Application June 9, 1931, Serial No. 543,039

6 Claims. (Cl. 126-273) This invention relates to ovens for stoves and may constitute an improvement in portable ovens as well as in ovens that mean integral part of stoves.

Certain foods are very satisfactorily prepared by baking, butwhere only a single small utensil is required, a cook may hesitate to heat an entire oven for the sake of baking so small a quantity of food. If it were possible to limit the heat to 1Q the portion of the oven really needed, an oven "would be used more frequently.

The primary object of the present invention is to provide partitions which may be adjusted within an oven to form an enclosure which may be heated independently, of less than the full size of the oven. A further object is to provide heating means arranged to heat only a portion of an oven. Other objects include the provision of simple, economical, and efficient means for retaining the various parts in both their operative and their inoperative positions. I p the description proceeds, it will be evident that the invention is not limited to the exact details of construction of thespecificelements chosen for illustration as a preferred embodiment of the invention for the purposes stated, but many changes, substitutions, and. modifications may be made by one familiar with the art without departing from the principles of the invention as claimed.

In the drawing, which shows a typical form of oven adapted for use as a permanent part of a 7 gas range, Figure 1 is a perspective view shown with the door as opened and with portions of the walls broken away to reveal parts otherwise conceale'd; Fig. 2 is a perspective view of the oven as seen from one side of the bottom; and Fig. 315 a fragmentary side elevation of the smallest partition, showing in solid lines the position it occupies when not in use, and indicating by broken lines the position it occupies when brought into active service.

The oven is shown as having a floor 1, a top 2, a back 3, side walls 4 and 5. and a door 6, all of which may be of any well known or suitable construction. Mounted within the upper portion of the oven is a shaft '7 having secured thereto, near its ends, cords or cables 8 and 9 which have their other ends attached to a horizontal partition 10 near its front edge, and cables 11 and 12 which extend from the shaft 7 over pulleys l3 and 14 to the same partition near its rear edge. A crank 15 on the outer end of the shaft 7 serves as a means for rotating the shaft to wind the ends of 55 the cables thereon to lift the partition 10 from the position shown in solid lines in Fig. 1 to the upper position shown in broken lines in the same figure.

' A transverse partition 16, hinged at its upper edge to the under side of the horizontal partition 80 10, may be held, when not in use, horizontally as. indicated by broken lines in Fig. 1, or may be placed vertically as shown in solid lines, with its lower edge in contact with the floor 1. V

A partition 1'? mounted at right angles to the door 6, is also shown as hinged to the lower side ofthe partition 10 to lie parallel thereto when .not in use, as indicated by broken lines in Fig. 1

or in solid lines in Fig. 3. When in use, it hangs vertically as indicated by solid'lines in Fig. 1 and by broken lines in Fig. 3.

In Fig. 2, the gas burner 18, controlled by valve 19, is shown as extending across the rear 'half portion .of the oven, beneath the floor 1. The burner 20, controlled by the valve 21, lies beneath the right hand portion of the front half of the oven and the burner 22, controlledby valve 23, lies beneath the left hand portion of the front half of the oven.

It will be seen that with the partition 10 lifted to the upper or broken line position of Fig. 1 and with the partitions 16 and 1'7 folded parallel thereto and latched to hold them securely in place, the entire oven is available for usesubstantially as if the movable partitions were not there. All of the burners, 18, 20, and 22 may be used together, or any combination found suitable.

With the partition 10 lowered to the full line position of Fig. l, but with the partitions 16 and 1'1 still folded horizontally, the lower half of the oven will be available for use with all or some of the burners.

When the partition 10 is in its lowered position, the partition 16 may be swung downward and forward to shut off the rear half of the oven portion below the partition 10. This partition 16 extends from one side wall to the other to make a complete closure between them, as it also formsa complete closure between the 'partition lama the floor 1. The burner 18 need not be used with this adjustment, since it would heat only the space behind the partition 16, but instead, the two burners, 20 and 22, beneath the front portion of the floor will heat the front quarter of the oven between the partition 16 and the door 6 and beneath the partition 10.

If a still smaller space is enough for some special dish, the partition 1'7 'may be lowered as indicated by the arrow in Fig.3 to divide the 11 front quarter of the oven described above into two separated spaces, either or both of which may be heated at will by the use of the burner or burners necessary. The temperatures may be made different in the two chambers by proper regulation of the controlling valves, and it is evident that much less gas will be needed to maintain a given temperature in either of these eighth volume spaces than wouldbe required for the whole oven.

The partition 17 is shown as having two walls, 24 and 25, to furnish a passage for heated air from the space beneath the floor heated by the burner 22. The floor 1 has an opening closed by a small door 26 hinged to swing upward. A rock arm 27 operated by a lever handle 28 may be used to lift the door 26 out of the opening in the floor, and when the partition 17 is swung down.

into place, the door 26 may rest against the side of the partition as shown in Fig. l.

; The partition-17 is providedwith upper and lower air vents 29 and 30 to aid in the. circulation of heatedair around the smaller chamber at. the left of which itforms a wall,. corresponding openings 31 being formed in the inner panels 32 of the main side walls of the oven.

A It will be understood that the partitions may be made of any suitable material ,or layers of materials and that the showing herein is merely diagrammatic. The art of heat insulation is well developed and it is not deemed necessary to illustrate any specific form since obviously any desired construction may be used which will not prevent the operation of the movable partitions. The latches 33 indicated as or a simple spring latch type may be replaced by any suitable means for holding the partitions in inoperative position. i It is also to be understood that any other suitable source of heat may be used inplace of the gas burners illustrated, the details of COI'lStIlICf tion herein shown being selected as merely a typical grouping of parts suitable for the accomplishment of the purposes oi the invention as claimed.
