STOVE.

Application filed Maldlt 27, 1224. Se1'ia1'No. 702,264.;

To all whom it may concern: 1

Be it known that I, Jnssn RTHoMAs, a citizen of the United States, residing at Kansas City, in. the countyv of lVyandotte andState of Kansas, have invented certain new and useful:Improvements in Stoves; and I do declare the followingto be -a full, clear, and exact-description of the invention, such-as willen-able others'skilled'in the art to which it appertains to make anduse the same, reference being had to the accompa-nys ing drawings,-and to the-figures of referonce marked thereon, whichform apart of this specification.

This invention 'relatesto stoves. It-is-primarily intended as a heatin'gstove although itis adapted to be used; as a cook stove. The primary object of the inventionis to provide a stove with an -o il.burner,.-the main body of the stove being in the form of a drum with verticaliflues. The stove. is-provided with a coal grate so that in the. event the oilsupply becomes exhausted, coal may be used, however I prefer-to utilize the oil burnerfor providing the necessary heat.

In the drawings,

. Fig. 1 is aperspectiveview of a stove constructed in accordance with my invention, part of the drum wall being broken away to illustrate the fines and part of the coal grate. V

Fig. 2 is a horizontal sectional view through the stove.

Fig. 3 is a horizontal sectional view through the oil burner, and

Fig. 4 is a perspective view of the oil burner, part of the vaporizing chamber being shown in section.

The drum 1 is of appropriate construction and it is provided with a door 2 at the front so that access may be had to the coal grate 3 and to the interior of the drum. Within the drum is a plurality of upstanding dues in staggered relation. The flue 4 immediately in rear of the grate is elongated transversely of the drum. It is connected to the bottom 5 in any appropriate manner and it opens to atmosphere at the bottom.

At the top of the flue 4 are two laterally diverging tubular branches 6 and 7 which communicate with atmosphere through the side of the drum 1. In rear of the flue 4 in spaced relation therewith and in spaced relation one with the other are two vertical fines 8 and 9, each having a lateral exten sion. The lateral extension 10 for flue 8 communicates with atmosphere through 1 one side ofthedrum 1 and the extension 11 for flue 9 communicates with through the opposite side of the drum 1 In rear of theflues 8 -and, 9 isa fine 12 corresponding with flue 4and itis provided with lateral extensions 13,and 14. likethe extensions 6. and? forlthefl-ue. 4 so the fines 4 and 12 may. betermed double fluesxi-while the ilues 8 and 9 are single; fines. The lines do not extend entirely to the top :plate15 of the stove but terminate shortthereof so that the products ofcombustion may flowaround and between the lines inatortirousmanner because the lines provide a tortuous passages Way. The products of combustion-cannot pass directly out through-the stove pipe opening 16 because there is a lateral baflle 17 over the. flue 12, consequently while the products of combustion may pass. around the flues 4, Sand 9 and over them as well-as they canpass around the..fiue 12,.butnot over it on accountofthe bafile- 17, thereforethe products of combustion will, effioiently heat the flue and the air within them. Since hot air has a tendency to rise; it: will be obvious thatsthe cold' incoming a-ir, assoon as it becomes heated in the. flue, will tend to rise and pass out through the extensions into the room. i I

The burner for, the stove is of.no-velcon struction. It is providedwith aCasingflS having air inlet openings-19 and 20 to support combustion. 'Within the casing 18 is a horizontal or substantially horizontal vaporizing; chamber 21 into which the oil may flow from a pipe 22 provided with a valve 22 so that the effective port area of the pipe 22 may be controlled. The vaporizing chamber 21 is provided with outwardly inclined sides 23 and 24 and an offset bottom portion 25 with inclined sides 26 and 27, inclined in opposite directions to the complementary sides of the main portion of the vaporizing chamber so as to provide triangular flame deflectors, spaced apart with the acute angles of the deflectors, substantially in line with the burner tips 28 and 29 controlled by the valves 30 and 31. The burner tips are supplied with fuel from a connection 32 communicating with the interior of the vaporizing chamber and with a manifold 33. The angles 34 and 35 of the deflectors are preferably not exactly in line atmosphere with the tips but they are so disposed that about two-thirds of the flame from the tip 28 will be directed 011 the outside of the deflector having the point 3e and about twothirds of the flame from tip 29 will be directed on the outside of the deflector having the point 35. One-third of the flame from each tip 28 and 29 will be directed inwardly so the deflectors divide the flame into three equal parts and since the deflectors are spaced apart, the flame will be spread over a relatively wide area, permitting the products of combustion to contact with the maximum part of the first flue 4t, and thus dis tributing the products of combustion throughout the tortuous passageway formed by the stagger-ed flues.

The combustion chamber may be con structed of heavy sheet metal or it may be cast if desired. A primer may be used to heat the manifold when the burner is first started, but after the burner is operating the flames from the tips or nozzles 28 and 29 will maintain the vaporizing chamber at sufficient temperature to vaporize the fuel and the air will be supplied through the ports 19 and 20. The lid 15 may be swung upon a hinge 36 of appropriate construction.

It will be apparent that the invention can be inexpensively construct-ed and that the tines and drum will afford a relatively large radiating surface so that the stove will ad mirably serve as a heating stove and while I prefer to operate the stove as an oil burning stove, using hydrocarbon fluid as the fuel itis obvious that coal or wood may be burned on the grate 3 if desired,

What- I claim and desire to secure by Let ters Patent is:

L A hydrocarbon burner comprising a hollow vaporizing chamber having a forwardly extending portion avith flat parallel walls and two offset depending wall portions having inclined sides spaced apart with the narrowest space at the rear of the chamber, means for feeding fuel into the chamber and nozzles immediately adjacent to the flat portion for directing flame against the inclined sides of the chamber.

2. An oil burner comprising a hollow vaporizing chamber having forwardly inclined sides and offset portions, said offset portions having rearwardly inclined sides to provide spaced triangular flame Spreaders, nozzles communicating with the chamber and mounted to direct flame against the spreaders and means for feeding liquid hydrocarbon fu-el into the vaporizing chamber.

3. A hydrocarbon burner comprising a hollow vaporizing chamber, the hollow vaporizing chamber being horizontally di posed and having depending triangular offset portions with apexes'of the angular portions directed toward the front of the chamber, the forward portion of the chamber extending beyond the apeXes and having spaced flat walls, nozzles for directing flame against the apeXes of the angular portions the angular portions beino; spaced apart, the inner walls of the angular portions con-verging toward the rear of the chamber so that the narrowest space between the walls of the angular portions will be at the rear of the chamber and means for communicating the nozzles with the chamber.

41. A hydrocarbon burner comprising a horizontal hollow vaporizing chamber having converging side walls the chamber ha ving triangular offset portions depending below the major portion of themhamber and burner nozzles in line with the. apexes of tie offset portions for directing flame a ainst said apexes and a pipe communicatin thenozzles with the vaporizing chamber.

In testimony whereof I alii): my signature.
