Slavin, Cleveland, Ohio, assignors. to The W. J. Schoenberger gililrinpanmflleveland, Ohio, a corporation'of Application February '24, 1933, Serial No. 658,450
" 6 Claims. (01. 158-115) This invention relates to a lighting device for gas burners and particularly to a device for use in connection with the burners of gas stoves.
The general object of the invention is to provide a lighting device for gas burners which will be simple in construction, and which may be conveniently mounted and readily removed as a unitary structure, I
With the above and other objects in view the invention consists of certain novel features of construction, combinations and arrangements of parts, that will be hereinafter fully described, and particularly pointed out in the appended claims; s
In the accompanying drawing:
Fi ure 1 is a top plan view of a conventional type of gas stove, the grille being broken away, showing the relative position of the burners and illustrating the application of -the improved lighting device;
Figure 2 is a section on the line 22 of Figure 1; I
Figure 3 is a fragmentary sectional view showing one of the gas and flame conducting tubes interlocking with aside wall of the hood. The
' dash-dotted lines showing the position of the tube before its interlocking with said wall;
Figure 4 is a sectional view on line 4--4' of Figure 3;
Figures 5 to 7 show perspective views of the parts of the hood before assembly thereof. Thus,
Figure 5 shows a perspective view of the cover; Figure 6 a perspective view of the housing and Figure 7 a perspective view of the member supporting the hood upon the pilot stem.
Referring more particularly to the drawing, the numeral I designates the top frame of a stove, including the usual grille 2, beneath which are mounted conventional main burners 3. Gas
is supplied to the burners 3 through tubes 5' provided with air mixers Ii and connected with a valved manifold or header I, in turn leading to a suitable source of gas supply; not shown.
The lighterof our present invention, generally speaking, comprises a lighter tube 8 connected at one end to the manifold I, and at its other end communicating with and supporting a Bunsen type of pilot burner 9. Mounted on the upper end'of the pilot burner, in a manner hereinafter described, is a-hood I 0. Tubes 36, one for each main burner 3, leading from the hood Ill to'the main 'burners convey gas from the latter to the pilot burner where the gas becomes ignited andconveys the flame back to the burners 3 to ignite or light the same. The pilot light preferably burns constantly and the main burners are ignited by the issuance of gas therefrom and therefore without flashing the pilot. Any suitable means may be employed for connectingthe tube 8 to the manifold and pilot, 5 such as sleeve nuts I I and I2 respectively.
The hood-l0, previously referred to, preferably formed of suitable gauge metal stampings,
comprises a bottom wall 28, upwardly folded side walls 23 integral with the bottomvwall, and' a removable capor top 24. The bottom wall 28 of the hood is formed with a centrally disposed opening 25 adapted to snugly receive the reduced unthreaded tip portion I5 of pilot stem M. The hood is rigidly supported on the stem It for freedom of vertical sliding movement to permit of ready removal thereof, by means of a centrally apertured supporting member 29, having upwardly extending projecting portionsfiil which 40 extend through narrow slots 3| in the bottom wall of the hood and are adapted to be clinched by banding the extended ends of the prongs back upon themselves against the upper'face of the bottom wall of the hood. The arrangement of the prongs and slots is such that opening32 in the supporting member will register with the opening 25 in the bottom wall of the hood when these parts are assembled. Member 29 is also formed with symmetricallyi arranged depending flat fingers 33- adapted to removably enter the recessed nut I9 and snugly engage or grip the flat polygonal faces 21 of sleeve-nut. 21.
In the prwent embodiment, the sleeve nut 21 is of hexagonalshape and the equally spaced fingers 33 are three in number, and correspond in width to the width of the faces 21 of nut 21.
Consequently the fingers will engage alternate faces with wrench like effect when the hood is mounted upon the pilot. serves not only to support the hood removably upon the pilot stem for rotary adjustment, but also provides convenient means for screwing up and unscrewing the sleeved lock nut 21 incident after any necessary adjustments will be so slight as not to interfere with the desired pilot flame action, as it will be seen that the hood can be rotated within a relatively wide range without causing any considerable change in height of the hood. The pilot will of course, always remain stationary, any slight vertical adjustment relative ,to the horizontal axis of lighter tube 8 being -made at the factory, by bending or arching the tube as at 35 to conform to the manifold and main burner set-up requirements submitted by individual stove manufacturers. When seated within the recessed nut I9, the fingers 33 are protected from the deteriorating and distorting effect of the heat, and consequently are not liable to become jammed.
Each side wall 23 of hood in is formed with a relatively large round opening 34 for loosely receiving the inner ends of the gas and flame conducting tubes 36, one for each main burner 3, which tubes are connected at their outer ends to the main burners. Fingers 31 depending from the top portion of the wall of each opening 34 are adapted to loosely enter or fit in openings. or slots 43 formed in the upper portion of the inner end of each tube 35 and thus hold the tubes removably in place, the tubes being free for slight-adjustment in any direction. These fingers are slightly bent at their lower ends in an outwardly direction, and preferably are sumciently fiexible to facilitate assembly of the tubes inthe manner illustrated in Figure 3, that is by tilting the tube upwardly to dotted line position to facilitate guiding the outwardly bent finger into its corresponding slot or opening 48, then lowering the tube to full line position, and finally forcing the tube and finger 31 inwardly to a slight extent. A reversal of this operation quickly disconnects the tube from the hood, however, there is no possibilityv of this happening accidentiy after the outer end of the tube is anchored in the main burner. Removal of the housing and tubes as a unit is possible without danger of the tubes becoming disconnected accidentally, particularly if the precaution to bend the fingers' 3'1 inwardly after assembly is observed.
The top or cap member 24 is secured to the hood by means of fiat projecting portions 50,
extendingv upwardly from each side wall of the hood, adapted to be inserted in correspondingly shaped slots 5| formed in the cover, and then of the cover as best illustrated in Figure 6.
In mounting the lighter, the hood can be rotated slightly in either direction to bring the tubes 36 into axial alinement with the burner openings 43, by merely loosening threaded 20 washer l8 and sleeve nut 21. The outer ends of tubes 36 can also be elevated slightly, due to the loose fit of the inner ends thereof in openings 34 in the pilot housing, so that nipples 42 can be conveniently inserted in the openings 43, 25 without danger of the tubes becoming disconnected from the housing during this operation. This loose fit also insures a desirable supply of secondary air to the pilot adjacent the point of gas discharge from the tubes 36. The pilot 30 housing I!) and tubes 33 are readily removable as a unit for cleaning or inspection purposes, and when so removed the tubes will be held 4 against accidental displacement by the fingers 31.
Having thus described our invention, what we 35 claim as our invention is:
1. In a lighter, the combination of a burner, a source of fuel supply therefor, a pilot, a housing for said pilot having an opening therein, a slotted tubular connection fitting loosely at 40 one end in the opening of said housing and at the other end communicating with the burner,
