UNITED STATES PATENT] OFFICE GAS BURNER August Berning, Essen, Germany, assignor to Robert Muller, Essen, Germany Application January 22, 1936; Serial No. 60,258 In Germany August 20, 1934 6 Claims. (Cl. 158-118) The production and supply of the required On the accompanying drawing an example of compressed or blowing air by means of mechania burner according to the invention is illustrated, cal devices for compressed air-gas burners which Figure 1 shows a longitudinal section, taken areknown up to the present time, such as comon line I I, Fig. 2,

pressors, and fans and such like is disadvanta- Figure 2 shows a cross section through the 5 geous in that the compressors, and fans requireburner taken on line II--II, Fig. 1.

A further disadfield e when the alternating circuit is shut, and. vantage of these devices is to be found in the which magnetism causes the diaphragm ,f to insuflicient mixing of gas and air, whereby the swing in a number of vibrations resulting irom difierent air and gas streamlines flow one beside the frequency of the alternating current. Herethe other without mixing intensively. by, an air movement is caused in the diaphragm l5 By this invention, the arrangement of all rochamber 9 in such a way that the fresh air is tating and sliding parts are made superfluous sucked into-the diaphragm chamber 9 through owing to the fact that the required air is adopening (1 made in the air pipe 2', and opening h mitted into the gas stream by a known electromade in the surrounding tube t, and is blown in magnetic diaphragm blowing apparatus. The puffs into the upper mixing chamber is through 20 air is, thereby fed to the gas stream, contradisthe air pipe i.

In this way, the quantities of the and the gaseous fuel may be intermittently fed. separate air particles may be adjusted so that The mixing of the gas with air or oxygen takes an air-gas mixture which is in accordance with place in a known manner in a mixing chamber the respective conditions will be produced. The

The mixing chamber that the air-gas mixture existing herein, when is built in such a way that it serves as buffer the apparatus is in operation, serves as shock for t a pulsations in Order to avoid fl absorber. It serves also for the purpose of de- 4,5 ing flame. creasing the energy of the separate air particles A further feature of this invention consists avoiding hereby a flickering.

Still another feature of this invention is adjustable and secures thebase in its position based on the fact that the quantity of the after the amplitude of the vibrations of the diarequired and thereby oi the constituents of the phragm hav bee regulated.

- gas-air mixture is brought about by the regula- I claim:

fuel-gas and air consisting of a diaphragm and an electro-magnet adapted to be excited by alternating current, said diaphragm being continuously vibrated by the electro-magnet for bringing one of the two constituents into the other, a mixing chamber, an inlet therein for supplying fuel-gas, another inlet for supplying air, a diaphragm chamber one wall of which consisting of said diaphragm, the diaphragm chamber opening into one of said inlets.

2. In an air-gas burner, a mixing chamber, a diaphragm chamber containing a diaphragm electromagnetically vibrated by alternating current, a pipe connected with the diaphragm chamber terminating in the lower end of the mixing chamber the upper end of which is open, an

, inlet opening into the said pipe, and another inlateral inlets opening into the said pipe for the air arranged between the mixing chamber and the diaphragm chamber, and another inlet for the fuel gas arranged in the lower end of the mixing chamber.

4. In an air-gas burner, means for mixing fuel gas and air consisting of an electromagnetic vibration'diaphragm apparatus containing a diaphragm, an electromagnet and means for varying the distance between the diaphragm and the electromagnet.

5. In an air-gas burner, a hollow socket, an electromagnet, a diaphragm chamber, both arranged in the interior of the socket, a burner pipe, a cap for closing the socket at the upper side and centrally bearing the burner pipe.

6. In an air-gas burner, a hollow socket, an electromagnet, arranged in the interior of it, a threaded cap for the upper side of the socket, a diaphragm vibrated by the said electromagnet and connected to the lower side of the cap, and a burner pipe centrally fixed to the upper side of the cap.
