IMPROVEMENTS IN GAS STOVES FOR HEATING AND COOKING
Year: 1884

page_text: I RICHARD GEORGE of 31 Warrender Road Tufnell Park in the County of
Middlesex Civil Engineer do hereby declare the nature of my invention for
"IMPROVEMENTS IN GAS STOVES FOR HEATING AND COOKING" to be as follows:-
This Invention relates to improvements in gas stoves constructed and acting on
the principle described in the Specifications of Letters Patent granted to me dated
respectively the 11th October 1867 N° 2853 and 13th February 1868 N° 485 such
stoves being now well known as the "Calorigen." used for heating and ventilating
purposes.
Now according to my present improvements I construct gas stoves of this
character so as to adapt them for heating and cooking purposes the fumes of the
gas being completely separated from the food in the process of cooking the fumes
or products of combustion being entirely carried off from the apartment.
In carrying out my Invention atmospheric burners are fixed or arranged in the
oven or cooking chamber of the stove in such manner that the whole of the heat is
utilized for heating the interior before the food to be cooked is placed therein.
The heating of the oven is effected in a few minutes then a moveable bottom or
shelf is placed in the oven which divides the gas chamber and conducts the fumes
into a flue so arranged as to conduct them into a chimney or other outlet.
The interior of the oven is surrounded by an outer case which prevents loss of
heat by diffusion or otherwise.
By this means the cook the food and the apartment are protected from the
products resulting from the combustion of gas-a deadly vapour injurious to life
and health whether inhaled or taken into the system with the food after being
absorbed during the process of cooking.
The heat of my improved gas cooking stove or apparatus can be regulated to any
required degree by raising or lowering the gas the heat being completely utilized.
The ventilating power of the apparatus prevents the apartment from becoming
uncomfortably warm and the food is perfectly cooked throughout without injury to
its flavour or nutritive properties.
In using this improved cooking apparatus first remove the bottom plate or shelf
then light the gas burners. I would observe that it is not desirable to light an
atmospheric burner immediately the gas is turned on as a period of several seconds
should be allowed before lighting as the gas frequently ignites at the air inlet and
becomes a common instead of an atmospheric burner.

page_text: When the gas is properly ignited the door should be closed for from 10 to
20 minutes according to the heat required.
The bottom plate and slide or small plate should then be replaced to turn the
gas fumes into the outlet pipe and prevent them from coming in contact with the
food while cooking.
The grid or iron bars should be placed on the bottom plate to prevent the
cooking utensils from coming in contact with it.
The gas burners placed on the top of the oven are for the purpose of boiling
stewing frying or other cooking operations.

The grid or iron bars prevent too close contact of the cooking vessels employed
with the gas while the collars placed round the burners steady the flames so that
they may be brought down to the smallest possible degree.
The hood or top part of the oven is used to prevent the gas fumes and much of
the odour of cooking from entering. the apartment as they are carried off by a flue
from the back.

page_text: COMPLETE SPECIFICATION.
I RICHARD GEORGE of 31 Warrender Road,- Tufnell Park in the County of
Middlesex Civil Engineer, do hereby declare the nature of my invention for
"IMPROVEMENTS IN GAS STOVES FOR HEATING AND COOKING " and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement:-
This Invention relates to improvements in gas stoves constructed and acting on
the principle described in the Specifications of Letters Patent granted to me dated
respectively the 11th October 1867 N° 2853 and 13th February 1868 N° 485 such
stoves being now well known as the "Calorigen" used for heating and ventilating
purposes.
Now according to my present improvements I construct gas, stoves of this
character so as to adapt them for heating and cooking purposes, the fumes of the
gas being completely separated from the food in the process of cooking the fumes or
products of combustion being entirely carried off from the apartment.
And in order that my Invention may be clearly understood and readily carried
into practice I will proceed to describe the Drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
The nature of each of the views being written upon the Drawings it will not be
necessary to repeat the same here.
In carrying out my Invention atmospheric burners a are fixed or arranged in the
oven or cooking chamber b of the stove A in such manner that the whole of the
heat is utilized for heating the interior before the food to be cooked is placed
therein.
The heating of the oven is effected in a few minutes then a moveable bottom
plate or shelf c is placed in the oven which plate c divides the gas chamber d from
the oven b and conducts the fumes into a flue e so arranged as to conduct them
into a chimney or other outlet f.
The interior of the oven is surrounded by an outer case g which prevents loss of
heat by diffusion or otherwise.
By this means, the cook, the food, and the apartment are protected from the
products resulting from the combustion of gas-a deadly vapour injurious to life
and health whether inhaled or taken into the system with the food after being
absorbed during the process of cooking.
The heat of my improved gas cooking stove or apparatus can be regulated to
any required degree by raising or lowering the gas by means of taps h. h. the heat
being thus completely utilized.
The ventilating power of the apparatus prevents the apartment from becoming
uncomfortably warm and the food is perfectly cooked throughout without injury to
its flavor or nutritive properties.
In using this improved cooking apparatus first remove the bottom plate or
shelf o then light the gas burners. I would observe that it is not desirable to light
an atmospheric burner immediately the gas is turned on as a period of several

page_text: seconds should be allowed before lighting as the gas frequently ignites at the air
inlet and becomes a common instead of an atmospheric burner.
When the gas is properly ignited the door should be closed for from 10 to
20 minutes according to the heat required.
•
The bottom plate c and slide or small. plate c¹ should then be replaced to turn
the gas fumes into the outlet pipe f and prevent them from coming in contact with
the food while cooling.
ཙ ཙ ''ཨིཏྟཱ བ་
The grid, or iron bars i should be placed on the bottom plate c when the slide c¹
is closed to prevent the cooking utensils from coming in contact with it.
The gas burners a' placed on the top of the oven are for the purpose of boiling
stewing frying or other cooking operations.
A grid or frame of iron bars such as i may be placed over the burners a¹ to
prevent too close contact of the cooking vessels employed with the gas while the
collars placed round the burners a steady the flames so that they may be brought
down to the smallest possible degree.
The hood or top part k of the oven is used to prevent the gas fumes and much of
the odour of cooking from entering the apartment as they are carried off by a pipe
or flue from the back.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that I make
no claim to any of the parts separately which are well known and in common use
but what I claim is.".

First. The improved arrangement and construction of gas stoves for heating and
cooking in which the gas combustion chamber is isolated from the cooking chamber
or oven during the process of cooking, substantially in the manner and for the
purpose herein before described and represented in the drawings annexed.
Second. I claim the improved general arrangement and construction of gas
stoves for heating and cooking substantially as herein described and represented in
the drawings annexed.
