We, JOHN STOUP CHAMBERS and JAMES GILLMAN SEYMOUR both of
corner of Collins and Swanston Streets, Melbourne, in the Colony of Victoria,
Merchants, do hereby declare the nature of this iuvention to be as follows:-
This invention provides appliances by which a stove lamp or other heating
apparatus is utilized to heat kettles, pots, flat irons and such like articles and
the products of combustion then conducted into and around a chamber containing
materials or food to be heated or cooked. By the arrangement herein described
the heat from the burner is thoroughly expended in heating or cooking such
materials or food before it passes out and away by a chimney.
The invention consists of a stand formed of a rectangular or other shaped plate
supported on suitable legs or framing. This plate is provided with openings
over one of which a chamber or oven is set as hereafter described and above
the other or others a kettle, pot, flat-iron or other such utensils to be heated are
placed. The latter opening or openings may be closed with lids when not
in use.
Beneath and secured to this plate is an inverted pyramidal dish or somewhat
truncated cone-shaped plate forming a box and having an opening at the bottom or
truncated part. The box thus formed acts as a guide to lead the heat fumes from
the burner to the aforesaid openings in the plate.
The oven is designed particularly for use with oil gas burners or stoves. The
stove is placed beneath the stand with its burner projecting into the box afore-
said its position being determined by a slide plate into which it fits. By this
arrangement the hot air or fumes from the burner are conducted directly to
the required openings under the oven and kettle pots &c. as aforesaid without loss,
the direction of the fumes being influenced by the position of the burner and
slide plate.
The chamber or oven, which is set upon the stand has an opening in its bottom
plate to correspond with the opening in the stand plate. The top sides and back
of the chamber or oven have an outer shell which forms with the inner shell a
passage or jacket for the heat fumes. The inner side of the shells of the
chamber have a number of perforations near their top, the inner top plate is also
preferably provided with similar perforations near its front. The heat fumes
whilst heating the kettle &c. are also entering the said chamber and rise within it
and pass through the perforations into the jacket at the sides and top of the
chamber and pass down in the jacket at the back of the oven where an outer
jacket is formed so that the spent fumes conducted down the back will pass by
an opening formed at the bottom of the central back plate along and up this
outer jacket (which serves as a chimney) thus further heating the oven before
being liberated.

We, JOHN STOUP CHAMBERS and JAMES GILLMAN SEYMOUR both of
corner of Collins and Swanston Streets, Melbourne, in the Colony of Victoria,
Merchants, 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 provides apparatus by which kettles, pots, flatirons and such like
articles may be heated and in which the heat fumes instead of passing away after
heating such articles, are conducted into and around a chamber.or oven containing
materials or food to be heated or cooked. By the arrangement herein described
the heat from the burner which is preferably a stove lamp or other portable
heating appliance, is thoroughly expended in heating or cooking such materials or
food before it passes out and away.
In order to make our invention clear we will now refer to the accompanying
drawings in which―
Figure 1 shews a perspective view of the apparatus with the oven door
removed.
Figure 2 shews a cross section.
Figure 3 a longitudinal section, whilst
Figure 4 is a sectional plan of the apparatus.
A represents a stand plate formed of a rectangular or other shaped plate
supported on suitable legs A¹ This plate is provided with openings A', A³.
A specially constructed chamber or oven B is set upon the stand over the
opening A as hereafter described. Kettles, pots, flatirons or other such utensils
to be heated are placed upon the stand and over the opening or openings A³.
These openings A' may be closed with lids when not in use.
Beneath and secured to this plate is an inverted pyramidal dish or somewhat
truncated cone-shaped chamber C forming a box and having an opening C' at the
bottom or truncated part. The box thus formed acts as a guide to lead the heat
fumes from the burner to the aforesaid opening in the stand plate.
The apparatus as aforesaid is designed particularly for use with oil gas burners
or stoves. Such stove is placed beneath the stand with its burner or flame
projecting into the box C, its position being preferably determined by a slide
plate D provided with an opening D'. This plate is arranged to slide in guides
formed by turned in portions C of the box C. The slide plate may be moved so
that the opening D₁ will lie beneath the pot to be heated upon the stand plate as
shewn in Fig. 3, or by sliding the plate to its other extremity the opening will lie
beneath the oven. By this arrangement the hot air or fumes from the burner are
conducted directly to the required openings under the oven or kettle, pots &c. on
the stand plate.
The chamber or oven B which is set upon the stand plate has an opening in its
bottom plate to correspond with the opening A' in the stand plate. The top, sides
and back of the oven have an outer shell F which forms with the inner shell F' a
passage or jacket E for the heat fumes. The inner shells of the sides of the
oven have a number of perforations G near their top, the inner top shell is also
provided with similar perforations G₁near its front. A second outer shell H
is set at the back only of the oven (see Figs. 2 and 4) and an opening J
formed in the shell F near its bottom forms a passage for the fumes into the
chimney K.
The oven may in some cases be provided with a hood or cover L open at its
front and provided with an opening L¹ in its bottom plate.

page_text: The modus operandi of the invention is as follows
The food and other articles to be heated or cooked are placed in receptacles over
the openings A' or on the trays inside the oven B or both. The heat fumes from
the burner placed at any convenient position by the slide plate D in the truncated
chamber C whilst heating the receptacle placed upon the stand plate over the
openings A' also enter the oven B and rise within it in direction shewn by
arrows, and pass through the perforations G and G' and within the jacket E
along the top and down the sides and back of the oven to the opening J in
the shell F and thence up the outer jacket or chimney K whence they may pass
away into the open air, or in some cases first pass through the cover or hood which
serves to retain sufficient heat for the purpose of keeping plates and like articles
warm.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. In combination, a stand plate as A having openings as A2, A³, a chamber
as C and oven as B substantially as and for the purposes set forth.
2. In combination an oven as B whose sides top and back are jacketted, the
inner shells of which have perforations as G, G¹ and the outer shell a perforation
as J, chimney as K, a stand plate as A and chamber as C mounted upon legs as A¹
substantially as and for the purposes set forth.
3. The general combination and arrangement of the whole of the parts.
substantially as described and as illustrated on the accompanying drawings.
