11 Claims. (01. 126-39) This invention relates to ranges, and more particularly to electric ranges and to ranges adapted to burn gas, tank gas, gasoline, kerosene and the like.

One of the objects of the invention is to provide a range of sturdy and compact construction which may be formed of aw parts and assembled with fewer operations tharrheretofore required. Another object is to provide a range frame of staunch construction upon which most of the parts are supported in such a manner that they do not carry the weight of other parts. A still further object is to equip a range with a hot plate 1 or working top, which may be supported over the oven compartment, and when not in use, may be covered with a hinged top. Another object is to provide a range compartment having linings compactly but releasably held therein, the linings being removable through the top portion of the range. Yet another object is to equip oven linings with improved means for supporting trays therein. Another object of the invention is to provide a range with a hot compartment in which heat from the oven compartment may be utilized. A further object is to provide a range equipped th sliding sheet-ends, the sheets being releasbly secured in position with a. minimum of ficrews or other fastening means, and affording '6 easy access to insulation strips which may be supported between the sliding sheets and oven wall. Other objects and advantages will appear as the specification proceeds.

The invention is fully described in the following specification and shown in the accompanying 35 drawings, in which- Figure 1 is a perspective view of a range illustrating one embodiment of our invention, one of the range covers being raised to expose a hot plate or working top; Fig. 2, a sectional view, the

I

In the illustration given, and referring particularly to Figs. 2, 3 and 5, the skeleton frame of the range is preferably formed of angle iron bars or strips. A perimetric top frame is formed with the angle iron strips 10 forming the front and rear sides, and the angle iron strips 11 forming the ends of the frame. A similar perimetric frame is also formed at the bottom of the range, the latter frame, however, facing in the opposite direction. In the bottom frame, the angle iron strips 12 form the front and rear walls of the frame, while the strips 13 form the ends. The corner posts of the range are also formed of angle iron strips 14, as shown more clearly in Fig. 5. Preferably, the top perimetric frame is divided along a median line by a transverse angle iron strip 15.

The range is provided with a rear wall 16 and sliding end walls or. sheets 17. The end walls or sheets 17 are provided with inwardly turned flanges 18 which engage the rear wall 16. The method of securing end walls 17in position will be hereinafter described.

The front wall of the range may be formed in any suitable manner. In the illustration given, the front wall is equipped with a vertical post 19 near the center of the front wall and with a plurality of horizontal beams connecting the central posts of the frame. Hinged doors 21, oven door 22, and together with the trim closed front'wall of post 19 to the side doors 20, slidable broiler drawer front 23, or border strips make up a the range.

The range is divided into two main compartments by central partition 24. A burner cornpartment A is formed by partition 25 which connects the partition 24 to the end wall 17. Bumers 26 of any suitable type are supported in the burner compartment above partition 25. A bumer top or grate 27 of any suitable construction is supported by angle irons 10, 11 and 15 over the burners. g 1

Compartment B, below the burner compartment A, may be provided on its outer side with a lining 28. Lining 28 and partition 24 are pref erably equipped with supporting brackets 29 adapted to carry a tray 30. Compartment B is provided with a bottom wall 31.

The oven and broiler compartment C, on the opposite side of partition 24, is provided with end and rear walls 32 and 33 respectively. Insulation, Of any suitable type, may be employed between the walls 32 and 33 and the outer casing walls 17 and 16.

As shown more clearly in Figs. 3 and 5, the oven and broiler compartment is equipped with side lining members 34a and 34b, the flanges 35 of which are turned outwardly toward the sides of the compartment, thus affording an air space between the inner wall of the lining members and the wall 32 and partition 24. The side lining members 34 are securely locked in position against walls 32, 33 and 24 by the oven bottom 36 which is suDDQrted at the rear by lug 36a on rear wall 33 and lugs 36b on the front cross beam 360. The top of the oven compartment is formed by a casing member 37 containing insulation of any desired type and thickness. The member 37 rests upon the flanges 35 of the lining members 34. The oven bottom 36 is preferably-formed of sheet 38 provided with end flanges 38a and is supported by a deflector plate 39. The plate 39 is preferably bent along a median longitudinal line and has its side portions inclined slightly upwardly. Longitudinalslots 40 are formed along the sides of the bottom member 36 to permit the heated gases from the burner 41 to pass into the oven compartment.

A broiler drawer 42, equipped with extension slides 42a, may be supported below burner 41 in the. lower portion of the compartment.

In order to support a tray 43 within the oven compartment, we prefer to e ploy the'following mechanism. The inner walls of the linings 34 are perforated to receive the ends of bracket members 44. Preferably, the ends of the members 44 are reduced and extended through the walls of the-lining, the portions of the members extending through the wall being threaded to receive retainingnuts 45. The tray 43 may be provided with any suitable means for releasably engaging the bracket rods 44. As illustrated more clearly in Figs. 3 and 7, the sides of the tray 43 are provided withlateral extensions 46 adapted to engage the top ofv bracket members .44, and depending arm projections 47 adapted to engage the under side of bracket rods 44. With this construction, the tray 43 may be securely held in position upon the bracket 44 when the tray is almost withdrawn from the compartment and may, when desired, be completely withdrawn from engagement with the brackets 44. I

Within the perimetric frame afforded by the angle iron members above the oven compartment, we prefer to employ a hot plate or working top 48. The member 48 is preferably dished, although it may beformed in other shapes. Plate- 48 is covered by hinged top 49. ,A similar hinged top covers the burner top 27'. The hinged tops 49 and 50 are preferably provided with a layer of insulation 51.

In order to secure the hinged tops 49 and 50 in raisedpositions, springs or counterweights of any suitable type may be used. In the illustration given, a spring 52 is secured at its lower end to bracket 53 and at its upper end to the rear wall 54 of the range top 50. A similar spring is used to facilitate the raising of top 49.

In order to utilize the heat of the oven compartment for heating the warming or hot compartment B, we provide shutter or other suitable means for establishing communication between the compartment and the air space between lining 34 and partition wall 24. In the illustration given, a shutter 55 is slidably secured between. partition 24 and spacll flanges 56, and upon being raised, is adapted to close a longitudinal window 57 in partition 24. The metal strip 57:: struck from partition 24 to provide window 57 is preferably tumed so that its free edge engages the wall of lining 34a, thus sealing off a portion 340 of the lining above wall 57a, which lining portion may, if desired,- be filled with insulation. A metal strap or link 58 is secured to the top of shutter 55, and at its other end is secured to lever 59. The lever 59 is pivotally supported upon post 60, the outer end of the lever extending through a slot 61 in the burner panel 62. At the lower end of. slot 61 is an offset shoulder 63 which is adapted to be engaged by lever 59 to hold it in depressed position. With this arrangement, the

shutter may be raised and lowered from without 1 the burner compartment.

In order to secure the end walls or sliding sheets 17 releasably in position, we prefer to employ the I following construction. A cooking top strip 64 is secured at the upper side of each end of the range and is provided with an under-cut edge 65, as shown more clearly in Fig. 4. A similar base band strip 66 is secured at the bottom of each end of the range, and is similarly provided with an under-cut portion 65. Preferably, each of the front column support strips 67 is provided with grooves 68 adapted to receive the sliding sheets 17, as illustrated more clearly in Fig. 5. The sheets or end walls 17 are adapted to engage the grooves formed by under-cut edges in the cooking top strip and the base band strip and the grooves 68 in the front column strips, the rear flanges 18 of the sheets 17 being brought flush against the rear wall 16. Sheet metal screws 69 are preferably employed to secure the-sheets 17 to the rear wall 16, and to the angle iron posts 14,

two screws being ordinarily suflicient to secure,

each of the strips 17 in position. Ready access to the insulation and lining enclosed by ends 17 is thus afforded upon the removal of screws .69.

Any suitable form of burner panel and burner panel doors may be employed. As illustrated more clearly in Fig. 8, the burner panel 62 is recessed or dished so that the burner handles 70 are supported back of the front line of the range. A heat regulator 71 of any desirable construction may also have its dial supported by burner panel 62. The burner panel 62 is preferably equipped at itsends with flanges 72 to which are secured doorhinges 73. The outer flange of each hinge 73 is secured to a block 74 which is apertured to receive the slide rods 75. Slide rods 75 are fixedly secured at their ends 76 to folding'doors 21.

The gas pipes which supply gas to the burners in the top burner compartment and to the burner in the broileroven are preferably concealed within the range compartments in such a manner that they are readily accessiblefor repair. The main gas inlet pipe 77 extends through the rear wall of the range and curves mong the front burner panel so as to supply gas to the separate burners. The gas, control 79 for the oven controls pipe 80 which extends under the mixers 78 and descends along partition 24 until it reaches the burner 41.

With this construction, the gas pipes are all housed within the burner compartment A and the warming compartment B, and are readily acces sible.. t

An oven flue ofany suitable type may be used. As illustrated more clearly in Figs. 2, 3 and 5',

an outlet pipe 81'leads through the -rear wall 33' and communicates with a flue fixture 82 wall 16. 1

In the operation of the range, the top'50 is On rear ra s d '60 a vertical position, and the doors 76.

"4,980,807 are opened. In opening doors '16, they are swung forwardly until perpendicular to the front wall of the range andthen pushed back, the slides '15 passing through the guide blocks 73 to assume the position shown in dotted lines in Fig. 8.- The burners may then be operated in the usual manner. T

If it is desired to use the plate 48 as a work- .ing top, the cover 49 may be raised. Dishes, pans,

etc. may be placed upon the plate 48 without fear of marring the finished surface of cover 49. When the oven is heated, the plate 48 also becomes hot and serves to keep warm foods removed from cooking tori 51. The temperature of plate 48, relative to the oven temperature, may be predetermined by the thickness of the insulation block 37 between the oven and the plate. When plate 48 is not in use, the cover 49 may be lowered and the air space between the bottom of pan 48 and cover 49 serves as additional insulation to maintain the top of cover 49 cold.

After food has been cooked and it is desired to keep it in warm condition until ready to be served, it may be placed upon tray 39 in the hot compartment B and shutter 55 may be lowered by releasing lever 59- from engagement withnotch 63, the

.weight of the shutter causing it to assume the lowered position. Window 5'? now permits the heated air between the linings 34a. and 24 to pass therethrough and to heat compartment B. At the same time, the vapors, gases, etc. from the oven are excluded. When it is desired to use compartment B as a cool compartment, the shutter 55 may be raised and held in raised position by bringing the outer end of lever 61 into engagement with shoulder 63. If desired, the space below tray 30 in compartment 3 may be used for storing kitchen utensils, pans, etc.

If it is desired at any time to remove the oven linings 34, this may be accomplished by raising top 49, removing plate 48 and the top lining 37, and lifting the oven bottom 36. through the top of the range.- The linings 34 may then be lifted out. In reassembling the parts, the oven linings 34 may be dropped in position through the top of the range and then keyed or locked in position by bottom lining 36. The top lining 37 may then be placed upon the top ends of oven linings 34 and plate 48 placed back in position.

When it is desired to remove the lining 28 or the insulation between walls 17 and 32, the sliding end walls 17 may be withdrawn rearwardly upon the removal of screws 69. After the insulation has been replaced, the sheets 17 may be slid back into position until flanges 18 engage the rear wall 16. The flanges 18 may then be secured to the rear wall 16 and to angle iron standards or posts 14 by screws 69. If enamel is chipped oil of the ends 1'7, they may be readily repaired without requiring disassembly of the range. Also,

with the construction shown, the edges of the ends 17 are protected, the force of any jar or blow, during shippage, being taken up by the angle iron frame.

With the angle iron frame construction illustrated, the end sheets 1'! support no weight. This is also true of other parts, such as the doors, burner box panel, the two lift tops 49 and 50, etc. In addition to providing a range of sturdy construction, a large number of parts heretofore required in ranges of this character, have been eliminated, and the number of operations required in the assembling of parts greatly reduced.

While the invention has been illustrated in connection with a range of the cabinet or console .vertical flange and a lower horizontal flange, a

type, it is obvious that various phases of the invention may be embodied in ranges of other types, as for. example, in ranges of the Tiffen The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom, but, the appended claims'should be construed asbroadly as permissible in view of the prior art. i v lweclairh: W.
