EDWARD BOEKENKAMP, OF ST. LOUIS,

MISSOURI, ASSGNOR TO AMERICAN STOVE I COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF NEWHJERSEY.

Application filed November 24, 1913.

To-all 'to/10m t may lconcern 1 Be 1t known. that l, EDWARD BOEKENKAMP,

' a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new. and useful Improvements in Means for Raising and Lowering Combustion-Tubes, of which the following is a specification, reference being had therein to the accompanying drawing.

'My invention relates to improvements in means for raising and lowering combustion tubes.

vThe object of my invention is to provide means whereby the combustion tubes may be readilyraised and supported away from the wick trough so that the burner can be readily lighted the burner has been lighted. The structure also provides means whereby the combustion tubes may be supported above and away from the wick, so that'the oil by capillary attraction will not work its way up on the combustion tubes when the' stove is not in operation- In stoves of: this character it has been found that when the 'combustion tubes are left in a downward position, resting in a wick trough, the oilby capillary attraction creeps up on the combustion tubes and causes the stove to smoke when it is first started.

Anotherobject of myv invention iis to provide .a simple, cheap and effective means whereby the combustion tubes can be raised on a burner in which a wick stop is used and having certain details of structure and combination of parts, hereinafter more'fully set forth.

Referring now to the drawings: Figure 1 is a vertical sectional view of a burner showing my improved combustion tube raising device full line in operative position, and also is arranged inthe usual showing them in dotted lines 1n a raised position. Fig. A2 is a detached perspective view of the raising lever, showing the same extending through the slot in the guide plate andshowing the combustion tube supporting member removed.

'Referring now to the drawings, 1 represents the ordinary wick burner having at its upper end the usual trough 2, in which manner the wick 3; raised 'and lowered by the said wick being but preferably that any i desired means,

shown in dotted lines Fig. 1. ri`he upper end oi the inner wick tube has a diaphragm i extending across the central opening therein and provided witha downwardly turned outer edge which is secured to the wick tube by means of solder, as .clearly shown in Fig. l of the drawings. This diaphragm 4 is provided with an -upwardly extending portion 5 screw-threaded as indicated at 6. This central upwardly extending portion 5 of the diaphragm is provided with a central opening- 7l therethrough, the Jurpose of which will be hereinafter more ilully described.

Resting upon the flange 8, ofthe central portion 5 which is formed by the reduced screw-threaded portion 6, is a wick stop 9. This wick stop, as shown, is of a diskshaped form having perforations. therein and having at its outer edge a downwardly vand outwardly extending portion 10. The

does not in any way aii'ect the operation of the stop.

Screwed upon the reduced threaded portion 6 of the central portion 5 is a nut 1 which is adapted to screw down upon the wick stop 9 and clamp the saine tightly upon the ledge8 carried by the central portion 5. By this structure it will be seen that the wick stop is removable.

The combustion tubes are of the type wellknown having the perforated outer'wall 13, and inner Wall 14 surrounded by a removable chimney 15, supported by the ring 17 carried by the lower end of the outer perforated tube 13. i This specific structure of combustion tube and chimney and means for supporting it is described in an application filed OctoberQ/th 1913, Serial No. 797,580.

having its upper end reduced and through the said slot is an outwardly turned end 22 of the rod 23. The outer end of the #outwardly turned portion 22 of the rod on 'the outside of the plate 19 is provided with a -knob for grasping and operating said rod. This rod is provided with a crank-shaped portion 24, belew the plate 25, carried by the lower end of the burner 1, and through which the-rod 23 passes. rThe rod from this 4crank portion 24 extends upwardly through the burner and through the opening 7 in the central portion 5, carried by the perfo- *i rated plate 4. This rod, as shown in Fig'l of the drawing, extends a considerable disthe vfertical tance above the threaded portion 6 of thel enlarged portion 5. The upper end of the rod is reduced, as indicated at 26 and adapted to fit in a socket 27 carried by the plate 28. This plate 28, as shown,v is provided with openings for the purpose-of lightening the device and also to allow a free passage of ',air up through thel combustion tubes` This plate 28 rests against the lowenface of the transverse perforated plate 18 carried by .the interior of the combustion tube and the through a central opening' socket 27 extends therein.l

"'When the outwardly turned portion -22- of rodv23 is in the lower end -of the obl-ique,y slot 20, the-combustion tubes 13 and 14 rest' within the yflanges on each side of the wick. When it "is desired to raise the wick, all that is necessary to do is to move the outwardlyl turned portion 22 Aor" the rod 23 to the right, which will-cause it to travel upwardly on the' inclined lower face of the slot and at the same time rotate the rod 23. This causes the rod to travel upwardly and the plate 18 of the combustion tube resting upon the plate 28 will cause the combustion tube to be raised from the anges. The ortion 22 of 'the rod'23 is moved to theright until it reaches the straight horizontal portion 21,l whereit will remain with the combustion tubes fraised from the flanges so that the burner can be readily lighted. When it is desired to lower the combustion tube, the portion 22 'fthe rod 23 is moved to the left, which causes the rod 23 to rotate andat the same time to travel downwardly to bring the combustion tubes within the flanges, as clearlyr shown yin Fig. 1 of the drawings.

The central upwardly extending portion 5 carried by the diaphragm,- as heretofore ydesc'ribed,.is provided with anopening 7 through which the rod 23'passes. This elongated portion 5 serves as a4 guide for the rod 23 to prevent any twisting, yet allows of the free movement of the rod therethrough.

Having thus described my invention,what I claim and desire to secure by Letters Patent is: y

1. .The combination with a burner having combustion tubes, of a wick stop, a diaphragm spanning the space within the inner wick tube adjacent the upper end and adapted to support the wick stop, a rod extending upwardly through the burner and through the diaphragm and adapted to sup ort the combustion tubes and means carried) by the lower end of the rod for raising and lowering the saine, whereby the combustion tubes are raised and lowered from or to the burner.

2. The combination with a burner having -fombustion tubes, of a wick stop, a plate means carried by the upper end of the rod for supporting the combustion tubes, and

` means operating with the lower end of the rod for raising and lowering the same. i 3. vThe combination with a burner having combustion tubes, of a wick stop, a. 'plate spanning the space Within the inner wick tube adjacent its upper end and rigidly supported thereby, said plate 'having an upwardlyex-tending sleeve at the center thereof and adapted to support' the wick stop, a rod extendiugupwardly through the burner and through the said sleeve, a plate carried by the upper end of the rod and supporting the combustion tubes, and means operating with the lower end of the rod for raisingv and lowering the same, whereby the combustion tubes are raised and lowered on the burner.

4. The combination with a burner having combustionivtubes, of a wick stop, a plate rigidly secured to the inner wicktube adjacent its upper end, a sleeve carried by the said plate and having a screw threaded upper end upon whichis adapted to be secured the wick stop, a nut on said screwthreaded portion and a rod extending| upwardly throughthe burner and through the sleeve and adapted to raise and lower the combustion tubes, substantially as shown and described.
