page_text: LETTERS PATENT to John Sidebottom, of Harewood, near Mottram, in
the County of Chester, Cotton Spinner and Manufacturer, for the Inven-
tion of "CERTAIN IMPROVEMENTS IN MACHINERY FOR MAKING PARTIAL TUBES
PROVISIONAL SPECIFICATION left by the said John Sidebottom at the
Office of the Commissioners of Patents, with his Petition, on the 26th
October 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 "CERTAIN IMPROVEMENTS IN MACHINERY FOR MAKING PARTIAL
TUBES FOR THE SPINDLES OF SPINNING AND OTHER MACHINES," to be as follows:-
My improvements in machinery for making partial tubes is applicable to
those partial tubes that are made of sheet metal and of a conical shape, as
described in the Provisional Specification of Letters Patent applied for by
me on the Twentieth of May, One thousand eight hundred and sixty-one,
No. 1282. The object being to bend the sheet metal forming the base of the
said partial tubes inwards to fit the spindles or skewers on which they are to
be placed.

page_text: In performing my Invention, the larger end of the cone is provided with
notches, and the metal between the notches is first bent partly inwards by a
cup-shaped punch. After this preliminary operation the final bending inwards
of the metal is performed by another punch working within the cup-shaped
one, of the size of the spindle or skewer on which the partial tube is to be
placed. A die is inserted into the open end of the partial tube for giving the
requisite inward bend to the sheet metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Sidebottom in the Great Seal Patent Office on the
26th April 1862.
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 Twenty-sixth day of October, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Sidebottom, Her special license that I, the said John
Sidebottom, my executors, administrators, and assigns, or such others as I,
the said John Sidebottom, 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 Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY FOR MAKING PARTIAL TUBES FOR THE SPINDLES OF
SPINNING AND OTHER MACHINES," upon the condition (amongst others) that I,
the said John Sidebottom, my executors or administrators, by an instrument
in writing under or their, or one of their hands and seals, should parti-
cularly 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 per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-

page_text: My improvements are applicable to those partial tubes that are made of
-sheet metal and of a conical shape, as described in the Specification of Letters
Patent, granted to me on the Twentieth day of May, One thousand eight
hundred and sixty-one, Number 1282, the object being to bend the sheet
metal forming the base of the said partial tubes inwards, to fit the spindles or
-skewers on which they are to be placed.
In performing my Invention, the larger end of the cone is provided with
notches, and the metal between the notches is first bent partly inwards by
cup-shaped punch. After this preliminary operation the final bending inwards
of the metal is performed by another punch working within the cup-shaped
one, of the size of the spindle or skewer on which the partial tube is to be
placed. A die is inserted into the open end of the partial tube for giving the
requisite inward bend to the sheet metal.
And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation, and Fig. 2, a plan of my improved machinery. a is
the stand or framework of the machine; b is a square or other shaped spindle,
which slides up and down in the frame a, being held in its place by the cap c;
to the upper end of the spindle 6 is connected the bar d, which slides in the
top part of the frame a, and in which is a slot for the lever e to pass through;
this lever vibrates upon the fulcrum f, and to the shorter arm of the lever is
jointed the upper end of the rod g, the lower end being connected to the
treadle h. To the lower end of the spindle 6 is attached the stud i, shewn
detached in section in Fig. 3; the bottom of the stud i forms the cup-shaped
punch j, and through it passes the centre punch k, which is looped above for
the lever to pass through; this lever is hinged to the fulcrum m, which is
fixed to the stud i; the object of the lever is to press the centre punch k
downwards when required; it is raised again by the spring n, which is attached
to the stud i. The catch lever n¹ is hinged to the cap c, and provided above
with a catch fitting a notch in the upper end of the spindle b. On the bed
plate of the stand a is placed the die box o, within which the die
P, shewn
detached in Figs. 3 and 4, is held; this die can easily be removed and another
put in its place when required. The mode of operation is as follows:-The
partial tubes, which are made by preference of sheet steel, are first bent into
the form of a cone, as shewn in Fig. 5, the larger end of the cone being pro-
vided with notches; these partial tubes are then placed in the die p, with the
notches projecting above the top of the die, as shewn in Fig. 1, and the slot
of the partial tube fitting on the rib p', which is fixed in the die; the operator'

page_text: then places the instrument or die q, shewn detached in Fig. 4, in the open
end of the partial tube, and the treadle h, which is held down during the
operations of placing the partial tube in the die p, and putting the instru-
ment in its place, is then liberated by the operator, thus releasing the
spindle b, which in dropping brings the cup-shaped punch ; on to the notches
of the partial tube, and flattens them over the instrument 93 the operator
then presses on the lever 1 to bring down the lower end of the centre punch k
into the opening in the instrument q, thereby bending the notches of the
parţial tube inwards; the operation of pressing down the lever / causes the
upper end of the catch lever n¹ to hook on the notch in the spindle b, thus
preventing the spindle from rising when the centre punch k is bending the
notches of the partial tube over. the instrument q.
As soon as the operator
releases the lever l, the spring n raises it again, the treadle his pressed down
as soon as the centre punch k has performed its duty, and when the spindle b
is raised, the operator by means of the instrument 9 draws the partial tube
out of the die p, and then slips it off the instrument q, which
then at liberty
for the next operation. It will be apparent that the size of the centre punch k
must correspond with the size of the spindle or skewer on to which the partial
cop tube is to be placed when in use, and that consequently the punches j
and k, and the die p must be capable of being easily taken out of the machine
and replaced by others of different sizes, to correspond with the various sizes
of the spindles or skewers required. I would also remark that the mechanism
for actuating the punches may be considerably varied or modified, and that
the ordinary screw fly press may be employed.
Having thus stated the nature of my Invention, and described a convenient
arrangement of machinery for carrying the same into operation, I declare that
I claim the machinery shewn and described, or any modification of such
machinery, for bending inwards the larger end of the cop tubes for the
purpose of causing them to fit the spindles or skewers of spinning and other
machines.
In witness whereof, I, the said John Sidebottom, have hereto set my hand
and seal, this Twenty-third day of April, in the year of our Lord One
thousand eight hundred and sixty-two.
JOHN SIDEBOTTOM. (L.S.)
