IMPROVEMENTS IN APPARATUS EMPLOYED IN FORGING TYRES, HOOPS, AND RINGS
Year: 1875

page_text: LETTERS PATENT to William Hassalwood Carmont, of Fairfield, in
the County of Lancaster, Iron Manufacturer, for the Invention
of "IMPROVEMENTS IN APPARATUS EMPLOYED IN FORGING TYRES, HOOPS, AND
RINGS."
Sealed the 21st August 1875, and dated the 2nd July 1875.
PROVISIONAL SPECIFICATION left by the said William Hassalwood
Carmont at the Office of the Commissioners of Patents, with his
Petition, on the 2nd July 1875.
I, WILLIAM HASSALWOOD CARMONT, of Fairfield, in the County of
Lancaster, Iron Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS EMPLOYED IN FORGING TYRES,
HOOPS, AND RINGS," to be as follows:-
My Invention consists in an improved mode of constructing the
mould in which tyres, hoops, or rings are forged. The mould consists
of a loose block of cast steel or other metal fitting on the anvil, the
inside of the block being made of the shape of the article required;

page_text: the outside of the loose block is or may be strengthened by means of
a hoop of steel or iron. The mould can easily be removed from the
anvil and a larger or smaller one put in its place. The hammer face
can be made large enough to act on the whole surface of the tyres,
hoops, or rings, or it may be made narrow so as to act by a succession of
blows as the mould is turned slowly round.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Hassalwood Carmont in the Great Seal
Patent Office on the 22nd November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HASSALWOOD CARMONT, of Fairfield, in the County of Lancaster, Iron
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of July, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Hassalwood Carmont, Her special
licence, that I, the said William Hassalwood Carmont, my executors,
administrators, and assigns, or such others as I, the said William
Hassalwood Carmont, 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 APPARATUS EMPLOYED IN FORGING TYRES, HOOPS, AND S
RINGS," upon the condition (amongst others) that I, the said William
Hassalwood Carmont, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause a
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 William Hassalwood Carmont, do

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say) :-
"
My Invention consists in an improved mode of constructing the
mould in which tyres, hoops, or rings are forged. The mould consists
of a loose block of cast steel or other metal, fitting on the anvil, the
inside of the block being made of the shape of the article required;
the outside of the loose block is or may be strengthened by means of a
hoop of steel or iron. The mould can easily be removed from the anvil
and a larger or smaller one put in its place. The hammer face can be
made large enough to act on the whole surface of the tyres, hoops,
or rings, or it may be made narrow so as to act by a succession of blows
as the mould is turned slowly round.
יו
And in order that my Invention may be fully understood and
readily carried into operation, I will proceed to describe the accom-
panying Sheet of Drawings, reference being had to the figures and letters
marked thereon.
Fig. 1 is an elevation, partly in section, of my improved apparatus for
forging tyres, hoops, and rings.
Fig. 2 is a plan of the hammer head turned with the face upwards.
.
Fig. 3 'is a plan of the mould block, and Fig. 4 is a section of the
blank to be converted into a tyre, hoop, or ring.
a is the anvil block; b, the anvil; and c, the hammer, which is con-
nected 'in the usual manner to the piston of a steam hammer or to the
ram of a hydraulic press; d is the loose mould made of cast steel or
other metal, fitting easily on a projection formed on the top of the
anvil b, the inside of the mould is made to correspond with the outside
diameter of the blank to be forged, and the outside of the mould is or
may be strengthened by means of the steel or iron hoop d'; there are
holes through the hoop and partly through the mould for the ends of
the spikes e, by which the attendant turns the mould round during the
operation of forging.
The hammer face f which is let into the hammer c in the usual
manner can be made large enough to act on the whole surface of the
pile, but I prefer to make it narrow or with four arms, as shewn in Fig. 2,
so as to act by a succession of blows as the mould is turned slowly
round by the attendant.

page_text: '
When it is desired to make a hole in the blank a conical projection is
made on the anvil and on the hammer, which projections produce
corresponding recesses in the blank, as shewn in Fig. 4, and the film
of metal between the two recesses is afterwards removed by a punch as
usual.
The blank thus produced is then forged or rolled into a tyre, hoop, or
ring under a steam hammer, and in a rolling mill of the ordinary con-
struction. When the blank is forged the mould can easily be taken
off the anvil to remove the blank.
6
By means of these improvements the production is greatly increased 1
as the mould, which can be made of any diameter, according to the size
of blank required, is comparatively light and consequently casy of
manipulation.
Having thus stated the nature of my Invention, and described a con-
venient mode of performing the same, I wish it to be understood that 1
I do not intend to limit myself to the details given, and that I claim
the use of the movable mould d for forging the blanks of tyres, hoops,
and rings, and turning the same round when required during the opera-
tion of forging, as shewn and described.
In witness whereof, I, the said William Hassalwood Carmont, 2
have hereto set my hand and seal, this Nineteenth day of
November, One thousand eight hundred and seventy-five.
