Improvements in Portable Cooking Stoves and Utensils.
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 to
be as follows:-
My invention relates to cooking stoves and utensils specially adapted for use by
military men or travellers, in tents or waggons as well as in the open air. A stove
according to my invention is divided into three compartments or storeys of ovens by
horizontal flues which form separate communications from a vertical flue on the one
side, say the left, to a vertical flue on the other side, the right, each of these horizontal
flues being provided with a valve or damper by which the draught through it can be
regulated as desired. The uppermost compartment is divided by a vertical partition
through the upper part of which there is a grated opening.
On the right side of the partition is the fire place, on the left is an oven over which
pass the hot products of combustion from the fire on their way to the vertical flue on
the left along which they descend. From this vertical flue the products pass by the
several horizontal flues to the vertical flue on the right, up which they ascend to the
chimney, the products thus heating on their way the two storeys of ovens over
and under which the horizontal flues are formed. On the top plate of the stove
are placed boilers, preferably of rectangular form, and similar boilers or cooking
vessels or dishes can be placed in the several ovens.
In order to prevent the liquid contents of the boilers or cooking vessels from
splashing out, to which they would be liable when the stove is worked in a travelling
wagon, I form around the top edge of the vessel an internal trough, and I provide the
lid with two deep ribs projecting down from it, the one rib projecting down into
the trough nearly to its bottom and the other rib projecting down just inside the
inner wall of the trough. These ribs in conjunction with the trough prevent liquid
from splashing out of the vessel notwithstanding considerable agitation.

Improvements in Portable Cooking Stoves and Utensils.
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 :-
My invention relates to cooking stoves and utensils specially adapted for use by
military men or travellers, in tents or wagons, as well as in the open air, as I shall
describe referring to the accompanying drawings.
Fig. 1 is a vertical section of a stove according to my invention and Fig. 2 is a
perspective view to an enlarged scale shewing part of the upper edge of one of
the stove boilers with provision against spilling the contents when the stove is
shaken by the movements of the wagon on which it may be carried.
From the fire F which is situated in the upper part of the stove the hot products
of combustion pass across by the flue C down the flue C, back by cross flues C³
to the chimney Cheating several ovens F¹ in which are cooking pans or vessels B².
On the top of the stove are placed boilers K, each of which, as shewn in Fig. 2,
is made near its upper edge with an outward bulge or corrugation n and above it

page_text: with two walls p forming a trough, the inner wall of which p' is perforated
with numerous holes allowing such liquid as may enter the trough to flow back
into the boiler. The cover of the boiler has two lips projecting down from it,
the outer lip entering the trough between p and p' and the inner lip extending
down within pl.
Should the liquid contents of the boiler be agitated, the waves are arrested by the
lips of the cover, and the sides of the trough so that none of the liquid is spilled.
At the back and sides of the stove there is a water casing R which protects against
fire combustible material in the neighbourhood of the stove.
any
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A portable cooking apparatus consisting of fire place F, flues CC1 C³,
chimney C², ovens F¹ and boilers K in combination with water casing R, substantially
as described.
2. A boiler used for portable cooking apparatus having its upper edge formed as a
trough in combination with a cover having two downwardly projecting lips, substantially
as and for the purpose set forth.
