GAS STOVE.
Application and October 1, 1923. Serial No. 665,918.
T all whom it may concern:
Be it known that 1, JAMES G. Soon, a citizen of the United States, residing at Washington, in the, District of Columbia, 8 haveinvented certain new and useful Improvements in Gas Stoves, of which the following is a specificatiom I This invention relates to gas stoves, and
more particularly to gas stoves of the closed top type.
An object of the invention is the provision of means for maximum heat transfer to foods and solids cooked thereon at the same time maintaining perfect combuslb tion under Variations of pressure, specific gravity and heating values. ordinarily enhcountered throughout both natural and manufactured gas distributions.
A further object of the invention is the provision of an improved arrangement of burners and means whereby perfect carbureting of primary and secondary air supply to each burner used on said stove causes fan ultimate delivery to the stack or flue "of fiue' gases, the analysis of which shows less than a dangerous amount of carbon monoxide 'andmore than a safe amount of oxygen. v
A further object is the provision of means the cooking top burners for the purpose of cooking food in an oven without lighting the oven burner.. A further object is the provision of means whereby the products of combustion may i be passed, directly through the stack, or through the oven to the stack, without interfering' with the proper combustion of thefuel;
A further object is to provide an improved arrangement 'to supply secondary airto the lower oven of the stove which will prevent, chilling of the upper oven when the lower oven is not in use.
In the accompanying drawings, I have shownone embodiment of the invention. In this showing:
Figure 1 is a of a stove on a line beneath the top of the burner compartments,
, Figure 2 is a; vertical sectional view on line 2-2 of Figure 1, I
Figure?) is a vertical transverse sectional view on line 33 of Figure 2, p
for utilizing the surplus heat generated by .to the burners, whic horizontal sectional View Figure 4 is a detail perspective view of the flue through which the gases pass from theburner compartments to the stack,
Figure 5 is a horizontal sectional view on line 5-'-5 of Figure 4,
Figure 6 is a vertical line 66 of Figure 4, Figure 7 is a detail the bottom plate ofthe top oven, and,
Figure 8 is a detail sectional view of the door of the, lower oven on line 8-8 of Figure2. 1 I
Referring to the drawings, the reference numeral 1 designates generally the lower supporting structure of the stove which is of the usual type and will, therefore, not be described in d'et'aih It is provided with sectional view on perspective view of the usual legs-2, ada ted to rest upon the' floor. The burner s ction of the stove is provided with a removable top plate 3. having openings therein ada ted to be closed by stove lids 4. A partition 5 isarranged beneath the top plate forming an upper' compartment 6 and a lower compartment 7 This partition is provided with openings 8 and burners 9 are arranged in the lower compartment with the tops of the burners immediately beneath the partition 4., As shown, the openings; 8 are surrounded, by vertical flanges 10, forming stacks surrounding the burners, The lower compartment is closed at the bottom by means of a removable plate 11 of the usual construction, supported in suitable guides 12. This compartment is open at the front for the purpose of so plying secondary air the stacks formed by the flanges 10. A
air passes through manifold pipe 13 is supported in suitable brackets l t-oii the'front ofthe stove in. the usual manner and theburners are connected to the main feed pipes" by burner arms 15. A burner arm 16 is arranged adjacent the oven side5of the-stove and; is connected to a burner 17 iii the-lower oven. The flow of gasxthrough the burner arms is' controlled b 'meanso fcocks 18.
As shown, t e compartment'fi issubstam tially rectangular in shape and.}is ro'v'ided I and one larger-burner adjacent the 1 other side or the st vef-bThs'space at this side with ,two burners arranged" in "a moment transversely of thestbve. adjacent the'oven of this plate is shown in Figure 7 of the oat the compartmentby means ofa damper drawings. As shown, it consists of a pair of plates 29 and 30, slightly spaced from each other and connected by means of front and rear walls 31, theplates being separated at the sides to permit passage of .gas and heated air as shown in Figure 2 of the drawings. The upper plate 29 is provided with a plurality of openings 32 and permit the gases to pass upwardly into the central portion of the top oven. The side walls of the top oven are provided with passages 33 I through which the heated gases are adapted to flOW and these passages are provided with,
- When the oven is not being used and the damper.24 is in closed position to prevent the passage of gases through the oven, the gases from the compartment 6 are conveyed directly to the stack. As shown in Figures 4 to 6 of the drawings, I provide a flue 42 at the back of the. stove, which flue extends horizontally and is divided by means of a partition 43 into a pair of chambers 44 and 45. The rear chamber 45 is provided with an opening 46, communicating with the compartment .6 to one side of the damper19,
whereby this portion of the compartment may be connected directly'to the stack with the damper closed when the burners in the other portions of the compartment 6 are not in use. The chamber 45 communicates with the other portion of the compartment 6 through an opening 47. These two chambers in turn communicate with a passage 48 arranged behind the ovens which in turn communicate with the stack 41.
Heretofore, it has been customary to supply secondary air to the oven burner directly 'from the atmosphere and the difierence in tem erature between the interior vided with a like number of openings to permit uninterrupted flow of secondary, an: to the burner 17'. In the present construction,
however, I provide an inner wall with a reduced number of openings 53 so that only a small amount of air is drawn from the room while providing means for inspecting the flame. To supply the additional secondary air necessary for the operation. of
the burner 17, I provide an opening 54 in the side wall of the oven, 'communicatin with the compartment 7 beneath the partition 5 and thus supply preheated air to the oven. VVhen the lower oven is not being used, the air passing through it to the upper oven, is then at a much higher temperature.
The operation of the device will be apparent from the foregoing description.
tion, shown in Figure 2 of the drawings, the products of combustion in a heated state pass through the compartment 6 into the oven. It will be noted that the openings 46 and 47 to the flue are arranged level with the lower surface of this compartment and when the damper 24 is open, the natural tendency of heated gases to pass upwardly will cause the gases to flow into the top oven 22. This eliminates the necessity of a mechanically operated damper to close the openings 46 and 47 when the oven is being used. In the oven, the gases flow as indicated by the arrows, a portion of them passing between the plates 29 and 30, forming the bottom of the oven, to the passage 33 on the farside of the oven. Some'of the gases passing through this space flow through the openings 32 into the ,central portion of the oven. The gases inif'the two passages 33 flow into the oven through the openings 34 (and. thence to the top space 38 through the openings'37. It will be apparent that the provision of an insulated top formed by the sheet 39 will maintain a higher temperature in the oven, as loss of heat by scrubbing or radiation is reduced to a minimum. The flow of gases through the passage 38 when the insulation is not provided, constantly draws heat from the oven into the room through the top plate 35 which is formed of With the dampers 19- and 24 in open posilid metal and is therefore a good conductor of heat. When th space 38 is separated from the oven by in lation, practically the only heat lost is the heat of the gases in the passage 38 which have served their purpose and are on the way to the stack. 7 i
As stated, the openings 46 and 47 arrangedbeneath the compartment'ti, tend to retard the flow of gasesfrom the compartment to the stack and when the damper 24 is closed and these gases are being sent direct to the stack, they flow very slowly from the compartment 6, whereby maximum efficiency of heating is obtained. When the lower'oven is being used, the burner 17 is lighted and the gasesfrom-the lower oven pass upwardly through the top oven to the stack. By providing the opening 54, air is delivered to the lower oven in sufficient quantities to insure perfect, combustion and in a preheated condition. This is of material importance when the lower oven is not being use, as the flow of air from the lower oven to the upper oven caused by the flow of heated gases through the upper oven heretofore had a tendency to reduce the tem-.
peratu're of the upper oven 10 to.15 degrees. The construction of the cooking top of the stove has been designed to afford substantially complete combustion and not chill theburner flame. An analysis of the stack gases shows a-practical elimination of car-' bon monoxide, with a maximum temperature. This result is obtained by providing means for furnishing a balanced, uninterrupted flow'of secondary air to the burners. Air is fed to the'lower compartment at the front, and when the stove is operating, the fiowof gases causes a stacking effect, around each of the burners, causing the. air to flow upwardly within the flanges 10, through the burners by induced draft. The movement ofthe products of combustion toward the fines 44 and45, or toward the oven, draws additional air to each of the burners through the flanged openings, and this process is continuous as long as the stove is in use. By providing the two fines 44 and 45, theyolumetric proportion of the compartment 6 and the-flue may be better proportioned and when one half of the. stove is in use, the damper 19 may be closed. The partition 7, as stated, feeds'the secondary air'to each of the burners upwardly through the flanges 10, and this permits two or more burners to be arranged one behind the other,
which has heretofore been impossible in closed top gas stoves.
' It is tobe understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that'various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or' the scope of the subo1ned-cla1ms. Having thus described my invention, I
claim:
