11 Claims. (01.'158-115) This invention relates to lighting devices for gas burners, particularly to lighting devices of the type comprising a hood having openings in j line with the respective burners ,with a tube or 5,. conduit means leading from each opening toward the respective burner.

When a lighting device of this sort is applied to a gas range the tubes or conduit means leading from the hood frequently are positioned, in use,

lo' over the burner, or over a. torch head, or foot extension on the burner.

It is well known that in the use of gas ranges the burners should be adapted to be cleaned and removed.

l The present invention contemplates an improvement for permitting removal of the part of the conduit or tube means which is positioned in use over the burner or over the torch head, foot extension or other burner part from position 20 thereover to permit cleaning and removal of the burner.

The present invention may be used or modified for use with any existing type of lighting device such as the flash type of lighting device, or the gravity type of lighting device, and the present invention may be employed for removing the tube or conduit means extending to the burner from position over the burner or from position over a torch head, foot extension or other 30v means on the burner. So far as the present invention is concerned the lighting device may be adapted for use with gases having relatively high or any other B. t. u. Values, and the gas burners may be provided with non-quenching pilot means` 35 or they may be without such means as, for example, in the type of lighter illustraied and described in United States Letters Patent No. 1,747,015, issued February 11, 1930.

The invention is illustrated in the accompany- 40 ing drawings, in which: y

Figure 1 is a fragmentary plan view of an ar- .rangement embodying the present invention;

Figure 2 is a fragmentary partial section taken substantially on the line 2-2 of Figure 1;

Figure 3 is a view similar to Figure 2 showing the invention in connection with a gravity type of lighter; l

Figure 4 is a fragmentary plan view of another 50vembodiment ofthe invention; p A

" Figure 5 is a fragmentary partial section taken on the line 5-5 of Figure 4 with the burner and tubes in elevation; and

Figure 6 is an exploded perspective view show- 65 ing the hinge mounting for the tubes directed toward the respective burners in the device of Figure 5.

'Briefly stated, the present invention mounts the tube or conduit directed toward the burner so that it may be raised relative to the torch head 5 to permit cleaning and removal of the burner. Specifically this invention hingedly mounts this tube so that the part of the tube which overlies the burner may' be swung away from position thereover. The terms burner part and part 10 of the burner as used in the appended claims refer and are intended to cover the burner itself or anypart on the burner which .the tube directed toward the burner overlies and from position over which the tube is removed to permit cleaning and removal of the burner. This burner part or part of the burner may be the burner as above stated, or a part of the burner, or it may be a torch head, foot extension or other means on the burner and the term is used broadly in that sense.

In Figures 1 and 2 of the accompanying drawings the present invention is illustrated in connection .with the type of igniter arrangement i1- lustrated and described in the coperiding application of Oscar J. Leins, Serial No. 448,603iiled April 30, 1930. The usual gas manifold is illustrated at 5 and one of the gas burners is illustrated at B. The burner 6 is fed from the manifold 5 by feed pipe 'l to which air is admitted at 30 8 in the usual manner. Gaseous fuel is fed into the pipe 1 from the manifold 5 by the nozzle pipe 9 in .which the usual gas cock I0 is provided.

The ignitercomprises a tube Il leading from the manifold 5 andterminating in a torch head 35 I2 in appropriate proximity to the burner 6. One burner 6 is shown, but it is to be understood that gas ranges commonly embody a number of burners, usually four, and that the torch head I2 may be disposed centrally between such or any 40 other group of burners. A protecting hood I3 is mounted over the torch head I2 upon a flanged perforated collar I4 below the torch head I2, as

, 'shown in Figure 2. The hood I3 has a ilue I5.A

opening at thedtop, and four openings I6, I6 in 45 the circular side wall, each in line with the respective burner on the range. A tube I1 leads from each opening I6 toward the respective burner, and each of these tubes I1 is longitudinally slotted at the bottom thereof, as indicated at I8, to provide for the entry of air.

The torch head I2-has-pilot ilame openings I9 directed radially in line with the centers of the openings I6, respectively, there being four pilot ame openings I9 for a four burner arrangement 55 in the illustrated embodiment. At the end of the tube II near the manifold 5 a flash valve 20 is provided. This valve is of the type well known, which has a constant by-pass and which, when the button 2l is depressed, effects the ow of greatly increased quantity of gas. A pilot light is maintained at the ports I3 by the gas by-passed through the valve 20, and when the burner is to be ignited, its gas cock III is opened and the button 2I is depressed to admit the flow of the greatly increased quantity of gas to the lighter, this increased flow causing the pilot llames at the ports I9 to be projected radially outwardly, through the tubes I1, far enough to ignite the particular burner to which gas has been admitted.

Extending from the burner 6 toward the respective adjacent tube II is a, small tube 23 which carries at its outer end the torch head 24 extending upwardly into the respective tube I1, as illustrated.' rI'he torch head 24 has a port 25 drilled in the side thereof and directed toward the burner 6. When the pilot ilame from the ports 'I3 is projected by the depression of the button 2I, the gas issuing from the port 25 at` the opening of the gas cock I is ignited and remains ignited so long as the gas cock I0 is open. Near the top the flue I has openings 28 and the collar I4 has openings 29 and is clamped upon the upturned end of the tube II at 30.

In the event that liquid, boiling over the sides of a vessel disposed over the burner 6, falls upon the burner. it quenches the name therefrom by closing the burner openings 6', and this closing of the burner openings 6' increases the pressure within the burner. This increase in pressure causes the projection of the ame from the port 25, over the burner, as indicated in Figure 2, and as soon as the iilledpburner openings 6 become clearedby the evaporation of the liquid, the gas issuing therefrom is ignited by this temporarily projected ilame. As such reignition takes place, the gas pressure within the burner is gradually restored and, accordingly, the ame at 25 gradually recedes to its normal length. i It is to be noted that the torch head'24 extends .upwardly into the respective tube I'I and that, in use, the upper wall of the tube I'I overlies the torch head 24 and protects the same against quenching. Each tube I'I comprises a relatively short tube I'Ia supported on the hood I3 and opening through the respective opening I6 in the side of the-hood. The top of the inner end of the tube I'la extends inwardly into the hood beyond the bottom of the inner end of the tube and is secured at 32 to the flue I5. The outer end of the tube I'Ia may pass through the respective opening IB and may be provided externally of the hood with a down-turned lip 33. The outer tube IIb which, with the inner tube I'Ia, makes up each complete tube or conduit I1, is hinged in this particular embodiment to the hood I3 at 34 and is adapted to be swung into and out of alignment with the relatively short tube Ila. The hinge mounting 34 for the tube I'Ib may be of any suitable or preferred construction, and the hinged end of the tube IIb may telescope over the adjacent end of the tube Ila when the tube I1b is in alignment with the tube Ila as shown in full lines in Figure 2.

In the event that it is desired to remove the burner 6, or in the event that cleaning of, removal or access to the torch head or 'burner part 24 is desired, the overlying part of the tube I1 is removed from position over the torch head or burner part by swinging the tube Ilb upwardly about the hinge mounting 34 as, for example, to the position shown in dotted line in Figure 2 in which position cleaning and removal of the burner is permitted. Detent or latch means may be provided for holding the tube Ilb or the respectiv'e tubes IIb in raised position, or they may be held in this position manually or otherwise as desired.

It is to be understood that the torch head and lighter arrangement of Figures 1 and 2 may be of the gravity" type such as illustrated and described in the copending application of Oscar J. Leins, Serial No. 471,180, nled July 28, 1930, by providing the torch head 24 with-a second port diametrically opposite the port 25 and directed toward the pilot dame at the ports I3. In that case the flashing provision at the valve or coupling may be omitted and this valve may be a coupling for maintaining a constant pilot at the ports I3. When a burner 6 is to be ignited, the cock I0 associated with that burner is opened and gas enters the burner and is ready to be ignited at the burner openings 6'. Gas'also passes through the tube 23 to the torch head issuing therefrom in both directions, one stream of gas from the port toward and over the burner 6 and the other stream of gas through the diametrically opposite port above referred to toward and `to vthe pilot iiame at I9. The gas which ows toward the pilot iiame at I9 is ignited by the pilot ilame and the ameis conveyed back to the torch head 24, thus causing a ame to be projected over the burner 6 to ignite the gas issuing from the burner openings 6'. 35

In Fig. 3 the present invention is illustrated in connection with the gravity lighter illustrated and described in United States Letters Patent No. 1,747,015, issued February 11, 1930. In this case the outer end of the lighter tube I'I' which extends from. the hood I3'mounted over and protecting the torch head I2 on the upturned outer end of the lighter tube II', is provided at its outer end with a downwardly opening mouth 38 which overlies thevburner' to receive-gas from the burner openings when the cock associated with the burner is opened and to convey the ilame from the torch head I2' to the burner. In this case when the burner 33 is to be ignited, the cock associated with that bin'ner is opened and gas enters the burner ready to be ignited at the burner openings. 'I'he gas upon entering the burner passes up through the burner openings and those burner openings over which the mouth 38 of the tube I'I' is positioned cause gas to ow up through the mouth 38 and into the tube I1. 'Ihis gas entering the tube II' by opening the burner flows through the tube I1 to the pilot ame at the ports I9' of the torch head I2' where this gas is ignited by the pilot eo ame at the ports I0 and the flame is conveyed back to the burner 39 to ignite the gas issuing from the burner openings. As in the preceding embodiment, each tube II comprises an'outer tube hingedV at 34' and adapted to be swung into 65 the foot extension 4 I, the hollow interior of which 75 f extension 4i is in open communication with the interior of the burner I2. The upper end of the torch head 4I has diametrically opposite ports 44 and 45, one directed toward the pilot dame at the ports 45 of the torch head 41 on the lighter tube 45, and the other directed toward the burner openings 49.

In this case the lighter tube which extends from the hood l mounted over and protecting the torch head l1 toward the respective burner l2 is designated in its entirety at I. 'Ihe tube 5I comprises an inner relatively short tube section 5Ia and an outer supplementary tube section 5I!)l hinged at 52 to the outer end of the tube section 5|a and adapted to be swung into and out of alignment with the inner tube section 5ia for the purposes previously explained. The relatively short tube section Bia has xed support on the hood 50 extending through the openings 53 in the hood, which opening is directed toward the respective burner. `The top of the inner end of the tube 5la extends inwardly into the hood beyond the bottom of the inner end of the tube and is secured at 5l tov the flue' member 55. The longitudinal air slot in the bottom of the tube 5I is indicated at 55 and in use the outer end of the tube is positioned overthe foot extension 4| with the torch head l0 extending up through an opening in the bottom of the tube and into the interior of the tube below thetop wall thereof. y

The hinge mounting 52 in the embodiment of Figures 4 `and 5 is illustrated in Figure and comprises a pair of ears 58 struck up from the top of the outer end of the tube 5Ia and apertured at 59. A bracket 50 riveted, welded or otherwise suitably' attached at 5i to the top of the adjacent end of the tube section 5ib has an extension 62 which overhangs the adjacent end of the tube section 5Ia and is apertured at 53. In assembly the tube section -5lb is applied endwise to the tube section Sla which registers the apertures .53 with the apertures 55, and the pivot pin 5l is inserted 'through these registering apertures and headed or otherwise secured in place to hingedly mount the tube section 5Ibv on the outer end of the tube section 5Ia. The top 55 of the bracket 55 serves to cover the opening formedv in the adjacent end of the tube section Sla by striking the ears 58 up therefrom and the end of the bracket may be closed to complete this closure if desired. lhe extension or overhang of the pivotal mounting enables the tube sections to be brought together endwise into abutting relation without interfering with the swinging movement of the outer tube section 5ib.

It is understood that the present invention is not to be limited to the precise details illustrated and described.
