T ZZ whom it "may concern:

Be it known that wie, JAM-ns H. GRADEN and ZACK E; Gir-Anniv, citizens of the United States, residing at Ellenwood, county .of Claytoin-and State of Georgia, have invented new and useful Improvements iny Oil Burners, of which the following is a 'specie l'ication. a

This invention is directed to improvements in oil burners and pa'rticularly-` to means for preheating the oil to facilitate the vaporization of the latter intoy gas, for heating' or cooking purpdses;

in important object of to provide a vapor-generating device embodying a four-way ci cuit disposed in the flame zone of the burner and .discharging into the fuel chamber, the oil; being supplied to the burner through the four-way circuit and thusl vapor-ized into' gas without smoke.y odor, or formation of carbon.

A further object of the invention is to provide vapor-generating` means of the above described character which-can loe-readily apl plied to the burner as an attachment thereto and as readily removed, when desired, for purposes of cleaning, repairs, or replacement.

With these and other objects in view,V

which will become apparent as the descrip; tion proceeds, the invention residesv in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of references indicate like parts throughout the several figures, of which:

Figure 1 is a top plan vview of an oil burner with the invention applied thereto;

Figure 2 is a view of the burnerin side elevation, with a portion broken away to disclose the fuel chamber and air inlet;

Figure 3 is a plan view of the invention as det-ached from the burner and including inlet and cleaning plugs and nozzle; and

Figure 4lis a view in detail of the needle valve assembly.

Figure 5 is a detail elevation of the needle valve.

As shown in the drawing the burner is of hollow form embodying a fuel chamber 11 into which air is admitted through the bottom opening 12, the fuel escaping from the back end of the chamber into the

distributing chambers

13 and 14 extending longitudinally of the burner on opposite the invention isv rectangular casing'` 17, tothe front side of which is connected a V-shaped vapor gener'-v at-ing tube 18, the

side members

19 and 20 of which penetrate the casing 1.7 at the places shown. At the back or. outer side',` the casing is provided with a screw-plug 21 hav-Y ing threaded engagement in a clean-out open-- ing 22 in linewith tube 19, and anVV inlet kplug. 23 registeringwth the inner' end of tube 2O.` A second clean-out opening andv plug` may alsobe arranged in one end of the casing as shown at 24,' thus enabling the parts to be very` easily cleaned.` Extending from the front. of casing 1=7 and centered with. resgectA toA the tubes 19 and 2O of the V-shaped member, is a straight tube 25 which constitutes the outlet of casing 17. This outlet tube 25 penetrates the front end of fuel chamber 11 and is provided, at its penetrating end with a nozzle 26 which is detachable, the same having threaded engagement with the end of the tube as illustrated. Then kerosene or other oil is supplied to the burner by way of inlet plug 23, it passes through the four-way circuit provided by

tubes

19 and 20, casing 17 and outlet 25, and since these tubes overlie the fiame orifices of the burner, being thus well within the flame zone of the latter, it will be seen that the oil will'be tl'ioroughly preheated and, hence, supplied to the fuel chamber in such a state as to readily vaporize. The diverting of the oil through a four-way circuit within the flame zone of the burner, subjects the oil to the heat vof the burner in a safe and efficient Vmanner and insures its initial preheating prior to its passage to the fuel chamber.

The fuel supply to the chamber 11 is controlled by a long needle valve 27 which eX-.

tends through avalve guide at the back of casing 17 and through the vapor-generating tube 25, terminating in a tapered point 28 which engages the valve seat 29 in the nozzle 26. The needle valve has an operating handle 30 at its outer end and is threaded inwardly of the handle, as at 31, for engagement with the threads 32 of the packing nut 33 el' the valve guide. Nut 33 is threadedly engaged with oneV end ofYV the guide tube 3ft which has its other end screwed into the back ot' casing 17. Tube 34 engages in a bracket 35 at the front end of the burner and supports the iouravay circuit member in position, being itselr" held in place by a set screw 36.

By loosening the set screw and unscrewing` tube Sil from the casing 17, the four-way member may be readily removed from the burner, and by further separating the parts as shown in Figures and il, they may be easily cleaned. The device is likewise adapted to be readily and conveniently replaced, when desired, and in the practical application of the invention may be installed as a built-in or permanent part or' the burner or as an attachment to be applied thereto as above described.

In practice, we have found that the form et our invention illust 'ated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most eliicient and practical; yet realizing the conditions concurrent with the adoption ot our device will necessarily vary, we desire to emphasize that various minor changes in details of construction, prop-on tion and arrangement of parts, may be resorted to within the scope of the appended claims without departing from or sacrilicing any of the principles of this invention.

Having thus described our invention, and without enumerating variations and equivalents, what ave desire protected by Letters Patent is as set Yforth in the following claims: i

l. An oil burner having a uel chamber and means for supplying fuel to the said chamber, said means comprising a hollow casing, a V-shaped tube having` its ends in communication with the casing, fuel inlet means at one end of the V-shaped tube, an outlet tube extending from the casing and having its outer end penetrating the said fuel chamber, and valve means associated with the said casing and the said outlet tube thereof.

2. An attachment of the character specilied comprising a four-Way circuit member embodying` a V-shaped unit presenting inlet and outlet tubes, a vapor generating tube having a nozzle at its outer end, a connecting casing between the inner end of the vapor generating tube and the outlet tube of the V-shaped unit, a tubular valve guide connected withthe said casing in line with the said vapor-generating tube, and a needle valve extending longitudinally of the said guide and generating tube and engaging a valve seat in the nozzle of the latter.
