(7) Application filed August 3 To all vc1~om it may concern:

(8) Be it known that I, WILLIAM C. COLEMAN, a citizen of the ITnited States, residing at Wichita. in the county of Sedgwick and State of Kansas. have invented certain new and useful Irnprovenients in Vapor-Burners, of which the -following.is <a specification.

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

(10) 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.

(11) A furthier and important object is to pro- vidle a structure that is very simple in its character, and in which tihe standard is so constructed that it also performs the function of an air supply tube.

(12) 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 it 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 tile distance between 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 of the latter becoming stopped or choked by carbon.

(13) While 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. 2 a detail front view showing the arrangement of the burners with respect to the air tube and vaporizer.

(14) Fig. 3 is a detail view of one of the burner tubes.

(15) Similar reference numerals designate corresponding parts in all the figures of the drawings.

(16) In the embodiment disclosed, a suitable biase in the form of a font 3 is employed having a filling opening which is the bore of a sleeve 4 fitted into the upper portion of the 1, 1917. Serial No. 189,157.

(17) font at one side of its center, this bore being internally threaded to receive a detachable plug 5 hlavinlg an tipper outstanding flange 6 beneath which is placed a packing gasket 7. The plug 5 contains a passageway 8 therethrough, the lower end of wvhich 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 14 thus coni- stituting a closure for the inner end of the plug 13 when said plug is screwed clown 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. – W”ith this arrangement if it is desired to fill 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 pomp is simply pressed into the socket 15, the plug 12 having first -been raised from the seat 14. Air can thus be pumped through the plug 12 ‘and plug 5 into the font, and 85- this air will be prohibited from returning by the check valve 9. When sufficient air has been introduced, the plug 12 is screwed inwardly until its inner endl is seated upon the part 14, so that the air passageway is sealed.

(18) lFronm the bottom of the font .3 a centrally disposed vertical conduit 163 extends up- wardly, and has its upper end connected to the lower end of a nipple 17 that is threaded centrally into the top of tile font, said nipple having a passageway 18 therethrough, which includes a transversely disposed valve seat 19. A needle valve 20 threaded into a transverse stem 21 projecting from one side of the nipple 17′, cooperates with the seat, and thus controls the passageway 18. This controlling valve has an exposed operating handle 22.

(19) The uapper 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 the lower end of a combined standard and air supp~ly tube ’24. The lower and upper portions of this tube are vertically disposed and are connected by an intermediate curved offset 25,1 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.

(20) 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 thie head 27 and having caps 30 threaded on their 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 sides of the tube and are slightly below the offset portion 25.

(21) The upper end of the nipple 17 has a socket that is internally threaded. In this socket is detachably fitted the lower end of a fuel 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 under side of the offset 25, said uipper end being disposed axially of the portions 26 of the combined standlard and air tube 24, so as to deliver longitudinally upward into said tube.

(22) This upper end of the tube 33 has a discharge nozzle 37 containing a minute delivery “orifice 38. Between its ends the tube 33 4is provided with a coil 39 wh~ich, in the 40present embodiment, is vertically disposed, extends “away from the tube 24, and lies in a plane between the burners 30 and the mantles suspended from said burners, but being directly adjacent thereto. The lower end of the tube 33 preferably contains a wick or fuel strainer and retarder 40. In this struc- ture, the size 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;~ and a coil one and three sixteenths inches, outside diameter, has proven entirely satis- factorv for the_ purpose.

(23) The’ top of the. font 3 is provided with an upstanding boss 1, 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 and controlling valve project. 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 provided with a central opening through which the stem 17 projects, said opening being surrounded by a reinforcing flange 47 that is borne upon by the coupling 23. The plate, it will be noted, thus is securely 70 clamped between the collar 42 and coupling and serves to secure said collar in place.

(24) Secured to the margins of the bottom platse 45 are standards 48 having outstanding pintles 49 on which the handle bail 50 is pivotally 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 is a suitable globe 53.

(25) Extending’~over the said globe is a hood or ventilator comprising a perforated collar 54 having a flanged portion 55 at its lower end that rests upon the ring 51 outside the flange 52. The upper end of this collar carries a cap 55 having a central opening S6 therethrough that receives a stem 57 carriedl by the mixing chamber head 27. A not 58 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.

(26) It is believed that the operation of the device will be readily apparent. Assuming that there is fuel under pressure in the font.

(27) the same will flow upwardly through the nipple 17 and through the vaporizer tube. 33 if the valve 20 is open. If the burners are in operation the heat therefrom will vaporize the fuel as it passes into the coil 39 and the vapor will be delivered through the nozzle 37 upwardly into the mixing chamber 26=227. This upward flow will cause the air~ to pass upwardly through the combined air tube and standard 24. the bottom p~late 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, it is only necessary to hold one or two burning matchies at the (coil 39, whereupon said coil will be sufficiently heated to vapor.

(28) ize the fuel admitted thereto until the burners begin to operate. This, as w~ill be ob- vious, has proven a very great advantag’e as 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 with the necessary fuel. The structure also is obviously ‘simple, the tube 24 performing a plurality of functions, in that it constitutes a supporting standard for the burner, an air conducting tube and also a part of the mixing chamber. The p~articu- lar form 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 cleans- ing, repair or renewal. Another decided advantage in the structure is that by reason of the coil 39 being disposed between the lower and the upper ends of said tube, the vaporiz- iug action, which really takes place at the entrance of the coil, places the vaporizing zone at a relatively great distance from the nozzle when the path of the vapor is coinsid- ered, for said vapor of course necessarily has to traverse the coil before reaching the nozzle. Consequently the danger of carbon cob= lecting at the nozzle ‘and choking the small .

(29) delivery orifice 38 is materially reduced.

(30) The structure, however, considering ‘its length over all, is really short, thius’securing the desired compactness.

(31) From the foregoing, it is thought that the construction, operation and many advantages of the herein 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, p)roportion and minor details of construction may be resorted to without departing fromt the spirit or sacrificing any of the advantages of the invention.

(32) Having thus fully described my invention,
