J ., assignor to Lovell Dressel Company, Inc., Arlington, N. J ., a cor poration of Maine Application March 24, 1936, Serial No. 70,583 ' 3 Claims. (01. 67-53) My invention relates to improvements in lamp burners of the type adapted for use in hand lan terns, and other lamps, and the same has for its object to provide a simple, efficient and re 0 liable burners capable of producing a large bright ?ame which will burn without smoking or ?ick erlng. » Further, said invention has for its object to provide a burner in which the ?ame spreader 10 is capable of producing a larger ?ame of greater lighting power or luminosity for a given size of wick than would be possible‘ to obtain in the absence of such ?ame spreader. Further, said invention has for its object to “ provide a device of the character speci?ed in which the ?ame spreader is constructed to main tain a predetermined height of the ?ame and to minimize the tendency of the ?ame to be drawn upwardly or “creep” as the lamp heats up, and which will permit of the lantern being used for heavy signaling without causing ?ickering or extinguishing. Further, said invention has for its object to provide a device of the character speci?ed in which the ?ame spreader is constructed to cause the air for supporting combustion to be directed towards the ?ame in directions extending more or less transversely thereof and to minimize the force and effects of ascending air currents upon the ?ame. Further, said invention has for its object to provide a device of the character speci?ed in which the primary air introduced for supporting combustion is combined with a series of jets of C: 91 supplementary air directed inwardly and down wardly into the ?ame. _ Further, said invention has for its object to provide a device of the character speci?ed in which a combined ?ame spreader and baffle serve to reinforce each other to form a strong, rigid structure. Other objects will in part be obvious and in part be pointed out hereinafter. To the attainment of the aforesaid objects 45 and ends my invention consists in the novel fea tures of construction, and in the combination, connection, and arrangement of parts herein after more fully described and. then pointed out in the claims. 50 In the accompanying drawing: Figure 1 is a side view of one form of burner constructed according to and embodying my said invention; Fig. 2 is an end view thereof; 55 Fig. 3 is a plan thereof; Fig. 4 is a vertical section taken on the line 4—4 of Fig. 1; Fig. 5 is a horizontal section on the line 5-5 of Fig. 2; Fig. 6 is a detail perspective view of the ba?ie member detached from the burner, and Fig. 7 is a face view of the blank from which the ba?le member shown at Fig. 6 is formed. In said drawing, the base portion In of the burner is provided with a lower reduced part II 10 having vertically and circumferentially extend ing grooves I2 and 13 therein serving as means for locking the device into the oil font of the lamp. The base portion 10 at its upper end, has a horizontal ?ange l4 and a central dome 15 shaped portion iii. A flat wick tube I6 is dis posed centrally within the base portion lll and dome-portion l5, and has its lower end project ing slightly below the bottom of said base por tion. The upper end of the tube 16 projects above the dome portion i5. The tube i6 is pref erably constructed from a piece of sheet metal having the vertical edges thereof interlocked as shown at IT. _ The base portion In below. the ?ange I4 is provided with aligned holes l8 serving as bear ings for the wick raising shaft 19 having star wheels 20 extending into the Wick tube IS‘. The ?ame spreader 2! is preferably formed from a piece of sheet metal and includes the . standards 22 for supporting the spreader 2! upon the ?ange M. The lower ends of the standards are provided with prongs 23 extending through slots 24 in the ?ange l4 and bent over whereby the ?ame spreader 2| is secured in place upon K. the ?ange. The upper part of the ?ame spread er 2i comprises the ?at side portions 25 and 26 formed integrally with the upper ends of the standards 22; the side portion 25 being integrally connected at both ends with the standards 22, and the portion 26 being integrally connected to one standard at one end and having a free end portion 21 directed inwardly and overlapping ‘the other standard at the inner side thereof. The side portions 25 and 26 are formed to‘ extend upwardly and inwardly at opposite sides of the broad sides of the tube It and are perforated as shown at 28, to provide upon each portion 25 and 26 a multiplicity of jet openings through which air passes to be discharged in relatively 50 small jets directed inwardly and downwardly to wards the upper end 29 of the wick tube IS. The upper portions 30 of the standards 22 provide imperforate vertical end walls disposed trans versely of the portions 25 and 26 at the ends 55 2 2,132,119 thereof and forming therewith an enclosure 3| which is of progressively increasing rectangular cross-sectional area towards the base thereof. The upper edges 32 of the portions 25 and 26 are convex with the result that the mouth 33 of the enclosure 3| is of progressively increasing width from the center to the ends thereof. The mouth 33 is relatively enlarged in area compared to the area of the mouth 29 of the wick tube1|6 and is disposed symmetrically with reference to and in elevated relation to said mouth 29. _ The enclosure 3| is reinforced by a baffle mem ber 34 formed from a piece of sheet metal stamped out and bent to provide a horizontal or trans verse imperforate partition or baille plate 35 sur rounding the wick tube |6 at points slightly below the mouth thereof, a suitable opening 36 being provided in said ball‘le portion 35 and conforming in shape to and ?tting the tube l6. Theportion 35 substantially ?ts the enclosure 3| slightly above the lower edges of the. plate portions 25 and 26.‘ The ba?le 35 has up-turned ?ange ‘portions 31 and 38 at the ends‘ thereof engaging the end The structure embodying my invention allows the'use of a poorer grade of kerosene without causing smoking, and permits of the use of signal lanterns for heavy signaling, involving jarring and sudden movement. and stoppage of movement of the lantern without causing ?ickering or ex tinguishing of the ?ame. ' ' In the operation of the lamp the ?ame spreader 2| including the bail‘le 34 serves as an automatic control for maintaining the ?ame at the desired height and preventing the drawing up or ?icker ing of the ?ame liable to occur when strong up draft currents develop as the lamp heats up. I obviate updraft currents by the construction em bodying the present invention. 15 ' The ba?lermember 34 also serves to reinforce the enclosure 3| internally, and to anchor the same to the wick tube l6 at the upper end thereof, thereby forming a strong, rigid and durable structure. 20 I Having’ thus described my invention, what I claim and desire to secure by Letters Patent is: v1. In a lamp burner, comprising a wick tube, a walls 30, the parts being secured together by suit ?ame spreader having upwardly and inwardly in-~ able means, such as the rivets 39. clined side walls and vertical end walls, a trans 25 verse partitionsurrounding said wick tube within said ?ame spreader and having lip-turned end portions engaging said end walls and secured The corner portions'of the ba?le plate 35 are up-turned, as indicated at 40, about longitudinally extending lines of bends 4| substantially in vertical align ment with the upper edges 32 of the portions 25 and'26, and provide four openings 42 through the baffle plate substantially at the four corners of the enclosure 3| for the passage of air to the burner. The air ~ currents passing vertically through the openings 42 at each side are directed inwardly towards each. other by the baffle por tions 46 and are discharged through the outlet openings 43 formed by the baille portions 40 and walls 25 and 26, the latter serving to deflect the incoming currents of primary air downwardly towards the ?ame as the jets of supplementary air induced through the openings 28 arecaused to unite and combine therewith. The opposite longitudinal edges of the baffle 35 are also pref erably recessed at 44 to provide central openings 45 at the inner sides of the de?ecting plates 25 and 26 for the introduction of additional air which is also de?ected inwardly and downwardly by the plates 25and 26 and subjected to the air jets. In my invention the ?ame is insulated against vertically ascending air currents by the imper forate barrier 35, all of the vertical openings 42 and 44 thereof .being outside of the downward vertical projection of the edges. of the mouth 33 of the enclosure 3|. The air currents are de ?ected inwardly and downwardly towards the ?ame at the ?at sides thereof by the de?ectors 25 and 26, while being acted upon by the air jets through the openings 28. The inwardly de ?ected air currents are concentrated by the ver ticalfba?‘le portions 46 upon the ?ame vertically below the reduced central portion of the ?aring mouth 33 to improve combustion and produce a bright, steady and intense ?ame. . thereto, said partition having up-turned portions at the corners thereof constituting baffles ar ranged substantially in vertical alignment with the upper edges of said inclined wall portions, and openings in said transverse partition between said ba?les and said inclined side walls. 2. In a lamp burner, comprising a wick tube, 35 a ?ame spreader including upwardly and inward ly inclined, ?at, perforated side walls and verti cal end walls, a transverse partition disposed about said wick tube at the lower end of said ?ame spreader and secured thereto, vertical par 40 titions on said transverse partition substantially in vertical alignment with the upper edges of said inclined walls at the ends thereof constituting baffles, and openings in said transverse partition between said vertical partitions and said inclined walls providing‘ a tortuous‘ path for the air sup 45 plied to said ?ame. ' 3. In a lamp burner, comprising a wick tube, a ?ame spreader including upwardly and in wardly inclined, perforated side, wall portions having convex upper edges, a transverse parti 50 tion disposed about the upper end of said wick tube in the lower portion of said ?ame spreader, openings in said partition at the corners and in termediate points of the margin thereof substan tially within the con?nes of the projection of said 55 inclined wall portions, and vertical partitions constituting baffles arranged in separated rela tion to eachother at the ends of said inclined wall portions for directing the air entering said corner openings inwardly towards the center of the 60 inclined wall portions.
