12 Claims. This invention relates generally to. oil burning j stoves having burners of the wick type and refers more particularly toimproved means for igniting the wick.

Considerable dimculty and inconvenience have been encountered in the past in igniting the wick in an oil burner of the type commonly employed on stoves due to the fact that the combustion drum or chimney ordinarily renders thewick inaccessible. In the past it has been necessary to lift or tilt the drum or chimney in order to render.

the wick accessible for ignition and this is not only inconvenient but involves handling of the soiled drum which is'objectionable.

- It is, therefore, one of the principal objects I of this invention to overcome the above objecillustrating the lighting tip in operative relation Figure 1 is a semi-diagrammatic view, partly in section, illustrating my improved wick igniting means in association with'an oil burning unit;

Figure 2 is a fragmentary eIevational viewoi a part of the oil burning unit shown in Figure 1 and to the wick;

tions by providing means rendering it possible to ignite the wick of an oil burning unit without handling or otherwise disturbing the chimney or combustion drum.

Another object of this invention resides in the provision of a wick having a section movable relative to the remaining portions of the wick through the chimney or combustion drum to a position, substantially above the upper end of the latter where it may be conveniently ignited. After the movable section of the wick has been ignited, the latter is returned to its original position in operative relation to the wick and thereby serves to ignite the wick.

Still another object of the present invention resides in moving a section of the wick to its pro--' jected position where it may be conveniently ignited and returning the section of the wickto its original position with respect to the remainder of the wick for igniting the latter by remote control means locate'd for convenient manipulation by the operator.

Another feature of this invention consists in the provision of remote control means positioned for convenient manipulation by the operator at the front of the stove and operativelyconnected to the movable section of the wick bymeans of .a

Figure 3 is a sectional view takenrsubstantially on the plane indicated by the line 3--'3' of Figure' -1;

. Figure 4 is a plan view of a stove having a plurality'of oil burning units and illustrating the arrangement of the remote controls forthe igniter tips;

Figure 5 is a fragmentary sectional view illus-,

trating one manner of attaching the lighting tip to the actuating wire;

Figure 6 is an elevational view illustrating still another'means for attaching the lighting tip to the actuating wire.

Referring now to the drawings, it will be noted fuel reservoir l3 through the medium of a feed line in the iorm'of a conduit l4 having a valve l5 therein for controlling theflow of the'iuel iromthe reservoir l3 to the wick tube H. The valve is supported for convenient manipulation by the operator on the control panel It at the front side of the stove and the burner I0 is spring wire actuator possessing sufficient flexi' bility to permit bending the same within its elastic limits to various irregular shapes. 7

A further advantageous feature of this invention resides in the provision of a readily detachable connectionbetween the movable section of the wick and the spring wire actuator. As a result, the movable section f the 'wick may be readily replaced when desired without the necessity of replacing the entire wick. i

' A still further object of this invention'resides in the novel arrangement of the several remote control igniting means on a stove embodying a pluralitymf oil burning units. "This feature, as

well as the'foregoingobjects, willbe made more apparent asthe description proceeds, especially the accompanying drawings, wherein:

suitably secured to a part I! of the stove in rear of the control panel 15.

The oil burner I0 is further provided with a pair of inner and outer perforated tubes 18 and I9 supported in concentric relation on the upper ends of the inner and outer, flanges 20 and 2i respectively of the U-shaped wick tube. of these tubes are apertured to insure' supplying the volume of air to the space above the wick tube required .for eflicien't combustion and the outer perforated tube 19 is preferably surrounded by an air baiiie tube 22. The air baili'e tube .22

is suitably supported on the tube I 9 in concentric relation to the latter and provides an annular space around the tube {9 for the flow of air. In

accordance with conventional practice, a chimney or combustion drum 23 is supported with theside walls thereof poncentricwith the air baflie j draft of air in proximity to the wick which is' tube 22 and is constructed to facilitate the upnecessary in order to obtain eflicient combustion.

Wick type oil'bumer units of the general construction briefly described above have been used Bothextensively for a long period of time and although they operate satisfactorily for the purpose in tended, nevertheless, they present the problem of igniting the wick without the necessity of lifting or tilting the combustion drum and associated parts to render the upper end of the wick accessible. As pointed out above, the present invention contemplates a relatively simple and inexpensive attachment to the burner rendering it possible to conveniently ignite the wick without disturbing or handling the combustion drum or associated parts of the burner. In detail, attention is directed to Figure 2 of the drawings wherein it will be noted that a portion 24 of the wick i2 is moved from the remainder of the wick and thereof shown in Figure 1 where it is elevated a substantial distance above the top of the combustion drum so that it may be conveniently ignited. The lighting tip 24 is moved between the concenthe actuator is clamped in place by tightening the nut 31. If desired, a pair of washers may be positioned" on the shank of the stud at opposite sides of the flexible wire actuator to effect the clamping action. This arrangement provides a' relatively simple, inexpensive attachment which lends itself to rapid assembly and disassembly.

It may be pointed out at this time that the delivery end of the tube 3! or, in other words, the

end thereof adjacent the fighting tip 24 extends vertically and inasmuch as the length of spring wire is normally straight, it follows that the lighting tip is moved vertically or substantially trically arranged perforated tubes i8 and I9 by means of a spring wire actuator 25 having one end removably secured to the tip by either of the two methods shown in Figures 5 or 6. In Figure 5, the free end of the actuator is merely. formed to provide a loop 26 and the tip is secured to the loop by meansof a cotter pin type fastening element 2?. In Figure 6, the tip is riveted to a lug 28 having a threaded sleeve 29 engageable with a correspondingly threaded portion 30 on the free end of the flexible wire actuator. In either case, the tip is readily removable and can be replaced when desired.

The spring wire actuator extends downwardly through a suitable opening formed in the base of the wick tube opposite the tip 24 and is extended through a' casing in the form of a tube 3| having the upper end brazed or otherwise suitably secured to the wick tube. The casing 3| is bent to the shape required for convenient invertically regardless of the bends in the casing 3 i. It'may be pointed out at this time that the movement of the lighting tip 24 to its raised and lowermost positions is positively limited by means of a pair of stops 38 and 39 in the form of lugs welded or otherwise suitably secured to the rod 32 at points spaced from each other longitudinally thereof. The lug 39 is adapted to engage the inner side of the control panel 16 on the stove to limit the extent of upward movement of the lighting tip and the stop 38 is adapted to abut a part of the stove structure to limit the downward movement of the lighting tip.

When the several parts of the igniting attachment are in the dotted line positions thereof shown in Figure l, the lighting tip'24 assumes a position within the wick tube to form, in effect, a continuation of the wick. Assuming that the parts are in this latter position and that it is desired to ignite the burner, the operator merely exerts a pull on the rod 32 in an outward direction until the. stop '39 on the rod engages the inner side of the control panel 16. As the rod 32 is moved outwardly by the operator, the spring wire stallation in the stove and serves to guide the flexible wire actuator throughout its movement relative to the casing.

As shown-in Figure 1, the flexible wire actuator extends out of the free end of the casing 3| and is secured to a control rod 32 mounted for reciprocation on the stove. The control rod extends through a suitable opening formed in the control panel iii of the stove and is provided with a handle 33 readily accessible from a position at the front side of the stove to reciprocate the rod. It will also be observed from Figure 1 that the rod is provided with a downwardly extending return-bent portion 34 intermediatethe ends and the end of the return bend is fashioned to form a loop 35. The loop 35 is adapted to receive a stud 36 having a head engaging one side of the loop and having a threaded shank portion extending through the loop to the opposite side of the latter for receiving a clamping nut 31. Upon reference to Figure 3, it will be noted that the shank-is provided with an opening extending transversely therethrough and so located that it actuator 25 is advanced relative to the casing 36 from the dotted line position shown in Figure 1 to the full line position shown in the same figure. As a result, the lighting tip is elevated to a position substantially above the combustion drum 23 and may be conveniently ignited. After the lighting tip is ignited, the operator merely pushes the rod 32 inwardly until the stop 38 abuts the frame member 40. This inward movement of the rod returns the lighting tip to its original position in the wick tube and communicates the flame to the remainder of the wick.

The above construction not only affords a relatively simple, inexpensive and convenient arrangement for igniting the wick but, in addition, is of a nature to occupy the minimum space so that a number of units, may be installed in a stove without the necessity of increasing the size of the latter. In this connection, attention is directed to Figure 4 wherein it will be noted that two pairs of burners 42 and 43 are diagrammatically illustrated in the positions they normally assume in a stove. In the present instance, the rear pair of oil burning units are respectively equipped with igniting attachments 44 and 45 supported adjacent each other in the space providedbetween the burner -units of each pair. The

. ments 46 and 41' suitablysupported at opposite sides-of the stove. The particular construction of the igniting attachments shown in Figure 4 and the manner in which the latter are opera-, tively connected to their respective burners are the same as previously described in connection with Figure 1-. Accordingly, thecillustration in Figure 4 is .merely diagrammatic and is for the sole purpose of illustrating the convenient man aster ner in which the lighting attachments may be arranged on thestove. a
