MEANS FOR RAISING AND LOWERING COMBUSTION-TUBES.

Applcation'led February 5, 1915.

be readily raised and supported away from the wick tubes so that the burner can be readily lighted and can be readily lowered after the burner has been lighted. The structure is also such that the combustion ,tubes may be supported above and away from the wick within the wick tubes 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 in which wicks are used, it has been found that the oil by capillary attraction from the wick works its way up upon the combustion tubes when the said tubes are left in their lower position resting upon the This causes the stoveto smoke when the stove is first lighted caused by the burning off of the oil that has worked its way up upon the combustion tubes.

Another object of my invention is to provide a simple, cheap and effective means whereby the combustion tubes can be readily raised from the wick tubes and held in a raised position and having certain details of structure and operation hereinafter more lfully set forth.

Referring to the drawings, Figure 1 is a vertical sectional view of a burner showing the combustion tubes supported by thek wick tubes and showing my improved rais- Fig. 2 is an enlarged perspective view of the combustion tube raising means.

Referring now to the drawings, 1 represents an ordinary wick burner formed of the inner wick tube 2 and the outer wick tube 3 between which is arranged the wick 4, all of which are of the ordinary construction. The lupper ends of the inner and outer wick tubes are provided with shelves 5 and 5B 6 upon which are supported the perforated combustion tubes 7 and 8 forming the com Specification of Letters Patent.

bustion section. These tubes are connected together in the ordinary manner. The wick 4 is raised and lowered by any desired means, and I have not shown the same.

The shelf 5 is formed rintegral with the perforated diaphragm 9. This diaphragm is provided-with a central opening 10 hav-V ing secured therein an upwardly extending enlarged portion 11 provided with a central opening 12. The upper end of this enlarged portion 11 is slightly reduced and screw-threaded as indicated at 13. Resting'y upon the liange 14 of the enlarged portion 11 is a wick stop 15. This wick stop, as shown, is of a disk shape having perforations therein and held upon the portion 10 by means of the nut 16. The outer end ofr the wick stop is turned downwardly at 17 and rests upon the diaphragm 9. The eX- treme outer edge of the downwardly turned portion 17 of the wick stop is provided with upwardly extending portions 18 having laterally turned ends 19 which extend across the space above the inner wick tube 2 and the outer wick tube 3, and form stops for limiting the upward movement of the wick.

The inner wick tube 1, adjacent its lower end. is provided with a transverse bar 2O having a central openingvtherethrough and through which loosely passes the vertical movable rod 21. This rod 21 extends upwardly through the opening 12 in the enlarged portion 11 carried by the diaphragm 9 and rests within the socket 22 carried by the plate 23 secured within the inner combustion tube 7. This plate is provided with openings to allow of the passage of air through the combustiontube. By this arrangement, it will be seenk that when the ro'd 21 is moved upwardly, the combustion section is likewise moved upwardly and supported by the said rod. The lower `end of the rod isprovided with a` disk 24 rigidly secured thereto. c

Secured to the lower end of the wick- -the shaft 29 it will be seen that the vertically disposed rod 21 is raised and lowered, and whereby the combustion tubes are raised and lowered. The flattened portions 33 and 34 are so arranged in respect to the crank 30 that the crank is in a downward position when the flattened portion 33 is in engagement with the disk 24 carried by the rod 21, and the flattened portion 34 against the disk when the crank is in a raised position shown in dotted lines F ig. 1.

As shown the rod 21 is round and passes loosely through the bar or guideway 2O at the lower portion of the wick tube 1, and as shown passes loosely through the enlarged portion or connection 11, by reason of which the rod 21 and disk 24 rotate when the cam 32 is rotated in engagement with the disk 24, due to its eccentric relation to the axis of the rod'21 and disk 24. This prevents a sliding action between the cam 32 and disk 24 which would create considerable friction between the dry engaging surfaces of the two members and make the parts work hard. Due to the turning movement of the rod 21 and disk 24, the cam rolls on the' outer surface of the disk 24, thus avoiding this friction and making the parts work easily and without any appreciable wear. Also as shown the upper end of the rod 21 is round where it extends within the socket 22 to permit the rotation of the rod as before stated.

By the arrangement of the two flattened portions 33 and 34, it will be seen that the weight of the combustion tubes upon the rod 21 causes the disk 24 to at all times enthe member 32, and when the flattened portion 33 is in the position shown in F ig. 2 of the drawings, the combustion sections are lowered and the member 32 held in said position.

By operating the crank 30 to bring it in a vertical position, it will be seen that the rounded. or oval end of the member 32 engages-the disk 24 forcing the same up` weight of the combustion section does not have any tendency to operate or oscillate the member 32 and thus the combustion seotions are held by their own weight in a raised position.

Having thus fully described lmy invenrLetters Patent is 1. In a burner, the combination with a wick tube, a fuel supply pipe arranged below the center of the wick tube and a vertically movable combustion section, of a vertically movable rod supported within the wick tube, the upper end of the rod engaging the combustion section, a disk carried by the lower end of the rod, the lower end of the rod over the fuel supply pipe, and a rotatable cam engaging the disk at a point eccentric to the axis of the rod and disk and arranged at one side of the fuel supply pipe, the cam projecting upwardly at all times above the fuel supply pipe,`whereby the disk is kept out of engagement with the said pipe.

2. In a burner, the combination with a wick tube, a fuel supply pipe arranged be` .low the center of the wick tube and a verof the rod over the fuel supply pipe and aV rotatable cam engaging the disk at a point eccentric to the disk and at one side of the fuel supply pipe, the cam projecting upwardly at all times above the fuel supply pipe whereby the. disk is kept out of engagement with the said pipe, a crank shaft for rotating the said cam, a bracket carried by the wick tube.v the said crank shaft having bearings within the said bracket.

3. 1n a burner, the combination with a wick tube, a fuel supply pipe arranged below the center of the wick tube and a vertically movable combustion section, of a vertically movable rod supported within the wick tube, the upper end of the rod engaging the combustion section, a disk carried by the lower end of the rod, the lower end of the rod over the fuel supply pipe, a

bracket carried by the wick tube above the fuel supply pipe, a crank-shaft rotatably mounted within the said bracket, a cam on the inner end of the said shaft, the said cam engaging the disk carried by the vertically movable rod eccentric to the disk and at one side of the fuel supply pipe, the upper edge of the cam mounted above the fuel supply pipe due to the location of the bracket which supports it, whereby the disk will at all times be kept out of engagement with the said pipe.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
