n HYDROCARBON-BURNER.

To all whom t may concern: Y

Be it-known that I, IVALTER E. IIUENE- FELD, a citizen of the'United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in IIydrocarbon-Burners; and I do lhereby declare the following lto be a full, clear, Vand exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesvto an improvement in hydrocarbon burners the object being to provide improved means for supporting and I'or lifting and lowering the combustion chamber member of the burner, and-it con sists `in the parts' and combination of parts, andin the details of construction as will be more fullyexplained and pointed out in the claims;

In the accompanyingdrawings, Figure 1 isr a view in elevation of a burner or stove embodying my invention; Figs. 2 and 3 are vviews inlsection, one showing the co1nbus. vtion chamber member lowered onto the wick tube member andthe other showing it eleva-ted; Fig.l4 is afview in perspective olil 4 is the wick tube member composed of4 two concentric tubes separated to form a wick chamber between them, the lower end of said chambergbeing closed and the upper i end open. v- The 'inner tube is open at both ends, and a nipple 5 isrsecured to the outer tubeffor connecting it with the oil supply pipe 2 in the usual manner, thenipple of course communicating with the wick chamber for supplying oil to the wick. The upper end of the outer wick tube is provided with an outwardly projecting flange 6 which is depressed somewhat Vforming a rib 7 'at the upper extremity of said tube. The inner tubeis provided with a depressedinwardly projecting flange S, the inner edge of which is bent;` downwardly as shown so as to providev an enlarged bearing for the combustion chamber elevating frame which will be hereinafter referred to. A wick 9 is located within'the wickchamber and 4is elevatedand Specification of Letters Patent.

for the lower venols of the perforated tubesrv 10 and 11, which are suitably spaced apart to form a` combustion chamber Vbetween them.

This combustion chamber-is located'directly over the wick, and is surrounded by the casing 12 which is spaced from the outer per- `orated tube 10, and is open at its upper end, its lower end being provided with an inwardly projecting perforated Hangs, which stops short of the outer tube 10," thusleaving an air space between them. This casing Y 12 is inthe form of aftruncatedcone' and forms a chimney to protect-,the combustionI chamber from draft. f

The upper end of the inner tube 11" of the combustion chamber member, `is closedl by a diaphragm 13 'having a 'central opening,

and its lower end is closediby a diaphragmY 1reaeieteu sept. '7, i915.y

14 havingk perforations near its outer` edge. i

These diaphragms, and Aparticularly rthe lower one 14, are pressed infso that the end f of the tube forms a marginal'flange within which the upper endofthe llifting'frame 15 rests. Y f l Located centrally within the wick tubev thatfthe wings form in 'electfa series ofV lues through which the air hasV free and unrestricted fpassage up through the wick tube member to the combustion chamber member of the-stove.

yThis frame isco'mposed of' a' In 4the Vpresent in-y stance the'frameis vcomposed of two V- f erably by welding, so vthat the two wings:

16`are ofV one thickness of metall andthe A other 17 of two thicknesses. `The frame thus formed lits snugly within ythe depending flangey 8 of the inner tube of the wick cham=A ber, and'is guided thereby, and' each wing 16 and 17 is-provided'vnearl its rlower endv with ,an integral outwardv eXtensiffri'nv18 adapted to bear.iagainstfthei'inner face'lof i the inner tube of the wick chamber and assist vin holding 'the frame 15 upright and guiding it in its vertical movements.

The two Vmembers constituting the wing 17, are each provided with a downward eX- tension 19, which are bent outwardly into inverted V-shape and form a 'saddle' 20, which normally rests on the oil supply pipe 2. This saddle is located centrally under the lifting frame preferably at right angles to the vertical axis of the latter, and the-l ends of its side members are rounded so that when the saddle which forms in effect a cam, is given a part rotation, it will ride up on pipe 2 and when in its highest position which is acquired by a quarter turn, it rests on and is supported by said pipe.

21 is a handle secured tothe saddle and projecting out beyond the wick tube member so as to be readily accessible for turning the lifting frame. The handle is preferably a wire rod bent to conform to the shape of the saddle, so as to brace the latter at the top and prevent any spreading of the two sides of said saddle. The lifting frame 15, when resting in its normal position on thev oil supply pipe, rests sufliciently well down within the wick. tube section of the burner, to permit the combustion chamber-member to rest on the wick tube member. When however the lifting frame 15 is turned; by the handle 21, its upper end engages the diaphragm 14: of the inner tube of the combustionV chamber member within the marginal flange on same, and elevates the said combustion chamber member sufriciently-to eXpose the wick whereby the latter may belighted. After the wick has been lighted, the frame 15 is turned so as to lower the combustion chamber member onto the wick tube member. g

-When the burner is not in use, the combustion chamber member may be elevated and held so by the frame 15, thus preventing the oil from working upwardly by capillary attraction from the wick, onto the tubesrof the combustion chamber member and thus avoid to a large extent the odor of the oil and also obviate the smoke resultingvfrom the combustion of oil on the tubes.

Instead of providing the wings with an outward extension 18 as above described, to assist the depending flange 8 of the inner tube of the wick chamber in guiding and supporting the lifting frame inv itsv vertical position, I may so construct the win s 1a of the latter, that they bear against t e inner face of the inner tube of the wick chamber throughout theV greater part of the length of the vlatter as shown in Fig. 5. This construction facilitates the insertion of the lifting frame into the wick tube, whereas' in the previous construction the lifting frame has to be carefully guided so as to enter the upper Yend thereof within the saddle inverted V-shape as shown it may be inverted U-shape as at 2Ob in Fig. 6, and

instead of making this lower cam member either an inverted V or U it may consist of a. half saddle 20c as shown in Figs. 7 and 8, rounded at one -end as in Fig. -7 or a half saddle 20d beveled as in Fig. 8.

vIt is evident that many other slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact arrangement of parts shown and described, but n Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a hydrocarbon burner, the combination of a wick tube member, a combustion chamber member, a lifting frame located within the wick tube member and movable vertically for lifting the combustion chamber member, a cam member rigid with the lifting port below and independent of the wick tube member, and ahandle located below the wick tube member for rotating the cam member.
