Among the objects of the invention is the provision of such an arrangement which can be economically manufactured and supplied to the trade at a. low cost, which provides a strong and adequate support and coupling for the flash tube, and which structure can be shippedfrom the manufacturer in disassembled relation and quickly and easily assembled at the time of installation.

A structure for carrying out the invention is disclosed in the accompanying drawing.

Fig. '7 is a view taken substantially on line 'I--'I of Fig. 4 showing the coupling relationship.

In Fig. 1 a portion of a gas range is illustrated including a frame or panel I, a gas supply pipe ormanifold 2, burners 3, each controllable by a valve 4; a supply pipe 5 extends to a substantially central location relative to the burners and its inner end is turned upwardly as shown in Figs. 3 and 4 where it may support the housing for the pilot flame.

There is a flash tube extending from the pilot flame to each burner here shown as comprising telescoping tubes, one end of each of which is like term oripl'aterformidzirisi seatedmmtop or the cup and it has apertures l4 therein through which tabs'or extensions I5, rising from the upper edge of the cup, extend, and these are turned over as illustrated in Figs. 2 and 3 to hold the support in place. This support member has a substantially central opening [6, and the member may extend somewhat inwardly from the periphery of the cup to partially close the cup and to aid in the protection of the pilot flame.

The outer portion of the support extends laterally beyond the walls of the cup and is provided with an arcuate slot arrangement for coupling with the tubes. As shown, the support has two arcuate slots 20 each extending almost 180, and where there are four burners, two of the flash tubes are coupled with each of the slots. This slot formation results in a relatively narrow outer strip of metal adjacent the edge of the support as shown at 2 I. By providing two slots connected to the body of the support by the integral metal 22, a strong construction is obtained, but, as indibe turned. The metal may be bent substantially through as illustrated, and the lower end of theflnger has a bend formation, or curved lip formation, 21. This projection is advantageously positioned back from the end of the tube in order to utilize as much of the metal of the tube as is possible. The flat portion 25 forms no substantial constriction of the tube but merely provides a section of metal with a plane surface so that the finger 26 may be bent therefrom. The

end of the tube is cut away somewhat as illusat right angles to the plane of the support is revented as the lip engages on the under side of the support. Detachmentcan only be 'efl'ected by a reverse of the assembly operation, namely by tipping the tube to an angular position similar to that shown in Fig. 6.

The width of the finger 26 is substantial as shown in Fig. 7 so that it relatively snuglyengages inathe slot.. This prevents pivotal action ofthe tube relativeto the support around the'lfinger as an .axis. Thewidth of the finger causes its edgesto engage against the walls of the slot 50 that it cannot tum in theslot; ever, the projection may shift bodily in the slot by movement .arcuatelyi around the pilotflame as a center, with the result that the tube is maintained in asubstantially true radial position, re-

ardless of variation in the location of the burner. V

- The pilot flame is=wellcprotected by the cup as shown in-Figr'3, and indeed the pilot flame pref erably quite I How- Thus the curved lip underlies the support, and detachment by movement of the tube out through the end thereof and across the top,

of the flame and it will be ignited even though the flame is well down within the cup. However, if the flame is of such height as to extend upwardly above the support and within the plane of the tubes, it is only the upper end of the flame which'is subjected to the flow of gas, with the result that any tendency to extinguish the flame 'is minimized.

I claim: In a lighter for one or more gas burners wherein there is a substantially continuously burning I (pilot .flame'and a flash tube extending from the need-not extend above-the level of the support. I

When gas is supplied to: one of the burners such gas is transmittedfthrough the flash tube and pilot flame to each burner to be lighted, a hous- .ing ,for the pilot'fiame substantially in the form of a" cup," a disc-like supporting member secured 'tothe top of the cup and having a central open- .ing'substantially concentric withthe flame and partially closing the top of the cup, the outer portion of the supporting member'extending radially outwardly of the cup and-beingprovided with-one or more concentric'iarcuateslots; each tube having a flat .formationon one side adapted torest'upon the-supporting member and having a downward projection provided by a down turned piece of metal ofgreater width than'the slot, arranged to extend-through the slot for slidable and. non-rotatable connection, the pro- 1 jection having-a bend .Iormation. on its 'endfor engaging under the supporting member, the projection being" engageable. and disengageable from the slot by a swinging movement of-the tube,sub-. stantially in avertical plane. g
