I, EDWIN BOWEN of Birchfield Road, Perry Barr near Birmingham in the County
of Warwick, Tin plate-Worker, do hereby declare the nature of this invention to be
as follows:
My invention consists of the improvement, or improvements hereinafter described,
in lamp and gas cooking stoves, whereby the superficial heating surfaces of the said
stoves, are greatly increased, and their arrangement improved; by which means, the
maximum amount of heat is obtained, with a minimum expenditure of oil or gas.
I will describe my invention, in connection with a lamp cooking stove.
The stove consists of a series of rectangular shaped plates, connected together, so as
to form an enclosure, with horizontal divisional spaces, which constitute heating
chambers, which are situated between vertical flues or passages, leading respectively
from the burner chamber, situated at the base of the stove, and from the horizontal
heating chamber, which leads to a crown space, at the summit of the stove.
In ordinary lamp stoves, the lamp is elevated above the base, and the heat and
products of combustion, given off from the flame of the said lamp, is made to pass up
side heating flues or spaces, and is from thence, conducted to an exit flue.
According to my invention, I form an upright rectangular shaped chamber, made
up of a series of metallic plates, connected together at their meeting edges, so as to
form an enclosure, which is divided off into compartments, viz., a lower compartiment,
which is the lamp chamber, and a middle compartment, which is a heating chamber;
and which said heating chamber, extends to the whole superficial area of the cross
section of the stove; and situated within the crown of the stove, is another compart-
ment, wherein the heat, after circulating through the system as hereinafter described,
is conducted, and from thence passes away, through back openings, or piercings into
the atmosphere.
'
Connected. with the lower, middle, and upper horizontal chambers, are vertical
passages, respectively leading from the lamp chamber, into the middle heating
chamber, and two vertical passages, directed from the said heating chamber, into the
crown chamber, and which said last named passages, are arranged at suitable distances
apart, and at short distances from the sides.

page_text: The top of the stove is provided with holes or openings, with lids, through which,
culinary vessels are placed, for heating or. boiling purposes, and which said holes
preferably come opposite the upward passages; so that on a vessel being placed in
one of the said passages, its partial choking, in no way interferes with the proper
circulation of the heat."
The lower vertical passage, whereunder a lamp is placed, is situated at a short
distance from one of the sides, and may come opposite one of the said upper vertical
passages.
The intervening spaces between the horizontal heating chambers, or shallow spaces,
and vertical passages or flues, are ovens, or baking or heating compartments.
Thus, the heat and products of combustion, given off from the lamp, passes
vertically upwards, through the divisional flue, into the middle and shallow heating
chamber, and from thence, circulates up one or both of the vertical flues, into the
crown chamber, or direct through holes or piercings, in the back of the stove.
The regenerative principles upon which the stove is constructed, destroys or renders
harmless, the products of combustion given off therefrom.

page_text: 1, EDWIN BOWEN of Birchfield Road, Perry Barr, near Birmingham in the County
of Warwick, Tin-plate worker 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 :-
1-
My invention consists of the improvement, or improvements, herein after described,
in lamp, and gas cooking stoves, whereby the superficial heating surfaces of the said
stoves, are greatly increased, and their arrangement improved; by which means, the
maximum amount of heat is obtained, with a minimum expenditure of oil or gas.
I will describe my invention, in connection with a lamp cooking stove.
The stove consists of a series of rectangular shaped plates, connected together, so as
to form an enclosure, with horizontal divisional spaces, which constitute heating
chambers, which are situated between vertical flues, or passages, leading respectively
from the burner chamber, situated at the base of the stove, and from the horizontal
heating chamber; which leads to a crown space, at the summit of the stove.
In ordinary lamp stoves, the lamp is elevated above the base, and the heat and
products of combustion given off from the flame of the said lamp, is made to pass up
side heating flues, or spaces, and is from thence, conducted to an exit flue.
According to my invention, I form an upright rectangular shaped chamber, made
up of a series of metallic plates, connected together at their meeting edges, so as to
form an enclosure, which is divided off into compartments, viz. ;-a lower compart-
ment, which is the lamp chamber, and a middle compartiment, which is a heating
chamber; and which said heating chamber, extends to the whole superficial area of
the cross section of the stove; and situated within the crown of the stove, is another
compartment, wherein the heat after circulating through the system, as hereinafter
described, is conducted; and from thence, passes away, through back openings, or
piercings, into the atmosphere.
Connected with the lower, middle, and upper horizontal chambers, are vertical
passages, respectively leading from the lamp chamber, into the middle heating
chamber, and two vertical passages, directed from the said heating chamber, into the
crown chamber, and which said last named passages; are arranged at suitable distances
apart, and at short distances from the sides."
The top of the stove, is provided with holes or openings, with lids, through which,
culinary vessels, are placed for heating or boiling purposes, and which said holes,
preferably come opposite the upward passages; so that on a vessel being placed within
one of the said passages, its partial choking, in no way interferes with the proper
circulation of the heat.
The lower vertical passage, whereunder a lamp is placed, is situated at a short
distance from one of the sides, and may come opposite one of the said upper vertical

page_text: The intervening spaces, between the horizontal heating chambers, or shallow spaces,
and vertical passages or flues, are ovens, or baking or heating compartments.
Thus, the heat and products of combustion given off from the lamp, passes vertically
upwards, through the divisional flue, into the middle and shallow heating chamber,
and from thence, circulates up one or both of the vertical flues, into the crown
chamber, or direct through holes or piercings, in the back of the stove.
The regenerative principles, upon which the stove is constructed, destroys or renders
harmless, the products of combustion, given off therefrom.
I will now proceed to describe with reference to the accompanying drawings, the
manner in which the same is to be performed.
Figure 1 represents in vertical section, a lamp cooking stove, constructed according
to my invention. It will be seen that the lid and the flue stopper, on its underside,
are placed in their respective positions, over the circular opening, in the top of the
stove, and in the open top end, of the primary flue, respectively.
By the closing of the upper end of the primary flue, it will also be seen, that the
heat and products of combustion, given off from the lamp, which is shown in elevation,
is made to circulate in a circuitous manner, through the vertical and horizontal flue
systems, before it is discharged into the atmosphere.
Figure 2 also represents a longitudinal vertical section of the said stove, but taken
upon the dotted lines A B figure 1, which is a sectional view taken at right angles to
the said figure 1.
Figure represents a top side view of the stove, with that portion of its top, which
is situated above the supplementary flue, broken away, while that part, and the
utensil opening, coming above the primary flue, is shown in elevation, with the
combined lid and flue stopper, removed.
Figure 4 represents a side elevation of the lid, (which is circular) with flue
stopper.
Figure 5 represents a modified form of my invention, in which two primary flues
are employed, instead of one.
The same letters of reference, indicate corresponding parts in figures 1 to 4.
a is a main vertical flue or passage, with its lower end a², presented a little above
the top of a lamp b, disposed within an open-sided lamp chainber c, and with the oil
tank of the said lamp, resting upon the top or platform part of the base d. e is a
horizontal flue or heating chamber, of the transverse section of the inside of the stove;
and leading upwardly from one end of the said chamber, and near to one of the inside
walls, is a supplementary flue or upright passage, whose upper end 2, empties itself
into a crown heating chamber, whose transverse superficial area, is the same as that
of the lower chamber e. is an upper oven, and is a lower one, which are divided
off vertically, by the horizontal flue e, whose top and bottom sides, form the floor to
the oven h, and the roof to the oven i, respectively, whilst the floor of the oven i, is
made by the roof to the chamber c, and the roof to the chamber h, by the floor, to the
chamber or passage g, wherein both the vertical flues a and f, empty themselves.
The roof, to the passage, is made, by the top of the oven, wherein a circular
opening is made, wherethrough the lower part of a culinary utensil is placed, and
whose bottom comes upon the rests j. k is a lid or cover, with a stopper / upon its
underside, which fits or takes into the open upper end of the fluc a, so as to stop off
heat and products of combustion, from passing directly to the crown chamber J. It
will be observed, that the outside walls form the sides to the ovens, whilst the tops and
bottoms of the flues, form the tops and bottoms to the ovens.
When the bottom of a culinary vessel is placed within the opening j, the heat and
products of combustion, pass up the flue a, and part up the flue, into the crown
chamber g, from whence it escapes into the atmosphere, through the holes or
piercings g.
When the stove is required to be used principally for cooking purposes, other than
boiling, then the combined lid and stopper k, l, is placed in the position as represented
in figure 1, thus, compelling the heated air and products of combustion, to pass first
up the lower portion of the flue a, then along the horizontal passage or flue e, up the

page_text: upplementary flue f, and then into the crown flue g, from which it escapes througn
he holes g'.
In figure 5, the stove is shown with two primary flues, and a supplementary
middle flue.
h is an upper chamber, and i is a lower chamber, divided off horizontally, by a
horizontal flue e, which has leading therefrom, primary vertical flues a, a, and a
supplementary fluef, which all empty themselves into the crown flue g, which has
culinary vessel holes, which come immediately above the tops of the flues a and a¹.
The front of the stove, or the fronts of the ovens, are enclosed by a hinged door m,
which has a sight hole m², at its lower part; and which sight hole m², is in front of,
and coincident with a back sight hole m³, through which the lamp is viewed.
The application of my invention to gas cooking stoves, differs only in using a gas
jet or jets, instead of an oil lamp or lamps.
