GAS=STOVE.

SPECIFICATION iorming part of Letters Patent No. 387,666, dated August 14, 1888.

Application filed August 6, 1887. Serial No. 246,287. (No model.)

To all whom it may concern:

Be it known that I, PETER G. VAN WIE, a citizen of the United States, residing at Cleveland, county of Cuyahoga, and State of Ohio,

have invented certain new and useful Improvements in Gas-Stoves; and I do hereby declare the following to be a description of the same, and of the manner of constructing and using the invention in such full, clear, concise, and

[O exact terms as to enable any person skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, forming a part of the specication, the principle ofthe invention being herein explained4 and the best mode in which I have contemplated applying that -principle so as to distinguish iti-from other inventions.

My invention is that of a gasstove in the 2O burner of which I use means for the mixing of currents of gas and currents of air in the process of combustion. To this end I arrange a series of perforated gas-pipes alternately with a series of perforated air-pipes, and so 2 5 construct and connect them together that they co-operate with cach other when used. The perforations of the said connected series of pipes being substantially all in the same horizontal plane with each other, I have a substantially dat structure as the base-plate of my stove. The perforated face ofthe said plate I locate as the under side, so that the lirst issue of the llames is substantially vertically downward. The upper unperforatcd face of the base-plate forms a heating-top. I

also p rovide for the circulation of air between the walls of the stove and the walls of the lower oven,which latter walls I extend up nearly the whole height of the stove. Be-

tween the walls of the upper oven and the extended walls of the lower oven I form a iiuepassage for the products of combustion of the lower burner, and I also provide forv the admission of air near the base of the lower oven and causeit to circulate through said oven into theiiue about the upper oven.

Further details of my invention appear in what follows.

In the drawings, Figure l is a sectional elevation of the stove, the front being removed. Fig. 2 is a vertical central section of the stove on the dotted line of Fig. 1. Fig. 3 is a horizontal sectional view of the stove on the horizontal dotted line of Fig. l, the burner being shown in reverse plan. Fig. 4 is a transverse 55 vertical section of the burner, taken on the dotted line of Fig. 3. Fig. 5 is a detail section of the lower door and air inlet, taken on the dotted line of Fig. 2. Fig. 6 is a detail view of a portion of the air-outlet from the 6o oven. Fig. 7 'is a detail section ofthe gas-iulet pipe and sieve.

The walls A of my stove inclose the oven B. Between the back and side walls, A', of the latter and the back and side walls, A, an airspace is formed, and a similar air-space is formed between the bottoms, respectively, A A3 ofthe stove and oven.

The burner C properly denes the upward limit of the oven, but the front, side, and back 7o walls, A', of the same are extended upwardly to near the top AL of the stove, between which top and the top A5 of the oven is a continuation of the air-space. An air-inlet, a, is formed in the bottom A, through which the air enters, and passing up through the air-space between the stove and oven walls is emitted through the burner-openings a2 of the top A".

Horizontal openings a* are formed in the front and rear upper portion of the walls of 8o the stove, and into said openings and extending from one to the other is inserted the dirtpan a to catch the dirt falling from the burners P, Said burners being located intermediate of said dirt-pan and the top of the stove. 8':

Burner C is formed as a chamber, thelower u side of which is corrugated. The half-cylindrical crests C of the corrugations are provided with perforations or jet-orifices c. In the trenches C2, between the corrugations, are 9o placed air-pipes provided with similar jet-oritiees, e,sirnilarly located. Said pipes are closed at their inner ends and have their outer ends open and flush with one of the walls A, in which they rest and are slipped through half-rings c, that span said trenches at the extremities ol' the' corrugations,and are secured in place by means of the set-screws d. An upper plate, Csfis sccured to the lower corrugated plate by any suitable means, and intermediate of the two is roo formed the gas-space 6*, divided by partition d2 into two equal parts. The gas enters through gas-inlet pipes E, ilows to all the crests C ol' the series, and passes out of the jet-orifices e formed along the longitudinal surface of said crests. Said orilices c c' in crests C and pipes D, respectively, are placed somewhat close down near the line where the alternate crests and pipes most nearly approach each other, and they converge somewhat in diametric direction toward each other. The number ol 1o orifices in the air-pipes may tally in number with those in the crests, and said gas-orifices and air-oriiices are preferably located opposite to each other.

Pipes D are removable by removing setscrew d,and when in position are used to assist in sustainin g the burner C within the stove-frame as the said pipes pass through and rest in the wall ofthe oven B and the back of the stove, while the gas-inletpipe, connected at either side 2o with the burner, passes through and restsin the two side walls ofthe stove. lhe burner C, located transversely in a horizontal plane near the center of the stove, practically separates the interior of the stove into the upper and lower ovens, respectively, B B.

Hinged to brackets g, secured to the lower portion of the stovei`ront, is the door Cl opening into the lower oven. A longitudinal slot, g', parallel with the stoved'ront, is formed in 3o bracket g at the foot of door G. Through this opening air is admitted to the lower oven, B, and aids greatly in the proper cooking of food, particularly meats, which latter it prevents from becoming dry and chippy. The air then passes up around burner C, where it isjoined by the products ot' the combustion of the gas. rlhe combined product of the two thence passes into the space intermediate of the top, side, and back walls of the upper oven and the top 4o A5 and the extended walls A 4of the lower oven, B. rFliese heated gases naturally rise and pass through the opening iz, formed in the center of the top A5, into the pipe h that covers said opening. Said pipe extends backward along said top A5, and thence downward between the back walls, A A', and discharges through the outlet la formed in the upper part ofthe back oi' the stove. Thus I have a continuous circulation of hot air on all sides except the front of my upper oven, and by n1aking the outletopening 7L above the center of the top of the oven B compel the heated air coming up the sides to pass over the top in every direction to said outlet. A door, J, is

5 5 hinged to bracket j at the front of the upper oven and affords access to it.

Across the opening of thc gas-inlet pipes E, I place a separator formed of a piece of tin, k, having many small openings or perforations,

6o like a sieve. This is for the purpose of preventing a ilame, when I light the burner, from tiring or kicking back up into the gaspipc.
