(01. 126-65) This invention relates'to stoves,'and with regard to certain more specific features, toportable stoves, 'particularly for burning coal and wood and for'domestic or camp use.

Among the several objects of the invention may be noted the provision of a light, sheet-metal .stove' which may be manufactured: by methods .known to the sheet-metal stove industryythe provision ofa'stove of this class which may be readily knocked down and nested for shipment .in compact packages; the provision'of a stove of this class which shallhave-an improved form of. combustion chamber and draft arrangement; andthe provision of a stove of thisclass which 15.:shal1 have'a pleasing an'dmodern appearance. Other objects will be in part obvious and in part pointed out hereinafter.

The invention-accordingly comprises the-elements and combinations of elements, features of constructiongand arrangements of'parts which --willxbe exemplified in the structures hereinafter :dBscribed, and the scope of the application of which'will be indicated inthe following claims. vIn theaccompanying drawings, in which is illustrated one-of various possible embodiments of .the'inventio'n, r

.-Heretofore' sheet iron stoves'have been made informs 'whichnot only have an ill-appearance butwhich'are fdifficult toship because they can '55 IlOtibHkIIOCkGd down'and'nested so as to'iorm a manageable packagefor any substantialnumber of stoves. They have furthermore'had forms not welladapted to burning wood, such as circular; elliptical and like forms. This hasbeen particularly true of wood burning stoves for in- 5 door use.

Referring now more. particularly to Fig. 1, there is shown at numeral I a bodyportion of the stove comprising a U-shaped sheet'3 forming the sides 5 and top I. The sides Sand top I are provided with indentations 9 for strengthening the otherwise plane surfaces. While these indentations are shown as ridges in the present embodiment, it is to be understood that theymay be made according to other forms. I

Rolled to the U-shaped piece 3 are end pieces II and I3 which, with the U-shaped piece 3, form 7 a hollow'frusto-pyramid, having an open bottom. It is to beunderstood that instead of using a roll fastening,-bolts and nuts, tongues and slots and/or retaining bands may be used'for. joining the parts 3, II andl3. g p I In Fig. 8 isshown the bottom I5 of the stove which comprises a fiat-sheet having narrow frusto-pyramidal sides I! at the base of which is outwardly rolled a bottom bead I9. This bottom telescopes through the lower opening ofthe stoveso that the said rectangular opening seats behind the bead I9 (Fig. 1). If coal is to be used a grate is used on the bottom and a suitable ash door is placed in the bottom'of the front member 5.

Holes 2I provide for fastening the bottom I 5 to the frusto-pyramid. Corresponding flioles are placed at the corners of the body I, and also corresponding holes in supporting legs '23, so that single bolts hold the respective legs 23 and. bottom I5. Corresponding holes in the legs 23 serve to .permit application of bolts 25 for preventing rotation of said legs 23. The legs may be cast, forged or stamped.

It will be seen that the bottom edge of the body I is recessed behind the rolled bead I 9 so that said bead I9 onthe bottom I5 forms a trim for the bottom of the body I. The positioning of the bead I9 outside of the lower edge of the frusto-pyramidal body I insures rigidity after the. stove is assembled, because it tends to maintain the'lower rectangular openingof the body iinproper form and. prevents any incipient separation at the rolled seams between parts 5, l I and I3.

The'rearward wall II of the bodyportion I is provided with a smoke pipe 21 having a removable connection 29 ..so that the .smoke ,pipemay: be

taken off and/or rotated before reapplication, as indicated by the dotted lines.

The front wall I3 is formed with an indentation 3I having a bottom ledge 32 and providing a substantially vertical wall 33 having an indentation 34 for supporting a firing door 35.

The firing door 35, as shown at Fig. 5, is of special construction and consists of a bulged sheet 31 having a rolled edge 39 and an adjustable draft control 4|. Interiorly, a baffle 43 is spot welded about the edges of the bulge 31 but leaving an opening 45 at the bottom of the bulge, so that air entering the draft control M is forced downwardly, to be preheated as it flows over the baflie 43, and entering the stove at the opening 45 in a preheated condition. Rolled edges 41 on the opening which the door covers cooperate with rolled door edges 39 to improve the seal of the door 31 with respect to the surface 33.

The door 31 is mounted on hinge elements such as shown in Fig. 4. Each hinge element is fastened inside to the depressed portions 34 by means of a rivet hole 36 and comprises a hook portion 49 which is adapted to pass through a corresponding opening 5I within the rolled edge 39 of the door (see Fig. 6) By applying the hook 49 through the openings 5I and causing it to pass round the head 39, the door may be hinged at as many places as may be desired. In the present example, two hinges are used. A suitable latch 53 is used for holding the door shut.

In order to obtain primary air below the fire, the ledge 32 is provided with a plurality of openings 55 (see Figs. 1, '7 and 9) adapted to register with a corresponding plurality of openings 51 in a sliding register piece 59. The register piece 59 is held to the face of the ledge 3| by a fastener BI slidable in a slot 63. The degree of sliding movement of the register piece 59 and the recess 3| is such as to bring the openings 51 and 55 into or out of register. A finger piece 65 is turned up to function as a control.

The rear and front members I I and I3 are beaded to the U-shaped central member I during manufacture and these three pieces form a permanent frusto-pyramid which may readily be nested with other like frusto-pyramids from other stoves of like or different size, thus making a compact nestible arrangement for shipment. At the same time the frusto-pyramidal bottoms I5 may be stacked and laid with the stacked frustopyramids (see Fig. 9). The small number of miscellaneous parts such as the legs 23, pipes 21 and doors 35 may be removed and carried inside the frusto-pyramids.

Thus a plurality of stoves, when knocked down for shipping, take up little space. All of the body parts being made of sheet iron, the stove is light. The gauge of the sheet iron is, however, substantial so as to provide a substantially rigid structure.

The frusto-pyramid form of the stove has several advantages. This form provides a relatively large rectangular bottom upon which logs or sticks of wood may lie in such a way that a maximum amount of wood may be placed in the stove at one time. No wood members need to lie at diagonals against the sides of the stove, as is necessary in the old elliptical and circular forms of wood burning stove. The spreading nature of the downward regions of the interior assure ample space in which lies this wood, and the tapering features of the upper regions insure that there will be no useless dead air pockets in the draft circulating systems. At the same time, the radiating surfaces 5 are directed upwardly so as to provide the emission of heat in the direction most desired. Also, the flat top 1 may be used for supporting vessels to be heated without interference from firing holes or smoke pipe attachments.

The rectangular firing door in the recess 3| provides not only ample room for placing wood but for inserting a shovel for the removal of ashes. The old type of wood stove having an opening in the top was not easily cleaned, whereas this stove is.

In Figs. 10 to 12 is shown another form of the invention in which the frusto-pyramidal form is used but the central U-shaped portion 1 is so articulated to the end members I I and I3 so that these parts are separable for shipping purposes. This is accomplished by telescoping the end members II and I3 over the end portions of the U- shaped member 1 and providing bolt holes through which bolts 2 may be passed. The bolts 2 also hold in position nickle-plated or like decorative beading 4.

Furthermore, in this embodiment of the invention the legs 23 are pressed integrally with the end members I I and I3 so that one shell is eifective to form the stove and the legs thereof. In this case, the telescoping bottom I5 is provided with the same type of bead I9, except that the bead is relieved at points which are necessary for positioning of the legs 23, as shown in Fig. 10. It will also be noted from Fig. 11 that the bottom I5 is illustrated at B as being corrugated for purposes of stiffening the same. This corrugation may also be applied to the form of bottom shown in Fig. 8.

Another feature of the alternative form of the invention is that, instead of placing the smoke pipe connection on the rear end II, it is placed in the top of the stove and in the U-shap'd mem- 40 her 1. This is accomplished by cutting an opening and forming a receiving bead 8 for the pipe nipple III. This procedure reduces the top area of the stove but still the flat area at this region is greater than that employed on previous wood stoves where the firing door was also on the top. It will be understood that although the smoke pipe connection in Figs. 10 to 12, is shown as being round, that it may also be elliptical if desired, and that in the latter case, it may also be placed at or near the curved topportion of the back member II.

Another feature in the alternative construction is that the door 35 is hinged at the bottom, as indicated by hinges I2. An adjustable draft inlet I4 is used below the door and an adjustable draft inlet IS on the door. A draft deflector 43 has also been shown in connection with the door in the form of the invention shown in Figs. 10 to 12.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
