JOHN C. HEINRITZ AND JAMES WATSON MCCUEN, OF BALTIMOR, MARYLAND.
INCANDESCENT VAPOR-BURNER.
SPECIFICATION forming part of Letters Patent No. 671,884, dated April 9, 1901.
Application filed November 23, 1900. Serial No. 37,508. v\l\lo model.)
To a/ZZ whom, t may concern:
Be it known that we, JOHN C. HEINEITZ and J AMES WATSON MCCUEN, citizens of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Incandescent Vapor- Burners, of which the following is a specification.
For incandescent Vvapor-burners wherein the Vapor is generated as it is consumed by the heat of the burner-flame We have designed a novel construction of burner-head whereby the vaporizing-heat is furnished and maintained, and the precise improvement therein will be set out in the claims hereto appended, in connection with the accompanying drawings, in Which- Figure l is a vertical section of a vaporlamp embodying our improvement. Fig. 2 is a like section taken through the vaporsupply pipe. Fig. 3 is a vertical section showing the solid burner-head and the vapor-mixing tube. Fig. 4 is a horizontal section of the solid burner-head. Fig. 5 is a Vertical section of the same.
The several sectional views show a central chamber in the solid burner-head and its communication with the mixing-tube tor supplying the jet-dames.
A solid head l comprises the burner-body and has the burner-forming part 2, within the chamber 3 of which the combustion of the vapor takes place. The burner has the usual foraminous cap, through which the combustible vapor passes to the mantle. The solid burner-head has a central bore which passes through and within which the upper open end of the mixing-tube 6 is shrunk and from which it depends. At one side of the mixing-tube the burner-head has a bore opening on its under side and Within which the vaporsupply pipe l5 is secured and from which it depends and terminates `in a Valved opening centrally with and below the vapor-mixing tube. A bore is made in one side of the solid burner-head near its bottom, into which is secured the oil-supply 11, which is supplied from an elevated reservoir (not shown) in the usual manner. The provision for rendering effective and maintaining the iiameis formed within this solid head, so as to connect with and supply the vapor from the oil-supply pipe. The generator for the Vapor is formed by the duct 12, leading from the oil-supply pipe 11 to the top part of the head, thence by the horizontal duct 13, extending across the head just beneath its top surface, and by the duct 14, terminating in the open end of the vapor-supply pipe, Fig. 2. Within the center of the headis an annular cham ber 5 around the vapor-mixingtu be, which by perforations 6 in its sides has communication with said chamber as in Fig. 5. From this inclosed central chamber extend ducts 8, Fig. 4, which open at the top ot the solid head. Overhanging the openings 9 of thesevapor-jet ducts is a rim l0, formed around the burner-chamber 3, so that when the vapor-j ets iss uiug from these ducts are ignited the flame therefrom will on striking the rim be deected down upon the top of the solid head, heating it and the generator-ductstherein. Withinaudthrough these duct-heads l2 and 13 the oil passes from the supply-pipe ll and is vaporized by the heat of the burner-head.
The ordinary needle-valve 16 controls the tlow of the vapor into the mixing-tube from 'which the burner is supplied.
A shield 4 depends from the burner-head, incloses the valve-controlled Vapor-supply pipe and the mixing-tube, and has perforations 17 for the admission ot` air for mixing with the vapor. The bottom of this shield may also be perforated. A perforated curb 18 19 incloses the solid burner-head and its jet-ames as a housing protection for the jetlames and for the heated head and for affording ventilation to that portion of the mantle which incloses the burner. This curb supports the mounting-stem 2O for the mantle.
The initial heating of the solid burner-head may be by Lorch for starting the vaporization of the oil in the ducts -and for filling the valved vapor-supplying pipe when the Valve is opened, and the Vapor passing out is mixed with air in the mixing-tube, from which it passes to the burner.
The provision of the chamber inclosed in the solid head and having communication with the mixing-tube by the holes 6 in the walls of the latter thereby makes said chamber a reservoir always filled with vapor and IOO uniformly supplies the jet-Haines, whereby the degree of heat is rendered constantly effective for vaporizing the oil to produce a suicient and constant supply of vapor and to supply it in a highly-heated condition to the mantle. In a burner of this kind the important matter is to maintain a constantlyuniform heat in order to produce a constantly-uniform volume of vapor and therebya constantlyl uniform or steady ame to heat the mantle to a uniform incandescence. For this the solid burner-head once heated keeps its heat to a high degree.
Obviously the upward draft and pressure of the combustible mixture within and through the mixing-tube will cause a constant flow of the vapor through the openings 6 into the inclosed chamber 5, and thus constantly supply and force the vapor from this chamber up through the ducts in the solid head to supply the jet-flames, while the solidity 0f the head and the fixing of the mixing-tube, the vapor' supply pipe, and the oil-supply pipe directly therein gives eciency for maintaining a high vaporizing heat in the head.
To facilitate the initial heating of the solid burner-head by the torch, the bottom of the shield may be made removable and the bottom of the burner-head formed vwith a central cavity, so as to concentrate the heat. A
convenient way of forming the holes in the mixing-tube, so that they will register with the inclosed vapor-chamber, is to drill a hole 7 l. In a vapor-burner, a burner-head having a central opening, a recessed chamber, a rim, ducts leading from the chamber having their openings adjacent the rim, and vaporizingpassages, a mixing-tube arranged in the central opening of the burner-head, passing through and closing the chamber and having perforations leading into said chamber Whereby a reservoir is formed around the walls of the mixing-tube for supplying said ducts.
' 2. In a vapor-burner, aburner-head having a central opening, a recessed chamber, a rim, ducts leading from the chamber and terminating beneath they rim, and vaporizing-passages, -a mixingtube arranged in the central opening of the burner and closing the ch-amber said tube having wall-perforations below its upper end leading into said chamber around the walls of the mixing-tube.
In testimony whereof we affix our signatures in presence of two witnesses.
