Improvements in and connected with Gas Cooking and Heating
Stoves.
We, ERNEST WILLIAM BEECH, of 11, The Pavement, Wanstead, E., & ALFRED
GEORGE MELIUISHI, of 20, Hinckley Road, East Dulwich, Engineers, do hereby
declare the nature of this invention to be as follows:-
In gas cooking stoves as hitherto made and constructed no provision has been
made for general heating purposes, such as is required, and necessary when such
stoves are used in a kitchen or other living room.
Now the object of our invention is to provide an effective external heating
arrangement in combination with a gas cooking stove which whilst being effectual
as a heating arrangement is also cheerful looking.
For instance we propose to provide an asbestos core fire in the cooking oven
door, the gas supply arrangement being such that the door can be opened without
affecting the fire. When the door is shut a cheerful exterior fire can be maintained
which will take the place of an ordinary kitchener.
The heating arrangement need not always be in the door but formed on each
side of the oven door either in the form of an asbestos fire, or Bunsen or Argand
burner, such as is used in what are known as "hygienic" stoves, the chief object
being the combination of a gas cooking stove and external heating appliance.
A further improvement consists in providing means for heating water for a
circulatory system or as an ordinary boiler & for this purpose a suitably shaped
boiler is fitted preferably at the top and inside the oven said boiler being so
arranged that the heat products, are compelled to pass through a circuitous route
to the atmosphere, so that a comparatively large surface is provided for retaining
said heat & conveying it to the water.
Or preferably a separate set of burners may be fitted to heat the boilers
directly without regard to the oven.
The external heating fire or burner is so arranged that the products are caused
in passing to heat the boiler. The door is so hung that it can be opened either
to the right or left, so that a stove constructed upon our principle can be used
in almost any position.

page_text: declare the nature of this invention and in what manner the same is to be per
formed, to be particularly described and ascertained in and by the following
statement:
In gas cooking stoves as hitherto made and constructed, no provision has been
made for general heating purposes, such as is required, and necessary when such
stoves are used in a kitchen or living room.
Now the object of our invention is to provide an effective heating arrange-
ment, in combination with a gas cooking stove, which whilst being effectual as
a heating arrangement is also cheerful looking.
For instance we propose to provide an asbestos fire in the cooking oven door,
the gas supply arrangement being such that the door can be opened without
affecting the fire. When the door is shut a cheerful looking stove is obtained
which will take the place of an ordinary kitchener.
وو
The heating arrangement need not always be in the door but formed on each
side of the oven door either in the form of an asbestos fire or burner, or
Argand burner, such as is used in what are known as "hygienic stoves the
chief object being the combination of a gas cooking stove & exterior heating
appliance.
A further improvement consists in providing means for heating water for a
circulatory system, or as an ordinary boiler, & for this purpose a suitably shaped
boiler is fitted preferably at the top and inside, the oven said boiler being so
arranged that the heat products are compelled to pass through a circuitous route
to the atmosphere, so that a comparatively large surface is provided for retaining
said heat and conveying it to the water.
Or preferably a separate set of burners may be fitted to heat the boilers directly
without regard to the oven.
The external heating fire or burner is so arranged that the products of com-
bustion are caused in passing to heat the boilers. The door is so hung that it
can be opened either to the right or left at will. In order that our invention
may be perfectly understood we have appended the accompanying sheet of draw-
ings in which Figure 1 is a front elevation of a gas cooking stove as constructed
according to our invention, Fig. 2, being a sectional elevation shewing more clearly
the circulating cistern or boiler & the arrangement of the coil over the burners,
and also the particular arrangement and passage of the flue ways from the
warming stove in the oven door. Fig. 3, is a front elevation of a gas cooking
stove in which the warming stove or stoves form part of the cooking stove itself,
& not in the door. Fig. 4, is a sectional plan on the line A. B, Figure 1, and it is
also equivalent to a section on the line C, D, Figure 1. Figs. 5 & 6, are sectional
views of the oven burners shewing their approximate position in relation to the
circulating geyser or boiler pipes. Figs. 78 & 9 are detail views explanatory of
the right and left hand opening hinge.
Before proceeding to describe in detail the peculiar features so far as the con-
struction is concerned, we propose here to enumerate the advantages sought, and
afterwards point out how they are obtained.
In the first place an ordinary gas cooking stove is usually put out in the
scullery of small houses, for the reason that it is of no practical use for warming
purposes.
Secondly. When so placed, an expenditure for coal is necessary in the kitchen
for general warming purposes, and also for heating the circulatory system to
the bath if such be fixed in the house.
Thirdly. The gas cooking stove is ordinarily used as a matter of domestic
economy, especially in the summer, whereas in the winter it is in reality an added
expense by reason of the proposition set out in the second head.
Now by our invention we propose to combine the functions of cooking, warming
the room, and heating the circulatory system in one apparatus, and so construct

page_text: the same that it will be a desirable substitute for the ordinary kitchen range,
thus doing away with the necessity of using coal as a warming medium.
The stove will warm the room and at the same time be cheerful looking.
The products of combustion or hot gases as they escape from the warming
stove in the oven door or at the side of the oven will be utilized to heat the
water in the cistern or circulatory pipes.
The warming stove can be used independently from the cooking stove.
The burners in the cooking stove will heat the water in the circulatory system
or cistern at the same time as cooking is carried on without any appreciable loss
of heat, or detriment to the cooking power of the oven. Or the burners may be
so used as to cook only, without heating the water.
Or the heat of the burners may be so confined as to heat the water only & not
cook in which latter case it is estimated that more water can be heated with a
given quantity of gas than has been accomplished before.
In the case of a gas cooking stoves with the warming appliances at the sides
thereof the door is so arranged that it can be swung open on either side at will
by simply turning the handle on that side of the door it is wished to open.
The warming stoves in this case also can be utilized to heat the circulatory
system by means of a coil.
Hot water can be drawn at the stove. Cold water also can be so drawn so
that a stove constructed on the above lines, provides every necessity for cooking
& heating purposes.
In Figs. 1 & 2 A¹ is the gas fire, here shewn as asbestos, but may of course be
of any known type, the gas being supplied by pipe B, & swing joint C¹ formed in
the hinge of oven door, or coincident therewith at a higher or lower level. Pro-
ducts of combustion pass away by flue E, into chamber F, above the oven,
thence by pipe G communicating with said chamber F to any desired place.
The cistern H may be either of the open or high pressure type & is preferably
attached to the back of the stove, with a circulating pipe I in the chamber F,
which picks up the waste heat from the fire A & by circulation heats the water in
the cistern H.
The oven door with the gas fire can be swung open without in any way effecting
the gas supply, or the swing joint may be so formed as to lower the gas of the
gas fire when door is open.
The oven burners J, J are rotatable, by means of the levers K, K, connecting
rods L, L, and handle M, without affecting the gas supply and almost immediately
above them is arranged the circulatory or geyser pipe or coil N, the rising end P
of which is carried nearly to the top of the cistern H for discharge of heated
water, the return Q being connected to the bottom of the cistern.
The cold water supply R is connected by a syphon S to the cistern H and a
draw off tap T is brought to a convenient position at the side of the oven &
towards the front by a pipe U the hot water tap V being similarly situated but
connected to the top of the cistern or boiler H.
The flame from the burners J, J, is caused to impinge upon the coil N, thereby
causing the water to circulate & become highly heated in the cistern or boiler H.
At the same time the oven is heated for cooking purposes, the amount of heat
extracted for heating the water being inappreciable: if however the whole of
the heat is required for cooking, this can be obtained by turning the handle M
which by the connecting rods L L will turn the burners to bring the flame above
the coil, as indicated in Figure 6, thus allowing the whole of the heat to be
utilized for cooking.
On the other hand, if it is desired to use the whole of the heat for heating
the coil, a baffle or muffle W is used, which effectually confines & radiates the heat
upon all sides of the coil pipe which now rapidly heats the water for a compara-
tively small expenditure of gas.
The water so heated may be delivered by the pipe X on the single pipe system
to any part of the house by the displacement of the entering cold water at the

page_text: bottom of the cistern H which is in turn rapidly heated by circulation through
the coil or geyser. It is proposed to employ a single coil or pipe above the burners
& this of small diameter, so that when a quantity of hot water is drawn off the
entering cold water will no appreciably affect the temperature of the oven, by
reason of the small amount of cooling surface exposed. For the same reason the
cistern H is attached to the stove & not formed in it although it may be pro-
tected from loss of heat by radiation by covering same with some non conductor.
Referring to Fig. 4 we have no deemed it necessary to shew a cistern attached,
as we wish it to be quite clear that we do not confine ourselves to the particular
combination shewn as some stoves may be fitted with the warming stoves & not
with the circulatory system & vice versa. The side columns Y Y are those known
as "hygienic" stoves & may be used for warming & heating water also upon the
same system as explained with reference to Figs. 1 & 2, or they may simply heat
water in an open cistern surrounding the flue as can be easily understood.
In a stove of this description or in an ordinary gas cooking stove we prefer to
so hang the door that it can be opened on either side at will, for instance the
door is provided at the top with a rocking lever a pivoted at 6 to the door frame
the ends c, c, projecting beyond the edge of the door on either side being formed
with an eye c for engagement over the hinge pins d, d attached to or forming part
of the stove. Near the ends of the rocking lever but preferably inside the oven
door; or between the casing thereof are two connecting rods e, e, engaging by
means of a slot with the bell crank handles f f of the door.
The lower end of the door is supported by the pins g, g resting in a socket h
cast or attached to the oven frame.
If it is desired to open the door from left to right, the left hand bell crank or
door handle is moved towards the left with the result that by means of the con-
necting linke the eye c of the rocking lever is moved clear of the hinge pin, d
but on the opposite side, the eve c is moved further down upon its hinge pin and
as this pin is taper it draws the top of the oven door over to that side just suffi-
ciently to release the bottom pin g out of its shallow socket h and allow the door
to open.
The bell crank or door handle on the left hand side cannot be moved to the right
to lift the eve off its pin because the lower end of the connecting link e is slotted
so that it follows no movement can be imparted to the rocking lever on either side
except by an upward thrust. Moreover when the door is ever so slightly open
the eye acting as the hinge cannot be lifted until the door is closed because it is
arranged that the angular projection engages under a lug or in a recess of
the oven framing to prevent same from lifting above the pin. Or instead of the
rocking lever an arrangement shewn in Figs. 7 & 8 may be used in which case the
door is provided with hinge pins at each corner, the two top pins j, i, engaging
within recesses, through which a holt k is arranged to slide in such a manner
that either one or other of the pins is locked in position to act as a hinge, accord-
ing to whichever side the door is required to open, the sliding bolt k being
preferably operated by a pinion attached to a handle at the top of the oven door
engaging a rack m cut on the side of said sliding bolt. The bolt is of such
length that one hinge pin is always fully covered & secure before the other is
set free.
Having now particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed we declare that what we
claim is:-
(1) The use of a gas heating appliance in combination with the door of a gas
cooking stove. & so arranging the gas supply thereto that an uninteruppted
supply of gas is obtained with the door either opened or closed as described.
