AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF ROLLS TO BE USED IN SHAPING AND IMPRESSING SWEET- MEATS AND PLASTIC MATERIALS GENERALLY
Year: 1854

page_text: LETTERS PATENT to Richard Doidge, of Birmingham, in the County of
Warwick, Manufacturer, and John Cloves, of Birmingham aforesaid,
Machinist, for the Invention of "AN IMPROVEMENT OR IMPROVEMENTS IN
THE MANUFACTURE OF ROLLS TO BE USED IN SHAPING AND IMPRESSING SWEET-
MEATS AND PLASTIC MATERIALS GENERALLY."
Sealed the 15th September 1854, and dated the 24th March 1854.
PROVISIONAL SPECIFICATION left by the said Richard Doidge and
John Cloves at the Office of the Commissioners of Patents, with their
Petition, on the 24th March 1854.
We, RICHARD DOIDGE, of Birmingham, in the County of Warwick, Manu-
facturer, and JOHN CLOVES, of Birmingham aforesaid, Machinist, do hereby
declare the nature of the said Invention for "AN IMPROVEMENT OR IMPROVE-
MENTS IN THE MANUFACTURE OF ROLLS TO BE USED IN SHAPING AND IMPRESSING
SWEETMEATS AND PLASTIC MATERIALS GENERALLY" to be as follows:-
Our Invention consists in making the rolls used in the manufacture of
sweetmeats in the following manner, that is to say, we make the said rolls
of an easily fusible metal or alloy, instead of brass, as is commonly practised,
and we form the said rolls by casting the same upon an axis of iron, or steel,
or other metal. We cast the said rolls in moulds of brass or other metal,
and we make the said moulds in the following manner: we first make the
said mould of a cylindrical figure, and we attach to the interior of the said
mould, by rivetting or otherwise, models of the objects to be shaped or
impressed, the said models having been bent into a concave form, so as to fit

page_text: the hollow cylindrical surface of the mould. The said mould thus resembles
a hollow cylinder, with the objects to be shaped and impressed raised on its
surface. By casting in the said moulds we procure rolls, on the surface of
which the objects to be shaped and impressed are sunken. The essence of
our Invention consists in casting rolls in moulds, and making the said moulds
by attaching models of the objects to be shaped and impressed on the interior
hellom avlinder
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Doidge and John Cloves in the Great Seal Patent
Office on the 19th September 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD
DOIDGE, of Birmingham, in the County of Warwick, Manufacturer, and JOHN
CLOVES, of Birmingham aforesaid, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of March, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Richard Doidge and John Cloves, Her special licence that we, the said
Richard Doidge and John Cloves, our executors, administrators, and assigns,
or such others as we, the said Richard Doidge and John Cloves, our execu-
tors, 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 IMPROVEMENT OR IMPROVEMENTS IN THE MANUFAC-
TURE OF ROLLS TO BE USED IN SHAPING AND IMPRESSING SWEETMEATS AND PLASTIC
MATERIALS GENERALLY," upon the condition (amongst others) that we, the said
Richard Doidge and John Cloves, by an instrument in writing under our
hands and seals, or under the hand and seal of one of us, 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 I, the said Richard Doidge, on behalf of myself
and the said John Cloves, 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: We
Our said Invention consists of a method of making rolls used in the manu-
facture of sweetmeats by the method herein-after particularly described and
illustrated in the accompanying Drawing; rolls so manufactured being appli-
cable to the shaping and impressing of plastic materials generally. We make
the said rolls of an easily fusible metal or metallic alloy, instead of brass, as is
commonly practised, and we form the said rolls by casting the same upon an
axis of iron, steel, or other suitable metal. We cast the said rolls in moulds
of brass or other suitable metal or alloy, and we make the moulds in which
the said rolls are cast in the following manner: we first make the said
mould in the form of a hollow cylinder, as represented in Figure 1, which
said Figure represents in section one of the said hollow cylinders or moulds;
the said cylinder may be made in two or more parts; and the said parts may
be connected together by hinges, or in any other convenient manner.
then take models of the sweetmeats or other objects which we wish to shape
and impress by the rolls to be made, such, for example, as the models of
sweetmeats represented in Figure 2. We attach the said models, Figure 2,
to the interior of the hollow cylindrical mould, Figure 1, by rivetting, screw-
ing, or otherwise, the said models having been previously bent into a concave
form, so as to fit the hollow cylindrical surface of the mould. The said mould
thus resembles a hollow cylinder with the objects to be shaped and impressed
by the rolls standing in relief on its surface; one of the said moulds is repre-
sented in vertical section in Figure 3. The axle of the roller a, a, Figure 4,
is placed in the axis of the mould Figure 3, and the metal or alloy of which
the roll is to be made is poured into the said mould; we thereby obtain a roll
such as represented in Figure 4, that is to say, a roll on the surface of which
the objects to be shaped and impressed are sunken. If the objects to be
shaped and impressed require the same pattern or figure to be impressed on
both sides, a second roll similar to Figure 4 is used therewith. If the articles
to be made require a different pattern on opposite sides, two moulds and rolls
having dissimilar patterns must be used. If the objects are to be impressed
on one side only, the roll, Figure 4, may be used with a plain or cylindrical
roll. Although we have only described our Invention with reference to rolls
of a cylindrical figure of uniform diameter throughout, yet our Invention is
also applicable to rolls of varying diameter.
Having now described the nature of our said Invention, and the manner of
carrying the same into effect, we wish it to be understood that we do not limit
ourselves to the precise method herein described, as the same may be varied
without departing from the nature of our said Invention; but we claim as
our Invention, manufacturing rolls to be used in shaping and impressing

page_text: sweetmeats and plastic materials generally by casting the same in moulds,
and making the said moulds by attaching models of the objects to be shaped.
and impressed on the interior of a hollow cylinder or other shaped mould, as
herein described and illustrated in the accompanying Drawing.
In witness whereof, I, the said Richard Doidge, have hereunto set my
hand and seal, this Eighteenth day of September, in the year of our
Lord One thousand eight hundred and fifty-four.
Witness,
GEORGE SHAW.
