Improvements in and relating to Ovens Heated with Oil Stoves.
EDWIN CHARLES RIBBANS No. 117 Fore Street, Ipswich, Sheet-metal Worker
and Ironmonger. I do hereby declare the nature of this invention to be as
follows:-
My improvement consists of a method in constructing an oven to be heated with
oil stoves known as Beatrice,"
""Sunbeam" and others of a similar type.

In constructing the oven I make two cases in shape either square, rectangular,
or D form, one being smaller than the other, thus allowing space marked A. on
drawings (Sheet 1) which is packed with asbestos or other suitable non-conductor,
at top, bottom, sides & back excepting at apertures, D & G shewn on plan, the
front being left for door.
outer case,
The oven is an inner case B and is made of a size giving space indicated by C,
for the heat from stove & products of combustion to pass around. At bottom of
I form an aperture or aperture G (which I have made oblong but it can
be made of other shapes as the forin is not essential) this is to admit the heat and
products of combustion to pass through onto bottom of case marked B, up each
side, over top, and down of flue formed at back passing into the atmosphere at
small hole or holes marked D. The oven would be placed on or above stove but
for security of standing I form two legs bent at right angles & jointed at end so
that they may be folded for packing purposes close to oven, these are marked H.
I also construct these ovens with hot plates as shewn on Fig. 2. Sheet 1, this is
done by extending the base and compartments to length as desired, if for single
hot plate the aperture at bottom for heat etc., is placed at a point near oven
marked G, opposite & above another aperture is formed marked F, this is encircled
by an asbestos cushion a vessel placed upon which seals the aperture, the heat from
stove passes direct through aperture G onto the bottom of vessel placed over
aperture F, and then passes into & around flue marked C, which for only one stove
is blocked at point marked K, thus causing the heat to pass under bottom around
side farthest from stove, over the top & out at opening D near bottom at side
nearest hot plate. In cases of two hot plates, the heat is passed in same way as
described in Fig. 1, the essential feature being that exhausted heat is carried out
at the lowest possible point, position being of no importance.
I construct the ovens of sheet iron or other suitable metal.

EDWIN CHARLES RIBBANS Sheet Metal Worker and Hardware Dealer
114-115-117 Fore Street Ipswich Suffolk. I 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 :--
My improvement consists of a method of constructing ovens, heated by oil
stoves.
It consists essentially of an inner casing A forming the oven and surrounded by
the hot air flues B G D E, this inner casing is shown rectangular but may be made
any other convenient shape.
Sheet 1 shows the arrangement of oven when applied to an oil stove heated by a
single lamp, Fig. 1 is a longitudinal section and Fig. 2 a transverse section.
The bottom or return flue E is produced beyond the oven on the right of the
figure, so as to form a "hot plate," with an aperture F for placing a pan or other
vessel; this aperture I fit with a ring or cushion G made of asbestos or other
non-conducting material, so that when a pan or other vessel is placed over the
orifice F it is sealed to the passage of the heated gases.
An extended opening H is made in the bottom of flue E (which may be
rectangular or any other convenient shape) so that the lamp may be placed either
under the aperture F or under the vertical flue B as shown. When the stove or
lamp is placed in this position, the products of combustion and the heated air pass
up the vertical flue B and along the top flue C then down the second vertical
flue D and along the bottom flue É here (the gases having parted with the principal
part of their heat) they may escape through the aperture I in the bottom of the
flue E. This aperture may however be dispensed with, and the gases may either
escape through the lamp aperture K or becoming heated by passing over the lamp
rise again through the vertical flue B and thus keep up a continuous circulation.
Above the top Rue C I form an air space or jacket L this space having free
communications with the oven at each side as shown in Fig. 2, in this way the
heating surface of the upper side of the top flue is made effective.
The top, sides & back may be protected by means of an outer casing M filled
with asbestos or other non-conducting material. The door N may also be protected
in the same manner.
The oven & lamp is mounted on a convenient stand as shown in Fig. 1, or may
be provided with suitable legs.
The position of the lamp may be a fixed one, under any suitable part of the
bottom flue E or it may be adjustable by means of a sliding opening over the
aperture H which also fits the top of the lamp. Fig. 3 shows the underside of
the oven with this arrangement attached. A small space is left between the
slide O and the lamp attachment P through which a supply of air may pass &
mingle with gases and obtain thereby a more perfect combustion.
Sheet 2, Figs. 4 & 5. shows an arrangement of oven combined with two "hot
plates" and heated by two oil stoves the heated air and gases passing up each
vertical flue B along the top flue C where they unite and pass down the flue Dat
the back of the oven, to the bottom flue E and either escaping by suitable
apertures in the bottom of this flue or by passing over the flame of the stove, and
mantaining a constant circulation as described in connection with Fig. 1. In this
arrangement I also show air spaces or jackets L at the back of the side flues B B
as well as at the top of the upper flue C. The type of oven shown in Figs. 1 & 2.
can also be arranged with these air spaces or jackets to the side flues.
When ovens alone and not "hot plates" are required, the oil stove or stoves may
be arranged in any convenient position beneath the bottom flue E.

page_text: Having therefore described the nature of my invention I claim as follows.
1. Ovens arranged with flues as described whereby the heated air circulates
round the oven and either escapes at the lowest point or passes again over the
flame of the oil stove and mantaining a constant circulation.
2. A sliding frame fitted to an oil stove, and fitted with an adjustable aperture,.
for varying the position of the flame and regulating the heat.
3. A ring or cushion of asbestos or other non-conducting material so arranged
that a vessel or cover placed thereon will practically seal and opening to the
passage of heated air or gas.
Dated this Fifth day of March 1895.
