Year: 1869

page_text: LETTERS PATENT to John Octavius Butler, of Leeds, in the County
of York, Engineer, Joseph Nichols, of the same Place, Engineer,
and William Heslop, of Doncaster, in the County of York,
Engineer, for the Invention of “IMPROVEMENTS IN THE MANUFACTURE
PROVISIONAL SPECIFICATION left by the said John Octavius Butler,
Joseph Nichols, and William Heslop at the Office of the Com-
missioners of Patents, with their Petition, on the 30th December
1869.
We, JOHN OCTAVIUS BUTLER, of Leeds, in the County of York,
Engineer, JOSEPH NICHOLS, of the same Place, Engineer, and WILLIAM
HESLOP, of Doncaster, in the County of York, Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF TYRES AND HOOPS FOR RAILWAY WHEELS AND OTHER PURPOSES,"
to be as follows:-
In performing our Invention we employ a mould in which is a recess
of the shape of the hoop or tyre to be produced, and a die fitting into

page_text: the said mould. A hoop of iron, steel, or other metal of the required
size and diameter is heated to a welding heat and placed in the recess in
the mould, the dic is then placed over the mould and subjected to
hydraulic or other pressure or to the action of a steam hammer; the
heated metal is thus forced into every portion of the recess in the mould t
and a perfect tyre or hoop is formed. In preparing the hoop to be
moulded as above described we stamp a hole in a disc of metal, and then
enlarge the rough hoop so formed by hammering over an anvil horn, or
otherwise, or we make the hoop of a bar or plate of iron or steel bent and
welded. When the tyre or hoop is made of steel we cast a hoop of the
required size, and place it when hot in the mould, and operate as in
making wrought iron or steel tyres and hoops. By this means tyres for
railway and other wheels and hoops for hooping the cylinders of
hydraulic presses and other purposes can be made without rolling.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said John Octavius Butler, Joseph Nichols, and
William Heslop in the Great Seal Patent Office on the 30th June
1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
OCTAVIUS BUTLER, of Leeds, in the County of York, Engineer, JOSEPH
NICHOLS, of the same Place, Engineer, and WILLIAM HESLOP, of
Doncaster, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of December, 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 us, the said John Octavius Butler, Joseph Nichols, and
William Heslop, Her special licence that we, the said John Octavius
Butler, Joseph Nichols, and William Heslop, our executors, adminis-
trators, and assigns, or such others as we, the said John Octavius Butler, 1
Joseph Nichols, and William Heslop, 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,

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE
OF TYRES AND HOOPS FOR RAILWAY WHEELS AND OTHER PURPOSES," upon the
condition (amongst others) that we, the said John Octavius Butler,
Joseph Nichols, and William Heslop, 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 per-
formed, 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 John Octavius Butler, Joseph
Nichols, and William Heslop, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
(that is to say) :-
In performing our Invention we employ a mould in which is a recess
of the shape of part of the hoop or tyre to be produced and a die fitting
into the said mould. A hoop of iron, steel, or other metal of the
required size and diameter is heated to a welding heat and placed in the
recess in the mould, the die is then placed over the mould and subjected
to hydraulic or other pressure or to the action of a steam hammer; the
heated metal is thus forced in every portion of the recess in the mould
and a perfect tyre or hoop is formed. In preparing the hoop to be
moulded, as above described, we stamp a hole in a disc of metal, and then
enlarge the rough hoop so formed by hammering over an anvil horn, or
otherwise, or we make the hoop of a bar or plate of iron or steel or
other metal bent and welded. When the tyre or hoop is made of steel
or other metal we cast a hoop of the required size and place it when
hot in the mould and operate as in making wrought iron or steel tyres.
and hoops.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is a section of a mould and die suitable for making tyres for
railway wheels; and Fig. 2. is a plan of the mould with the die removed.
The mould consists of a heavy block of cast iron or other metallic
material marked a, the upper part of which is strengthened by a wrought-

page_text: iron hoop b, which is shrunk on when hot. In the upper face of the
mould is a circular recess to receive and guide the lower part of the
die c, which is also made of cast iron or other metallic material. The
upper surface of the mould and the under surface of the die when put
together leave a space of the shape of the tyre or hoop to be manu-
factured, and the tyre or hoop is raised out of the mould by four or other
convenient numbers of levers f; which move on the fulcrum studs g and
act on the sliding blocks / fitting in holes in the mould. The levers fare
inserted in slots i cast or formed in the body of the mould, or the
blocks / acting on the tyre or hoop may be raised so as to lift the tyre
or hoop out of the mould by a series of hydraulic rams and cylinders, or
screws or eccentrics may be applied for that purpose.
The mode of operation is as follows:-The die c having been lifted off
the mould a hoop of iron, steel, or other metal of about the weight of
the type or hoop to be made or of the required size and heated to a
welding heat is laid in the mould and the die is brought into contact
with it; the mould and die are then forced together either by steam,
hydraulic, or other pressure, or by the repeated blows of a powerful
hammer; the heated metal is thus forced into every portion of the spaces
between the mould and die to form the tyre or hoop. As soon as the
tyre or hoop has been formed the die is lifted off, and the tyre or hoop
is loosened in the mould by the appliances described and removed. In
preparing the hoop to be moulded, as above described, we stamp a hole
in a disc of metal, and then enlarge the rough hoop so formed by
hammering over an anvil horn, or otherwise; or we make the hoop of a
bar or plate of iron or steel or other metal bent and welded. When the
tyre is made of steel or other metallic material we either cast a hoop
of the required size and place it when hot in the mould and operate as
above described, or we make a mould of the shape shewn in Fig. 3, and
run the molten steel or other metallic material into the groove in the
mould, and then compress or consolidate the steel or other metallic
material by bringing the die on to the molten metal in the mould.
By means of the improvements above described tyres and hoops of
every description may be made without rolling or they can be finished
by rolling if desirable.
Having thus stated the nature of our Invention and described the
manner of carrying the same into operation, we wish it to be understood
that we do not intend to limit ourselves to the details given, and that

page_text: what we claim is, the manufacture of tyres and hoops by compressing
highly heated metal or steel in a fluid state between a mould and
a die,
In witness whereof, we, the said John Octavius Butler, Joseph
Nichols, and William Heslop, have hereto set our hands and
seals, this Twenty-eighth day of June One thousand eight
hundred and seventy.
