IMPROVEMENTS IN CASTING HOOPS OF STEEL SUITABLE FOR MAKING TYRES
Year: 1865

page_text: LETTERS PATENT to William Daniel Allen, of Sheffield, in the County
of York, Steel Manufacturer, for the Invention of "IMPROVEMENTS IN
CASTING HOOPS OF STEEL SUITABLE FOR MAKING TYRES."
Sealed the 1st May 1866, and dated the 8th November 1865,
PROVISIONAL SPECIFICATION left by the said William Daniel Allen at
the Office of the Commissioners of Patents, with his Petition, on the
8th November 1865.
J, WILLIAM DANIEL ALLEN, of Sheffield, in the County of York, Steel
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CASTING HOOPS OF STEEL SUITABLE FOR MAKING TYRES," to be
as follows:-
This Invention has for its object improvements in casting hoops of steel
suitable for making tyres. In casting such hoops it has been usual to
make each mould with a separate get or runner; the arrangement is very
inconvenient when large charges of melted steel, such as are prepared by
the Bessemer process, have to be cast into such hoops.
Now according to my Invention I arrange one get or runner to supply
two or a greater number of moulds. It is convenient to place the moulds
concentrically one over the other, and to have a suitable core passing down
[Price 8d.]

page_text: through the centre of the set; the get or runner may pass down through
this core, and lateral openings may be made from it into each of the
moulds; or the steel may be may be conducted by one get or runner into the
bottom mould only, and be allowed to pass from thence into the other
moulds by holes provided for the purpose, either in the plates or covers
which separate the castings, or by passages in the core communicating from
one mould to the other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Daniel Allen in the Great Seal Patent Office on
the 8th May 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DANIEL ALLEN, of Sheffield, in the County of York, Steel Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, hearing date the Eighth day of November, in the year
of
our Lord One thousand eight hundred and sixty-five, in the twenty-ninth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Daniel Allen, Her special licence that I, the
said William Daniel Allen, my executors, administrators, and assigns, or such
others as I, the said William Daniel Allen, 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 "IMPROVEMENTS IN CASTING HOOPS OF STEEL SUITABLE FOR MAKING
TYBES," upon the condition (amongst others) that I, the said William
Daniel Allen, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Daniel Allen, 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 thereof, that is to say:-

page_text: This Invention has for its object improvements in casting hoops of steel
suitable for making tyres. In casting such hoops it has been usual to
make each mould with a separate get or runner; this arrangement is very
inconvenient when large charges of melted steel, such as are prepared by
the Bessemer process, have to be cast into such hoops.
Now according to my Invention I arrange one get or runner to supply
two or a greater number of moulds, it is convenient to place the moulds
concentrically one over the other and to have a suitable core passing down
through the centre of the set; the get or runner may pass down through
this core, and lateral openings may be made from it into each of the
moulds; or the steel may be conducted by one get or runner into the
bottom mould only, and be allowed to pass from thence into the other
moulds by holes provided for the purpose, either in the plates or covers
which separate the castings, or by passages in the core communicating from
one mould to the other.
Having thus stated the nature of my Invention I will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing represents a vertical section of three moulds, one above the
other, which are supplied by one get or runner. A, A, A, are the cylindrical
parts of the moulds; B, B, B, B, are plates forming bottoms and covers to
the moulds, the two centre plates are each made in two halves to facilitate
the removal of the castings; D is the central core, and down this the get
or runner E is shown to pass, having from it lateral openings F com-
municating with each of the moulds, the lateral openings leading into the
two upper moulds should be made inclined, as shewn, in order to prevent
the metal running that way until after the bottom mould is full.
I do not confine my Invention to the precise arrangement I have
described as it will be obvious that the object desired may be readily
accomplished in other similar ways; for instance, instead of running the
steel down the core a properly arranged passage or get may be made
outside the moulds, communicating to each mould by lateral passages, or
the steel may be conducted by one get or runner into the bottom mould
only and be allowed to pass from thence into the other moulds by holes
provided for that purpose, either in the plates or covers which separate the
castings, or by passages in the core communicating from one mould to
the other; but my Invention is supplying by one get or runner two or

page_text: a greater number of moulds in which hoops of steel suitable for making
tyres are cast in order to save waste of metal and to facilitate the casting
operation. The moulds in other respects are inade as heretofore.
In witness whereof, I, the said William Daniel Allen, have hereunto
set my hand and seal, this Fourth day of May, in the year of our
Lord One thousand eight hundred and sixty-six.
W. D. ALLEN. (L.S.)
