PROVISIONAL SPECIFICATION.
Improvements in Oil Cooking Stoves and in Utensils for
use therewith.
1, REUBEN DAY, of Highbridge in the County of Somerset, General Dealer, do
hereby declare the nature of this invention to be as follows:-
This invention refers to improvements in oil cooking stoves, whereby several
ovens may be used simultaneously, or only one or more of such ovens may be used
separately, all as desired, and when the stoves are fitted with boilers, one separately
or more of such may also be employed; the invention also refers to cooking
utensils, whereby one, two, or more steamers or boilers may be heated over one
top aperture of the stove.
According to my invention, I provide a casing of sheet metal raised and
supported upon legs of suitable height which may be adjustable. Upon cross bars
situated near the lower ends of the legs I fit one or more shelves or platforms
capable of being slidden horizontally, such platform or platforms being intended
to carry the lamps from which the heat is derived. Within the casing and having
a door opening on the exterior of same, I fit an oven, and also in some cases a
boiler at the side thereof, and in this connection, there may for example be two
lamps, each on a sliding platform, and these lamps may be slidden so as to both
heat the oven or boiler, or one to act for the oven and the other for the boiler, all
according as is required by circumstances. The heat passes around and over the
oven, and escapes by apertures at the lower or upper part of the side or sides or at
the top. In-some cases I may provide a plate at the base of the outer casing to
prevent cold air passing around the oven or ovens. The oven may in some cases
be arranged in the middle and a boiler at each side, or there may be two ovens
having a boiler between same, or two ovens having a boiler centrally and at each
end the boilers should be provided with taps and usual fittings.
There are as
many sliding platforms as there are lamps required. The outer metal casing
extends below the bases of ovens and boilers, and has or may have an aperture at
the top to receive a kettle or cooking or boiling device.
According to my invention I construct a casing, say, of cylindrical form, standing
vertically, being open at the base, and fitted with a boiler at its upper part, the
casing being made to fit the aperture in the top of the stove casing; in the top of
the boiler fitted within the cylindrical casing, I form apertures, into which may be
fitted vessels for steam cooking. The upper part of the outer cylindrical casing
may be formed with apertures for escape of products of combustion. The cooking
vessels may have perforated bottoms, whereby the contents may be either boiled or
steamed. The boiler and steamers can be removed when desired, and replaced by,
say, a kettle. Such vessels to be used for steaming or boiling may be applied to
the fixed boilers beside the ovens.
The ovens are fitted interiorly as usual with shelves, and also are provided with
ventilating devices, and when the boiling appliances are being used, the air escape
apertures in the casing may be closed, and the heat be caused to travel through
the cylindrical or other shaped casing of such appliances.

Improvements in Oil Cooking Stoves and in Utensils for
use therewith.
I, REUBEN DAY, of Highbridge in the County of Somerset General Dealer
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 refers to improvements in oil cooking stoves whereby an oven
and a boiler may be contained in the same casing, or two or more ovens may be
therein contained and the boiler dispensed with, all as desired, while the heating
devices, such as paraffin lamps, are arranged below such casing and more advan-
tageously and conveniently than heretofore. The invention also refers to cooking
utensils whereby one, two, or more steamers or boilers may be heated over one
top aperture of the stove.
In order that my invention may be properly understood, I will describe same
with reference to the accompanying drawings, wherein
Figure shews in vertical longitudinal section a stove constructed according to
my said invention, Fig. 2 being a transverse section of the upper part of same and
Fig. 3 a perspective view of the sanie stove;
Fig. 4 shews in section a modified arrangement, and Figs. 5, 6, 7, 8 and 9 shew
utensils hereafter described, Figs. 10 to 16 illustrating utensils and devices
hereafter referred to.
According to my invention I provide a casing A of sheet metal, Figs. 1, 2 and 3,
raised and supported upon legs B of suitable height, and if desired the legs may be
provided with wheels or castors at their lower ends. These legs are preferably
tubular and take into sockets A' A' upon the casing A so that the latter may be
removed from the legs B for cleaning and be readily replaced by the handles A**
attached to the ends of the casing A.. If desired the legs may be made telescopic
(although not so shewn in the drawing) and the height of the stove be thus made
adjustable. Upon the crossbars CCI fit a platform C capable of adjustment by
being slidden vertically, such platform or platforms C', being intended to carry the
lamps D from which the heat is derived; these lamps marked D may be of any
ordinary or well known construction, and be provided with chimneys or not, all as
desired, those shewn in the drawing being merely to indicate the position thereof.
The rods C C which support the platform C₁, enter slots B¹ in the legs B and
are then carried upon vertical spiral springs B2, Fig. 1, located within the said
legs and bearing at the base of the slots upon cross rods C2; C³ are cross plates
fixed to the legs B. G G are catches formed of spring metal and slotted to receive
studs G G2, Fig. 3, from the crossplates C³, and the cross rods C² respectively;
the hooks of the catches G G are adapted to take over the rods C of the
platform C. Within the casing A and having a door E' opening on the exterior
of same, I fit an oven E, having a ventilator as desired and provided with a shelf
or shelves, and also in some cases (as illustrated at Figs. 1, 2, and 3) a boiler Fat
the side thereof, the oven door E¹ being supported when open on a bracket E² fixed
to the case as shewn, or otherwise fixed to the said oven door. The boiler does
not extend to the interior sides of the casing A, but may be provided with a tube
and an exterior tap F on the outside, Fig. 3; the casing A extends below the
oven and boiler and is fitted with rods A*, Figs. 1 and 2, extending across the lower
part thereof, and at Fig. 1 the lamp is shewn in position as when alight, being held
up against the rods A by the pressure of the spiral springs B. When the lamp is
to be lowered for lighting, trimming, or otherwise, the handles C at the ends of
the platform C' are pressed down, until the catches G G take over the bars CC of
the platform as at Fig. 3, and the lamp or lamps are held in a convenient position.

page_text: After lighting, the catches are simultaneously released by the operator, and the
springs carry same automatically into the position Fig. 1.
It is necessary to be able to vary the tension of the springs B2, should a heavier
or lighter lamp be placed upon the platform, thus for example, should the springs
not be sufficiently powerful to carry the lamp or lamps into position (Fig. 1) the
fly-nuts GG are loosened, the crossbars C² raised (compressing the springs B²),
and the fly-nuts G G again secured; again, should it be desired to have the
platform held in a lower position than that shewn at Fig. 3, say in order to suit a
lamp, with or without a flue, of some other construction, the catches G G may be
moved and secured in a lower position, as will be well understood.
In the top of the casing À I form a series of holes H, and the heat after
circulating entirely around the base, sides, and ends of the boiler F and around the
base, sides, and top of the oven E, or at the back between the oven and casing,
passes through the said apertures H, and heats whatever utensil is placed thereon,
and carrying the whole of the heat through the utensils hereafter described. Upon
the open top of the boiler may either be placed a suitable cover, or.a utensil, such
as J, Fig. 1, with a perforated bottom for steaming purposes.
In some cases I may provide a plate at the base of the outer casing to prevent
cold air passing around the oven or ovens.
The oven may in some cases be arranged in the middle and a boiler at each side,
or there may be two ovens having a boiler between same, or two ovens having a
boiler centrally and at each end; the boilers should be provided with taps and
usual fittings. At Fig. 4 is shewn an example where the oven E is arranged in the
lower part of the casing A, and the boiler F above the oven as will be readily
understood from an inspection of the said Fig. 4.
I
I construct the cooking utensils with outer casings K, Figs. 5 to 8, say, of
cylindrical form standing vertically, being open at the bases thereof and fitted with,
say a frying pan as at Fig. 5, a kettle Fig. 6, or a saucepan as at Figs. 7 and 8, or
other utensils, within the upper parts of the said cylinders, and so formed that the
tops of the cylinders are closed thereby, while the utensils stand clear of the interior
sides, and allow the heat to escape, as at Fig. 5, by apertures K', around the sides
of the cylinder K. The boiler may be fitted with one or more divisions.
generally fit about centrally within the utensil proper a tubular passage or
passages L, whereby the heated products may pass entirely through the said
utensils, and the lids of such utensils, as shewn at Figs. 6 and 9, are formed with a
suitable aperture or apertures to allow of the passage therethrough of the tubular
parts L. By these devices the heating surfaces are greatly increased, and further
advantages are presented, in that one utensil may be placed upon the top of another
and both heated, thus the kettle, Fig. 6, may be placed upon the top of the sauce-
pan, and if desired the frying pan Fig. 5 upon the top of the kettle, and the heat
pass throughout all the appliances. The tubular parts L may be of any shape or
dimensions.
Utensils such as described may be advantageously employed upon any ordinary
oil, gas, or spirit stove, and by my invention several such utensils may be heated
simultaneously over one such stove.
Figs. 10 and 11 shew in section and perspective views a utensil (in this case a
kettle) having a ring-shaped equivalent of the outer casing K applied to the top
thereof, L being the tubular passage within the utensil fitted with cover to regulate
the heat. The ring-shaped casing Kis pierced with holes and a separate cover K*
may be applied to the utensil through which cover the tube L passes, and allows of
other utensils, such as a frying pan or saucepan, being placed upon the ring K
and heated.
In order to adapt an ordinary lamp stove or stoves to be conveniently used, to
heat the various contrivances, constructed according to my invention, I arrange
such stoves as shewn at Fig. 12 with a ring M somewhat lower than the top of the
flue or chimney, and upon the ring I place such a plate or false bottom N as is
shewn at Fig. 13, and when so placed the flue projects slightly through the

page_text: aperture in the plate N, so that, the latter resting upon the ring M, utensils such
as have been herein before described may be placed upon the plate or false
bottom N, and the whole of the heat will pass through the utensils or the like,
while no cold air can enter same.
At Figs. 1 and 3.of the drawings the stove casing is shewn upon a stand, and it
has been stated that it may be removed therefrom but I would have it understood that
such stove casings may be employed with or without such stands, and over such
ordinary stove or stoves as shewn at Fig. 12, the plate N Fig. 13, being then made
of a size suitable for the casing to stand upon. In some cases two or more such
stoves may be used together, as at Fig. 14, where the plate N is adapted to rest
upon both, and an oven casing, such as shewn at Fig. 15, and a boiler and steamer,
as at Fig. 16, may be placed thereon, or the oven and boiler casing shewn at
Figs. 1, 2, and 3 may be similarly applied. Even when the oven and boiler casing
is used with the stand or legs, two lainps such as at Figs. 12 and 14 with the false
bottom N can be put on the platform. C Figs. 1, 2 and 3, and raised with the
lamps to the bottom of the oven and boiler casing, and the entrance of cold air
thereby excluded.
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 oil cooking stoves wherein an oven and boiler are contained in a bottomless
casing, a lamp for heating same supported on an adjustable spring-actuated plat-
form, the latter being kept in either of two positions whereby the position of the
lamp may be regulated, in combination with devices for holding the said platform in
position, all constructed, arranged, and acting substantially in the manner and for
the purposes set forth, and described with reference to Figs. 1, 2, 3 and 4 of the
accompanying drawings.
2. The cooking utensils constructed and arranged as described with reference to
Figs. 5, 6, 7, 8 and 9, in combination with such stoves as are claimed with reference
to Claim !.
3. In oil cooking stoves and appliances therefor, the combination of a stove or
stoves having supporting devices M in combination with the false bottoms or
plates N all acting substantially as and for the purposes herein set forth.
