IMPROVEMENTS IN COOKING APPARATUS
Year: 1859

page_text: LETTERS PATENT to Samuel Hazard Huntly, of Upper Baker Street, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN COOKING
APPARATUS."
PROVISIONAL SPECIFICATION left by the said Samuel Hazard Huntly
at the Office of the Commissioners of Patents, with his Petition, on
the 12th February 1859.
I, SAMUEL HAZARD HUNTLY, of Upper Baker Street, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN COOKING APPARATUS," to be as follows:-
This Invention is especially adapted for use in barracks, hospitals, prisons,
and similar places, but is also very suitable for schools and other large establish-
ments, being capable of boiling, steaming, baking, and roasting large quantities
of food with a small consumption of fuel.
The apparatus consists of an oven built of brick or stone, and heated by a
fire, the flame from which passes into the oven and out at a flue. The oven
is surrounded with brickwork or masonry, in which flues are formed and
provided with openings and sliding doors. A furnace is connected with theso
flues, and the flame passes through them to a chimney. A number of pots or
saucepans are fitted into the openings in the flues, and serve for boiling meat
or vegetables, and for preparing soup and other articles, and a corresponding
number of vessels with perforated bottoms for steaming vegetables, fish,
puddings, and other articles are made to fit over these boiling pots or
saucepans. The same furnace heats the oven, and the pots being provided
with suitable dampers or registers for adjustment to either purpose, or two

page_text: separate furnaces are used and so arranged that the fuel may be readily
removed from one to the other.. A boiler is placed over the oven door, or at
any convenient part of the flue, from which hot water can be drawn when
required, and which also supplies steam to a novel arrangement of dishes or
troughs with a plug in each, which is made to answer the purpose of a tap
for the admission of the steam. The above-mentioned steaming vessels are
made to fit over these troughs, and can then be used for steaming vegetables
or other articles of food for men, or for horses or cattle when required. By
this combined apparatus the processes of roasting, baking, boiling, and
steaming may be carried on simultaneously, or bread may be baked in large
quantities, and the heat which is applied for boiling also serves to maintain the
heat, or prevent loss of heat from the oven.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Hazard Huntly in the Great Seal Patent Office
on the 6th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
HAZARD HUNTLY, of Upper Baker Street, in the County of Middlesex, send

assigns, should at any time agree with, and no others, from time to time and
at all times thereaftor 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 COOKING APPARATUS," upon the condition (amongst others).
that I, the said Samuel Hazard Huntly, my executors, or administrators,
by an instrument in writing under my, or their, or one of their hands and
scals, 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.

page_text: NOW KNOW YE, that I, the said Samuel Hazard Huntly, 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, reference being had to the accompanying Drawing,
and to the figures and letters marked thereon, that is to say :-
This Invention is especially adapted for use in barracks, hospitals, prisons,
and similar places, but is also very suitable for schools and other large
establishments, being capable of boiling, steaming, baking, and roasting large
quantities of food with a small consumption of fuel.
The apparatus consists of an oven built of brick or stone, and heated by a
fire, the flame from which passes into the oven and out at a flue. The oven
is surrounded with brickwork or masonry, in which flues are formed and.
provided with openings and sliding doors. A furnace is connected with these
flues, and the flame passes through them to a chimney. A number of pots
or saucepans are fitted into the openings in the flues, and serve for boiling
meat or vegetables, and for preparing soup and other articles, and a
corresponding number of vessels with perforated bottoms for steaming
vegetables, fish, puddings, and other articles are made to fit over these boiling
pots or saucepans. The same furnace heats the oven and the pots, being.
provided with suitable dampers or registers for adjustment to either purpose;
or two separate furnaces are used and so arranged that the fuel may be readily
removed from one to the other. A boiler is placed over the oven door, or at
any convenient part of the flue from which hot water can be drawn when
required, and which also supplies steam to a novel arrangement of dishes or
troughs with a plug in each, which is made to answer the purpose of a tap for
the admission of the steam. The above-mentioned steaming vessels are made
to fit over these troughs, and can then be used for steaming vegetables or
other articles of food for men, or for horses or cattle when required. By this
combined apparatus the processes of roasting, baking, boiling, and steaming
may be carried on simultaneously, or bread may be baked in large quantities,
and the heat which is applied for boiling also serves to maintain the heat, or
prevent loss of heat from the oven.

Figure 1 of the accompanying Drawing is a front view or elevation of a
cooking apparatus constructed according to my Invention; Figure 2 is a plan
of the same; Figure 3 is a transverse section of the same through the boiler
and furnaces; Figure 4 is a transverse section through the oven; Figure 5
is a side view, and Figure 6 is a longitudinal section of the same; Figure 7
is a horizontal section through the flues; Figure 8 is a horizontal section
through the oven. The same letters refer to similar parts in each Figure.

page_text: A is the oven built of brickwork or stone, and arched over in the ordinary
manner; B is a furnace or fire-place, the flame from which passes into the
oven A and out at a flue C, and then through a short vertical flue C¹ into a
flue D leading to the chimney E. F is the door of the oven; a is the door of
the furnace B; b is the ash-pit, and c is the ash-pit door.
.
G is another furnace or fire-place, with its door d and ash-pit e. The flame
from this furnace divides into two portions, one of which passes through flues
H and I to the chimney E, while the other passes through a flue J under a
boiler K into the flue D, and thence to the chimney E. L is another flue
under the flue J, and like it, communicating with the flue D. The other end
of the flue L has a valve or register f over the oven door F for carrying off
the steam and vapour when the oven door is opened; g is a valve or damper,
which is moved by a handle g', and can be placed vertically as shown in
Figure 3, so as to shut off the flues J and L while the oven is being heated.
When the oven fire is extinguished, the damper or valve g can be shut down
horizontally on the flue C¹; h in Figure 8 is a door which may also be used
to close the flue C when the oven fire is not at work, and may be drawn
forward by a rod passing through a hole in the front of the apparatus when
the oven is being heated.
The flues D, E, I, are covered with iron plates, having a series of apertures,
each of which receives a saucepan or small boiler M, which may have a
steamer fitted on it. Each aperture has a sliding door N formed of a brick
or tile in an iron frame, which slides into a recess behind the aperture when
the saucepan or pot is in its place, but is drawn over the aperture when
the pot is removed. The Blues D and H run in a diagonal direction as shown
in Figure 7, so that the saucepan or pot nearest to the furnace has only a
small portion of its bottom exposed to the direct flame, while those farthest
from the furnace have the whole of their bottom surfaces exposed to the
flame. The intermediate pots have gradually more and more of their bottoms
exposed in proportion to their distance from the fire. By this means all the
pots can be made to boil in nearly equal times; the heat in the flues also
assists in maintaining the heat of the oven. When the oven is sufficiently
heated, the fire can be easily taken out of the furnace B with a shovel and
thrown into the furnace G.
The boiler K is furnished with a float and supply pipe and the usual
fittings of such low-pressure boilers, and furnishes steam for any required
purpose, or for the supply of a row of steamers O for steaming vegetables or
similar purposes. These steamers consist of shallow pans, troughs, or dishes,
ou which are placed the saucepans or vessels with perforated bottoms con-

page_text: taining the articles to be steamed. A branch from the steam pipe enters the
bottom of each dish, and is fitted with a hollow conical plug open at the
bottom, and having two opposite lateral perforations. This plug fits into a
conical hole which has two opposite notches extending about half way down
from the top of the hole; when the lateral perforations of the plug are placed
opposite to the notches the steam can pass through them, but when they are
turned away from the notches the passages are closed.
The part of the apparatus over the furnace G forms an ordinary hot plate,
and has openings and doors i, i, for heating saucepans or other articles, or at
which the operations of frying, broiling, and toasting may be performed.
Figure 9 is a perspective view of another cooking apparatus constructed
according to my Invention; Figure 10 is a horizontal section of the same, and
Figure 11 is a longitudinal section through the pots M. This apparatus is sup-
posed to be built against the wall of the building which encloses it. A is the oven,
which is built of brick or stone as before; B is the furnace, the flame from,
which heats the oven, and passes into a flue over the mouth of the oven in the
same position as the registerf in Figure 6. The mouth of the oven is closed
by a moveable iron door, or blower with a pipe or spout which fits into the
aforesaid flue, and directs the products of combustion into it. After the oven
the furnace to a long flue P, Q,
Above this flue is another flue D,
Each of these flues has a damper
is heated this blower is removed, and a plain iron door substituted for it; h is
a fire-brick door with an iron frame, which turns upon a hinge and shuts off
the furnace B when the oven is hot. K is a steam boiler placed over the
furnace B. J is a flue which leads from

which also communicates with the chimney.
at the chimney end. In the flue D are several large pots or boilers M, in
which are placed the vegetables or meat, or other articles to be boiled, or
which may be used for boiling water for making tea or other purposes; they
are provided with taps for drawing off the liquid; g is a valve or damper
which is moved by a handle g' on the outside.
When this damper is turned down it closes the flue P and opens the flue D,
and the flame or products of combustion then pass under the first pot M;
when this pot is hot enough or is out of use, the damper g is raised, and the
flue D is thus closed, and the flame is directed into the lower flue P. The
damper acts in a similar manner for directing the flame on or off the second
pot. By adjusting these dampers or registers in different intermediate
positions, the pots may be made to boil or become heated in equal times;
these dampers or registers may be applied to all the pots, or only to the first
ones, as may be found desirable. The steam from the boiler K may be used

page_text: for any required purpose, or it may be conducted by pipes and cocks into each
of the pots M. The contents of the pots may thus be repidly heated to the
boiling point, even before the flame is turned into the flues round them.
After the oven has been heated as herein-before described, the door / is
closed, and the chimney dampers of the flues J and D are opened, and the
flame is thus drawn through these flues, and directed under the pots M by the
registers or dampers g, j, and the contents of the pots are thus soon heated
with or without the assistance of the steam from the boiler K.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, I wish it to be understood that what I
claim is,―
First, constructing cooking apparatus with a brick or stone oven heated
from the interior in combination with a flue or flues containing or provided
with a series of pots or saucepans, or boilers or steamers, and so arranged that
the heat of the aforesaid. flue or flues contributes to maintain the heat or to
retard loss of heat from the oven, as herein-before described. I also claim
the farther combination of such combined apparatus as aforesaid with a steam
boiler, as herein-before described.
Second, constructing cooking apparatus with a brick or stone oven heated
from the interior in combination with a flue or flues, provided with a series of
pots, or saucepans, or boilers or steamers, and so arranged that the same
furnace heats both the oven and the pots, as herein-before described. I also
claim the farther combination of such combined apparatus as aforesaid with a
steam boiler, as herein-before described.
Third, the arrangement of steamers consisting of pots or saucepans with
perforated bottoms in combination with shallow dishes or troughs fitted with
conical plugs, as herein-before described in reference to Figures 1 and 2.
In witness whereof, I, the said Samuel Hazard Huntly, have hereunto
set my hand and seal, this Fifth day of August, in the year of our Lord
One thousand eight hundred and fifty-nine.
