This metal stripextends sure 'of this invention and therefore only a small fragment'oi the stove body surrounding a single along the compartment wall from the front to oven, is shown. The legs II are conveniently ` back and the lower portion is bent to form a » made adjustable in height so that the stove may be positioned at just the right height for the in dividual operator.

A roller 36 is mounted upon the vertical body portion of strip 30 and similarly another roller 31 is also mounted upon this strip but positioned 5 closer to the -front of the oven. These two rollers are in different horizontal planes and so spaced that there is guiding clearance between them for the ñange 23 of the drawer. The flange 23 thus serves as both guiding and supporting 10 means for the drawer as it is moved into and out of _the broiler compartment. This flange is ‘ also provided with an upturned portion 42 at the extreme inner end of the drawer which serves as a. stop when it engages the roller 36 in the for ment imparted to the arm 63 by lever 62 will be transmitted to and will produce a similar move ment in arm 64. . It will be understood that the thickness of the parts used in the operating mechanism is neces sarily restricted to relatively narrow limits inas much as it is desirable to keep the width of the compartment formed by plates I6 and I 8 as small as possible. Therefore the invention also includes a means for insuring against any possibility of 10 the teeth of the intermeshing faces of arms 63 and 64 slipping out of engagement with each other. This means comprises I projections 12 formed on each link 62 and so positioned as to l5 ward position of the drawer.

' ^ When it is desired to withdraw the drawer far 25 ther, the front end tilted-upwardly to cause the stop member 42 to be depressed and to clear the lower surface of roll 36 and then the drawer may be withdrawn so that the pan will entirely clear the oven compartment. 'I'he rollers 31 and 28 30 are of such size and are so positioned that the roller 28 will‘not pass under the roller 31. Conse quently there is no danger, even when the drawer has been removed to its extreme outward posi tion, of having the same fall out of the oven un 35 expectedly. To completely remove the drawer, the inner end `thereof is raised so that the roller 28 may be moved over the roller 31, and the en tire drawer may be withdrawn completely. ` Mounted in the front member of the drawer is 40 a shaft 52 adapted to be rotated in suitable bear ings 54 and 55 which are formed in the plates I6 and I8 respectively by punching the same and bending over the edges of the material to form a bearing surface. A pinion 5I is ñxed to shaft 52 45 by any suitable means and is engaged by a spring ` detent 56 which is mounted upon the bent over top surface of the sheet I8. This detent yielding 1y engages the teeth of the pinion and serves to hold the same in any position in which it is left. 50 A large segmental gear 58 is rotatably mounted upon a shaft 59, which is carried in similarly formed bearings in both front and rear walls I8 and 20 of the drawer, and which extends the entire distance between these two walls. The teeth of this gear are adapted to engage the pin ion 5|. Projections 60 are formed at each end of gear 58 to serve as stop members when they abut against the pinion .55 in either extreme position 60 of the gear. A lever 6I is ñxed to the shaft 59 within the compartment formed by plates I6 and I8, and is pivoted at one end to two operating links 62, one of these links being placed upon each side of the lever and spaced apart a predetermined distance. 65 The links 62 in turn are pivoted to one of a pair of pan supporting arms 63, 64, which in turn are pivoted at 65, 66 to the plate I8. In order 'I'he slots serve as vertical guides for the pan and keep it in alignment as it is moved up and down in response to a raising or lowering movement oi' arms 63, 64. To provideagainst a possible bend ing of arms 63 and 64, brackets 11 are mounted upon the inner surface of plate I8 andl are spaced therefrom a distance just'suflicient to provide for the vertical movement of the arms 63, 64 but will effectively prevent any horizontal movement or bending of the arms, such as might be caused by a careless person in forcing the lugs 15 against the operating arms in positioning the pan within the drawer. The mechanism at the inner end of the drawer is substantially similar to that at the outer end, with the exception of the operating pinion and 'I'he shaft 58 extends into the rear wall of the drawer and consequently it is 40 _ segmental gear. only necessary to provide a lever 8l pivoted to two operating links A82 which in turn are pivoted to one of the inner pan supporting arms 83 and 84. ‘ - These arms are pivoted at 85. 86 to the inner plate 26 of the inner wall, which is similarly pro vided with depressions 81, 88 so that the pivot 45 point will not extend into and interfere with the positioning of the pan. Links,82 are formed with projections 89 which overlie the intermeshing gear faces of arms 83 and 84 and perform the same function as projections 12 at the outer end 50 of the drawer. Reinforcing brackets 9U are also positioned at the inner end and function in the same manner as do the brackets 11 at'the outer end.’ Slots 8| formed in plate 20 provide for guid ind the pan during its vertical movement.` 4 55 The operation of the pan elevating mechanism is as follows: In response to ,a turning movement o_f handle 50, the pinion 5I causes rotation of a segmental gear 58 which in turn imparts a rota 60 tional movement to the shaft 56. Levers 6I and 8|, ñxed to shaft 59 cause the movement o_f ’the operating links 62 and 82 respectively, which in turn cause the arms 63 and 83 to rotate about pivot points 65 and 85 respectively. In response 65 to this movement, the arms 64 and 84 are likewise ` caused to rotate the same amount about their that the pivot points shall not extend into the pivot points 66 and 86 respectively. This causes oven or interfere with the removal of the pan, the outer ends of all the arms to move either up or down, in the same direction, and to the same degree, Thus the pan, which is supported Vby lugs 'I5 from the four operating arms, is caused to 70 depressions 61, 68 are formed in plate I8 of such a depth that the pivots are indented from the surface of the plate I8. The arms 63 and 64 are formed with intermeshing gear teeth 69, 10 at their adjacent ends and thus it is insured that 75 the two arms will move in unison, for any move 30 be raised or lowered, the same amount at every point and hence'is maintained horizontal throughoutits'extent of vertical movement. 2,119,012 _ ' 3 In the arrangement just described, the single justable handle carried by said wall, a pair of handle 50 serves two purposes. It provides a adjustable pan supporting arms formed at ad jacent ends with intermeshing gear faces, and convenient means for moving the drawer laterally of the oven and at the same time it comprises the external means for vertically positioning the pan. It is of course obvious that these two func tions are entirely distinct and independent,l and therefore a modified form of the invention is illustrated in Figs. 5 and 6 wherein separate handles |00 and |0| are provided, the former be ing mounted upon the shaft 52 (not shown) and adapted to be rotated to vertically po'sition the pan, and the latter being fixed to the front face of the stove and used for moving the drawer 15 laterally. The handle |00 is relatively small and the operator therefore will normally not attempt to withdraw the drawer by grasping this handle but will pull the drawer out by means of the larger handle |0|. Another modified construction has also been 20 illustrated in Figs. 7 and 8 wherein a dial |04 is mounted upon shaft 52 (not shown), while the larger handle |05 serves to move the drawer later ally of the oven. The two handles are positioned relatively close together as shown so that when it is desired to move the dial |04 to adjust the pan vertically, the handle |05 may be used as a con-U venient rest for the hand so as to make it easier to turn the dial with one or two ñngers. Suitable 30 indicating means such as a pointer |06 may be provided on the dial to indicate the position of the pan elevating mechanism. If desired, the face of the drawer may be calibrated in terms of the vertical position of the pan, and thus it is possible CJ El to position the pan at any desired height, without opening‘the drawer, by setting'the indicator on' the dial to the desired point on the scale. While the form of apparatus herein described constitutes a preferred embodiment of the inven 40 tion, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without de parting from the scope ofthe invention which is means establishing an operating .connection be tween said handle and said arms, including links pivoted to one of said arms and formed with a projection adapted to overlap said intermeshing gear faces in all positions of the latter. 5.
