page_text: LETTERS PATENT to John Joseph Parkes, of 17, London Street;
Paddington, in the County of Middlesex, Gas Engineer, for the
Invention of "IMPROVEMENTS IN GAS STOVES OR APPARATUS FOR COOKING
AND HEATING PURPOSES."
Sealed the 30th May 1871, and dated the 2nd December 1870.

PROVISIONAL SPECIFICATION left by the said John Joseph Parkes
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd December 1870.
I, JOHN JOSEPH PARKES, of 17, London Street, Paddington, in the
County of Middlesex, Gas Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN GAS STOVES OR APPARATUS FOR COOKING
AND HEATING PURPOSES," to be as follows:-
These improvements refer to the construction of a stove of the following:
character:-This stove is adapted not only for warming a room or
apartment, but also for certain operations of cookery such as baking,.
stewing, and boiling. It consists of an iron or other suitable case as in
the ordinary gas stoves, but in this stove, in the lower part thereof, gas

page_text: burners are placed which are covered with a cage of wire gauze or other
suitable open work, and higher up in the stove an oven is provided
which partly projects from the front of the stove but has heat spaces
which are open at the bottom part of the oven to admit the heat from
the burning gas such heat spaces surrounding the internal case of the
oven except in the front where the door thereof is situate, so that although
the oven is heated by the heat from the burning gas from the burners
the viands to be baked are shut off from contact with the gases or
vapours proceeding from the burning gas in the non-projecting part of
the stove. Above the oven is a space into which a boiler, stew pan,
or vessel can be fitted, a top cap or cover being provided in order that
such boiler or stew pan may be shut in or open at top as may be desired,
and the upper part of the stove is so arranged that the heat has to pass
around the boiler or stew pan, and the waste heat then passes up a
chimney provided for the same. As the oven projects beyond the front
of stove there is in the interior of the stove a space at the back of the
oven opening direct to the upper part thereof, where the boiler or stew
pan can be placed so that the heat can ascend_to the boiler or stew pan
and heat the same, but when it is desired to concentrate heat upon the
oven this space can be wholly or partially closed. If thought desirable
other gas stove appliances might be used with my stove, and a twisted
pipe for heating liquid may also be used.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Joseph Parkes in the Great Seal Patent
Office on the 2nd June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JOSEPH PARKES, of 17, London Street, Paddington, in the County of
Middlesex, Gas Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of December, in the year:
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Joseph Parkes, Her special
licence that I, the, said John Joseph Parkes, my executors, adminis-
trators, and assigns, or such others as I, the said John Joseph Parkes,

page_text: .
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 GAS STOVES OR APPARATUS FOR COOKING AND HEATING
PURPOSES," upon the condition (amongst others) that I, the said John
Joseph Parkes, 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 John Joseph Parkes, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
These improvements comprehend the construction of gas stoves in the
following way, that is, I construct any such stove so that it is adapted
not only for warming a room or apartment, but also for effecting certain
cookery operations such as baking, stewing, and boiling, similarly to
ordinary gas stoves, it consists of a proper exterior case of iron or other
suitable material but in my stove in the lower part thereof, gas burners
are placed which are covered with a cage of wire gauze or other suitable
open work, and higher up in the stove an oven is provided which pro-
jects from the stove and has heat spaces which are open at the bottom
part of the oven to admit the heat from the burning gas such heat spaces
being situate between the outer and an inner case which forms the oven
proper, so that although the oven is heated by the heat from the burning
gas from the burners the viands to be baked are shut off from contact
with the gases or vapours proceeding from the burning gas in the non-
projecting part of the stove. Above the oven is a chamber or space
into which a boiler, stew pan, or vessel can be fitted, a top, cap, or cover
being provided in order that such boiler or stew pan may be shut in or
open at top as may be desired, and the upper part of the stove is so
arranged that the heat has to pass around the boiler or stow pan, and
the waste heat then passes up a chimney. As the oven projects beyond

page_text: the front of the stove there is in the interior of the stove a space at the
back of the oven opening direct to the upper part of the stove where
the boiler or stew pan can be placed as above mentioned, so that the
heat can ascend to the boiler or stew pan and heat the same, but when
it is desired to concentrate heat upon the oven this space can be wholly i
or partially closed. If thought desirable other gas stove appliances
might be used with my stove and a twisted pipe for heating liquid can
be used. And the form of the stove might be such that the oven should
not project but be flush with the outer surface, and charcoal or other
heat producing medium may be substituted for the herein described 1
heat supply arrangements if deemed desirable.
Having thus particularly described the nature of the said Invention
and incidentally adverted to the manner of performing or putting in
practice thereof, I in compliance with the aforesaid condition in the
said Letters Patent contained now proceed to particularly describe and 1
ascertain in what manner the said Invention is to be performed, or
carried out in practice by reference to the accompanying Drawings, as
Follows

page_text: .
to circulate around the oven-proper, as shown-by-the said arrows:
F, opening to boiler chamber from top of oven; G, opening closed by the
damper, as shown in Fig. 2, and leading to passage at back of oven which
communicates with the boiler chamber above. This boiler chamber is
made with two rings (No. 1) marked x in the Drawing, and (No. 2)
marked xx. The effect being that when the boiler pot is inserted
as shown on the Drawings the passage for the heat is of a screw like
character; H is an opening in the flanged top of the oven proper to
admit of the heated gas passing over the top of the oven proper to the
opening F before mentioned, K shows the ledge formed on the inside
of outer case of oven on which oven proper rests affording heat space at
bottom of oven.
.
Having now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same may be
performed.or carried out in practice, I hereby declare that I claim, the
herein described. Invention of "Improvements in Gas Stoves or Appa-
ratus for Cooking and Heating Purposes," a novel and important feature
of which is that in a stove suitably arranged for warming an oven is
provided, which is heated by heat spaces so disposed that the heated
vapour does not come in contact with the viands."
In witness whereof, I, the said John Joseph Parkes, have hereunto
set my hand and seal, this First day of June, in the year of
our Lord One thousand eight hundred and seventy-one.
