Dea.4 31, 1935. s. MORGAN GAS BURNER Fi1ed May 29, 1954l .4, of the Patented Dec, 3l, 1935 GAS BURNER Swney Morgan, OFallon, Ill. Application May 29, 1934, serial Nc. 728,090
5 claims. (01.158-116) 'Ihis invention relates to gas burners and more particularly to such burners as are employed with cooking stoves, hot air furnaces and steam and hot water boilers.
The general object of the invention is .to provide a burner, the parts of which can be rapidly and accurately machined and easily assembled or disassembled.
Another object is to produce a burner in which the gas and air is subjected to mixing and expansion before reaching the discharge passage.
Another object of the invention is to provide a burner that will operate on any of the gases now commercially used without any change in the burner itself.
The foregoing and other objects and advantages will be understood from the following description considered in connection with the accompanying drawing, in which:
Figure 1 is' a longitudinal sectional view of my improved burner;
Figure `2 is a plan view of the burner; and
Figure 3 is a side elevation of the burner headA detached.
Referring more particularly to the drawing B denotes the burner as a whole, comprising a mixing tube I, terminating at its inner-end in a bowl shaped portion or outer member 2, in which a burner head or inner member is removably mounted. The burner head consists of a hollow cylindricalportion 3 having .an upwardly and outwardly ared annular flange 4 at its upper end. 'I'he mixing tube I and the lower end of cylindrical portion 3 of the burner head are threadedly connected as at 5.
The top edge or rim of the bowl 2 is formed with a downwardly and inwardly inclined extension 8 and depending from this extension is a hollow cylindrical skirt portion 9. This skirt portion extends parallel with and in spaced re'- lation to the hollow cylindrical portion 3 of the burner head, while the opposing faces of extension 8 and annular ange 4 are also parallel with and spaced from each other. These opposing faces are preferably highly machined to present smooth surfaces to the air and gas mixture flowing through the annular orice or slot I0, formedthere-between. A plurality of projections II, preferably not more than three in number, formed on the under face of the flange burner head limit the extent to which the burner head can bescrewed h'ome in the mixing bowl or chamber, and 'thus determine the width of theslot or port. Il).l The hollow cylindrical portion 3 ofthe burner head lis pro` Isure over the measuring ports.
vided with a ring shaped raised portion in ,which vertical slots I2 are cut, thus forming spaced radially extending projections I3, intermediate its lower end and the flange 4. The projections I3 engage the skirt 9, serve as a guide and sup- 5 port to the burner head and together with the. wall of the skirt seal the sides of the vertical slots I2.V
When the burner head is screwed home the thus formed open ended slots I2 become the pri- 10 mary or measuring ports for the gas flowing through the burner, and at the same time the projections I3 hold the burner head in its central position. It will of course be understood that the radial projections I3 are of a length 15 or depth to just t within thecircular opening or passage I Il through the bowl. v The annular orifice or ring shaped slot I0, which constitutes a circular continuous single secondary port communicating at its inner annular end with a ring-shaped chamber I1, im-
mediately above the vertical slots I2, supports an Y annular vfiame when gas is supplied to the burner. Gas is supplied to the mixing tube from a gas cock I5, which discharges the gas ina con- 25 -shaped mixing chamber I6, in the bowl 2, in-
spiratingair enroute. The mixture then ows 35 in predetermined quantities through the vertical primary ports or slots I2, which are of the area required to give the-*proper flow of gas.
After leaving the primary measuring ports I2,
the mixture enters the ring-shaped chamber I1, 40 the area or capacity of which is muchlarger than the area or capacity of the primary or vmeasuring ports I2. This large area allows the gas mixture to expand and to equalize the pres- 45 As is customary with burners of this type a number of small inwardlyinclined ports I8, extending through the flange 4 of the burner head, and communicating with the single circular port III, are provided. These ports I8, direct the mix- 50 ture toward the center of a cooking vessel, not` shown, and preclude the possibility of a central relatively cold spot.
The mixture Hows from the ring-shaped chamber I1 into the single circular secondary port or 65 slot I0, and thence through this slot and through the individual inwardly inclined ports I8 to the air, where it is burned. Since the mixture must pass through the primary or measuring ports I2, which are xed in size, on its way to the secondary ports IIJ and I8, it follows that the burner head could be moved upwardly, that is partly unscrewed without materially aiecting the amount of gas flowing through the secondary ports. Therefore, it is possible to adjust the width of the slot I0, permanently by means of the projections II, so that the burner would burn many ofthe gases now in commercial use by merely changing the size of the orifice in the outlet of the gas cock I5, and readjusting the air shutter 1.
While I have described and shown but one embodiment of my invention, I do not Wish to limit myself to the exact description, as it is evident that modifications are possible without deparing from the spirit of the invenion.
Having thus described my invention:
What I claim is:
1. In a burner for gaseous fuels, a burner head comprising a ring shaped mixing chamber, a. second smaller, ring-shaped mixing chamber above said first chamber, vertical passages of predetermined cross section connecting said rst mixing chamber with said second chamber and a circumferential outlet slot of predetermined width circumferentially connecting said second chamber with the open atmosphere.
2. Ina. burner yfor gaseous fuels, a burner head comprising a ring shaped mixing chamber, a second, smaller, ring shaped mixing chamber arranged above said ilrst mixing chamber in axial alignment therewith, vertical passages of predetermined cross section connecting said first mixing chamber with said second mixing chamber and a circumferential outlet slot of predetermined width circumferentially connecting said second mixing chamber with the open atmosphere.
3. In a burner for gaseous fuels, a burner head comprising a ring shaped mixing chamber, a second, smaller, ring shaped mixing chamber arranged above said first mixing chamber, a -plurality of vertical passages of predetermined cross section connecting said rst mixing chamber with said second mixing chamber, a circumferential outlet slot circumferentially connecting said second mixing chamber with the open atmosphere and means for limiting the width of said slot, the combined cross sections of the said vertical passages being smaller than the cross section of said second mixing chamber. 10
4. A burner for gaseous fuels comprising a primary mixing chamber, a secondary mixing chamber connected with said first chamber, a ring shaped mixing chamber of less cross section than said secondary mixing chamber arranged above said last chamber in axial alignment therewith, a plurality of symmetrically arranged vertical passages of predetermined cross' section connecting said secondary mixing chamber with said ring-shaped mixing chamber, and 2o a circumferential outlet slot of predetermined width circumferentially connecting said ringshaped mixing chamber with the open atmosphere.
5. In a burner for gaseous fuels, a burner head comprising Aa bowl-shaped portion having 4an integral skirt portion arranged in substantially parallel relation with respect to the inner wall. thereof to form a ring shaped chamber open at its lower endL a hollow cylindrical vmember including a cone shaped top portion threadedly connected with Asaid bowl. shaped portion in spaced relation with respect to said skirt portion, and relativelyshort guiding projections on said cylindrical portion contacting with said skirt adjacent to the bottom portion thereof and forming a plurality of vertical passages of limited cross sectional area, the top portion of said bowl shaped portion being cone-shaped and the top portion of said cylindrical member being arranged parallel to the top portion of said bowlshaped portion in slightly spaced relation for forming a circumferential outlet passage at the upper end of said burner head.
