page_text: LETTERS PATENT to John Windle, of Sheffield, in the County of

HOOPS OR TYRES OF IRON OR STEEL."

PROVISIONAL SPECIFICATION left by the said John Windle at
the Office of the Commissioners of Patents, with his Petition, on
the 27th July 1869.
I, JOHN WINDLE, of Sheffield, in the County of York, Tyre Roller,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN ROLLING HOOPS OR TYRES OF IRON OR STEEL," to be as follows:-
My Invention relates to improvements in rolling weldless hoops or
tyres of iron or steel.
Hitherto when rolling weldless tyres of iron or steel webs or fins
have been formed at the edges of the tyre by reason of the metal
spreading during the process of rolling between the ends of one roll and
the flanges of the other. These webs or fins by reason of their com-
paratively small substance, and the water which is thrown upon the

page_text: hoop or tyre as the rolling proceeds become cooled before the rolling is
completed, and are apt to become wedged in and to cut and wear the
rolls. The webs or fins formed when rolling a hoop or tyre as above
described must be subsequently cut off, thus entailing a certain amount
of waste labor and expense.
Now according to my Invention I employ a subsidiary roll or rolls in
addition to the rolls hitherto employed for rolling weldless hoops or
tyres from iron or steel, and I so mount and work such subsidiary roll
or rolls that as the weldless hoop or tyre travels round and passes from
between the main rolls any webs or fins formed or partly formed by such
main rolls are at once rolled down by means of the subsidiary roll or
rolls into the body of the metal forming the hoop or tyre. By the use
of the subsidiary roll or rolls according to my Invention any metal
spread at the edges of the hoop or tyre is at once closed into the body of
the hoop or tyre, and is not spread out into webs or fins, thus reducing
the wear of the rolls, and saving the labor and waste of subsequent
trimming. The subsidiary roll or rolls are mounted in suitable frames
capable of adjustment by a screw or other suitable mechanical means in
place of the subsidiary roll or rolls. A cutter or cutters may be
mounted according to my Invention so as to remove the web or
fin as it is formed in the operation of rolling.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Windle in the Great Seal Patent Office on
the 25th January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WINDLE, of Sheffield, in the County of York, Tyre Roller, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of July, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Windle, Her special licence
that I, the said John Windle, my executors, administrators, and
assigns, or such others as I, the said John Windle, executors,
administrators, and assigns, should at any time agree with, and no

page_text: 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 ROLLING HOOPS OR TYRES OF IRON OR STEEL," upon the condition (amongst
others) that I, the said John Windle, 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 Windle, do hereby declare
the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say) :-
:-
My Invention relates to improvements in rolling weldless hoops or
tyres of iron or steel; and in order that my Invention may be fully
understood and readily carried into practice, I will proceed to describe
the same, reference being had to the Drawings hereunto annexed.
Hitherto when rolling weldless tyres of iron or steel webs or fins have
been formed at the edges of the tyre by reason of the metal spreading
during the process of rolling between the ends of one roll and the flanges
of the other.
At Figure 1 of the Drawing I have shewn in section a tyre where such
webs or fins a, a, have been formed in the process of rolling. These
webs or fins by reason of their comparatively small substance and the
water which is thrown upon the hoop or tyre as the rolling proceeds
become cooled before the rolling is completed, and are apt to become
wedged in and to cut and wear the rolls. The webs or fins formed when
rolling a hoop or tyre, as above described, must be subsequently cut off,
thus entailing a certain amount of waste labour and expense.
Now according to my Invention I employ a subsidiary roll or rolls
within the tyre in addition to the rolls hitherto employed for rolling
weldless hoops or tyres from iron or steel, and I so mount and work

page_text: such subsidiary roll or rolls that as the weldless hoop or tyre travels
round and passes from between the main rolls any webs or fins formed
or partly formed by such main rolls are at once rolled down by means of
the subsidiary roll or rolls into the body of the metal forming the hoop
or tyre. By the use of the subsidiary roll or rolls according to my
Invention any metal spread at the edges of the hoop or tyre is at once
closed into the body of the hoop or tyre, and is not spread out into webs
or fins, thus reducing the wear of the rolls and saving the labour and
waste of subsequent trimming. A tyre is shewn in section at Figure 2
of the Drawings in which the fins or webs have been rolled into the body
of the tyre according to my Invention, the interior of the tyre being thus
formed without the webs or fins shewn in Figure 1. The subsidiary
roll or rolls are mounted in suitable frames capable of adjustment by
a screw or other suitable mechanical means.
Figure 3 of the Drawings shews a side view and Figure 4 a hori-
zontal section of so much of a machine for rolling weldless tyres
having my Invention applied thereto as will enable me to explain the
same.
b and c are the main rolls for rolling the weldless tyre, as is well
understood, being the roll without flanges within the tyre, and c the
exterior flanged roll, which in the process of rolling has hitherto been
allowed to form webs or fins in the interior of the tyre, as herein-before
described; d is the tyre in process of being rolled; e is the subsidiary
roll acting according to my Invention within the tyre to counteract the
tendency of the flanged roll c to form webs or fins. The roll e revolves
in suitable bearings in the frame e¹, the position of which is capable of
adjustment by means of the screw e³, bevilled wheels e³, and hand
wheel e*. After the rolling of the tyre, and when necessary to remove it
from the rolls, the hand lever e³ is caused to move the roll e endwise
from its bearings, and so permit of the removal of the tyre.
Having now described the nature of my Invention, and means
whereby the same may be carried into operation, I would have it under-
stood that I do not confine myself to the precise means herein-before
described for carrying my Invention into practice, and that several of
such rolls e may be employed if desired to act within the tyre, and the
mechanical arrangement employed for mounting and actuating such
rolls may be greatly varied without departing from the nature of my
Invention.

page_text: And I would further remark that in place of the subsidiary roll or
rolls e a cutter or cutters may be mounted in accordance with my
Invention so as to remove the web or fin as it is formed in the operation
of rolling.
What I claim as my Invention is, the rolling down or otherwise
removing of the webs or fins formed when rolling weldless tyres by
means of a subsidiary roll or rolls, or their equivalents, acting within
the tyre as the rolling proceeds, substantially as and for the purposes
herein-before described.
In witness whereof, I, the said John Windle, have hereunto set my
hand and seal, this Twenty-first day of January, in the year of
our Lord One thousand eight hundred and seventy.
JOHN WINDLE. (L.S.)
