SPECIFIQATION forming part of Letters Patent No. 760,672, dated May 24, 1904'. j

Be it known that I, GEORGE WASHINGTON, of 'Tompkinsvillm in the county of .Richmond and State of New York, have. invented certain K to make and use the saine.
My linvention relates to an improvement in hydrocarbon incandescent lamps, and is a division of application Serial No. 44,301, renewed January 22, 1901.
' My invention consists in the parts and combination of parts, as will be more fully explained, and pointed out in the claims.
1n the accompanying drawings, Figure 1 is a view in section of a lamp embodying my invention; and Fig..2 is a View, partly in section and partly in elevation, of a modication thereof. y y
1 represents a vaporizi-ng-tube provided at its lower end with a removable plug 2, having a central longitudinal opening for the passage of a needle N- valve, which latter is suitably packed to prevent the escapeof any oil. This vaporizing-tubeis supplied with oilgby any suitable means-as, for instance, by oil-pipe B-and is provided at its discharge end with nozzle 4, which latter has va tapering bore through which the needle 5 passes.
The upper end of the vaporizing-tube 1 .is secured to or made integral with the base 11,
which latter acts as a heat-accumulating body for heating the vaporizing-tube. Secured to the base 11 is the upwardly-projectingcom mingling-tube 12, into which the vapor is discharged, and surrounding the commingling or inner tube 12 is an outer longer burner-tube 13. In the construction shown in Fig. 1 the upper end of the commingling-tube 12 is open and the top ofthe burner-tube closed,A
and the latter is provided at a point between its ends with a plurality of burner-tubes 44, each of which is provided with a mantle. Instead, however, of attaching a plurality of burners to the tube 13 at a point between its 1898. Renewed January 22, 1901, Serial No. 441,301. 4Divided and this applicationfiledI Marel. 20, 1902.

ends it is evident that a plurality of burners can be connected near the top'of burner-tube and above the commingling-tube 12 as shown in Fig. 2.- In this construction vof lamp air-l v inlets 45, pass into the commingling-chamber through the base 11 at a point below the aux iliary heater and discharge the air adjacent to the discharge end of the vapor-nozzle, so lthat the airand vapor will be thoroughly intermixed in their passage through the comminglingstube. The vapor asfit issues .from the vapor-escape nozzle draws in air through the openings'45, and' the air andvapor thus brought together are co'rnmingled and pass upwardly. In the construction shown in Fig. l all of the mixed air and vapor is deflected by the closed top of the burner-tube and passes downwardly, while in Fig. 2 a part passes upwardlyto the burners y14 and a part down around the commingling-tube 12. In both instances, however, a part of the mixed air and vaporl passes down to the base 11, which `is provided with a series of jet-orifices 22, and the mixed air and vapor escaping through these orifices is burned in direct contact with the base, the flamesfrom the several jets iinpinging against the fianges 24, thus quickly heating the base and maintaining it atsuch a temperature as to quickly vaporize the oil withinthe upper portion of the vaporizingtube. The vaporization ofthe oil may be started by heating the generating-tube lin any manner; butI prefer to'provide it with a starting-cup designed to contain sufcient alcohol or oil Vfor the initial heating of the generating or vaporizing tube. After the vapor beginsto form it enters the burner-tube and filling same a part of itescapes through the vapor-escape orifices or 'auxiliary heater 22 and will be ignited by the flame from the starting-cup, and
as these jets impinge directly on the flange 24 of the base the latter will quickly be heated to a temperature sufficient tovcontinue the vaporization of the oil. Y'
It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention.
Hence I Would have it understood that I do not Wish to limit myself to the exact construction of parts shown and described; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination With a main burnertube, and a mixing or commingling chamber Within the same, of a jet-nozzle extending into the commingling chamber, means for discharging air into the eommingling-chamber, an auxiliary burner adjacent to the dischargenozzle and receiving its vapor from the main burner-tube, and a plurality of burner-tubes extending from said main burner-tube, substantially as described.
2. The combination with a comminglingchamber, means for discharging air into said chamber, a casing surrounding and inelosing the eommingling-chalnber, and a plurality of burners each directly connected with this casing, of a vaporizing-tube having its discharge end terminating Within the eomminglingchamber, and an auxiliary burner at the base of the casing and adjacent to the base of the commingling-chamber, for heating the discharge end of the vaporiZing-tube, substantially as set forth.
3. The combination with a comminglingchamber, means for discharging air into said chamber, a casing surrounding the chamber, and a plurality of burners each connected directly with the casing at points above the airinlet, of a vaporiZing-tnbe discharging into the commingling-chamber adjacent to the airinlet, and an auxiliary burner at the base of the casing for heating the discharge end of the vaporizing-tube, substantially as set forth.
4; The combination with a comininglingchamber, a casing surrounding same, means for discharging air into said comminglingchamber, and a plurality of main burners cach connected directly to said casing, of a vaporizing-tube discharging into the comming] i ngchamber adjacent to the egress ends of the air-inlets, and an auxiliary burner at the base of the casing and above the ingress ends of the air-inlets, the said auxiliary burner adapted to heat the discharge end of the Vaporizing-tube, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
