(o1. m -as)- My present invention relates to improvements in stoves of the liquid fuel type and designed as a 2 folding-kit, cooking stove, composed of one, or of a plurality of units, and in whichthe units may 1 5 leecompactly; arrangedto' insure comfort and convenience in the transportationoftheportable kitI- -Means are provided whereby the equipmentmay with facility be set up for use'and thefparts of; thesto've are so combined andarranged as to provide an* efficient, --economical, and durable stoveof this type. i i

-In carrying out my inventionl have combined and arranged various parts of the portable,- folding kit'stove in such manner as willihereinafter companying' drawings I have illustrated one complete example of the physical-embodiment of my invention wherein a the parts are combined unit the stove. t t Figure 6 is a perspective "view showing two units folded together, and Figure 7 shows four units coupled together for use. Q

In order that the general "airrangementfiutility, andr'elationofparts may readily be understood I have shown in Figure 71 fourof the'stove units as A, B, C, D, coupled together and ready foruse, while in Figure 6, two of the, hinged units are shown folded together, theuriitsAand B forming a folding-kit. Thus, the two units'A and B may be hinged together at 1 as a permanently coupled, and foldable unit, while the separable units C and D may have detachable unit- hinges 2, 2, that may be coupled to the base unit A- -B.

It will thus be apparent that one unit of the stove may be employed as a single unit A; a pair of units as A and B may be employed; or the multiple stove may be made up of a number of separable units, as C and D added to the base pair.

The construction of the separable hinges 2, 2, is illustrated in Figures 4 and 5, where the bracket 3 and its rigid pin 4 are riveted or bolted to one unit of the stove, and the hingeplate 5 7-7 and 88, the firstunit A being provided bemore fully set forth and claimed; In the acpairs of folding legs.

and arranged according to the best mode I have thusfar devised for the practical application'of lower right corner of Figure 6.

of the hinge joints between adjoiningunitsof with its hinge-hooks 6, 6, is riveted tolan adjoining unit. Thus one unitgas C, willhave one member: of the hinge as 5--6 -(in pairs) at one side, and another" member 3 -4 (inpairs) at its other side in order that the separable units may 5 be coupled together as required. Usually a pair of the units are coupled together, as in Figure 6, for compact arrangementin storing or shipping. The unitsare provided with foldable legs as with two pairs of "legs, and the remaining hinged unitsbeing each provided with'one pair of folding legs,'and the complementary hinge members just described. The multiplestove of Figure 7 is thus supported by the hinge joints and'the Each leg is fashioned with a hole 9 and a brace 10 joins the legs in pairs, said bracehaving bent or hooked ends 11 that fitinto the holes 9 when the legs are extended, as in Figure 1, to brace the legs, *andthis'brace bar 10 is removable when the legs are folded to compact position, as in the At their, upper ends the legs are turned over to form hinge sleeves 12 that fit around the round 5 rod 13 which is mounted in the body of thestove unit 14 and retained, as a reinforcing orstrengtheningmember, in the turned-in edge 14' or bead that is fashioned around the bottom edge ofqthe a stove body 14. L 30 As indicated in the drawings, the body of the stove is an open, rectangular frame upon which the folding legs and the hinge joints are mount ed, andthe upper part of this bodyeframe is fashioned with a top flange 15 having anopen,

circular, central portion in which the burner por tion of the stove is located. I g

The burner portion includes a stepped ring having an annular top fla nge 16 by "means of which the burner-ringis attachedv to the stove bodyand the body of'the burner ring is located within the open stove frame 14. Below the horizontal attaching flange 16 the burner ring is fashioned with a circular wall 17 which merges into a horizontal flange or shelf 18, and below this shelf or ledge 18 a circular wall 18' merges into the flat, horizontal, open-center, bottom 19. The bottom, the two circular walls, and the ledge, as indicated, are provided with vent holes 20 through which air may pass from the exterior of the burner ring to the interior thereof for the purpose of supporting combustion.

The open-center bottom 19, as best indicated in Figures'2 and 6 isfashioned wi h n annular- 55 flange 21 depending therefrom, and this flange is fashioned with a spiral thread 21a for co-action with a complementary groove 22a in the burner 22. This burner is an alcohol burner of standard or well known type as here shown, but it will be understood that any other suitable type of burner may be used. At the left in Figure 2 the burner is located in position for use, and at the right in the same figure, the burner is shown as elevated within the burner ring in order that only a minimum portion of the burner twill .project when the two unitsare folded together, that is, when the stove is not in use, but is ready for storing or shipping. By means of the threaded v connection between the burner and the flange 21, the position of the burner may be adjusted with relation to the utensil that is supported on the stove unit in order to vary the intensity'of the flame in its impingement on the bottom of the cooking utensil.

' Means'are also provided'for'cutting off, entirely, the flame of the burner from the utensil, and for partially cutting off direct contact of the flame with the bottom of the utensil, andfor this purpose I'employ a pair of rectangular slide plates 23 and 24, located above the topof the burner: and adapted to cover, or topartially cover, the-burner. These plates are slidable with relation to each other toward and from the center of the burner, in complementary slots 25 of the circular wall-18', and the lateral edges of these plates slideuncler retaining flanges 26, which are arranged in parallelism at opposite sides of the burner. At their outer ends the slide plates are provided with downwardly bent flanges 27 which are used as handles in adjusting the position of these plates.

It will be'apparent that the larger sizes of utensils may be supported above the burner, directlyon the top 15 of the stove unit, but for smaller utensils I employ an adjustable and removable grid that is supported in the burner ring.

This grid comprisesa number of grid arms 28, here shown as 4, each of which is pivoted or hinged on a vertical axis or pin 29 of a bracket 30 and the-latter isriveted or'otherwise secured to the ledge 18 of the burner ring. As indicated in Figure 1- the bracketsare located at diametrically -opposite points about center of the burner and the arms maybe swung, in pairs, in diametricalarrangement, or they maybe swung to positions where they are tangentially disposed about the center of the burner. In eitherposition they are adapted'to support a utensil over the flame from the burner, or if not required for use, these arms'may beswung from position over the'burner to positions over the ledge 18 where they are inactive.

'While'I have illustrated and described a preferred formand physical embodiment of myinvention, it will be apparent'that changes and alterations may be made in the construction, within the scope of my claims and without departing from the principles of my invention.

This form of the invention is especially well adapted for camping equipment and for out-ofdoors use generally, as well as for use in water craft and air craft, and in apartment houses or other places where the space is restricted. The invention provides an economical and smokeless equipment that is free from-fireghazards and which may with facility hepacked in; storing or shipping, and with equal facility the equipment may be assembled or set up for use, and provide an eflicient means for use in the preparation of meals, at comparatively low cost and with a mini- ,mum of labor.

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

1."In a multiple unit stove, the combination with abase unit having foldable' supports, of a second unit permanently hinged .at one side to said base-unit, a foldablesupport for the free side of the second unit, said second unit ,having a separable hinge member at its free side a third unit havinga complementary hinge member for the separable hinge member, and a foldable supporttforr the'free. side ofithe third unit. r
