Be it known that I, GEORGE WAsHrNeToN, of Brooklyn, in the county of Kings and State of New York, have invented certain new and usefullmprovements in Hydrocarbon Incandescent Lamps;-.and I do hereby declare-the following to be a full, clear, and exact descrip- "mingling-chamber.
tion. of the invention, such aswill enable oth- I ers skilled in the art to whichit appertains to make anduse the same. I
My invention relates to an improvement in lamps; and it consists in an incandescent burner, a .commingling-chamb'er connected therewith, and a vaporizing-tube having one or more coils embracing the mantle, the said vaporizing-tube dlschargmg lnbO the com- My invention furtherconsists in anincandescentburner provided at one slde'with a commingling-chamber and a vaporizingtube having one or more coils which encircle the mantle.
My invention further consists-in the parts and combinations ofparts, as will be more fully described, and pointed out intheclaims."
The accompanying drawlng 1s a-view in elesection, of my lm'proved sage-way for the free passage of oil tothe' commingling-tubeB, which latter is connect-I The ed at its lower end to the coupling. burner A is also carried by the coupling B and. the commingling tube or chamber E thereof is located in a position to receive the vapor discharged from the vaporizing-tube. The upper portion of the tube B is bent at right angles to the vertical stem of the tube and formed into one or more coils B, which latter are designed to rest outside of and in close proximity to the mantle. This coil or coils B normally rests in a plane between the top;
of the mantle and the burner; but from experience I have found that probably the best results are attained by locating the coils slightly above theburner, so as to come within the fieldof"the flame. The discharging end of the vaporizing-tube is provided with a downwardly projecting ejector nozzle 6,
which latter passes through an'opening in cap d of the commingling-chamber' E and disf-o'har'ges the vapor directly onto the latter.
This commingling chamber is preferably in the form of a cylinder approximately the length of theburner A and in open communication at its lowerend with the burner.
The burner and its attached comminglingchamber and vaporizing-tube are removably supported on or carried by the coupling B and the tube and burner areheld against displacement by the set-screw f, carried in the stud a and engaging the tube, the stud being fixed to the burner and slotted, as described,
. Y Secured to the burner,near the centerthere: of,is the upwardly-projecting mantle-support to receive the tube B.
F. The mantle J, which is suspended from this supportyrests within the coil or coils of the vaporizing-tube. Hence when the mantle is heated bythe burning vapor and air the coil or coils become heated and rapidly vapor:
ize the oil and retains the vapor in a'heateol condition until it is discharged into the commln'gllng chamber. This comminglingchamingress'of air, and the latter is drawn into the chamber by the injector action of the vaporjet and is thoroughly commingled with the vapor. The discharge of vapor from the vaporizing-tube into the commingling-chamber is regulated and controlled by the needle-' valve G, which latter passes upwardly through a stuffing-box g in the lower end of the cham- .ber and rests with its tapering end within the outlet-opening of the vaporizing-tube. The valve can be screw-threaded for moving it longitudinally or it can be actuatedby a lever o'rother suitable device,
The mantle-support F is attached centrally to the burner and operates to support the mantle in position over the burner and within the coil or coils of the vaporizing-tube.
I is the starting-cup secured to the burner embracing or surrounding'the burner. This ber Eis provided with an opening 6 for the V cup is designed to contain suflicient alcohol or oil which when ignited produces sufficient heat to vaporize the oil in the vaporizing-tube adjacent thereto. The vapor thus generated rises in the tube and passing around the coils is discharged from the ejector-nozzle 0 downwardly into the commingling-chamber, and acting as an injector draws in air from the outside, through opening 0. The air thus drawn in mixes with the vapor and passes into the burner, and as it issues from the latter is ignited by the burning alcohol in the starting-cup.
The oil can be fed to the vaporizer-tube by "gravity or air or other pressure, and the intensity of the light can be regulated by increasing or lessening the supply of vapor to the burner. The light may be extinguished by closing the opening in the ejector-nozzle by the valve G or it can be extinguished by cutting off the supply of oil by turning a cock located in the oil-supply pipe.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a hydrocarbon incandescent lamp, the combination with a burner, and a commingling-ehamber approximately parallel with the burner and discharging into the latter, of a coupling having means for its attachment to a suitable base or support and supporting the burner and its commingling-chamber and provided with an oil-duct, and a vaporizing-tube leading from the egress end of said duct to the commingling-chamber and located within the heating zone of the burner.
2. In a hydrocarbon incandescent lamp, the combination With a burner, and a commingling-chamber approximately parallel with the burner and discharging into the latter, of a coupling having means for its attachment to a suitable base or support and supporting the burner and its commingling-chamber, and provided with an oil-duct, and a vaporizing-tube leading from the egress end of said duct to the commingling-chamber and provided intermediate its ends with a coiled section the latter being located within the heating zone of the burner.
3. In a hydrocarbon incandescent lamp, the combination with a burner, a commingling-chamber communicating therewith and a starting-cup adjacent to the burner, of a vaporizing-tube comprising two straight sections, both of which are within the heating zone of the mantle, one of said straight sections discharging the vapor into the commingling-chamber and an intermediate coiled section, the coiled section being located over the starting-cup and burner, and shaped to receive and surround the mantle, and a mantle-support carried by the burner, substantially as set forth.
4. In a hydrocarbon incandescent lamp, the combination with a removable vaporizingtube comprising a straight section and a coil at right angles to said straight section the said coil adapted to surround an incandescent mantle, of an incandescent burner a commingling-chamber located in line with the vapordischarge orifice in the vaporizing-tube and a needle-valve in the commingling-cliamber for closing such orifice.
5. In a hydrocarbon incandescent lamp, the combination with a burner, and a commingling-tube in communication therewith, of a vaporizer-tube comprising two straight members and an intermediate coil, both straight members and the coil being within the heating zone of the burner, and one of said straight members of the vaporizer-tube discharging into the commingling-chamber and a bracket supporting said burner and having an oil-suppl y duct leading to the other straight member of the vaporizing-tube.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
