MEANS FOR RAISING- COMBUSTION-TUBES 0N BLUE-FLAME WICK-STOVES.

Lloseta.

To all whom t may concern Be it known that I, HENRY RUPPEL, a citizen of the United States, residing 1' at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful linprovements in` Means for Raising Combustion-Tubes on Blue-Flaine il/l/'ick-Stoves, of which the followinglis a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in means for raising combustion tubes on bluellame wick-stoves, and pertains more particularly to that character of stove used in my copending application Serial No. 731,901, filed November 16th 1912.

rlhe object of my invention is to provide means whereby the combustion tubes maybe raised and supported away from the wick trough so that the oil by capillary attraction will not work 4its way up on the combustion tube when the stove is not in operation. lt has been found that in stoves of this character, wherethe combustion tubes are left in a lowered position and resting in the wick-trough, the oil by capillary attraction creeps upwardly on the combustion tube. rlhis causes the stove to smoke when first started and it is the main object of my invention to avoid this.

A still further object of my invention is to provide a simple, cheap and effective means that can be readily attached to the ordinary combustion tubes, whereby the combustion tubes may be readily raised and supported above the wick-trough.

In the accompanying drawings-Figure 1 is a side elevation of an improved burner showing the combustion tube applied thereto and partly broken away. Fig. 2 is a vertical sectional view showing the combustion tubes in their lowered position. Fig. 3 is a vertical sectional view similar to Fig. 2, showing the combustion tubes in their raised position. Fig. 4 is a perspective view of the wick-trough and perforated coinbustion tube in their separated position, showing the means whereby the combustion tube is raised and held away from the wicktrough. y

Referring now to the drawings, 1` represents an outer wick-tube; 2 the inner'wick tube and 3 the wick therebetween. Any suitable form of wick-raising device may be used and, therefore, I have not shown this.

Specification of Letters Patent.

Application filed August 27, 1913.

serial No. 786,942.

The upper end of the outer wick-tube 1, has an outwardly extending annular flange 4, and the upper end of the inner wick-tube 2, is provided with an inwardly extending flange 5,- which, together with the flange Ll, forms the wick-trough proper.

Extending across the central space within the flange 5 of the wick-trough is a perforated diaphragm 6, having at its outer end an L-shaped flange 7 which extends downwardly into the flange 5 and lits against the inner wall of said flange. The outer edge of the l.-shaped flange 7, is provided with a plurality of upwardly extending l.- shaped prongs 8. The outwardly extending ends 9 of these prongs 8, extend in the path of travel of the wick 3, as shown in Figs. 2 and 3, and this serves to limit the upward movement of the wick.

As shown, the diaphragm 6 is preferably movable and the moving means consists of a central rod 10 having yits upper end screwthreaded at 11. The screw threads of the rod 10 mesh with internal threads on the central portion 12, which is suitably attached to the center of the diaphragm. The said central portion 12 of the diaphragm is provided with radially extending arms 13, which have their outer ends turned downwardly at 14C, and engaging the outer edge of the diaphragm. This construction serves to strengthen the diaphragm and lirmly hold its outer edge in shape and in proper position in relation to the flange 5 of the wick-trough and also to prevent the diaphragm from being warped or deflected out of shape by the heat of the flame. The said radially extending arms at a point inside of their outer ends are provided with a circular ring 15, the said arms 13 having the portions 13 extending beyond the ring, the purpose of which l will now proceed to describe.

The combustion tube 16 consists of an outer solid casing 17 and of two inner concentric perforated tubes 18 and 19, spaced apart and also spaced from the outer solid casing 17. The inner perforated tube 18, adjacent its lower end is provided with a plate 20, rigidly secured to the wall thereof and having a cent-ral opening 21 therein, which is the usual construction of a combustion tube. Secured to the lower face of the plate 2O is a ring 22, which extends downwardly in a vertical position. This ring is preferably provided with any number of ears 23 which extend upwardly through openings in the plate 20and are turned overV edges 26, terminating in. upwardly extendy ing edges 27. The downwardly extending portions 25 at the ends of thel edges 27 are provided with downwardly extending ears orlugs 28, which form stops to engage the outer faces of the extensions 13 of the radially extending arms 18 to limit the movement of the combustion tube.

As shown inligs. 1 and 2, thering 22 rests. upon the radially extending arms 13, and'when in said position the lower ends of theperforatedtubes 18 `and. 19 are also resting' upon the bottom of the wick trough.

`When it is desired to raise the combustion tubes, it is only necessary to rotate the same by the handle 2 9, which causes the downwardly inclined edges 26 toride upwardly over the radially extending arms 13, until the lower edges thereof: have been reached, when the arms drop into the upwardly inclined portions 27, and the lugs 28 prevent further rotation of the combustion tube.

This operation as clearlyillustratedin Fig.V

3 of the drawings, raises the two perforated combustion tubes 18 and 19 out ofthe wick trough and so exposes the wick that it can be readily lighted, or after. the stove has been extinguished, raises the perforated combustion tubes out ofthe wick trough. and

prevents oil by capillary attraction from creeping up on the combustionV tube.

Attention is particularly directed to the fact that the ends 9 of the prongs 8 are pointed or reduced. `This reducing of the ends 9 is found to be of substantial imporn tance in a device of this character in order to prevent any substantial interruption in the continuity of the annular flame, and to facilitate the travel of the flame around the wick when it is lighted at one point which is the usual way of lighting these burners. By having the point 9 reduced substantially ashere shown, the Aouter edge of the top of the wick is substantially uninterrupted so far as lthe travel of the flame is concerned there-around when itis lighted at one point, the substantially uninterrupted outer edge of the wick forming what might be termed a flame communication for the spaces of the burner. trough.

wick between the said prongs. By forming the prongs as here shown there are provided substantial horizontal surfaces at their inner ends `to act as wick 'stops while their outer ends as stated, leave the outer edge vof the top ofthe wick substantiallyA uninterrupted f so far as the travel of the flame there-around when lighted is concerned, and the reduced iportion is also found to be of importance in maintaining a continuity of the flame around the top of the wick which is essential in the typebof wick burners here shown (those having thel perforated` combustion sections) in4 order to maintain an even flame at the top of theperforated combustion section. s

Noclaim is made herein broadly to the wick-stop because the 'generic invention 'of ythewick-stop here disclosed is made the subject matter of my Lao-pending application Serial No., 731,90 l
