Application filed April 12, 1913. Serial No. 760,629.-

To all whom it may concern.

Be it known that 1, MAX HENDLER, a subject of the Czar of Russia, and residing at reference being had to the accompanying drawings, forming part of thisspecification,

in which'-- Figure 1 1s a side elevational view of a miners lamp equipped wlth my improved lighting device.

Fig. 2 is a front elevational VieW of the lamp with the lighter applied to the reflector thereof. v

Fig. 3 is an enlarged horizontal sectional view taken approximately on the line 33 of Fig. 2.

Fig. 4 is a perspective view of a combined bearing and holder made use of in my improved lighter.

My invention relates to a lighting device particularly intended forall forms of gas burning lamps, the principal object of my invention being, to provide a simple,-inexpensive and convenient lighter which. can

be applied directly to the reflector of the.

lamp adjacent to the burner tip, and which lighting device, when operated, creates a spark which is thrown directly across the gas issuing from the burner tip, thereby igniting said gas.

My invention, while primarily designed for use in connection with the ordinary forms of miners acetylene lamps, can be advantageously combined with all forms of gas lamps.

To the above purpose my invention con sists in' certain novel features of constructionand arrangement of parts hereinafter more fully described and claimed.

Referring-by numerals to theaccompanyingdrawings, 1 designates the, body of a ininers acetylene gas lamp of the usual construction and comprising gas-generating means, not shown, said body being. provided with a gas outlet tube or burner tube2 in the outer end of which is seated a perforated isadj u stahlyneated on the tube 2, and

Specification of Letters Patent.

formed through this reflector adjacent to the burner tip 3 is a threaded aperture, and there being a flange or collar 6 formed integralwvith said reflector around this aperture. Screw-seated in this threaded aperture is the threaded rear portion of'a combined holder and bearing 7, which constitutes part of a p'yrophoric ignition attach ment and which .is in the form of a short tube, the forward end of which is blfH-l cated or slotted to form a pair of fingers 7. A small disk 8 is positioned between these fingers 7 and is mounted for rotation on a pin 9, the ends of which are seated in said fingers 7 'The edge of this disk 8 is serrated or provided with a series of sharp teeth. In the particular construction illustrated, this disk or spark wheel is located in a radial plane with reference to the burner tip and projects somewhat outside of the plane of the reflector edge.

Screw-seated upon the projecting rear end of the holder and bearing 7 is a cap 10, and

positioned. therein and in the rear portion of .the tubular member 7 is an expansive coil spring 11. 'Arranged-to slide freely through the forward portion of the member 7 is a short, cylindrical section of metal 12,. or a combination of metals, which will readily give off sparks of fire when engaged by the edge of the disk 8 as the latter is rapidly rotated.

" The tubular holder is screw-seated, and

' forward end of the burner tip, and thus the sparks produced as the disk is rotated are thrown directly across the mouth of the gas exit opening in said burner tip. I

The operation of my improved device is apparent, for it is only necessary to plaot the thumb or finger on the serratededge of the disk 8 and -to partially rotate said'disk with a quick motion,- and. as a result, the teeth on said disk scrape across the forward end of the section of spark-producing or pyrophoric material, and as a result, sparks of'fire are produced which are thrown directly acrossthe orifice in the burner tip 13. thereby igniting the gas as it issues therefrom. As the sparkproducing material wears away it will feed forward under "the -119 v influence of the spring 11, and the tension of this spring can be regulated by a manipulation of the screw cap 10.

lliioreover, it is evident that the relative position of the spark wheel with respect to the rim of the reflector is such that the lamp can be lighted by a sweep of the palm of the hand across the face of the reflector in contact with the spark wheel. Thus, when the palm of the hand is wiped across the periphery of the spark wheel, either while also engaging the reflector edge or not, the wheel will be rotated and the pyrophoric ig' nition attachment operated to ignite the giis issuing from the tip end oi the burner tube. it is also evident that the palm of the hand may be held against the reflector edge in such manner as to close the reflector and accumulate a combustible gas mixture therein; and that the hand may then be wiped across the reflector edge to engage the wheel periphery and cause rotation thereof, thus efiectiug operation of the pyrophoric attachment and ignition of the accumulated gas.

The tubular member 5 carryingthe reflector and the spark producing means is adjustably )ositioned on the tube 2 in order that the re ector may be rotated upon said tube 2 to bring the spark producing means above, below or to either side of the burner tip 3, thus making it possible to obtain the full benefit of the light from the ignited gas on the work upon which the miner is engaged; for instance, if the work is at the top of a drift or horizontal passage way, the reflector is turned so that the spark producing means is located below the burner tip or, if the miner is working close to the floor oi. the drift, the reflector is turned so that the spark producing means is positioned above the burner tip.

A device of my improved construction is comparatively simple, is very compact, 0c n pies little space on the face of the rellector, and is adapted for use in connection with all gas burning lamps.

lt will be readily understood that minor changes in the size, form and construction or the various parts of my improved device can be made and substituted for those herein shown and described without departing irom the spirit of my invention, the scope of which is set forth in the appended claims.

l claim:

l, The combination with a lamp of the charac er described, having a reflector surrounding the burner tip of a lamp, of; a tube seated in the wall of the reflector and extehdinc rearwardly of the same, the inner end of? said tube being provided with spaced ears proj ecting inwardly from the reflector wall, an 11hr re wheel rotatably mounted be tween so ears, and. having its axis disposed in a p no {'tt right angles to the longitudinal am-sea axis of the reflector, the periphery of said wheel projecting beyond. the plane of the outer edge of the reflector wall, a stick of sparking material slidably mounted in the tube, a spring arranged. in the tube and bearing against the sparking stick to force the same info frictional engagement with the abrasive wheel, and a cap threaded upon the end of said tube to removably retain the spring therein and adjust the tension thereof.

2. In an acetylene lamp, the combination of a body part, provided with. means for generating gas, a reflector supported on the body part, a burner within the reflector for receiving the generated gas, and pyrophoric ignition attachment comprising a spark wheel, said mechanism being so positioned with reference to the plane of the outer edge of the reflector that when the palm of the hand is wiped across said retlector edge it will engage with the periphery of the wheel to cause rotation thereof and operation of the pyrophoric ignition mechanism to ignite the gas.
