Improvements in Cooking Stoves.
I, ALFRED SAVILL TOMKINS, of Holmwood, Caterham, in the County of Surrey,
Captain in the Victoria Rifles, 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 an improved construction of cooking stoves which
I will describe with reference to the accompanying drawings in which Fig. 1
shews a part sectional plan Fig. 2 a part side view and part longitudinal section
Fig. 3 an end view Fig. 4 a cross section on line - Fig. 3, Figs. 5 and 6
detached details, and Figs. 7 and 8 a part longitudinal and part cross section of
a modified construction.
The cooking stove is somewhat similar in construction to the portable cooking
stove described in the Specification to Patent No. 24108 in that there are two
rows of metal ovens arranged one on each side of a central fire-place and flue,
but the present construction is considerably modified in that the flames and hot
gases are first made to pass from the furnace into flues running underneath each
row of ovens and then into a flue between the two rows, so as to afford a more
perfect utilization of the heat than in the previous construction where for the
sake of portability, there was only provided a single middle flue between the
two rows of ovens.
On each side of the furnace A is built a brickwork structure B B in which
are formed longitudinal flues C, C, with the front end of which the furnace A
communicates through lateral openings D D, while the rear ends communicate
by side openings E E, with a central flue F leading to the chimney G. The
brickwork forming the flues C C, is open at top, the flues being closed in by
the bottoms of the metal ovens H H which are placed over the flues.
Beneath the two ovens on each side nearest the furnace however, firebrick slabs I
are placed on the flues beneath the ovens, in order to protect these against the
greater heat of the flames and gases at that part of the flues.
The first oven on each side is also protected against the heat of the furnace
by fire-brick slabs I¹. The back of the fire-place A is separated from the middle
flue F by a firebrick partition J and the top is also closed in by a firebrick slab 1.
The two sets of ovens H H are secured in position at each end by plates K K¹
shewn separately in front and side view at Figs. 5 and 6 these plates being
formed with slotted holes as shewn, the enlarged lower ends of which are adapted
to fit over studs L fixed on the ends of the ovens so that when the plates K K¹
are slightly lowered the studs are secured in the narrow part of the slots
The front plate K also serves to form the front wall of the upper part of
the furnace and is lined inside with a fire-brick slab. The rear plate h₁.serves
to close the rear end of the middle flue E.
The metal chimney flue G is fixed to the top of the front part of the flue E
and an inclined plate M is fixed in the latter extending from the flue openings E
up to just below the flue G so as to effectually lead the draft up to the latter.
Access is gained to the flues E E through soot doors N. The furnace door O

page_text: is hung with its hooked upper end upon a bar P that is pivotted to the one row
of ovens H and is hooked into a loop on the other row as at Fig. 3, so that
the door can be slid sideways on such bar. The two rows of ovens H are
constructed similar to those described in the Specification to Patent No. 2410
of 1898 each oven being provided with a vertically sliding door Q.
In some cases I combine a steam boiler with the above described cooking stove
as shewn in the modified construction at Figs. 7 and 8, Fig. 7 shewing a part
longitudinal section and Fig. 8 a part cross section at Y Y Fig. 7.
In this case a part of the brickwork back J of the furnace is replaced by a
steam boiler R the upper part of which corresponds in width to the width of
the space between the oven H while the lower part is widened so as to project
under the ovens so as to rest on the brick work B and form part of the sides of
the flues C.
The steam is taken off by a pipe S to wherever required. T is the water
supply pipe.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim
is:.
1. A cooking stove consisting of two ranges of metal ovens mounted on each
side of a furnace upon horizontal flues communicating at one end with the fur-
nace and at the other end with a middle flue situated between the two rows of
ovens and leading to a chimney the two sets of ovens being connected together
at the ends by plates with slotted holes fitting on studs on the end surfaces of
the ovens, substantially as described with reference to Figs. 1 to 6 of the drawings.
2. The combination with a cooking stove such as is referred to in the first
claim of a steam boiler such as R. forming part of the back of the furnace chamber
substantially as described with reference to Figs. 7 and 8 of the drawings.
3. A cooking stove constructed and operating as herein described with reference
to the drawings.
Dated this 15th day of September 1899.
