use the same.

This'invcntion relates to lighting devices of the class used for lighting gas burners and for similar purposes, and the object of the invention is to provide an improved device of this class which is simple in construction and operation, and winch may be conveniently manipulated, and with thisv and other objects in view the invention consists in a device of the class specified,.

constructed as hereinafter described and claimed.

, The invention is fully disclosed in the, following specification, of which the itCCOIlI- panying drawin forms apart, in which the separate parts 0 my improvement are designated by suitable reference characters in each of the views, and in which;

Figure 1 is a side view rof my improved lightmg device and showingth'e parts thereof in position for use -Fig.,2 view' similar to Fig. 1, but showing the parts in a ditl'erent position ;F;ig. 3a view-looking in the direction of arrow 3 of :Fig. 2;-Fig.';4 a view similar .to Figs. 1 andQ, but showing only a part of the device, and showing the parts thereof in a different position,;-Fig.

' Fig. 7 a View similar to Fig. 4:, but showing only one part of the device and showing one step in the formation thereof, and ;-Fig. 8 a view of that part of the device shown in Fig. 7 and showing another step inthc formation thereof.

In the practice of my invention I provide a lighting device of the class specified, the general form of which is old and well known and which comprises a main spring arm a and a supplementalsp. ing arm I) connected atone end by an open sprlng ring a formed integrally therewith and the end of the arm tr is provided with a semicircular head a having across bar d, one side of which is provided with a file or roughened igniting surface as shown at (2 and all the parts a, b,

0 undo are preferably composed of a strip of flat spring metal.

The end a of the semicircular head a or of the bow which forms said head, is beveled at one or botlr edges thereof as shown at a and the object of this construction will be hereinafter described.

The free end portion I) of the supplemental spring arm Z) is bent or turned at right angles to the main part thereof and is bent on the transverse line 71 shown in Fig.

7 to form a head piece I) of double thicknoss, but before bending said part b at I), the extreme end portion 1) is tapped to form an aperture b and after the bending of the end portion I) to form the double head I)", the

said head isslotted longitudinally as shown at U to form two spring jaws b as clearly shown in Figs. 1, 2, 4and 8.

I also provide a scratch or igniting plug 0 which, in the operation of the device, bears -on the roughened surface d of the bar (Z and which produces sparks by which the gas is ignited.

The Plug e is of well known material and similar to other devices of its class now in use and said plug is provided with a neck portion e which fits in the aperture I) and said neck portion bears on the upper side Z1 of the head L, while the head of said plug bears on the inner side 31 of said head, as clearly shown, and the action of the spring jaws b of said head securely hold said plug in position.

In order to remove the plug 6- or substitute a new one, the device is laid on a table or other support and the spring arm I) is swung into the position shown in Fig. 1 and pressed downwardly so that one of the beveled edges at a? of the semicircular head a will enter the slot 1) in the head I) and force the jaws 'removed as will be readily understood.

My invention relates particularly to the formation of the head I) and the slotting thereof together with the diminution of at least one edge of the end portion a of the semicircular head a of the arm a so as to facilitate the attachment and detachment of the plug 6.

The operation of this device will be exactly the same as others of its class now in use.

In order to ignite a gas jet, the arm 6 is swung into the position shown in Figs. 1

and 6, in which position the scratch orignitmg plug 6 bears on the bar (Z which forms the other scratch or igniting member as v shown in Fig. 6, and the arms a and Z) being one end, one ofsaid arms being provided at its free end with atransverse bar and the other with a head adapted. to bear thereon, said head being provided with a longitudinal slot forming" two spring jaws, and a scratch or igniting plug detachablymounted between said jaws.

2. A lighting device of the class described comprising two spring arms connected at one end, one of said arms being provided at 'its free end, with a transverse bar and the other with a headadapted to bear thereon, sald head being provided with a longitudinal slot forming two spring jaws, and a scratch or igniting plug detachably -mounted between said jaws, and said device being also provided at one end of said transverse bar with a reduced edge adapted to enter the slot in said head.

3. A device of the class described provided with a spring arm having a longitudinally slotted head. composed of two parts folded I one upon the other, one of said parts being provided in the plane of the slot with an aperture, and a scratch plug having a neck adapted to enter said aperture.

i 4-. A device of the class described comprising two spring arms one of which is bent at one end to form a semicircular head in which 'is mounted a transverse bar, the end of the bend which forms said semicircular head being provided with a beveled edge, the

other spring arm being provided with a -slotted head forming spring jaws between which is1 detachably mounted an igniting scratch Iii testimonythat I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 6th day of February 1911.
