Description
(1) To all wh~om it Tnay concern:
(2) Be it known that I, *WILLIAMr C. COLE- Aa citizen of the United States, residin g at Wichita, in the county of Sedgwick and State of Kansas, have invented new and useful Improvements in Lamps, of which the following is a specification.
(3) The present invention relates to lamps of t1le typie in wbid the liquiid hydrocarbon is 0 first vaporized and is afterward mixed with air before burning, the flame being employed for making a mantle or like structure incandescent. In this type of lamp, it is advantageous, if not absolutely necessary, to have the vaporizing tube comparatively thin, and it is preferaly constructed of brass or similar metal. As a result, it becomes brittle when heated, and if the upper lamp structure is supported thereby, there is sonic dainger of thie tube breaking if the lamp should fall.
(4) It is therefore one of the primary objects of the present invention to provide supporting means for the upper elements of the lamp that will remove the weight of the same from the vaporizing tube. At the same time, a very compact structure is se- cured, by means of which the tube can be kept thoroughly heated.
(5) In the drawimngs :-Figure 1 is a vertical sectional view through a lamip, showing one cinbodlianent of (lie invention. Fig. 2 is a detail sectionmal viewv on an enlarged scale and subtantially on time line 2-2 of Fig. 1, andl Figs. 3, 4 and 5 are detail sectional views through other forms of structure.
(6) Similar reference numerals designate corresponding parts in all the figures of the drawings.
(7) Referring first to the embodiment disclosed in Figs. 1 and 2, a base font. 6 is em- ployed, from which extends a, vertical central support 7 constituting means for con- dueting the liquid fuel from the font 6 to the vaporizer. Threaded into, or otherwimse secured to the uipper eud of the pipe 7, is a head 8, hiavinig at pasrSageway 9 for~ the fuel, which passagewar leads to ail offset elbow 10 that is connected by a union 11 to the lower end of a vertical vaporizing tube 12.
(8) This vaporizing tube has a cap 13 on its upper end that carries an offset coupling 14 terminating in an internal valve seat 15, and connected to this coupling 14 is a headt 16 terminating in a depending vapor discharge nozzle 17. A controlling valve 18 is also mounted on the head 16, and cooperates with the valve seat 15 in a manner well understood, to regulate and cut off the passage of vapor from the tube 12 to the nozzle. Mlounted on the head 8 is a standard 19, the upper end of which carries an air and vapor mixing chamber 20, shown in section in Fig. 2.
(9) Said chamber has depending burners 21 that communicate with the upner portion there- of, as shown at 22, and said burners also constitute supports for inverted mantles 23, as is well understood to those skilled in the art. Extending downwardly through the top of the mixing chamber, and well toward ‘0 the lower portion thereof, is a Bunsen tube 24, the upper end of which engages in a coupling 25 having a nipple 26 at its upper end that detachably receives the nozzle 17. This coupling also has an outstanding tubular 2x- tension 27 constituting an air nuiet that is controlled by an adjustable cap 28. A guide sleeve 29 is preferably carried by the con- plinmg, and surrounds the vaporizing tube, said sleeve having threaded therein, a set screw 30, which, with the extension 27, constitutes a support for the metal ring 31, to which the shade 32 is connected in the well known manner. With this construction, it will be obvious that the comparatively heavyI sup~erstructure of the lamp is supported by the standard 19, and the vaporizing; tube is thus relieved of the weiiht. At the same time, time tube is maintained in proper rela- tion, particularly at its upper end, by means of the collar 29. Furthermore, it will be evident that the mechanism is exceedingly com- pact, and with the exception of the projecting parts to be manually operated, is entirely hidden by the shade and its hanger.
(10) It will also be seen that the operating means for thme valve is located outside the heat from the burners, as is also thme packing for said valve.
(11) In Fig. 3, a. slightly modified form of con- 00 strumction is shiown. In this embodiment, the fuel conducting pipe is designated 33, and carries a head 34 connuectecd by a union 35 withi the lower end of the vaporizing tube 36. This tube is disposed axially of the ipe 33. In this instance, the standard 37 is offset and is slidably mounted in anl extension 38 of the head, being normally held against its sliding movement by a set screw 39. The upper end of the standard carries a 0 mixing chamber 40, from one side of which are suspended depending burners 41 carry- ing, mantles 42, these burners being disposed on opposite sides of the vaporizing tube in a manner well understood. The upper end of the vaporizing tube 36 has an offset portion 43 carrying a depending nozzle 44, and the flow of the vapor to the nozzle is regulated by the usual valve 45. A coupling head 46 has a nipple that detachably receives the nozzle 44, and has an air inlet 47. It also has a depending Bunsen or air and vapor conducting tube 48 that extends through the top of the mixing chamiber 40, and depends within the same, as shown at 49. Said coupling furthermore has a bracing collar 50 that is slidable upon the vaporizing tube, and a pin or set screw 51, threaded into the collar, serv,-s, with the air inlet extension 47, . .s 52.
(12) Temdfcto illustrated in Fig. 4 is peculiarly adaptable for use with a single mantle, but it is not’ necessarily limited thereto. In this type of burner, the support or fuel conducting pipe is designated 53, and carries a head 54 having a passageway 55 for the hydrocarbon. This passageway is connected, through a union 56, to the lower end of the ‘-porizing tube 57. A standard 58 also car~ied by the head, is disposed alongside the tube 57 in parallel relation thereto. Connecting the upper ends of the tube 57 and standard 58, is a coupling 59 having a vapor discharge nozzle 60, arranged between the tube and standard, and a controlling valve 61 is located in this coupling. Slidably mounted on the standard and vaporizing tube, is another coupling 62 held in place by a set screw 63 threaded thereinto and engaging the standard. This coupling has an upper nipple 64 that detachably receives ilie nozzle 60, and is also provided wvith an air inlet 65. An air and vapor mixing or Bunsen tube 66 depends from the coupling, and carries at its lower end a burner over which the mantle 67 is mounted.
(13) Referring now to Fig. 5, still another embodiment of the invention is disclosed. In this form, the upper end of the support or fuel-conducting pipe is designated 68, and carries a head 69, from which~ extends the vaporizing tube 70 and a standard 71. The upper erd of this vaporizing tube is provided with an offset coupling 72 containing a controlling valve 73 and having a depending ,discharge nozzle 74 that detachably communicates with the upper end of a coupling 75 having an air inlet 76 and an arm 77 provided with a guide collar 78 that is slidable on the vaporizing tube. This coupling furthermore carries a depending Buln- sen or air and mixing conducting tube 79 that delivers into the lower portion of a mixing chamber 80 mounted on the upper end of the standard 71. The mixing chain- ber is provided wiith one or more burners 81, from which are suspended the usual mantles.
(14) It will ha clear that all of these structures involve the same general principle of construction, aid have the same advantageous features, in that the parts are suip- ported separately’ from the vaporizing tube, so that said tubs can be made smaller and of light gage. They are all compaet and the parts are entirely accessible for the purpose of cleansing and repair.
(15) 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, wpith- out further description, and it will be understood that various changes in the size, shape, prorlion and minor details of con- struction, may be resorted to without departing from the spirit or sacrificing any of the advanitages of the invention.
