Year: 1855

page_text: LETTERS PATENT to Stephan Goldner, of Wimpole Street, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS USED IN
COOKING Danan
MATTERS
"
PROVISIONAL SPECIFICATION left by the said Stephan Goldner at the
Office of the Commissioners of Patents, with his Petition, on the 9th
October 1855.
I, STEPHAN GOLDNER, of Wimpole Street, in the County of Middlesex, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS
USED IN COOKING AND PRESERVING ANIMAL AND VEGETABLE MATTERS " to be as
follows:-
This Invention has for its object improvements in the apparatus used when
cooking and preserving animal and vegetable matters.
For this purpose a hollow tray or vessel is formed of such depth as may
be required for receiving the metal cases which contain the matters to be
cooked and preserved. This tray or vessel is heated externally by steam in a
jacket or by other heated fluid. Over this tray or vessel is applied a moveable
cover, the edges of which enter a sand joint, or are otherwise formed, so as to
retain the heated atmosphere under this cover. The cases containing the
animal and vegetable matters are placed in the tray or vessel and heated
therein, thermometers being used to indicate the temperature; and there is.

page_text: an outlet to admit of the escape of the confined air from under the cover, and
also the vapours arising from the animal and vegetable substances, such
outlets being regulated by a cock or valve. By such apparatus heat be
applied more advantageously than heretofore to the cases containing animal
matters to be cooked or preserved.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Stephan Goldner in the Great Seal Patent Office on the
9th April 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHAN
GOLDNER, of Wimpole Street, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of October, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Stephan Goldner, Her special licence that I, the said Stephan Goldner,
my executors, administrators, and assigns, or such others as I, the said Stephan
Goldner, 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
USED IN COOKING AND PRESERVING ANIMAL AND VEGETABLE MATTERS," upon the
condition (amongst others) that I, the said Stephan Goldner, 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 immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Stephan Goldner, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in the apparatus used when
cooking and preserving animal and vegetable matters.

page_text: For this purpose a hollow tray or vessel is formed of such depth as may be
required for receiving the metal cases which contain the matters to be cooked
and preserved. This tray or vessel is heated externally by steam in a jacket
or by other heated fluid. Over this tray or vessel is applied a moveable cover,
the edges of which enter a sand joint, or are otherwise formed, so as to retain
the heated atmosphere under this cover. The cases containing the animal
and vegetable matters are placed in the tray or vessel and heated therein,
thermometers being used to indicate the temperature; and there is an outlet
to admit of the escape of the confined air from under the cover, and also the
vapours arising from the animal and vegetable substances, such outlets being
regulated by a cock or valve. By such apparatus heat may be applied more
advantageously than heretofore to the cases containing animal matters to be
cooked or preserved.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
According to the size of the cases in which the cooking and preserving of
animal and vegetable matters is to be performed, and the number of such
canisters which are to be heated at one time, I employ a tray with sides about
the height of the cases, and I prefer that the trays employed should only be
wide enough for receiving two rows of cases therein, so that each case or
canister, in addition to being heated at the bottom, may also be heated at the
side, so as to insure the heat continuing to the matters in the cases after the
cover of the tray has been removed, in order to allow of the opening in
each canister or case to be soldered or closed in opposition to steam.
The cover to each tray may be of any convenient form, with edges of
sufficient depth to admit of their descending some inches into a sand joint
around the sides of the tray. The tray is made suitable for being heated
externally at the bottom and sides by steam or other fluid. It is preferred
to have the heat of the atmosphere in the tray capable of being raised to
from 220° to 260° of Fahrenheit; and I believe the most convenient means
of heating such trays is by means of steam circulating in tubes, which are
coiled, and surround the tray on all sides, and also at the bottom. Or, in place
thereof, hot water circulating in tubes closed at all parts, and known as
Perkins mode of circulating and heating by hot water, may be used, in which
case the trays employed are surrounded at the sides and at the bottom with
such tubes. I would, however, remark that I make no claim to the means
which may be resorted to for heating the trays, nor do I confine myself to
any particular medium for so doing, my Invention consisting of covering in
the trays or vessels used during the time that heat is being applied to cases,

page_text: canisters, or metal vessels in which animal or vegetable substances are being
cooked, in order that such canisters may be surrounded on all sides and at top
by a highly heated atmosphere, no more vapour or steam being present than
that which rises from the canisters or cases in the tray. The object of the
Invention is, that highly heated atmospheric air should surround the cases or
canisters in which the animal and vegetable substances are placed to be cooked
and preserved.
The cover is formed with an outlet at its highest part, which is capable of
being regulated by a valve or cock, and the cover is arranged to be readily
raised or removed when it is desired to close or solder the openings in the
cases, canisters, or vessels.
In witness whereof, I, the said Stephan Goldner, have hereunto set my
hand and seal, this Eighth day of April, in the year of our Lord
One thousand eight hundred and fifty-six.
Witness,
WILL BRASIER.
STEPHAN GOLDNER. (L.s.)
