PROVISIONAL SPECIFICATION left by the said Thomas Edward Vickers
at the Office of the Commissioners of Patents, with his Petition, on
the 4th January 1866.
I, THOMAS EDWARD VICKERS, of Sheffield, in the County of York,
Steel Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS..IN MACHINERY FOR ROLLING HOOPS OR TYEES FOR WHEELS OR
OTHER PURPOSES," to be as follows:-
My Invention of "Improvements in Machinery for Rolling Hoops or
Tyres for Wheels or other Purposes" consists in so arranging a rolling
mill that the parts of the rolls between which the work is performed arc
made to overhang their bearings, and the remaining parts of the rolls,
instead of being placed side by side or one above the other, as is usual,
are extended in opposite directions, so that the hoop to be rolled or the
Price Sd.]

page_text: work to be performed may be placed and confined between collars or
flanges, of which only one is upon each roll, and which flange from its
position may pass if required up to or beyond the centre of the other roll.
The face of each flange or collar is at the same time in contact with the
end of the opposite roll, thus enabling the working part of the rolls, or of
one of them, to be made of small diameter so as to be capable of operating
upen a hoop having a small hole, say of only six or eight inches diameter,
in the centre and having the outside diameter much greater; say three or
four times as much. As all the work is performed between the collars or
One of
flanges on the rolls, all undue lateral spreading will be prevented.
the rolls is to be made movable by hydraulic power or by screws or other
known means, in order to effect the compression of the metal whilst
rolling and to enable the hoops to be put on or taken off the roll.
The Invention also consists in applying driving power separately and
independently to each roll, so that each may be driven at its proper speed
in proportion to its diameter and to the varying difference between the
internal and external diameters of the tyre or hoop being operated upon.
As in the improved rolling mill the driving ends of the rolls project from
opposite sides of the machine, this separate driving of the rolls can be
effected without difficulty or complication of parts.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Edward Vickers in the Great Seal Patent Office
on the 4th July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
EDWARD VICKERS, of Sheffield, in the County of York, Steel Manufac-
turer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of January. in the year of our
Lord One thousand eight hundred and sixty-six, in the twenty-ninth
year of Her reign. did, for Herself, Her heirs and successors, give and
grant unto me, the said Thomas Edward Vickers. Her special licence that
1, the said Thomas Edward Vickers, my executors, administrators, and
assigns, or such others as I, the said Thomas Edward Vickers, my
executors, administrators, and assigns, should at any time agree with, and

page_text: 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 Cnited Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
FOR ROLLING HOOPS OR TYRES FOR WHEELS OR OTHER PURPOSES." upon the con-
dition (amongst others) that I, the said Thomas Edward Vickers, 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 Thomas Edward Vickers, 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, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
My Invention of "Improvements in Machinery for Rolling Hoops or
Tyres for Wheels or other Purposes" consists in so arranging a rolling mill
that the parts of the rolls between which the work is performed are made
to overhang their bearings, and the remaining parts of the rolls, instead of
being placed side by side or one above the other, as is usual, are extended
in opposite directions, so that the hoop to be rolled or the work to be per-
formed may be placed and confined between collars or flanches, of which
only one is upon each roll, and which flanch from its position may pass if
required up to or beyond the centre of the other roll.
In the accompanying Drawing Fig. 1 is a plan view, and Fig. 2 a sectional
clevation of one of my improved machines constructed for rolling hoops or
tyres for railway wheels.
A is the roll intended to operate on the inside of the tyre or hoop, and
is called the inner roll, and is provided with a fanch A"; B is another roll
for rolling or forming the outside or periphery of the tyre; this is also
provided with a flanch B. The face of each of the flanches or collars A"
and B are so arranged that when at work they are at the same time ir
contact with the end of the opposite roll, that is to say, the flauch A" is in
contact with the end of the roll B, and the flanch B is in contact with the
end of the roll A, thus enabling the working part of the rolls or of one of
them, such as the roll A, to be made of small diameter so as to be capable

page_text: of operating upon a hoop having a small hole, say of only six or eight
inches diameter in the centre, and having the outside diameter much
greater, say three or four times as much. As all the work is performed
between the collars or flanches A and B of the rolls A and B, all undue
lateral spreading of the tyre will be prevented. One of the rolls is to be
made moveable by hydraulic power or by screws or other known means, in
order to effect the compression of the metal whilst rolling, and to enable
the hoops to be put on or taken off the inner roll. In the Drawing the
roll B is shewn as turning in bearings attached to the moveable carriage C,
which is capable of being raised and lowered by the ram G of the hydraulic
cylinder F, and thus may be raised and lowered so as to give the tyre or
hoop the required pressure and allow it to be put on or taken off the inner
roll. The upper part of the carriage C is steadied by guides fixed in the
framing D. It will now be understood that if the several parts be in the
position shewn in Fig. 2, a rough hoop for a railway tyre when heated may
be placed on the roll A, and then by pumping water into the cylinder F,
the ram G and with it the carriage C and outer roll B will be raised and
the latter brought up and made to bear against the outer periphery of the
hoop or tyre, and by compressing it between the two rolls A and B the
tyre will be rolled into the required form.
The Invention also consists in applying driving power separately and
independently to the rolls A and B, so that each of these latter may be
driven at its proper speed in proportion to its diameter and to the varying
difference between the internal and external diameters of the tyre or hoop
which is being operated upon. As in the improved rolling mill the driving
ends of the rolls project from opposite sides of the machine, this separate
driving of the rolls can be effected without difficulty or complication of
parts. The mode of actuating the working rolls in machinery of this kind
is so well known that I have not thought it necessary to shew the gearing
in the Drawing, nor to give any detailed description of it, as it need not
differ in principle or construction from the toothed gearing usually employed
for analogous purposes.
Having now described my Invention of "Improvements in Machinery
for Rolling Hoops or Tyres for Wheels or other Purposes," and having
explained the manner of carrying the same into effect, I claim as the
Invention secured to me by Letters Patent as aforesaid, the mode herein
set forth of constructing and arranging the rolls between which the hoop
or tyre to be operated upon is placed.

page_text: Secondly, I claim applying driving power separately and independently
to each roll, so that each roll may be driven at its proper speed, as herein
set forth.
In witness whereof, I, the said Thomas Edward Vickers, have here-
unto set my hand and scal, the 22nd day of June, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
WM. WHITEHEAD.
