IGNITER WITH SPARK-EMITTING MASS.

Specification of Letters Patent. Patented Jll. 31, 1911.

Application filed October 21, 1909. Serial No. 523,839.

To all whom 'it may concern:

Be it known that I, JACQUES KELLERMANN,

manufacturer, citizen of Hungary., subject of the King of Hungary and Emperor of Austria-Hungary, residing at Berlin, in the Kingdom of Prussia and Empire of Ger; many, have invented new and useful Iniprovements in Ignite'rs with Spark-Emitting Masses, of `which the following is a speciiication.

My invention relates generally to igniters of that kind in which sparks are produced by friction and transmitted to a combustible body, such as a slo\v- 1nat`ch or a wick saturated With liquid fuel, and particularly to that kind of igniters in which the sparkeinitting mass is formed by a metalor alloy which scintillates when rubbed or scraped such as particularly, the alloys of cerium and the like.

A primary object of my invention is to provide igniters of the above described kind in which the arrangement of the sparkeniitting body and the harder rubbing or scraping body is such that these are located in a particularly favorable position relatively to the combustible body for igniting the latter at the moment When sparks are emitted. To this end, I preferably arrange the rubbing or scraping body such as a sharpened piece of steel close beside the coinbustible body, whereas l arrange the sparkemitting mass in such a manner that it 4can be moved relatively to the scraper and the sparks produced fall onto the` combustible body. ln order to assure that the sparks impact the combustible body in this manner, I prefer to arrange the igniferous parts in such a position relatively to the combustible body that the direction of motion while producing sparks by friction must cut the Zone of the flame to be produced.

Further, for assuring' the transmission of the sparks to the combustible body it is important to arrange that'at'tliemomen-t. of ignition the spark-emitting mass, such as a pyrophorus alloy or the like, is located directly at or close lto the combustible body,

'it being indifferent Whether it is moved, or

the scraper, or both simultaneously., For obtaining the same action, further, according to my invention I prefer to arrange the ,one of thev parts required for producing sparks, preferably the scraper, in a cham? ber in which the fuel evaporating from the combustible body collects in gaseous form when the igniter is closed, so that the sparks produced when rubbing said part With the otherA part required for producing sparks,n

preferably the pyrophorus metal, are produce-d in this chamber itself filled with combustible gases, and consequently these gases are ignited directly and on their 4part can ignite the fuel on the Wick.

A further object of my invention is to provide haildy, durable igniters of this kind Which can be manufactured cheaply.-

- Additional features of my invention will be understood from the following specification in connection with the accompanying drawings and from the claims.

Figure l is a longitudinal section through a closed pocket-igniter having automatic ignition; Fig. 2 is anend elevation of tlie same; Fig. 3 is a longitudinal section of thethis end, on the aXle\ around Which tie lid rotatesy isA arranged a' loose friction Wheel driven by means ofla pawl When the lid opens. The loose arrangement of the Wheel causes it to be driven only in the one direction, z'. e. when opening the lid, vvherea'sit remains stationary when closin the lid s 'o that no sparks are produced uring this movement.

Referring to the drawings, the lid 41 1s connected with the bottom part 42 of the casing by an axle 43, on Whichwis a loose Wheel 44 of steel or the like having on its periphery two kinds of toothing beside one another. Toothing 45 corresponds to .the ribs or teeth of a iile and serves for scraping the pyrophorus mass, Whereas the secon toothing 46 comprises ratchet-teeth. 4In theA part 45 of Wheel 44 so that ignition takes place certainly even when pin 50 wears.

In the form according to vIigs.' land 2 there serves as abutment for spring 51 a screw, 58, after removing which spring 52 lio and pin 50 can be readily removed through i the contrary, Amovable from the casing 42 is provided the hole 54 in casing 42 and exchanged. In l this constructional form the fuel reservoiri is formed by casing 42 itself. In the cong structional form according to Fig. 3, on

a special fuel reservoir 55 rethereby enabling small repairs to be made |l easier. In this instance tube 5l for the' pyropho'rus pin 50 is built into the fuel reservoir itself and traverses the saine. As abutment4 for spring 52 leaf spring 56 serves which holds the lid 41 in its closed position. A similar spring 56 is also provided in the forni according to Figs. l and 2.

For opening the lid autoinaticallyaspring i 57 is arranged on the rear Wall of casing j 42 beside the fuel reservoir; this sprin is 5 shown broken olf in Fig. l but in reality I presses against lid 41 in the manner readily understood from Fig. 3, so that by pressing l on button 58 of the spring 56 or 56 lid llis released and is subjected to the action of spring 57. Wheel 43 is driven byV its; engagement With paivl 45T and the file-like partof the same turns against the y rophorus pin forming sparks Which fly onto the wick 59. Instead of this wick an impregnated slow-match can be einplowed when, obviously, the fuel reservoir can be omitted, or I may arrange slow-match and l' wick saturated with fuel beside one another f in the same ivniter. y By arranglng the file-Wheel directly on the axle of the lid and employing the paWl, the intermediate gearing required otherwise is superfluous, the mechanism is simplied, l and the igniter cheapened and made lighter. l Also it is possible only in this manner to i use one single Wheel for providing the ratchet-teeth and the file-teeth or ribs, mali ing a special coupling superfluous. In- ,i

stead of the metal file-Wheel I may, however, employ a stone Wheel for producing sparks. y

Having now described my invention what I claim and desire to secure by Letters Patcnt of theUnited States is:

l. In an igniter, the combination with a casing, and a cover, of an axle pivotally connecting the cover with the casing, a scraping Wheel on said axle, means whereby movement of tlre cover will cause rotation of the axle, and a pyrophorus body bearing upon the scraping Wheel.

2. In an igniter, the combination of a. casing, a cover therefor, an axle pivotally connecting the cover to the casing, a scraping wheel on said axle, a ratchet Wheel on the axle, a spring-pressed paWl carried by the cover and engaging said ratchet Wheel, and a pyrophorus body Within the casing bearing against the scraping Wheel.

In a pocket-igniter a casing, a com-. bustible body Within said casing, a cover for said casing, an axle for pivotally connecting said cover With said casing, a scraping wheel loosely arranged on saidaxle, a pawl arranged Within said cover, a spring pressing said paivl into engagement lwith said Wheel When the igniter is closed.

4. In a pocket-ignitcr a casing, a conlbustible body Within said casing, a cover for said casing, an axle for pivotally connecting said cover with said casing, a scraping wheel loosely arranged 011 said. axle, two kinds of toothing beside one another on the periphery of said Wheel, the one. kind corresponding to the ribs of a file and the second toothing comprising ratchetteeth, a pawl pivotally arranged Within said cover and engaging'said ratchet-teeth, a locking device for said cover, a spring pressing against the inside of said cover and tending to open it.

In testimony whereof I have hereunto setmy hand in presence of two subscribing Witnesses.
