UNITED TATES JOHN H. SATTLER, OFSAN FRANCISCO, CALIFORNIA.
COMBINED COAL AND GAS STOVE.
Application filed August 7,
T aZZ whom it may concern Be it known that 1, Joan H. SATTLER, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a certain new and useful Combined Coal and Gas Stove, of which the following is a specification.
The invention relates to stoves which may be heated with gas or with coal or wood.
An object of the invention is to provide, in a stove of the class described, an oven which is efficiently and quickly heated either by the gas or by the coal fire.
Another object of the invention is to provide a stove in which the oven is quickly and uniformly heated by the gas fire.
A further object of the invention is to provide a stove of the class described, which is easily and quickly converted from a coal burner to a gas burner and vice versa.
The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description, where I shall outline in full, that form of the invention which I have selected for illustration in the drawings ac companying and formingpart of the present specification. In said drawings, 1 have shown one specific embodiment of my inven tion, but it is to be understood that I do not limit myself to such form, since the invention, as expressed'in the claims, maybe em. bodied in a plurality of forms.
Referring to said drawings:
Figure 1 is a vertical longitudinal section through the stove of my invention.
Fig.2 is a section taken on the line 2e 2, Fig. 1, one of the gas burners being omitted to disclose the air damper.
Fig. 3 is a section taken on the line 3-3, Fig. 1.
Fig. 4: 1s a section taken on the line 4l-4:, Fi 1.
The present invention relates particularly to the construction and arrangement of the oven, flues and gas burners within the stove, so that the oven is properly heated when either the gas or the coal fire is being used,
The heat for baking or roasting is applied differently when coal is burned than when gas is burned, and the stove is constructed to accommodate this difference. When .coal is used as fuel, the food in the oven is heated by radiation, since theproducts of combustion d0 notcomezinto contact with the food.
Specification of Letters Patent.
Patented Sept. 14, 1920.
1919. Serial N0. 315,847.
When gas is employed, the food is heated by direct contact with the products of combustion, which enter the oven. in accordance with my invention, I arrange gas burners in large combustion chambers disposed at opposite sides of the oven and freely open to the atmosphere, so that the gases of combustion are conducted directly into the oven. The burners are'arranged at the side of the oven, preventing overheating of the oven bottom, a' condition which causes food in the oven to burn on the bottom.
The stove of my invention is provided with a suitable fire bo1r2, provided with a grate 8, for the burning ofcoal, wood or other fuel. From the fire box, the products of combustion of the coal fire pass into the chamber or fine 4, formed between the top 5 of the stove and the top oven plate 6. From this chamber, the gases may pass directly into the upper part of the forward rear flue "4' which is sage of the gases being controlled by the damper 8, which when closed causes the gases to pass downward through the back rear flue 9, into the back bottom flue 12, formed between the bottom 13 of the stove and the bottom oven plate 14. The gases pass forward in the bark bottom line 12, pass around the end of the partition wall'15, which separates the forward fines from the back fines, and pass rearwardly in the forward bottom flue 16, into the forward rear fine 7, whence they pass into the chimney. The gases of combustion, therefore, pass across the top, across the rear and across the bottom. of the oven. The rear fines are forniedbetween the rear oven plate 17 and the rear wall 18. The oven is closed at the front, by the front oven plate 21, and at the back by the back ovenplate 22, both of connected directly to the chimney, this paswhich plates extend from the top oven plate Disposed within the oven at the sides thereof and spaced from the front and back plates 2122, are apertured inner plates 27-28,
which are alined with or form extensions of the side plates 23-24, so that the passages 25-26 extend upwardly to the top of the oven. The plates 27-28. are each provided with an aperture 31 disposed at the bottom of the oven, an aperture disposed midway of the height of the oven and an aperture 33 disposed at the top of the oven.
Arranged within the passages 25 and 26 and disposed opposite the bottom apertures 31, are gas burners 35 which are con nected across the of the oven.
The burners are disposed to direct the gas flames against the plates El -28 immediately above the bottom apertures. The gases of combustion of "he gas the enter the oven through all the apertures in the plat 2T 28 causing an equal distribution of heat throughout the oven. The air for the ombustion of the enters the passages 25 and 26 through apertures 36 in the bottom 13. These apertures are controlled by dampers 3T38, having apertures and cross bars so that longitudinal movement of the dampers opens or closes the apertures 36. The dampers are connected together at the rear by the cros lever 39 which is pivoted at its center to the stove bottom 18, so that the dampers mo; e together. li hen the coal fire is used, t 1e dampers are closed, and when the gas tire is used the dampers are opened.
The of combus ion of the gas fire discharge -roin the oven through a plurality of a1 ertures formed in the rear oven plate 17 adjacent the bottom of the oven and pass into the rear lines 7 and 9. By discharging these gases rem the bottom of the even, a complete ciiulation of the gases through the oven, before their discharge, is insured.
