, with his Petition, on the
20th May 1861.
I, JOHN SIDEBOTTOM, of Harewood, near Mottram, in the County of
Chester, Cotton Spinner and Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN COP TUBES AND PARTIAL TUBES, AND
IN APPARATUS FOR HOLDING THEM ON TO THE SPINDLES OF MULES FOR SPINNING
AND DOUBLING. ALSO IMPROVEMENTS IN THE CONSTRUCTION OF THE SKEWERS FOR
SHUTTLES AND WINDING MACHINES," to be as follows:-
This Invention relates to certain improvements upon the Invention secured
to George James Wainwright and Charles Timothy Bradbury, by Letters
Patent, bearing date the 18th day of July 1e57, No. 1992, and it consists in
making the partial tubes described in the Specification of the said Letters
Patent of a conical form instead of cylindrical. The lower end of each
conical partial tube, when placed on the spindle, fits upon a flanged button or
[Price 8d.]

page_text: cop braid, which is loose ou the spindle, and holds the cone concentric with
the spindle. In doffing the full cops the attendant presses the cops up the
spindles by the loose button or braid, and the conical partial tube remains in
the cop while the button or braid is allowed to drop down the spindle on to
the fast ring, by which it is held in place until the succeeding set of conical
partial tubes are supplied to the spindles.
The machinery employed for placing the conical partial tubes on the
spindles is or may be similar to that secured to me by Letters Patent on the
16th day of April 1859, No. 961. When conical tubes are used instead of
partial tubes they are made, by preference, of sheet steel, and placed over the
ends of the spindles by hand, or by any of the known combinations of
machinery now employed in putting on the paper or other tubes at present
in use.
My improvements in the construction of the skewers for shuttles and
winding machines consists in making them with a conical projection, or with
as boulder on which the conical tube or partial tube fits, and by which it is
held concentric with the skewer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Sidebottom in the Great Seal Patent Office on the
16th November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SIDEBOTTOM, of Harewood, near Mottram, in the County of Chester, Cotton
Spinner and Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of May, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Sidebottom, Her special licence that I, the said John Sidebottom,
my executors, administrators, and assigns, or such others as I, the said Johu
Sicht on, my executors, administrators, and as igus, should at any time
agree with, and no others, from time to time and at all times thereafter during
tho term therein expressed, should and lawfully might make, use, exercise,

Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN COP
TOFIS AND PARTIAL TUBE3. AND IN APPARATUS FOR HOLDING THEM ON TO THE
SPINDIES OF MULES FOR SPINNING AND DOUBLING. ALSO IMPROVEMENTS IN THE CON.

page_text: TRUCTION OF THE SKEWERS FOR SHUTTLES AND WINDING MACHINES," upon the
condition (amongst others) that I, the said John Sidebottom, my executors
or administrators, by an instrument in writing under my, or their, or one of
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 Sidebottom, 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 follow-
ing statement (that is to say):-
My Invention has reference to certain improvements upon the Invention
secured to George James Wainwright and Charles Timothy Bradbury by
Letters Patent bearing date the Eighteenth day of July One thousand eight
hundred and fifty-seven, No. 1992, and it consists in making the partial cop
tubes, described in the Specification of the said Letters Patent (such partial
tubes being tubes with a slit or opening made in one side) of a suitable
conical form instead of cylindrical as heretofore customary, and in providing
apparatus for or means of holding the said conical partial tubes in a con-
centric position upon the spindles of mules for spinning and doubling;
part of
my Invention is also partly applicable to conical cop tubes, which
are not slit so as to form what are called above partial tubes.
My improvements in the construction of the skewers for shuttles and
winding machines consist in making them with a conical projection or
with a shoulder on which the conical tube or partial tube fits, and by which
it is held concentric with the skewer.
And in order that my Invention may be more fully understood and carried
into effect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 represents a conical partial cop tube constructed according to my
improvements; Fig. 2 is a plan of the same. On referring to these views it
will be seen that the edges of the slit or opening made in the side of the
partial cop tube are somewhat apart, and that the lower corners are rounded
off to facilitate the operation of swinging the partial tube on to the spindle
by the apparatus described in the Specification of Letters Patent granted
to me on the Sixteenth day of April One thousand eight hundred and fifty-
nine, No. 961, or by any other suitable combination of apparatus, the said
partial tubes being made of sheet metal of the requisite elasticity.

Fig. 3 shews one method which I employ for holding conical cop tubes in
concentric position on the spindles. In this view a is a conical partial tube,
and b, a flanged button or cop braid, which is loose on the spindle A, A, A,
The upper part of this button is of the same diameter as the interior of the
conical partial tube, and it rests upon the ring c, which is fast on the spindle.
When the lower end of the conical partial tube is on the flanged button b, as
shewn in the Drawing, it is held concentric with the spindle, and the cop is
built on the conical partial tube in the usual manner. The conical form of
the partial tube assists the building of the cop, as fewer stretches are required
to complete the cop bottom, and when the set of cops is complete the doffing
is effected by the attendants pushing the cops up the spindles by pressing
against the under side of the loose buttous or braids. The conical partial
tubes remain in the cops when they are doffed, while the buttons or braids drop
down the spindles upon the fast rings c, by which they are held in place
until the succeeding set of conical partial tubes are supplied to the spindles.
The flanged button or cop braid and the ring e may be also employed
when conical entire tubes are used instead of partial tubes, such tubes being
nade without a slit or opening in their side; they are made, by preference,
of sheet metal, and are placed over the ends of the spindles by hand or by
any of the known combinations of machinery now employed in putting ou
the paper or other tubes at present in use. The conical tubes, when placed
on the spindles, drop on to the loose buttons b, and the full cops are doffed
in the manner described in reference to the partial tubes.
Figs. 4, 5, 6, 7, and S shew another method employed by me for holding
conical cop tubes and partial tubes in a concentric position on their spindles,
which, on accounts of its simplicity and economy, I use by preference.
Fig. 4 represents an upright view, and Fig. 5, a plan of a conical partial
tube, the edge of which is bent in at the base or larger end, as shewn at e, d,
so as to fit on the spindle. This improved partial tube is sprung on the
spindle in the position shewn in Fig. 6 by the apparatus described in the
Specification of Letters l'atent above referred to, granted to me on the Six-
teenth day of April One thousand eight hundred and fifty-nine, No. 261, or
in my her
the proper cometic position
upon the spindle by means of the parts that are bent inwards without the
aid of the loose button b, above referred to, iu reference to Fig. 3; the fast
rings c are dispensed with, or left on, as may be found desirable.
Fig. 7 is a section, and Fig. 8, a plan of an entire conical сор tube con-
structed according to my improvements; in this ease also the edge is bent
inwards at the base or larger end of the tube, as in Figs. 4 and 5, to fit the

page_text: spindle. The cop tubes so constructed are intended to be put on the spindles
by dropping them over the points thereof in the same manner as the ordinary
paper or other cop tubes now known and in usc.
When the conical tubes or partial tubes described in reference to Figs. 1,
2, and 3 are employed, the skewers for shuttles and for winding machines
must be made with a conical projection or with a shoulder for the base of
the cone to fit upon, but when the conical partial tubes, shewn in Figs. 4
and 5, are used, the said conical projections or shoulders are not required;
but I make no claim to the employment of such skewers with such conical
projections or shoulders.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim,-
First, the uso of the improved cop tubes and partial tubes of a conical
form, as described and shewn in the Drawings, in connection with the appa-
ratus described and shewn in Fig. 3, for holing them in a concentric position
upon the spindles of mules for spinning and doubling.
Secondly, the improved conical cop tubes and partial tubes made as
described and shewn in Figures 4, 5, 6, 7, and S.
In witness whereof, I, the said John Sidebottom, have hereunto set my
hand and seal, this Fifteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-one.
JOHN SIDEBOTTOM. (L.6.)
