Specification of Letters Patent.

Patented Oct. 111, 1913.

Application led April 21, 1910i. Serial No. 556,870.

To all whom t may concern A Be it known that we, VlRGINIA V. BoLL's and EDWIN R. CRooxnR, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State 'of California, have invented a new and useful Oven, of which the following is a specifi cation.

This invention relates to an oven adapted to be set over a gas stove or other heating means and to be heated by the current of hot air arising from such heating means.v

The main object of the present invention is to provide an oven of this character which can be used for baking, boiling, b'roil' ing and other cooking purposes.

Another object of the invention is to economize as far as possible the heat delivered by the heating means.

A further object of the invention is to provide in an oven of this kind a plurality of compartments and means for separately controlling the heat delivered to the several compartments.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate the invention, and referring thereto: Figure 1 is a front elevation of one form of the oven. Fig. 2 is a longitudinal, vertical section thereof.

Referring to Figs. 1 and 2, the oven comprises a casing of sheet metal formed with a back 1, ends 2 and top 3. The bottom of said casing is open as indicated at 1 and the front thereof has an opening adapted to be closed by a door 5 hinged, in suitable lugs 8 and provided with fastening means 8', said door being hollow as indicated at 5' to provide an air insulation or to receive other suitable heat insulating means. An inwardly extending flange 6 is provided around the bottom of the casing to brace the same, and a bottom plate 7 extends across the casing somewhat above the lower edges of the back and end members, this bottom plate 7 being bent down, as indicated at 7 to rest on the bottom flange 6. A plate 11 extends from end to end of the casing near the top thereof forming a passage directly beneath the top 3 of the casing, said passage communicating at its forward end with a space below the same and communicating with the outer air through openings l0 in the top 3 near the front of the oven. A flue or vertical tubular member extends within the oven adjacent to the back plate 1, 'said flue being open at its bottom to the space beneath the bottom plate 7 and communicating at its upper end with the passage between the plate 11 and the to'p 3 of the oven. A plurality of shelves 20, 22 are provided within the 'oven extendingA between the end walls thereof, kand being provided with perforations 21 for passage of hot air therethrough. Another shelf or partition 12 extends within the oven from end to end thereof substantially dividing the oven space into lower and upper chambers, this shelf being imperforate and extending suiciently close to the door to effectively retain the heat delivered into the oven. Said shelves slide on ledges 19 on the ends of the casing, and shelves 12 and 20 are provided with flanges 24; fitting around the flue 13 when the shelves are pushed in. The flue 13 is provided with outlets or openings 15 extending into the space beneath the imperforate shelf or partition 12 and with outlets or openings 16 extending into the space above said shelf or partition. Valves or dampers 17, 18 controlled respectively by handles 17', 18 being located above the respective sets of openings 15 and 16, so as to cause the hot air rising through the flue 13 to be deflected more or less into the respective spaces below and above the shelf 12 as may be required. A deflector 14, preferably formed as a curved plate, extends forwardly from the bottom of the flue 13 into the space beneath the bottom plate 7 to direct the hot gases or air arising from the heating means into said Hue.

In using the device, the lower compartment beneath the partition 12 can be used substantially independent of the spaces above said shelf, the lower compartment being used, for example, for baking and the upper compartment for broiling. At the same time the top of the oven can be used for cooking where bottom heat only is required. The plate 11 serves to confine the heat to the top of the oven, when the fiue valve 18 is open, to enable the top of the oven to be used for boiling, for example, while the inside of the oven is being used for baking. If it is desired, the openings 15 in the flue 13 may be closed by inverting the partit-ion 12 so that the flange 24 on the partition l2 covers the openings 15, thereby preventing heat from the ue entering into the space beneath the partition 12, in which case most of the heat from the lue 13 would pass out of the opening 16 in the iue to the space above the partition 12. The opening 16 in the flue 13 may also be closed by inverting the shelf 2O so that the flange 24 on the shelf 2O Would cover the opening 16 in the iue.

What We claim is:

1. An oven comprising a casing, a partition dividing the casing into a plurality of compartments and a flue for the heating agent formed with a plurality of outlets communicating with said compartments, said partition being adjustable and carrying means for varying the discharge of the heating agent through the respective outlets of said flue according to the various adjustments of said partition.

2. An oven comprising a casing, a partition dividing the casing into a plurality ot' compartments and a iiue for the heating agent formed with a plurality of outlets communicating with said compartments, said partition being adjustable and carrying means for varying the discharge of the heating agent through the respective out-- lets of said flue according to the various adjustments of said partition, and damper means in said iue above each of said outlets therein.

In testimony whereof, We have hereunto set our hands at Los Angeles, California, this 14th day of April, 1910.
