OVEN.
Application llled February 8, 1923. Serial No. 617,765.
To all whom it may concern:
Be itknown that I, HERMAN M. BIEBEL, a citizen of the United States, and a resident of Oakmont, in the county of Allea relatively simple, compact, easily manufactured and easily assembled electricallyheated oven for heat treating materials.
In practicing Vmy invention, I provide a plurality of plane heat-insulating panels which are so mounted relatively to each other as to enclose an oven chamber that is of substantially rectangular form in longitudinal t section and ot substantially square formpin lateral section. A sha-ft is rotatably mounted in the oven structure and carries av plurality of circular materialsupporting means. t
Electric hea-ting elements are located in the corners of the oven structure closely adjacent to the outer periphery of the material-supporting means Land are of arcuate contour in lateral section. Suitable reflecting means are located back of the respective heating elements.k
Batlle plates are mounted on the oven structure and extend from the inner surfaces of the respective walls to Within a short distance of the shaft.
In the drawings,
Figure 1 is a.l view, in vertical section, of an oven embodying my invention,
Fig. 2 is a view, in horizontal 'section therethrough, taken on the line II-II of Fig. 1, and
Fig. 3 isa. view, in horizontal section therethrough, taken 0n the line III--III of Fic. 1.- n oven structure 1() comprises a skeleton supporting frame 11 which is provided t with a. plurality of suitable supporting members 12. f An intermediate plate 13 may be employed to stillen the skeleton structure "and also serve as a support for an operating means.
A plurality of heat-insulating wall. panels 14, comprising the side and rear walls, each comprise inner and outer metal sheets spaced` apart by ,a suitable thickness of heat-insulating material. The specic construction of the heat-insulating walls terms no part of my invention, and is, therefore, not further described or illustrated inrdetail. The side and rear panels may be suitably secured together at their edges by angle bar members 15 or-by any other suitable or desired construction which will operate with the heat insulating panels t0 form a suiiciently rigid oven structure. i
-A relatively narrow front panel 16, that co-operates with a door panel`17 to enclose the front of an oven chamber 18, a top heat lnsulating panel 19, and a bottom heat insulating panel 21, are provided to co-operate with the side and rear wall panels to totally enclose the oven chamber 18.
The panels 14 are substantially rectangular in contour and of plane construction and the width of the two panels 16 and 17 is substantially the same as the width of one of the panels 14, whereby the lateral section of the oven chamber 18 .is of substantially square form.
A shaft 25 is located centrally of the chamber 18 and is rotatably mounted in bearing members 26 and 27 located respectively in the panels 19 and 21. The shaft 25 extends through the lower heat-insulating panel 21 and therebeyond and has mounted thereon a worm 28 which is ope-ratively engaged by a'worm .gear 29 mounted on the shaft of a suitable driving means 31, here illustrated as an electric motor located on the plate 13 of the supporting means. A plurality of trays 32 are mounted on shiftableI skeleton frames 38 that are located in spaced relation on the shaft 25.
If desired, the trays 32 may be of substantially circular contour and of unitary construction and be nonremovable from the supportingframes 33. The trays V32 may, however, be made segmental in construction and be removable from the supporting frames 33. In the latter case, I prefer to employ four arms in each of the supporting frames 33 in smaller ovens and a larger number of arms in relatively large ovens,
the number, of course, being dependent upon the material to be placed upon the respective segmental trays and the ease of removing and otl inserting the same by the operator.
A plurality of electric heating elements 3st, 35, 3G and ST, each of arcuate shape in lateral section and et any suitable or desired construction are located in the oven chamber 18, in such position as to lie closely adjacent to the outer periphery of the material-supporting members As hereinbefore stated, the heating elements may be of any suitable or desired construction, the main consideration being that at least three of the heat-ing elements, viz, those designated by the numerals 35, 3G and 3T shall each be ot such arcuate. extentas to cover substantially one-fourth of the periphery. As it is necessary to remove the material through the opening` provided by the hinged door panel 1?, the heating element is made of relatively small arcuate extent. The capacities of the heatingelements S53, 36 and 3T may be oi respectively increasing value, that is, the amount ot' heat generatel by the heating element 8lis relatively small because of its small size, the amount oi heat generated by the element 35 is larger and the amountof heat generated by the element 3T is the maximum tor the series.
Each of the heating elements extends sub stantially from the bottom to the top et the oven chamber 18. Reflectormembers 5S, also oit arcuate form in lateral section, are placed baclr of the respective heating elements, are substantially cosextensive therewith, and reliect a portion ot the heat rays therefrom, against material which is placed upon the trays 32.
Aplurali y of baille plates 39 extends inyvardly from the respective panels 14 and 16 and are here shoivn as four in number, although any suitable number may be employed in order to provide any plurality of compartments Within the oven chamber 1S that may be maintained at diierent temperatures, if required by the heat treating processes to which the materials are to be subjected. The baille plates 39 serve also to restrict and to reduce the cooling effect of the opened door 17 when materials are removed from or placed within the oven chamber 18.
The oven embodying my invention may be employed for a variety of heat treating purposes. For instance, I may construct the oven as a balre oven tor bread or pastry, in vvhich case the shaft Q5 extends in a vertical direction substantially as illustrated in the drawings. By varying the capacity of the heating' elements and `gradually increasing them, I am able to subject the materials placed on the material carrying means to a gradually increasing temperature. If it is desired to subject the material to decreasing temperatures, it is, of course, only necessary to reverse the direction of the shaft 25 and of the material-carrying means supported thereby.
The oven embodying my invention may also be employed Yfor other purposes, such as core baking and Where it is necessary to balie a large number otthe same type of cores, the width of the battle plates 39 may be made such as to just permit the material to move therebelow duringr the rotation of the shaft 25 and it the baille plates Si) extend upwardly relatively close to the under surfaces oit the material-carrying means, a suliicient separation of theoven chamber into compartments is etli'ected, which coinpartments may be maintained at different temperatures.
Il it is desired to construct an oven in which the shaft extends in a horizontal direction, this may also be accomplished prmidingr thaty the inaterial-carrying means is suitably changed to permit; ot mounting thereon the material to be heat treated.
The device embodying my invention employs a plurality ot plane heat insulatingr Walls that are easily constructed and that are easily and quickly assembled. The material-carrying means located in the oven chamber enclosed by the plane heat-insulat ing Walls are of substantially circular con tour and when located Within the oven chamber 18, of substantially square shape in lateral section, permit of mounting within the oven chamber in the corners thereof, heatingr elements of arcuate shape in lateral section. which heating elements occupy what is otherwise unused space within the oven chamber. In other Words, by suitably selectingr the dimensions of the substantially circular material-carrying means, of the heat-insulatin;T panels. and of the heating elements, I obtain a relatively compact oven structure, a plurality of which may be lo cated in side-by-sidc relation or back-to-back relation. and will. therefore, occupy a mini mum amount of floor space.
Various modifications and changes may be made herein without departingr from the spirit and scope ot my invention. and I dei sire. therefore. that only such limit-ations shall be placed thereon as are indicated in the appended claims or are imposed by the prior art.
I claim as my invention:
1. In an oven, in combination, a plurality of heat-insulatingr panels enclosing; a substantially rectangular oven chamber, means for moving material in a substantially circular path in said chamber, and a plurality of heating elements. of arcuate form, located in the corners of said chamber.

In an oven, in combination, an oven chamber, of substantially rectangular shape, flat heat-insulating panels surrounding the same, means for movin material in a substantially circular path 1n said chamber and a heating element of arcuate form located in a corner of said chamber closely adjacent to said material moving means.
3. In an oven, in combination, a plurality of heat-insulating panels enclosing a substantially rectangular oven chamber, means for moving material in a substantially circular path in said chamber, and a plurality of heating elements, located in the corners of said chamber, said heating elements being of such form and extent as to 'lie closely adjacent to and outside of said path of travel and to cover the major portion thereof.
4. In an oven, in combination, a plurality of flat heat-insulating panels enclosing an oven chamber of substantially rectangular shape, means for moving material in a substantially circular path in said chamber, a plurality of heating elements, of arcuate form, located closely adjacent to and outside of said circular path and extending across the corner portions of said chamber, and reflector members, of 'arcuate shape, located outside of said heating elements.
3u 5. In an oven, in combination, a plurality of flat heat-insulating panels enclosing an oven chamber of substantially rectangular shape, means for moving material in a substantially `circular path in said chamber, a plurality of electric heating elements of arcuate shape and of progressively increasing heating capacit located circumferentially of said circu ar path in the corner portions of said chamber, and means in said chamber for restricting the heating elect of a heating element to a predetermined portion of said oven chamber.
6. In an oven, in combination, a plurality of flat heat-insulating panels enclosing an oven chamber of substantially rectangular shape, one of said panels having a door portion therein, means for moving material in a substantially circular path in said chamber, a plurality of electric heating elements, of arcuate form, located closely adjacent to said circular path and extending across the-corner portions of said chamber, and means in said chamber for limiting the cooling effect of the opened doorto a predetermined portion only of said chamber.
