` varon-BURNER.

Specification of Letters Patent. Patented luay 13, 1919.

Application filed August 31, 1917. Serial No. 189,157.

T 0 all whom t may Concern y Be it known that I. VILLIAM C. COLEMAN, a citizen of the United States, residing at lVichita. in the county of Sedgwick and State of Kansas. have invented certain new and useful Improven'lents in Vapor-Burners, of which the '.tollowingis a speciication.

The present invention relates to means for utilizing vaporized `hydrocarbon or other fuel for an illuminant, and particularly tok that type of lamp in which an incandescing mantle or similar material is utilized.

One of the primary objects of the present invention is to provide an exceedingly simple and thoroughly practicable structure of a novel character, in which the initial vaporizing action can be secured by the use of ordinary matches, thus doing away with the necessity of an alcohol torch or a means for holding a burning liquid fuel.

A further and important object vis tok provide a stl'ucture that is very simple in its character, and in which the standard is so constructed that it alsol performs the function of an air supply tube.

A A still further object is to provide a vaporizing tube of a type that is elementary in character and is so associated with the remaining elements that vit can be' easily removed for the purpose of cleaning, repair or replacement, and is so constructed that while compact and relatively short in so far as the distance lbetween its ends is concerned, is nevertheless so arranged that the vaporizing zone is at a relatively great distance from the discharge nozzle or end, thereby materially lessening the danger ofthe latter becoming stopped or choked by carbon.

YVhile the invention may be embodied in various forms, there is illustrated in the accompanying drawing, a lantern having the improvements, Figure 1 being a vertical sectional view through said lantern, and Fig.l 2 a detail front view showing the arrangement of the burners with respect to the air tube and vaporizer.

vFig. 3 is a detail view of one of the burner tubes. l

ySimilar reference numerals designate corresponding parts in all the figures of the drawings. I' i i l ln the embodiment disclosed, a suitable base in the form of a font 3 isemployed having a filling opening which is thelboreof a sleeve l fitted into the upper portion ofthe font at one side of its center, this bore being internally threaded t0 receive a detachable plug 5 having an upper outstanding flange G beneath which is placed a packing gasket 7. The plug 5 contains a passageway 8 therethrough, the lower end of which is enlarged to receive an upwardly closing check valve 9. The upper portion of this passageway is branched, as shown at 10, said branches opening into a bore 11. A second plug- 12 is threaded into the bore 11 and .is provided with a passageway 13 therethrough of less diameter than the portion 14: between the branches 10, said portion l-l thus constituting a closure for the inner end of the plug 13 when said plug is screwed down upon the same. The outer end of the bore 13 has a flared or tapered seat 15 designed to receive the correspondingly tapered end of an air pump delivery nozzle.

lVith this arrangement if it is desired to lill the font 3 the plug 5 is unscrewed from the sleeve 4, and fuel can thus be introduced through the bore of said sleeve. The plug is then replaced. To place the fuel under pressure the tapered delivery nozzle of the pump is simply pressed into the socket 15, the plug 12 having lirst been raised from the seat 1-1. Air can thus be pumped through the plug 12 and plug 5 into the font, and this air will be prohilbited from returning by the check valve 9. When sufficient air lhas been introduced, the plug 12-is screwed inwardly until its inner end is -seated 4upon the part 14, so that the a.' passageway is sealed. y Y

From the bottom of the font .3 a .centrally disposed vertical `conduit 16 extends upwardly, and has its upper end connected to the lower end of a nipple 17 that is threaded centrally into the top of the font, said nipple having a passageway 18-therethrough, which includes a transversely disposed valve seat 19. A needle valve 2O threaded into a transverse stern 21 projecting from one side of the g nipple 17, cooperates with the seat, and thus controls the passageway 18.' This controlling valve has an exposed operating handle 22.

`The upper end of the nipple 17 is externally threaded and has screwed thereupon a horizontally disposed offset coupling 23, into the offset end of which is threaded thelower end of a combined standard and air supply tube 24. The lower and upper portions of this tube are vertically disposed and are co-nnected by an intermediate curved offset 25,' the upper portion 26 constituting a part of a mixing chamber, which chamber includes a transversely disposed head 27 threaded upon the upper end of the tube and held against turning by a set screw 28. The portion 26 of the tube, it will be noted, is substantially in line with the nipple 17. l

Depending from the head 27 are one or more burners, the present embodiment showing two. These burners include tubes 29 threaded into the under side of the head 27 and having caps 30 threaded on ytheir lower ends, said caps clamping/suitable screens 31 at the lower ends of the tubes 29 and having external annular grooves 32 which constitute means whereby the mantles can be securely fastened in place. The burners, it will be noted, are disposed on opposite sidesof the tube and are slightly below the offset portion 25.

The upper end of the nipple 17 has. a socket that is internally threaded. In this socket is ldetachably fitted the lower end of a fuelI conducting` and vaporizing tube 33, said lower end being flanged as shown at 34, and being held in place by a plug 35 surrounding the tube and screwed into the socket. The upper end of the tube 33 detachably enters an opening 36 formed in the underside of the offset 25, said upper end being disposed axially of the portions 26 of the comloiiied'l standard and air tube 24, so as to deliver longitudinally upward into said tube. This upper end of the tube 33 has a discharge nozzle 37 containing aI minute deliveryorifice 3S. Between its ends the tube 33 is provided with a coil 39 which. in the present embodiment, is vertically disposed, extendsaway from the tube 24and lies in a plane between the burners 30 and the mantles suspendedfrom said burners, but being directly acent thereto. The lower end of the tu e 33 preferably contains a wick or fuel strainer and retarder 40. In this structure, thesize of the tube, the thickness of the walls and the character of the coil are such that it may be initially heated by ordinary matches. In the practical embodiment of the invention a tube formed of brass three-sixteenths of an inch in diameter with walls 24 B. & S. gage .020 of an inch thick,l

and a' coil one yand three-sixteenths inches,

voutside diameter, has proven entirely satisfactory for theA purpose.

The top of the font 3-is provided with an upstanding boss 41, and surrounding the same-and bearing upon said font is a collar 42 provided with perforations 43 and a slot 44. Through said slot the stem 21 andv c ontrolling valvevproject. Supported on this collar is the bottom plate 45 of a globe holder having a central depending boss 46 that fits within the collar. The plate 45 is ally mounted. These standards also engage and secure a top ring 51 having an upstanding flange 52. Resting on the bottom plate 45 between the standards 48 and within the flange 52 isa suitable globe 53.

Extendingbver the said globe is a hood or. ventilator comprising a perforated collar 54 having a flanged portion 55 at it-s lower end that rests upon the ring 51 outside the flange 52.v The upper end of this collar carries a ca 55 having a central opening 5G therethroug that receives a stem 57 carried by the mixing chamber head 27. 'A nut threaded upon the upper projecting end of the stem bears upon the cap 55 and serves to hold the ventilator in place while permitting of its ready removal.

It is believed that the operation of the device will be readily apparent. Assuming that there is fuel under pressure in the font. the same will flow upwardly through the nipple 17 and through thevaporizer tube 33 if the\`valve 20 is open. .If the burners are in operation the heat therefrom will vaporize the fuel as it passesinto the coil 39 and the vapor will be delivered through the nozzle 37 upwardly into the mixing chamber 26-27. This upward flow will cause the air to pass upwardly through the combined air tube and standard 24. the bottom plate 45 having an opening '59 directly below the tube 24 to permit the air to flow freely into said tube. The vapor and air will of course mix in the chamber 26 and 27 and be delivered downwardly to the burners. In starting the lamp, itis only necessary to hold one or two burning matches at the coil 39, whereupon said coil will be suiciently heated to vaporize the fuel admitted thereto until the burners beglin to operate. This, as will be obvious, it eliminates the necessity of an alcohol torch with the essential paraphernalia accompanying the same, and also the necessity of a cup or other fuel holder with means for supplying it withl the necessary fuel. The structure also is obviously simple, the tube 24 performing a plurality of functions. in that it constitutes ay supporting standard for the burner, an air conducting tube'and also a partv of the mixing chamber. The particular lform of construction of this tube also provides a compact structure in connection with the vaporizing tube. said tube being readily removable for the purposes of cleansas proven a very great advantage asv inca/.tee

ing, repair or renewal. Another decided ad-V j vantage in the structure is that by reason of l the coil 39 being disposed between the lowerV and the upper ends of said tube, the` vaporizing action, whichr really takes place `at the entrance of the coil',` places the vaporizmg nozzle when the path of the vapor is considered, for said vapor of course necessarlly has zle. Consequently the danger of carbon colf'` lecting at the nozzleand choking'the small 'i delivery oriiice 38 is materially reduced.-

rlhe structure, however, considering @its length over all, is really short, thus'siernurving the desired compactness. y y

From the foregoing, it is thought th'at the construction, operation and many advantages of theherein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size,"shape, proportion and minor details of construc' tion may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention;
