UNITED STATES PATENT OFFICE some John H. Sattler, Downey, cam. Application March 5, 1935, Serial No. 9,393
: 6 claims. (01. 158- 116) This invention is a gas burner for a cooking top or the like and has for an object to prevent the flameblowing oil the burner ports.
It has a further object of the invention to em-,
- ciently mix the air and gas of the combustible mixture and uniformly distribute it to the burner ports so as to insure an even flame of high temperature.
More particularly it is an object of the in- 10 vention to adapt the burner for discharge of gas into its mixing chamber at high velocity whereby a relatively large volume of air may be drawn into the mixing chamber for so proportioning the air and gas asto insure complete combustion and high flame temperature, with the resulting high velocity of the combustible mixture'appreciably reduced before ignition so as to prevent the flame blowing oil the burner ports.
It is another object of the invention to baiile m the combustible mixture before discharge at the burner ports so as to uniformly mix the air and gas and evenly distribute the combustible The burner comprises a body I communicating d thafuelpipe2whichterminatesinausual mixing chamber 3. A valve 4 regulates adm'is sion of air to the mixing chamber, and'a Iuel- 4 nozzle (not shown) extends into the mixing chamber through an aperture 5 and supplies iuel such as natural gas, which due to its velocity draws air into the mixing chamber to form a combustible mixture. g
5 To provide an air-gas ratio which will insure complete combustion and high flame temperature, the velocity of the gas at its supply nonle should be relatively high and the valve l should be adjusted to admit a comparatively large vol- 50 ume 01 air, but the resulting high velocity oi the combustible mixture may produce an incomplete mixture 0! the air and gas, and may unevenly distribute the combustible mixture, and may blow the name from the burner ports. u The present invention provides for admission 0 axis of the annular burner.
I gas and air so asto insure an'eiiicient combustible mixture, but baiiles and retards the high velocity of the iuel mixture so as to prevent the flame blowing qifl the burner ports and at the same time insure even distribution and high flame '5 temperature.
As an instance of this arrangement burner ports open into a chamber which receives ,the. combustible mixture from pipe 2, the body I preferably forming an annular bowl ll communicatl0 ing with the fuel pipe 2, with the inner and outer peripheral rims ll-i2 of the bowl cooperating to define a seat for a cap .l3 which provides a closure for the bowl and in which the burner ports are formed. '5 For efllcient distribution of the flame the burn-1 er ports preferably, define an o'uter annular row comprising a large number of ports discharging angularly outwardly and upwardly. and an inner annular row consisting oi relatively few ports discharging angularly upwardly and toward the As an instance otthis arrangement the seat "-42 ,may be an inverted truncated conical seat and the cap I! -may be a cooperating inverted truncated cone. as
Alternate slots and ribs ll-ii of some appreciable length are formed in the peripheral sur-' face of cone i3 adjacent its base, with the slots terminating at an annular rim whiclris at the base of the cone as shown at II; and apertures ll are formed in the cap l3 medially of the length of its axis and are inclined upwardly and inwardly toward said axis.
The seating surfaces between the body i and the cap it are preferably machined,- whereby the cap fits tighthv against seat It and the ribs iI'iit tightly. against seat ii, the parts being preferably held in assembled relation by a clamping screw [8 extending through transverse spider II at the lower-end of truncated cone "and engaging a 40 spider 2| which extends across the annular body I adjacent its base. The bowl II is thus tightly closed except for the slots it and the apertures ports discharging upwardly andoutwardly between the upper edge otthe'seat i: and the annular rim It. The apertures i'l'provide inner burner ports, and are appreciably circumferentially spaced from one anothersoasto forma relatively small number of ports discharging upwardlyandinwardlytowardtheaxisotflie burner. The ports ll-l'l thus cooperate for sired distribution or the total flame.
The outer ports being closely adjacent one another and extending the length of the slots ll,
the velocity of the combustible mixture will be appreciably reduced at these ports so as to avoid the flame being blown off; but the inner ports being appreciably spaced Irom one another and thus liable to have the flame blown 03, means are preferably provided for reducing the velocity at these ports. For this purpose 9. lug 2! may project from the surface of cap 13 and into the bowl Ill at each of the apertures I1, and the apertures open'through the lugs into the bowl II with their upward and inward angularity uniformly prolonged, thereby forming discharge ports of appreciable length so as to reduce the velocity ofthe combustible mixture discharged through these elongated ports.
The construction as thus described also provides means for baflling the combustible mixture in bowl It, in that the circumterentinlly timed ty of the fuel is somewhat retarded. by the battles before it enters the discharge ports, and the baifles evenly distribute the fuel to the discharge The invention thus reduces the velocity of the fuel at, the burner ports, permitting the combustible mixture to be drawn into the fuel pipe 2 at highvelocity so as to insure an efllcient combustible mixture without danger of the" flame being blown from the burner ports; and the invention also baiiies the flow of the combustible mixture so as-to insure .uniform distribution and eflicient combustion.
The burner is thus quiet in operation and produces an intense flame, due to. proper proportioning oi. air and gas, even distribution oi! the combustible mixturejand prevention of flame blow ofi. a l
