In the accompanying drawings, which illustrate a preferred embodiment of the invention, a stove constructed in accordance with the present invention is indicated generally at I0. Included in this stove is a broiler` compartment indicated generally by the numeral I I, having a bottom wall I2, rear wall I3, top wall I4, and side walls I5 and I6, these walls preferably being double as shown with heat insulating material therebetween. Front Wall I1 hasan opening I8, which is of sufficient size to receive the broiler frame, indicated generally at 20, and associatedv parts. Closure I9 is provided to close opening I8, and is preferably rigidly attached to broiler frame 20, and

movable longitudinally therewith, these parts being so related that closure I9 closes the compartment when frame 20 is in itssoperative position:

2l is provided within the upper part of the broiler compartment. I

Broiler frame 20 provides a base on which the food supporting mechanism is mounted for cooperative relation, at various elevations, with respect to heat source 2|. In the embodiment shown, the frame 20 comprises a bottom plate 22 which is formed of sheet metal and provides a surface for collecting any food material that may fall during cooking. The sides of bottom plate 22 terminate in upturned flanges 23, which are preferably formed integrally with the bottom plate 22 and secured at the four corners as by spot welding. These flanges serve to form with bottom plate 22 a tray protecting other parts of the broiler from food particles, and also serve as atjtaching means for the closure and other associated parts. The rearwardly facing portion of flange 23 is provided with an upstanding reinforcing vplate 24, which extends across the entire width of the broiler chassis, and upwardly to a point somewhat belowthe level of the top of opening I8. Supported from this reinforcing plate 24 are side bearing plates yor brackets 25, which are located on either side of broiler chassis 20 and extend from the top of reinforcing plate 24 to bottom plate 22, where they are fastened. These bearing plates or brackets 25, are located somewhat inwardly of the side portions of flanges 23, to provide the necessary clearance space for the food supporting mechanism to be described below.

The broiler frame 20 and its associated parts is provided with means .for their withdrawal. In

the embodimentlshown, this is accomplished by the use of two pairs of rollers and a pair of track members. Forward rollers 30 are supported from bottom wall I2 of the broiler compartment by means of brackets 3|. These brackets. carry bearing pins 32 on which rollers 30 are mounted, and are located at the forward or open end of the broilercompartment, and so placed laterally as to underlie the edges of bottom plate 22 `of the broiler frame 20. Movable rollers 33 are mounted on the broiler frame sides, and at the rearward portion thereof, by means of stub shafts 34 fastened at the rearward portion of the sides of flange 23.v These rollers engage tracks 35 which are iixedly attached to the side wallsof the broiler compartment. It is also apparent that Athe rollers on the same side of the frame are displaced laterally, thusallowing the broiler frame to be completely withdrawn without the two sets of rollers Vinterfering each other. 'v'lracks from the pair of bearing plates in overhanging Y Broiler pan relationship to bottom plate V22.V support 40 comprises a rectangular frame portion, having VYrearward extensions 4I formed on the sides thereof. It is preferred to form this pan Vsupport from a U-shaped strip of lsheet metal, the sides of the U forming the side portions and the integral extensions 4H,VY the .side Y portions being joined by cross piece 42, which is preferably inturned at the ends and weldedto the side portions of support 40. The rearward ends of .extensions 4I carry inwardly facing. pins 43 which are received in curved slots 44 formed in each of the bearing brackets. 25V and thus provide for limiting longitudinal movement of the support while providing for adjusting the elevation thereof. The forwardends of the side pieces of broiler pan support 40 are pivotally connected' at 45-V to arms 46, which extend downwardly and rearwardly andV have their rearportions pivotedat 41 to brackets 25. This construction is such that as the inner end of the support 40 is moved or adjusted to any prede-VY termined elevation, the arms provide for maintaining the entire structure 40 inra substantially horizontal position, and at the elevation determinedbythe adjustment of ,the inner end. To

insure movement of the structure in this path and the prevention of any twisting, stabilizer cross bar 50 is employed. Thisbar extends across the entire width of the Vbroiler chassis 20 and is journalled onV either side in holes 5I formed in brackets 25, and has'itsipo'rtions outward of these supports forwardly turned at 52. The Vends of these forwardly'turnedV portions have projections extending inwardly as shown at 53, and these. are receivedin slots 54 which areformed by depending U-shaped brackets 55 attached Vto the rearward portions of the side pieces of broiler pan support 40. It will be understood that stabilizer bar 50 serves to maintain both sides of the frame at the same elevation throughout adjusting Vmovements thereof and provides for obtaining a Vfirm andrigid structureV which can be fabricated from light weight sheet metal parts.

In order to effect the adjustment Vinrelevation of the broiler pan support from outside;V the broiler compartment,.themember 53,1at one side of the frame,is formed with an outwardly pro'- jecting portion 51, anda roller 58 is pivotally mounted on this overhanging end.'V The'roller runs' within a channelshaped trackgor guide member 59, positioned adjacent the interior wall of the oven or broiler compartment. The guide is' pivotally attached to the oven wall by` means located adjacent the forward part of the compartment, the inner end of the guide being free and adapted to occupy .different angular positions, at varying elevations. The outer end of Vthe guide, being relatively close-to the point of support, maintains substantiallyV the same elevation at all angular positions of the guide within its range of movement. e Y' Y The pivotal supporting means for the guide includes a reinforcing member 60 fastened into the sidewall of the stove, preferably between Yspaced wall plates thereof, this member having substantialV areaiin contact-With the wall; plates aioaso tached to the guide so that the two parts pivot together. The operating member 52 is formed with a pair of downwardly extending fingers 63, lying respectively on opposite sides of Va vertical axis through pivot 6|. A shaft 64 is rotatably mounted within reinforcing member 'Bll), the Aouter Vend extending to the exterior of the oven compartment upon which is fastened the manually s adjustable knob 65. The inner end of the'shaft has fixed thereto Van eccentrically formed camming Vmember 66 which is positioned between i and'iri' operative engagement with the fingers 63.

'IhusV upon rotation of shaft 64, the eccentric member 66 will be rotated into engagement with one or the other of fingers 63, to causethejpivoting of the entire guide 59 about pivot 6|, with resultant adjustment "of the elevation of the inner end of the guide. The Vguide is held in any desired adjusted positionas a result of frictional engagement Vbetween the parts of the operating mechanism; if desired a yieldable ratoheting means of suitable character may be as- Sociated withi shaft 64 to additionally providev for retaining the same in any Vadjusted position. Also suitable indexing means may be associated withroperating handle 65 to indicate the position of the broiler pan withinthe oven.

'I'he Voperation of the device should be clear from the above description. With the broiler -device in itsoperative' position within the com- Lpartnrent, changes in elevation thereofare effected under the control of the externally operable adjusting knob 65. VThis knob is conven- Viently positioned` adjacent the lower front portion of'the oven" sol that it is .readily accessible for Vthe operator. Upon rotationrof this knob, camming lmember 6B ,engages Vone ortheV other of the fingers 63? to` cause pivotal movement of Vguide 59.V v VSuch Vpivotal movement results in either raising or lowering the Vinner end of the guide, with a corresponding raising Vor lowering of'A roller '581 f Such motion is transmitted directly to the adjacent projection 53, and byV means of the reinforcing bar 50, to the member 53 1ocated upon the opposite side of the frame. Motion'of these two members thus results inV the raisingY or lowering of the inner end ofthe frame Y support, and adjustment thereof to the desired elevation, and ,theY linkage mechanism previtially horizontal positionv at` thedesired elevation.

`When it is desired to withdraw the broiler devcefas for' instance to obtain access to the'broiler pan support, the entire assembly including the frntclosure I9V is drawn outwardly upon the supporting rollersv 30, 33.V As a result of such movement, roller 58 travels forwardly in the guideV 5.9, meanwhile effecting the lowering'of the broiler pan: support frornfwhatever position of adjustment it occupied. In thernormal outer po- 'sitionofv theV device, .the roller 58 has traveled along guide`59 to substantially the pivotal axis thereof, at which positionV the broiler frame is in itsllowerinost position of adjustment as determined`r bythe verticallength ofY the slots 44. Thus regardless of the position of. adjustment of the elevating. mechanism, the broiler' panv a1.-

of, an adjustable guide member positioned at ways assumes its lowermost position of adjustment when the drawer is fully open. And in this position, if desired, the entire assembly may be bodily withdrawn from the stove, roller 58 running out of the open end of guide 59. And upon replacement of the broiler assembly within the compartment, the parts are maintained in such position that easy and quick assembly is permitted. The forward end of the guide 59 is spaced inwardly of thecompartment a short Y distancek from rtheY ends of the Vtrack'memb'ers 35, and as a result the rollers 33 vfor supporting the entire frame are first engaged 'upon' their tracks 35. 'As' the broiler structure is further moved into Aposition vwithin the compartment, roller 58 automatically engages directly within the guide 59, Whatever the position of adjustment thereof. Similarly rollers 3i) engage and support bottom plate 22. If the adjusting mechanism has been actuated to raise the inner-end of guide 59, the further movement of the broiler assembly into the compartment will result in the gradual; lifting of the broiler pan support up to the desired nal operative position. Suitable means may be provided for yieldingly retaining the broiler assembly in its inner'V operative position, and in a withdrawn position providing for access to the broiler pan support.

'I'hus the invention provides a mechanism operable for adjusting the elevation of a broiler pan support, the mechanism being highly effective in operation and simple in construction.' Adjustment of the elevation is effected by means of a control member mounted upon a stationary part of the stove, and interconnecting means for effecting adjustment in the elevation of the broiler assembly, while at the same time permitting immediate and unencumbered withdrawal of such broiler assembly from the compartment.
