' (Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 O. G. 757) 6 Claims.

The invention described herein may be manufactured and used by or for the Government of the United States for governmental purposes without the payment to me of any royalty thereon in accordance with the provisions of the Act of April 30, 1928 (Ch. 460, 45 Stat. L. 467).

My invention relates to stoves and particu- *larly to one adapted to heat a single Army field with "solidified alcohol in which the flame is exposed to cross currents of air which deflect the heat from the vessel being heated, thus wasting heat, while gusts of wind often extinguish the flame. Prior stoves also emit light which may reveal to the enemy the location of a soldier.

My stove is designed to overcome both of these defects.

In the accompanying drawings:

Figure l is a central longitudinal section of my stove with a canteen cup supported therein;

Figure 2 is a similar view with the parts telescoped;

Figure 3 is a section on line 3-3 of Figure 1;

Figure 4 is a detail of one of my supports, the folded position of which is indicated in dotted lines;

Figure 5 is a fragmentary perspective view of my sleeve and one support.

In these drawings:

An inner sleeve II is downwardly tapered and is curved in transverse section to correspond with the taper and curvature of a standard army canteen cup I2 modified by an outwardly extending bulge It to receive a folding handle I4 of the cup in full lines for clearness of illustration. The sleeve l I is provided with a plurality of slots l5 in each of which is mounted a folding support l6 having an inwardly extending lug I! provided with a spacing ofiset I8 for supporting the cup and an outwardly extending lug l9 provided with a spacing offset for supporting said inner sleeve on the upper margin of an outer sleeve 2| which has the same taper and curvature as those of the inner sleeve l I, and a bulge 22 corresponding to the bulge I 3. The support I6 is also provided with one or more securing lugs 23 which are initially bent to permit the support to enter the slot l5 and afterwards straightened to retain the support in the sleeve II.

A source of heat 24 may be a can of solidified alcohol, a fuel briquette or the like.

The operation of my stove is as follows:

The fuel is placed within the outer sleeve 2| and ignited; the inner sleeve I l, with the supports I6 in operative position, is lowered into the outer sleeve until the outwardly extending lugs l9 engage the upper margin of the outer sleeve 2| when, due to the tapering of the sleeves and the spacing offsets 20, there is left a relatively narrow inlet flue 25 for a down draft air supply to the burning fuel. The drinking cup I2 containing food to be heated is placed within the inner sleeve I I on the supporting lugs I1 and is spaced therefrom by the offsets I8, thus providing a flue 26 for the escape of the hot products of combustion along the sides of the cup, thereby imparting heat directly thereto while the heating of the inner sleeve II serves to preheat the air passing downwardly through the flue 25.

My ration heating stove has no horizontal holes or apertures through which rays of light may be emitted or gusts of wind deflect heat from the receptacle or even extinguish the flame.

It should be understood that the present disclosure is for the purpose of illustration only, and that the invention includes all modifications and equivalents which fall within the scope of the appended claims.

What I claim is:

1. A stove of the class described the combination of a plurality of separable tapered sleeves adapted to telescopically fit over a canteen cup, a plurality of hinged supports intermediate the ends of and mounted on an inner one of said sleeves each having a lug adapted to support said *inner sleeve on and in spaced relation to an outer sleeve and also a' second lug to provide a support within said second sleeve for a receptacle and to hold said supported receptacle spaced therefrom.

2. In a camp stove of the class described, the combination with an inner tapered sleeve, a plurality of foldable supports mounted in said sleeve each having an inwardly extending spacing offset and supporting lug and an oppositely extending spacing offset and supporting lug and an outer sleeve conforming to the shape and taper of said inner sleeve adapted to engage said foldable supports and thereby hold said inner sleeve in an elevated position.

3. In a camp stove of a type which utilizes solidified alcohol, the combination with an inner tapered sleeve provided with a plurality of transverse slots intermediate of and equally distant from one edge of the sleeve, a folding support having an outwardly extending lug and an outwardly extending spacing offset and an inwardly extending lug combined with a spacing ofiset mounted in each of said slots, and an outer sleeve conforming to the taper and curvature of said inner sleeve adapted to support said inner sleeve when said folclablesupports are extended.

4. Inaoampstove of the itype described,'the combination with an inner sleeve conforming to the curvature of a standard canteen cup modified by a bulge to enclose a folded handle, a plurality of foldable supports mounted in said sleeve equally distant from one edge each having an inwardly extending supporting lug combined with aspacing offset and an oppositely extending supporting lug combined with a spacing offset and an outer sleeve conforming to the taper'andshape of-said inner sleeve adapted to support said inner sleeve when said foldable supports are extended.

5. In a camp stove of a type which utilizes-solidifid alcohol, the combination with an inner sleeve conforming to the curvature of a standard canteen cup-moclified by a, bulge to-enclose'a folded :cup handle, a plurality of foldable supports :mounted in said sleeve equally distant from one edge, each support having an inwardly extending lug-andspacing oifsetwand an cutwarcllyexitending lug and spacing offset and an outer sleeve ricoriformingto the curvature of saidinner sleeve :adapted to support said inner sleeve when said ifoldable supports are extended.

"6. A stove comprisinga plurality of. substantiallyicon-centricsleeves toaccommodate a receptacle, and fa cheatingelement'separate from the sleeves and "receptacle, a plurality ,of pivoted spacing 'elementsbeing mounted in'one of said sleeves and provided with oppositely positioned lugs, one of 4 which lugs serves to support an inner sleeve in elevated position relative to the outer sleeve and spaced therefrom, and the other of said lugs supports said receptacle on an outer sleeve in an elevated position and spacedfrom saidsleeve to per- "mit heat i'fromthe heating element to draw in air from the space between the sleeves and to heat the air as it passes to and around the receptacle.
