UNITED STATES PATENT OFFICE...
EMIL IIEINRIOl-I CONRAD OEI'ILMANN, OF BERLIN, GERMANY.
INCANDESCENT-LIG HT BURNER.
SPECIFICATION forming part of Letters Patent No. 558,204, dated April 14, 1896. Application filed July 17, 1895. Serial No. 556,276. (No model.)
To aZZ whom it may concern:
Be it known that I, EMIL HEINRICH CON- RAD OEHLMANN, engineer, a subject of the King of Prussia, German Emperor, residing at the city of Berlin, Kingdom of Prussia, Germany, have invented certain new and usef ul Improvements in and Connected with Incandescent-Light Burners, of which the following is a specification.
The present improvements in burners for incandescent lights relate in the first place to the overheating of the mixture of gas and air in the chamber, and in the second place to the apparatus which facilitates the outlet of the gases generated at the burner from vola tile fluids into the mixing-chamber.
In the accompanying drawings I have illustrated as an instance a spirit-lamp for incandescent light embodying the invention.
Figure 1 is a longitudinal section of a spiritlamp forincandescent light. Fig. 2 is across section on the line 00 0c of Fig. 1. Fig. 3 shows the same cross-section as Fig. 2, except that a duplex gasifier is used. Fig. 4 shows a modified construction of the superheater entering the mixing-chamber.
In order to produce a greater effect of heat in the burners, the present invention provides a superheating-body 1), running from the burner A and guided down into the mixing-ohamber B.
In the apparatus shown in Fig. 1 the superheater 1) serves to support the carrier (1 of the incandescent body 0; but the incandescent body can be supported in any other convenient manner.
The superheater b penetrates into the mixing-chamber and serves to produce a greater effect upon the burner A and also a greater illuminating power in the incandescent body 0 as the mixture of air and gas that circulates in the mixing-chamber B comes in contact with the superheating-body b and becomes heated in said mixing-chamber, and reaches the point where it comes to combustion only when at a very high degree of temperature. A gasifying device D is attached to the mixing-chamber, and this consists either of a single Wicloholder e, as shown in Fig. 2, or a double or multiple wick-holder, as shown in Fig. 3. This Wick or holder is heated in the ordinarymanner by a light heating-flame f in order to generate gas. A protecting casing is shown at g for the flame. I11 order to facilitate the discharge of the gas generated by the heat inside the wick holder or holders into the mixing-chamber, one or more chambers or tubes it pass longitudinally through the wick E, which are pro vided in their length with perforations or openings 2', which enable the gas generated by the heating-flame f in the wick E to pass into the outlet-channel it. As the outletchannels of tubes h are higher than the wick and the latter leaves a free space in the up per part of the wick-holder c, it is evident that the gas generated in the gasifier can easily flow to the gas-discharge 0 through the outlet device K.
The heating-flame f is fed by a separate wick f, which can be raised or lowered bya wheel or other suitable device, according to circumstances. The use of a duplex gasifier, Fig. 3, enables me to have a better efiect of the heating-flame f and to use Wick-holders e of a smaller cross-section. The discharge a, as can be seen in Fig. 1, consists of an open socket, the upper edge of which is provided with indents forming outlets about the valveshaped conical extremity Z) of the superheater 1).
The inlet of air in the mixing-chamber B is by openings m, the cross-sections of which can be changed by means of a ring 01, provided with openings and turned by means of a lever 0. 19 is a valve-spindle which serves for preventing the outlet of the gas coming out of the gasifier D in order that the main heating-flame shall not continue to burn. after the secondary heating-flame has been extinguished.
The superheater b, which reaches into the mixing-chamber B, is of great importance for spirit-lamps for incandescent lights, because when the spirit is gasified the water contained therein is also carried along, and this Will greatly impair the working of the burner if it Were not made harmless by the high superheating produced by the superheater b reaching into the mixing-chamber B before the combustion of the gas and air mixture. 'Asieve q is also introduced in the mixing-chamber B, which not only prevents the main heatingflame from blowing downward, but causes also a further intimate assimilation of the masses of gas and air entering the mixingchamber B, and, moreover, by its position an especially high overheating of the ready mixture of gas and air through the upper extremity of the superheater.
As the superheater b is heated by the main heating-flame at its upper end, at the hottest places, and as it is made of metal or of some other material a good conductor of heat, it will be easy to understand that the heat communicated to the upper end will be transmitted to the lower end of the superheater b, and that thereby, according to the shape of the superheater, a suitable heating-surface will be acquired for the superheating of the gas and air mixture in the mixing-chamber, and the superheating will occur according to the counter-current principleI mean, the gas flowing out of. the openings 0 and the air coming into said openings get hotter and hotter as they How to thehead of the superheater and come to the point of combustion, being at a very high degree of temperature, so that by means of this apparatus the highest light effect is produced Without using more gas. The superheater b, which enters the mixingchamber 13, can also be placed opposite or above the gas-opening c, as seen in Fig. i.
If it is desired to use the superheater with a burner for incandescent light fed by gas from a main, the gasifying device is of course removed, as it is necessary only where the gas is to be generated. It is evident that the shape of the superheater, as well as the regulating of the inlet of gas and air and the proportion of the gasifying when volatile liquids are used, can be varied without interfering with the principle of the invention, which consists in the use of a superheater reaching into the mixing-chamberin order to obtain a high superheating of the gas and air mixture passing through the mixing-chamber according to the counter-current principle.
I claim- 1. A burner for incandescent gas-lamps comprising a mixing-chamber, a gas-conduit opening into the same, air-inlets at the bottom of the mixing-chamber and a superheating-rod extending down from the main gasburner to a point directly above the gas-inlet and adapted to deflect the inflowing stream of gas laterally to mix with the air rising in the mixing-chamber.
2. In combination, the mixing-chamber, the gas or air inlets, a superheating-rod extending down from the main burner to a point directly above the gas-inlet, a reservoir, a generating-chamber D, a wick E extending from the reservoir to the chamber D, a conduit from the chamber D to the mixingchamber and a generating-burner alongside the wick E, substantially as described.
In witness whereof I have hereunto set my hand in presence of two witnesses.
