IMPROVEMENTS IN THE MANUFACTURE OF WHEEL TYRES
Year: 1864

page_text: LETTERS PATENT to Joseph Whitley, of Leeds, in the County of York,
Brassfounder, and David Farrar Bower, of Hunslet, in the same County,
Chemist, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
WHEEL TYRES."
Sealed the 25th November 1864, and dated the 27th May 1864.
PROVISIONAL SPECIFICATION left by the said Joseph Whitley and
David Farrar Bower at the Office of the Commissioners of Patents, with
their Petition, on the 27th May 1864.
We, JOSEPH WHITLEY, of Leeds, in the County of York, Brassfounder,
and DAVID FARRAR BOWER, of Hunslet, in the same County, Chemist, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF WHEEL TYRES," to be as follows:-
Our Invention consists in forming wheel tyres by the aid of centrifugal
force, as hereafter described. . We take a mould and cause it to revolve, and
while revolving we force or cause to flow into it cast steel or other metal.
In making cast steel tyres, we pour the cast steel into the mould while
revolving, and the steel forms itself into a rim or tyre of the form indicated
by the mould. In making malleable iron tyres, that is to say, wrought-iron
tyres, we take the ball or bloom from the furnace, and force the same while in

page_text: a molten or plastic state into the revolving mould; the metal will thus assume
the form indicated by the mould. The rims or tyres produced, as before
described, if not of the finished or desired size, may be re-heated, and then
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Whitley and David Farrar Bower in the Great
Seal Patent Office on the 26th November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
WHITLEY, of Leeds, in the County of York, Brassfounder, and DAVID
FARRAR BOWER, of Hunslet, in the same County, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Joseph Whitley and David Farrar Bower, Her special licence
that we, the said Joseph Whitley and David Farrar Bower, our exe-
cutors, administrators, and assigns, or such others as we, the said
Joseph Whitley and David Farrar Bower, our 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 "IMPROVEMENTS IN THE MANUFACTURE OF WHEEL TYRES," upon
the condition (amongst others) that we, the said Joseph Whitley and David
Farrar Bower, or one of us, our executors or administrators, by an instrument
in writing under our, or their, or one of our or 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 we, the said Josephi Whitley and David Farrar
Bower, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
Our Invention consists in forming wheel tyres by the aid of centrifugal

page_text: force, as hereafter described.
We take a mould and cause it to revolve, and
while revolving we force or cause to flow into it cast steel or other metal.
In making cast steel tyres we pour the cast steel into the mould while
revolving, and the steel forms itself into a rim or tyre of the form indicated
by the mould. In making malleable iron tyres, that is to say, wrought-iron
tyres, we take the ball or bloom from the furnace, and force the same while
in a molten or plastic state into the revolving mould; the metal will thus
assume the form indicated by the mould. The rims or tyres produced, as
before described, if not of the finished or desired size, may be reheated, and
then hammered, rolled, or pressed out to the proper size.
Figure 1 is an external elevation, and Figure 2 a view, partly in section,
of the machinery we prefer to employ in the manufacture of our wheel
tyres.
A is a metal mould lined with loam or loam wash recessed to form the
flange of the tyre; this mould is fixed on a spindle B; C is a feed spout
through which the molten metal is run into the mould; D, E, are fast and
loose pulleys for imparting rotary motion to the mould; or motion may be
imparted through bevel gear driven by a pulley on a horizontal shaft F.
Although we have shown the mould as made to revolve horizontally, we
do not confine ourselves thereto, as the mould may be made to revolve
vertically.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim manufacturing
wheel tyres by the aid of centrifugal force, substantially in manner herein-
before described.
In witness whereof, I, the said Joseph Whitley, for myself and on
behalf of the said David Farrar Bower, have hereunto set my hand
and seal, this Twenty-third day of November, One thousand eight
hundred and sixty-four.
JOSEPH WHITLEY.
