OIL-STOVE.

Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed January 3, 1919, Serial No. 269,398. Renewed July 19,1920. Serial No. 397,550,

T 0 all whom it may concern:

Be it known that I, FRED E. WHITE, a citizen of the United States, and resident of Gardner, Massachusetts, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

My present invention relates to improvements in oil stoves and more particularly to stoves of the lamp or wick type.

The invention aims to provide a construction which will be economical to manufacture, being strong and durable in use, and

which will provide a maximum of radiating surface.

The invention further aims to provide improved means for keeping the oil tank or font and burner tubes from overheating.

With these and other objects in view the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims, an embodiment of my invention being illus trated in the accompanying drawings, in which,

Figure 1 is a side elevation partly in section of a stove constructed in accordance with my invention.

Fig. 2 is a similar view of a modification.

Referring by reference characters to this drawing, the numeral 1 designates the stove base provided with legs 2 and containing the fuel reservoir or font 3, having a burner i, all of which parts may be of the ordinary' or any desired construction.

5 indicates the drum base which may be connected with the stove base 1 in any suitable manner, as by being hinged thereto at one side, as shown at 5 and provided with a suitable spring catch 5* diametrically opposite thereto.

6 designates the drum which is preferably made in two parts 6 and 6, having their edges connected by spinnin the edge of one over an outwardly turne flange on the other, as indicated at b.

The upper part 6 may be rovided with the usual perforations as indicated at a. The lower part of the drum is formed cylindrical for a portion .of its height and is then tapered or contracted, as indicated at 6,

tending flanges, which are clamped together by the overturned edge of the perforated collar 7.

Inorder to protect the wick tube and underlying portion of the font from the flame I provide an inclined screen 8, preferably of perforated sheet metal, which extends from the top, or close to the top, of

the outer wick tube, downwardly and outwardly to the lower edge of the collar 7, and on; which the lower edge of the latter normally rests.

ll Ieans are provided for admitting air beneath the drum base, such for example as the annular perforations 9 and other perforations are Provided in the upper contracted portion of the drum base, as indicated at 9. Air flows inwardly through the perforations 9 over the u per surface of the font or reservoir and serves to keep the latter cool, the inner portion around the burner tubes being further protected from the radiated heat by the perforated shield 8. Part of the air admitted through perforations 9 passes upwardly through perforations in shield 8 to support combustion, and the balance escapes through the openings 9', direct to the atmosphere in the annular open channel between the lower part of the drum and the drum base.

By making this annular space entirel open to the atmosphere I provide for the direct outward radiation of heat from the hot surfaces of the tapered portions of the drum and drum base. 1

Instead of forming the lower portion of the drum of inverted frnsto-conical form and the corresponding portion ofjthejdrum base of frusto-conical form, there'b'yl providing an annular channel of substantially wedge shape cross-section, as in Figl", I may, as shown in Fig. 2, extend these portions of the drum and drum base inwardly in substantially parallel but spaced relation, as indicated at 6 and 9" in Fig. 2, in which event the inner edges of the walls 6 and 9 may be curved or bent toward each other and merge into flanges clamped together by the overturned edge of the perforated collar 7 in the same manner as in Fig. 1.

Additional supporting means for the drum may .be provided if desired in the form of struts or supports 10 interposed between the parts 6 and 9" near the outer edges thereof.

It will be obvious that the walls 6 and 9 may be spaced any desired distance apart to secure the channel of the desired size.

Having thus described my invention what I claim 1s:

1. In an oil stove a font having a burner, a drum base overlying the font and extending inwardly toward the burner and a drum having a cylindrical portion and an in wardly extending portion meeting the in- Wardly extending portion of the, drum base, said inwardly extended portions of the 1,see,eea

drum and drum base providing a completely open interior annular channel and an open exterior groove.

2. In an oil stove a font having a wick tube projecting upwardly therefrom, a perforated shield extending outwardly and downwardly from the upper edge of the wick tube, a drum base having a conical portion extending inward over said shield, a drum having a contracted lower portion connected to the edge of said conical portion, and a collar connected at its upper edge to the meeting edges of the drum and drum base and having its lower edge resting on the outer edge of the shield.

In testimony whereof, I afiix my signature.

FRED E. WHITE.
