ED STATES WILLY GGSMANN, O'F HANNOVER, GERMANY.
BURNER.
Application filed August 17, 1921.
Serial No. 493,073.
(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L., 1313.)
To all whom it may concern:
Beis known that I, VVILLY GosMANN, a citizen of Germany, residing at Hannover, Germany, have invented certain new and useful Improvements in Burners (for which I have filed an application in Germany August 3, 1920), of which the following is a specification.
My invention relates to burners and more especially to a device for insertion into the mixing tube of a Bunsen gas burner and its object is to reduce the consumption of gas, particularly of gas for heating purposes by effecting a more complete combustion of the gas.
According to the present invention this reduction of the gas consumption is attained by thoroughly mixing the gas with the air of combustion by means of a nozzle-like deyice inserted in the mixing tube or cham- It has already been proposed to insert into the mixing tube of gas burners twisted flat springs, which could be expanded, wire-gauze sieves and spirals of wire, which taper towards the burner and which were put directly on the nozzle for the gas, where they act as non-return valves. These devices, however, only served the purpose of preventing back-firing.
The device according to my invention con sists of a wire coil, the windings of which are gradually reduced in diameter and form a truncated cone. The windings may be 5 located so close together that they form a closed mantle with spirally corrugated surface. If the spirals are wound with a clearance between them, the gas and air mixture can escape between them to the outside of the coil, whereby throttling of the mixture is efiectively avoided. Furthermore the flexibility of the coil is increased and the introduction of the device into the mixing tube through the air inlet is greatly facili- 5 tated. Some gas stoves do not possess an air inlet suitable for the introduction of this supplementary nozzle and in this case it is necessaryto introduce it from the burner end, which is only possible with a spiral having spaced windings.
In a preferred form the wire at the rear end of the spiral is drawn straight out and protrudes from the mixing tube, where it is formed into a handle, which facilitates the removal of the device. The handle further enables the coil to be properly adjusted within the mixing tube. It is advantageous to push it nearer the burner in case of high gas pressure and to pull it towards the gas nozzle in case of low gas pressure and thus in the latter case to increase the effect of the nozzle in sucking air into the mixing tube.
In a coil with close windings a disc of wire gauze such as commonly employed for the prevention of back-firing, may easily be fixed between the windings and as the device may easily be withdrawn by means of the handle the cleaning of the coil and the sieve is greatly facilitated.
In the drawings affixed to this specification and forming part thereto a burner embodying my invention is shown by way of example.
Referring to the drawing, a is the mixing tube or chamber, 6 the burner and 0 the gas nozzle. In the forward portion of the mixing tube or chamber a is disposed the conical wire coil or spiral OZ, which terminates in a straight extension e, projecting from the tube a through the air inlet 7 and shaped into a handle g. Clamped between two turns of the spiral d is a wire-gauze sieve h.
'When the mixture of gas and air passes through the nozzle-like spiral or conical coil d, the currents are set into circular n10- tion, whirled and thoroughly mixed together.
In the example illustrated a round wire is shown, but the wire may have any other cross-section, for instance rectangular, so that the current of gas and air impinges upon plane, spirally wound guide surfaces.
I wish it to be understood that I do not desire to be limited to the exact details of 95 construction shown and described, for obvious modifications will occur to a person skilled in the art.
I claim:
1. In a device of the kind descri bed in combination, a burner tube, a closely Wound handle extending in parallel to the axis from wire spiral forming a truncated cone and the base thereof, and a sieve inserted bea handle extending in parallel to the axis tween two windings of said spiral. 1
from the base thereof. In testimony whereof I afiix my signa- 2. In a device of the kind described in ture.
combination, a burner tube, a closely wound Wire spiral forming a truncated bone, a I WILLY GOSMANN.
