VAPOR BURNER.
Application led December rlhis invention relates to certain improvements in a vapor burner, designed primarily for illuminating purposes, and refers more particularly to burners of the kind which use a volatile liquid fuel the vapors of which are combustible, when united with air in proper amount, to produce a flame of in* tense heat.
The present improvements include means by which the burner may be readily pre-- heated with a small flame, as from a match, whereby to promote vaporization of the fuel preliminary to lighting of the burner. This and other objects of my invention, which will more fully hereinafter appear, are set forth in the accompanying description and drawings wherein I have illustrated a preferred embodiment thereof in the manner following:
Figure 1 is a view in elevation of a lamp equipped with the present burner with the shade therefor appearing in section;
Fig. 2 is an enlarged transverse section on line 2-2 of Fig. 1; and
Fig. 3 is a detail in vertical section, taken on line 3-3 of Fig. 4.
I would have it understood that the improved features herein set forth are appli-- cable generally to vapor burners, without special regard to the particular lamp or lantern structure with which they are incorporated. For purposes of exempliiication, a. lamp such as is shown in Fig. 1 may conveniently be referred to. It comprises a hollow base constituting a font for the reception of a volatile liquid fuel such, for example, as gasoline or kerosene. It maybe provided, as is usual, with a plug l1 which provides a closure for the filling opening. Extendingl upwardly from the font is a tube 12 which, if desired, may be surrounded by a handle 13 by which the entire lamp may be conveniently moved about Connected to the upper end of the tube 12 is a T-fitting 15 having therein a needle valve which includes a screw stem 16 operatable by a knurled wheel 17. A generating tube 24 which extends upwardly from the fitting is connected thereto in any suitable 50 manner as by a coupling nut 25.
At its upper end the generating tube communicates with a mixing chamber with which connects a depending air pipe 31 the lower end of which is secured to a base plate 32 laterally extending from the fitting 15.
7, 1925. Serial No. 73,756.
By this means the air pipe serves as a sup` portrfor the burner and the several parts which are carried thereby. Included in the burner structure is an upwardly extending pipe 33 which connects with a manifold 341s from which leads downwardly a pair of depending tubes 35 each adapted to support at its lower extremity an incandescent mantle 36. To complete the illustrative lamp structure, a head 37 supported on the manifold serves as a mounting whereon to carry a shade 38. Such structural details, however, form no partof my invention, but are merely shown as appropriate to complete the lamp which is illustrated in Fig. 1. y
Carried by the generator tube at a desired point between its ends, is a flue 40 of special formation. As shown, it consists of sheet metal, preferably copper, or a copper alloy, having incisions which permit certain portions thereof to be inwardly bent in the form of straps lll. The remaining proximate portions constitute outer straps 4-2 (see Fig. 3). Elsewhere the flue walls are bent around as at 43 to embrace the generating tube upon opposite sides thereof. As shown, the embracing edges of the flue approach each other closely upon the rea-r side of the generating' tube. rIhe space intervening between these edges may be filled, as at 441-, with a solder of silver. rlhe flue is adhered to the generating tube preferably by brazing, so as to obtain a maximum heat conducting connection therewith.
At the time the present burner is to be started, the flame of a match, or other small combustible article, may be applied to the one side of the generating` tube just below the flue thereon. The flame will impinge against the lower edges of the inner' and outer straps t1 and 4t2; it will also come in contact with the generating tube behind the inner straps 41, but not elsewhere. The heat so applied to the strap edges will be conducted quickly by these straps to the two sides and rear portion of the generating tube, whereby the entire tube periphery will be heated at once. 'I'he result of this is to raise the temperature within the tube in a short space of time sufficiently to promote vaporization of the fuel whereby the burner may be readily ignited.
I would have it noted that the flue just described is of advantage in that it permits a flame to impinge directly against one side of the generating tube; at the saniel tiine a considerable extent of flue edge surface is iinpinged by the flarne so as to transfer heat through the conducting` Walls of the fine to the generating tube upon the sides and rear portion thereof. The solder between the two heating edges ofthe flue conducts this heat across the gap whereby the heat is circuinferentially distributed. Y
Itis manifest, of course, that the exact forni and shape of this flue inay be inodiied in various Ways, but inasmuch asa inatch flame inay be applied to the leenerating tube only upon one side tliereeriy the illustrative Y structure is typical of one einboruinent which will very satisfactorily perform the intended purposes of this invention.
