AN IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL TYRES
Year: 1863

page_text: LETTERS PATENT to Thomas Edward Vickers, of Sheffield, in the County
of York, Steel Manufacturer, for the Invention of "AN IMPROVEMENT IN
THE MANUFACTURE OF CAST-STEEL TYRES."-A communication from abroad
by Jacob Mayer, of Bochum, in the Kingdom of Prussia.
Scaled the 24th November 1863, and dated the 19th September 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Edward Vickers
at the Office of the Commissioners of Patents, with his Petition, on the
19th September 1863.
1, THOMAS EDWARD VICKERS, of Sheffield, in the County of York, Steel
Manufacturer, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL TYRES," to be as follows:-
Hitherto steel tyres when cast have been cast singly, each in a mould by
itself, thus involving considerable labour in the preparation of the moulds.
As an economic substitute for this plan it is now proposed to cast what may
be termed a cylinder presenting the profile of two or more tyres (by preference
six and upwards) piled one upon the other. This cylindrical casting is to be
divided up into tyres in a turning lathe, or by saws as may be found most
convenient, and the tyres may then be finished in the usual way.

by the said Thomas Edward Vickers in the Great Seal Patent Office on
the 19th March 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
EDWARD VICKERS, of Sheffield, in the County of York, Steel Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Edward Vickers, Her special license that I, 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 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 "AN IM-
PROVEMENT IN THE MANUFACTURE OF CAST-STEEL TYRES," being a communication
from abroad, upon the condition (amongst others, that I, the said Thomas
Edward Vickers, by an instrument in writing under my hand and seal, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Edward Vickers, 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):-
The object of this Invention is to effect a material economy in the manu-
facture of cast steel tyres by the introduction of a novel mode of moulding and
casting such articles. Hitherto steel tyres when cast have been moulded
and cast singly, thus involving considerable manual labor in the preparation
of the moulds when a large number of tyres are required to be cast. In place
of employing this mode of moulding and casting the tyres, I prepare a pattern
which may be described as a cylinder composed of a series of patterns of tyres
(I prefer six) placed side by side or piled one upon the other, and secured
firmly together. With the use of this compound pattern I form a compound

page_text: mould in loam in the usual or any approved manner of moulding, and I obtain
by the operation of casting a counterpart thereof in cast steel.
In the accompanying Drawing I have shown in front view at Fig. 1, and in
cross section at Fig. 2, a casting produced in the manner described, which
casting is intended to form six tyres, but more or a less number may be obtained
at one casting if thought desirable. When the cylindrical casting is removed
from the mould it' is chucked and turned in a lathe and then divided up in the
direction of the red lines of Fig. 2 to separate the tyres. Or the casting may be
divided by rotary saws and the turning and facing up of the tyres in the lathe
afterwards effected.
Having now set forth the nature of the Invention of "An Improvement in
the Manufacture of Cast-steel Tyres," and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part recited
Letters Patent I claim manufacturing cast-steel tyres with the aid of compound
moulds in the manner and for the purpose above described.
In witness whereof, I, the said Thomas Edward Vickers, have hereunto
set my hand and seal, this Sixteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-four.
Witness,
CHARLES F. BIELANSKI,
of 211, Burngreave Road,
Sheffield.
