COMPLETE SPECIFICATION.
Improvements in Portable Cooking Apparatus for Military and
other Purposes.
I, MAX DRAKE of No. 10 Kaiser Friedrichstrasse, Schöneberg, near Berlin,
Germany, late Captain in the German Army, 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 :-
Cooking apparatus constructed according to this invention is chiefly characterized
by its peculiar burner by means of which the fuel especially spirits is fully utilized
and great heat effect produced.
Figure 1 of the accompanying drawings is an outside elevation of the cooking
apparatus when out of use and Figure 2 a vertical section shewing it in use.
Figure 3 shews a detail attachment.
The cylindrical body a is by the partition 6 divided in an upper and a lower
compartment, the former being the larger contains the liquid to be boiled, and the
lower compartment being provided with holes c and containing the burner proper.
This burner consists of a removable flanged bottom d provided with holes e and
serving to receive a cord wick for other suitable material by preference consisting
of incombustible material such for instance as asbestos or silica (kieselguhr). This
material is soaked with spirits or other suitable combustible liquid and ignited which
can be be done by a lucifer match put under one of the holes e. The flames strike out
through the numerous holes e and envelope the vessel a. Thus the fuel is utilized
in the best possible manner.
Obviously a great heat effect may in this manner be produced with a small
quantity of spirits or the like. But a great advantage is also gained by the
circumstance that it is hardly possible to supply the burner with a surplus of spirits
which would only uselessly evaporate.
1 is a ring which can slide on the cylinder a and is provided with feet i that may
be rigid or turn on hinge bolts k. When the apparatus is in use the ring is pushed
down so that the feet touch the ground. This ring may suitably be provided with
a hinged handle m, Figure 3, which again may have a second hinge joint for the
purpose of folding up as shewn in dotted lines, so that when the apparatus is out of
use the folded up parts do not protrude beyond the ends of the cylinder a.
The liquid to be boiled or heated may be put directly into the cylinder a or a
bottle filled therewith may be put into water contained in the cylinder a. After
use the ring is pushed upwards and two covers g and are put on the cylinder a
so as to fit it for transport of the liquid boiled therein. This apparatus is especially
suitable for military uses.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. Cooking apparatus characterized by that the heating appliance is so arranged
under the cooking vessel proper that the flames striking out through holes of the
burner envelope the same whereby the fuel is utilized in the most economical, quick
and energetic manner substantially as described and shewn.
