To all whom it may concern:

Be it vknown that I, STEWART BROWN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented certain new and useful lImprovements in Electric Lighters for .Gas-Burners, of which the following is a specification. y

'This invention rclatesto electric means for lighting gas, generated from calcium carbid'or contained in a tank, as the same flews fron. a burnertip.' f

The'object of the invention is to obtain a device which can be appliedto lamps which are already in use, which will be economical in construction and installation, which consists of few parts, not liable to get out of order or yto be injured, and a device by means o1' Jwhich the vgas flowing from the tips of the burners of said lamps will be ignited byvthe heat generated in a resistance coil by a low volta e electric current on the circuitof "which t c devicej forms an element.

In the drawing Figure 1 is' an elevation of a burner and ofa4 device embodying this 'invention mounted thereon. v Fig. 2 is a top plan View of thezburner and device.

Fig. 3 is a vertical section of the base of the device on line 3*3 ofFig. 4, viewed in the direction indicated bythe arrows. Fig'. 4

is a top plan view `of the base of the device.'

Fig. 5 isa vertical section of the base viewed as in Fig. 3,1withl an elevation of some of the electric conductors' forming elements of the device secured in said base. F ig.'6 is an elevation of tubes forming elements in the device, viewed at an angle of 90 degrees from the view thereof illustrated in Fig. 1,r

40 with a resistance coil forming an element of the device 'mounted thereon. The several ii ures \of the drawing are on a scale much irgerthan the parts rep-` resented thereby.

throughout the several views.

is an ord ".nary acetylene burner pro-V vided with stent a and tips a and apertures a, of" inv said tips.

ends to the lower4 ends of the respective vtubes B. Wires C-are provided with bends c and C' L Similar letters referlzto similar parts*l B, B, are metal tubes respectively pro? D is a resistance coil. The ends (Z of coil Dare inserted in the upper ends of tubes B. E is a base made of fiber or other insu lating material. Base E is provided with groove e on the upper side thereof, (see Figs. 2, 3 and 4.-), with apertures'c there-y through and -with grooves e on the under side thereof. Grooves e are parallel and at right angles vtothe groove e. The apertures e and in grooves e and e.

6 are holes or wells communicating with grooves e respectivelyl F is a band around the stem of burner A and around base E. i 1

G is a thumb bolt extending through band F and through nut g. The inner end of the thumb bolt G is forced against the base E by turnin it in one direction in nut g and retracted rom said base on turning it in the opposite direction. The nut g isy preferably attached to the inner face of one end of band F, as by solder, to prevent its loss when the device is being secured to a burner tip. The front face of base E, lettered Hin Fig. 4, is curved to fit reasonably` close to the stem of burner tip A.

I is an insulating covering to wire C.

so 'l To assemble the device the tubesB are i of resistance coil D are inserted in the up-` per ends of tubes B (fitting closely therein), and bend b is made in said tubes and like bends are thereby made in ends d. Ends d may be soldered in. tubes B to makewgood electric connections, but if at any time when the device is in use the upper end s of the'A tubes become so yhot as ,to melt said solder (from the heat of the fiame of the gas from apertures a), the ends d will be held in tubes vB by bends l1),. and on the cooling of saidfjtubes the solder will again congeal. The band F bentafdescribed and having' hut g attached to one end'thereof is put in place on base E, and thumb bolt G is lnserted in said nut.

To install the device the thui'nbiniit G is removed and band F, Which is made of ductile metal, is Abent so as to pass .overy stein o of burner A, and the device is adjusted so that the resistance coil D is between the tips ai', and in substantially the position illustrated in Figs. l and 2 ofthe drawing. The' thiinib bolt il is then inserted in apertures.

provided therefor in the ends of band F and screwed into knut y unt-il the end thereot` presses tiri'nly againstbase E thereby seeiii= ing .the-device firmly 'to the burner. The

lresistance..coil D is iiiade et a wire of small diameter and presentingsuitable resistance to an electric currentso that itis heated by a current ot about six volts siitiiciently to ignite `acetylene gas flowing troni apertures o. v u i To use the device the vivii'estare piitl into a circuit, having an elpetific L'enivratiii' there` iii- (a (3-60 storage. battery oi-ioiir pi'iiiiiiry cells connected in series), and a't'tei' direct# ing a liovv ot gas through the burners the '.lhc gas will be thereby ignited. As the circuit ot which thisv device is an element is closed only-when the circuit is closed.

l. ln an electric igniter tor burners jtion.
