Specification of Letters Patent.
Patented July 26, 1921.
Application filed November 29, 1920. Serial No. 427,015.
To all whom it may concern:
Be it known that LGnRoNrMo Cnosn'rrr,
citizen of the Republic of Argentina, resid-- ing at 3060 Oramer street, Buenos Aires, Republic of Argentina, have invented certain new and useful Improvements in Lamps, of whichthe following is a specification.
This invention relates to an improved lamp for "the production of heat and light, and has for its object theprovision of a lamp adapted to burn liquid fuel, such as kerosene, naphtha, orthe like, wherein no wick submerged in the li uid fuel is used and in which the said fuel rises by capillarity to the burner nozzle through a tubular chamber formed between two concentric bodies.
In the practical form of construction of the lamp, a pin or core is inserted into the bore of a tube, leaving between both parts a narrow tubular chamber, means being provided for the admission of the liquid fuel at the bottom of such chamber. At the top of said chamberis placed a fiat strip of as bestos or other porous, permeable and incombustible material which becomes saturated with the fuel and which, after being ignited, produces light and heat.
The liquid rises by capillarity within the aforesaid tubularchamber and is thus fed without interruption to the piece of asbestos until the same has entirely been consumed. The liquid fuel as well as the lower part of the tube and core are inclosed within a container of suitable form and material.
Kerosene and naphtha burning lamps, as well as alcohol lamps are well known, but
all these lamps comprise a wick holder and a cotton wick submerged within the liquid fuel which rises therein to the burner by capillarity. This arrangement however, is
open to several objections for instance, the wick will harden in time and thus interfere with therise of the liquid, besides roducing an insufiicient amount of light an head, its upper part burns away; moreover, the operation of such burners generally causes a disagreeable smell.
By causing theliquid'to rise by capillary action through the annular chamber be-\ tween the core and the tube until reaching the piece of asbestos fitted in the upper end of the tube and supported partly thereby and partly upon the upper end of the core, a perfect flame is obtained, as well as a carbureted combustion, without any smell.
The piece of asbestos may be placed in posltlon or withdrawn, at will and without any d1fliculty,thereby dispensing with the use of a burner, or wick holder, cotton wicks and the mechanical devices required for operatlng or adjusting the wick. In connection with the lamp constructed 1n accordance with this invention and for the purpose of regulating the flame, any suitable or desired means may be employed, such as a telescopingouter sleeve applied to the capillary tube which, on being raised, will decrease the light and heating power of the lamp, while increasing the same when being lowered, as will readily be understood.
The lamp according to this invention may be used for several purposes, as for lighting, with or without a shade, or for generating heat in connection with stoves or kitchen ranges, to which end the device 'will be arranged within a suitable frame.
In order that the invention may readily be understood and carried into practice without difficulty, two ofthe preferred embodiments of the same have, been illustrated in the accompanying drawings, wherein:
Figures 1 to 6 show an embodiment of the improved lamp, preferably for use as light producer, Fig. 1 being a side elevation, Fig. 2 a central vertical section and Fig. 3 a central vertical section of the container; Fig. 4 is a view showing the bottom member of said container, with the pin secured thereto, the container member appearing in section; Fig. 5 is a side elevation of the shade and Fig. 6, finally, shows a central section of the fuel drawing device and of the means for adjusting the flame.
In Figs. 7 to 11 a modified construction of lamp in accordance with this invention is shown, Fig. 7 being a side elevation of the complete lamp; Fig. 8 shows a central vertical section of the same; Fig. 9 illustrates a detail of the flame regulating sleeve; Fig. 10 is an elevation of the capillary tube with the means for adjusting the sleeve, and Fig. 11, finally, is a perspective view of the piece of asbestos.
Referring now to the first embodiment shown in Figs. 1 to 6, cl indicates the container which may be of any suitable material, rovided with a plain bottom 0 having a serles of recesses f, f, ffladapted to serve as feet. At the center of said bottom is affixed by soldering or otherwise, as indicated at a", the lower end of a vertical core in the form of a pin a, over which is telescoped a cylindrical tube 6, said pin or core and tube being. made of metal and being spaced from each other to produce an intermediate tubular chamber which communicates at its lower end with the interior of the chamber. The tube bis provided at its upper portion with a conical metal plug it, soldered at the inside to the surface of the tube; said plug fits in.
the conical ring 2', secured-by solder inside to the surface of the container at 2', whereby 7 ed by a sleeve m,.for'the purpose of increasing or decreasing the heat or light produced by the lamp, which may be done .by turning the said sleeve by means of its flange m. The sleeve'm is provided with a projection or finger m which bears on the inclined or cam surface of the plug it, the sleeve m describing, when rotatated, a helically ascending movement, as will readily be understood. By raising the sleeve m, the flame Wlll be reduced, and when lowering the same, the
opposite will take place. i The plug in order to enable the inner surface of the h and tube 72 may be withdrawn tube 6 to be thoroughly cleaned, as well as the outer surface of the pin a, thereby avoiding any interference with the free capillary rise of the liquid fuel. The conical orifice will thus have been opened at i, and the liquid fuel may be.introduced through the same. After charging the container d, the plug 72, and tube 6 are again placed in position; The liquid will rise by capillary action throughthe tubular chamber between the said tube 6 and the pin 0. and arrive at the piece of asbestos which willabsorb the necessary amount; and after being ignited,
the said piece of asbestos will continually be fed with fuel until all of the liquid contained within the receptacle d has been consumed. The container at is suitably fastened at its bottom to the member 0, and is also provided with a suitable handle to facilitate handling of the lamp; 1 If desired, the'lamp may be provided with a shade g, to which is aflixed a ping, rolled or Wound at one of its ends so as to form a handle and extended at 9 at the other end,
for insertion in a small tube]: soldered to the-container.
In the modified construction shown in "Figs. 7 to 11', the capillary tube, its'pin or core, the chamber between the tube and'core, the iece of asbestos and the means for adjusting the flame, are all of rectangular shape in cross section, instead of being cylindrical as in Figs. 1 to 6. Besides, the flame ad usting tube is operated 1n this case by means of a rack and a pinion, as will later be described. 7' indicates the capillary pin or core, of rectangular cross section, soldered at r" to the bottom of the container destined to hold the liquid fuel; and on the said core is telescopcd a tube of rectangular section on top of both of which parts is supported the piece of asbestos it, also of rectangular shape. 7t is the sleeve for adjusting the flame, of rectangular section, placed outside the tube Q and having secured to one of its sides a rack n. This rack engages with a toothed pinion n secured to the axle a, mounted in bearings 22 and p formed. in the arms of a forked bracket 72 which is soldered or otherwise secured at its lower end at q to the adjacent side of the capillary tube on one end of said axle is mounted an operating disk 0, as clearly shown in the drawings. .5 indicates the cap of the coutainer and s is a locking or safety ring, to prevent leakage or fire.
It will be understood that, the operation of this lamp is similar to that described in connection with the former embodiment, so that a detailed description thereof is deemed unnecessary.
