Improvements in Gas Cooking Apparatus, Ovens and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a gas cooking stove as hereinafter described.
This novel gas cooker, which I term L'Europeene,"
essentially in its construction by the following points:
is characterised
1. By the arrangement of its oven which is provided on its periphery with a
series of apertures in order to permit of the horizontal admission of the hot gases
and of effecting the cooking of the objects placed in the oven.
This cooker may be employed for cooking roast meats, gratins, pastry, bread
and for grilling. In order to effect this latter operation, that is to say grilling,
the oven is provided at its upper portion with a row of ordinary white-burning
gas jets, supplied through a gas tap. Two slides are likewise fixed within the
oven for supporting the pan and the grill for receiving the food to be grilled.
Owing to the arrangement of this horizontal row of white-burning jets, grilling
may be effected without the help of the lower burners.
Pastry being more rapid and more susceptible in its cooking, is liable to
become burnt underneath; in order to obviate this defect, which is caused by
the proximity of the burner, I employ an insulating disc formed of two plates
(preferably of sheet metal) between which is inserted some suitable insulating
substance, such as mineral cotton, for example. This disc is mounted upon feet
in order to enable it to be placed upon the bottom of the oven, and at the same
time enabling the heat to circulate freely between the disc and the bottom of
the oven.
For all other uses, such as roasting and so forth the disc above referred to
is replaced by a bar grating which is also mounted upon feet so that it may
rest upon the bottom of the oven.
The feet of the disc and grating are of such a height that the disc or grating
are at the same level as the door when open, thus facilitating the charging of
the oven and the removal of the objects from the same.
A movable plate provided upon the whole of its periphery, with a number
of holes allows the heat to circulate freely, and permits of effecting simul-
taneously in the oven, roasting at the lower portion, and of cooking a gratin,
bread, pastry and so forth above the plate. In the case of a large oven, I use
a plate having apertures for the passage of the heat arranged vertically and
alternately upon the periphery and in the middle of the plate in order that they
may direct the current of hot gases horizontally whilst at the same time pre-
venting the liberating holes from being blocked.

page_text: In order to prevent the flames from reaching the bottom of the oven, this latter
is separated from the burner by an ordinary cast metal disc.
Finally it should be pointed out that the gas is conducted to the burner by
the manipulation of the cock which is provided with a dial and with a pilot
light, and acts with mixture of air the air necessary to support combustion
enters in the front of the oven which is perforated for this purpose, but it may
also be caused to pass beneath the bottom, if so desired.
2. By a double circulation of the heated gases with the object of utilising
them to the maximum extent and in order to avoid any cooling of the oven.
This utilisation and maintenance of a maximum temperature in the oven, are
secured by the arrangement of an envelope forcing the gases, when they have
escaped by the aperture at the top of the oven, to pass externally over the whole
of the top of this latter and to re-descend around the oven, then to again rise
and finally escape at the upper part of the apparatus, either directly into the
room through the upper apertures provided at the back of the apparatus, or by
means of a flue into a chimney, if so desired.
This cooking stove is completed by the arrangement at its upper portion of
a series of burners.
The decoration and dimensions of the various portions of this cooking stove
may be of any desired kind, its novel internal arrangements alone forming the
subject of my invention.
From the description of the construction which has been given, it will readily
be understood that with an exceedingly small expenditure, there is obtained
in this oven a maximum of temperature and a perfect and rapid cooking action.
In the above description it has been assumed that the improvements are applied
to a gas cooker having an oven of rectangular form, but it will of course be
understood that the said improvements may be applied to cookers or kitcheners,
to ovens for confectioners, bakers or painters, for baking varnish upon tin plate
goods, cycle parts and so forth, in short for all purposes where it is desired to
obtain a maximum of temperature with a minimum of expense.

Improvements in Gas Cooking Apparatus, Ovens and the like,
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
-
This invention relates to a gas cooking stove as hereinafter described and
illustrated in the accompanying drawings in which
Figures 1 and 2 shew respectively in longitudinal and horizontal section the
construction of an apparatus of ordinary size.
Figures 3, 4 and 5 are detail views of parts of this oven, and
Figures 6 and 7 represent respectively in longitudinal and cross-section the
preferred form of construction for a large apparatus intended either for a very
large kitchen or for use for industrial purposes.
This novel gas cooker, which I term " L'Européenne", is characterised
essentially in its construction by the following points:

page_text: 1. By the arrangement of its oven F (see Figures 1, 2, 6 and 7) which is
provided on its periphery with a series of apertures R R in order to permit of
the horizontal admission of the hot gases and of effecting the cooking of the
objects placed in the oven.
This cooker may be employed for cooking roast meats, gratins, pastry, bread
and for grilling. In order to effect this latter operation, that is to say grilling,
the oven is provided at its upper portion (see Figures 1 and 2) with a row of
ordinary white-burning gas jets A, supplied through a gas tap C. Two slides
are likewise fixed within the oven for supporting the pan and the grill for
receiving the food to be grilled. Owing to the arrangement of this horizontal
row of white-burning jets, grilling may be effected without the help of the
lower burners B.
Pastry being more rapid and more susceptible in its cooking, is liable to
become burnt underneath; in order to obviate this defect, which is caused by the
proximity of the burner, I employ an insulating disc D. (see Figures 1, 2 and 3)
formed of two plates (preferably of sheet metal) between which is inserted some.
suitable insulating substance, such as mineral cotton, for example. This disc
is mounted upon feet in order to enable it to be placed upon the bottom of the
oven, and at the same time enabling the heat to circulate freely between the
disc and the bottom of the oven.
For all other uses, such as roasting and so forth the disc 1) above referred
to is replaced by a bar grating E (see Figure 4) which is also mounted upon feet
so that it may rest upon the bottom of the oven.
The feet of the disc and grating are of such a height that the disc or grating
are at the same level as the door when open, thus facilitating the charging of
the oven and the removal of the objects from the same.
A movable plate T provided upon the whole of its periphery with a number
of holes r (see Figures 1 and 5) allows the head to circulate freely, and permits
of effecting simultaneously in the oven, roasting at the lower portion, and of
cooking a gratin, bread, pastry and so forth above the plate. In the case of
a large oven, I use the form of plate shewn in Figures 6 and 7, that is to say a
plate having apertures for the passage of the heat arranged vertically and
alternately upon the periphery and in the middle of the plate in order that they.
may direct the current of hot gases horizontally whilst at the same time preventing
the liberating holes from being blocked.
In order to prevent the flames from reaching the bottom of the oven, this
latter is separated from the burner by an ordinary cast metal disc S.
Finally it should be pointed out that the gas is conducted to the burner B
by the manipulation of the cock H which is provided with a dial H and with
a pilot light, and acts with mixture of air at the point K; the air necessary to
support combustion enters at L in the front of the oven which is perforated for
this purpose, but it may also be caused to pass beneath the bottom, if so desired.
2. By a double circulation of the heated gases with the object of utilising
them to the maximum extent and in order to avoid any cooling of the oven.
This utilisation and maintenance of a maximum temperature in the oven, are
secured by the arrangement of an envelope or casing G forcing the gases, when
they have escaped by the aperture at the top of the oven, to pass exernally over
the whole of the top of this latter and to re-descend around the oven, then to
again rise and finally escape at the upper part of the apparatus, following the
path indicated in Figures 1, 2, 6 and by the arrows, either directly into the
room through the upper apertures J provided at the back of the apparatus, or
by means of a flue into a chimney, if so desired.
This cooking stove is completed by the arrangement at its upper portion of
a series of burners.
The decoration and dimensions of the various portions of this cooking stove
may be of any desired kind, its novel internal arrangements alone forming the
subject of my invention.

page_text: From the description of the construction which has been given, it will readily
be understood that with an exceedingly small expenditure, there is obtained in
this oven a maximum of temperature and a perfect and rapid cooking action.
In the above described and accompanying drawings it has been assumed that.
the improvements are applied to a gas cooker having an oven of rectangular
form, but it will of course be understood that the said improvements may be
applied to cookers or kitcheners, to ovens for confectioners, bakers or painters,
for baking varnish upon tin plate goods, cycle parts and so forth, in short for
all purposes where it is desired to obtain a maximum of temperature with a
minimum of expense.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:-
1. In a gas cooker or oven, the arrangement described and represented enabling
the heat to be directed horizontally through the perforated walls of the oven in
order to effect a more rapid cooking of the objects placed therein.
2. In a gas cooker or oven as described in Claim 1, the arrangement of plates
perforated vertically either upon their extremities or in their middle portion,
as indicated in Figures 6 and 7, for the purpose of obtaining a better diffusion
of the heat and facilitating the issue of the gases by preventing any stoppage
of the discharge apertures.
3. The combination with a gas cooker or oven as described in Claim 1, of a
horizontal row of gas jets burning with a white flame, which being mounted
at the upper portion of the oven enables grilling to be carried on without the
assistance of the lower burners.
4. The arrangement in a gas cooker or oven of a double wall surrounding the
oven for the purpose of compelling the hot gases, after they have escaped through
the aperture at the upper portion of the oven, to again descend over its entire
surface and re-ascend externally, in order to then either become distributed
directly into the room or be conducted into a chimney, the whole substantially
as above described and represented in the accompanying drawings.
5. The application to gas cookers or ovens of the isolating disc D above
described.
