WITNESSES L :NVENTOR MEM 5 I ATTORNEY brackets or standards 3. Secured to the bottom member v13 within the confines of each reinforcing late 14 is a slide 16, best shown inI Fig. 4, this slide comprising a piece of sheet metal bent 'mto appropriate shape to form a li 17 parallel wlth that portion of the slide esigned to be secured to the under inforcing plate' 14 and bottom 13 to secure the slide 16l in place, the bent 'over extension 18 thenuoccupying a position remote from the front of the oven structure, and the portion of the slide 16 extending toward the front lof the oven structure being open. These slides 16 are located near 'the' two ends of the bottom 13 within the space detoward the center of the oven.

The lips 17 are designed to support a gas stove made up ofa frame 21 carryin an appropriate number of burners 22, an the frame 21 is provided with legs 23. .The burners 22 are fed from a common supply pipe 24 from which are branched oi'A other pipes 25 to the burners, and each of these branched pipes includes al valve 26. One end of the supply pipe 24 is closed by a ca 27 while the other end is provided with a Ihose receiving nipple 28, the burner'structure being similar to the low type' of` gas stoves with multiple burners, there being .three burners in the showing of the drawings.

' The ends of the frame 21 are formed withV overhanging flanges 29 adapted to the lips 17, so that the stove 21may be pushed into position beneath the oven and su ported in closefrelation thereto by the lips IE7 then underriding the iianges 29, flames of gas is- :are cut out as lndicated at 46 into general lsuing from the burners 22, or any number of them, then impinging against the under side of the bottom 13 to heat the oven and the contents thereof.

By supporting the stove frame 21 on slides fast to the under side of the oven structure, this stove is normally stored out of the way when' it'is desired to use the stove 1, but may be readily removed from the slides and placed upon the top of the stove 1 or may be carried to any other convenient point of'utilization and there employed as an independent gas stove, the in` sertion and removal of the gas stovev 21 into or out of operative relation to the oven being readilyv accomplished without the neccssity of the use of any tools whatsoever. The bottom 13 at the rear central portion thereof in the showing of the drawings -is provided with an opening therethrough surroundedby a flange 30,-while the top of the casing 4 is provided with an opening sur- .in linewiththe led ings are in line with each other and are dc-' signed for the passage of the smoke fiue 2 of the stove 1. Fast to the bottom 13 at the lower portion thereof is a bracket 32 and this bracket carries a channel strip 33 having at one end outturned portions 34. The bracket 32 is wider than the channel strip 33 so as to provide ledges 35 on opposite sides of the channel strip 33, and the outturned ends 34 of the channel strip 33 are ges 35. Near the end walls of the casing 4the bottom member 13 carries on its upper surface brackets 36, each` having one upturned side 37 with one end of the latter inturned as shown at 38. The brackets 32 and 36 are of the same height and their upper surfaces form ledges or sup# ports of a height approximately that of 'the lower flanges of the openings'through 4the frame'5. Y fined by the Standards 3, the lips 1 7. facing In the oven casing there are-lodged the linings of two oven chambers, each of a Sme to be inserted into the casing 4 or removed' therefrom through the appropriate openings in the frame 5. For .convenienceof descrip-A tion, one of'these oven chambers is designated by A and the other by B. Each oven compartment lining is formed of end walls 39,

40, respectivel joined by a sheet metal top top and .bottom members 41,l 42 are turned back on vthemselvesas indicated at 44, and f the top and bottommemb'ers are turned over the end members 39 and 40v as indicated at r 45, being there riveted or otherwise secured to the said end members. The top and bot-` -tom members are also turned over on the :back memberA 43 and are likewise there riveted. l f.

The top andbottom members at one corner with the smoke iue 2 passing conformity t e oven and this cutout portion through has a filling-in wall 47 of sheet metal. The 'end member 40 is suticiently shorter than the end member 39 to agree withthis cut away portion of the top and bottom members, so that the front edges of the members ofthe top in Fig. 1, and' on the inner .walls these end members are formed with suitably disposed lugs 48 properly spaced to form ledges for the reception of various types of division walls or other structures used in ovens for Jmember 41, a sheet metal bottom member 42, and a sheet metal back member 43. For I purposesof rigidity the front-edges of the may all be Vdifferent cooking purposes. For-instance,

the oven chamber A may have an adjustable shelf 49 -providedon its under surface with grids are readily adjustable to different heights within the respective ovens.

There may also be provided a pan -52 adapted to any set of ledges within the-'oven chamber B and grid 53, these several holding devices being adapted to different vcooking operations.

Fast to one end wall of the oven casing 4 is a bracket 54, a bolt 55 being provided for the purpose of securing the bracket to the casing 4, while interior to this casing the bolt passes through an angle strip 56 bearing against the inner wall of the corresponding end of the casingand serving to suitably stifl'on the casingwall, which is made of sheet metal, to hold 4the bracket 54 inplace. This bracket carries a pipe 55a'having at one end a cap 56a and at the other end an elbow l57 by which latter the pipe maybe connect-ed to a suitable source of gas supply,

'the connections being omitted in the drawings as unnecessary for an understanding of the invention. Branched oft from the pipe 55a at appropriate points are other pipes each provided with a valve 58, and an air inlet member 59, 60, respectively, such as are commonly employed in gas stoves, and these two air inlets 59 and 60 are located exterior vto the casing opposite appropriate openings through the corresponding end wall of the casing.

In the end wall 39 of the chamber B near the top thereof there is formed a passage 61 for a gas conduit 62 projecting from a broiler v63 carried in the compartment B near the upper portion thereof, the conduit 62 having its free end shaped to form a practically gas tight connection with the air inlet structure 59.' At the other end of the broiler burner 63 there is provided a lug 64 having a slotted angle extension 65 throughwhich is passed a screw 66 enteringv a thread-- ed opening in4 an appropriate part of the end wall 40 of the chamberfB. The screw 66 serves to support the corresponding endof the burner 63,.the other end being supported by theconduit 62 passing through the 'opening 61 in the wall 39. By this means gas flames from the burner 63 may be directed downward into operative' relation to any material carried by the grid 51 or by the grid 53 inthe pan 52, whereby meats of various kinds may be broiled.

The top member 41 of each oven compartment A and B is formed with perforations 67 and the bottom member 42 .of the compartment B; may be formed with perforathis pan may contain a removable tions 68, these latter perforations being preferably close to the front of the oven compartmentwhile the perforations 67 may be distributed over the top-41.

In the bottom member 42 of" the oven compartment A is a central opening 69 through which projects the active portion of,"4

a burner 7 Olwhich may be of a size to practically fill the opening 69. This burner, which may be termed the-baking burner, is

fed by a pipe 71 extending from the burner under the bracket 32, thence beneath the compartment B and under the bracket 36 at the corresponding end of the casing,` and finally entering the air inlet device 60. The burner 70 is provided with a lug 72 on the side remote from the pipe 71 and a screw 73 passing through the bottom 42 and entering a threaded opening in the lug 72 serves to hold the oven compartment A and the burner 70 together. The compartment A may also be provided with a shelf 74 of a size to conveniently cover the burner 70 and this shelf is provided with legs 75 elevating it above the burner, these legs when the shelf 74 is in use resting on the bottom member 42.

When the oven compartments A and B are in place, the bottom members 42 rest upon the topsof the brackets 32 and 36 and are moved into engagement with the ends 34 and 38, respectively, constituting stop members. The oven compartments are therefore positioned with respect to the casing 4, so as to leave spaces 76 on all sides of these oven compartments except at the front where they n eet the flanges 7 of the frame 5, these front portions being closed by the doors 10 when desired.

The top member of the casing 4 is formed with a central passage 77 to which is secured a' flange 78 to receive a suitable flue and this iiange ,has upstanding perforatedears 79, by means of which a smoke flue encircling the flange 78 may be secured thereto. Between the standards or supports 3 and between the top of the stove 1 andthe bottom of the oven casing there is provided a backing sheet 80 which may be formed of sheet metal and may be made fast to the structures in any suitable manner.

The oven structure provides means Whereby different cooking operations may be performed,' because of the presence of the burners 63 and 70, or the general cooking operations due to the general heating of the oven may be'brought about by the use of the burners 22, these burners heating the air within the passages 7 G so that the compartments A and B are then practically enveloped in hot air.

As before pointed out, the stove fra-me 21 is readily removed bodily from the oven structure for use `elsewhere if so desired, but when not in use or when in use in connection .with .the oven structurethis stove frame 21 is supported by the lips 1,7 in proper rela-` tion to the stove structure. When either or both of 'the burner-63 and 70 are to be used, gas is supplied lthereto by the pipe 55 through the valves 58.

When it is desired to remove the oven compartments A and B or either of them i it is only frictionally. connected to the air supply means 59, and then both ovencompartments A and B may be pulled out from the interior of the casing 4 through the respective openings in the frame 5, the front vedges of the top. and bottom members 4l and 42 yielding readily to a moderate force applied thereto if itbe necessary to bend these members at all inorder to` remove the oven comv partments from the casing. After repairs have been made, if necessary, and the cleaning of the interior of the casing 4 has been completed, the oven compartments A and B are readily replaced by being inserted through the openings in the frame 5, sliding on the brackets 32 and 36 until stopped by the members 34 and 38, respectively.

Now, the screw? 3 is reinserted through-the bottom 42 and into the lug 72 of the burner 70, thus fastening the oven chamber A in place. The burner 63 may now be replaced by having its conduit 62 passed through the passage 6l in the wall 39 of the oven com- "partment B and into the air inlet member 59 and the screw 66 may-then be passed through the lug 65 and into the end member 40 of the compartment, thus fastening the compartment in place. The removability of the oven chambers greatly facilitates and economizes repairs of these parts, since the walls of the oven compartments are the parts subject to the greatest wear and require repairs sooner than other parts. Such repairs may be made without in any manner ldisturbing the main st-ructure. The

oven compartments being so readily removable it is an' easy matter to thoroughly.

cleanse the oven structure at frequent intervals, so that sanitary conditions may be readily maintained.

The passageof the smoke pipe of the stove directly upward through the gas range between the oven compartments simply causes the cutting of of al small portion of a nonusable corner of each oven' cmpart-ment so that the'eHective size of the oven is not reduced. ByI connecting the supports .or standards to the under side of the oven casing one size combination oven and gas stove may be used on any domestic size of coal range by simply shifting the brackets to suit Athe coal range.
