v To all whom it may, concern: I

Be it known that I, GUY W. Fnnoon, a citizen of the United States, residing at Greskill,

invented certain new and useful county of Bergen, State of New Jersey, have Improvements in Collapsible Folding Stoves; and I do hereby declare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to collapsible foldin stoves of a type that may be easlly lmocke down or separated, and one which is adaptedtween oil and denatured alcohol maybe such that under some circumstances, or in some localities, one may be preferable or obtalnable, and-under other circumstances or m other localities, the other. Also my device may be employed in connection with gas, either natural or artificial.

I adapt my burners to the use of any of these fuels by very simple means, which will 7 be explained in detail;

My stove is adapted for ready cleansingand attention, and is readily collapsible, which is of great value in saving wei ht and cubic measurement for shipping an' transportati'on. ,Thestove may also be shipped set up, if desired. I

Fig. 8 is a perspective view of a cap which I use.

Fig. 9 is a sectional view of the same cap, sald cap being used in connection with the kerosene burner.

Figs. 10,11 and 12 are diagrammatic views showing the position of the shelf in outline whenvarious fuels are used.

Fig. 13 indicates the shelf removed, and Fig. 14: is a perspective view of the bracket or shield detached.

In the drawing, 1 indicates the top plate or grate plate of my stove provided with the grates 2, tank 3, fuel supply pipe' l, burners 5, and chimneys 6. The devlce is provided, with a fuel shelf 7, which is shown supplied with bolts 8. These bolts are movable or slidable in slots 9 in the standards or legs 10 of the frame, whereby the fuel shelf may be readily set to any height within the slots, the bolts being supplied with milled nuts 10 for ready adjustment or removal.

v The tank 3 may be removed at 11 by unscrewing the nutted coupling, and attachment be made to a gas supply, if desired. The tank 3 is of the usual type, and is provided with the usual valve 12; when the tank is inserted in place, this valve 12 discharges into a lower fuel tank 13 and is connected by .means of the pipe 4 with the burners. This is a usual construction, and the tank may also be provided with a projection 14, so that when it is inserted it'may rest upon said projection and be kept steady. The two tanks are supported by a bracket 15 and by the fuel supply-pipe. When the tank is in the lowest position, that is, when kerosene is'being burned, two bolts 16, which connect the bracket to the apron or cross piece 17 between the two legs on the right hand, are

passed through registering upper holes in the bracket and cross piece, and these aid in securing the tank in rigid position. When in this position, if the tank is supplied with fuel in the usual way, as soon as t e valves 18 are opened fuel begins to ass to the burners, which I show here as the urners of a vapor burning stove, or, as it is sometimes called, of a blue ame stove,'a match being applied and the burners heated in the usual manner the chimneys 6 soon transmit the usual hot blue flame to the grates 2. v

. I provide the legs 10 with suitable marks 20, to indicate the desired hei ht for diiferent fuels. This aids in easy a justment, and when the shelf is adjusted to the lowest mark 20, the stove supplies the greatest amount of heat to the grates 2, the stove then behaves as an ordinary blue flame kerosene stove, and has all the properties of such a stove in addition to certain other features to be discussed later.

If it is desired to use commercial or denatured alcohol, the fuel shelf is raised and set in the slotted legs at the upper mark 20, and as indicated in Fig. 4. If the stove has been set previously for use with kerosene, the

.. bolts 16, which aflix the lower fuel tank of the bracket to the side of the iece 17, are removed so that the fluid shelf, urners, and supply tank move in unison and to theirnew level of adjustment for the use of fluid alcohol. The adjustment of the shelf at the upper mark 20 is such-that when fluid alcohol is placed in the upper reservoir 3, and this placed upon the lower feedin tank, the alco- 11:01 burns with a clear blue ame of intense eat.

The only change from the use of the stove as a kerosene oil blue flame stove to a liquid alcohol blue flame burning stove, is the new adjustment, above indicated, to the upper mark 20, and the removal of the usual asbestos wicks or-kindlers indicated in Fig. 6 by the zig-zag circle and in section in Fig. 7 and the chimneys 6; no admixture of air through the combustion tube being needed when alcohol is used because the adjustment of the u per mark 20 provides a perfectly burning ue flame when cooking vessels of any kind are used over the flame on top of the grates. If the burners be set substantially lower, the resulting flame, if alcohol be used, is not a proper flame; in fact it is a Streakyl white or yellow flame, and does not give t e heat of a blueflame because the proper line of adjustment is lacking.

The means for turning ofl' and on the liquid alcohol is the same as in the case of kerosene. When the tank is moved up to the new or upper adjustment, the protecting shield or bracket 15 attached to the lower tank, of course moves with it and appears above the top of the stove, where it serves to shield the, flame and also to protect the tank from the flame.

A second set of holes for the bolt 16 is provided to secure the new adjustment of the tank, the bolts passing through the same holes the member 17 but through diflerent which the can may be sli should, of course, be

cated in Fig. 2. It will be noted that the shield or bracket is provided with an offset or step at 21, to enable the bracket or shield to accommodate itself to the overlapping top, as seen in Fig. 3.

The so-called solid alcohol put out by many different manufacturers, is canned in receptacles or cans of practically the same diameter and height. When I use these cans of solid alcohol the fuel tanks may or may not be removed. In changing the stove or fuel shelf for use with solid alcohol, the said shelf 1s moved to the intermediate adjustment 20 and set there; but, of course, it may be moved to any other intermediate point that may seem best to suit the height of the partlcular can used. The center cap pieces 22 of the burners are removed from the tops of the burner cups. This leaves a cavity or hole in the center of each burner into ed, and in which it fits or rests with The can reaches its rests upon the Y-sha 23 of the burner cups, and I have indicated in Fig. 7, by dotted lines, such a can 24. s

I have also by dotted lines 25, in Fig. 4,'th e posltion approximately of the shelf when sohd alcohol is burned, the same condiroper seat when it cient adaptation.

- fuel supplying tubes tion is indicated in Fig. 2. The .V-sh'aped or diver ent tubes 23 furnish a secure base cans too large in diameter to go through the opening in the burner should be used, the shelf set lower by re-seating the adjustmg bolts in a manner that is obvious.

D1fl'e rently solidified alcohols burn with diiferent flames, depending upon the nature, or quantity of the agents used in solidification. Some give higher flames than do others, and the roper adjustment e accordingly. A can of s011d1fied alcohol also, when partially used, not glve as good a flame as at the beginning, and adjustment should be made for this. I may provide holes in the flange at the top for bolts 16.

My stove is also adaptable for use with the cubed alcohol, that is, alcohol solidified but not 1n cans, these cubes being purchasable almost anywhere. The cubes are placed directly on top of the center of the cap piece kerosene,

the or dirt and then applying a w ood fire beneath the stove. This does not mjure the stove for any of the other uses.

.It wilhthus be seen that I have devised a-* stove which is generally adaptable to use with fuels'of various kinds, and which can be readily and quickly adjusted to the use of the particular fuel employed by the V: greenest tyro without danger or possibility of. going wrong, the adjustments for the fuels sup lied in bulk, namely, alcohol and being substantially fixed. at definite points, and the adjustment for canned alcohol and cubed alcohol being left available at will, as also may be said of the use of the stove for wood.

In addition to the features pointed out herein it should be noted that the stove 1s made readily detachable by the .use of bolts 25, so that it may be knocked down if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: b
