AburnerlS-isprovided that may be of any suitable form and located or sup-2 f ported within the ovenin any suitable manner and supplied with fuel fronrthe :pipe 15 (F ig. 2) through a valve19, pipes 21 and 22, which may be connected directly or through athermostatic'oven control device, or likedevice for controlling'th e heat' ofthe oven through the fuel supplypnot shown on the drawings, ormay' be connected together if desired to conduct the fuel from the pipe 21; directly to the pipe 22. spray device or jet 23 is or maybe secured to an end of the pipe-22 and arrangedto project the'fuel into an arm 24 that is'arranged to conduct the fuel to the burner.18. and preferably to mix the fuel with air. or another fiuidduring its passage tothe burner 18. In the usual form provided to mix air with gas, as is the'common' practice in gas stoves. An end 26 of the arm 24 may be secured or attached to the burner 18 in any suitable manner such as by threading the end 26 into the burner substantially as shown. -When the burner 18 extendsnear one of th'e'doorsrl7, and when the door is held in closedpo'sition by means of a spring clip 27 of any form, itis desirable to protect the spring clip from the direct heat or radiated heat of the burner and to accomplish this a bracket 28, which may be of any suitable form and arranged to support theburner "at one or more points, is fastened to a frame part 29 of thestove by any suitable means, such as by a bolt 31 or the like, and over the spring clip '27. The bracket'28 is formed to provide a plurality of wwa-lls 32 that substantially embrace the clip or surround the inner or exposed side of the clip to shieldthe clip from the heat. These walls maybe continued to abut against the door aandformed to the contour of the frame part 29 to cooperate with the door to completely enclosethe spring clip 27 when the door 17 is in closed position.

An end 33 of thebracket 28 is preferably slotted as at 34 to receive a'pin 35,;which may be formed on or attached to an arm 36 of the burner 18 to locate the burner in fixed-position" within the oven. ;The burner 18 may be supported atone ormore other points in the oven'in any suitable manner where'a singlewalled oven is used, or where the oven is 1111611 with hannan that is permanently secured in place, and in the present instance I have,

shown a plurality of lining'sheets 37 posi tioned from the walls"1 6 'to providean air chamber 'or a space about. the enclosure or 7 I present instance I have shown an end 25 of the arm 24 of the oven and that may be formed in any suitable instance the sheets 37 shown at the left and right (Fig' 2), oron the left and right hand walls, areformed to pivot about the front wall for removal, after the bottom plates,

that are or. may besecured by bolts or the like,

are first removed,ll'l The rear end'of the sheets 37 may be alternately swung inward toward the opposite sheet, lifted away from the front corner and dropped through the bottom of lifted bodily forward and removed through the bottom also. A support bracket 38 is provided, for supporting the rear end of the burner 18, or'the end or side opposite the bracket 28, which bracket is preferably arranged to support." the burner at at least two spaced points, this" being accomplished through the lugs 39 formed integral with and to extend from the burner 18 to engage the support 38'. If the'support38 were bolted or otherwise permanently secured to the rear wall 16 or rear lining'wall 37, it would be impossible'to swing the plates 37 inwardly'far enough to drop'them through the bottom or to remove them and to permit the removal of thelining plates. The support bracket 38-is formed for interlocking demountable engagement in the rear wall 37 and so that, when the burner is removed,,itmay be re moved from the oven by merely lifting on the plate and withdrawing it from contact with the wall. This is accomplished by forming the support 38 of substantially L-shape to supporttheburner through the lugs 39,:side or winglugs 38bein gformedon'the bracket 38 and adapted to engage'the burner lugs 39 in orderto prevent lateral displacement of the burner. from operative position. One or more projections are formed on the support 38 and are ada'ptedffor interlocking engagement-with the p1ate'37. In the present instance I have shownthis' projection extendingthrougha slot 40 formedin'the wall 37 and comprising a ho'oked part 41 anda supporting parti42, the supporting part 42 preventing. downward movement of the support, 'andithe hookedpart 41 preventing'the for wardzmovementof the top of: the support and holding the part 42incontact with the sheet struction'an' opening 44o'f' any suitable form 'inthe wall sheet or plate '37. WA collar 45 is preferablyprovided that may be formedon or attached to the arm 24 in any suitable manner 3 of larger diametrical dimensions than the openings 43 and 44 for spacing the walls 16 and 37 apart, a portion 48 of smaller diametrical dimensions than the opening 43 and adapted to extend therethrough, and a similar portion 49 arranged to extend through the opening 44. A wall 51 is formed in the bushing 46 which is provided with an aperture or an opening 52 which may be of any suitable shape and of sufficient size to permit of projecting the end of the arm 24 therethrough and of slightly less size than the collar formed on the arm 24. A plurality of lugs 53 may be formed integral with the arm 24 or collar 45, or both, as shown, to engage o the wall of the opening 52 at a plurality of points for supporting the arm 24. The wall 51 in the bushing 46 is provided with one or more, or a plurality of substantially circular portions 54 of thin material, that is, the bushing is cast to provide thin wall portions of circular form or the like and in the present instance I have shown two such portions that may be removed by impact such as by driving out with a punch or other suitable tool to provide an opening and bearing for a fixture or a pipe 55 or like device forming a part of a pilot light fixture which in the present instance includes the pipe 55 and an extension 56 of pipe or tubing of any suitable diameter arranged to project fuel to the vicinity of burner openings 57 The bushing 46 may be pressed into the opening 43 in the sheet 16 when a singlewalled oven is used and may have aloose 5 seat in this opening and in the opening 44 when a double wall is used, since the portion 47 of the bushing is of larger diametrical dimensions than either of the openings and provides a spacing means for spacing the walls apart so that when the bushing is positioned in the opening 43 in the wall 16 and the lining wall 37 assembled to position the bushing is held between the walls and may have a bearing on either or both. The burner 18 may be lifted from its supports 28and 38,

and by a slight twisting motion of the burner to the right (Fig. 2) and rotation of the arm 24 the arm may be withdrawn through the opening 52 or inserted during assembly by a similar motion. The supports 28 and 38 are so arranged that when the burner 18 is in position thereon the collar 45 will be pressed against the wall 51 of the bushing 46 to prevent the escape of heat about the arm 24. The

bushingis arrangeable in or between either oven thermostatic device is used, the pilot light fixture being provided to re-ignite or insure the lgnition of the fuel at the burner after a period when the fuel has been entirely or substantially cut off by the thermostatic control and when the fuel is again turned on thereby.

It is thought that the invention and many 1 of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changesmay I be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim: 1
