SPECIFICATION forming part of Letters Patent No. 739,143, dated September 15, 1903. Application filed January 31 1903. Serial No. 141,292. (No model.)

T0 at whom it may concern:

Be it known that LJACOB L. BERGE, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Improvements in Oil-Stoves, of which the following is a full, clear, and exact description.

This invention relates to certain novel and useful improvements in oil-burning stoves.

I have particularly in View as an object the provision of a stove which shall have an oiltank arranged compactly therein and a chamber or casing arranged above the tank and provided with apertures or passages to allow air to pass through said chamber, such air being heated in its passage.

A further object of the invention is to provide an improved arrangement of conduct: ing tubes or ducts for carrying ofi the products of combustion from the burner.

A further object of the invention is to pro- 'vide a stove which will be exceedingly simple in its construction, one which may be manufactured and sold at but comparatively small cost and at the same time shall embody the essential features of cleanliness, safety, and convenience.

To the accomplishment of the above-recited objects and others of a similar nature in view my invention consists in the construction, combination, and arrangement of parts, as is described in this specification, delineated in the accompanying drawings, and set forth in the appended claims.

. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference-indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a stove embodying my improvement. Fig. 2 is a central vertical sectional View taken through the same on the line 2 2 of Fig. 3. Fig. 3 is a transverse sectionalview taken on the line 3 3 of Fig. 2, and Fig. 4 is an enlarged detail vertical sectional view of the burner portion proper of the lamp.

Referring now to the accompanying drawings, 1 designates the base portion or housing of the stove, which is adapted to be elevated 1 slightly from the floor and supported bya suitable number of legs 2. Of slightly less diameterin cross-section and arranged in the aforesaid housing 1 is the chamber 3, adapted to contain fuel, which preferably consists of oil or a suitable hydrocarbon liquid, as shown at A. The bottom portion of the base housing or chamber, which also forms the bottom of the oil-chamber, is apertured to permit the passage of the air-pipe 4, provided with a controlling-valve 5. Thispipe is of preferably elbow form-that is, has a horizontally-extended portionand is bent to extend vertically upward through the oil-chamber, as at 6. Mounted above the portion 6 of the tube is a perforated cap 7, having a relatively large flat plate 8, covering the same. Spaced apart from each other below the plate are a number of annular flanges or rings 9, which act as deflectors or flame-regulators,'the lowermost of said rings being adapted when the cap is turned to act as a wick-cleaner. The rotation of this cap is accomplished by means of a spindle 10, which extends vertically upward from the elbow of the air-tube and through the cap, the lower portion of said spindle 10 being provided with interrneshing gearing 11, whereby it is connected with a rod 12, extending out through the air-tube near the base portion of the stove and provided at its end with a thumb-wheel 13. It will therefore be seen that when the rod 12 is rotated or turned the vertical intermeshing geared spindle will also be revolved, and the cap being rigid with the spindle will revolve. The wick (shown at B) extends around the air-tube and is in turn surrounded by a wick-supporting tube 14:. To the side of this wick-tube is secured a serrated bar or rack 15, which intermeshes with a pinion 16, rigid with the inner end of a turning rod 17, said rod having athumb-wheel 18'at its outer end. As will be seen,'especially by reference to Fig. 2, this rod extends through a frusto-conical plate-like portion 19, which acts as a diaphragm and divides the portion of the stove containing the oil-chamber from the upper or casing portion thereof, said platelike diaphragm having a flange 20, formed circumferentially thereof, which acts as a hearing or seat for the main casing 21 of the stove. The top of the oil-chamber, which is shown at 22, is also slightly convexedin shape, and at its apexor center is provided with a backwardly-turned head or rim 23, adapted to interlock with the inwardly extending shoulder 24: of a collar 25, the upper shoulder 26 of said collar being screw-threaded to the" outer surface of the thimble 27, the side 28 of said thimble bearing against the wickholding tube 14. As will be observed in Figs. 2 and 4, this thimble is provided with rows of circumferentially-arranged apertures 29.

The upper portion of the stove comprises the casing 21, mounted upon the shoulder 20 of the diaphragm 19, the said casing being provided with a cover of any suitable character, such as shown at 30. Arranged within the body portion of the casing are a number of approximately parallel vertical tubes 31, which are incased between the outer wall 21 and an inner wall 32, arranged so that a space of sufficient size to accommodate the tubes 31 extends circumferentially between the inner and outer walls. The height of the inner wall is less than that of the outer wall of the casing, and the top portion of said wall is provided with a flange 33, which extends horizontally outward and abuts against the outer wall or casing. This portion 33 is provided with apertures for permitting the pipes to extend therethrough, and above the same I preferably arrange two partitions 34 and 35, approximately parallel and spaced apart, such partitions being also provided with apertures to permit the passage of the upper ends of the pipes or tubes 31. The upper and lower ends of these tubes 31 are open, and at the lower end of the casing a passageway 36 is formed, through which passage flow the products of combustion of the wick or burner, such products passing up through the vertical pipes 31 and out through an opening 37, arranged in the outer wall of the easing between the cover and the upper partition 35.

At the back of the stove or casing I have arranged a number of air tubes or ducts 38, which communicate, as at 39, with the space formed between the partitions 34 and 35, and such air after being heated in its passage through the space between the partitions is allowed to escape at 40 into the room. I have also provided a row or a number of apertures 41 near the bottom of the casing 21, through which apertures air enters and being heated in its passage through the flueway by the pipes 31 then escapes in such heated condition through similar apertures 42, arranged near the upper end of said casing.

If desired, anysuitabie device, such as that shown at C, may be placed in the oil-tank for the purpose of indicating the amount of oil therein, an indicating arm or rod extending outward through the casing and having a pointer, as at D, at the end thereof.

From the above description, taken in connection with the accompanying drawings, the construction and operation of my improved burner or stove will be readily apparent. The wick being lighted, a suflicient amount of air is admitted through the main airtube and the section 6 thereof to the burner to enable the same to burn freely, and the products .of combustion from the wick or burner pass upward through the vertical pipes 31 and escape at the opening 37. In the meantime the air which is admitted through the tubes 38 and through the orifices 41 is heated and escapes in such heated condition into the room or apartment through the air-outlets 4.0 and 42. I

While I have shown and herein described one particular embodiment of my invention, it is of course to be understood that I do not limit myself to the precise details of construction, as modifications and variations in some respects may be made without departing from the principles of the invention or sacrificing any of theessential features thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A stove comprising a base-housing, an oil-chamber within said housing, air-conducting means extending through said oil-chamber, a burner mounted adjacent to the airconducting means, a casing mounted above the base-housing, tubes leading through said casing for conducting the products of combustion from the burner, and tubes arranged on the exterior of the casing for admitting air into said casing above the housing, and an outlet for the heated air from said chamber, substantially as set forth.
