Other objects and advantages will appear from the following description taken in connection with the accompanying drawings, wherein: Figure 1 is a top plan view of the oil container vention shown in Figures 1 to 6, reference'char of a lantern, surrounding casing, font and one 40 form of my improved burner, all in assembled relation; J Figure 2 is a side View of the structure shown in Figure 1 with the oil receptacle and casing shown partly in section and partly broken away; ?gure 3 is an enlarged sectional view of the burner shown in Figure 1, the vsection being take along the line 3—3 of Figure 4; Figure 4 is a central longitudinal sectional View taken on the line 4—4 of Figure 3 with the wick tube shown partly in elevation; Figure 5 is a transverse section of the burner taken on the line 5—5 of Figure 4; Figure 6 is a perspective view partly broken 55 away of the two parts of the burner, spaced from 25 , acter 20 represents an outer annular casing of 35 a lantern base into which the oil receptacle 2! rests. The casing 20 has air openings 20’ as is usual in this'type of base. The receptacle 2| is provided with a font cap 22 which has the wick tube 2-3 surmounted by the burner 24. It will be 40 understood that the outer structure of the Iantern may be any of a number of types or the burn er 24 may be applied to a lamp, cigarette light er or other lighting or igniting device and when used as a lantern the top dome may be any of 45 a number of types. Mounted at the ‘top of the wick tube 23 is a pan 25 which as shown in Figures 3 and 6 has a central opening 26 through which the upper end of the wick projects and the pan extends some 50 distance laterally and longitudinally from the wick. The dimensions of Figures 1 to 6 as well as the other ?gures of the drawings are in correct pro portion to those of actual structures employed 5:; 2 10 15 20 25 135 2,138,128 by me. In one type of burner which I have found 9 inclusive, the skirt 4!! is supported at its corners quite satisfactory, the pan is 3% of an inch high. on rods 4| extending upwardly from the font, this skirt being located some distance above the top Secured to the upper edge of the pan and ex of the pan 25. The space between the top of the tending outwardly and downwardly are two ?ar ing plates or sheets 21 which form air directing pan and the skirt 40 is closed at the ends by surfaces leading to the top of the pan and secured channel shaped plates 42 which extend a short to the top of two end plates 28 is a skirt 29 formed distance along the sides of the pan leaving be of side and end plates which as will be seen in » tween them spaces 43 for the supply of air to the Figure 4 is spaced vertically above the skirt 29. ?ame. Thus it will be seen that at each side of the pan there will be two currents of air supplied While the end plates 28 may be permanently at to the ?ame, one below the skirt and one above tached to the top of the pan, in the form of in vention I have shown, they are formed with inset the skirt; whereas at the ends of the ?ame, and portions 30 which ?t into the ends of the pan and also for a distance along the side, the air'will be provide a support for the skirt. The skirt as } supplied only from above .the skirt. In the form of invention shown in Figures 10 will be seen is formed of four curved plates and by reference to Figure 5 it will be seen that the to 13, I provide a box-like structure 50 having side plates of the skirt and the side plates 21 sides 5! and ends 52 which are provided with form a passage between them for supplying air downwardly extending portions 53 for supporting to the ?ame, this passage curving convexly toward the structure from the font. The skirt 54 as will the ?ame and being of decreasing area in cross be seen from Figure 12 is supported at some dis section as the ?ame is approached. Furthermore, tance above the pan 25 while the body portion of it will be noted that the curvature of the plates the structure 50 extends below the pan on the and the passage between them increases as the sides and ends and is spaced from the pan at the ?ame is approached. It will also be noticed that sides and in contact with the pan at the ends. the spaces at the ends of the pan are closed by This leaves an air conducting passage 56 at the side of the pan, there being, however, no com the plates 28, these plates extending a short dis tance along the side of the pan thus also closing munication at the ends of the pan. Plates 53 are cut away at 53’ to provide an additional space part of the space between the side plates. , for air to enter at the sides beneath the skirt. In operation, when the burner shown in Fig The form of invention shown in Figures 14 to ures 1 to 6 is lighted, the pan 25 quickly becomes 17 is the same as that shown in Figures 1 to 6 heated and ?lled with oil vapor, this vapor burn ing quietly with high luminosity. Air is fed to except that I have added two ?ame spreading the flame between the skirt 29 and the plates 21 plates 60 which are supported in any convenient and also above the skirt 29. I have indicated the manner as by posts 6| extending upwardly from direction of the currents as guided by the plates the corners of the skirt 29. The upper edge of or wall by solid arrows in Figures 4 and 5. Should each plate 60 has an upward curve as indicated the burner be subject to a violent draft, the air at 62, this edge lying in a vertical plane and as reaching the flame will take a course indicated will be seen from Figures 14 and 16 the plates 60 approximately by the dotted arrows. Eddies in extend longitudinally beyond the pan terminat the air will be created but the directions surfaces ing at approximately in line with the outer edge or guiding walls 21 and 29 are such that these of the skirt 29. The plates 60 ?are outwardly, eddies will fall outside the ?ame area and not there being a slight outward bulge in the plates extinguish the ?ame. Should the draft proceed as indicated at 63. With the plates 60 applied from the end of the pan as indicated by the ar v45 rows in Figure ll, the plates or barriers 28 will prevent the blowing out of the ?ame by a draft entering between the skirts; whereas the current of air over the end plate of the skirt will be direct ‘over the ?ame. By the form of the passage be tween the skirt and plates 21 the air passes up '50 ward at an accelerated speed and the form of the plates is such that the air passes smoothly along them without the creation of excessive eddies. To prevent the possibility of such eddies put 25 30 35 40 disclosed. The ba?le shown in Figures 18 and 19 may be obviously, if desired, applied to any of the forms 50 of burners disclosed as well as other burners now in use. tinguishment of the ?ame will be limited to that wardly and upwardly gradually curved passage part on one side of the ba?le and immediately meeting the base of the ?ame at an acute angle, a barrier to prevent ?ow of air to the base of said ?ame at each end, and means supplying air to the ends of said ?ame at a higher elevation, said latter means comprising guiding walls curving inwardly and upwardly and meeting the ?ame at an acute angle. 2. In a burner, a wick holder, a pan surround ing said wick holder, metal side sheets secured at their topv to the top of the pan and bent'con vex to the pan and of gradually increasing curva ture as the pan is approached and a skirt sup; ported above said pan, said skirt being formed of side and end sheets, said last mentioned side and end sheets being of substantially the form and curvature of said ?rst mentioned sheets. 3. The structure claimed in claim 2 wherein when the draft has ceased, the part of the ?ame which is still burning will relight the part that has been extinguished. This ba?le as clearly shown in these ?gures is a thin plate formed with sup porting legs 36 suitably secured to the top of the 65 pan 25 midway of the length thereof. A similar baffle can be supported from the skirt 29 of the form of invention shown in Figures 1 to 6. In the form of invention shown in Figures 18 and 19, a single skirt 3'! is employed which is secured at 70 its top to the top of the pan. In order to func tion satisfactorily, the lower edge of the ba?le 35 should be spaced from the bottom of the pan or the wick at about the distance shown in Figures l8 and [9, that is, less than 1% of an inch. In the form of invention shown in Figures 7 to 20 1 to 6. It will be understood that the plates 60 may be applied to any of the forms of burners baffle 35 shown in Figures 18 and 19 that the ex conditions, I ?nd that by the employment of the 15 the ?ame is considerably longer horizontally than that produced by the structure shown in Figures Having now described my invention, What I claim'and desire to secure by Letters Patent is: l. A burner having means for forming an elon gated ?ame, means for supplying air to the sides of said ?ame consisting of walls forming an in 55 ting the ?ame out, as may occur under extreme 10 60 65 70 75 3 2,138,128 there is provided additional side sheets located above and spaced from said skirt, said addi tional. sheets curving gradually inwardly and upwardly and bulging outward along their length. 4.
