STOVE.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed August 17, 1914. Serial No. 857,061.

To all whom it may concern.

Be it known that I, CHARLES Gr. Row- LETTE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Stoves, of which the following is a specification.

My present invention relates to stoves, and its objects are to provide a cooking stove in which the oven may be closed off from the other cooking operations, to form a hotair containing and retaining chamber capable of serving as a so-called tirelesscooker; and further, to provide such means for thus closing off the oven as will shut the passages to and from the oven and at the same time open a suitable outlet from the air-heating chamber and vice versa.

These, and other objects appearing hereinafter, are attained by, and the invention finds preferable embodiment in, the structure hereinafter described and illustrated by the accompanying drawings, in which Figure l is an elevation of a cooking stove, partly in vertical section, embodying my invention:

Fig. 2 is a like fragmentary view of the same, showing the oven dampers in another position:

Fig. 3 is a vertical section of the same parts, taken on line A-B of Fig. 2, the oven shelves being removed:

Fig. 4 is an enlarged detail view in perspective of one of the dampers; and

Fig. 5 is a fragmentary view, enlarged, of another damper and connected parts.

The stove, (designated generally 1), has an air-heating chamber indicated at 2 containing suitable heating apparatus, as gas burners of common cooking-stove construction, not shown. Various cooking operations, as frying, broiling, etc, may be effected in or over this chamber, as by removing the stove lid indicated at 3. An outlet 4 permits the passage of the heated air to the outside of the stove, as to the pipe 5. A hot-air flue or passage 6 leads from the air-heating chamber to the oven 7, which may be provided with suitable removable shelves 8. Through the vent 9 the air in the oven may pass to the outside of the stove as to the pipe 10.

I provide means for closing and opening the said outlet, flue and vent, so arranged as to close the due and vent and at the same time open the outlet; and in another adjustment, to open the flue and vent and at the same time close the outlet. Preferably, these means comprise the damper 11 adapted to close the flue and the damper l2 adapted to close the outlet: these may be formed practically of one piece as shown in Fig. 4, and are slidably operated in vertical guides 13 by long links 14 whose upper ends are pivoted to the crank arms 15 on the rock shaft 16 having the operating handle 17 The vent is closed by a damper or valve 18 operated by links 19 pivotally connected to the crank arm 20 on said rock-shaft.

The crank arms 15 and 20 are so arranged relatively to each other that when the handle is turned to open the outlet 4, (as shown in Fig. l) the flue 6 and vent 9 are closed, and when the handle is turned to close the outlet & (as shown in Fig. 2) the flue 6 and vent 9 are opened.

It will be seen that by this arrangement there is necessarily an open passage to the outside of the stove from the air-heating chamber and its gas burners at all times, whereby accumulation of leaking gas with accompanying dangers is obviated: also, that hot-air may be admitted to the oven, and then the passages to and from it may be closed, in which condition it serves as a fireless cooker; and at the same time other cooking operations, as frying, broiling, etc., may be going on.

Not confining myself to details of construction shown or described, I claim 1. In a stove, an air-heating chamber having an outlet to the outside of the stove, an oven having a vent to the outside of the stove, a hotair flue leading from said chamber to the oven, and means for closing the outlet and opening the flue and the vent and for opening the outlet and closing the flue and the vent.

2. In a stove, an air-heating chamber having an outlet to the outside of the stove, an

oven having a vent to the outside of the stove, In testimony whereof I have hereunto set a hot-air flue leadmg :trom sa1d chamber to my hand 1n presence of subscriblng wit- 10 the oven, a damper adapted to close sald nesses.
