STOVE Filed Feb. ,28, 1951 l:s `sheets-sheet s Patented-May 31, 1938 UNITED STATES PATENT OFFICE STOVE Bertrand B. Kahn, Cincinnati, Ohio, assignor to The Estate Stove Company, Hamilton, Ohio, a

corporation of Ohio One of the principal objects of the invention is to provide an improved construction in a stove for facilitating the handling of the foodstuffs;l

and permitting of suitably inspecting, positioning and handling of the foodstuffs even while the oven is being heated.

Another object of the invention is to provide an oven arrangement comprising a slidable drawer containing a food supporting member, and means for adjusting the food supporting member vertically independently of the drawer sliding mechanism.

. Other objects and advantages of the invention will be apparent from the description` thereof set out below and from the accompanying drawings and the appended claims.

Fig. 8 is a partial side elevational view of the oven shown in Fig. '7.

In the drawings, which -illustrate.a preferred embodiment of the invention, asv incorporated in a stove, the main body of the stove is designated by the numeral III, one of the several supporting legs of which is shown at II.. The main body of the stove and the remaining features thereof need not be shown to afford a complete disclosure 'of this invention and therefore only a small fragment'oi the stove body surrounding a single oven, is shown. The legs II are conveniently made adjustable in height so that the stove may be positioned at just the right height for the individual operator. Suitable heat insulating material is provided for exposed oven walls, as indicated by the numeral I2, such material being of any suitable, known character.

The oven is provided with a slidable and preferably removable drawer member which carries mechanism for supporting the broiler pan or tray 5 in vertically adjustable relationship within the drawer member. This drawer member comprises a front member forming a closure for the compartment when the'drawer is in closed position, and having spaced walls I5 and I6, between 10 which is heat insulating material, and which forms a closure for the broiler compartment when the drawer member is closed.

A metal plate I8 is bolted by suitable bolts I9 to the end wall I6 and spaced therefrom a su- 15 cient distance to form a compartment housing the pan elevating mechanism, the sides and top of the plate being bent at right angles to its face so that the mechanism is completely enclosed. The inner end of the drawer is formed by bolt- 20 ing together two bent sheets of metal 20 and 2|, the former also being provided with right angularli7 bent side and top portions so that between them they form anenclosed compartment for the pan elevating mechanismI at this end of the 25 drawer.

The sides of the drawer are shallow and are formed of metal strips 22 which are bent outwardly at their upper edge to form a ange 23 and are bent inwardly at the lower edge 24 to 30 form a supporting portion. The plate, I8 is y formed with right angularly bent projections 25 at its lower portion which are attached to the y support 24 in a convenient manner such as by welding. Likewise the metal sheets' 20 and 2| 35 forming the inner end wall of the drawer are made with right angularly bent projections 26 and 21 which are also welded to the support 24.'

- Rollers 28 are mounted on the vertical portion of the strips 22 at the inner end thereof and 40 form the support for the inner end of the drawer member.

A track member is mounted within the oven' compartment, this track being shown 'as a strip of metal 30 having a bent over flange 3l which 45 is attached to the interior wall of the broiler compartment by suitable means, such as rivets p 32, the body portion being thus spaced therefrom. a short distance. This metal stripextends along the compartment wall from the front to 59 back and the lower portion is bent to form a horizontally extending portion 33 which serves as a track upon which the rollers 28 supporting the rear end of the drawer ride. Beyond the track portion. 'the strip is again bent downward- 55 ly at 34 for attachment to the stove framework.

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 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 ange 23 of the drawer. The flange 23 thus serves as both guiding and supporting 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 forl5 ward position of the drawer. This represents the normal movement ofthe drawer and when in this position, the pan is practically clear of the oven so that it may be readily removed. It will be noted that the side walls of the drawer are 420 quite shallow and that the pan, even in its lowermost position, is supported above the side wall and consequently may be easily. grasped at the sides and removed.

^ When it is desired to withdraw the drawer farther, 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 are of such size and are so positioned that the roller 28 willnot pass under the roller 31. Consequently there is no danger, even when the drawer has been removed to its extreme outward position, of having the same fall out of the oven unexpectedly. 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 entire drawer may be withdrawn completely. Mounted in the front member of the drawer is a shaft 52 adapted to be rotated in suitable bearings 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 xed to shaft 52 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. 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 pinion 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 of the gear.

A lever 6I is xed 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. 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 that the pivot points shall not extend into the oven or interfere with the removal of the pan, 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 the two arms will move in unison, for any movesegmental gear.

by any suitable means and is engaged by a spring ment imparted to the arm 63 by lever 62 will be transmitted to and will produce a similar movement in arm 64.

It will be understood that the thickness of the parts used in the operating mechanism is necessarily restricted to relatively narrow limits inasmuch 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 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 overlie, on each side, the portion of the gear faces 69, 10 which are in engagement with each other.

' This support on each side of the gear teeth eiectively insures against any possibility of slippage or of the gears becoming misaligned.

Slots 14 are formed in plate I8 and are adapted to receive projecting lugs 15 formed on pan 16, which lug's rest upon the supporting arms 63, 64. '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 bending 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 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 provided with depressions 81, 88 so that the pivot 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 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 guidind the pan during its vertical movement.` 4

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 rotational movement to the shaft 56. Levers 6I and 8|, xed 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 to this movement, the arms 64 and 84 are likewise In the arrangement just described, the single handle 50 serves two purposes. It provides a 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 functions are entirely distinct and independent,l and therefore a modified form of the invention is illustrated in Figs. 5 and 6 wherein separate handles and |0| are provided, the former being 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 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 illustrated in Figs. 7 and 8 wherein a dial |04 is mounted upon shaft 52 (not shown), while the larger handle serves to move the drawer laterally 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 ngers. Suitable 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 to position the pan at any desired height, without openingthe drawer, by setting'the indicator on' the dial to the desired point on the scale.
