The chambers 10 and 1-1 are embodied in the lower section "6, and the chamber 12 Yisjlocated inthe upper section 7. Thewater v chamberIlO is materially larger than the remainiugchamhers l1 and l2lan'd the chamber is-reduced in vertical extent so as to confine thevdry'steam therein and conserve thepressure of said steam. The upper sec-' tion 7:11:15 atop plate or covering 13 formed at regular intervals with. a r plurality of openorganization embodyingthe features of the ings 14E surrounded by internally vscrevvthreadedcollars .15, the openings-1 L and collane 15; being sdisposed at regular intervals and; .in ,syinmetrical positions over the top 4 plate 13. 1 The bottom 16 of the chamber 12 also has a plurality of openings 17 formedtherein surrounded by collars 20, and below the latter openings and collars the bottom plate 16 of the chamber 12 has two openings 21 therein and also surrounded by collars 22 projecting upwardly into the chamber a suitable distance above the bottom f plate 16. Connected to the front end 23 of the chamber by means of suitable collars 24 and connecting devices 25 and opening into the said'chamber are vertically disposed wet steam conveying pipes 26 having rearwardly extending conveying pipes 27 of smaller diameter and connected to the upper ends'the-reof by suitable connecting devices 28 and continuing in the form of further diametrically reduced pipes 29 and 30, respectively extending forward and rearward in looped form and united by connecting devices 31 and 32. The rearends of the rearwardly extending reduced pipes 30 are united by connecting devices 33 to vertically disposed branch pipes 34fextending through the openings 19 within the collars 20 and secured in the openings 21 within the collars 22 and fully opening into the upper portion of the dry steam chamber 11. The vertical branch pipes 34 are imperforate and as shown by Fig. 3 pass through the oil chamber 12. I

As shown by Fig. 2, an oil supply pipe ,35 is "connected with and opens into the chamber 12. To the lower portions of the unions 25 a water supply pipe 36 is connected and the oil supply pipe 35 and water supply pipe 36 are also connected to the bottoms of oil and water supply reservoirs 37 and 38, the pipes 35 and 36 having valves 39 and 40, for regulating or cutting ofit the flow of the oil and water from the reservoirs 37 and 38 as may be found necessary. The oil and water reservoirs 37 and 38 are adapted to be located any suitable distance from the improved burner organization and each has a central rod 39 disposed therein for operation therewith of a float 40, the float being fixed to the rod and the latter vertically movable in suitable guide devices as, for instance, a bracket arm 41 as shown in the reservoir 38, and lower guides 42 at the bottom of each of the reservoirs, it being understood that the bracket arm 41 may be duplicated in the reservoir 37. On each rod are a pair of collars 43 between which the inner end of a lever 44 is mounted and intermediately fulcrumed on an. ear or lug 45 projecting from a supply valve casing 46 having a discharge outlet 47 and a springactuated valve stem 48 risingfrom the top thereof and formed with a rounded head 49 on Whic'hthe free end of the lever 44 has bearing. The valve within the casing 46 may be of any suitable type, such, for instance, as a vertically movable plug valve, and connected to one side of the supply valve 46 is a supply pipe 50, which projects outwardly through the side of the reservoir. This construction is also duplicated in the reservoir 38, the rod 39 in the latter reservoir being shorter than t-he said rod in the reservoir 37 in view of the different horizontal locations of the two chambers 10 and 12 with which the respective reservoirs 38 and 37 are connected. The supply pipes extending outwardly from the supply valves 46 will be respectively connected to a suitable oil and water supply and it will be seen that the level of the water and oil in the reservoirs 38 and 37 is the same as the level of the water and oil in the chambers 10 and 11, as indicated by dotted lines'in "Figs. 2 and 3 and also partially infull lines in the latter figures. It is intended. that the predetermined level of the water and oil in the chambers 10 and 12 be uniformly maintained through the automatic operation of the float and supply valve mechanism in the reservoirs 38 and 37. The reservoirs 37 and 38 are also preferably closely arranged as shown by Fig. 2 and may be one structure divided by a central partition. However, the exact manner of forming these reservoirs and positioning the same may 'be varied at will, and also the automatically operating means therein for ma'intaininga uniform level ofthe water and oil in the chambers 10 and 12. As shown, the reservoirs 37 and 38 have a common top cover orplate 51, and it will ,be further understood that the pipes 35 and 36 connected to the bottom portions of these reservoirs will be of any length desired and have a general contour that may benecessary in making connection with the chambers 10 and 12.

Below the bottom of the water chamber 10 an oil conveying pipe 52 is disposed and transversely looped or. bent as illustrated by Flg. 1, to increase'the circulation of the oil or cause the latter to have as long a conveyance as possible beneath the water chamber and at the rear end of the burner organization this pipe 52 is continued in the form of a vertical branch 53 a suitable distance above the top of the plane of the oil chamber 12 and then regularly projected for wardly andrearwardly in the "form of vaporizing loops 54, the uppermost loop being continued forwardly a greater distance than the loop below and connected to a vertical pipe 55, which opens through the top 56 of a regulator 57 This regulator and the looped pipes 54 may or may not be used, as desired, in view of the factthat the conthat are omitted in more simplified instal-i latlons. It may also be found necessary in some-installations to dispense with the oper-- ation of the vaporizing coil 54, its connection 53 and the conveying .pipe 52, and if such be the case, the supply of oil may be' shut off from the conveying pipe through thegmediumrof a valve59' located adjacent to the union 58. 1 The regulator 57v may also be of any preferred type, but one practical form thereof is shown by Fig. 3 and consists of :an outer casing or shell 60 having a lower rounded bottom'6 l and therein is fitted a valve case 62 of lessdiameter than the shell,

said valve case. having a screw-threaded:connection; asat 63, with the upper portion or the case or shell 60 and provided with a horizontal flange 64, which rests on the upper edge of the casing or shell 60 and to which'the topplate or cover 56iis secured. Withinthe valve casing 62 a hollow valve 65 is rotatably mounted and is secured to a stem 66 having bearing in" the lower end of the" casing 62 and "extending upwardly through a suitable bearing or collar 67 in the top portion of the valve 65 and also through an'opening68 in the top or cover plate 56. "The top or cover plate56 is projected any suitable distance towards the 7 front in the form of an indicating segment 69 having opposite stop flanges-70 at the ends'thereofand onits upper surface inscribed with characterswhich in the present instance consist of a cipher (0) and the 'nu' m'erals l, 2, 3 and 4. Cooperating with this indicating segment and the characters thereon is a horizontally disposed valve lever71 attached at its inner extremity to the upper end of the valve stem 66. The casing or shell 60 at its rear-portionhas a union 72 projecting rearwardly therefrom for connec-- tion of a pipe 73, which has its rear endin engagement with a collar or union 74 in the central portion of the front end of the chamber 12. The opening through the rear portion of the union is reduced; as at 75, and

is wholly above the maximum level of the,

oil in the chamber 12, as shown by the dotted lines. 'Through the 'adjacent walls of theinner valve casing '62 and valve 65 are ports 76 and 77, the port 76, always'standthe port 70. When the'valve 65 is turned to certain positions,i,the ports 77 1 and 7 6 will be varied as to the opening, space pro-i vided by the same relatively to the opening or .port 75. An annularspaceror chamber 78 is formed between the valve casing 62 mg in alinement with the inner terminal of' and the outer valve casing or shell 60, and this annular space is continuous with a lower chamber 79 between the bottom of the inner valve casing 62 and the outer casing or shell 60. Connected to the lower portion .of the chamber 79 is a dry steam pipe 80,

which as shown by Fig. l'projects laterally andjis'continued by an angular branch 81, which in turn is secured to a cross return branch 82,connected to the unions 32 of the reduced dry steam forming pipes 29 and regulate'the quantity of the dry steam passing'through the bottom of the regulator 57 or into the chamber 79, or the supply of steam may be entirely out oifwhen the regulator is not in use. The valve 65, as hereinbefore indicated, may be adjusted to regulat'ethe size of the openings between the registering'ports 76 and 77 to entirely close off any registration, of these ports,-and the indicating characters on the segment 69 will give correct information as to the adjustment. When the lever 71-is turned fully over the cipher (0), the valy e 65 will be closed, or the port 77 thereof will not register with the port 76. When the lever 77 is turned to register with the numerals 1, 12 and 3, the ports 76 and 77 will be opened, respectively, one-fourth, one-half and threefourths, and when the said lever is turned fully'over to register with the numeral 4, the ports 7 6and 77 will have full registration, or be-completely open.

At regular intervals over the upper portion of the body or main element 5 a plurality of burner units 84 are disposed and each unit consists of an outer shell 85 having an upper round or semicircular top '86 with perforations 87 formed therein The lower extremity of the shell 85 has an integral stop collar 88 and exterior screw threads 89, which, are adapted to separably engage the threaded collar 15 around the opening 14 and rising from the top plate or covering 13 of the oil chamber 12. The lower end 'of the shell 85 terminates coin'cidently with, the lowerside of the top cover or plate 13, as clearly shown by Fig; 3, and the said shell is of equal diameter throughout its extent.- Within the shell 85 is a shell 90, of less diameter but of essentially the same contour,to produce an annular chamber 91 between the two-shells, the upper rounded or semicircular end eaof the inner shell being. formed with perforations or openings '93. The lower portion of the inner shell .is diametrically reduced and provides a chamber 12 and the dry steam chamber 11,

as the neck 94: of the inner shell 90' is imperforate. The annular chamber 91 between the two shells and 90, however, is fully open at its lower. terminal through the oil chamber 12, and by this means the oil vapor is permitted to unrestrictedly pass upwardly between the two shells and the dry steam from the chamber 11 is free to pass upwardly into the inner shell, the dry steam and oil vapor mingling within the space between the upper semicircular ends or heads 86 and 92- of the-respective shells in proper proportions to form an advantageous combustible heating medium. The upper extremities of the burner units 8 1 stand above the adjacent pipes and these units as a whole will provide for an intense heating action within a furnace chamber for both domestic and general commercial usage. The shells 85 and 92 are readily removablefrom their respective collars 15 and 18 for cleaning purposes and to give access to the'chambers 12 and 11, and it will be understood that when necessary the said burner units may be replaced by similar new devices without affecting the remaining burner units that may still be in practical working order. The pipes 27, 29, 30 and the vaporizing loop 54: are located between portions of the burner units, and the heat from the latter affect the said pipes and vaporizing coil 'to effectively dry the steam and vaporize the oil when the vaporizing coil 54: is open for use.

Below the conveying oil pipe 52 supplemental burners 96 are horizontally disposed and consist of burner tubes 97 having a plurality of upper openings 98. The burner tubes 97 are closed at their rear ends by suitable caps 99 and connected at their front ends to a T-shaped supply or cross branch 100 having a supply pipe 101 adapted to be connected to a gas main and provided with a valve 102, by means of which the gas from the main may be cut off as hereinafter more fully explained. The T-shaped or cross supply branch 100 also has a cross vapor pipe 103 with two outlet branches 104: opening into the said T-shaped supply or cross branch adjacent to the outer ends of the burner tubes 97. The vapor pipe 103 is connected by a supply pipe 105 with the top portion of the union or connection 72 for the pipe 7 3, which establishes an open way between the front portion of the chamber 12 and the regulator 57, this regulator serving, as hereinbefore indicated, to admit an auxiliary vapor supply to the several burner units, or, specifically, to the lower portions of the annular chambers 91, to supplement the vapor produced in the chamber 12. The pipe 105 will operate as a supply means relatively to the vapor connection for the tubular burners 97 even though the valve 67 may be closed and the conveying pipe 52 cut off through the medium of the valve 59,

in view of the fact that the pipe 73 is open to the chamber 12 and vapor from this chamber may pass into the pipe 105. In starting the improved burner organization it is proposed to use ordinary from a street service admitted through the pipe 101 and to the burner tubes 97. By this means the burner organization will be thoroughly heated and steam formed as well as oil vaporized in the respective chambers 10 and 12 and pass through the courses hereinbefore explained and into the burner units in such proportions as to produce a combustible heating medium, and if desired the .burner tubes 97 may continue to act as heating means with fuel supplied from a gas main, but it is preferred that afterthe burner organization as a whole has been caused to operate for some time to automatically produce hydrocarbon vapors and dry steam, the valve 101 be closed and the hydrocarbon vapor be fed to the said burner tubes by means of the pipe 105 and cross vapor pipe 103. By this means it will be seen that the burner organization will supply a heating medium for the burner tubes 97 independently of any gas main, with economy in the heating operation;

As hereinbefore indicated, the simplified operation of the burner organization will be through the medium of the burner units 84 independent of the vaporizing coil 54, the oil conveying pipe 52 being then cut off by closing the valve 59 and thereby also eliminating the regulator 57 controlling the auxiliary or supplemental supply of hydrocarbon vapor and dry steam. This simplified operation will be sufficient for ordinary domestic use, or in small domestic heating furnaces. In larger installations such as steam boilers, locomotive and marine engines it will be preferred to use the vaporizing coil 54 with the conveying pipe 52 in connection therewith and also the regulator 57 controlling the auxiliary supply or supplemental mixture, as hereinbefore explained, and regulable through the adjustment of the lever 71 and valve 65. In some instances the simplified form of the burner organization will be used without the vaporizing coil 54 and connections therefor and the regulator 57, it only being necessary to close the openings where the several parts of this auxiliary attachment are connected by means of caps or screw plugs without in the least modifying the simple operation of the burner its w ich. will hen e eu plied wi hllytl ig e 'bfill:W9 39111 d elle I2; end'dry steamfronithe u h 1 p;
