Improvements in and connected with Gas Cooking Stoves.
WILLIAM BIRCH 13 Holland Place Highfield Sheffield Caretaker do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to utilize the heat so as to prevent any obnoxious
fumes (or products of combustion) from entering the cooking chamber.
In my invention one or more chambers are formed in which atinospheric or other
gas burners are placed (hereinafter called (A)).
In close contact with (A) one or more cooking chambers are located
(called (B)).
The fumes or hot air is brought into contact with (B) by means of enclosed
chambers or flues (called (C)).
One or more cisterns for heating water (called (D)) may be placed in contact
with (A) the steam from which may be delivered into any one of (B).

I, WILLIAM BIRCH, of No. 13 Holland Place, Highfields, in the City of Sheffield,.
do hereby declare the nature of this invention and in what manner the same is to.
be performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to utilise the heat so as to prevent any obnoxious
fumes or products of combustion entering the cooking chamber.
According to my invention one or more chambers are formed in which atmospheric
or other gas burners are placed (hereinafter called, A). In close contact with, A,
one or more cooking chambers are located, called, B. The fumes or hot air is brought
into extended contact with, B, by means of enclosed chambers or flues called, C;
one or more cisterns for heating water called, D, may be placed in connection or
contact with, A, the steam from which may be delivered into any other chamber
or flue.
In order that my invention may be more clearly understood I will now describe
by way of example a cooking stove constructed according to my present invention by
reference to the accompanying drawings wherein
Fig. 1, represents a stove having its front and doors removed;
Fig. 2, is a side sectional elevation as on line, a, a, Fig. 1, to enable the general
arrangement of flues, C, being seen;
Fig. 3, is a top view with a portion removed to also show flues ;
Fig. 4, is a cross sectional view as on line, b, b, Fig. 1, to further show isolation of
oven, B, from the flues, C, circulating the products of combustion around said

page_text: oven, B, until finally they ascend to the top and escape by a suitable pipe or branch
into atmosphere.
The lower chamber, D, may be utilised to heat water or for any other desired
purpose, and other similar chambers or receptacles may be fixed or placed around the
sides or upon the top of the apparatus as will be readily understood, so that in no case
shall the fumes from the gas enter into any such chamber or receptacle.
To reduce the dispersion of heat by the flues the outer casing of the apparatus may
be formed of double plates leaving a closed space between said plates, said space
may contain air or any other bad conductor of beat; likewise the dimensions
number and arrangement of the several component parts may be varied and
modified to meet varying conditions and requirements while stiil retaining all the
elements of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In cooking stoves heated by gas the application of atmospheric or the like
burners in chainbers separated from the oven so that the products of combustion
of gas from said burners shall be conducted and circulated around such ovens by
means of flues or passages not having any internal connection with such oven or
other receptacle for edible substances, all substantially as herein described.
