Description
J. C. S. KOCH GAS BURNER FOR HEATING AND COOKING PURPOSES Enema-b, v, 1925 Patented July 14, 1925.
UNITED STATES JULIUS CARL SIEGFRIED KOCH, OF HAMBURG, GERMANY.
GAS BURNER FOR HEATING AND COOKING PURPOSES.
Application filed. February 7, 1925. Serial No. 7,567.
T 0 all whom it may concern:
-Be it known that I, JULIUS CARL SIEG- FRIED Koorr, a citizen of Hamburg, Germany, residing at Hamburg, Germany, have invented certain new and useful Improvements in a Gas Burner for Heating and Cooking Purposes, of which the following is a specification.
The present invention refers to a gasburner for heating and cooking purposes which, as has been proved by scientific investigations, is distinguished from burners known heretofore by its extraordinary efli ciency. By a model it has been proved that the highest degree of etficiency is 72.18%. In the new burner the mixture produced in a known manner by a vertical mixing nozzle is led close up to the table of the burner whereupon it is expanded by radial exit openings to a disk-like plane by additional air being added. The novelty resides in that the mixture of gas before being expelled from the rad'al apertures passesacross the mouth of an annular space intermediate the -feed pipe and the mantle of the burner head, the additional air being fed to the annular space at a given distance below the outlet apertures. The mantle surrounding the feed pipe for a certain distance is provided on its outer surface with broad outlet slits. The flame thus produced will have a diameter of from 20 em. up, so that a single burner will be sufiicient to heat even large pots and other vessels, as for instance copper boilers.
An embodiment of the invention is shown with accompanying drawings wherein:
Fig. 1 shows a burner constructed according to the present invention, in elevation, the protecting hood being shown in section.
Fig. 2 is a vertical section, and
Fig. 3 is a horizontal section on the line 33 of Fig. 2. 4
The gas is fed in by the pipe 1 and enters the burner by the first nozzle 2 mixing with the air entering the burner by the openings 3 which preferably rise at an angle inwardly and upwardly. The gas mixture thus produced passes through a second nozzle 4 and, is again mixed with air entering by openings 5. The thus dilated gas mixture is fed into a central tube 6 of comparatively large diameter opening out close to the inner face of a table 7 of the burner head. This table is mounted on a mantle 9 having broad outlet slits 8. Intermediate the mantle 9 and the tube 6 is an annular space, the mantle being held in proper position by strips 10. An additional amount or" air is allowed to pass into the space between the tube 6 and the mantle 9 by apertures 11. This air flowing upwardly in the annular space will be preheated by the mantle 9 of the burner head which is itself very hot.
Themixture produced by the nozzles 2 and 4 will spread disk-like to the sides on striking the table 7 and over the rim of the tube 6, and before leaving the burner by the broad slits 8 will be given an additional amount of preheated air moving at right angles to the plane of the table 7 which air on account of meeting the gas mixture at right angles will intimately mix with this gas mixture. The flame produced by the burner is subjected to a very high pressure, and therefore will spread out to a great degree.
It may be advisable to construct the mantle to have the openings or slits 8 slidably adiustable in a vertical direction, so as to allow the flame to approach the cooking pot more or less in a manner known per se. Such adjustability will be advisable for regulating the heat and for avoiding burning the food. a
The raising and lowering of the mantle can be carried out by the aid of an implement of any desired construction, such for instance as a wedge to be inserted at the meeting line 13 between the mantle 9 and the lower part 12 of the burner. In the construction shown the raising and lowering of the mantle 9 can be carried out by a double-armed lever 15 pivoted at 14 to the lower part 12 of the burner. This lever is articulated to a rod 16 and is adapted to engage a pin 18' on the mantle 9 by a slot 17 arranged on the free end of the upper arm'of the said lever. By reciprocating the rod 16 the mantle 9 can be raised and lowered at will. When the mantle is thus raised the slits 'or openings 11 are enlarged.
On the outside of mantle 9 a conical protection hood or guard 17 is mounted outside,
which prevents contact of the flame at the I slits 8 with the air entering the openings 11 and with the air entering the openings 5 or 3 with resulting production of flames and pushing back of the incoming gases.
I claim:
1. A gas burner for heating purposes,
comprising, a mantle, a horizontal spreading table supported by the mantle, radial gas outlets in the mantle and immediately below the table, a tube positioned within and spaced from the mantle to leave, an annular space therebetween, air inlets in the mantle, the upper end of the tube being open and terminating adjacent the table, a mixing nozzle positioned to feed into the lower end of the tube whereby the mixture from the mixing nozzle is forced to spread out upon meeting the table and to pass across the-mouth of the annular space be- 1fore passing out through the radial gas outets.
2. A gas burner according to claim 1. said air inlets in the mantle being positioned adjacent the plane of the base of said tube.
99 3. A gas burner according to claim 1,
aaaaee radial gas outlets in the mantle and imme-' diately below the table, a tube positioned wholly within and spaced from the mantle -to leave an annular chamber therebetween,
air inlets in the mantle communicating with the annular chamber, the upper end of the tube being open and terminating immediately adjacent the table, and a mixing noz zle positioned Within the mantle to feed into the lower end of the tube.
5. A gas burner according to claim 4, said air inlets in the mantle being positioned adjacent the plane of the base of said tube.
