page_text: PROVISIONAL SPECIFICATION left by Robert Warry at the Office
of the Commissioners of Patents, with his Petition, on the
2nd September 1871.
I, ROBERT WARRY, of Aldershot, in the County of Hants, do
hereby declare the nature of. the said Invention for "AN IMPROVED
PORTABLE COOKING APPARATUS FOR FIELD AND OTHER PURPOSES," to be as
follows:-
This Invention consists of an improved combination and arrangement
of apparatus for cooking, the same being especially applicable for
cooking and preparing food for troops in the field, whilst it is also
capable of being used for cooking purposes generally,
This apparatus enables the several operations of baking, boiling,
broiling, and steaming to be expeditiously carried on at one and the
same time for a large number of persons, whilst the apparatus itself is
so constructed that it is capable of being packed within a very small
compass for the convenience of transport.
The nature and particulars of this Invention will be understood by
reference to the annexed Drawings.

page_text: Figure 1 is a side elevation of the apparatus; Figure 2 is a front
view, and Figure 3 is an end view thereof; Figure 4 is a plan;
Figure 5 is a section through the centre of the apparatus; Figure 6
is an elevation of the apparatus when closed, and the several parts
packed in the oven herein-after mentioned ready for transport;
Figure 7 is a top plan of the same; Figures 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 18, 19, 20, 21, 22, 23, and 24 are details herein-after referred to.
In these several Figures similar letters are used to indicate the same
parts of the apparatus.
A and A' are the right and left plates of the apparatus; B and B' are
the back plates capable of being expanded and contracted by means of
the slots and studs shewn at 6 in Figure 3. The plate A is provided
with a door a for feeding the upper furnace, as shewn at F, Figure 5.
A³ and A³ are boilers, and A' are steamers fitted on the boiler A². The
steamers being so constructed as to fit inside the boiler A³ when not in
use. The upper part of the latter is constructed with two-hinged pieces,
shewn at b¹, b', in Figure 4; 6' is a door opening into the flue of the
upper furnace, below the chimney, and when the main upper furnace
is not in use a supplementary fire can be employed in this part of the
flue for any heating purpose on a small scale; C is the chimney which
is of a tubular form, and constructed in two parts, one fitting into the
other so as to be readily connected and disconnected, and also capable of
being lifted out and placed within the boiler A³; D is the oven, forming
the lower portion of the apparatus, which is raised from the ground by
means of two cross bars d, d, which respectively take into a slot d³, and
bracket ď, a sufficient space being thus left for a flue to pass between
the end of the oven and the back plate B, and which flue communicates
with the upper furnace F, and passes under a hinged folding plate f,
provided with a grating or perforated fire plate, upon which the upper
fire is placed, and through which the smoke and products of combustion
from the lower fire pass, and are consumed. The plate G, which carries
the chimney C, is constructed as shewn in detail at Figures 15 to 18,
and connected with bracket pieces g¹ to the back plates B and B¹.
The oven door D¹ is hinged at the bottom, and is provided with a hasp
and staple (d) arrangement for securing the whole apparatus when packed.
It is also provided with handles d' for conveniently carrying the same.
The door plate H of the upper furnace is hinged to the upper side of
the oven, as shewn at h, Figures 5 and 6; and when brought to the

page_text: position shewn in Figure 2 is held thereto by means of studs and slots,
the former being on the plate H, and the latter in the return ends of the
plates A and A'..
It will be readily seen from the Drawings that the whole apparatus is
readily connected by means of bars, brackets, and bracket pieces shewn
in the details, of which Figures 8, 9, 10, are views of the back plates B
and B'; Figure 11 is an outside view of the plates A and A', and
Figure 12 is an inside view of the same. In these Figures the notch a¹
is for the purpose of receiving the cross bar a³, shewn in Figures 19 and
20, and upon which the boilers rest; Figure 13 is an edge plan view of
one of the plates; Figure 14 is the hinged plate provided with the
grating for the upper furnace, and which forms the flue; Figures 15,
16, 17, and 18 are views of the cross plate G, which carries the
chimney O, the construction of which will be readily understood;
Figures 19, 21, and 23 are views of the cross connecting bars, and
Figures 20, 22, and 24 are cross sections of the same.
