Specification of Letters Patent.

Patented Aug. 199, 19113.

Application. filed (Ectober 10, 191.2. Serial No. 724,9?2.

T 0 all whom t may concern:

Be it known that l, )VAI/ran E. Huarternnn, a citizen of the United States, residing wat Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the Jfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

This invention relates to improvements in hydrocarbon burners and particularly to such as are adapted for use with oil stoves,- the object of my present invention being to so construct the device as to keep the inner wick tube cool and reduce to a minimum thel undesirable effect of sudden drafts of air, upon the flame on the wick.

)Vith this and other objects in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims. l

ln the accompanying drawings, Figure 1 is-a sectional. View of the device with the parts in their normal operative positions.

to cooperate with. suitable raising and lowering means. T he outer wick tube is provided at its upper end with an outwardly project ing depressed flange or seat 7, and theinner wick tube is provided at its upper end with an inwardly7 projecting flange 8, from the inner edge of. which7 a ring 9 projects upwardly. From the upper edge of said ring, ,an annular fiange or seat 10 projects inwardly and may be provided at its inner edge with a depending rib 11.

The combustion. chamber member 2 compriseswconcentric foraminated shells 12f-13 spaced from each other to form a combustion chamber 14 between them, whichis in line with the wick. The shells are inclosed by a casing 15 which is spaced from the outer shell 13 and is open at its upper end, the lower end of said .casing being provided with an inwardly projecting perforated Harige 16. The shells 12-13 and casing 15 are secured together by means of crossrods 17. i

4The lower end of the shell 13is seated (when the parts are in their normal working positions) upon the outer depressed flange or seat 7 at the upper end of the wick tube 3. The inner foraminated shell 12 is provided :1t-.its upper end with a perforated cap 18 and at its lower end (which termi-. nates a short distance above the horizontal plane of the lower end of the shell 13) is provided with a perforated cap 19 which rests (near its peripheral portion) upon the seat 10 at the upper end of the inner wick tube 4. Thus it will be seen that the foraminated shells of the combustion chamber member are supported respectively, upon the seats 7 and 10 of the wick tubemember, with the combustion chamber le immediately over and in direct alinement with the wick, and that the weight of the parts will in' sure the firm seating of said foraminated shells.

The lower cap 19 is construct-ed with an annular series of radial lugs or fingers 20 and the lower end of the shell 12 is notched to accommodate said lugs or fingers,--the4 lugs 21 formed by thus notching the lower end ot the shell being bent under the edge of the cap 19 and serving to retain the latter in place. The lugs or lingers 20 enter the combustion chamber 14 and project a sufficient distance across the lower portion of the same to be in line with the wick and constitute limiting means for the latter. From this construction, it will be observed that the wick limiting lugs or fingers are made integral with the lower cap of the inner shelll 12 and that said lugs or fingers are therefore vertically movable with the combustion chamber member away from and toward the wick, but that when the burner is in operation, said limiting. devices may be in more or less proximity to the wick (according to 4the adjustment of the latter) without detracting .from the eii'iciency of the flame on the wick.

A tube 22 is secured at its upper end to the lower cap 19 and, projecting downwardly through the opening formed by the rality of holes 22a, and below said holes, a diaphragm 22b is fixed wit-hin said tube. With such construction, drafts of air directly through the tube will be prevented by the diaphragm 22h, the air entering the lower end of the` wick tube member being compelled -to pass upwardly through the space between tho inner wick tube 4t 'and the tube 22 and plose' to said inner wick tube; through the holes 22a1and then upwardly through the perforated cap 19 into the inner ,shell of the combustion chamber member. With such construction, the inner wick tube will be kept cool and undesirable effects upon the flame by sudden draftslof air will be reduced to a minimum, the passage ofA air through the burner being retarded and kept practically uniform. p

The tube 22 constitutes a guide for the vertical movements of the combustion cham- `ber member, when the latter is raised or lowered by means of devices such as will now be described.

A ring 23 is located within the'cylindrical space formed by the inner wick tube and is provided with .arms 24 rigidly secured in any suitable manner to the interior ofthe indiagonal edge, a horizontal seat 28 is formed and at one end of the lattei', a lug 29 projects upwardly so as to form a stop shoulder 30. At the side of `each arm 25 opposite the diagonal or inclined edge thereof, a horizontal slot 3l is formed,-the lower wall `of the horizontal slot in one arm `forming, in elliect, a continuation of the inclined oi.' diagonal edge of the adjacent arm but at an angle to said edge.

When the combustion chamber member is in its normal operative position, the inwardl projecting pins 26 of the guide tube 22 wil be disposed in the horizontal elon l gated slots 3l of the arms 24 and said combustion chamber member will be locked in its lower operative position. l/Vhen it is desired to raise the combustion chamber member above the wick tube member, the operator will turn said combustion chamber meinber in one direction so as to cause the pins 26 to ride on the inclined edges 27 of the arms 25. When the pins 26 shall have reached the upper ends of said inclined edges, a fur ther turning movement or' the guide tube will cause said pins'to become disposed upon 'chamber member will be sutlicien't to cause said pins to ride down the inclined edges and enter the elongated slots bl, thus causing the coinbustion chamber member to beco-ine disposed in operative position on the wick tube member and to be locked in such position.

lVhile I have shown and described the manner of supporting the combustion chamv bei' member on the wick tube member, and also wick limiting means, l do not herein claim these features speciically,-the same constituting the subject matter of my co'- operating application Serial No. 724,971.

Having fully described my invention what I claim as new and desire t0 secure by Letters Patent, is:

l. In a hydrocarbony burner, the combination with a wick-tube member, and a combustion chamber memberhaving a perfol rated bottom cap, of a tube secured to said bottom 'ap and movable in and guided by said wick tube member, said tube having holes below its upper end, and a diaphragm within said tube below the plane of said holes, the wall of saidl tube below the plane of said. diaphragm being in'iperforate.

2. In a hydrocarbon burner, thel combination with a wick tube member, and a. coinhustion chamber member provided with a perforated bottom cap, of a tube open at both ends and provided with holes near its upper end, said tube secured to said bottom cap and entering and guided by the wick tube i'neinber, a. diaphragm within said tube below the plane of said holes, and raisingv and lowering devices secured within the wick tube member, said raising and lower-l ing devices entering said tube and coperating therewith to raise or lower the combustion chamber member when the latter is turned.

[n testimony whereof, l have signed this specification in the presenceof two subscribing witnesses.
