PORTABLE-COOKER ARRANGEMENT.
Specification of Letters Patent.
Patented Sept. 28, 1920.
Application filed July 3, 1916. Serial No. 107,480.
To aZZ a ham it may concern Be it known that I, FRANZ Kniienn tailor citizen of Germany, subject of the King of Prussia and Emperor of Germany, residing at Berlin, in the Kingdom of Prussia and Empire of Germany, have invented new and useful Improvements in Portable-Cooker Arrangements, of which the following is a specification.
The present invention relates to improvements in portable cooker arrangements, in which a heating chamber is combined with the food vessel. According to the present invention the heating chamber into which the fuel is placed, is long shape and extends across the lower part of the cooker, and is provided at one end with an air supply, a chimney leading to the upper edge of the cooker being arranged at the opposite end at an angle to the longitudinal extension of the cooker. By this arrangement the combustion air will always flow through the heating chamber in a longitudinal direction to thesame and with a strong draft, and that the direction of this draft may also be reversed, so that, under circumstances, the chimney will serve as air supply and the air supply orifice as exhaust for the burnt gases. The arrangement according to the present invention allows of employing the cooker also with such fuels, which require a strong draft for their combustion, while the cooker is in any position. The said cooker therefore allows of cooking or heating food during journeys, for example, by travelers in walking or soldiers on the march, the cooker may be used with any possible fuel which may be obtained inthe remotest places, and its operation will not beimpaired by vibrations, shocks or any change in its position.
The present invention differs by the peculiar arrangement of the heating chamber and the chimney, from other portable cookers, in which the passage for the air and that for the gases respectively are disposed beside each other and open both in the upper part of the apparatus. With such apparatus the mouth of both passages heats to the same degree, wherefore no permanent draft can be maintained through the combustion chamber proper. Furthermore only a small part of the fuel in such heating chambers is supplied with combustion air, as the draft does not traverse its entire length, so that the fire will go out after it has been burning a short while only. The present invention also differs from the known pocket stoves, which are operated with solid fuels, essentially'in that the chimney is arranged at a right angle to the longitudinal extension of the chamber and at one end of the latter, so that a permanent strong draft is maintained through the fuel. For obtaining this effect it is necessary that the air supply orifice is disposed at the one end, the chimney at the other end of the long heating chamber. If,
as it is the case with other known cookers,-
the air supply orifices are disposed around the periphery of the heating chamber, it will not be possible to secure a permanent draft through the chimney at all positions of the cooker, whether the same be disposed in the center or whether there be several chimneys disposed at the side.
The cooker according to the present invention is preferably made of such a shape that it may be carried either on a shoulder strap, or may be lashed to the knapsack or the ruck-sack, or be attached in any other suitable manner.
In the accompanying drawings, in which similar reference characters correspond with similar parts in the several views,
Figure l is a vertical sectional view, the section being taken along the line 1-1 of Fig. 2.
Fig. 2 is a horizontal section, the section being taken along the line 22 of Fig. 1.
Fig. 3 is a sectional detail View illustrating the connection of one of the fuel burners with the food container, outer chamber and screw cap or closing member. Figs. 1 and 2 show the cooker of a shape, adapted for the preparing of food during a march.
In the constructional form shown in Fig. 1 inlongitudinal section and in Fig. 2 in cross section, the cooker consists of a body a of a pea-shaped section, which is preferably m ade with double walls, having a suitable insulating material 7) such as kieselguhr, wool, paper or the like packed between the said double walls. The vessel may, however, also be made with single walls and may be protected against radiation of the heat by being covered or coated with a heat insulating means or material. The cooking vessel consists of a metal vessel 0 with a bottom 41. At the one side of this vessel is disposed a passage 7, which, is formed by an indent in the one wall 6 of the of wire netting or a perforated cap f.
vessel, and. which, at the upper end. of the body a, leads out into the atmosphere. The. opening is preferably coveredwith a.,p1e1(;'e T e heating chamber, which is disposed; in, the
lower part of the body, is supplied with solidfuel, preferably the kind of coal known as compressed fuel. This fuel is preferably disposed in such a manner; in a tube or drawer 9 made of wire netting that said fuel may be. conveniently supplied from outside through an opening in the wall ofthezbody.
hisopening is osedy me ns of a s rew cap it which, preferably contains holes 1' and 7a, the width of which may be varied, and
which. may s r e. or. upp ying h 16 8.- sary=air-or'eventually for carrying off; the
combustion gases--. n e c s ructiona form shown these holes are; disposed; at.
theside of, the caph. Ashorttubeg. provided. with, a; male thread, is here provided for introducing. the tube 9 of wire netting andthe fuel, and contains a series ofiholes, which. correspond. With..p rf0 a 1 ns he.
screw caph, which hastheshape of a. cup. Asmay be seen from Fig. 2,- similar ad+ justable air supply. orifices are provided in the face of: the cap; The cooking. vessel,
proper 0 is closed by means .ofcalid Z, which closes. in a liquid: tight. manner. In; this lid: Z is, provided a. spring. pressed; valve m,
which Will? open when the pressure within the: cooking-vessel reaches a certain degree.
In-..,the, constructional. formzshowmthe joint.
between the lid and the vessel. lSnObtitlIlQid by means of roove; 0;. having an. elastic packing, for; examplea rubber ring a. The
lid is secured; in its: position by means, of

I thehook p will be, secured in its locking position, when thecooker. is carried by the straps, or whentby'any. othermeans' an upward pull is exerted onthe lever r;
In the constructional gform-shown in Figs. 14 and 2 heating tubes :areprovided beside each other, said tubes being disposed on .op-
posite sides-of the,- centerline. of the chamber so. that there willlalways. :beianup idraft form may. bevaried-in various ways without departing from the principle of the present invention.
The cooker according to the present inventionf affordsthe advantage that food which has been placed into the cooker beforehand, may be cooked during the march. The-ownerof such cooker, may, therefore, enjoy his meal. as. soon as. he reaches his halt, without having to wait and cook his food. Any shocks. .produ ced during the marchwill not affectthe operation of the cooker, on, the, contrary, such shocks may. evelrliave afavorable effecton theiheating arrangement.
