mately along the line 99 Fig. 1 and illustrating the manner of mounting the inner end of the fluid fuel supply pipe upon the inner face of the solid fuel burner unit.

In the illustrated embodiment of the invention, the base 1 is provided with the usual supporting legs 2. An upright structure 3 is mounted upon said base at one end thereof, and a solid fuel burner unit is mounted upon said base at the other end thereof. both the upright structure and unit extending entirely from front to rear of said base. The upright structure 3 is provided in its upper part with an oven 5 of any suitable construction having the usual door 6 in the front thereof, through which access may be had to the baking chamber of the oven, the door in this example being hinged along its lower edge so as to swing forwardly and downwardly when opened. The hinge may be formed for example by passing a rod 7 (see Fig. 8) through the lower part of the door 6 and at both ends through a shouldered wall 8 forming the inner wall of the baking chamber. A suitable cotter pin 9 or the like may be passedthrough the rod 7 in the port-ion projecting through the wall 8 to lock the rod against withdrawal.

The solid fuel burner unit at may have the usual fire door 10 enabling the addition of fuel as required, and the usual ash pit door,

11 and the shaker device 12. The fuel door 10 may be hinged along its forward edge so as to tip forwardly and downwardly when opened. A smoke flue bracket 13 is provided upon the; rear face of the solid fuel burner unit, said bracket having a. sleeve portion 14. over which a .smoke pipe or conduit 15 may be fitted. The bracket part 13 may have incorporated therein a suitable damper 16 by which communication of the unit and flue pipe 15 may be largely established or broken.

The heat passing upwardly through the bottom wall of the oven portion of the up right structure, passes upwardly through the baking chamber and through apertures 17 in the inner top wall 8 thereof, and into the space between the two top walls, thence rearwardly through the top, then through apertures 18 into the space 19 between the two spaced rear walls of the upright structure.

A split elbow is secured to the upright structure upon the rear face of the lower part of the oven portion, and communlcates with the oven space 19 through an LVLMLtElLB 21. A deflector plate 22, preferably V- shapcd, may be provided in the space 19 above the aperture 21 so as to deflect the hot gases passing downwardly in the space 19 lo sides thereof before admitting it to the aperture 21.

lhe split elbow 20 is connected by a flue pipe or conduit 23 (see Figs. 1 and with tl smoke conduit 15 that extends upwardly from the solid fuel unit. T he smoke conduit 15 is provided with a circular connector boss 2%. upon one side, and with an aperture in the portion covered by the boss, the flue of conduit 23 beinp in telescopic relation with said. boss whereby the interior of the flue or conduit 23 will be in communication through the boss 2 f with the moke conduit 15. The smoke conduit 15 will, of course be connected to a chimney or the like. The flue or conduit 23 is provided with a plurality of small apertures 23 (Fig. 6) disprsed along its bottom wall and of an aggregate area at least equally that of the conduit 15, whereby any draft created in the flue 23 by the gases in the conduit 15, will not exhaust heat from the oven 5, but will merely draw in a volume of air through the apertures This will not interf re with the passage of the hot from the oven 5 along the top of the conduit 23.

ii stove top 25 llflving burner openings 26 thcretln'oul h is connecte between the top of said unit and the side wall of the upright structure, and at a it 'r-l suhst ally that of the surface of the unit. A bracket 27 is secured upon the to) of the unit, at its outer side edge, in d a back all 528 is connected between the LP structure at one end and bracket 2? and the unit at the other end, rid back wall extending downwardly to the base and as high as the upper face of the upright structure 3. A shelf 29 may be connected to the upper end of the bracket 27 and to the upper end of a side wall of the upright structure so as tov form a substantial continuation the upper face ofthe upright structure. A warming; hood 30 may be.con nectcd to the upright structure, the shelf 29, and the bracket 27, such warming hood havin a rear wall 31 which extends upwardly from the back of the range and then for-- wardly over the shelf 29.

A container 32 for a source of liquid fuel is mounted by brackets 33 upon the outer side faces of the upright structure, and a pipe 84 extends from the lower part of said container down *ardly to a slight extent and then through the upright structure and above the base to a point adjacent the solid fuel unit 4t. The end of the pipe adjacent the unit 4: is closed by a cap 35 (Fig. 9)

which is received within an opening of a boss.

tilting arms which radiate therefrom and conduct the fuel to burner wells provided in the casing 421, the latter having suitable burner mechanism therein. Rack bars 4:) depend from the radiating arms flO and are slidably received between the arms 4:3 of two telescopically arranged channel strips 44, which channel strips embrace and are securely clamped to the upstanding branch pipes 38.

21+. shaft extends transversely through arms of each pair of telescopic channel :5 and in front of the racks. Pinion segwe fixed on said shaft in the planes bars and between the arms l3 lescopic channels. When the shaft s ed the rack bars will bc'elevated owere'l and, therefore, the pipe '39 will l c lowered into or extended from the branch pipe 38, tlrus elevating or lowering the fuel well in the casing l1. The receptacle 32 is tue constant level type the inverted bottle ll thereof discharging into the bottom of the receptacle automatically to maintain a constant level therein in a manner well known. Thus as the casing 41 is elevated or lowered, the effective oil level therein will vary, and as well known ii he art the intensity of the i'ldlllc from the is nor will vary.

A separate burner is provided for each branch pipe 38, one burner being provided the oven and. within the upright structure, and one or more (two being shown) beneatl'i the stove top and in the space between the upright structure 3 and the solid fuel burner unit 4. of the upright structure are provided with vertically elongated apertures 48, through which the pipe with its branches 38 may be inserted, the pipe being confined to the upper end of each slot by plates 49 which are secured in any suitable manner-,such as by screws or bolts. to both faces of each side wall of it ie upright structure.

may have notches in "their upper ends which engage beneath the pipe 34; and hold it securely against vibration.

A plate or bar 50 is disposed across the front of the lower part of the upright structure and secured to the side walls thereof. The plate 50 is mounted at approximately the height of the shaft 45 which controls the ty of the burner in the upright structoe, and the shaft l5 passes through and has bearing in the-plate 50. The outer projecting' end of the shaft 45 is bent angularly to form an operating crank arm 51,

All

s aller pipes 39 are telescopically mounted a Z )aclted by suitable stuffing devices (not 51 i). The smaller pipes 39 carry fuel The side walls Such plates Qil and this'crank arm cooperates with suitable character designations 52 and 53 representlightcd and out positions of the burner, so that one may know from the position of the era l: arm 51 the condition of the burner. l

A similar plate 54 is mounted between the solid fuel burner unit l and the upright structure, and the shafts of the other burners beneath the stove top 25 extend through and have bearing in this plate. This plate also carries the designations 52 and 53 which cooperate with the cranl: arm of the shaft lfi to indicate the condition o each burner. A heat shield 55 may be mounted upon the outer side face of the upl'l,.- llt structure to protect the fuel source. in

bottle 47 and casing 32 from the heat of the the oven and the burner in the upright struc ture. Pans 56 and 57 may be mounted upon the b below the bin ers to catch any drip .Ll om the burners or from cooking utensils which may be boiling over. The pans may be removable to facilitate cleaning of the same. c

In order to eliminate the number of burners which are necessary for cooking purposes and in order to economize in the consumption of liquid fuel, the single burner may be utilized for two cookin burners or rate apertures 26. The burners are disposed well toward the forward face of the range, and directly above each burner is a grate opening 26 having a grate 58. Immediately in the rear and spaced therefrom is asecond burner opening 26 having another grate 59 therein, the grate 59 having its ribs prefcrably extending above the grate opening so that when an object is resting thereon the hot cooking gas may pass upwardly thrmigh the grate and along between'the ribs and then out from under the object or utensil resting thereon.

A heat distributing shell 60 is mounted beneath each pair of burner or grate openings 26, and with the stove top forms a chamber which connects with the two grate openings. This shell 60 has an aperture 61 therein directly over the burner so that the heat from the burner may pass upwardly into the chamber formed by the shell 60 and through the grate openings 26. If a vessel or objcc' is resting upon the grate opening directly over the burner it will be heated, and the excess hot gases instead of passing upwardly around the vessel and being lost, will pass through the chamber formed by the casing 60 and up through the other grate opening 26 to supply heat to an object resting thereon also. These two burner or grate openings are thus supplied wit-l1 heat from a single source.

The even may have suspended above both burner or grate openings thereof a heat deflector 62 which is concave from side to side and inclined u iiwardly toward the rear, to cause a considerable portion of the heat from the forward burner which passes upwardly through the forward grate opening in the bottom of the oven, to l'e deflected rcarwardly and spread laterally by the heat deflector Thus all parts of the baking chamber of the oven Will be uniformly heated.

l lith a construction such as above described and illustrated, it will be obvious that by utilizing the same parts, either a right hand or left hand range may be pro duced, merely by the assembly operation. In Fig. 1, this alternate feature is illustrated, the dot and dash positions illustrating the placing of the oven and coal burner parts '92 l. H1 "nv at CllllOlOIlb ends. nus in mg. 1, the full lines indicate the appearance of a range of the right hand type constructed in accord ance with this invention, and-the dot and dash lines indicate the changes in the assembl y of a range when a left hand type of range desired. \Vhen the range is of the left hand type, the unit l will be at the left hand end of the base, the upright structure at the right end and the other burners and burner top will be interposed between them as in this illustrated embodiment.

The smoke conduit 15 may be reversed through 180 upon the bracket 13, so that it will afford a direct connection for the oven flue 23 when the oven and unit 4: are placed at the ends of the base opposite from that shown in Fig. 1. The range is made practically entirely from sheet metal and fabricated parts which may be assembled as explained for either av right hand or left hand even, so that practically no; greater number of parts are required for the manufacture of both types of ranges. Such a ran e may be easily and readily assembled, and when so assembled will provide a very practical and effective range, and one which is convenient and att-active in appearance. The solid fuel burner and the fluid fuel burners may be used selectively or at the same time. 7

It will be obvious that various changes in the details, which have been herein described and illustrated for the purpose of explaining the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
