1 To all it may concern:

Be itknown that we, WILLIAM HAILEs and JAMES GRAY,.both of the city and county of Albanyand State of New York,have invented certain new and ,jusefnl Improvements in Goal? Oil Stoves, which improvements are fully set forth in the following specification and accompanying drawings in five sheets, in which A Figure 1 represents aperspectivei view of a coal-oil stoveembodying the improvements n1 this invention, and adapted for cooking purposes. Fig. 2 is aperspectiveview of the same, illustrating{ the combustion-chamber section turned over from the base. Fig. 3 is a perspectiveview ofthe same adapted for heating purposes. Fig. 4' is a sectional elevation taken from side to side. Fig. 5 is" a secthe wick-tubesi Fig. 9 isa horizontal sectional view'taken 'through the combustion-chamber B, Figs. land 5. Fig-10 is a plan viewof the cookingsection. Fig. 11 is 'afs'ectionalelevation of the stove adapted for heating purposes. Figs. 12, 13, and 1 4. are horiz ontalsectional views taken through the combustionj chamber 13, Figs. 4, 5, and 11, illustrating I modifications of theform of construction of the combustion-chamber section that may be employed 5" and Fig. 15 is a plan viewof a duplex stove made with the improvements in by which oil may be supplied, to the wicks in a uniform manner without danger of explosion" of gases, the wicks be held in separate chambers free fromentanglement with each other, the flames be made to burn in separate "chambers, and the hot'products of combustion be conducted directly against thebottom or bottoms of thevessels placed on the stove,

and made to move outward incontact with said bottom or bottoms without the outer atmosphere affecting the} said hot products of combustion in the least. 7

In the drawings, A represents the base of the stove, to which is hinged, by hinge M, the combustion chamber B and its adjunctive parts. They are supported from the said base by several projecting pieces, a a, cast solid with said base. An air-passage, a, is thus made between the combustion-chamber and base, through which the air may pass or circulate, as indicated by arrow 1 in Figs. 4 and 5.

O is the cooking-chamber section, and D is the heating-section, intended to be employed with the combustion-chamber section for heating purposes when said cooking-section is not employed, the said two sections being intended to be used interchangeably with each other, as may be required. 1 Made continuous with the base A, and located at the rear side of the same, is the oilreservoir E, provided with a tight cover, I), having a flanged opening, b, through which oil is introduced to supply said reservoir. The said opening is closed by a stopper, I).

Made in the bottom of the reservoir E is a sub-reservoir, E, having a small extension in a horizontal direction, and with a depth below the reservoir E sufficient to bring the bottom of said sub-reservoir on a plane with the bottoms of the wick-chambers c c 0, located centrally within the base-section.

' A supply-tube, F, connects the said sub reservoir with said wick-chambers, and coneach other at their bottoms, so as to lead the oil supplied by the supply-tube F from one chamher to another.

Communicating with the wick-chambers c c c is the air-chamber 6, Figs. 4, 5, and 6, which air-chamber commences near the bottoms of the wick-chambers and extends upward to about the same plane with the upper ends of said wick-chambers.

The wick-chambers and connecting air-chamher are produced by means of the reversed angular plate z z sitting within the reversed angular plate as w, as shown in Figs. 4, 5, and 6. The said two plates thus forming the air and wick chambers are made gas-tight at their lines of connection by a rubber ball, e central fdr raising and lowering wic'ks of oil-lamps. a little below the uppenefidpf the wick tu'bes 'd d is the perforated diaphragm Gr, "ran er a saucer shape, withifts outer-sides or [rim inclined, as show'nin Figs. 4 aiid 5. 'Abo've the'diaphragin G is the solid or iinperi'drated plate H, provided with'a'rchesor caps d il','having slots h it directly over the ends of the wick-tubes d d, through which slo'ts the names tur The "combustion-chamber B, in whieh the "fiairies of the several wicks burn,-maybei1'iade "or metal,"ormetal' set with mica 'or'glass'g, 'or

In theup'per portion of the walls of the air-chamber are made a series of openings an, through which the air heated 'in the"air eliaihber Iliay escape into the combustion or flame chamber at a point slightly below the exits, N I

When the cooking-section is not einployed, and it is desirable to employ the stove for warming purposes, the heating-section D is to be placed over the combustion-chamber sec- .tion, the cooking-section first being renrove'd. The said heating-section a! p composed of I an outer annular chamber,pggapdg centrahaia chamber, -.D made g ontinuo uswith tlie"airam At heh s'q isthe ea e e ber-Dare madeta series of smaIl'ope'nings, r 'r, throughjwhich air;

,It may bereadily, seen that, bythe arrangement of the air-chamber Q with thewi ck-chambers and their supply pipeiand oilfreservoir, the air in said hange]; villppreventi the 'oil rising up o a ne w h the tempt the! sa wick-chamber, whileat the same tjmcjt will operate to press back on the oilfin the reservoir through the supplytpbgand thereby exert on the oilin the wick-chambers a degree o 'p a p su di att the w ght of the oil in the reservoir. By orming thesaid wick-chambers and an;

means of a single bolt, makings e and 0 between, the saidpl'atesmay be readily separated to expose theirinner surfacesfor cleaning or pn pbses, }l /?'Xl .1. '1l f It mayalso be readily seen that by divid ng the combustion-chamber-section by'the vertical walls 70 70 each flame Quay hav e its own chamber to burn in, wh le said'plat'elzs will at the same timeoperaite" prevent any excessive diversion of heat from a passage through the exits above.

To prevent the, wickgcli'afiibers: becdriiing chamber of the plates wall-surfacea'ajiduniting the gem platesfiby r 1 .By reason of the attachment to the cookingsection of the horizontal flues G radial from "the exits 0 and having the vertical intermethe same, in which case the bottom of the vessel will form, in fact, the top. plates of said flues, while at the same time the air of the room will be prevented from mingling with the hot gases until they have been made to' pass the full distance or length of said flues, )7 in contact with the bottom of the vessel thereon. A v

It may also be readily seen that, by the heating-section being composed of an outer and inner chamber, witha tapering form of divid-' in gwall between, and provided with the openings above described, the air entering within said chambers will become highly heated by reason of the heating of the tapering dividingvwall, which will cause said wall to act as a radiator, to heat the air moving upward through said chambers, which air will, when heated, escape. into the room.

- Another advantage is that the air of the room will be kept in circulation by the heated air being continuously replaced by fresh cool air,

Having described our invention, we claim- 1. The combination, with the oil-reservoir E, supply-pipe F, and wick-chambers c c c, of

the air-chamber e, communicating with said 7 wick-chambers near the bottom of the. same,

substantially as and for the purpose set'forth. 2. The combination of plates at and 2, each havingthe form shown and described, with the rubber packings e and 0, bolt f, and nut f, substantially as and for the purpose set forth.

3. The combination, with the combustionchamber section and burners, of Vertical partition-plates k is, arranged polygonally, and separating an inner air-chamber from the flame-chambers, substantially as set forth.

4. In an oil-stove, the combination, with the combustion-chamber section, of the cookingsection 0, having radial horizontal lines G? 0 leading outward from exits 0 O and separated from each other by the intermediate vertical walls 0 0 when all are arranged to adapt said horizontal flues tolead the hot gaseous products from the said exits outward and in contact with the bottom of a vessel placed over the same, substantially as and for the purpose set forth.

5. The combination, with the combustionchamber section and a central air-chamber receiving air from beneath, of the heating-chamber, composed of an air-ch amber provided with vent-openings above, and inclosed by an outer chamber situated vertically over the said combustion-chamber section, said outer chamber being provided with openings at its base, and havinga tapering form of dividing-wall between said outer chamber and said heatingchamber, all arranged and constructed in the manner and for the purpose set forth.
