Description
Sept. M, W35, 0. J. LEINS IGNITER FOR GAS BURNERS Filed July 28, 1930,
Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE 8 Claims. (01. 158115) The instant invention is in the nature of'an improvement on the lighting device illustrated 15" and described in United States Letters Patent No.
1,747,015, issued February 11, 1930.
The instant invention provides means for automatically reigniting the, gas issuing from the burner in cases where the flame is extinguished 20 as above pointed out.
My invention is illustrated in the accompanying drawing in which:-
Figure 1 is a plan view of an arrangement embodying my invention, and
25'. Figure 2 is a partial sectional view taken on the line 22 of Figure 1, looking in the direction indicated by the arrows.
The usual gas manifold is illustrated at 3. The gas burner is illustrated at 4, this burner being fed from the manifold 3 by the usual feed pipe 5, to which air is admitted, in the usual way, at the end nearest the manifold. Gaseous fuel is lead into the feed pipe 5 by way of the nozzle pipe 6, from manifold 3, in which nozzle pipe the usual gas cook I is provided.
An igniter is provided in appropriate proximity to the burner 4. This igniter comprises a tube 8 leading from the manifold 3 and terminating in a torch head 9 an appropriate distance from the 40 burner 4. Although only one burner is shown, it is, of course, understood that gas ranges embody a number of burners, usually four, and the torch ,head 9 is disposed centrally within these circularly arranged burners. A protecting hood I is 45 mounted over the torch head 9 upon a flanged perforated collar I2 supported on the upcurved end of the tube 8, as shown in Figure 2, below the torch head. The hood II] has the flue II, opening at. the top, and four openings I3, I3 in the V V 50 circular side wall, each in line with the respective burner on the range. A tube I I leads from each opening I3 toward the respective burner, as illustrated, each of these tubes having the longitudinally slot I4 at the bottom thereof to 55 provide for the entry of air. As illustrated, each of the tubes I I, M extends a short distance into the hood I0 and its inner end at the top is provided with an ear I l in clamping engagement with the flue member I I, the upper end of which,
in turn, is in clamping engagement with the top 5 of the hood.
The torch head 9 has a pilot flame opening I6 and is fed by Way of the tube 8 from the manifold 3, a coupling I5 being provided. This type of coupling is shown in Patent 1,747,015 and detailed 10 description here is unnecessary. Sufiice it to say, for present purposes, that this coupling has a constant by-pass, adjustable by the valve screw I5, by which arrangement a constant pilot light is maintained at the opening I6.
Extending from the burner 4 toward the re spective adjacent tube It is a small tube It which carries at its end the torch head ll extending upwardly into the respective tube I4, as illustrated. This torch head has the port I8 drilled in the side thereof and so positioned as to be directed toward the burner l, and the port I9 drilled in the opposite side thereof and so positioned as to be directed toward the pilot flame at I6.
When a burner d is to be ignited, the cock 1 associated with that burner is open and gas enters the burner ready to be ignited at the burner openings 4', 4'. Gas also passes through the tube IE to the torch head i! issuing therefrom in both directions, one stream of gas from the port I8 301 toward and over the burner 3 and the other stream of gasthrough the port 99 toward and to the pilot flame at I 6. The gas issuing from the port I9 in the torch head I? into the tube flows toward the torch head 9 and is ignited by the pilot flame. The flame is then conveyed back to the torch head I! and to the stream of gasv issuing from the port i8, thus causing a flame to be projected over the burner 4 to ignite the gas issuing from burner openings l. The gas issuing from the torch head I 7 remains ignited so long as the gas cock I is open and the continuing flame at I8 is essential to the instant invention as will now be pointed out.
It will be clear that the initial projection of the flame at I8 is due to the initial rush of gas into the burner 4, and before the pressure thereof is relieved by the issue of gas through the burner openings 4'. By the time the pressure is thus relieved, however, the gas issuing from the burner openings 4', or enough of them to light the others, is ignited and the flame at I8 then subsides to appropriate pilot proportions.
'In the event that liquid, boiling over the sides of a vessel disposed over the burner, falls upon the burner, and quenches the flame thereon, it does so just to the extent that the liquid fills the burner openings 4'. 'Just to the extent that burner openings 4 are closed the pressure within the burner is increased. This increase in pressure causes the projection of the flame from the port l8, over the burner, as indicated in Figure 2, and as soon as the filled burner openings become cleared by the evaporation of the liquid therein, the gas issuing therefrom is ignited by this temporarily projected flame. As such reignition takes, place, the gas pressure within the burner is obviously gradually restored and, accordingly, the
.flame at [8 gradually recedes to resume appropriate pilot proportions. Obviously, except for this automatic reignition, the gas which would issue from the cleared burner openings 4 would be unignited, entailing the danger hereinabove referred to. It will be noted that torch head I! is protected by tube I4 against quenching.
