GAS HEATING BURNER Filadhug. 12.1927
Patented June 24, 1930 UNITED STATES PATENT? OFFICE ANNIE ALICE'SCOTT, EARNEST HERBERT SCOTT, AND PERCY RANDALL SCOTT, OI
. CHRISTCHURCH, NEW ZEALAND GAS-HEATING BURNER Application filed August 12, 1927, Serial No. 212,594, and in New Zealand February 11, 1927.
This invention relates to a burner for use in gas cooking appliances and refers more particularly to a burner of this nature designed to provide a choice of three intensities, namelyfa small flame suitable for slmmering and the like, a relatively larger flame adapted for boiling and general cooking, and
a combination of both of the said flames for use in cases where a more intense heat is required.
A burner of this nature hitherto constructed has consisted of a pair of fuel pipes or passages horizontally disposed in parallel relation one above the other and each adapted at; one end to connect with a suitable controlling cock by means of which gas is supplied, such pipes or passages being both provided near their said gas-receiving ends with air-admission openings by means of which the necessary proportion of atmospheric air is admitted to form the desired combustible mixture.
At their other or opposite ends the said pipes or passages terminate at their respective levels in a vertically disposed chamber closed at its lower end and having its upper end open.
The said vertical chamber is formed at a level between the entrances of the two fuel pipes or passages with a flange designed to receive the lower end of a tubular member arranged within such member to extend coaxially therewith and thus divide the said chamber in two concentric portions namely, an inner portion consisting of the bore or interior of the said tubular member such inner portion being in communication with the lower fuel pipe-or passage and an outer the open upper end of the chamber. 1
The upper end of the said tubular member is enclosed by means of a plate or inverted cone arranged to overlie the said flange while to permit the escape of fuel from the said inner and outer portions of the chamber respectively, such escaping fuel being adapted to be ignited'so as to issue from the notches in the form of jets of flame.
In the said previous constructions, however the upper fuel pipe, which communicated with the outer portions of the chamber has been designed to provide the larger or boiling flame, while the lower fuel pipe, com municating with the inner portion of the chamber has provided the smaller or simmering flame.
With this arrangement the notches in the lower side of the flange have been made large to permit the issue of the larger or boiling flame while those in the upper side of such flange have been relatively smaller to permit the issue of the smaller or simmering flame.
With this arrangement however, it has been found that when both flames are employed together, the larger jets being arranged below, are apt to rob the smaller jets of the necessary supply of free air to support proper combustion, and in consequence the said smaller jets have contributed little to the heating effect. The said arrangement is open also to the further objection that the larger flame is apt to blow back and so ignite the fuel in the portion of the fuel pipe in which the aforementioned air-inlet occurs.
It is the object of the present invention therefore to provide a' burner of the type described in which the above mentioned objections will be minimized or overcome.
In carrying this object into effect according to the present invention the upper fuel pipe communicating with the outer portion of the chamber is employed for the simmering flame which by this arrangement issues .at the underside of the flange of the tubular member through small radial notches or openings formed in the underside of the said flange, or, if thought desirable in the upper edge of the chamber.
In this construction the lower fuel passage communicating with the inner portion of the chamber is employed for the larger or boil ing flame which issues at the upper side of the said flange through relatively larger notches or openings formed in the upper slde mentioned.
Referring now to the accompanying drawings which illustrate a constructional embodiment of the invention, Figure 1 is a part sectional elevation showing the general construction of the preferred form of the invention,
Figure 2 is a plan view corresponding to Fig-' ure 1, but with the cone shaped cap and spindle and the tubular sleeves removed. Figure 3 is an elevation of the tubular sleeve showing the radial lugs on the upper face and the V shaped notches on the under face of the flanged end, Figure 4 is a plan view corresponding to Figure 3, Figure 5 is a sectional elevation on lines 55 on Figure 2, and Figure 6 is a sectional elevation on lines 66 on Figure 2.
According to this invention a pair of fuel pipes 1 and 2 are provided, the pipe 2 being horizontally disposed in parallel relation above the lower diametered pipe 1, the end 3 of the pipe 1 having a hole 3 and the end 4 of the pipe 2 being open, both ends beingadapted thereby to be connected with suitable controlling cocks regulating the inflow of gas; air admission openings 5 and 6 respectively provided near the ends 3 and 4.
The opposite end of the pipe l is integral with and terminates in a vertically disposed cylindrical chamber 7 provided with an annular seating 9. A boss or lug 10 is provided cast integral with the cylindrical chamber 7, and the end 11 of pipe 2 is adapted to be cast in the lug 10 withi'side walls 12- to secure the pipe 2 preferably cut from a piece of metal tubing along the length of the pipe 1.
An inner vertically disposed cylinder 13 open at bothends is flanged outwardly at its upper end 14 the under side 15 being adapted to seat on the face 16 of the chamber 7 and the lower end 17 to seat on the face 9 also of chamber 7 Radial lugs 18 are cast integral with and on top of flanged end 14 and V grooves or notches 19 are cast or cut in the underside of the flanged end 14. Each notch 19, is arranged to be centrally situated below each lug 18. The openings; formed by the closely upon the upper faces of the lugs 18.
A spindle 23 screwed into the disc 21 (or inphere, While the fuel from pipe 2 passes up between walls of chambers 13 and 7 and passes out to the atmosphere through V notches 19.
Any known and suitable regulating means may be provided to control the supply of air to the larger fuel pipe 1.
We claim. I
A gas burner comprising a lower fuel pipe of comparatively large diameter having gas and air inlet openings, an upper fuel pipe of less diameter, also having gas and air inlet openings, a structure forming a chamber into which said upper pipe discharges, a cylinder in said chamber into which said lower pipe directly discharges, said cylinder having its wall flared outwardly at the upper end and provided on the upper side of said flared ortion with comparatively large openings or discharging mixed gas and air from the lower pipe for a flame of greater intensity, and comparatively small openings on the lower side of said flared portion for discharging mixed gas and *air from the upper pipe for a flame of lesser intensity,
and a deflecting cone covering the upper end of said cylinder.
In testimony whereof we afiix our signatures.
