JAMES w. ASHBAUGH, or BREMEN, oHIo.

Gas-HEATER. a

Application `filed January-5, 1918. ASerial No. 210,425.

. To all whom it may concern:

' so that it will be in a heated condition when Be it known that I, JAMES W. ASHBAUGH,

a citizen of the United States, residing at Bremen, in the county of Fairfield and State of Ohio, have invented certain new and useful'lmprovements in Gas-Heaters, of which the following is a specification.

This invention relates to gas stoves or heaters, and has for its object to provide a stove of this character embodying improved features of construction which will enable the same to radiate or give off a maximum degree or quantity of heat in proportion to the amount of fuel consumed.

Another object of the invention resides in a gas stove wherein is provided means for effecting av continuous circulation of air therethrough, and which air, during its natural circulation through the stove, will be brought into Contact with vheated surfaces ejected or radiated from said stove. A further object is to provide a gas stove with'novel features of construction for allowing the gas fumes of its burner to pass off from the stove without enteringv4 the ini mediate'atmospliere, said construction being located adjacentV to the upper end vof the stove and formed to surround the means for sageway 10, the-latter being in communicapermitting of a circulation of air through the latter.

Y note corresponding Other objects will be in part obvious and in part pointed out hereinafter.

For a further disclosure of the invention, reference is to be had tothe following description and lto the accompanying drawing, forming a part of this specification, and in which Vsimilar characters of reference departs throughout the several views thereof.

In the drawing:

stove comprising the present invention.

Fig. 2 is a vertical sectional view thereof,

taken along the line 2-2 of Fig. l.

Fig. 3 is a horizontal sectional view taken along the line 3 3 of Fig. 1, and disclosing more particularly the fume exhaust passagewav.

4 is a fragmentary horizontal sec- Y tional view taken substantially along the line 4-4 of Fig. 1. Y

Referring more particularly to the drawing, the stove in its preferred form consists of a sheet metal structure and includes a rectangular backwall or plate'l, to the lower Specification of Letters Patent.

end of which is suitably connected a semicircular base band 2, these members l and i 2 being preferably equipped with a suitable number of supporting legs 3, whereby the stovebody may be positioned in spaced relation from a floor or supporting base. To

the upper edge of the band 2, there is selthe upper `extremity of a semi-circular hol.- Y low gas burner 5. The burner extends substantially from the base of the wall V1 toa plane above the reduced uppervend of the plate 4, and has its upper horizontal surface 6 provided with gas outletopenings?, andk in kwhich position-gas passing through the burner may be ignited. Fuel is intro-` duced into the lower extremity .of "the burner through the medium of a pipe 8,-the

latter extending in a horizontal direction and terminating in an outwardly protruding valv'ed extremity 9, by use of which the iiow of fuel through the burner may be conveniently governed. v

The body of the burner 5, as hereinloefore Y stated, is substantially semi-circular in cross.v section and'has theupper and lower ends thereof left open so as to define an air pasreduced end disposed vadjacent to the vupperhorizontal surface of the burner 5, and is exteriorly .provided with -a fibrous covering of abestos or the like, and serves to radiate the heat of the stove in the even andA constant manner common t0 gas stoves Figure 1 is a front elevation of the gas of this character. It' will be understood, however, that it is not necessary to construct and locate the `plates 4 and 12 in the manner specifically set forth above.v and that such plates merely provide asubstantially semispool shaped heat radiating structure, in which the burner 5 is centrally positioned.

The open and upper relatively widened extremity of the plate 12 isV connected in any suitable manner ywith a curved toplwall 13 secured to the upper extremityv of the wall 1, and the wall 13 is provided with a vertical downwardly disposed flange 14, the latter surrounding the `upper end of the plate 12. Forming the backwall of the passage ,l

way 11 is an inclined Vplate 15, which is spaced'from the wall 1 to define an exhaust,

extremity of the plate12. By virtue, of this construction, it will be manifest that the gas fumes arising from the burnerv 5, will collect within the channel 17, which being in comloununication with said exhaust chamber, will Vpermit the fumes or exhaust gases to flow into said chamber, whence the same pass off from the'stove by way of outlet means 18. This construction effectively prevents the v15 obnoxious s gases or fumes from intermin- -gling with the atmosphere of the room in whichY the'stove is situated.

At this juncture, attention is directed to `the air'passageways 10 and 11, which are 2odesigned to increase the heating efficiency of --t'he stove. lt will be observed that air passing through VAsaid passageways will be subjected to the heat radiated inwardly from he 'plates'll and 12 vand will thus be in a heated condition when the same is passed off. into the atmosphere byVA way 'of the openings 19, formed in a removable lid member 20. Thus a positive circulation of air through said passageway will bemaintained bythe effect ofthe arising heated air in the Y upper passageway 11, and which air is finally utilized in heating the atmosphere surrounding the stove. If desired, a semi-circular guard member 21 may be carried by 9,5l thel upper curved extremity of the stove, in VVorder to enhance the ornamental appearance of the latter and to preventone from un- Y duly contacting with the heated surfaces ad- `jacent thereto. VAlso to prevent further ini0 jurious-contact with'the heat impartingsur- Y faces 4, 5 and 12, use is made of a wire'mesh screen or the like 21', which is adapted to inclose the entire open front of the stove, thus rendering it impossible for one to vcome accidentally into engagement with said surfaces. The screen 21 may be hingedly mounted, if desired, to the flange 14 so that Y f the burner 5 may be readily accessible by simply' elevating said screen;

From the foregoing it will be seen that the stove is' so constructed that an im- Vfrom the stove where they may be remotely discharged without contaminating the atmosphere of the room in which the stove is situated. And in connection with the above there is lprovidedthe means for circulating air through the stove and heating the same, so that the maximum amount of heat may be derived lfrom the stove in proportion to the quantity of fuel consumed and in conclusion the stove fis equipped with improved means for preventing unwary persons from being burned by the heating surfaces of the stove, and to otherwise generally safeguard the latter.

Having described the invention, what is claimed is: Y

A gas stove comprising a base, a rear ver tically extending wall forming apart of said base, a semicircular vertically situated burner member cooperative with said wall to form a verticallyV disposed air 'passageway extending substantially'throughout the height ofl said base, said burner member beingfprovided at its top witha rowof fuel discharging orifices and at its lower end with a valved fuel supplying connection, a lower semiconical heat reflecting plate carried by'- said base and having its apex situated immediately beneath thev orificed-portion of said burner member, said plate being )situated to substantially surround' said burner member, anv upper inverted seml- .conical heat' reflecting plate cooperatively carried bysaid walland spaced from said latter toy define anl air circulating passageway, the flower reduced end of said upper plate terminating in communication withsaid air passageway to the rear of" said burner member, whereby a continuousy air circulating space Vis provided-through said stove byy the formation of said burnerfmember and said upper plate.V l Y In testimony whereof I c fliX my signature in prese-nce of -two witnesses.A 1
