' Be it known that I, CHARLESSH. STENBERG, a citizen of the United States, anda' resident of Radcliffe, in the county of Hardin and State of Iowa, have invented a certain new and useful Oil-Feed for Wickless Gil-Burners, of which the following is a specification.

The object of my invention is to provide a reliable oil feed for a wickless oil burner of simple, durable, and inexpensive construction.

More particularly it is my object to provide such an oil feed having a wick-Siphon to carry the oil from the oil reservoir and drop it into the feed pipe.

Another Objectis to regulate the carrying capacity of the wick-siphon automatically so as to produce a flame suitable to maintain a lcertain `predetermined temperature sur-- rounding the burner under varying atmospheric temperature.

With these and other objects in view, my invention consists in the construction, arrangement anci-combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:` v

is mounted a funnel shaped casting 2, having an arm 2a. Mounted on the arm 2a is a receptacle 3 having two compartments 3a The compartment 3a communicates with the compartment' 8b near the bottom to allow oil to lflow from the compartment 3h. into compartment 3a. Mounted on compartment 3b is an inverted jug 3c which is provided with 'a cork 3e mounted on a bail dwhich extends up over the jugm The bail 3d fits into a forked support 3t which is 4secured to the receptacle 3. The receptacle 3 with the jug 3c constitutes the oil reservoir. With the jug vin place as shown in Fig. 2 the oil is maintained in the compartments 3b and 3a on a level with the opening in the neck 'of jug. When it is desired to replenish inverted and replaced in the rece tacle 3.-

When the jug is in place the bailBd 1s shoved down which draws the cork from the neck of the jug and allows free flow of oil. The

iow of oil is regulated by the well known principle of atmospheric pressure to maintain the oil level as described above.

-A wick I is mounted in a'tube 5 and extends up from the bottom of the compartment 3a ofthe oil reservoir and over said compartment wall and down into the funnel 2 for a pur lose described hereinafter. rlhewick is pre erably made up into 2 or more narrow wicks, each wick held in separate compartments 5", clearly` shown in Figs. 4f, 5 and 6. The tubeconsists of two main parts 5 and 5a. The wicks are placed in the art 5 and the cover `5a is slipped over from t e top. A removable bail 6 is pro, vided to suspend the tube from the automatic regulator lever or any other suitable the tube, in that end which extends down into the oil reservoir is preferably successively shorter and is closed and perforated at,5c and 5". 'See Figs. 6, 7 and A small extension, of that section of the I These features are explained hereinafter.

To the end Off the horizontal SeCtOn f ber of lever 8 by means of a link 10.

the feed pipe burner which absorbs i which tube 5 .iiow of oil lit carries as a lconstant flow ieaiev 1 is connected a burner by means of threads A. A bracket 17 supports the feed pipe at this end. An asbestos ring T is set in a channel in the base of the the oil and serves as a means of ignition when the oil is fed `into said channell by means of the feed pipe 1 `which communicates,l with said channel by vmeans of the hole' 1S.

The chimney V having an inner tube U sits loosely on said burner. The inner tube provided with a cap A bracket 11 is secured to the horizontal section of the feed pipe 1. A thermostat 12 and a pivoted lever 13 which engages with the thermostat at its free end is mounted on the bracket 11."

On theupper end of casting 7 is pivotally mounted a lever 8 having a'horizontal and a vertical member. 0n the free end of the horizontal member of lever 8 is hung the by means of the bail 6. At a point between the base and upper 'end of the casting 7 is pivotally mounted a lever 9. The upper end of lever 9 is pivotally connected to the free end of the vertical mme he lever 9 is adjustably connected to the upperend of lever 13 by means of a rod 14 having a threaded ,member 15 on which is fitted a threaded bur 16.

Having described the mechanical construction of the diiferent parts, I will now explain how the different parts function individually and in combination.

Presuming that the oil reservoir hasa full supply of oil and that all parts are in place as shown in 1. The wick-Siphon opposite endr of the has a greater carrying capacity the lower constant level in 8a where the receiving end of the wick-A siphon is submerged .in the oil. It is a well known fact that a wick is not nearlyY so subject to Vclogging or variations in the valve commonly maintaining a minute and of oil for a heater of this kind.. It may be said in this connection that the burner, the thermostat with the actuating connections and the jug with its attachments are of ordinary construction, hence I deem it unnecessary to give minute used for such Q explanation oftheir functions.

If it`should be desired to reduce theilame the wick-Siphon is raised slightlyy which reduces the flow of oil, as a result of thewell known principle of a ,caution against the burner where it is Ithat the wicks can always Siphon whose capacity is in proportion to the length of the discharge end extending below the level of the furnace of the liquid. VAs an additional means lof controlling the flow of oil by raising and lowering the wick-Siphon I divide the wick into 2 or more parts and make the different parts of different lengths so that when the wick-Siphon is raised to a certain height one of the shortest parts will become free from contact with the oil and thus reduce the flow of oil. As the wick- Siphon is withdrawn farther each successive part will be withdrawn from the oil and lessen the flow of oil. And vice versa. when an increase of the flame is wanted. As a precaution against extinguishing the flame when the automatic regulator is used to regulate the flame I provide an extension which will extend down into the oil when all other parts are withdrawn and maintain a minute flow of oil. As still another additional means of controlling the flow of oil by raising an lowering the w-ickesiphon YI taper the discharge end. The flow 0f oil is greater when the whole width 0f the wick is extending below the oil pered end'extends below. As a further preextinguishing the flame when the automatic regulator is used I 'extend one of the wick parts with a tapered end down so that it willA extend below the oil level when the actuating lever 0f the automatic regulator yon which the wicksiphon is suspended reaches the extreme height of movement.

It can be seen that theJ wick-Siphon will maintain any jdesired quantity constantly without any perceptible varia- It can also be seen that the thermostatic level than when only the taflow of oil regulator will control the position of the Y wick-Siphon so as to maintain any desired temperature surrounding the burner..

To place the wicks in the tube the cover 5a is slipped off upward and a suitable wick is placed ineach compartment. I have provided a closed end for each compartment so be placed in accurate position.- The closed ends are perforated at 5 toadmit the oil tothe wicks. TheY tube is also perforated on the sides near the end 5d to admit oil to the wick.

lSome changes may be made in the construction and arrangement of the parts of my device without departing from the essential features and purposes thereof, and it ismy intention to cover by my claims any modified forms of structure or'use of mechanical equivalents, which may be reason# ably included within their scope.
